Abstract

The invention discloses a module for defrosting in advance, a control method thereof, and refrigeration equipment. The module for defrosting in advance includes: a cooling device, which is arranged in the refrigerated return air duct between the air return port of the refrigerating compartment and the evaporator of the freezing compartment, and is used for condensing the moisture into the evaporator before reaching the evaporator of the freezing compartment. Frost; a defrosting device for defrosting the cooling device when the cooling device is frosted. The invention makes the moist air frost in advance before reaching the evaporator of the freezing chamber, which can prolong the defrosting time interval of the evaporator in the freezing chamber, reduce the air humidity in the refrigeration equipment, and make the frost layer of the evaporator in the freezing chamber thinner. The defrosting time varies, and the temperature fluctuation of the freezer compartment is small.

Description

technical field [0001] The invention relates to the technical field of defrosting, in particular to a module for defrosting in advance and a control method thereof, so as to ensure that the temperature in the freezing chamber is relatively stable. Background technique [0002] At present, the evaporator in the freezer compartment of mainstream air-cooled refrigerators will affect the cooling effect after frosting. If the temperature exceeds 10°C, the refrigeration temperature of the refrigerator fluctuates greatly, which affects the storage of ingredients. [0003] Usually, the air from the air inlet of the refrigerating room passes through the refrigerated return air outlet and the return air passage, and then reaches the evaporator in the freezing room to cool down, and then sends it to the refrigerating room through the air inlet of the refrigerating room. Due to the placement of fruits and vegetables in the refrigerator, and the frequent opening and closing of doors, it ...
