Defrosting method of series-parallel connection dual-system air-cooled refrigerator

Abstract

The invention discloses a defrosting method of a series-parallel connection dual-system air-cooled refrigerator. The defrosting method comprises a freezing chamber defrosting method and a refrigerating chamber defrosting method, the conditions of the freezing chamber defrosting method and the refrigerating chamber defrosting method are set, a freezing fan motor is controlled to work for P minutes before freezing chamber defrosting electric heating equipment works, after the freezing chamber defrosting electric heating equipment stops working, an electric control device controls a compressor to continue to stop for N minutes and then starts the compressor, and normal refrigeration work is carried out; and a refrigerating chamber is defrosted according to the conditions, and the energy-saving defrosting method is provided. According to the defrosting method, the defrosting process is finely adjusted, the defrosting energy consumption is further reduced, the defrosting interval can be prolonged, and efficient defrosting control is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a defrosting method for a series-parallel dual-system air-cooled refrigerator. Background technique [0002] The defrosting technology inside the air-cooled refrigerator box is to use the fan and air duct system inside the air-cooled refrigerator to blow cold air from the air outlet to the inside of the box to freeze and refrigerate food; with the air circulation, hot air and water vapor are sucked into the return air In the air duct, when passing through the evaporator, it freezes on the surface of the evaporator to form a frost layer, so that the frost inside the box can be removed. [0003] However, the frost layer condensed on the evaporator will affect the refrigeration performance of the air-cooled refrigerator, and even block the circulation of the air, which will cause the temperature of the box to rise, affect the cooling effect, and increase energy consumption.

In addition, the current electric heating equipment uses electric heating tubes, generally with a power of 100W-280W. Since the frequency and time of defrosting are factors that affect the energy consumption of air-cooled refrigerators, the existing air-cooled refrigerators have a low energy consumption during defrosting. high energy consumption
