Title:
GAS SUPPLY SYSTEM FOR SUSPENSION BEARING, AND REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/035665
Kind Code:
A1
Abstract:
A gas supply system for a suspension bearing, relating to the technical field of refrigeration. The gas supply system comprises: a compressor (100), comprising a suspension bearing; a first circulation assembly, comprising a condenser (120), and an evaporator (110) communicating with the condenser (120), wherein the condenser (120) communicates with an exhaust port of the compressor (100), and the evaporator (110) communicates with a gas suction port of the compressor (100); and a second circulation assembly, comprising a gas supply tank (200) and a gas supply box (210), wherein the gas supply tank (200) communicates with the suspension bearing and is used to supply gas to same, and the gas supply box (210) comprises an outer cavity (212) and an inner cavity (211) arranged in the outer cavity (212), the inner cavity (211) being a deformable cavity; the evaporator (110) communicates with the gas supply tank (200) by means of the inner cavity (211), and the inner cavity (211) obtains a gas-state refrigerant from the evaporator (110); and a liquid is filled between the outer cavity (212) and the inner cavity (211). A pressure difference between the outer cavity (212) and the inner cavity (211) is adjusted by means of the phase change of the liquid so as to force the inner cavity (211) to deform, such that the inner cavity (211) supplies gas to the gas supply tank, thereby improving the stability of the gas supply system. Further disclosed is a refrigeration system.
