Faculty of Engineering – University of Kerbala has discussed the M.A. thesis which is entitled “air distribution index in Evaluating Air quality Improvement adoption mixing ventilation based on occupant’s density “. It is prepared by Atheer Hamizah Saber.
The study includes an evaluation of indoor air quality and thermal comfort of ventilation system by mixing with the density of the occupants, where different rooms (an isolated room and two non-isolated rooms) are simulated with different shapes of air distributors (a rectangular side distributor and a circular ceiling distributor for the isolated room) and (a linear side distributor and a circular ceiling distributor for the two non-isolated rooms).
The study concludes that the indoor air quality and thermal comfort decrease and concentration of carbon dioxide increases when the density of the occupants increases, with a preference of rectangular side distributor in isolated room. Regarding the two uninsulated rooms, the results confirm the preference of circular ceiling distributor.
