| 摘 要： | 由于氟利昂类冷媒(CFCs)对臭氧层具有破坏作用,而氢氟烃类冷媒(HFCs)冷媒具有较高的全球变暖潜势(Global Warming Potential,GWP),目前不少国家已研讨在家用空调中使用低GWP的冷媒替代方案,其中一种方案就是以R290替代R22。使用R290作为制冷剂在开发过程中需要解决的一个最重要问题就是冷冻机油的选择和设计。文章通过对家用空调用旋转式压缩机内部润滑状态进行分析,并对不同冷冻机油在R290冷媒下的特性进行研究,提出了R290冷媒下油品设计方法。

| Abstract: | Because CFCs deplete the ozone layer and HFCs have high global warming potentials, many countries have
been reinvestigating low GWP refrigerants as alternatives in household air conditioners, one of which is R290 as the
alternative for R22. But the most important problem is how to choose the suitable lubricant for refrigerant R290. In this
paper, the design method of lubricant was proposed through analyzing the lubrication in rotate compressor of household air
conditioners and studying on properties of several oils in R290 refrigerant. |
