REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2022/143413
Kind Code:
A1
Abstract:
A refrigerator comprises a cooling circuit. The cooling circuit has a first flow path in which a compressor, a condenser, a capillary tube, and an evaporator are connected, and a refrigerant is circulated. The cooling circuit further comprises: a hot gas bypass pipe configured to form a second flow path that allows the refrigerant compressed by the compressor to flow from the downstream portion of the compressor to the upstream portion of the evaporator; and an opening/closing unit for opening or closing the hot gas bypass pipe. The opening/closing unit enables the refrigerant discharged from the compressor to flow into the first flow path or the second flow path. An end portion of the downstream side of the hot gas bypass pipe is configured to be connected with respect to the upper side of a first pipeline in a vertical direction, and the first pipeline is connected to the downstream capillary tube and the upstream evaporator.
