摘　　要：对几种常见的制冷剂系统用润滑油与CO_2制冷剂的相溶性进行分析、总结;阐述了制冷剂/润滑油的材料相容性试验方法和装置原理,并基于高压反应釜法,选取两种不同牌号的PAG润滑油,对CO_2/润滑油的材料相容性进行试验测定。This paper analyzed and summarized the miscibility of CO2 refrigerant with several common lubricants used in re- frigerant system. The materials compatibility test methods and devices of the refrigerant/lubricant were described in detail. Based on the autoclave method, two different types of PAG lubricants were selected, and the materials compatibility of CO2/lubricants was identified through test.
