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.
The HCFC22 ternary substitutes HFC32 / HFC143a / HFC134a and HFC32 / HFC125 / HFC152a are proposed. The analysis of the theoretical refrigeration cycle performance under standard air conditioning conditions shows that the thermodynamic properties and the cycling performance of the two components are similar to those of HCFC22 under the recommended composition. Has the potential to replace HCFC22 in air conditioning cycle.
