Document Type and Number:
WIPO Patent Application WO/2022/224390
Kind Code:
A1
Abstract:
A refrigeration cycle device according to the present invention is provided with a heat source side unit, a relay unit, and a plurality of load side units. The heat source-side unit and relay unit are connected by a low-pressure pipe and a high-pressure pipe, and the relay unit and each of the plurality of load side units are connected by a liquid branch pipe and a gas branch pipe. The heat source side unit is provided with a compressor that compresses refrigerant, a path switching valve that switches the path of the refrigerant according to the mode of operation, and a heat source side heat exchanger. The relay unit is provided with one six-way valve or two four-way valves connected to each of the plurality of load-side units, and a gas-liquid separator in which an inlet thereof is connected to the high-pressure pipe. The one six-way valve or two four-way valves are connected to a gas outlet of the gas-liquid separator, a liquid outlet of the gas-liquid separator, the gas branch pipe, the liquid branch pipe, and the low-pressure pipe.
