ABSTRACT:
The present invention provides a method and apparatus for efficiently using various components as a system for cooling air. The apparatus uses the combination of an evaporative cooler with a water reservoir and a refrigerated air system with a water-cooled condenser. A pump or series of pumps are used to supply water to the evaporative cooler and to the water-cooled condenser from the water reservoir. A mechanism for controlling the hardness of supplied water may also be included. After the reservoir water has been supplied to the other components in the system, it is returned to the water reservoir. During cooler weather, the output air from the evaporative cooler is supplied to a series of ducts and is used to cool the interior of a structure such as a home. When the outside ambient temperature and/or humidity levels exceeds the capabilities of the evaporative cooler for cooling the interior of the structure to the desired temperature, the output air from the evaporative cooler is re-directed to the attic space of the structure and the refrigerated air from the refrigerated air system is used to cool the interior of the structure. By using the output air from the evaporative cooler to cool the attic space, the overall cooling load on the refrigerated air system is reduced. In addition, the use of the water from the reservoir to condense the refrigerant vapors will enable the system to achieve even greater efficiency.
