Abstract
The invention discloses an environment friendly energy-efficient refrigerant oil composition. The invention is characterized in that: the composition has the following components by mass percentage: 95-98% of composite base oil, 0.5-2% of composite anti-oxidant, 1-3% of composite extreme pressure anti-grinding agent and 0.002-0.005% of composite anti-foaming agent; each performance index of the refrigerant oil of the present invention reaches the usage requirement, and has the advantages of good low viscosity, low condensation point, high viscosity index, viscosity temperature performance, low temperature performance, low volatility, low temperature fluidity, chemical stability, thermooxidizing stability, anti-corrosive property, lubricity, oil gas separating property, refrigerant compatibility, material adaptability, high biodegradability, etc., and is suitable for a enclosed refrigeration compressor using CO2, HCS, CFCS, HCFCS, HFCS as refrigerants. The invention can be blended for producing a product which satisfied the performance requirements of refrigerant oil L-DRB / B with viscosity grades N15, N22, N32, N45 and N68.
Description
technical field [0001] The invention relates to an environment-friendly and energy-saving refrigerating machine oil. Background technique [0002] The freezer is one of the most important components in compression refrigeration equipment. The compression refrigeration system is composed of four major components: compressor, condenser, expansion valve and evaporator. Its main working principle is to use refrigerant gasification to absorb the surrounding heat, lower the temperature and then cool down; The condenser turns the high-pressure gaseous refrigerant into a liquid again, and then vaporizes, so that the cycle works continuously. This kind of refrigeration system is widely used in various fields such as our industrial equipment and living equipment. However, the normal operation of the refrigeration system is inseparable from the lubrication, sealing, heat dissipation and anti-corrosion functions of the refrigeration oil. The quality and performance of the refrigeratio...
