Commissioning Solutions towards Sustainable, Energy - Efficient

Building Performance

Introduction

The commissioning phase of any project is often key to the sustainable, comfort and

environmental, performance of a building, vis-à-vis the system design.

It is well known that over the life of the equipment, just the energy cost of operating and

maintaining present building HVAC services are 5 to 10 times the total equipment cost.

Hence the importance of focused design and commissioning portfolios cannot be

overstressed.

Reef Tech Services L.L.C. acknowledges its responsibilities in this regard and has set

standards which will easily maintain the high standards expected by the building services

industry in the UAE.

Our aims are primarily to meet the ever growing commercial demand for practical

experience and professional expertise within this sector.

Commissioning Controls Procedures

The engineering procedures to be adopted are detailed elsewhere in this document, however the following are the general terms adopted and the associated control procedures. A. Pre Commissioning Checks Pre-commissioning checks are those made immediately prior to commencement of commissioning to ensure that the plant and equipment are installed in a safe and satisfactory condition to enable commissioning to commence. Each system shall undergo a static check using the standard company proformas, TS1 or TS2. Pre-commissioning proformas list the aspects of the item of equipment or system which require inspection while in static state, prior to “setting to work” and includes such items as:

a) Cleanliness. b) Completion of the installation. c) Status of regulation devices. d) Alignment of components. e) Security of components. f) Free rotation/movement.

Any non-conformity identified during the static checks shall be recorded on the appropriate proforma and the client’s representative informed the action. All non-conformities shall be resolved and re-inspected before proceeding to the “setting to work” stage of the commissioning process.



REEF TECH SERVICES

B. Setting to Work The “setting to work” of a system is defined as the process of setting a static system into motion. It is essential for systems comprising of a number of items of equipment or sub-systems, that the “setting to work” of each component of the system be carried out systematically. The sequence of activities must therefore be identified on the commissioning programme or logic diagram. The priorities for the “setting to work” of individual components within a system will normally be as follows:

a) Frost protection and other such protective devices. b) Water tanks.

c) Water softener/demineralisation systems. d) Pressurisation/water nake-up units. e) Circulating pumps/air handling units. f) Boilers, chillers/cooling towers g) Secondary equipment-calorifiers, humidifier, heater. h) Controls.

Note Unless forming part of the vital protection or interlocking function, controls are normally by-passed and the system manually adjusted or statically set during the “setting-to-work” phase of commissioning. Provided adequate planning and co-ordination is achieved, the commissioning of controls is one of the few activities which may proceed in parallel with the overall commissioning process. Final commissioning of HVAC controls will normally only be possible after the completion of both the “setting-to-work” and regulating phases of individual systems. Before proceeding with the act of “setting to work” an item of equipment or system, the Engineer in charge shall ensure that:

a) All pre-commissioning checks and proformas are complete. b) All non-conformities are resolved. c) All electrical checks are complete. d) Mains water/gas/electricity are available. e) All essential interlocks/safety devices are operational. f) He is familiar with the operation of the complete system. g) Before starting the regulation, it is essential that the building is complete,

ceilings, partitions, doors and windows installed, windows glazed, doors or windows in their normal or closed state.

h) All site personnel are made aware of the commissioning activities and that they are not affected.

i) Adequate warning signs are displayed. j) If required by the conditions on site, a permit-to-work system has been set

up.



REEF TECH SERVICES

The initial running of any prime mover shall be carried out under strict control and limited load conditions, by adjusting the system flow rates. In addition, the “setting to work” of equipment shall be broken down into the following distinct stages:

a) Initial start/stop (check direction of rotation). b) Initial run on light load. c) Starting at normal load. d) Running-in period (normal load)

During the running-in period the Commissioning Engineer shall complete the appropriate equipment checks and test proformas and compare the actual data obtained under normal load running conditions with that of the design data. Any malfunction of the equipment or non-conformity between actual design data shall be analyzed and a solution obtained before proceeding with regulating phase of the commissioning process. Any equipment which is unable to achieve the design requirements with the regulation devices in a “fully open” position prior to regulation of the system will almost certainly require up-grading. Where possible, up-grading of the equipment shall take place prior to the regulating of the system. Details of “setting to work” of individuals system are detailed elsewhere in this statement. The inspection authority shall be asked to witness and sign the completed equipment performance test proformas. C. Regulation and Balancing of Distribution Systems Regulation is the process of adjusting a system within specific tolerances. Regulations of a system shall not commence until the satisfactory completion of:

a) All pre-commissioning checks and proformas. b) The “setting to work” of all associated equipment.

All regulating and balancing of air and water distribution systems shall be carried out in line with one or more of the following guides:

a) CIBSE Commissioning Codes for Air and Water. b) BSRIA Application Guides Nos. 2/89, 3/89 and 1/91.

The Engineer in charge shall ensure that he is fully conversant with every aspect of the above codes of practice. The final results of regulating a distribution system shall be recorded on the standard company or other approved proformas and signed and dated by the Engineer concerned at the time of carrying out the regulation.



REEF TECH SERVICES

Proformas used to record commissioning results shall be the company proformas on all projects except where the client decrees otherwise. Any non-conformity in the regulation of a system shall be analyzed and corrective adjustment or action taken by the Commissioning Engineer immediately. The Commissioning Engineer shall be responsible for informing the client’s Supervising Engineer of the failure of a system to achieve an acceptable standard of regulation. On ascertaining the reason for the non-conformity, the Commissioning Engineer shall report in writing, stating the reason and recommending any corrective action necessary to resolve the matter. The client’s representative shall be responsible for arranging any action necessary to resolve the non-conformity and shall inform the engineer in charge when the corrective action has been taken. After satisfactory regulation of the distribution system and completion of the appropriate proformas, the engineer in charge shall arrange for the witnessing of the system by the client’s representative or the appointed inspecting authority. D. Achievement of Conformity at Commissioning The process of undertaking the regulating and balancing of a system will identify any non-conformity in respect of fluid flow and circulation. The responsibility of the company will be to identify the non-conformity, notify the client’s representative, offer any relevant information in respect of the likely cause of the non-conformity and establish the necessary rectifying actions. The responsibility in respect of initiating any rectifying action will always lie with the client. The likely cause of any non-conformity is likely to be due to one or more of the following:

a) An error in conceptual design. b) An error in system design. c) An error in detailed design. d) An error in equipment selection. e) Shortcomings in supplied equipment. f) Changes in system geometry imposed during the installation. g) Changes in system geometry imposed by variations. h) Sub-standard workmanship. i) Dirty pipework or inadequate water treatment.



REEF TECH SERVICES

The solutions to the non-conformity are likely to involve one or more of the following actions:

a) Modification of the installation. b) Replacement of equipment. c) Concession by the client. d) Cleaning of pipe work and review of the water treatment.

E. Witnessing and Signing of Results After the satisfactory completion of the commissioning of an individual system, the Engineer in charge shall ensure that the relevant documentation is complete and free from error, before arranging for witnessing by the inspection authority. The Engineer in charge shall be responsible for ensuring that the inspecting authority is notified of the readiness of a system for witnessing and at the same time, submit a copy of all relevant results for preliminary inspection. Adequate notice shall be given to the inspecting authority of a request for witnessing. The method statement may specify a minimum period of notification prior to witnessing. It is essential that every effort be taken to ensure that the witnessing of a system by the inspecting authority be instigated immediately following satisfactory commissioning. The Engineer in Charge shall inform the client’s representative of the completion of the commissioning of a system, and the client shall be responsible for ensuring that every effort be taken to protect the system from interference prior to witnessing taking place. After successful witnessing of the system, it shall be the responsibility of the Engineer in Charge to obtain the signature of acceptance from the inspecting authority. In the unlikely event of the inspecting authority not signing acceptance of the system, the Engineer shall confirm in writing the successful witnessing of the system and request confirmation by the inspecting authority. Witnessing of individual items of equipment or component parts of an overall system shall, where possible, follow on systematically and within a reasonable time period. Under no circumstances shall the signing of an accepted system by the inspecting authority be delayed until after the satisfactory completion of all the commissioning activities. Where possible, any system which is dependent upon another shall be signed “subject to” the satisfactory completion of that system.



REEF TECH SERVICES

All documents shall be held in a secure place, and on completion of the witnessing of a total system, an acceptance certificate shall be issued and signed by the Inspection Authority. F. Post Commissioning Activities The commissioning is not deemed to be complete until the following activities have been completed:

a.) Making good the installation.

b.) Test documentation finalized and handed to client.

Making Good The Engineer in charge shall be responsible for ensuring that the following aspects are made good immediately following the satisfactory completion of the commissioning:

a) All ductwork test plugs are fitted. a.) Pipework test points are plugged. b.) Access doors/manholes are replaced. c.) Pulley guards are replaced. d.) Controls/panels are re-installed. e.) Inhibiting devices are removed. f.) Ceiling tiles replaced (if removed by Engineer) g.) Insulation or other damage reported to Project Manager. h.) All controls and equipment set to operate in auto. i.) Temporary equipment removed. j.) All regulating device positions marked and/or recorded on the

appropriate proformas. k.) Gauges replaced. l.) Controls and equipment covers replaced. m.) Any other aspect of the installation requiring rectification as a result of

commissioning.

Setting to Work. A. Precautions against airborne dirt Others shall have cleaned the system internally, and verification obtained from the Supervising engineer. B. Initial Running of Fan Set To reduce the initial load, main plant damper should be partially closed to reduce the possibility of overloading. On activating the motor we will check:

a) Direction of rotation of motor shaft. b) Motor, drive and fan free from vibration or undue noise. c) Motor starting current for sequence timing adjustment. d) Motor running current on all phases.

1. Initial Run The light load will be sustained for an initial period until the Commissioning Engineer is satisfied that stable conditions exist, there after further load shall be applied until full load is established. 2. Normal Load Running On conclusion of the initial running period and normal load being achieved, the unit will be stopped and restarted at normal starting load, and the running checks repeated. A running in period will now be established until the Commissioning Engineer is satisfied that the fan can be placed under the normal operation system. Regulation of Air Flow A. Method of Measurement All airflows will be based upon in duct measurement of velocity pressure using manometer and pitot tubes. Vane anemometers will be used to balance between similar air inlets and outlets on a comparative basis, and corrected by comparison to in duct velocity measurements. All other instrumentation and measuring techniques will be as described in BSRIA Application Guide 3/89.



REEF TECH SERVICES

1. Method of Air velocity in Ducts

a) Test holes Test holes, where not already provided will normally be formed by drilling 3/8” dia. clearance hole, and will be sealed by insertion of removable tapered plastic plugs.

Test holes will preferably be located a minimum of ten diameters downstream from any source of disturbance to air flow. The number of test holes will be determined by size and shape of the duct to be measured. The positions for taking readings are set according to a convention known as the Log Tchebycheff rule, which governs the strict positioning of the Pitot tube within the duct.

b) Rectangular ducts

Ducts of width of less than 1500 mm, will have test holes on one side only, for widths in excess of 1500 mm will need test holes positioned on the centre line of each row of areas. A minimum of two measurements should be preferably taken, and the normal spacing on large ducts will be 150 mm minimum, 300 mm maximum. A measurement of velocity is taken at the centre of each of the equal areas and averaged to establish the obtained velocity. Total airflow will be the multiple of the obtained velocity and the total cross sectional area.

c) Circular ducts Circular ducts will have test holes drilled to make traverse in accordance with the following table. Where two traverses are required there shall be on two diameters at right angles to each other at 0 and 90 Degree positions. For four traverses, test holes will be required at 0, 45, 90, and 135 Degrees respectively.

Table for measurement of velocity in circular ducts

2. Measurement of Airflow at Terminals The nominal means of measurement at terminals is by means of a vane anemometer. It is recognized that the application of a hood to a terminal fitting will

slightly increase the system resistance and thus reduce the discharge rate at the terminal. It is general that the resistance of the instrument will be small, and the application of a correction factor developed of an instrument in the particular application will make an adequate adjustment. The correction factor will be determined by comparison of the anemometer reading to an absolute reading, in practice probably a duct pitot traverse at a location producing stable airflow, using a calibrated instrument for the measurement refer Test pro-formas for correction factor. The preferred situation is that in any balancing exercise only one instrument is used. In some instances, because of a wide diversity in airflows from terminals and significant differences in size and type of terminal on the one system, more than one instrument may have to be used. This may be unavoidable, and can be acceptable provided full consideration is given to the preparation of the correction factors. Although the primary effect of the use of the instrument will be to depress the measured value i.e. producing a correction factor > 1, because in the application, the factor will compensate for instrument variation as well as the instrument effect, the final factor may often be < 1. In practice correction factors that fall within a range of + 20 %, would be anticipated. If correction factors exceed these parameters, they need not be rejected, but an explanation of why such a wider deviation has occurred needs to be appraised. The intelligent application of experience and a sound technical knowledge is required from the test technician in evaluating the acceptability of his correction factors. If there is a wide variation in type of outlet on a system, it may be prudent to develop a different factor for each type. B. Regulation procedure Before starting the regulation, it is essential that the building is complete, ceiling, partition doors and windows installed, windows glazed, doors or windows in their normal or closed state. If spaces are not architecturally sealed, abnormal pressure distributions will unbalance the system and lead to inconsistent and un-reproducible results. 1. Proportional Balancing The method of regulation will be the proportional method as set out in CIBSE Code A.

The successful application of the proportional technique is dependant upon the inclusion of sufficient regulating dampers, suitably positioned in the ductwork system.



REEF TECH SERVICES

The premise for the procedure is that in any branch element of the system, the quantity of air passing through each terminal will represent a proportion of the total flow in the branch. Unless the terminal regulating dampers are altered, these proportions will remain the same, within practical limits, whatever the flow rate in the branch.

To balance one terminal against another it is, therefore only necessary to adjust the regulating dampers so that the terminals share the flow in correct proportions. It is not of the significance what the actual flow is during the interim regulation. Then the main flow from the fan is regulated to its design value, each terminal should also be passing at its design flow rate, since each has been set to take its own proportionate share. a) Index branch and least favored branch Care should be taken in differentiating between the index branch and the least favoured branch in carrying out the balancing process. Whilst nominally they have a similar definition, they need not be the same in practice.

Index branch This is defined as the branch which, with the system in an unbalanced state i.e. all dampers fully open, has the greatest resistance relative to its design flow rate when compared with the other branches forming part of the same system. A branch may have a number of sub branches. For each branch there will be an index sub branch, similarly each sub branch may have a number of terminals, one of which will be the index. Once established, an index branch will be known as such throughout the balancing process. At the end of the process, there should be a clear path from the fan to the index terminal, where all regulating devices are set full open. There is a need to provide for the circumstance where the index is not the most remote terminal. In proportional balancing, it is essential that on a system or sub system being balanced, that the most remote terminals must initially be regulated down until it is made equal to the index. When this is done the most remote terminal can be regarded as equivalent to the index. The true index has its regulating damper fully open and must remain so, but the most remote terminal is the reference index terminal for the balancing procedure. b) Preliminaries

a) Open all duct system and terminal dampers, ensuring that the fan output can be limited and an overload situation does not occur. Set all diffuser cones to give full downward discharge, Set adjustable grille louvers at right angles to the grille face. Set plant dampers to a non-modulating position preferably full fresh air/discharge.



REEF TECH SERVICES

b) Run the fan and check the motor current. Ensure that its design full load value is not exceeded. Adjust the main fan damper until the fan motor current is close to the design value.

c) Undertake preliminary inspection checking that air flowing at each terminal. Any dead terminals or branches should be investigated.

d) Measure the total flow rate at the fan by a duct pitot traverse, the fan head and rotating speed. The fan should be delivering at 110% of the design value.

c) Rough balancing of branches

Measure the flow in the main branches A B & C. Having worked out the percentage of design flow rate for each branch, determine which branch is the index, i.e. the one with the lowest percentage of its design flow rate. If this is not the most remote (branch A), then adjust the flow to branch A until it has just the lowest percentage flow rate relative to the index. If the difference between the highest and lowest percentage flow rates for the branches is more than 30 %, adjust the dampers to bring the flow rates within this limit but still maintaining branch A as the one with the lowest percentage flow rate. Once the main branches are in a rough state of balance, the sub branches should be tackled next. Starting with the most remote branch (branch A), measure the flow rate in the entire sub branches A1, A2, A3 etc. Check that the sum total of all the sub branch flow rate equals the main branch flow rate already measured. Any large discrepancy should be investigated. Work out the percentage flow rates for each branch and check that the most remote (A5) is the lowest. If not, make A5 the least favored by dampening down. Again, check all branches on branch A to see that their percentage design flow rates are reasonably close to each other. If the highest and lowest values are more than 30% apart, adjust the appropriate dampers to bring them nearer together. Repeat the coarse balancing of sub branches for each of the remaining main branches, B and C. Check the total flow rates in the main branches again and adjust if necessary to make the most remote (A) the least favored. Sum the main branch flow rates to check that the total flow rate in the system is not less than 110% of design. If the total flow has dropped below 110% of design, adjust the main damper accordingly or increase the fan speed. d) Balancing Terminals Any main branch may be chosen to start with but given a free choice, and having carried out a rough balance of main and sub branches, start with the most remote branch and then sub branch, i.e. A5 in figure on page. Locate the terminal, which is discharging the lowest percentage of its design flow rate. This is generally the last terminal in the run. If it is not , adjust the damper in the last terminal unit until it is working with the same percentage flow as the lowest one previously measured.



REEF TECH SERVICES

Measure the flow from the terminal next to the index and work out the percentage flow. Adjust the damper to make the percentage flow as close as possible to that of the index. Fix the damper in position. Repeat the procedure for the next terminal, again comparing it with the index. As the dampers are closed along the run, more air will be given to the downstream terminals and the volume of air discharged at the terminal index will rise. This does not affect the balancing procedure since each terminal being adjusted is related in turn with the index. When all the terminals have been balanced on a sub branch, each terminal will be running with an equal percentage of the design rate, within the allowable tolerances. The flow rates at each terminal must be measured and recorded. Once again a summation should be made to check that the total is in reasonable agreement with the measured sub branch flow. e) Balancing Sub-Branches When all the terminals on each sub branch have been brought into balance, the sub- branches should be brought into balance with one another using the same techniques as for the terminals. Ideally this is done by traversing each sub branch first to determine the index sub branch, which should be the remote. Again, if the one end is not the index, then it must be made the least favored by dampening down. Having made the initial traverses by pitot tube to establish absolute flow rates, it is often possible to speed up the process of regulation by one of two methods to save repeated traversing. If the traversing stations are well downstream of sub branch balancing dampers, and a centre point reading of static pressure is of reasonable size, then, using the square law relationship between static pressure and flow rate, the flow rates can be simply adjusted using static pressure measurements. If the sub branches each have a similar type of terminal, then a single terminal on each branch can be used to obtain an anemometer reading as a basis for bringing the sub branches into balance. It should be noted that the two techniques described above should be used with great caution and, in any case, only when, the sub branches have been brought into fairly close balance by the initial course balancing procedure. f) Balancing Branches The main branches (A, B and C) are brought into balance by the same method as for the sub branches. As with the sub branches, suitable static pressure measurements in each branch can be used to bring the branches more quickly into balance but final results must be obtained by pitot traversing.



REEF TECH SERVICES

C. Final Correlation When the entire duct network is balanced, measure the total flow in the main duct using a pitot tube and manometer. If the flow is higher than the design value, adjust the main damper. If the pressure drop across the main damper in the final position is a significant part of the total system pressure drop, a reduction in fan speed should be considered. If the flow is less than the design rating, open the damper, making sure that the maximum permissible fan motor current is not exceeded. If the flow rate is less than the design rating, open the damper, making sure that the maximum permissible fan motor current is not exceeded. It is essential, whilst using the proportional balancing technique, that absolute flow rates are calculated from time to time during the procedure and at the end in order to ensure that there is satisfactory correlation between the flow rates from terminals in sub branches and branches and the total system flow rate. Due to the wide variety and mix of terminals, which can be available on any one system, flow rate techniques may vary. Simply balancing on anemometer velocity readings alone, without continual reference to absolute values, can lead to poor results. Finally, recheck all terminals in terms of the percentage of design. If a section is shown to be out of balance, dampers can be reset, provided the flow in adjacent sections is not changed beyond the tolerance limits. This recheck will also serve as the record of the final state of the balance of the system. Lock all dampers in position. Alternatively, scribe the position of the damper arm and seal the operating screw. Finally, adjustable louvers and cones on terminal grilles and diffusers shall be set to positions as predetermined and specified by the designer. Summary The most important principle in proportional balancing is that damper adjustment must always start with the terminal next to the last in a group of terminals, or with the sub branch next to the last when balancing the duct system, and continue along the duct in the direction of the fan. Never adjust a damper, whether on a terminal or a branch or a sub branch, until all related dampers more remote from the fan have been set. Setting Plant Volumes It is common practice to reduce energy consumption by mixing return and fresh air flows whilst maintaining the minimum fresh air make up to meet ventilation requirements.



REEF TECH SERVICES

Modulating dampers are generally provided at fresh air inlet, exhaust discharge and recirculation. Limits to damper operation must be set to achieve the minimum fresh/recirculation airflows. Preferred method for measurement of airflow would be by duct pitot traverse of duct openings by vane anemometer may be possible. Approximate settings may only be possible, achieved by comparison of inlet and mixed air temperatures.

AIR SYSTEM VARIABLE AIR VOLUME

Initial Actions a) Establish the minimum static pressure required at the V.A.V. terminal inlet.

This should be obtainable from the unit’s supplier. The figure quoted is often in terms of a differential pressure. In this case either check a sample of units to establish the likely downstream resistance or approach the system designer for their best estimate.

b) Ensure that you have the facility to manually control the supply fan so that you can increase/decrease its duly as necessary.

It can usually be arranged for this to be available to the commissioning engineer, but in some needs the input of the control engineer. Make sure that all interested parties are aware of the need for CONTINUAL attendance if this is the case.

c) Ensure that you have the facility to manually drive the V.A.V. terminals between maximum and minimum

The current fashion for “intelligent” V.A.V. terminals often means that the controls engineer’s input is necessary for this function. Again make sure that everybody is aware of the need for continual attendance if this is the case.

d) Agree with the consultant engineer/designer on the number of terminals where individual pitot traverse volumes will be used to crosscheck calibration results.

This is usually 10-15%, providing that there is a means of obtaining airflow measurements from the terminal. e.g. voltage from hot wire type velocity sensors or velocity pressure from flow grids. There are still some types of terminals where the only means of proving the duly is to duct volumes by pitot transverse. It is also the case that very few, if any, systems have the necessary ductwork configuration for accurate volumes on all terminals.

e) Establish the degree of “diversity” built into the system and agree with the designer on the way in which the diversity is to applied.

Very few fans are sized to provide the duly necessary to satisfy all of the terminals at maximum volume. The shortfall (diversity) is usually taken care of by selling some terminals at minimum for the final fan test. This can be done by shutting down entire branches terminals or by closing down a small number of terminals on several branches. It is usually the case that the terminals nearest the fan are closed so as to prove the fan against the “worst case”, i.e. making it satisfy maximum demand at index terminals.

Testing the System

a) Pre-commissioning the system to ensure that all terminals and their controls are installed, all fire/smoke dampers are open, all access doors, etc., are fitted and that the ductwork is complete.

b) Having chosen a branch as a start point, ensure that all of the terminals on that branch are at maximum set-point. Measure the static pressure at the inlet to each terminal on the branch to establish which is the “index” terminal.

c) Adjust the supply fan duly so as to achieve a static pressure on the “index”

terminal in excess of the design minimum. Most V.A.V terminal suppliers advise that their equipment will operate as long as there is at least 125 pascals static pressure at the inlet. As a rule of thumb aim for 175-200 pascals for commissioning purposes.

d) Check each terminal on the branch at BOTH MINIMUM AND MAXIMUM SETPOINTS. Check the sample terminals by pitot transverse, again at maximum and minimum.

e) When all the terminals on the branch are correctly set at maximum and minimum measure the branch volume at maximum by pitot traverse and check the static pressure at each terminal inlet (any necessary re-calibration may have altered the location of the “index” terminal).

f) Repeat step 2-5 for all branches on the system.

g) When all the terminals on the system have been checked and the branch

volumes measured, apply the system diversity when and where necessary (as established in Initial Actions 5).

h) Measure the fan volume and carry out a full fan test. Record the static pressure

at each “index” terminals as established in testing the System 5. Note the setting of the fan’s manual duly control.

i) Record the results, issue the test sheets and demonstrate the results to the

client’s representative. Setting up the System for Automatic Control

This is usually done in conjunction with the controls engineers and may be included in the task, but is more usually arranged as an “extra to contract” – again check with applies. a) With the supply system in the same state as in Testing the System 8 and the

extract system at design duty, establish the static pressure at the static pressure sensor location(s) – as detailed by the controls engineers.



REEF TECH SERVICES

b) Establish the airflow velocity at the velocity sensors on both supply and extract systems.

c) Reduce the duty of both systems to a mid-point of their duly range (50-60% of

maximum design) by increasing the number of terminals set at minimum and reducing the fan duly to achieve the static pressure sensor (s) readings as in step 1 then reducing the extract duly to match.

d) Repeat step 2.

e) Reduce the duly of both systems to the minimum of their range (usually around

30% of maximum design).

f) Repeat step 2.

This gives the controls engineers enough information to set up the supply and extract fans to run in unison.

WATER SYSTEMS CONSTANT VOLUME

Pre Commissioning A. State of the System 1. General The installer should carry out inspections to ensure that,

a) All plant items are in accordance with the design specification. b) Correct installation procedures have been followed. c) Standards of installation and site cleanliness are acceptable. d) That the installation is fully complete and that all requisite checks have been

undertaken prior to system filling. e) The system cleanliness has been implemented by an adequate flushing and

cleaning process. In the absence of a Code of Practice on flushing, the procedures are recommended in Flushing and Cleaning of Water Systems BSRIA Technical Application Guide 1/89 should provide a guide to standards.

It is vital to the successful completion of the commissioning that the installer should be prepared to issue a cleanliness certificate to the commissioning engineer, if requested. This certificate must include the appropriate documents pertaining to any chemical cleaning. This certificate should be passed to the commissioning engineer before the system is commissioned. 2. Installer Detailed Checks In accordance with CIBSE Code W, the installer should undertake detailed checks to conform to his responsibilities regarding the state of the system. These checks are by requirement, more detailed than those that will subsequently be undertaken by the commissioning engineer, whose checks are made on the assumption of the satisfactory inspection by the installer. The commissioning engineer’s checks, are directly related to the commission-ability of the system and will not establish that the installation is installed to the requirements of the specification. Before Filling Particular checks to be undertaken by the installer should include but not be limited to ensuring that the following have been fulfilled:

a) All equipment and components are installed in accordance with the manufacturer’s instructions for the medium used (e.g. chilled, low, medium or high temperature hot water).



REEF TECH SERVICES

b) Pump and valve gland packing and special valve lubricants are compatible with any chemical to be used in the cleaning, flushing and corrosion inhibition of the system.

c) Permanent water connections have been made. d) Flow measurement devices have been installed in accordance with

manufacturers’ instructions. e) Probe pockets, pressure gauges, siphons and test points are installed. f) Manual and automatic air vents are fitted at high points as indicated in the

drawings and specifications, including continuous venting at low velocity sections.

g) Drain Valves and overflows of correct size are fitted. h) Connections to heater and cooler batteries and on the heat exchangers are

made correctly in relation to the design, air and water, flow direction. i) Control, double regulating and non-return valves are installed in accordance

with the flow direction arrows or other indications marked on the devices. j) Relief valves are installed to operate without restriction and in accordance

with manufacturer’s instructions. The outlets are piped away to suitable drain points.

k) Expansion devices are aligned and free from obstruction and are installed and fitted to manufacturer’s instructions including anchor points and rollers etc.

l) Strainers with the mesh, as specified, are installed in an isolated section. Changeover devices for duplex strainers are fitted. (Drain down cocks, are recommended for larger strainers). Access and lifting are adequately provided for.

m) All washers, tanks, nozzles and fittings are inspected for cleanliness. n) All valves and cocks are set in the operational position as given in the valve

schedule (e.g. open, closed). o) The cold feed or mains connection is located correctly. p) All pipe-work and fittings are adequately supported and anchored where

applicable in accordance with the specification. q) All test points are accessible to probes. r) All pipe-work is correctly identified and marked. s) Adequate access is maintained to all manual valve wheels and actuators on

automatically controlled valves. B. System, Filling and Venting (by the installer) Charge the system with water, treated (where specified) to the designers prepared plan. To ensure effective venting, fill slowly from the bottom upwards, thus forcing the air to high points for venting to atmosphere. Careful consideration should be given to the setting of valves and air vents before and during filling, to avoid airlocks and excessive spillage, particularly where the fill is treated. Take care not to exceed the working pressure of the system when filling from a high pressure source.



REEF TECH SERVICES

When the whole system is filled, disconnect the filling source, open the permanent supply connection and adjust the feed tank water levels. After static filling and venting the pumps should be operated for a period of about 1 hour and the venting repeated. Complete system venting may take up to a week to achieve. Warning: Do not attempt to fill the system via a pressurization set. It should only be used for final system top up. Frost Precautions: Where work is being carried out in cold weather it is essential that any equipment susceptible to frost damage be protected, by heating the system during working periods. Draining down should be avoided as damp internal surfaces are a primary cause of corrosion. C. Mechanical Checks (by the installer) 1. Pumps When the system is full of water the following should be checked:

a) The external parts of the pump are clean. b) The flow direction is correct. c) All components, bolts, fixings, etc. are secure and no distortion has taken

place on the base in tightening. d) The impeller is free to rotate. e) The level and plumb of pump and motor shaft and slide rails are correct.

Direct drive pumps require particular attention in this respect, with reference of manufacturers’ recommendations.

f) The anti-vibration mountings have correct deflection. g) The correct drive is fitted. h) The pipe-work imposes no strain at the pump connections. i) The pulleys and couplings are secure and their alignment is correct. j) The belts are tensioned and matched. k) Drive guards are securely fitted with proper access for tachometer readings

All requirements of the Health and Safety at Work Act regarding the safety of the engineer and other personnel must be strictly observed. 1. with all electrical supplies Isolated

Checks to ensure that:

a) Appliance and control circuits are locally isolated. b) There are no un-shrouded live components within the panels. c) The panels and switchgear are clean. d) The appliance and surrounding area are clean and dry. e) The transit packing has been removed from contractors and other equipment. f) There is no mechanical damage to switchgear. g) All the connections on bus – bars and wiring are tight. h) All the power and control wiring has been completed in detail in accordance

associated thermostatic controls have a suitable temperature range. p) All the cover plates are replaced.

2. with the Electrical Supply Available

a) Check that the correct provision has been made for local isolation of plant for

both electrical and mechanical safety. b) The declared voltage is available on all supply phases. c) Where motor power ratings are substantial, reduced voltage starting its used,

or if complex interlocks are involved, the control circuit logic and starter operation is tested before the motor is rotated. The supply should first be isolated by withdrawing two power fuses not associated with the control circuit, or by disconnection of cables. The control circuit should be actuated and the starter operation of all contactors, relays and interlocks checked. Finally, open the isolators reinstate the power fuses and close the isolators.



REEF TECH SERVICES

d) When small motors have direct on line starting and simple control circuits, the starter operation etc., should be checked when first starting the motor.

e) Never energize valve electrical actuators until mechanical checks have been completed.

Setting to Work A. With System Filled 1. Checks – Mechanical

ambient air or water temperature during the test period. d) A method of operating electrically controlled valve is available and that these

are set to normal operation mode. e) A method of operating pneumatically controlled valve is available and these

are set to normal operating mode. The pump suction or return valve is fully open.

f) The delivery valve only is closed on the standby pump unless non-return valves are fitted: the suction valve should be left open. (it is bad practice to leave any vessels full of water and completely isolated, as a temperature rise could cause an excessive pressure build up)

g) Pump casing is vented of air. h) The discharge or flow valve from the pump is closed by, say, 50% to limit the

initial start current. B. Initial Run

the electrical installer). d) The motor running current is balanced between phases. e) There is no overheating of the motor. f) On multi-speed motors, motor running currents are correct. g) The ventilation systems of air cooled motors are unimpeded.

2. First System Checks a) Avoid starting the motor repeatedly. (This prevents over stressing the fuses,

switchgear and motor).



REEF TECH SERVICES

b) Open the discharge valve gradually until the motor current reaches either the design value or the motor full load current, whichever is the lower.

c) Check the pump pressure developed, using the pump pressure gauges, against the system designed working pressure. (Where excessive pressure is developed at this stage, the pump should be shutdown and the cause should be investigated).

C. Running–in Period The pumps must be ‘run in’ in accordance with the manufacturers’ instructions. Do not leave pump unattended or allow them to run outside working hours. 1. Check that:

a) All bearings and motor temperatures remain within manufacturer’s specification.

b) After four hours running all strainers are inspected and cleaned. If they are excessively dirty then continue frequent inspection and cleaning.

D. Standby Pump The standby pump should be commissioned as above. E. Secondary Pump The secondary system (if any) should be isolated and the primary with system pressurization provided (where necessary) should be applied to assist in removing air from the system. Regulating Water Flow – Constant Volume System Basis of Balancing

Proportional balancing is used for constant volume system and the maximum flow method for variable volume systems without diversity. However, heat-balancing methods are sometimes necessary in final branch or terminal distribution. These involve temperature measurements. Warning Balancing a system requires the insertion of manometers with probes into pressure test points. In a charged system the water temperature must be below 60 Deg C when this is done. Under no circumstances must a MTHW or HTHW system be commissioned at operating temperature as serious injury may result. Any pressure or temperature measuring point must be preceded by a manually operated separate isolating device.



REEF TECH SERVICES

A. Preliminary Checks 1. Pump Shut Off Head Test To verify the operational performance of a pump it is necessary to check the measured performance against type test data provided by the manufacturer.

a) Connect a suitable differential pressure gauge across the suction and discharge pressure test points of the pump.

b) With the pump running, slowly close the discharge valve. Do not run in this condition for longer than 15 minutes or the time taken for the pump to overheat.

c) Determine the shut off head and check against the manufacturers’ data for zero flow.

d) Where the test results coincides with the manufacturers types test data proceed to (e). Where this is not the case, draw a curve parallel to that produced from the published data starting at the shut-off head pressure.

e) Open the discharge valve slowly to the full open position. f) Record the total head with the differential pressure gauge at full flow rate and

read the actual flow from the manufacturers data, or from corrected graph curve as appropriate.

g) If performance is inadequate refer to the installation contractor and designer. 2. Preliminary Flow Rate Check With all the valves fully open, measure and record the total actual flow rate and compare this with the total system design flow requirement. Where necessary, close the main regulation valve to provide a flow of approximately 110% design. B. Balancing The system is balanced on the basis of the ratio of actual flow rate to design flow rate. In any one branch the emitter units are regulated to the same proportion as the index (least favored) in that branch. Like wise, each branch on one riser and each riser on one header. This is achieved by measuring the pressure differential across flow measuring equipment and regulating the flow to design flow requirements by regulating valves. Repeated balancing may be required to bring actual flow rates within design tolerances. 1. Identification of least favored (index) and most favored circuits

a) Open all line circuit valves and close all bypass valves. b) Set automatic control valves manually to full circuit flow. c) Start pump (s) d) Using schematic drawing, measure flow rate and pressure differential at each

measuring station with manometer and record results. Check against design valves.



REEF TECH SERVICES

e) For each measuring station evaluate the percentage design flow rate DFR (%) = 100 fa/fd, where fa is the actual and fd the design flow rate.

f) Make certain that the primary flow measuring station at the pump is indicating DFR (%) = 100 – 110%. This ensures that there is enough flow to commission the system to the designer’s requirement within the set tolerance.

g) Starting at the pump, identify on the mains (headers, risers, etc.), that part of the system which is receiving the highest flow rate in terms of DFR (%). This will be the most favored circuit.

h) List the branches in descending order of DFR (%). That with the lowest is the least favored (index) circuit.

i) Balancing consists in the progressive closure of regulating valves starting with the most favored branch in the most favored circuit.

2. Balancing terminals, branches, risers, and headers by proportional flow

a) If DFR (%) for a branch is above 150% reduce the branch flow rate to give DFR (%) – 100%.

b) Double regulating valves should preferably not be set less than 25% open 75% closed.

c) Identify the least favored terminal, i.e. that with the lowest DFR (%).This is defined as the branch index terminal. In a typical distribution system this will be the last measuring point on the branch. If it is not, reduce the flow to the most remote terminal until f % is equal to that of the index terminal within the specified tolerance.

d) Adjust the regulating valve for the next terminal nearer the pump so that the DFR (%) values for this terminal and the most remote terminal are equal within the specified tolerance. Record the instruments readings, DFR (%) and valve settings for both terminals and lock the double regulating valves in their set positions.

e) Continue by adjusting the regulating valve for the next terminal nearer the pump until DFR (%) for this terminal is equal, within the specified tolerance, to that for either of the two terminals balanced in stage (d). This value will probably have altered from that recorded at stage (d) so it is essential to re measure the flow for every comparison of DFR (%) values. Record instrument readings, DFR (%) values and valve settings for both terminals.

f) Continue balancing the upstream as in stage (e) using the same reference terminal for comparison of the DFR (%) values until all terminals are balanced.

g) If it is found that the regulating valve for the index terminal has to be adjusted to achieve balance this indicates that the regulating valve on the most remote terminal was closed too far at stage ( c). In this case open the regulating valve for the next index terminal return to stage ( c), and follow the procedure through again.

h) Proceed to the next most favored branch on the riser and carry out terminal balancing as in stages (a) to (h).

i) For the complete riser each branch terminal is now in balance with the other terminals on the same branch. Branches now have to be balanced.



REEF TECH SERVICES

j) The procedure for balancing branches on a riser is identical to that for balancing terminals on a branch.

k) When several risers are fed from a header the same procedure should be used to balance the risers.

l) At this stage each riser, branch and header are proportionately balanced within the specified tolerances. Flow rates throughout the whole system will now retain the same proportional relationship for any setting of the main regulating valve.

m) Adjust the main regulating valve, to bring the total flow to the design flow within the specified tolerance. Record the instrument reading, the flow rate and the valve or speed setting and lock the valve or speed setting.

n) Check a sample of terminal, branch and riser flow rates as specified. o) Report to the designer any double regulating valves, which are less than 25

% open. p) Lock all the double regulating valves in the regulated position.

3. Secondary regulation of bypass circuit

a) On a straightforward bypass the regulating valve is brought into operation by opening the control valve to the by-pass operation.

b) The by-pass regulation valves should be adjusted to give the same flow rate through the bye-pass as the flow rate through the main bypassed circuit.

4. Secondary and Primary final regulation including injection circuits

a) In designs incorporating secondary pump systems including injection circuitry, the secondary circuits must be balanced with the primary circuit in operation but isolated from the secondary circuit.

b) With the secondary automatic control mixing three way valve in the full flow position, measure the primary flow rate and calculate the DFR (%) as in the secondary system.

c) Operate the secondary automatic control three-way mixing valve to the bypass position and regulate the bypass valve to give the same DFR (%) as in the secondary system.

Regulating Variable – Volume Systems Variable – volume systems fall into two categories. Small systems typically have thermostatic radiator valves and excess differential pressure relief valves. Large systems have zone differential pressure regulators and sometimes, variable speed pumping. The system is balanced on the basis of proportionality to ensure that under full design load, the correct mass flow rate occurs in each branch, riser and header. Balance of a variable – volume system requires the use of automatic flow control valves, operated by differential pressure, in each principal branch. Downstream of



REEF TECH SERVICES

the flow control valve proportional balancing is still required on all sub-circuits. An approximate balance can be inherent in the system design, e.g. in reverse return systems. Note: Suitable isolated pressure tappings should be located at the measuring positions for differential pressure control. This will enable the operation of the controller to be minimized. A. Small System These systems often have conventional thermostatic valves and flow – to – return differential pressure relief valves to ensure minimum flow. They are most conveniently balanced manually at low flow temperature by regulating to achieve approximately equal return connection temperatures. Thermostatic valves will automatically balanced at all part load conditions. It is important that the design ensures in minimum load (all thermostatic valves closed) the pump head does not exceed the maximum closing pressure of thermostatic valves. B. Larger Single Building Systems These are fitted with automatic differential pressure regulators (DPR) on sub – systems serving groups of terminals. DPR automatically balance the main pipe distribution upstream. 1. Differential Pressure Regulation

a) The DPR must be set correctly at the design pressure differential across the branch they serve.

b) The operation of each DPR must be checked and documented to ensure that it controls the differential pressure at low and high flow rates and with high and low upstream pressure differentials.

2. Sub – systems downstream of differential pressure regulators.

Each sub - system controlled by a differential pressure regulator required the

following commissioning procedure:

a) The correct operation of two-port control valves must be tested and recorded, under normal operation with all terminal control valves wide open.

b) Check and record the differential pressure across the sub-system. If this is below the design value due to system diversity it must be restored by temporarily valving off other sub-systems as necessary.

c) With the sub-circuit operating at its design differential pressure, measure and record the pressure drop across the index terminal and its control valve.

d) Measure and record the sub-circuit flow. Note that this may be higher than the design value if this was based on diversity, but the flow should not be throttled back to design value.



REEF TECH SERVICES

e) After dealing with all differential pressure regulated sub-circuits, any temporarily valve off to compensate for diversity should be recorded.

3. Main Pump Flow

The pump flow and operating head should be measured, recorded and plotted on the pump curve; note that these will differ from the pump design flow head for 100% load. The motor current and no-flow head should be recorded.

Note: This type of variable flow system is designed on the basis of diversity caused by the sum of all the terminal flows with control valves wide open, considerably exceeding, the total flow required to meet the maximum design load of the system. It is therefore not practicable to demonstrate the design flow and distribution without the design thermal load on the system. C. Regulation by temperature balance Where a system or part of a system consists of a number or relatively small terminal units, e.g. radiators, convectors, it will often be physically possible or economic to install a flow measuring device at every terminal unit. The technique of proportional balancing must therefore be adapted to the particular system. 1. Limitations The temperature balance method should be confined to low temperature hot water heating and chilled waters system, where an equal temperature difference is required through each terminal unit. 2. Procedure

a) Operate the system at a moderate flow temperature. This will be governed to some extent by the ambient temperature, but a minimum of 60C should be aimed for.

b) If the system is controlled by an outside compensator this should be adjusted to ensure that a constant flow temperature is maintained during the heat balance commissioning.

c) Regulate each terminal unit return valve until all returns register at equal temperature to the palm of the hand or by a contact thermometer.

General

When using the heat balance method a procedure similar to that recommended for balancing terminals fitted with flow measuring devices should be adopted, that is, regulate from the index back towards the pump. The heat balance and regulation on the terminals on any branch should be completed before the final regulation and flow measurement on that branch.



REEF TECH SERVICES

Note: This method is an approximation and will not achieve any significant level of accuracy. It is not appropriate to attempt to achieve a higher degree of accuracy, by use of accurate temperature measuring instruments. If accuracy is required the design must incorporate flow-measuring devices.

D. Flow rate measurement tolerances The tolerances as generally applied by the Company are set out in appendix B. These are those recommended in BSRIA Application Guide 1/79 Table V. In our experience these are appropriate for normal commissioning practice and should provide satisfactory system performance. The achievement of smaller tolerances would not have significant practical advantage, and is however achievable within the constraints of operating conditions.

ACOUSTIC COMMISSIONING TEST

Introduction

This document sets out a clearly defined test procedure for acoustic commissioning tests to establish room Noise Ratings due to the operation of the environmental engineering systems. Specification for Acoustic Test Equipment

a) All sound measurements shall be made with a precision sound measurement system conforming to the Type 1 requirements of BS 5979: 1981, or better.

b) This sound measurement system shall be complete with all the facilities required to enable to specified measurements to be obtained. As a minimum the sound measurement system shall include:

i) The facility to measure, using both “slow” and “fast” time weighting

characteristics. ii) The facility to measure, both “Linear” and “A” weighted sound levels over

the frequency range 20 Hz to 20 kHz. The accuracy of the “A” weighting filter network shall conform to the Type 1 requirements of BS5969: 1981, or better.

iii) The facility to measure, octave band filter sound. The frequency weighting characteristics of the octave filter set employed shall conform to the requirements of BS2475: 1964.

c) The sound measurement system shall be acoustically calibrated in absolute sensitivity at a reference frequency of 100 Hz. The calibration of the sound measurement system shall be performed immediately prior to, and immediately following each series of test measurements. Any variations in sensitivity of greater than 0.5 dB shall be recorded.

Measurement of System’s Noise in Internal Areas a) In order to minimize the effect of extraneous background noise, all sound

readings shall be taken with the test areas of the building evacuated, with the exception of essential test personnel. In addition every fort shall be taken to minimize external noise intrusion to the building.

b) All sound readings shall be taken under the two following conditions:

i) All plant and machinery running normally delivering the design conditions of ventilation, temperature and humidity (system + background noise).

ii) All plant and machinery switched off (background noise only).



REEF TECH SERVICES

c) The sound level in each octave frequency band from 63 Hz to 8000 Hz inclusive shall be recorded at each measurement location. In addition, the overall “A” weighted sound level shall also be recorded at each measurement location.

d) All sound readings shall be made with the sound measurements system set to either the “Slow” time weighting, or set to “Leq” (equivalent continuous) if this facility is available.

e) In each area of the building tested sound readings shall be taken at a minimum of 5 separate locations except where the room has a floor areas of less than 9 m2. The 5 measurement locations shall be chosen such that:

i) No measurement location shall be closer than 1.0 m from any surface,

including walls, floor, ceiling, desk, or partition. ii) No 2 measurement locations shall be closer than 1.0 m to each other.

iii) In offices a minimum of 2 measurement locations shall be at seated head height (1.2 m above floor level), and a minimum of 2 measurement locations shall be at standing head height (1.8 m above floor level). In other areas the measurement locations shall be chosen according to the expected normal position for occupants of the room.

iv) No measurement location shall be closer than 1.0 m to any ventilation system diffuser or grille.

Where the room has a floor area of between 4 m2 and 9 m2, two measurements shall be taken, and where the floor area is less than 4 m2 one measurement shall be taken. These measurements shall be taken either at seated head height (1.2 m above floor level) or standing height (1.8 m above floor level) depending on the expected normal position for occupants of the room.

f) The octave band sound readings in each area shall be averaged over all measurement locations in that area. The average sound level in each octave frequency band shall then be plotted on a standard octave band Noise Rating (NR) curve. Both the background noise levels and the system’s + background noise levels shall be plotted on the same NR curve.

g) Where the system’s + background noise level minus the background noise level lies between 3 dB and 9 dB in any octave frequency band, the effect of the background noise shall be accounted for in the evaluation system’s noise. The corrected system’s noise level shall be used to check for contractual deficiencies in that area.

h) Where the system’s + background noise level minus the background noise level is less than 3 dB, then an accurate evaluation of the system’s noise is not possible. In such cases in the event of contractual deficiency, the sound readings shall be deferred until the background noise decreases to at least 3 dB below the system’s + background noise (e.g. during the evening or night time periods).



REEF TECH SERVICES

i) The state of interior finish of that area during the noise measurements will affect the measured noise levels. Where internal areas are not fitted as per the occupied building, a correction factor ( C ) shall be added to the measured internal noise levels according to the equation

C = 10 log 10 (Tf / Tu) ………………………… (1) Tf is the measured or calculated reverberation time for the fully fitted out

internal area under consideration. Tu is the measured or calculated reverberation time for the internal area

under consideration at the time of the acoustic tests. The correction factor, C, shall be applied separately at each of the frequency bands measured. The correction factor shall not be applied in cases where the measured noise level is dominated by direct rather than reverberant noise.

Penetrations in Building Fabric

a) Where duct work passes through an acoustic barrier in the form of a wall or a floor the installer shall make an airtight seal to the duct work by densely packing mineral wool between the duct work and building fabric. A galvanized sheet metal sleeve of one gauge heavier sheet than the duct passing through the opening shall line the building fabric. The mineral wool shall be held in place by large galvanized steel angle sections riveted to the ductwork but not fixed to the building structure. The angle shall be pushed tight against the mineral wool packing and the building fabric with an unbroken seal of flexible mastic between to prevent the direct transmissions of duct borne vibration into the building structure. The angle shall overlap the hole by 10 mm all round. Exposed areas, if requested by the Owner, a plywood frame shall be provided as an alternative to the angle flange.

b) Where the pipe-work penetrates the building fabric pipes shall suitably sleeved

as in Clause ‘A’ above and sealed with a dense flexible mastic.

REEF TECH SERVICES

1. Introduction 1.1 Scope

The Commissioning of building services for Electrical Systems are addition to acceptance tests specified by equipment manufacturers and/or defined in the other Design Guidelines section. This practice specifies requirements and gives recommendations for electrical installation and equipments. Contractor should have commissioning plan to provide direction for the process during construction, providing resolution for issues such as scheduling, roles and responsibilities, lines of communication and reporting, approvals and coordination. This guideline defines the standard test that all electrical system and equipment must pass prior to final acceptance. Regulations : Regulation requires that every installation shall, during erection and on completion before being put into service, be inspected and tested to verify, so far is reasonably practicable, that the requirements of the regulation have been met. Reeftech guidance is divided into two sections, tests carried out before the electrical installation is energized and those carried out with an installation energized. The test specified by regulation should be carried out in the following sequence:

A. Tests before the supply is connected

Insulation Resistance Test

Polarity Test

Continuity Test

Earth Electrode Resistance

B. Tests with the electrical supply connected

Earth Fault Loop Impedance

Check of Phase Sequence

Functional Testing / RCD Test 1.2 Distribution, Intended use and Regulatory Considerations

Unless otherwise, authorized by Reeftech Services LLC., the distribution of this procedure is confined to companies forming apart by management of Reeftech. This procedure is intended for use in building commissioning for electrical system. If national and/or local regulations exist in which some of the requirements may be more stringent than this procedure, the contractor shall determine by careful scrutiny which of the requirements are the more stringent and which combination of



REEF TECH SERVICES

requirements will be acceptable as regards safety, environmental, economic and legal aspects. 1.3 Safety

The necessity of safety precautions during work on electrical equipment cannot be over-emphasized. Attention is therefore drawn to the safety committee on which safety codes and practices should be based. 1.4 Definition

The Contractor is the party which carries out all or part of the design, engineering, procurement, construction and management of a project or operation of a facility. The Principal may undertake all or part of the duties of the contractor The Manufacturer/Supplier/Vendor is the party which manufacturers/suppliers equipment and services to perform the duties by the contractor. The word shall indicates a requirement. The word should indicates a recommendation. Authorized Electrical Person – A competent person who is appointed by management to supervise to carry out specific work on electrical equipment and operations in power system. The appointment may include the authority to issue and cancel permits to work on electrical equipment. Electrical Pre-Commissioning – Those activities which are carried out after equipment erection and prior to energizing and performance checks. Pre-Commissioning is therefore concerned with the verification of the state of the equipment, quality of the installation work and compliance with requirements and codes. Electrical Commissioning – Putting into service a piece of equipment or system and demonstrating that the equipment or system is fit for the purpose for which it was intended. Inspection – Ascertaining the general running condition of a piece of equipment by sight, sound, smell and touch. (This may involve the opening of covers) Restoration – Carrying out work to maintain or restore the performance or functionality of equipment by: - The replenishment of consumed materials - The replacement of worn parts - The repair or replacement of damage parts 2. Commissioning Goals and Objectives Commissioning is a systematic process of ensuring that the electrical systems perform according to the design intent and the owner’s operational requirements. All equipments and systems should be installed according to manufacturer’s recommendations and the best practices and standards of the industry.



REEF TECH SERVICES

Commissioning will include documenting the design intent, followed by activities in the construction, acceptance and warranty phases of the project. The participation of the contractors in commissioning activities will follow the requirements defined in the specification. 2.1 Objectives - Document that equipment is installed and started as per standard - Document system performance with thorough functional performance testing and monitoring - Ensure that the operating personnel are adequately trained on the operation of the equipment - To verify proper functioning of the equipment / system after installation - To capture and record performance data of the whole installation as the baseline for future operation and maintenance 3. Procedures, Responsibility and Documentations 3.1 Procedure and Responsibilities Electrical installations and equipment engineered and/or erected by contractors and in general, any equipment which has been completed and is ready for operation, shall be subject to certain take-over procedures which shall have been agreed between the contractor and the principal well before the pre-commissioning stage. Furthermore, take-over procedure should state clearly the relevant responsibilities of contractor and principal. The organization and execution of Pre-Commissioning and Commissioning activities shall be the responsibility of contractor and/or commissioning management party. Unless otherwise agreed by the principal, complex electrical systems (e.g. HV/LH Switchgear, Generators, AVR’s, VSDS’s, UPS’s) shall be commissioned with the assistance of manufacturer. The steps required to connect an electrical system, prior to its initial energizing, to an existing electrical network, shall be jointly agreed by the authorized electrical person responsible for each electrical network. Where site conditions prevent full performance tests (e.g. Power Output, Temperature Rise), agreement should be reached between the principal and contractor on the need for such tests at a later date. If applicable, the principal should have internal procedure for equipment acceptance by engineering/construction department.



REEF TECH SERVICES

3.2 Documents The contractor and/or commissioning management party shall complete the inspection form from pre-commissioning and commissioning. Form is applicable to all equipment; subsequent forms shall be used as required. The contractor shall develop additional inspection forms for equipment not covered or not fully covered by commissioning management party. All deviations from requirements shall be documented on an exemption list which shall be presented to those responsible for the installation work for their agreement and action. 4. Testing Criteria and Commissioning Methods 4.1 Testing Criteria High potential tests shall perform at the AC or DC voltage unless specified otherwise herein. Performing more than one high potential test on any item shall authorized by the owner, contractor/consultant and/or principal. Dielectric absorption tests shall be performed with a 2,500 volt DC megger. Megger tests shall be performed at a DC voltage of 1,000 volts for 600 volts rated equipment, and at a DC voltage of 500 volts for 120-300 volt rated equipment. Continuity check shall be performed with a low DC meter, light or bell. The resistance to ground shall be measured using either the three point method or the fall-off potential method. Test instruments shall be calibrated to national standards to ensure the accuracy of tests. These calibration reports shall be made available when requested. Depending upon frequency of use, the instruments shall be calibrated at least every 12 months. 4.2 Visual Inspection Prior to manual operation and electrical testing, following needs to verify: - The equipment complies with the contract documents and the shop drawing submittal - The equipment is completely and properly installed according to the contract documents and the manufacturer’s instructions. - Adequate working space exists around the equipment to fully open doors and access panels, and to access all components that require for testing. - The equipment is free from damage and defects - Shipping blocks and restraints have been removed.



REEF TECH SERVICES

- The equipment has been aligned and lubricated if required - The ventilation louvers are open and unobstructed - Electrical connections have been tightened - Voltages, Phases and rotation have been identified - Terminations have been identified - Equipment labels have been installed - The equipment is ready to be electrically testing and commissioning 4.3 Insulation Testing Insulation test shall be carried out prior to the energizing of equipment and cable. The following 2 methods shall be used: - Insulation Resistance (IR) testing for motors, generators, transformers, LV Switchgear and all equipment other than those items susceptible to damage by over-voltage (e.g. Electronic Components) - High Voltage ac or dc testing for HV Switchgear and HV Cable 4.3.1 Insulation Resistance (IR) Test IR Testing shall be carried out by applying a dc voltage from an insulation tester at voltage level. For correct comparative interpretation of test data, Subsequent IR test should be carried out at the same voltage level as the initial test. The measured resistance value is also dependent on the temperature of the insulation. As a guide, the IR or windings reduces by approximately 50% for each 10°C rise in temperature. 4.3.2 High Voltage Test Before high-voltage test is executed, insulation resistance test shall be carried out. High Voltage test can be carried out by applying ac (power frequency), very low frequency (VLF), or dc voltage at a level above the operating voltage. There are distinct differences in the nature and practicality of this test. Whilst testing at power frequency is preferable, the ac test equipment must be capable of supplying the capacitive current requirement of the item under test. Thus physically large test equipment is frequently called for which is impractical for field commissioning use. For on-site commissioning, dc test equipment may be used.



REEF TECH SERVICES

High Voltage testing of electrical equipment, except LV cables, shall have been carried out at the Manufacturer’s work with ac at voltage levels in accordance with the relevant procedures or international standards. Repeated high voltage pressure test may introduce weak points in the insulation of windings, and therefore such tests shall not be applied at site to generators, motors and transformers. If, however, for special reasons these test are consider to be necessary, they shall be carried out only after consultation with the manufacturer. 4.4 Conductivity and Earth Resistance Test 4.4.1 Conductivity Test Conductivity test shall be carried out on Switchgear busbar connections and switchgear earth system joints in order to establish their tightness and condition. Conductivity testing shall be carried out with a low resistance test (e.g Ducter with a 20 A dc output) For identical connections the measured values shall not differ by more than 20% from each other. 4.4.2 Earth Resistance Test Confusing standards and conflicting opinions have plagued the field of grounding. One of the most important, but least understood considerations in designing and maintaining electrical systems is the grounding of all components. Low resistance earth grounding is essential for safety and protection. It is the basis for any facilities power quality assurance program. Effective earth grounding is essential for grounded ac and dc electrical equipment and distribution systems. Earth resistance test shall be carried out a regular program of testing to ensure effective grounding provides the level of safety required to protect personnel and equipment from shock and fire hazard. 4.5 Wiring and Terminal Checks Electrical wiring shall be check against the schematic diagrams. Factory tested assemblies such as switchgear should be require only sample checks. 4.6 Functional Test Functional test shall be carried out to demonstrate the correct operation of complete systems. Particular attention should be paid to equipment interfaces, where there is a greater likelihood of functional impairment.

Vibration Test Procedure



REEF TECH SERVICES

Section A : Vibration Test Procedure

a. Definitions and Terms for Report Interpretation: Vibration amplitudes are expressed in terms of velocity decibles, abbreviated as VdB. The zero reference for VdB is 1 x 10 E-8 (0.000,000,01) meters per second rms. For comparison, a vibration velocity amplitude of 120 VdB is equivalent to 10 millimeters per second rms, and 125 VdB is equivalent to 1 inch per second peak. When using decibel amplitude scales, a difference of 6 dB between any two readings means that there is a 2:1 ratio between the two vibration levels; a difference of 20 dB between any two readings means that there is a 10:1 ratio between the two vibration levels. If you prefer to use units of inches per second, a conversion table from VdB inches per second peak is included below for your convenience.

Statistically, that means that 20 out of 24 identical machines will not exceed the level, or roughly 16 percent will exceed the “alarm”. Level and will be subject to more detailed engineering analysis. In most cases, vibration frequencies are identified as multiples (orders) of the shaft rotating speed of the machine component being analyzed.
