Environmentally Adaptive Vac Exterior Heat Exchange Unit
Environmentally Adaptive Vac Exterior Heat Exchange Unit
US Patent:
6085536, Jul 11, 2000
Filed:
Aug 12, 1999
Appl. No.:
9/372830
Inventors:
Fred Evans - Rockville MD
International Classification:
F25D 2312
US Classification:
622591
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.
