| Abstract: | 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. |
