摘　　要：对铁路冷藏车R134a替代R12进行了相关的试验研究。通过模拟计算、试验数据整理、图形化处理,并对照理论计算的结果。试验表明,采集获得的数据与理论计算有很好的符合。R12多应用于冷冻冷藏设备,用R134a替代后,基本的热力参数都和R12系统接近,但设备的制冷性能会有小幅的下降,制冷量将减少15%左右。对于安全性要求高和易泄露的场合,R134a是R12的最佳替代物。This is a refiigerated rail vehicle R134a replace RI2 tests analyzed. Through simulation, test data collated graphics processing, and control the results of theoretical calculations. That test data and theoretical calculations have a good meet. R12 more in refi＇igerated equipment, R134a replaced, the basic thermodynamic parameters and the system nearly R12, but the refiigeration equipment performance will decline slightly, refrigeration will be reduced by around 15%. Security requirements for high workability leaked occasions, R 134a is the best substitute of R1 2.
