Abstract The paper gives results of compressor calorimeter tests with hydrofluorocarbon(HFC)-245ca and HFC-245fa as alternatives for the refrigerant chlorofluorocarbon (CFC)-11. Tests were performed in a semi-hermetic compressor at evaporating temperatures from 1 to 13 C and condensing temperatures from 40 to 60 C. In these ranges, the capacities and efficiencies of HFC-245ca were confirmed to be lower than of CFC-11, while both capacities and efficiencies of HFC-245fa were significantly higher. The higher-than-expected efficiencies and capacities for HFC-245fa were a result of the higher compressor efficiencies.
