针对替代工质Ｒ１５２ａ及Ｒ２２／Ｒ１５２ａ与冷冻机润滑油的相溶性问题进行了实验研究；建立了一个油与制冷剂的相溶性实验台，并分别对３种成分的Ｒ２２／Ｒ１５２ａ及纯质Ｒ２２和Ｒ１５２ａ与４种不同类型的润滑油进行了实验测试，测试的温度范围为一３５～８０℃，获得了各制冷剂与各种油的临界溶解温度的图表，并记录了不同温度下的相溶现象，这些结果为进一步开发和选择与Ｒ２２／Ｒ１５２ａ相适应的冷冻润滑油提供了实验依据．
The compatibility of R152a and R22 / R152a with refrigerating machine oil was studied experimentally. A test bench for compatibility between oil and refrigerant was set up. The R22 / R152a and R22 And R152a with four different types of lubricants were tested in the test temperature range of a 35 ~ 80 ℃, obtained the critical temperature of each refrigerant and various oil dissolution diagram, and recorded at different temperatures of the phase These results provide an experimental basis for further development and selection of frozen lubricating oil suitable for R22 / R152a.
