摘　　要：提出了HCFC22的三元替代物HFC32／HFC143a／HFC134a和HFC32／HFC125／HFC152a，标准空调工况下的理论制冷循环性能分析表明两物系在推荐组成下均与HCFC22相近的热力学性质和循环性能，具有在空调循环中替代HCFC22的潜力.Ternary mixtures HFC32/HFC143a/HCF134a and HFC32/HFC125/HCF152a are proposed and discussed as substitutes for HCFC22 in the air-conditioning system. It has been found that both the blends with the recommended compositions have thermodynamic properties and theoretical refrigeration cycle performances close to HCFC22, while HFC32/HFC143a/HCF134a seems more promising with slightly higher COP, specific volumetric refrigerating capacity and lower discharge temperature than HCFC22.
