摘　　要：对列车空调用空气制冷机进行了研究,分析了制冷机的压比选择、调节方式和温室效应。结果表明:列车空调用空气制冷机压比应在2—2.5范围内,应采用变压比的调节方式,性能系数在1—1.3范围内,TEWI值小于现用蒸气压缩式系统。The air cycle refrigerator used in train＇s air conditioning system was investigated. The analysis of the pressure ratio, the regulating mode and the the greenhouse effect of the cycle is performed. The results show that, the pressure ratio should be in the range of 2--2.5, the variable pressure ratio should be used in the regulating mode, the coefficient of performance will be in the range of 1-1.3, the value of TEWI of the refrigerator is smaller than that of traditional refrigerator.

关 键 词：列车空调 空气制冷机 压比 TEWI
