IIR documentSummary
Due to Montreal protocol and F-gas regulation, low global warming potential (GWP) refrigerants have been studied for replacement of existing refrigerants, such as R-134a, R-410A, and R-404a. In this study, recent research trends on the heat transfer characteristics of low GWP refrigerants are investigated. Low GWP refrigerants of R-1234yf, R-1234ze, R-1233zd, R-32, and CO2 showed several disadvantages such as reduced heat transfer rate, high pressure drop, and unstability, but still had competitive performance compared to the existing refrigerants. The detailed performance of these low GWP refrigerants was compared to that of the existing refrigerants.
