Abstract

The invention discloses a device for reducing evaporator frosting. The device comprises a compressor, a condenser, a drying filter, a capillary tube and an evaporator; the outlet end of the capillary tube is connected to the outlet end of the evaporator through two branch pipelines in parallel, the two branch pipelines in parallel are the first branch pipeline and the second branch pipeline, a solenoid valve is arranged on the first branch pipeline, and an auxiliary capillary tube and a frosting device are sequentially arranged on the second branch pipeline in the flowing direction of refrigerant. The invention further discloses a method for reducing evaporator frosting. Compared with the prior art, the device has the advantages that the frosting device condenses water vapor in air on the frosting device before the evaporator, frosting quantity on the evaporator is reduced, heat exchange efficiency attenuation of the evaporator is reduced, the defrosting cycle of the evaporator is prolonged, the heat exchange effect of a refrigerator is improved, and the overall power consumption of the refrigerator is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a device and method for reducing frosting of an evaporator. Background technique [0002] With the development of the times, the functions of refrigerators have been gradually improved. The emergence of air-cooled refrigerators has solved the shortcomings of direct-cooled refrigerators that cannot be automatically frosted. Wide attention of refrigerator manufacturers and scholars. The increase of the frost layer will affect the heat transfer efficiency of the evaporator, reduce the heat transfer capacity of the evaporator, and then affect the cooling effect of the entire refrigerator. The existing defrosting methods include contact defrosting heaters and thermal radiation defrosting heaters. The power of defrosting heaters is generally relatively high. Reducing the defrosting interval of the evaporator can improve the heat exchange effect of the evaporator, but at the same...
