ABSTRACT:
A cooling system which utilizes a movable frame positioned within a duct. The moveable frame has an evaporative pad and where a nozzle is positioned to spray water onto the evaporative pad such that the weight of the water causes the frame to move to a lower position, thereby shutting-off the water flowing to the nozzle. As the water in the evaporative pad evaporates, the frame shifts to an upper position where the water is again sent through the nozzle to the evaporative pad, and the cycle repeats itself.
