Abstract

The invention relates to a refrigerating machine oil composition, comprising polyol ester, semi-hindered phenol type antioxidant, antiwear agent, metal deactivator and acid catcher; wherein the polyol ester is ester product of reaction of pentaerythritol with mixture of isononanoic acid and diethyl hexanoic acid. The refrigerating machine oil composition provided by the invention has good oxidation stability, and oxidation induction period thereof is obviously prolonged compared with the refrigerating machine oil utilizing conventional antioxidant.

Description

technical field [0001] The present invention relates to a refrigerating machine oil composition. Background technique [0002] The widely used chlorofluorocarbons and hydrochlorofluorocarbons in the past have good chemical stability, and they are not easy to decompose in the troposphere when they leak into the air. Chlorine radicals, which are involved in the depletion of ozone and cause damage to the ozone layer in the atmosphere, are currently being replaced by chlorine-free hydrofluorocarbons (HFCs) refrigerants. [0003] Synthetic ester (POE) has good mutual solubility, stability and material compatibility, reliable lubricating performance, safety and environmental protection, and has become the preferred lubricating oil for hydrofluorocarbons (HFCs). [0004] Different from general lubricating oil, refrigeration oil and refrigerant continuously circulate between the outlet of the compressor in the high-temperature area and the evaporator in the low-temperature area. It...
