Airflow in a room with floor-supply displacement ventilation
Traditional side-wall-supply displacement ventilation generates recirculations in the occupied zone, although it provides better indoor air quality than mixing ventilation. The recirculation presents the risk of cross infection. This investigation studies floor-supply displacement ventilation by using perforated floors and floor diffusers. This research aims at high cooling loads without draft risk. This research is being conducted by both experimental measurements and computer simulations.
