Evaporative Cooling System

Abstract

An improved evaporative cooling system with an enclosed insulated chamber having an inlet, an outlet and a blower in the system located downstream of the outlet to draw air to be cooled through the chamber. A foraminous filter extends across the inlet to clean the incoming air of large solid particles. An electric motor is mounted partially across the inlet opening, having a rotating shaft and supporting a disc for rotation on the shaft. A reservoir of water chilled to between about 55 and 40 degrees Fahrenheit is supported within the bottom of the chamber and positioned for engagement by the disc during rotation, which upon rotation flings chilled water adhered droplets upwardly away from the reservoir in a fan-shaped pattern to further clean, cool and humidify the air which passes through a fog-like curtain formed by the chilled water droplets moving within the chamber, prior to exiting the chamber.

1 . An improved evaporative cooling system comprising,
 an enclosed insulated chamber having an inlet, an outlet and a blower in the system located downstream of the outlet to draw gas through the chamber;   a foraminous filter extends across the inlet to clean the incoming gas of large solid particles;   an electric motor mounted partially across the inlet opening, having a rotating shaft and supporting a disc for rotation on the shaft;   a reservoir of chilled water supported within the bottom of the chamber, positioned for engagement by the disc during rotation, which upon rotation flings chilled water adhered droplets upwardly away from the reservoir in a fan-shaped pattern to further clean, cool and humidify the gas which passes through a fog-like curtain formed by the chilled water droplets moving within the chamber, prior to exiting the chamber.   
   
   
       2 . The system of  claim 1 , wherein the temperature of air exiting the chamber is between 5-7 degrees Fahrenheit below wet bulb temperature. 
   
   
       3 . The system of  claim 1 , wherein the water within the reservoir is chilled to between 55 and 40 degrees Fahrenheit. 
   
   
       4 . The system of  claim 1 , wherein the temperature of air exiting the chamber is as great as 7 degrees Fahrenheit below wet bulb temperature 
   
   
       5 . The system of  claim 1 , wherein the gas cooled within the system is room or outside air. 
   
   
       6 . The system of  claim 1 , wherein the foraminous filter is a polymer material. 
   
   
       7 . The system of  claim 1 , wherein the enclosed insulated chamber includes a refrigeration assembly, a heat exchange unit and a pump for supplying water from and to the reservoir to the heat exchange unit, having coolant material which is cooled by the refrigeration assembly. 
   
   
       8 . The system of  claim 1 , wherein the pump is positioned on the bottom of the reservoir submersed within water. 
   
   
       9 . An improved evaporative cooling system comprising,
 an enclosed insulated chamber having an inlet, an outlet and a blower in the system located downstream of the outlet to draw air to be cooled through the chamber;   a foraminous filter extends across the inlet to clean the incoming air of large solid particles;   an electric motor mounted partially across the inlet opening, having a rotating shaft and supporting a disc for rotation on the shaft;   a reservoir of water chilled to between 55 and 40 degrees Fahrenheit is supported within the bottom of the chamber, positioned for engagement by the disc during rotation, which upon rotation flings chilled water adhered droplets upwardly away from the reservoir in a fan-shaped pattern to further clean, cool and humidify the air which passes through a fog-like curtain formed by the chilled water droplets moving within the chamber, prior to exiting the chamber.   
   
   
       10 . The system of  claim 9 , wherein the enclosed insulated chamber includes a refrigeration assembly and a heat exchange unit for chilling the water within the reservoir. 
   
   
       11 . The system of  claim 10 , wherein the enclosed insulted chamber further includes a pump for supplying water between the reservoir and the heat exchange unit. 
   
   
       12 . The system of  claim 11 , wherein the pump is positioned on the bottom of the reservoir submersed in water.
