For more effective ventilation from the room floor, where polluted air and dust arise, a new ventilation system located on the ceiling has been developed by using fresh intake air and generating a tornadolike vortex to ventilate the air near the floor both locally and directly. In a water tank, which simulated a room space, the same tornadolike vortices were visualized using ink diffused from the base, and the ventilation efficiency was measured. In order to apply this new ventilation system to local cooling, the heat transfer performance at the floor was also investigated.
