Low GWP refrigerant for heat pump.

Number: No 198

Author(s) : KIM S., ABBAS L., ZHANG L., TURNER D.

Summary

Climate change concerns have driven the development of lower Global Warming Potential (GWP) fluorocarbon refrigerants and transition away from incumbent HFC refrigerants is already in progress in multiple applications. In this paper, R-516A, a ternary azeotropic refrigerant with GWP of 131 (AR5) and essentially a near drop-in of R-134a, is evaluated as a refrigerant for air-to-water chiller and heat pump applications. Performance and application map of R-516A are compared to the R-134a baseline as well as other HFO solutions.
