Abstract

Abstract: The air volume uniformity and temperature uniformity are key factors which affect the energy efficiency. To analysis the top-mounted force-aired refrigerator with centrifugal fan, numerical simulation and experimental vertification are used and an optimal design of air volume uniformity has been worked out. Firstly, a guide structure should be added near the outlet of the fan to change the direction of air-out. Secondly, the area of air outlet should be modified to enhance the air uniformity. Finally, the experimental verification shows that the temperature difference between left and right part of freezer can be reduced from 3℃ to 0.1℃ with the optimal design.

Key words: Refrigerator, Centrifugal fan, Air volume uniformity, Numerical simulation, Experimental verification
