摘要:: 为替代热泵热水器中的R134a工质，选择MIX01（m(R1234ze(E))∶m(R290)=40∶60）、 MIX02（m(R1234ze(E))∶m(R600)=85∶15）和MIX03（m(R1234ze(E))∶m(R600a)=75∶25）进行研究。建立热泵系统热力学模型，利用Matlab软件、调用Refprop物性参数、参照国家标准对3种混合工质进行变工况计算，并与已有的工质R134a进行对比分析。结果显示：3种R1234ze(E)/HCs工质的臭氧损耗潜值（ozone depression potential，ODP）为0，全球变暖潜值（global warming potential，GWP）都小于20，这3种工质均为近共沸工质。其中，MIX01在排气温度、压缩比及单位容积制热量上都优于R134a。

Abstract:: In order to replace the R134a used on the heat pump water heater,〖BF〗MIX01(m(R1234ze(E))∶m(R290)= 40∶60),MIX02 (m(R1234ze(E))∶m(R600)=85∶15),MIX03 (m(R1234ze(E))∶m(R600a)=75∶25) were studied in this paper. The thermodynamic model of the heat pump system was established. Matlab was used for theoretical circular calculation of the mixtures by employing property parameters from Refprop developed by NIST. According to the national standard, the three mixed working fluids were calculated under variable working conditions, and compared with the working fluid R134a. The results showed that the ozone depression potential(ODP) of the three R1234ze(E)/HCs working fluids was 0,and the global warming potential(GWP) was less than 20. All of them belong to nearazeotropic working fluids. Among them,MIX01 was superior to R134a in terms of exhaust temperature, compression ratio and volumetric heating capacity.
