ABSTRACT:
An apparatus is described for applying a fine mist of water to an air conditioner condenser coil for increasing the heat transfer thereof. A water source under normal utility pressure is tapped for flow into a reduced diameter tube supplying the apparatus. Said tube water is filtered and electrolysis protected by a magnesium element affixed to the tube and to the air conditioner structure. A metering valve used exclusively for metering small flows of liquid Freon-type refrigerant, is modified and adapted for exclusive use in metering water to the misters. It is conjoined with a temperature sensor bulb filled with expandable refrigerator coolant as a control initiator and which communicates with said valve via a sealed capillary tube to a chamber and diaphragm means. As the sensor bulb is located at the heat exchanger coil, this expansion valve meters water flow control in accordance with the temperature of the heat exchanger, without the use of electricity or dependence on fan power.
