| 摘 要： | 新型制冷剂R1234ze(E)因较低的GWP备受制冷行业关注,其与R32的混合工质作为热泵系统制冷剂的研究也在逐步展开,本文以R1234ze(E)/R32(质量配比:27%/73%,命名为L-41b,GWP=493)混合工质为研究对象,在人工环境室中设计并搭建了空气源热泵测试系统,对比研究了L-41b与R410A在热泵系统中的性能系数COP、压缩机功耗、制热量、排气温度和循环压比。结果表明:当恒定冷凝温度,蒸发温度从5℃增加到13℃时,R410A和L-41b的COP偏差从8.6%缩小到2.8%。当恒定蒸发温度,冷凝温度从30℃提高到42℃时,L-41b的运行性能系数COP的降幅小于R410A,变工况实验表明在相对高温区L-41b替代R410A具有较好的替代性能。
