Refrigerator and refrigeration method thereof

Abstract

The invention discloses a refrigerator. The refrigerator comprises a refrigerator body, wherein the refrigerator body comprises a plurality of storage chambers; a refrigerating system, wherein the refrigerating system comprises a compressor, a condenser, a freezing evaporator, a liquid storage device, a first one-way valve, a pump and a cold storage evaporator; and a water inlet of the liquid storage device is connected with the freezing evaporator, an air outlet of the liquid storage device is connected with the compressor, a water outlet of the liquid storage device is connected with the first one-way valve, the first one-way valve is connected with the pump, and the pump is connected with the cold storage evaporator. A controller is configured to obtain a freezing evaporator temperature of the freezing evaporator. When the temperature of the freezing evaporator is smaller than a preset evaporator temperature threshold value, the first one-way valve is opened, so that the pump works; and the cold storage temperature of the cold storage chamber is obtained. When the cold storage temperature is smaller than a preset cold storage temperature threshold value, the first one-way valve is closed, so that the pump stops working. The invention further discloses a refrigeration method of the refrigerator. By adopting the refrigerator and the refrigeration method thereof, the normal refrigeration of the refrigerator can be ensured, and meanwhile, the compressor can be prevented from generating liquid impact in the operation process.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator and a refrigeration method thereof. Background technique [0002] At present, the traditional refrigerator refrigeration system is mainly composed of a compressor, a condenser, an evaporator and a capillary tube. The refrigerant is vaporized from liquid to gas in the evaporator to absorb the heat in the refrigerator. The gaseous refrigerant is compressed by the compressor into a high-temperature and high-pressure refrigerant. The gas is then discharged into the condenser, and the condenser condenses the gas into a liquid, then flows through the capillary tube and then flows into the evaporator, where it continues to vaporize and absorb heat to cool down. Such a cycle is repeated continuously to achieve the purpose of refrigeration. However, the existing refrigerators usually only use the compressor refrigeration cycle system, the electric power of the compre...

Problems solved by technology

However, the existing refrigerators usually only use the compressor refrigeration cycle system, the electric power of the compressor is relatively high, and it needs to consume a large amount of energy, and the common compressor refrigeration cycle is used, which may easily cause liquid shock during the operation of the compressor, thereby Affect the service life of the compressor
