Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/139702
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises: a heat source side unit having a compressor and a heat source side heat exchanger; a plurality of load-side units each having a throttle device and a load-side heat exchanger; and a relay unit connected between the heat source side unit and the load-side units and having a plurality of three-way valves that are provided corresponding to the load-side units so as to switch the flow of refrigerant, the relay unit distributing low-temperature refrigerant to a load-side unit that performs cooling operation and high-temperature refrigerant to a load-side unit that performs heating operation. The three-way valves switch the flow of refrigerant so that the refrigerant flowing out of the heat source side unit flows into the load-side unit, or the refrigerant flowing out of the load-side unit flows into the heat source side unit, depending on the operating conditions.
