  • Patent number: 3992171
    Abstract: A forced air refrigeration system for a side by side combination refrigerator freezer wherein a single, vertical evaporator is enclosed in a vertical passageway formed between a cover panel and the rear wall of the freezer compartment. The large opening in the cover panel near the midsection of the evaporator provides an inlet from the freezer compartment into the passageway. A fan, mounted on the panel in front of the inlet opening, moves air from the freezer compartment through the opening into the middle of the evaporator. Air moved by the fan splits into two components, one moving upwardly through the top half of the evaporator and one moving downwardly through the lower half of the evaporator. After being cooled by the evaporator, the two air components exit at respective outlets formed at the upper and lower ends of the passageway. Circulation of air from the freezer compartment through the refrigerator compartment is accomplished by means of thermally controlled air ducts.
