| 摘要: |
| 低GWP值制冷剂R1234ze(E)（trans-1, 3, 3, 3-tetrafluoropropene）作为R134a较为理想的替代品而被关注，但其单一成分的热力学性能和传输特性并不理想，在R1234ze(E)中混入R32成分可以有效改善其热力学性能。本文概述了低GWP值工质R1234ze(E)及其与R32混合物的热物性特征、传输特性及系统运行性能方面的研究现状，并与目前常用的制冷工质进行比较分析，指出R1234ze(E)与R32混合工质有望成为新型低GWP值替代工质。 |

| Abstract: |
| Over the past few years, more attention have been paid to the new low GWP refrigerant R1234ze(E), as a kind of ideal alternative of R134a. But, thermodynamic property and transfer characteristic are not good enough. To achieve better thermodynamic performance, mixtures of R1234ze(E)/R32 was carried out. The recent development on thermodynamic, transfer characteristic and drop-in experiments of R1234ze(E) and R1234ze(E)/R32 mixtures are introduced and compared with some common used refrigerants in the present paper. It is shown that R1234ze(E) and R32 mixtures is expected to be the new low GWP value refrigerants in the future. |
