SharePerformance testing of R502 replacements based on R32-R125-R134a.
Author(s) : HAINES G. H., DEKLEVA T. W., LOW R. E.
Summary
With the impending phase-outs of CFCs and HCFCs, there has been considerable industry activity in trying to find alternatives. The paper describes the work in designing alternatives to R502 based on ternary blends of R32-R125-R134a. With a backdrop of the environmental considerations, it includes results of trials in which R502 has been replaced in systems with R32-R125-R134a blends in supermarket applications; in these instances, the performances with the retrofit refrigerants have been comparable with, or sightly better than the original R502 performance.
