摘　　要：对氟化醚类工质三氟甲醚(HFE143a)用作冰箱制冷剂进行了全面的理论分析.比较了新制冷剂HFE143a与冰箱制冷剂CFC12、HFC134a、HC600a和HFC152a/HCFC22等的基础热物理性质.对它们的冰箱标准工况制冷循环性能和变工况制冷循环性能进行了详细的理论计算及分析.新制冷剂HFE143a的制冷性能与CFC12和HFC134a的制冷性能基本相似,而耗电指标却优于它们,所以适应更高环境保护的要求,完全适合做新一代的冰箱制冷剂.Fluorinated ether substance F-methyl methyl ether(HFE143a) used as a refrigerant for refrigerator is analyzed in detail. The thermophysical properties of the new refrigerent HFE143a and the original refrigerant CFC12, HFC134a, HC600a and HFC152a/HCFC22 are compared. The performances of refrigerator refrigeration cycle of standard operating condition and that of variable operating condition are calculated and analyzed theoretically. The result indicates that the refrigeration performance of HFE143a is similar to CFC12 and HFC134a, and the former's energy consumption is lower than the latters'. As a new type of refrigerant for refrigerator, HFE143a can meet the highter environment request.
