Abstract: A self-contained mobile air-cooling apparatus that can be moved to specific areas for auxiliary or primary cooling as needed. The cooling apparatus has a refrigeration compressor interconnected to an expansion evaporator coil and a condenser coil. A blower draws in ambient air via a return opening and through the evaporator coil giving off cooled air. Refrigerant from the evaporator coil is circulated through a water cooled condenser coil in an enclosure giving up its heat to the water. The water is circulated over the condenser coil in the enclosure and selectively to a storage tank via an outlet control valve.
