Title:
GAS SUPPLY SYSTEM OF GAS BEARING FOR COMPRESSOR, OPERATION METHOD AND REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/077788
Kind Code:
A1
Abstract:
A gas supply system of a gas bearing (11) for a compressor, an operation method and a refrigeration system. The gas supply system of the gas bearing (11) for a compressor comprises: a refrigeration cycle pipeline, comprising a first compressor (1), the gas bearing (11) being provided in the first compressor (1); and a second compressor (41), used for pressurizing part of gaseous refrigerants in the refrigeration cycle pipeline to provide same to the gas bearing (11). In a case where the gas pressure in the refrigeration cycle pipeline does not reach the gas pressure required by the gas bearing (11), a part of the gaseous refrigerants in the refrigeration cycle pipeline are pressurized by means of the second compressor (41) so as to achieve the gas pressure required by the gas bearing (11) to work, thus being able to provide continuous and pressure-stable gas for the gas bearing (11), which helps to ensure the continuous and stable operation of the gas bearing (11).
