Title:
GAS/LIQUID SEPARATOR AND REFRIGERANT CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/186130
Kind Code:
A1
Abstract:
A gas/liquid separator that comprises: a main body part (140) that is formed from a tubular member that forms a refrigerant passage that has a fixed passage cross-sectional area; and a case part (145) that houses one section of the main body part (140). A lower end part of the main body part (140) is provided with a gas-phase refrigerant outlet (14c), and a spiral part (141) of the main body part (140) is provided with a plurality of through holes (141a). The case part (145) is provided with a liquid storage space (145a) that stores liquid-phase refrigerant that flows out of the through holes (141a) and with a liquid-phase refrigerant outlet (14b) that discharges liquid-phase refrigerant stored in the liquid storage space (145a). The total opening area of the through holes (141a) that are arranged on a refrigerant-flow upstream side is greater than the total opening area of the through holes (141a) that are arranged on a refrigerant-flow downstream side, which suppresses discharge of gas-phase refrigerant and refrigerating machine oil into the liquid storage space (145a).
