Summary

CFC-11 was the main chemical used in low-pressure chillers. The phase-out of CFC-11 has led to the use of HCFC-123 as the refrigerant of choice in new low-pressure chillers. However, HCFC-123 will eventually be phased-out, too. Therefore there is a need to identify non-chlorine-containing alternatives for use in low-pressure chillers. Investigations showed that HFC-245ca had lower volumetric capacity and cycle efficiency than CFC-11, while HFC-245fa had significantly higher volumetric capacity but slightly lower cycle efficiency. The present work presents the results of compressor calorimeter tests with HFC-245ca and HFC-245fa as CFC-11 alternatives. Tests were performed in a semi-hermetic compressor at evaporating temperatures from 1 to 13 deg C and condensing temperatures from 40 to 60 deg C.
