Title:
COOLING/HEATING VAPOR INJECTION SYSTEM AND VAPOR INJECTION SYSTEM MODULE USED THEREIN
Document Type and Number:
WIPO Patent Application WO/2023/068645
Kind Code:
A1
Abstract:
The present invention provides a cooling/heating vapor injection system comprising: a compressor that compresses and circulates a refrigerant; a first branch part into which the compressed refrigerant is introduced to be branched; a first refrigerant line which is branched from the first branch part to allow the refrigerant to move therein, and has a condenser and a first expansion valve disposed therein; a second refrigerant line which is branched from the first branch part to allow the refrigerant to move therein, and has an indoor unit and a second expansion valve disposed therein; a gas-liquid separator into which the refrigerant passing through the first refrigerant line or the second refrigerant line flows; and a second branch part into which the refrigerant passing through the gas-liquid separator flows, wherein the gas-liquid separator moves a liquid-phase refrigerant to the second branch part, and moves a gas-phase refrigerant to the compressor.
