3. General technical regulations

3.1 Heat exchange stationsThese are facilities serving for the connection of outlet facility to a primary heat net. Exchange station must be constructed sothat necessary heat output is provided for the supplying object or a group of objects. It can be designed as having dependentor independent pressure. From the construction point of view it must be designed as a space separated from other areas byminimum fencing, ideally by concrete divisions or as a separate object. The station must be equipped with an opening formanipulation with technological facility for repair needs and maintenance (size of the opening should be designed dependingon the size of the biggest component used).Heating machinery stations must always be accessible for servicing and maintenance workers, if possible by a separateentrance from outsider. In the cases where this cannot be securred solution must be consulted and approved by the ŠE-ESdepartment already in the project stage.

3.1.1 Realization and dimensionsEvery exchange station must be placed in separate space with sufficient space so that pipage, technological facilities(exchangers, pumps, etc.) can be clearly placed here as well as controlling, regulativ and measuring facilities. If this istechnically feasible also a hot water preparing facility must be placed into the space of the exchange station.

Technical parameters of primary heating system:

WINTER SUMMERinlet branch temperature 130 °C 80 °Creturn branch temperature 70 °C 60 °C

disposal pressure 300 kPa 175 kPa



/21

Size of the pressure disposal is dependent on the placing of the exchange station in dependence on the heat generatingstation. For the exchange station proposal the supplier (projektant) must request connection conditions for the currentŠKODA AUTO net (ŠE-ES).For drawing the dimensions fot he exchange station the supplier must submit a verified pressure diagram of the ne torrequest it at ŠKODA AUTO (ŠE-ES).Supplement 1 includes temperature diagram of the hot water system – dependence temperatures of the outlet water fromthe heating source on the outside temperature.

3.1.2 Design componentsThe inlet branch of hot water into the exchange station must be fitted with a closing fitting, inlet filter, emergency endingwith electric drive and a straight working regulátor of pressure difference (the sekond option is recommended), straightpointing temperature and a manometer.The return branch must be fitted with a straight pointing thermometer, a manometer and a finishing fitting.

Emergency shutdown valve with a double function (regulation fitting) secures:- regulation of constant difference pressure at the entrance into the station (this function is performed by a straight

working fitting in the second option)- closing of the hot water inlet into the station if the inner temperature of the station set is exceeded or if the

exchange station is flooded



/21

Distributor and collector (hereafter referred to as D+C)Distributor and collector may be constructed as integrated or separated with one reserve cap. It must be fitted with an outletfitting min.DN50 and a closing fitting at the inlet to D and outlet from C. D+C must be fitted with a straight pointing differencemanometer and thermometer.

The individual branches from D must be fitted with closing and outlet fittings and with venting in the highest spot.The individual return branches to S must be fitted with a balancing, closing and outlet fitting and straight pointingthermometers.

Heat exchangersDesk exchangers with a higher value of heat transfer coefficient (U).They may be welded or possible to disassembler (disassembling desk exchangers are preferred for process media – spas,chemicals, etc.). Exchangers to be fitted with closing fittings for easy installation and uninstallation.

Desk exchangers to be connected into the system as instructed by the exchanger manufacturer.For regulation of heat output a two-way regulation valve is preferred.

3.2 Heating systems

3.2.1 General principlesHeating systems must be projected and realized so that all necessary functions are securred, i.e. heating water temperatures,heat output requested in relation to the required temperature in the working space and outsider temperature as well as otherrequirements involving in particular easy servicing and maintenance of the whole system.

Using a heating system1. water2. hot-air3. electric4. gas

Water system parameters:

temperature operational pressure nominal pressure1. hot water 130°/ 70°C 1,3 MPa/ 1,0 MPa PN 162. hot water do 100°C PN6, PN10

When designing heating technology for new projects of painting technology the temperature of the inlet heating water is tobe 90°C at max.

Handover stations must be visualized in a superordinate controlling system. Each connection must be approved by the systemadministrator (SE-ES).

From the construction viewpoint two-pipe systems are preferred. Approval of ŠE-ES is needed if one or several pipe systemsare to be used. Heat power to be determined in keeping with ČSN 060210 based on heat losos of the heated space with innercalculation temperature of 18°C for work spaces in shops with permanent residence (according to the Collective agreement)and minimally 20°C for adiministration buildings.At non-mixed distribution of heating water all appliances, handover stations, etc. must be designed for the temperaturerange required 130/70° in heating season or 80/60°C in summer season. It is necessary to use the return temperature toachieve the calculated 70°C as required (or 60°C in summer) because of proper cooling of the return water.

3.2.2 Construction componentsHeating bodiesDepending on the type of heating space and pressure and temperature parameters of the heating water it is necessary to useall types of heating bodies – sectional, desk, pipe or convectors.With hot water systems it is necessary to submit authorization of use in temperatures rating to 130°C and pressure of PN 16.Connection of the bodies to the pipe net must be realized so that the body may be replaced without the necessity to bleedthe pipe system (use a radiator connector). The heating body must always be fitted with a closing fitting or apermanent/replacable visually controlled setting of regulation (TRV) or a closing fitting (ball valve) if the regulation is central.

Pipelines, fittings and pumpsPipelines, fittings and pumps must be designed and supplied according to ITS 1.14. Pipage hot water systems must be fittedwith air ventilation containers involving a ventilation pipage in the highest possible spot descending by a maximum of 1 mabove the floor and in the lowest spot with water drain valves. Venting of hot water systems may be performed usingautomatic bleeding valves which must be installed with regard to the risk of bleeding (e.g. must not be installed above lowviewpoints. Dross from these valves must be warped into spaces where venting/drossing can be performed without the riskof damaging adjacent areas and facilities. Especially in office spaces placement of venting or bleeding must be consulted withŠE-ES department.

Size of the draining fitting near pipelines:< DN25 in the pipeline dimensionDN25 – DN80 in dimension DN25≥ DN100 in dimension DN50



/21

Safety systemsIn keeping with ČSN 06 0830 safety systems of secondary circuits of heating systems should be designed which integrates asafety and expansit facility. Expansion facility must be used to level the changes of water ductility and maintenance ofpressure level of secondary circuit of the heating system in the limits prescribed.All pressure independent heating systems must be equipped with automatic refill and bleeding of water into the secondarycircuit. Water from the return branch of the primary hot water system can be used by leading it through solenoid and returnvalve.In line with ČSN 06 0310 tests of the safety facility to be conducted as required and a protocol of the test to be drawn.

Hot water systemsThese facilities are used at ŠKODA AUTO to heat spaces as purely circulation units or with an inlet of fresh ventilation air.Preferrably they are used for heating spaces with lower demands on the quality of the inlet air, mainly for hoting entrances,passages and covered approaches. In these cases it is necessary to align the operation of the system’s ventilátor with endswitches of the door when the unit is switched on while the door is open and switched off while the door is closed. Pipeconnection of the unit exchanger to heating water must be conducted so that the inlet pipeline includes manual closingfitting, closing fitting with electric drive (a ball cock or a valve with a drive can be placed here) and the manual return pipelineincludes a balancing fitting (fulfills also the closing function). Outlet must be located in the lowest possible spot. Closing fittingwith electric drive must be joined with the unit’s operation. It is going to be open if the ventilator operates and closed if it isswitched off. To keep the temperature of the inlet heating water into the unit’s exchanger a small regulation fitting must beplaced in front of the unit (only in cases when the appliance is connected with a long connector or it is the last connected heatuser at the end of the branch) for which a minimal flow of heating water is set so that uncooled water is immediately availablewhen the unit is switched on.

Gas and electric systemsIn the attempt to use the potential of hot water generation in the heating cycle to the maximum use of gas or electric systemsto heat the spaces is going to be conditioned only by the technical-economic calculation proving its efficiency as against useof hot water.These types of systems must not be installed without the approval from ŠE-ES.

3.2.3 Heat output regulationRegulation of heat output of secondary circuits must always be solved qualitatively depending on the outdoor temperature,i.e. by regulation of the output temperature of the heating water from the exchange station with the possibility to regulace itin the working space (TRV).Requirements on the control systems are given in ITS 5.13.

3.3 Preparation of hot water (HW)

3.3.1 General principesWhere this is possible from the viewpoint of disposition arrangement and where this is more economical (range and divisionof distributions), preparation of HW for common transfer station with heating systems. In order to use the secondary space tothe maximum preparation of hot water can be solved simultaneously with the preparation of heating water into secondarycircuit using desk exhchangers, so called blocking arrangement. Where the HW preparation cannot be located into commontransfer station, it must be located in an autonomous space separated from ordinary working space at least with a fence.

3.3.2 Drawing dimensions of hot water preparation

To facilitace heating of hot water desk exchangers are to be used in combination with accumulation container. In smallerfacilities with a constant hot water usage in time the accumulation container does not need to be used.

Hot water with the following parameters is a primary medium for hot water heating:

WATER SUMMERTemperatures conduct branch 130 °C 80 °C

return branch 70 °C 60 °C

Pressure disposition pressure 300 kPa 175 kPa

If the use of hot water is not realized in the transfer station it is necessary to request from ŠE-ES and verify throughmeasurement the pressure parameters in the spot of connection of hot water (e.g. inside an object).HW heating must always be designed as indirect (HW is permanently separated from the heating substance).HW consumption to be proposed in keeping with ČSN 06 0320, with the HW temperature ranging between 50 - 55°C.Facility for HW heating must be equipped with automatic regulation ensuring the required heating of HW and at the sametime preventing its excessive heating.

3.3.3 Construction componentsInlet and return branchA manual closing fitting, inlet filter and regulation fitting with electric drive must be placed at the inlet branch of the primarycycle. Return branch is fitted with a manual closing fitting. In the case that HW heating is located in front of the transferstation it is possible to leave out the installation of the filter and possibly also of the closing fitting (if these are bainginstalled).Depending on the size of differential pressure before the exchanger on the primary side it is necessary to decide on the typeof mixing using a three-way fitting or a two-way fitting with a fixed shortage based on the above stated principles.Regulation fittings will involve fast drives and the regulators will be of the PID type.Pump on the primary side must be in permanent operation. Charging pump on the secondary side of the exchanger will also beoperated permanently.

Heat exchangersDesk exchangers with a higher value of the heat passagge coefficient U. Soldered or dismountable version may be used. Pipeexchangers can also be used in combination with accumulation container. If galvanized pipes are used on the side of the heatexchanger, copper inlays must not be used in the exchangers due to the possibility of electrolytic corrosion.Desk exchangers must be connected in the water heating systém according to the exchanger’s manufacturer instructions.Desk exchangers for hot water heating must be equipped with special desks that ensure higher speed of water and thusreduce the risk of clogging.



/21

Types of desks for the individual manufacturers of desk exchangers:

Alfa Laval type EOTTO type HCetethem type T 415 (421)GEA type H

It is preferrable that such connection is used on the primary as well as secondary side that a constant flow through theexchanger with a temperature of medium up to 65°C max. (three-way mixing valve and a pump, regulation valve and by-passwith a pump, etc.)All types of valves must be fitted with closing fittings for easy uninstallation and installation.The exchanger dimensions must be planned so that the whole content of the accumulating tank can be heated within a halfof the working shift lapses, i.e. in four hours.

HW accumulating tankWhere direct heating of HW cannot be used due to the fluctuation of the outlet direct heating, accumulating tank must beinstalled. The tank can be constructed vertically or horizontally depending on the disposition of the given space. Storageaccummulation tank must be fitted with a direct showing thermometer and manometer with closing fittings at the inlet andoutlet. Tanks must be provided with an inspection opening.

With water heating storage tanks and hot water storage tanks of 600 l and more, automatic sludging mechanism (automaticopening of sludging fitting) must be installed. A bypass with a manually closed fitting must be installed around the automaticsludging fitting.Sludging opening in tanks of 400-1000l must be equipped with sludging fitting of min.DN25, with tanks larger than 1000lsludging fitting DN50 must be used.

For cases of hot water shutdown in the primary system accumulation tanks must be equipped with electric heating of HW.Dimensions of the electric heating must be adapted so that at least a half of the overall capacity of the tank is heated withineight hours to achieve the required parameters. This condition also implies the necessity to divide the overall requiredcapacity of HW into several tanks.

HW circulationWith all types of HW preparing systems necessary circultion of HW must be planned.Exception is given to small stations with small number of outlets. In such cases and in cases bordering between bothpossibilities ŠKODA AUTO’s statement (ŠE-ES) must be requested.The pump dimensions must be planned to exchange the overall volume of HW in the distribution circuits about four or fivetimes per hour.

Pipelines, fittings and pumpsPipelines, fittings and pumps must be projected and delivered as per ITS 1.14.For HW conducts steel pipelines without inside surface finishing by galvanization may not be used. The reason are corrosionwater polluting products.All screw joints must be fitted with screws to enable mechanical dismounting.

3.3.4 Typical scheme of connection of HW heatingConnection scheme of HW heating must be based on the need to secure certain amount of HW in a given time.The function scheme design of the transfer station must always be consulted with ŠE-ES.
