Patent ID: 7401472

Claim:
In combination: a first refrigeration system module for heating or cooling an object, said first module comprising: an enclosure having a refrigeration system disposed therein, said refrigeration system including a vapor compression circuit for circulating a refrigerant and having a compressor, a first heat exchanger, an expansion device and a second heat exchanger operably disposed therein in serial order; said first heat exchanger defining a first outward facing surface of said enclosure, said first surface being a thermal exchange surface wherein said first heat exchanger provides thermal communication between said first surface and refrigerant flowing within said first heat exchanger; said second heat exchanger defining a second outward facing surface of said enclosure; said second surface being a thermal exchange surface wherein said second heat exchanger provides thermal communication between said second surface and refrigerant flowing within said second heat exchanger, said first and second surfaces being disposed on opposite sides of said enclosure and having substantially similar surface areas; at least one attachment feature disposed on said module wherein said at least one attachment feature is attached to the object to thereby secure the object in thermal communication with at least one of said first and second surfaces; and a second module wherein said at least one attachment features of said first and second modules are secured together and said first surface of one of said first and second modules is in thermal communication with said second surface of the other of said first and second modules.
