The paper discusses the ethane-based hydrofluoroether, HFE-125, as a replacement for R-502 in low-temperature refrigeration. Modeling indicates that its performance can be nearly equal to that of R-502. The paper describes testing of HFE-125 and several industry refrigerant blends proposed as R-502 alternatives in a compressor calorimeter under supermarket operating conditions.
