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, a refrigerated air system with a water-cooled condenser, a swimming pool pump, and a swimming pool or other bulk water storage container. A pump or series of pumps are used to supply water to the evaporative cooler and to the water-cooled condenser from the swimming pool. After the swimming pool water has been supplied to the other components in the system, it is returned to the swimming pool. 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 swimming pool to condense the refrigerant vapors will enable the system to achieve even greater efficiency and will provide an added benefit of lowering the temperature of the water stored in the swimming pool.
