摘要
探讨了在CRH2型动车组空调制冷系统中使用制冷剂R407C替代R22的可行性,介绍了设计改进方案和改进实施、试验情况,为新一代动车组空调使用环保制冷剂提供了依据。
The feasibility to apply the refrigerant R407C instead of R22 in air-conditioner sets on CRH2 multiple units is discussed.The design improvement scheme and carrying out of the improvement as well as the testing are described,so as to provide basis for applying environment protection refrigerant in air-conditioning for the new generation of multiple units.
