The objectives of this research were to predict contaminant concentration distribution in occupied zone and contaminant removal efficiency as a function of an occupied zone obstruction level, air distribution method, air change rate, cooling load and contaminant source non-uniformity. The final objective was to develop a concentration variation coefficient to be used for design of air distribution systems. Concludes that the room air distribution method results in contaminant concentration non-uniformity inside the occupied zone.
