Chilled Evaporative Cooler

Abstract

The present invention comprises a water chilled evaporative cooler that involves chilling water before it flows over evaporative cooler pads. This is an improvement over other methods, because it absorbs additional heat from the air due to the sensible heat that is absorbed when the water is heated from a chilled state to atmospheric temperature before it evaporates. The present invention provides an evaporative cooler which has a means to chill the temperature of the water being supplied to the evaporative cooler pads.

What is claimed is: 
     
         1 . An evaporative cooling system, comprising:
 an air circulation system, comprising:
 at least one air vent; 
 at least one evaporative cooler pad; 
 a fan for drawing air through the at least one air vent and at least one evaporative cooler pad; and 
 a fan motor for powering the fan; 
   a reservoir system for containing water, comprising:
 a basin; 
 a float; and 
 a valve connecting the basin to a water supply; 
   a chilled water system for lowering the temperature of water, comprising;
 a water chiller; 
 a chiller water pump for pumping water from the basin to the water chiller; 
 a chilled water supply pipe for supplying water to the water chiller from the chiller water pump; and 
 a chilled water return pipe for returning water from the water chiller to the basin; 
   a pad water system for saturating the evaporative cooler pads, comprising:
 a pad water pump for pumping water from the basin to the evaporative cooler pads; 
 a pad water supply pipe for supplying water to the evaporative cooler pads from the pad water pump; and 
 means for returning unevaporated water from the evaporative cooler pad to the basin.
