NUMERICAL STUDY OF HEAT TRANSFER PERFORMANCE ON THE AIR SIDE OF EVAPORATOR FOR A DOMESTIC REFRIGERATOR

Abstract The Computational Fluid Dynamics (CFD) method has been applied to predict the heat transfer performance of evaporator on the air side for a domestic refrigerator in this article. From the numerical results, it can be shown that nonuniformities exist on the distributions of air velocity, air temperature, and local heat transfer rate. The flow maldistributions are mainly caused by the ill-designed supplier of frozen storage room. They could deteriorate the overall heat transfer performance of evaporator and may result in the refrigerant degradation on the refrigerant side.
