【Abstract】 The performances of refrigerator refrigeration cycle with the blend refrigerant HFC152a/HFC125 were theoretically calculated and analyzed in this paper. Experimental study on the main performances of refrigerator refrigeration cycle was conducted using HFC152a/HFC125 substituting for CFC12 and HFC152a/HCFC22 under the condition of different proportion and different charge amount of HFC152a/HFC125. The experimental results indicate that the refrigeration performance of refrigerator can meet the national standard with appropriate proportion of HFC152a/ HFC125 and optimal charge amount. For the environmentally friendly nature and excellent refrigeration performance for refrigerator system, HFC152a/HFC125 can be an appropriate refrigerant for the new generation refrigerator.更多还原
