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.
