Summary

HFE143m is a novel environment friendly refrigerant, but domestic research on is it is very limited. Thermophysical properties correlations of HFE143m and comparison of cycle performance between HFC134a and HFE143m are given in this paper. The results show that the operating pressure of HFE143m is lower than that of HFC134a. The per unit mass cooling capacity and the COP are improved 2.9% and 3.6%, respectively, under the isentropic compression condition. The per unit mass cooling capacity and the COP are improved 2.9% and 16.6%, respectively, when the compressor outlet superheat is 25°C. This novel refrigerant has the potential to replace HFC134a.
