Abstract
Provided in the present application are an air duct system and a refrigeration appliance provided having the same. The air duct system comprises a drying system and a cooling system arranged in cooperation with each other, the cooling system has an evaporator and an air return port and an air supply port arranged on the two sides of the evaporator, and the drying system is disposed between the air return port and the evaporator, and comprises an air compressor and an air storage tank connected to each other; the air discharged by the air return port passes in sequence through the air compressor and the air storage tank and then flows to the evaporator, so that the air passing through the evaporator is dried, avoiding the problems of frosting and low efficiency.
