Problems solved by technology

Among them, the price of synthetic oils such as polyether and ester oils is high; paraffin-based mineral oils have poor low-temperature fluidity, high wax content, and are easy to block capillaries and other parts, resulting in no cooling of the system; although naphthenic oils have excellent low-temperature performance and Good solubility in isobutane and propane, but low viscosity index and flash point, poor lubricity, and environmental issues

Abstract

The invention discloses refrigerator oil, a refrigeration compressor and a refrigeration compressor system. Refrigerants adopted by the refrigeration compressor are selected from components of the HCs group. The refrigerator oil comprises alkyl benzene, wherein the distillation range of the alkyl benzene comprises an initial distillation point ranging from 250 DEG C to 310 DEG C and a final distillation point ranging from 470 DEG C to 540 DEG C. The refrigerator oil has the good advantages that the viscosity is low, the flash point is high, the intersolubility with the refrigerants is good, the acid value is low, and the chroma is excellent, so that when the refrigerator oil is used for the refrigeration compressor and the system thereof, good heat stability and chemical stability are achieved, and the energy consumption is low.

Description

technical field [0001] The invention relates to a refrigerating machine oil for a refrigerating compressor, wherein the refrigerating compressor adopts HCs hydrocarbon refrigerant. The present invention also relates to a refrigeration compressor and a refrigeration compressor system containing the refrigeration oil. Background technique [0002] Refrigeration oil plays the role of lubrication, heat dissipation, sealing and noise reduction in the refrigeration compressor, which has an important impact on the performance and life of the compressor and refrigeration system, especially the reliability of the compressor and refrigeration system and the energy efficiency of the refrigeration system close relationship. Considering that most of the equipment currently using hydrocarbon refrigerants is closed refrigeration, the working time of the refrigeration oil is often synchronized with the life of the compressor, which is as long as 10-15 years. Therefore, it is very importan...
