Title:
GAS BEARING AIR SUPPLY SYSTEM AND CONTROL METHOD AND CONTROL APPARATUS THEREFOR, AND REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/042238
Kind Code:
A1
Abstract:
The present application relates to the technical field of refrigeration, and discloses a gas bearing air supply system for use in an air suspension compressor, comprising: a plurality of electric heating units, each electric heating unit comprising an air outlet, a liquid inlet, and a communication port; the air outlet of each electric heating unit is in communication with an air supply port of the air suspension compressor by means of an air supply path; the liquid inlet of each electric heating unit is in communication with a condenser in the refrigeration system in which the air suspension compressor is located by means of a liquid intake path; and the communication port of each electric heating unit is in communication with an evaporator in the refrigeration system in which the air suspension compressor is located by means of a communication path. After the liquid intake path and the communication path of the electric heating unit are connected, a partial loop is formed, and pressure difference is used to implement automatic liquid supplementation of the electric heating unit. The refrigerant pump on the liquid intake path in the prior art can be omitted, increasing reliability. Also disclosed in the present application are a control method and a control apparatus for use in the gas bearing air supply system and a refrigeration system.
