摘　　要：利用Peng-Robinson(PR)状态方程,对钢厂行车空调器替代工质的热物性建立相应的参数关系方程式,并对这几种替代工质的热力循环进行了性能模拟分析和试验验证,为行车空调器工质的选定进行了有益的探索。By using the state equation Peng-Robinson （PR）, a relative formula of parameters has been set for the thermal physical performance of substituted refrigerant in the air conditioner for travelling crane in steel plant, as well as a simulated analysis and testing comparison of thermal recycle performance have been carried out with several kinds of substituted refrigerant, that is a useful exploration on the selection of refrigerant in air conditioner for travelling crane.
