Number: 0266

Author(s) : RYDKIN I., NAKAUE T., LEON A.

Summary

The introduction of novel Hydrofluorooelefin (HFO) component R-1132E allows for significant improvements in Global Warming Potential (GWP) and thermophysical performance of ultralow GWP refrigerant blends. This paper will provide laboratory test results with R-474A, a binary blend of R-1132E, R-1234yf and provide an comparison and LCCP. It was found that R-474A as a drop-in replacement demonstrated up to a 50% heating and cooling capacity increase compared to R-1234yf and a up to a 30% Coefficient of Performance (COP) increase over R-744 (CO2)
