Evaporative Pre-cooler Residential Air Conditioning Condenser Coil

摘要

An evaporative pre-cooling system for increasing the efficiency of a residential air conditioner condensing unit utilizing a wet medium in contact with low velocity moving air allowing evaporation to occur across the wet medium thereby reducing the associated dry bulb air temperature of the air moving across the wet pad as the air absorbs moisture. In the present invention, the embodiment of the pre-cooling apparatus encapsulates the condensing unit with a wet cellulose media, water not absorbed during the evaporation cycle is recycled, and water generated by the evaporator coil is discharged into the sump to further reduce tap water consumption. In the embodiment of the present invention, the wet pre-cool mode is thermostatically in parallel with the electrical circuit energizing the pre-cooler system in tandem with the air conditioning compressor motor. The embodiment of the pre-cooling apparatus is constructed of cellulose evaporative pads, plastic top, plastic upper distribution channels, plastic lower water recovery channels, polyvinyl chloride (PVC) piping and fittings for water distribution, plastic frame, PVC for water drains, plastic sump reservoir, and plastic close-off panels providing total recyclability of the embodiment of the complete evaporative pre-cooler enclosure apparatus.
