摘　　要：低全球变暖潜能值(Global Warming Potential,GWP)制冷剂R1234ze(E)作为R410A较为理想的替代品而被关注。但是纯R1234ze(E)的热力学性能和传输特性并不出色。近期研究表明R1234ze(E)中混入R32成分可以有效提高其热力学性能。本文在空气源热泵测试实验系统中以R1234ze(E)/R32(质量配比为27%/73%,命名为L-41b,GWP为493)混合工质为研究对象,考察了R1234ze(E)和混合工质L-41b在实际热泵系统中的运行性能。与常规制冷工质R410A的运行性能在相同工况下进行了对比,在相对高温区中L-41b对R410A具有良好的替代性能。研究结果为R1234ze(E)及其与R32混合工质的产品设计开发提供了参考数据。Refrigerant R1234ze(E)with low GWP(Global Warming Potential)has gotten much attention as an ideal substitute for R410A.However,the thermodynamic property and transfer characteristic of pure R1234ze(E)are not outstanding.Recent study shows that the mixture of R1234ze(E)/R32could achieve better thermodynamic performance.In this paper,the mixed refrigerant of R1234ze(E)/R32(mass ratio is27%/73%,named as L-41b,GWP is493)was chosen as the research object for the experimental system,and the performance of R1234ze(E)and mixed refrigerant L-41b in the air source heat pump system was analyzed.Comparing with the operation performance of refrigerant R410A under the same working condition,L-41b shows good performance as alternative of R410in the relatively high temperature zone.The research results provide reference for design and development of product with new refrigerant R1234ze(E)and the mixed refrigerant of R1234ze(E)/R32.
