Air cooling refrigerator and dehumidifying method thereof

Abstract

The invention provides an air cooling refrigerator and a dehumidifying method thereof. The air cooling refrigerator comprises a refrigerator body; a refrigeration chamber which is limited in the refrigerator body; an evaporator which cools flowing air; an air supply flue which is configured to supply the air cooled by the evaporator to the refrigeration chamber; an air return flue which is configured to convey the air from the refrigeration chamber to the evaporator for cooling; and at least one semiconductor refrigeration module which has a first temperature change end and a second temperature change end. The first temperature change end of each semiconductor refrigeration module is arranged in the air return flue; and each semiconductor refrigeration module is configured to allow the first temperature change end and the second temperature change end to serve as a refrigeration end for reducing temperature and a heating end for raising the temperature under control, so that the air entering the air return flue flows through the first temperature change end and the evaporator in sequence, and water therein is condensed at the first temperature change end. Before the air with higher humidity in the refrigeration chamber is returned to the evaporator, the water is condensed and removed at the first temperature change end, so that the frosting quantity of the evaporator is largely reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-cooled refrigerator and a dehumidification method thereof. Background technique [0002] The evaporator of the air-cooled refrigerator is set independently from the storage compartment, and the air cooled by the evaporator is delivered to the storage compartment through the blower fan and the air duct. Since the air temperature is always lower than the compartment temperature, there is no compartment frost problem. However, the humidity of the air returning from the refrigerator to the evaporator is high, and frost will form on the surface of the evaporator. An increase in the amount of frost on the evaporator will seriously affect its heat exchange efficiency, thereby affecting the refrigeration efficiency of the refrigerator and the stability of the room temperature. [0003] At present, the defrosting method commonly used in air-cooled refrigerators is...
