Title:
AIR-CONDITIONING SYSTEM WITH MIXED WORKING FLUID
Document Type and Number:
WIPO Patent Application WO/2020/108012
Kind Code:
A1
Abstract:
The present application provides an air-conditioning system with mixed working fluid, comprising: a compressor; a first heat exchanger, and the first heat exchanger communicates with an air exhaust port of the compressor, the first heat exchanger is provided with a first flow channel communicating with a first inlet end and a second flow channel communicating with a first outlet end, and a first gas-liquid separator is further connected between the first flow channel and the second flow channel; the first gas-liquid separator comprises a first inlet, a first liquid outlet and a first gas outlet, the first inlet communicates with the first flow channel, the first gas outlet communicates with the second flow channel, and liquid flowing out of the first liquid outlet can be throttled and heated and then connected to a gas supply port of the compressor for gas supplement. The present application enables more high-boiling point refrigerant working fluid entering the first heat exchanger to improve condensation performance, and further increases the amount of low-boiling point refrigerant working fluid entering the second heat exchanger to improve evaporation performance, thereby solving the problem of poor gas supplement effect of a mixed working fluid gas supplement system, and improving the performance of the air-conditioning system.
