Abstract:

An air and water cooling system includes an evaporator tank partially filled with water with a vacuum pump maintaining a partial vacuum in the tank. A spray of water is directed from a header into the tank, and the partial vacuum effects an evaporation of some of the sprayed water so as to absorb heat from the main pool of water contained within the tank. This cooled water supply may then be pumped through a cooling coil positioned within a heat exchanger, and a flow of air through the heat exchanger will acquire a desired air cooling effect. The water in the cooling coil is then pumped back to the spray header positioned within the evaporator tank to complete the closed cycle. Since the vacuum pump will result in the removal of evaporated water, a float operated water makeup feed is provided to maintain a constant level of water within the evaporator tank.
