5 Features R40A Chiller Hitachi was the first in the world to successfully introduce R40A refrigerant in all its products, including air conditioners, package air conditioners and now the SCREW CHILLER. Innovative technology is applied in the design and development of the compressor, refrigerant cycle, and the chiller itself, etc. Compact Heat Recovery Sytem by Using a Plate-type Heat Exchanger Hitachi s heat recovery unit consists of a small heat exchanger and is compactly designed. This recovery unit utilizes the energy of making chilled water to supply hot water. Therefore, hot water is supplied for free, and the capacity of the boiler can be reduced. It can supply 60 C hot water (at 00% operation), and its COP is improved. Refrigerant Characteristic Comparison No. Refrigerant (Refrigerant Type) R (HCFC) R4a (HFC) R40A (HFC) ODP (Ozone Depletion Potential) GWP (Global Warming Potential) Cooling Capacity 0.055,700 00% 0,00 6% 0,000 40% Standard Unit Condenser Heat Recovery Unit Condenser Heat Exchanger Hot Water 4 Amount of Refrigerant 00% 6% 7% EXV Comp. EXV Comp. 5 GWP x Amount of Refrigerant,700,09,40 In terms of GWP (Global Warming Potential), R40A is not more environmentally considerate than other refrigerants. However, since the quantity of refrigerant required for equivalent cooling capacity is smaller (see the table), R40A has less impact on the environment than other refrigerants.

Although the operating pressure is larger because the cooling capacity is high, we have succeeded in achieving weight-saving by applying the wealth of technology that we have accumulated through the development of our air conditioners. Moreover, for one-cycle machines, the foundation, transportation, lifting and grounding work required to install the chiller can be reduced because the installation area is greatly decreased. 7 Hitachi Hitachi Water-cooled Chillers Chillers 8
