Abstract: A refrigerator includes a compressor. The refrigerator further includes a condenser. The refrigerator further includes a refrigerating chamber evaporator. The refrigerator further includes a freezing chamber evaporator. The refrigerator further includes a first capillary that is configured to reduce refrigerant pressure. The refrigerator further includes a second capillary that is configured to reduce refrigerant pressure. The refrigerator further includes a third capillary that is configured to reduce refrigerant pressure. The refrigerator further includes a 4-way valve that includes an inlet that is connected to the condenser, a first outlet that is connected to the first capillary, a second outlet that is connected to the second capillary, and a third outlet that is connected to the third capillary, and that is configured to selectively distribute refrigerant to at least one of the first capillary, the second capillary, or the third capillary.
