摘要
为了防止臭氧层被破坏和气候变暖,氟氯烃(CFCs)和氢氟氯烃(HCFCs)制冷剂的使用受到严格限制,逐渐被氢氟烃(HFCs),烃,二氧化碳和氨制冷剂所取代。随着制冷剂的变化,概要介绍了多元醇酯,聚烷撑二醇和聚乙烯醚冷冻机油的发展动向。
In order to prevent ozone from destroying and climate chlorofluorocarbons and hydrochlorofluorocarbons were restricted and they were warming, the use of gradually replaced by hydrofluorocarbons, hydrocarbons, carbon dioxide and ammonia. With the change of refrigerant, the developing tendency of polyol esters refrigeration lubricants, polyalkylene glycols refrigeration lubricants, polyethylene ether refrigeration lubricants was introduced briefly.
