Abstract

The invention relates to the technical field of refrigeration working media, in particular to refrigerator oil, a working fluid composition containing the refrigerator oil and a compressor using the working fluid composition. The refrigerator oil comprises base oil, an additive and a compound A shown as a formula I. In the formula I, R1 is -H, methyl or ethyl; and R2 is an alkane group of C1-C8. The working fluid composition includes the refrigerator oil and a refrigerant. A working medium used by the compressor is the working fluid composition provided by the second aspect of the invention. The refrigerator oil provided by the invention has good hydrolysis resistance, and is suitable for a refrigeration compressor of a hydrofluorocarbon refrigerant. The adopted compound A can neutralize acidic substances in the refrigerator oil, reduce the acid hydrolysis effect of synthetic ester and improve the hydrolysis stability of the refrigerator oil so as to ensure efficient and long-term operation of the compressor.

Description

technical field [0001] The present application relates to the technical field of refrigerating working media, and in particular, relates to a refrigerating machine oil, a working fluid composition containing the refrigerating machine oil, and a compressor using the working fluid composition. Background technique [0002] In view of the thinning of the ozone layer on the earth's surface during the use of Freon, the refrigeration system is gradually using refrigerants with high environmental protection characteristics to replace traditional refrigerants. Among all kinds of refrigerants at this stage, hydrofluorocarbon refrigerants have the advantages of high efficiency, stability, and low cost, and are currently one of the ideal transitional refrigerants. [0003] Refrigerator oil, which is closely related to the development of refrigerants, has also developed from mineral oil to today's synthetic oil. Synthetic esters are often used as base oils for lubricating oils in refri...
