Abstract
Abstract Apparatus for attachment to an air conditioner condenser for applying a mist of water or other liquid to the coils and fins of the condenser to improve the heat transfer capability of the condenser. The apparatus includes a spray nozzle, support structure for the spray nozzle, fluid conductors, a fluid valve member, a temperature sensing member, and a valve control member. The temperature sensing member, through the valve control member, causes the spray to operate only when certain predetermined temperature conditions exist. The temperature sensing member is positioned so that it, as well as the coils and fins of the condenser, receives water sprayed as a mist by the spray nozzle. Thus, the temperature conditions which exist in the coils and fins also exists in the temperature sensing member.
