Description

This report presents the characteristics of lower-GWP chiller refrigerant alternatives offered by refrigerant manufacturers for consideration and testing in the “Low-GWP Alternative Refrigerants Evaluation Program” administered by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). Alternatives have been identified for the chiller refrigerants R-134a, R-410A, and R-22. An alternative for R-123 also has been proposed. Test results for some of the refrigerants are presented. There are no “ideal” refrigerants in the list of alternatives to R-134a, R-410A, and R-22 if “ideal” is defined as having a GWP of 150 or less, an A1 ASHRAE safety rating, and near-zero temperature glide. Refrigerants with GWPs of 700 or more, an A2L safety rating, and – in some cases an appreciable temperature glide – need to be considered for the future.
