汽车空调制冷剂R134a代替R12的研究

通过对R134a与R12两种制冷剂性质的对比,分析了R134a代替R12后对空调系统产生的影响以及系统作出的相应改变,指出R134a具有作为汽车空调制冷剂应具备的各种热工性能、安全性和环境性能等条件,总结出R134a代替R12的可行性与必要性。

Study on the substitution of the R12 with R134a on automobile air-conditioning refrigerant

Through the contrast of the nature of the R12 and R134a,analyzes the corresponding changes as well as the impact of the air-conditioning system after the refrigerant having been substituted,points out that R134a have the performances,safety and environment the conditions that the car airconditioning refrigeranting medium should have,summarizes the feasibility and the necessity of R134a replace to R12.
