摘　　要：在制冷、热泵系统中广泛使用的循环工质R2 2由于具有较大的GWP值和ODP值 ,终将被淘汰 .针对工质R2 2的替代研究 ,提出了一种非共沸混合工质R2 90 /R6 0 0a/R12 3(5 0 % / 10 % / 4 0 % ,质量 ) ,并在热泵实验台上做了不同冷凝器或蒸发器进口水温和流量的多种工况实验及分析 .通过将该工质在各工况下的实验结论与相应工况下R2 2的实验结论进行对比分析后 ,发现该物质是替代R2The working fluid R22 is often used in refrigeration and heat pump systems, but it will be replaced in the next several years because its ozone-depletion potential (ODP) and global-warming potential (GWP) are very high. In order to seek some novel working fluids to replace the R22, some experiments on a small refrigeration and heat pump system were performed, and the working conditions were decided at different water temperatures and flow rates in condenser or evaporator, which were compared with those experimental data of R22 in the same working conditions. The non-azeotropic mixtures working fluid R290/R600a/R123 (50%/10%/40%, mass) may become an alternative of R22 for heat pump application.
