Defrosting system and method for freezer

Abstract

A defrosting system includes a freezer body and a dehumidification device with a desiccant rotor. The desiccant rotor includes a treatment region and a regeneration region. The dehumidification device is configured to reduce moisture in the freezer body and removes frost in the freezer body by means of the desiccant rotor. The dehumidification device includes a treatment air inlet and a treatment air outlet. The treatment air inlet is configured to draw to-be-treated air out of the freezer body. The treatment air outlet is configured to transport dry air, dehumidified by adsorption of the desiccant rotor, back into the freezer body. By adopting the defrosting system for a freezer, no condensate water is produced in the whole dehumidification process of the freezer, and no water needs to be drained out of the freezer.
