Summary

The EPA's (Environmental Protection Agency's) NRMRL (National Risk Management Research Laboratory) has evaluated lower global warming alternatives for HFC-134a in motor vehicle air conditioning. Four pure chemicals and one azeotropic mixture were identified and evaluated as alternative refrigerants for conventional systems, but were found to be unsuitable. The four pure chemicals were HFC-227ca, HFC-227ea, HFC-245cb and HFE (hydrofluoroether)-143a. The azeotropic mixture was 51.7 weight percent HFC-134 and 48.3 weight percent HFC-245cb. The evaluation process and results are described in the paper.
