传统的汽车空调制冷装置是用氟里昂R_(12)为工质,但R_(12)会使大气臭氧层产生“空洞”而加剧温室效应,造成紫外线直接辐射到地球表面从而破坏生态环境,这引起了社会愈来愈广泛的重视,为此1992年联合国在哥本哈根召开的保护臭氧层第四次协议会上郑重宣布将1987年《蒙特利尔协议书》中停止使用氟里昂的日期提前,发达国家提前到1996年,发展中国家提前到2000年。我国已在1991
The traditional automobile air conditioning and refrigeration device uses Freon R_ (12) as working fluid, but R_ (12) will cause “ozone depletion” in the atmospheric ozone layer and exacerbate the greenhouse effect, causing ultraviolet radiation to directly irradiate the Earth’s surface and thus destroy the ecological environment, which causes As a result, the United Nations solemnly announced at the 4th UN Agreement for the Protection of the Ozone Layer in Copenhagen in 1992 that the date of the withdrawal of Freon in the 1987 Montreal Protocol should be advanced ahead of the developed countries to 1996 Year, the developing countries advance to 2000. My country was in 1991
