Abstract: The air duct system of refrigerator is one of the core components of refrigerator products, and its flow field distribution characteristics directly affect the refrigeration efficiency of refrigerator. Taking a two door air-cooled refrigerator as an example, the initial air duct structure is simulated, optimized and tested. The results show that the new air duct structure increases the total air output by about 17.44%, and improves the air distribution ratio of the refrigeration room, so that the refrigerated compartment has better temperature uniformity, and reduces the risk of condensation in the refrigerator compartment.
