NUMERICAL AND EXPERIMENTAL INVESTIGATION OF AIR PERMEABILITY OF AN EVAPORATOR

Abstract

In this study, the air distribution in the evaporator of an industrial type monoblock refrigerator is investigated numerically and experimentally. Using the ANSYS program, 12 different points on the evaporator were determined and the velocity of these points were numerically determined, and the evaporator was divided into 5 different regions and the air flow rate change in these regions was examined. The simulated parts were also measured experimentally in a monoblock refrigerator. As a result, it is observed that there is an unbalanced air distribution on the evaporator, which has a negative effect on cooling performance and energy consumption. Thanks to the fins used to distribute the air flow more evenly, the difference in distribution between the left and right zones of the evaporator is reduced by 10.8 m3/h. As a result, a more balanced flow distribution was achieved with an improvement of approximately 10%.
