摘　　要：本文对氟化醚类工质三氟甲醚(简称HFE143a)用作冰箱制冷剂的性能与现有冰箱制冷剂HC600a进行了对比。首先比较了新制冷剂HFE143a和现有冰箱制冷剂CFC12、HFC134a、HC600a和HFC152a/HCFC22等的基础热力性质。然后对HFE143a、HC600a和CFC12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。分析表明:HFE143a完全适合做新一代冰箱制冷剂。The thermodynamic properties and the refrigeration performances of Fluorinated ether substance F-methyl methyl ether (HFE143a, CH3OCF3) and isobutane (HC600a), both used as a refrigerant for refrigerator were compared in this study. The thermophysical properties of the new refrigerant HFE143a and the original refrigerants CFC12, HFC134a, HC600a and HFC152a/HCFC22 were compared firstly, and the performances of refrigerator refrigeration cycle of standard operating condition and that of variable operating condition for F-methyl methyl ether, isobutane and CFC12 were calculated and analyzed theoretically. The results show that HFE143a is a suitable refrigerant for refrigerator.
