Numerical Analysis of Air Flow Field in Air-cooled Refrigerator with Large Capacity and its Design Improvement
摘要
Abstract
The quality of food reservation in refrigerator directly relies on the flow field distribution and the temperature distribu -tion.And the flow field distribution and the temperature distribution are determined by the fan system ,air inlet/outlet position and internal structure of a refrigerator ,which is a big difficulty in the design of air-cooled refrigerator with large capacity .In this pa-per,CFD simulation technology is introduced to the design of air-cooled refrigerator with large capacity .Firstly,3D simulation model of an air-cooled refrigerator with large capacity is set up and the simulation of internal flow field is performed .Then,accord-ing to the simulation results,some big design improvements have been made ,such as,centrifugal fan replacing axial fan and modi-fication of air duct system .By doing this , the air circulation has been increased and the noise of the refrigerator has been de-creased effectively due to the improved flow field distribution .The feasibility and correctness of this paper has been verified by ex-perimental test .关键词
