在世界各国的制冷期刊中,就目前工程中所用的大多数氟利昂对地球外臭氧层的有害作用发表了许多不同资料。臭氧层有保护地球免受太阳辐射的有杀伤能力的紫外线的作用。在20年代出现了无毒性、不燃、不易爆、无味的合成制冷剂和化合物(被命名为氟利昂的氯氟烃),长期被认为是无害的。这些制冷剂在工业企业制冷装置和空调系统等方面得到了 In the refrigeration journals in various countries of the world, many different sources have been published on the detrimental effects of most of the freons used in the current project on the extraterrestrial ozone layer. The ozone layer has the damaging effects of UV rays that protect the Earth from the sun’s rays. The non-toxic, non-flammable, non-explosive, odorless synthetic refrigerants and compounds (chlorofluorocarbons designated Freon) have been found to have long been considered harmless in the 1920s. These refrigerants have been obtained in industrial enterprises such as refrigeration equipment and air-conditioning systems
