Abstract: The apparatus is a heat exchange unit for cooling interior rooms of commercial and/or residential structures. The unit includes a compressor and blower mounted within a base. A lid of the base has an elongated heat exchange tube mounted thereon. The heat exchange tube has an interior liner with a coil structure mounted to the outside surface thereof. An outer liner enclosed the interior liner and associated coil structure. Both the interior and exterior liners are composed of a perforated metallic material. The vertical heat exchange tube is enclosed with a baffle at the top portion thereof. The baffle functions to force air moving upward to travel in an outward and downward direction toward the base and outside of the liners through the perforations. In an alternative embodiment, the vertical heat exchange tube may include a intermediate tube mounted between the interior and exterior tubes. The intermediate tube also has coils wrapped about the perimeters.

Abstract: An environmentally adaptable exterior heat exchange unit with a pot like base and a vertical component extending from the base. An artificial plant is incorporated into the structure to blend the unit with its environmental surroundings. The unit could resemble a fir tree, a shrub, a bush, a tree or the like. A compressor and condensing coil are located within the base which will reduce noise levels and increase efficiency of heat exchange. A set of vertically extending heat exchange coils circulate a second coolant and extend upward from the base and can be moved relative to the base without disturbing coolant flow or the components housed within the base. The unit can be operated with the lid off and mainatin refrigerant and coolant circulation. The refrigerant coil is run within the coolant coil in a tube-in-tube arrangement within the base to enhance heat exchange. The coolant tubes then carry the heat outside the base.
