REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2023/284589
Kind Code:
A1
Abstract:
A refrigerator, comprising: a refrigeration compartment; a cooling loop, in which a cooling cycle is implemented, wherein, during the cooling cycle, a refrigerant successively flows through a compressor, a condenser, and an evaporator and again returns to the compressor; a hot gas bypass pipe, which is directly connected to a discharge side of the compressor and an intake side of the evaporator; and a fan, which is used for enabling a gas in the refrigerator to flow. The gas is circulated by the fan as follows: gas that passes through the evaporator from bottom to top flows into the refrigeration compartment, and the gas flowing in the refrigeration compartment again returns to a lower side of the evaporator; an inlet and an outlet of a heat exchange pipeline of the evaporator through which the refrigerant flows are matchingly disposed on an upper side of the evaporator; a first defrosting procedure is implemented, wherein hot gas defrosting treatment is performed, in which a refrigerant discharged from the compressor is supplied, by means of the hot gas bypass pipe, to the inlet of the heat exchange pipeline, and, at the same time, gas defrosting treatment is performed, in which gas flowing in the refrigeration compartment 7 is supplied to the lower side of the evaporator.
