Refrigerator and refrigerating system thereof

Abstract

The invention provides a refrigerator and a refrigerating system thereof. The refrigerating system comprises a compressor, a condenser, an anti-condensation device, a capillary tube, a frozen evaporator, a refrigeration evaporator and a switching unit, wherein the entrance of the condenser is connected with the exit of the compressor; the entrance of the anti-condensation device is connected withthe exit of the compressor and is in parallel with the condenser; the switching unit is provided with a first entrance and a second entrance as well as a first exit, a second exit and a third exit, the first entrance is connected with the exit of the anti-condensation device, the second entrance is respectively connected with the first exit and the exit of the condenser, and the switching unit isused to switch connection or disconnection between the first entrance and the first exit. According to the embodiment of the invention, the refrigerator refrigerating system can automatically switch on or off the anti-condensation device, therefore, the load of the refrigerator can be reduced, the startup rate of the refrigerator can be reduced, the refrigerating efficiency can be improved and the energy consumption of the refrigerator can be reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a refrigerator and its refrigeration system Background technique [0002] Due to the large temperature difference between the inside and outside of the refrigerator, a "cold bridge" is formed at the junction of the inner and outer shells of the box, and the heat insulation performance of the refrigerator door seal is poor, which reduces the temperature around the refrigerator door. If its temperature drops to the dew point temperature relative to the air humidity, condensation will occur. This not only causes troubles to the user, but also produces corrosion to the casing. [0003] At present, in order to prevent condensation, most traditional refrigerators are equipped with anti-condensation devices at places prone to condensation. However, during use, the anti-condensation devices are always on, which increases the load on the refrigerator and reduces the co...

This not only causes trouble to the user, but also causes corrosion to the cabinet.

[0003] At present, in order to prevent condensation, most traditional refrigerators are equipped with anti-condensation devices at places prone to condensation. However, during use, the anti-condensation devices are always on, which increases the load on the refrigerator and reduces the cooling efficiency of the refrigerator. increased energy consumption
