摘要
提供了在冰箱上应用新型共沸混合工质ＨＦＣ１３４ａ／ＨＦＣ１５２ａ的热力学分析和实验研究。相平衡计算表明，新制冷剂是一种共沸混合物，热力学分析和实验研究表明，新型共沸混合工质ＨＦＣ１３４ａ／ＨＦＣ１５２ａ与原制冷剂ＣＦＣ１２相比有着相似的热工性能，在合适的成分下，有一定的节能效果。文中还对新型共沸混合工质ＨＦＣ１３４ａ／ＨＦＣ１５２ａ应用于冰箱时可能存在的可燃性和充灌问题进行了讨论。
Thermodynamic analysis and experimental study of refrigerant mixture HFC134a/HFC152a which exhibits azeotropic behavior from phase equilibrium calculation were con-ducted. It is found that the new azeotropic mixture has the similiar thermodynamic propertieswith CFC12,and under some suitable composition,the energy saving effect may be achieved. The discussion on the flammability and recharge problem which may exist in refrigerator ap-plication of HFC134a/HFC152a mixture was also presented.
