根据《蒙特利尔议定书》规定,发达国家在1996年停用CFC类物质,发展中国家应在2010年停用。目前国际上对CFC类物质禁用的时间有加快的趋势。我国是CFC物质生产和消费的大国,做好电冰箱、电冰柜和空调业的CFC替代工作,不仅对环境保护有着十分重要的意义,也关系到我国在国际社会上的环保形象。因此提早禁止使用CFC物质,用新型制冷剂来替代,我国也正在快速发展。由于生产企业对制冷剂的替代没有采取统一的方案,各个企业使用的新型制冷剂也不相同,从现有的市场上看,用F12的替代物有R—134a和R—600a等几
Under the Montreal Protocol, developed countries banned CFCs in 1996 and developing countries should be discontinued in 2010. At present, the ban on CFCs in the world is accelerating. China is a big country for the production and consumption of CFCs. To do a good job of replacing CFCs in refrigerators, freezers and air-conditioners is not only of great significance for environmental protection but also of our country’s environmental protection in the international community. Therefore, the early ban on the use of CFC substances, with a new type of refrigerant to replace, our country is also rapidly developing. As the manufacturer of alternative refrigerant did not take a unified program, all enterprises use the new refrigerant is not the same, from the existing market point of view, with F12 alternatives R-134a and R-600a, etc.
