摘要
自从科学家们发现氟氯碳化合物(以下简称CFC)对臭氧层的破坏及其对人类生态环境的危害以来,引起了全世界的关注,并已开展了一系列国际性的行动。本文首先综合介绍了近年来在CFC限用、替代剂研究方面的历史回顾和蒙特利尔协定及其实施动向;其次介绍了CFC替代剂寻找的途径,替代计划及主要替代剂的热物理性质,最后简述了CFC限用对当前制冷空调设备业的影响以及某些国际动向。
In recent years scientists have found that Chlorofluorocarbons (CFC) cause the ozone depletion and bring serious problems to the human environment. The CFC issue has attracted the attention of the whole world and given rise to global actionIn this paper, the historical recall in the CFC phaseout and research development in the CFC alternatives are first introduced. The Montreal Protocol and its current state of implementation are also included. The way for searching CFC alternatives and the project of CFC alternatives as well as the thermophysical properties of main alternativcs are also mentioned. Finally, the international trends and the influence on the refrigeration and air conditioning equipments as a result of CFC phaseout arc doalt with.It is hoped that this paper will promote the research work on the alternative technology of CFC in China.
