| 摘 要： | 广泛用于家用电冰箱的制冷剂R12对臭氧层具有严重的损耗作用,为了保护大气环境,R12的替代研究迫在眉捷。文章认为R134a是替代R12的首选。R134a不含氯原子,对大气臭氧层不起破坏作用;具有良好的安全性能(不易燃、不爆炸、无毒、无剌激性无腐性);R134a的传热性能比R12好,制冷系统的改型比较容易,因此,制冷剂的用量可大大减少。

| Abstract: | The refrigerant R12 widely used in home refrigerators has a serious impact for depleting of the ozone layer,in order to protect atmospheric environment the study of alternative for R12 is imminent.This article concludes that R134a is a preferred alternative for R12.R134a does not contain chlorine atoms,there-fore,it can not destroy the ozone layer in the atmosphere.R134a has safe properties(non-flammable,non-explosive,non-toxic,no-erosive);and it has better heating transfer performance than R12.For this rea... |
