制冷剂R134a与R润滑油互溶特性的探讨

Study on the Intersolubility of Refrigerant R134a and R Lubricating Oil

本文以目前制冷装置中惯例采用的R134a制冷剂与某美国品牌的R润滑油为例,进行了二者的互溶特性研究,从而得到了该品牌润滑油与R134a在不同混合比下的互溶特性、蒸汽压值、温度的变化规律,因此得到了该品牌润滑油在民用建筑空调系统商用压缩机领域的经济适用混合比例。

Taking R134a refrigerant commonly used in refrigeration unit and R lubricant of an American brand as an example,the mutual solubility of refrigerant and lubricant is studied,and the results are obtained.The reciprocal solubility,vapor pressure and temperature of the brand lube oil and R134a at different mixing ratios were studied.Therefore,the economic and applicable mixing ratio of the brand lube oil in the field of commercial compressors of air conditioning systems in civil buildings was obtained.
