Summary

Global warming has become a common problem facing human society, in order to alleviate the greenhouse effect, the search for lowcarbon environmental-friendly protection of the refrigerants has become a hot spot in high temperature heat pump (HTHP) technology. This paper assesses the feasibility of HFO1336mzz(Z)andHFO1233zd(E) with low global warming potential(GWP) value, as alternatives in HTHP systems. The basic properties and cycle performance are calculated and analyzed.The results show that HFO1233zd(E) has a larger specific volumetric heat capacity than HFO1336mzz(Z), however the pressure ratio of HFO1336mzz(Z) is better than HFO1233zd(E). In addition, the coefficient of performance of thebinary mixture consisted by the two refrigerants with different mass fraction is calculated, and the optimal ratio of the binary mixture was suggested by theoretical calculation. The theoretical calculation provides reference for the research and application of the two types of refrigerants in the HTHP system in the future.
