摘　　要：蒙特利尔议定书《修正案》规定ＨＣＦＣ类化学品从２００４年起分阶段削减产量，联合国气候变化框架公约《京都协议》要求限期削减温室气体排放总量，以此为背景探讨了替代冷媒对全球环境问题的影响机理；在比较了两个国际环境协定的管制方法和前提的基础上，分析了ＨＣＦＣ－１２３的环境影响，提出了对ＨＦＣ－１３４ａ优势的三点反思；对两者的使用前景发表了四点看法。Discusses the impact of alternative refrigerants upon the global environment, in the circumstances of HCFCs phasingout from the year 2004 and greenhouse gases reducing in total discharge, according to the amendment to the Montreal Protocol and Kyoto Protocol respectively, and based on a comparison of the control strategies of the two intergovernmental agreements, analyses the environmental consequences of HCFC-123, presents three rethinks of HFC-134a, and predicts the prospects of the two refrigerants.
