Abstract

A base oil for a refrigeration oil composition and refrigeration oil composition. The base oil comprises an alkylbenzene oil and an ester oil. The ratio of the 120˚C kinetic viscosity of the base oil to the 40˚C kinetic viscosity thereof is 0.23-0.30. A base oil having a viscosity overly decreasing with the increase of the temperature is formed by combining an alkylbenzene oil and an ester oil having a low viscosity and high viscosity index for use and adjusting the ratio of the 120˚C kinetic viscosity of the base oil to the 40˚C kinetic viscosity thereof.

Description

technical field [0001] The invention relates to the field of refrigerating machine oil, in particular to a base oil for a refrigerating machine oil composition, a refrigerating machine oil composition and a composition for refrigerating. Background technique [0002] The compression refrigeration system is composed of a refrigeration compressor, a condenser, an expansion valve, an evaporator, etc. The working principle is to use the refrigerant to vaporize and volatilize, absorb the heat of the surrounding medium, reduce the temperature for cooling, and then pass the refrigerant to the air through the compressor. It returns to liquid, then gasifies again, and the cycle repeats. This kind of refrigeration system is widely used in household appliances such as refrigerators and air conditioners, industrial equipment such as cold stores and cold rooms, and commercial equipment such as showcases, beverage and ice cream machines. The compressor is the heart of the above-mentioned...
