Abstract
The air conditioning applications in mosques are considered as one of the important HVAC applications, which prayers comfort depend on the behavior of the airflow, the distributions of temperatures and relative humidity and concentration of carbon dioxide due to high occupancy load of prayers. So, the present thesis is devoted to numerically investigate the influence of location and number of persons on airflow properties in mosque. The work focuses on airflow patterns, thermal behaviour and carbon dioxide dispersion in mosque where large number of prayers standing. The effectiveness of an airflow system is commonly assessed by the successful removal of sensible and latent loads from occupants with additional of attaining air pollutant at a prescribed level to attain the human thermal comfort conditions and to improve the indoor air quality. Commercially packaged floor mounted air conditioning unit is a typical unit for such applications, due to the advantages it possesses over other types of HVAC systems and units
