3 ARV Water cooled water chillers, semi-hermetic screw compressors, brazed plate or shell and tube exchangers, refrigerant gas R134a. Heat pump by hydronic circuit inversion, condenserless unit. One compressor for each circuit, with capacity steps 25/50/75/100%. EER 4.7; ESEER 6. Units designed for commercial or industrial applications, where required a good protection from freezing. Only for indoor installation. Cooling capacity from 251 up to 1102 kw Heating capacity from 282 up to 1233 kw R134a refrigerant 3
4 Available versions CHILLER: basic version to be associate, for example, with a separate dry-cooler or using ground water and/or with an hydronic hot user plant. HEAT PUMP: with inversion on hydronic circuit. - This version is identical to chiller unit, but the control is based on hot water temperature, when switched to heat pump mode. - This unit need to invert the user water flow from the evaporator (chiller mode) to the condenser (heat pump mode) so to have hot water for the user. - The inversion on hydronic circuit shall be done by external devices not supplied with the unit. CONDENSERLESS UNITS: these units are supplied without integrated condenser; they can be connected with an outdoor air-cooled condenser; optimal solution for very cold climate can easily solve the problem to protect against the freezing, the circuits with water inside. PARTIAL HEAT RECOVERY (desuperheater): an heat exchanger is inserted along the compressors discharge line before the condenser, it s able to desuperheat the hot gas and produces hot water up to 55 C. The amount of recovered energy is around the 20% of the cooling energy production. CLIENT: units with special equipment or devices on request. 4
5 Features Structure of electro-galvanized and painted steel sheet Air condensed water chiller with screw compressors. Ecological refrigerant R134a This refrigerant R134a with zero ozone depletion potential (ODP=0) together with a very low value for the global warming effective potential is the best choice for circuits with semi-hermetic screw compressors. Making maximum their energy performance. R134a 5
6 One semi-hermetic screw compressor on each refrigerant gas circuit, with 4 capacity steps for maximum cooling water temperature precision at partial loads. The choice of screw compressor allows you to have low vibration and noise emissions. Reliability is high thanks to the reduced number of moving parts and to the high capacity of the compressor to adapt to many different conditions. Due to its construction, semi-hermetic screw compressors has reduced vibration compared with piston compressors. The 4 cooling capacity steps allows the compressor to follow very well the variation of the user load, with a very good control of chilled water temperature. The design of the compressors is optimized for the project working range, so it s possible to reach very high performaces for energy saving. It s possible to equip the compressor with the stepless capacity control, very useful for sistems that need very accurate cooling capacity control. To have the maximum EER performance, it s necessary declare the water temperature working range, to select the best compressor configuration. Screw compressor Condensers Depending on the number of circuits of the unit, they can be brazed plates or shell and tube heat exchangers. In both solutions the condensers are abundantly dimensioned, to allow very low condensing temperature, for maximize EER performance. Brazed plates condensers made in stainless steel specifically designed for R134a. In addition to a very high mechanical resistance, due to the use of stainless steel, they have high corrosion resistance and very low content of refrigerant gas. Shell and tube condensers specifically designed for R134a, the exchangers are manufactured for the maximum reliability. The materials are: carbon steel: header, tube sheet, shell, refrigerant and water connections; copper: heat exchange tubes with inner finned surface; bonded steel bolts fit for the temperatures generated during use; Brazed plate condenser Shell and tube condenser 6
7 Evaporators Depending on the number of circuits of the unit, they can be brazed plates or shell and tube heat exchangers. In both solutions the evaporators are abundantly dimensioned, to allow very low condensing temperature, for maximize EER performance. Brazed plates evaporators specifically designed for R134a, made in stainless steel. In addition to a very high mechanical resistance, due to the use of stainless steel, they have high corrosion resistance. These evaporators work in perfect countercurrent and allow to have very high evaporation temperature for maximize EER performance. An integrated distributor guarantees a perfect equalization of the refrigerant gas flow inside each plate heat exchanger, for maximum performances. Shell and tube evaporators specifically designed for R134a, the tube bundle is composed of a series of premodelled U-shaped tubes enabling the free expansion of them independently from the shell. The buffles are positioned so as to enable an optimal flow rate compatible with the pressure drop which may occur. The water connections are provided with flexible joints for the following advantage: easy and lowcost installation (assembly and disassembly); adaptability in case of shifts, dilatation and other movements; absorption of vibrations. These evaporators work in perfect countercurrent, and allow to have very high evaporation temperature for maximize EER performance. The materials are: carbon steel: header, tube sheet, shell, refrigerant and water connections; copper: heat exchange tubes with inner finned surface; bonded steel bolts fit for the temperatures generated during use; Brazed plate evaporator Shell and tube evaporator 7
8 Thermostatic expansion valves As standard all chillers are equipped with thermostatic expansion valves to ensure a return of dry gas to the compressor. Electronic expansion valves on request by request the unit can be equipped with electronic expansion valves. These valves, via an electronic driver, a temperature sensor and a pressure transmitter, are able to provide a more precise value of superheating. The graph below shows the effect of switching between the operation of a chiller with a TEV (thermostatic expansion valve) to an EEV (electronic expansion valve). The lowering of the average superheat value, the stability of the value itself and the operating pressure are clearly evident. Carel controllers and Electronic Expansion Valve 8
9 Electronic regulation by a microprocessor card for the management and control of all functional parameters. The controls normally used are parametric products of Carel. For all chillers, the used control is Carel pco with a semi graphic terminal. The available languages are English, French, German, Italian and Spanish. The functions controlled are: a. regulation on inlet water temperature, with the alternative possibility of adjusting the output water temperature; b. management of cooling capacity with step capacity control of the compressors, depending on the request of the hydronic circuit; the control is such that the number of operating hours per year of each compressor is the same for everyone; c. prevent high pressure - this function allows you to reduce the cooling capacity of the compressor when the condensing pressure rises too much; d. condensing pressure control by a 0..10V signal, able to manage a modulating valve or a fan speed controller (in case of condenserless unit); e. antifreeze heaters (when installed) - a set of heaters protect the evaporator circuits containing water when their temperature drops below the safety threshold; f. circulation pump control; g. flow switch; h. water temperature set point variable by external contact; i. communication with supervisory systems; j. general circuit alarm; k. anti freeze alarm. pco control semigraphic terminal 9
10 Hydronic circuit The unit is normally equipped with Victaulic flexible couplings complete with clamps and solder terminal tubes. On request the unit can be completed with: flow switch, antifreeze heater for evaporator, water safety valve, water filter. Note: water filters and flow switch are supplied separately from the unit, to be installed by the user. Hydronic circuit Connection diagram of heat pump by hydronic circuit inversion 10
