Abstract

A method and apparatus for increasing the efficiency of an air conditioning system. Misting the air conditioning system'"'"'s condenser with water cools the condenser and enables the system to more rapidly condense the refrigerant therein. By increasing the rate at which the refrigerant is condensed, energy and wear and tear on the system is reduced. Control of the misting is important, and sensing environmental and other present metrics to assist that control increases the efficiency offered by the present method and apparatus.
