Optimization of Air Distribution in A Non-Ducted Concealed Type Fancoil Unit Heat Exchanger

Abstract

In this study, increasing efficiency of a heat exchanger as a sub part of concealed ceiling type fan coil unit is aimed. Accordingly, by determining rotational speed of fans based on actual design; generated air distribution in dry condition on heat exchanger is investigated via computational fluid dynamics software. Significant low air distribution is detected in lower and higher sides of the heat exchanger. In order to create solution to this issue and to increase efficiency, by designed air distributor, homogenized air distribution is targeted. As a conclusion, differentiation of air velocities and air distribution is investigated based on various angles. By means of the distributor with an optimum design angle, air distribution is improved and more homogenous air distribution is achieved.
