Document Type and Number:
WIPO Patent Application WO/2022/048175
Kind Code:
A1
Abstract:
A gas supply system of a gas bearing for a compressor, an operation method and a refrigeration system. The gas supply system of a gas bearing for a compressor comprises: a first compressor (1) and a refrigeration cycle path in which the first compressor (1) is located, the gas bearing being provided on the first compressor (1); a gas supply tank (3); a gas intake pipe (4), which communicates the gas supply tank (3) with a first portion of the refrigeration cycle path; a gas outlet pipe (5), which communicates the gas supply tank (3) with the first compressor (1); a return pipe (6), which communicates the gas supply tank (3) with a second portion of the refrigeration cycle path; and a regulating valve (61), which is provided in the return pipe (6), the opening of the regulating valve (61) being adjustable so as to regulate the gas flow within the return pipe (6). In a normally stable operating state of the first compressor (1), the gas pressure at the first portion is greater than the gas pressure at the second portion. The gas pressure within a gas supply tank is regulated by means of a regulating valve on a return pipe so as to provide a stable pressure gaseous refrigerant to a gas bearing, the structure is simple, operation and control are convenient, and reliability is high.
