Title:
AIR-COOLED REFRIGERATOR AND DEHUMIDIFICATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/006572
Kind Code:
A1
Abstract:
Provided are an air-cooled refrigerator (100) and a dehumidification method thereof. The air-cooled refrigerator (100) comprises a refrigerator body (101) defining a refrigeration compartment (10); an evaporator (40) for cooling air flowing therethrough; an air-blowing channel (11) used to supply the air cooled by the evaporator (40) to the refrigeration compartment (10); an air return channel (12) used to transport the air from the refrigeration compartment (10) to the evaporator (40) for cooling; and one or more semiconductor refrigeration assemblies (50) having respective first temperature-varying ends and respective second temperature-varying ends. The first temperature-varying end of each semiconductor refrigeration assembly (50) is disposed in the air return channel (2). The semiconductor refrigeration assembly (50) is controllable such that the first temperature-varying end and the second temperature-varying end respectively serve as a refrigeration end for lowering a temperature and a heating end for raising the temperature, such that the air entering the air return channel (12) flows through the first temperature-varying end before flowing through the evaporator (40), thereby condensing moisture in the air at the first temperature-varying end. Before the air with a high humidity in the refrigeration compartment (10) returns to the evaporator (40), the moisture contained therein has condensed and removed at the first temperature-varying end, thereby significantly reducing frost build up at the evaporator (40).
