Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2024/009395
Kind Code:
A1
Abstract:
This refrigerator comprises a compressor that compresses a refrigerant, a condenser that condenses the refrigerant, a flow path switching device that switches the flow path through which the refrigerant flows, a capillary tube that causes the refrigerant to expand, an evaporator that causes the refrigerant to evaporate, and a suction tube that is provided between the evaporator and the compressor. The capillary tube is provided inside the suction tube and has a first capillary tube that has a spiral shape, and a second capillary tube that is provided so as to abut the outer circumferential surface of the suction tube and has a spiral shape. The Cv value of the first capillary tube is different from the Cv value of the second capillary tube, and the flow path switching device causes the refrigerant that has flowed out of the condenser to flow to at least any one among the first capillary tube and the second capillary tube.
