摘要
《蒙特利尔议定书》签订后,随着CFCs的停止生产,其在大气中的含量缓慢降低,但臭氧层的恢复,还需要一段时间。部分可以使用的HCFCs和作为CFCs替代物的HFCs浓度的上升加剧了温室效应。本文介绍了全球变暖潜能(Global Warming Potential,GWP)的计算方法,分子结构和分子寿命是影响工质GWP的2个因素。新合成的制冷剂对地球生态的长期影响难以预料,从对环境的长期安全来看,第四代工质应回归自然工质。
After the sign of the Montreal Protocol,with the discontinued production of CFCs,the content of CFCs in the atmospheric was reduced slowly.But the recovery of the ozone layer will take some time.The increase of the HCFCs and the HFCs exacerbates the greenhouse effect.This article describes the calculation method of GWP(Global Warming Potential).The molecular structure and the molecular life are two factors that affect the GWP.The long-term effects of newly synthesized refrigerants on the earth are difficult to predict.From the long-term safety of the environment,the fourth generation of refrigerant should return to the natural working fluid.
