Problems solved by technology

[0004] However, due to the inconsistent chemical polarity of HFC refrigerants and HFO refrigerants, currently existing mineral oils, alkylbenzenes, synthetic POE oils, PVE oils, etc. cannot take care of both types of refrigerants at the same time
For compressor products with different refrigerants, different refrigerating machine oils need to be used together, which brings inconvenience to compressor manufacturers and high cost

Abstract

The invention provides a compressor and a refrigerating device. The compressor comprises a shell, a motor and a compression structure, wherein the motor is arranged in the shell; the compression structure is located in the shell and is connected to the motor; the compression structure is internally provided with a refrigerant which comprises a hydrofluoroolefin refrigerant and / or a hydrofluorocarbon refrigerant; engine oil is contained in the shell, the compression structure is partially immersed in the engine oil, and the engine oil comprises base oil and polyalcohol ester, and the polyalcohol ester is formed by compounding polyalcohol and at least one organic acid, the carbon number of which is smaller than or equal to 10. According to the compressor, the refrigerant comprises the hydrofluoroolefin refrigerant and / or the hydrofluorocarbon refrigerant. The engine oil comprises the base oil and the polyalcohol ester, and the polyalcohol ester is formed by compounding polyalcohol and atleast one organic acid, the carbon number of which is smaller than or equal to 10. The engine oil is compatible with the hydrofluoroolefin refrigerant and the hydrofluorocarbon refrigerant simultaneously, so that the universality of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a compressor and a refrigeration device. Background technique [0002] At present, due to the destructive effect of the traditional freon R22 refrigerant on the ozone layer, the use of R22 refrigerant is limited by the Montreal International Treaty and will be discontinued in the future. In addition, as the global temperature warms, considering the global warming factor (GWP), high-GWP refrigerants will eventually be replaced by low-GWP refrigerants. Among them, hydrofluorocarbon refrigerant (HFC) R32, as a chlorine-free refrigerant and one of the candidate refrigerants with a low global warming coefficient GWP, has attracted the attention of the industry due to its environmental protection, high energy efficiency and low cost. , and synthetic refrigerants with R32 as the main body are all concerned by the industry. [0003] In addition, the industry is looking fo...
