  • Patent number: 12504208
    Abstract: A refrigerator, comprising a cooling loop. The cooling loop has a first flow path in which a compressor, a condenser, a capillary tube, and an evaporator are sequentially connected for circulating a refrigerant. The cooling loop comprises: a hot gas bypass tube, configured to form a second flow path that enables the refrigerant compressed by the compressor to flow from the compressor to the evaporator; a three-way valve, provided in the first flow path between the compressor and the condenser and connected to the hot gas bypass tube; and a two-way valve, provided in the first flow path between the condenser and the capillary tube. The three-way valve can enable the refrigerant discharged from the compressor to flow to the condenser or the hot gas bypass tube, and the two-way valve can be switched off to cut off the flow of the refrigerant discharged from the condenser.
