70cSt(40 o C) 이하의 점도를 갖는 PAG를 0.1중량% 이상 20중량% 이하(바람직하게는, 2중량% 이상 10중량% 이하)의 양으로 폴리비닐 에테르 및 에스테르 오일과 같은 합성 윤활유에서 부가함으로써 HFC 냉매 및 불순물과 용해성이 우수한 윤활유를 수득할 수 있다. 따라서 작동유체로서 HFC 냉매와 함께 본 발명의 윤활유를 사용하는 압축기가 장착된 냉동/공조장치에서는 냉동기안 혼합물의 비율편차가 발생하지 않으며 그 결과, 모세관 세척 효율이 감소되지 않는다. 이 경우, 냉동/공조장치에 아무런 변화없이 저비용으로 높은 신뢰성을 갖는 장치를 얻을 수 있다. Addition of PAG having a viscosity of 70 cSt (40 o C) or less in synthetic lubricating oils such as polyvinyl ether and ester oil in an amount of at least 0.1% and at most 20% by weight (preferably between 2% and 10% by weight). As a result, an HFC refrigerant and a lubricant having excellent solubility with impurities can be obtained. Therefore, in the refrigerating / air conditioning apparatus equipped with the compressor using the lubricating oil of the present invention together with the HFC refrigerant as the working fluid, the ratio deviation of the mixture in the freezer does not occur, and as a result, the capillary washing efficiency is not reduced. In this case, it is possible to obtain a device having high reliability at low cost without any change in the refrigeration / air conditioning apparatus.
