A study on ventilation system using a two dimensional turbulence k-ε model with the assumption that the fluid is incompressible and non-isothermal is presented. The purpose of this study is to predict the distribution of air velocity and temperature in main hall Masjid Sultan Salahuddin Abdul Aziz Shah in Shah Alam. When the airflow and temperature distribution have been predicted by the computer software FLUENT, the comfort level can easily be determined. Nine cases have been conducted to examine the effects of input air velocity, air velocity from the fan heli and fan air flow direction to the percentage of consumer dissatisfaction. Mixing characteristics of comfort have been analyzed under different air supply velocities, temperatures and fan velocities. The fan velocity directions involved two conditions which are the upwards and downwards directions. The results from the research in the form of air velocity and temperature distributions are important in determining the comfort level which is unsuitable for the user. It was found that cases of 3,4, 5, 6 and 7 show the effect of a very good comfort with the percentage of PPD between 10% to 20%. The location of heli fans also affects the impression of comfort in the main hall. The comfort level of this area can be improved by modifying the position and increasing the number of fans in the hall
