Abstract:

A vending machine includes a product compartment, a duct opening into the product compartment, and a self-contained refrigeration system. The refrigeration system includes a housing having a first chamber and a second chamber. The first chamber includes first and second openings. The second chamber includes third and fourth openings. An evaporator coil and evaporator fan are mounted in the first chamber. The evaporator fan moves air from the first opening, through the evaporator coil, to the second opening. A condensing coil, compressor, and compressor fan are mounted in the second chamber. The compressor fan moves air from the third opening, through the condensing coil, over the compressor, to the fourth opening. The housing thermally insulates the first chamber from both the second chamber and an exterior of the housing. The housing also seals the first chamber, such that substantially all air in the first chamber enters the first chamber through the first opening and exits the first chamber through the second opening. The housing is further adapted to automatically couple the first opening to the product storage compartment and the second opening to the duct when the housing is inserted into the vending machine.
