This thing is a fan-powered air mixer that fits into a standard round air conditioner outlet.These outlets use an adjustable cone to blow cold air along the ceiling, which provides a even temperature distribution in the room.During winter however, while the aircon operates in reverse cycle for heating, this outlet arrangement only provides a hot ceiling.The obvious solution is to remove the adjustable cone, which allows a column of warm air to exit the outlet, hit the floor and distribute across the floor. Thus achieving yet again an even room temperature.This approach has two drawbacks - one is the noticeable column of air and the other is the somewhat industrial look of the outlet.This fan-thing hooks into the outlet and widens the column of air, making it a lot less noticeable. It also makes the outlet look more interesting. The shown color scheme is for the kid's room. :-)
