Abstract:
1. An apparatus for minimizing the cost of operation of an air conditioner by applying a controlled minimum volume of fine water mist onto a heat exchange condenser with refrigerant-containing coils which is a part of the air conditioner, the condenser including spaced water conduits affixed thereupon, said apparatus comprising a plurality of spaced water mister nozzles for spraying a fine mist upon said coils and the moving air flow surrounding them, a water supply line connected to said water conduits and said misters, a sacrificial anode containing magnesium strip or bar connected to the water source and to structures exposed to Galvanic electrolysis when wetted, a particulate filter between the water supply and the expansion valve unit, a non-electrical, metering expansion valve dedicated for use with water, a temperature sensor bulb, intimately associated with said valve as a fused structure, operating against a moveable metal diaphragm therein, said temperature sensing portion positioned so as to sense the temperature conditions of said condenser coils and transmitting control by vapor pressure means to said diaphragm in said valve through capillary tube means.
