Title:
REFRIGERATION CYCLE DEVICE, HEAT EXCHANGER, AND REFRIGERANT DISTRIBUTOR
Document Type and Number:
WIPO Patent Application WO/2024/084543
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device with a suppressed imbalance of a liquid refrigerant. A refrigeration cycle device 1 according to the present disclosure comprises a compressor, a load-side heat exchanger, a decompression device, and a heat source-side heat exchanger. Refrigerant subjected to heat exchange by the heat source-side heat exchanger is compressed by the compressor, and the state of the refrigerant flowing into the heat source-side heat exchanger is a two-phase state of gas and liquid. The heat source-side heat exchanger comprises: a refrigerant flow channel section that forms a flow channel through which flows, in the flow direction with a vector component of the direction perpendicular to the direction of gravity, the refrigerant in the two-phase state of gas and liquid; a refrigerant distributor having a plurality of refrigerant outflow holes provided such that the refrigerant flowing through the refrigerant flow channel section flows outward and is aligned along the flow direction, and a protrusion projecting from an inner wall surface of the flow channel of the refrigerant flow channel section; and a plurality of heat transfer tubes through which flows the refrigerant that has flowed out from the refrigerant outflow holes of the refrigerant distributor.
