摘要
介绍了适用于不破坏大气臭氧层制冷剂ＨＦＣ１３４Ａ（１，１，１，２－四氟乙烷）的ＲＩＰＰＲＥＦＯＬＳＬ制冷压缩机油的各种理化性能。以多元醇酯为基础油并加有多种添加剂所组成的ＳＬ制冷压缩机油具有较好的与ＨＦＣ１３４Ａ的互溶性和热化学安定性，良好的润滑性、抗水解性和低温性能，适用于不同类型、不同要求的以ＨＦＣ１３４Ａ作制冷剂的制冷压缩机中。还评述了ＨＦＣ１３４Ａ和氟里昂ＣＦＣ１２制冷剂对制冷压缩机油性能要求上的异同以及酯类油和烃类冷冻机油在性能方面的差异。
The performance of RIPP REFOL SL refrigerator oil used with the non-ozone-depleting refrigerant HFC 134A is described. The SL refrigerator oil, made of polyol ester type base fluid withvariety of additives, possesses good performance such as miscibility with HFC 134A refrigerant, thermaland chemical stability, lubricity, hydrolytic stability and low-temperature properties. This oil is suitablefor use in different types and for different requirements of refrigerators with HFC 134A refrigerant. Thedifferences between the performance requirements for the refrigerator oil used with HFC 134A and thatused with CFC 12 are described. The performance of the polyol ester type base fluid as a refrigerator oil,compared with that of naphthenic oil are also describecl.
