Alternatives to high GWP HFC refrigerants: chiller applications.

Résumé

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 R134a, R410A, and R22. An alternative for R123 also has been proposed. Test results for some of the refrigerants are presented. There are no “ideal” refrigerants in the list of alternatives to R134a, R410A, and R22 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.
