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