摘　　要：通过对环保工质三氟碘甲烷 (CF3I)的饱和蒸汽压曲线、冰箱名义工况和变工况下循环性能等三方面的理论分析 ,发现CF3I和CF3I的摩尔组成在 5 0 % - 6 5 %范围的CF3I/HC2 90混合工质 ,理论循环性能与CFC12接近 ,具有作为冰箱中CFC12灌注式替代物的潜力。Comparative assessment on the cycle performances of trifluoroiodomethane(CF 3I), CFC12, HFC134a, HC600, HC290, HFC152a/HCFC22, and CF 3I/HC290 was carried out theoretically under standard and various refrigerator working conditions. The results show that CF 3I and CF 3I/HC290 with CF 3I's mole fraction in range of 0.5-65 are potential substitutes to CFC12 for refrigerator applications.
