Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138059
Kind Code:
A1
Abstract:
An air conditioning device comprises a heat source device, a plurality of indoor units, and a relay device. The heat source device comprises: a heat source-side flow rate regulating valve that is connected to a heat source-side heat exchanger and that regulates the flow rate of refrigerant flowing to the heat source-side heat exchanger; a bypass pipe that is connected in parallel with the heat source-side heat exchanger; a bypass flow rate regulating valve that is provided in the bypass pipe and that regulates the flow rate of refrigerant flowing to the bypass pipe; and a gas-liquid separating unit that is connected to the heat source-side heat exchanger, the bypass pipe, a high-pressure pipe, and a low-pressure pipe, that causes liquid-state refrigerant flowing to the heat source-side heat exchanger and gas-state refrigerant flowing to the bypass pipe to be mixed and discharged to the high-pressure pipe when the refrigerant flows to the high-pressure pipe, and that separates the refrigerant flowing from the low-pressure pipe into liquid-state refrigerant flowing to the heat source-side heat exchanger and gas-state refrigerant flowing to the bypass pipe when the refrigerant flows from the low-pressure pipe.
