所有汽车空调制冷系统都会通过密封件和软管上的微孔泄漏一些制冷剂。现在的汽车采用新型R-134a制冷剂,这种制冷剂泄漏性更强,并且制冷剂的逐渐泄漏对新型空调系统的制冷性能影响很大。
All automotive air conditioning and refrigeration systems leak some refrigerant through the tiny holes in seals and hoses. New cars now use the new R-134a refrigerant, which is more leak-free and has a significant effect on the refrigeration performance of new air-conditioning systems due to the gradual leakage of refrigerant.
