摘　　要：根据有关制冷剂替代的新的国际会议精神,通过热泵标准工况下的理论制冷制热循环特性的计算分析,认为摩尔成分为0.55/0.45的非共沸混合工质HFC32/HFC152a是HCFC22很有希望的一种替代工质。而且从温室效应、可燃性等方面的应用特性进行了研究分析。In this paper, according to new international congress of refrigeration, cycling performances of thetheoretical refrigeration and heating were calculated under the standard working condition of heat pump. The resultsshow that a non-azeotropic mixture HFC32/HFC152a whose molefraction is 0.55/0.45 is a promising alternative toHCFC22. And researches on practical properties of HFC32/HFC152a which was exploited as alternative refrigerant inheat pump are carried out mainly from greenhouse warming, flammability and toxicity.
