HFC R134a

High effi ciency chiller, water sourceIndoor unit for the production of chilled water featuring cen-trifugal compressors oil-free, with R134a, electronic regulation valve, shell and tube condenser and shell and tube f ooded evaporator. Base and supporting structure and panels are of galvanized epoxy powder coated steel with increased thickness. Flexible and reliable unit; it easily adapts itself to different thermal load conditions thanks to the precise thermoregulation together with the use of inverter technology. The compressor is radically innovative: magnetic bearings and digital rotor speed control allow partial load eff ciency levels to be reached that were hither to impossible.

Unit supplied with refrigerant charge and factory tested. On-site installation therefore just involves making connections to the mains power and water supplied.

2.1 Standard unit composition Structure Frame comprising supporting elements in polyester-painted thick hot galvanised sheet steel. The self supporting frame is designed to ensure maximum ease of access during servicing and maintenance operations.

Compressors Two stage, variable speed, centrifugal compressor with alu-minium impellers, designed requiring no oil for lubri f cation. Compressor constructed with cast aluminium casing and high strength thermoplastic electronics enclosures. Compressor provided with radial and axial magnetic bearings to levitate the shaft thereby eliminating metal to metal contact, and thus eliminating friction and the need for oil. Each bearing position is sensed by position sensors to provide real-time repositioning of the rotor shaft, controlled by the on-board digital electronics. Compressor speed is reduced as condensing temperature and/or heat load reduces, optimizing energy performance through the entire range. Continuous modulation is possible thanks to the integrated in-verter. Signals from the compressor controller determine the inverter output frequency, voltage and phase, thereby regulat-ing the motor speed. In case of power failure, the compressor is capable of allowing for a normal de-levitation and shutdown. Inlet Guide Vanes is built-in to further trim the compressor ca-pacity in conjunction with the variable-speed control, to opti-mize compressor performance at low loads. The compressor is provided with a direct drive, high eff ciency, permanent-magnet synchronous motor powered by pulse-width modulating (PWM) voltage supply. Motor cooling is by liquid refrigerant injection. A non-return valve on the discharge port of the compressor is installed to protect against backf ow of refrigerant during coast-down; a thermal protection protects against over-currents while a soft-charge device reduces in-rush starting current under 2 amps.

Heat exchanger on plant side Heat exchanger, with a function of evaporator, shell and tubes, f ooded type, with water f owing inside and refrigerant f owing outside the pipes. The steel shell is insulated with a foamed polyethylene closed-cell mat of 10 mm thickness and a thermal conductivity of 0,033 W/mK at 0°C to avoid condensation on its surface. The copper tubes are internally and externally grooved to improve heat exchange. A drop’s separator is integrated in the evaporator to protect the compressor against the possibility of liquid’s suction. A differential pressure switch is already f t-ted in order to monitor the water f ow while the unit is working,

avoiding the risk of ice generation. The heat exchanger comply with PED standards, concerning to operating pressure.

Heat exchanger on source side Heat exchanger, with a function of condenser, shell and tubes, f ooded type, with water f owing inside and refrigerant f owing outside the pipes. Only for the units in function /H (heat pump reversible on hydraulic side), the steel shell is insulated with a foamed polyethylene closed-cell mat of 10 mm thickness and a thermal conductivity of 0,033 W/mK at 0°C to avoid con-densation on its surface. The copper tubes are internally and externally grooved to improve heat exchange. Heads can be removed to inspect the tubes. Under request it’ s possible to have a 4-steps heat exchanger (water side) for application with low-medium temperature sources (for example underground water). The heat exchanger comply with PED standards, con-cerning to operating pressure.

Refrigerant circuit Unit designed with a single refrigerant circuit in order to op-timize the heat exchange’ s process, especially in part load mode, without any risk in the proper management of oil which is, in this series, completely absent. Standard components of the refrigerant circuits are, in addition to the previous one: - electronic expansion valve - dedicated sensor level on condenser side - high and low pressure safety valve with visualization of the

pressure’s level and the rotational speed directly from the controller’s interface

- compressor’s discharge and suction shutoff valve - liquid line shut-off valve - drier f lter with replaceable cartridge - refrigerant line sight glass with humidity indicator - high pressure transducer.

The controller is suitable for the management of 2- or 4-pipe systems, with regulation on one water circuit, for chiller- or heat pump units and relevant mode change-over , and also with regulation on two circuits, with independent set-points and parameters, thus exploiting the simultaneous supply of chilled- and hot water. The controller manages up to 8 units, with activation logic focu-sed at the balancing of operation times and at the achievement of the highest energy eff ciency. It is possible to def ne conditions of dynamic stand-by and priority as regards the units’ activation. It is also feasible the rotation among the system’s units, also in cases of constant load. The alarm management is featured, with plain text descriptions and possible notif cation to remote recipients. Two relay outputs are available, associated to unit- and device alarms. The user interface allows a safe and easy use, thanks to its touch-screen display, back-lit 8.4” type. The multi-level menu features the language selection and diffe-rentiated access prof les(user and maintenance).The circuit tem-peratures and the status of both system- and unit- operation are displayed, via one overview page plus detailed pages. The regu-lation can be based on proportional- or proportional+integral lo-gics, or also on a dead-band algorithm with dynamic adjustment, with relevant temperature inputs managed by the device. Features as set-point offset, also referred to the outdoor tem-perature, and demand limit are included, with relevant analog inputs. The device is integrated in the best way with the units, preventing

simultaneous activations or resources and optimizing eff ciency, overall inrush current values and also operation of water pumps possibly associated to the units. The WebManager option allows the access to the device and its settings, via any computer , with direct- or LAN-based con-nection, therefore also via internet resources; this is associated to the availability of historical charts for the main operating variables. The “Variable Primary Flow” option represents a unique regula-tion dedicated to hydronic systems with variable water f ow. This represents a crucial contribution to the reduction of the costs related to the hydraulic plant and its operation.It is available as option the interface with the Demetra metering device: thus it is possible to acquire and log the values of the system units’ electric consumption, together with their operating status; this allows therefore to analyze the system’ s operating performances throughout time, in terms of both absorbed energy and cooling / heating capacities, consistently with the implementation of enhanced energy management policies for the building.

11. VARIABLE FLOW HYDRONIC GROUP (optional)

11.1 VPF systems: plants designed with a single variable fl ow hydraulic circuit

The energy consumption associated with fl uid circulation wei-ghs heavily on the total operating costs of a large Installation, especially when the units work at part load, and even more, when they are in stand-by. Under these conditions, although the power absorbed by the compressors and fans is reduced, the power consumed for water circulation remains high.The TECS2-W permits reduction in system power consumption using pumps with continuous ow control by inverter. Energy sa-vings are considerable and immediately evident, to the extent that an Δx reduction of the ow of water to be delivered to the sy-stem amounts to a proportional reduction of (Δx)3 in the power absorbed. High or low head accessory pumps controlled by in-verter can be installed. In the most advanced systems (see the simplifi ed model shown in the diagram below), these become the pumps for the entire hydraulic circuit, and this eliminates the need to detach the primary from the secondary circuit for the

purpose of water circulation throughout the entire system. Previously this was the only choice possible in traditional sy-stems, and imposed primarily by the need for the chiller to work with constant water fl ows through the evaporator. Now, thanks to the TECS units, designers need no longer worry about this limitation. The unit has been designed to work at maximum efi ciency even with variable fl ows to the evaporator and independently adjust itself in order to keep the outlet water temperature constantly at the set-point entered by the user. This simplifi es the design and realisation of variable fl ow systems and offers advantages in terms of both reductions in consumption and hydraulic circuit sizing. In short, in addition to energy saving and consequently lower running costs, this innovative solution enables simplifi cation in design that ensures substantial savings in initial investment costs.

The “system VPF” option comprises: - extensions on the controller to read the system’s pressure

transducer signals (4-20 mA) and the consequent manage-ment of pumps and bypass valve (0-10 V signal)

- additional pressure transducer as extra safety device.Pressure transducer, pumps and bypass valve at client respon-sability.

Working logic of “smart” plant with an only one variable primary fl ow circuit

Traditional plant “Smart” plant

It is necessary to have a “decuple” system, which uses constant water fl ow through each chiller evaporator and variable water fl ow through each cooling coil to satisfy space loads. As each two-way valve adjusts the ow of chilled water through the coil to satisfy the existing load, the distribution pump responds by regulating the amount of chilled water delivered. Water fl ows through the bypass in either direction as needed to balance the system.

There is an only one variable primary fl ow circuit, which vari-es water fl ow throughout the entire system – that is, through the evaporator of the operating chiller as well as through the cooling coils. Two-way control valves and a bypass valve are required; the bypass valve ensures that the amount of the fl ow that returns to the operating chiller(s) never falls below the mi-nimum limit.

11.2 VPF.D systems: plants designed for variable fl ow, de-coupled, primary and secondary circuits

Even in that cases in which is not possible to work with a sin-gle variable primary fl ow circuit, or in that situations in which is preferible to mantain decoupled the primary circuit (to the units) and the secondary circuit (to the plants), it’s possible the prima-ry fl ow on pumps controlled by the unit.The energy savings are lower than the solution with a unique VPF system, but still important expecially when the units are in stand-by where it’s possible to reduce the waterfl ow through the unit up to 50%.The VPF.D systems can be easily adopted in retrofi t applica-tion, where the chiller is supposed to be replaced but the plant isn’t.

The regulation is up to the unit’s controller, detecting the delta temperature at the primary heat exchanger: when the building’s load decreases, waterfl ow is reduced in order to mantain a fi -xed delta T between the exchanger’s inlet and outlet. The VPF.D system by Climaveneta assures even the waterfl ow balancing between primary and secondary circuit, in order to avoid the fl ow inversion in the decoupling pipe.
