摘　　要：提出探讨了一种有希望替代 ＨＣＦＣ２２的三元混合工质─ＨＦＣ３２／ＨＦＣ１４３ａ／ＨＦＣ１３４ａ。 理论制冷循环和水合性能分析表明：在推荐组成下该物系的热力学性质与ＨＣＦＣ２２基本相当，理 论制冷循环ＣＯＰ和容积制冷量均略优于ＨＣＦＣ２２，在空调循环蒸发工况下能够形成气体水合物。Ternary mixture HFC32/HFC143a/HFC134a was proposed and discussed as a substitute for HCFC22 in air-conditioning and cool storage air-conditioning system. It was shown that the blend around the composition of 0.2/0.3/0.5 mol would provide almost the same thermodynamic properties as HCFC22, slightly higher COP and volumetric refrigerating capacity than HCFC22, and promising hydrate-forming parameters.
