In rooms ventilated by mixing ventilation, in order to remove contaminants from the occupied zone, the goal of the air distribution system is to achieve a low and even concentration distribution in the room.
The experiments showed that the contaminant distribution in a room always will depend on the location of the contamination source and in practice also on the supplied air flow rate and the contaminant density.
The results showed that it is important for the removal of contaminants in a room that the ventilation system is working in the same direction as the existing buoyancy forces.
