Abstract

The invention provides a refrigerating machine oil composition, a composition of a refrigerant and refrigerating machine oil and an air conditioning system, the refrigerating machine oil composition comprises base oil and a refrigerating machine oil additive, the refrigerating machine oil additive comprises a compound shown in the following general formula (A), wherein R1, R2, R3 and R4 are not all identical straight-chain, branched-chain or aromatic saturated or unsaturated alkyl groups or alkyl groups with the carbon atom number of 3-18. According to the invention, the problem that the polyol ester refrigerating machine oil is poor in lubricity when an HFC refrigerant is used can be solved, and the problems that the refrigerating machine oil is poor in oxidation stability and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a refrigerating machine oil composition, a composition of refrigerant and refrigerating machine oil, and an air-conditioning system. Background technique [0002] According to the requirements of the Montreal Protocol, and considering the problem of ozone depletion, the use of CFC (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons) as refrigerator refrigerants has been restricted and replaced by HFCs with zero ozone depletion potential. (hydrofluorocarbons). At the same time, the refrigerating machine oil used as the lubricating oil of the refrigeration system has also developed from the widely used mineral oil to various synthetic lubricants currently on the market. Synthetic ester lubricating oils, especially polyol esters, are emerging lubricants because It has the advantages of good thermal oxidation stability, lubricity, viscosity-temperature perfor...
