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.
