초록 ▼

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.

대표청구항 ▼

A side by side combination refrigerator-freezer having an insulated cabinet defining a refrigerator compartment and an adjacent freezer compartment separated by an insulated partition wall, comprising: a refrigeration system including a single vertically disposed evaporator of the finned coil type to cool air circulated therethrough; a forced air circulation system having a vertically disposed, air passageway which includes a back wall of the freezer compartment, the vertically disposed evaporator being positioned within the air passageway so that air may pass between the fins of the evaporator; means forming an upper air outlet adjacent the upper end of the air passageway and means forming a lower air outlet adjacent the lower end of the passageway; means providing a main opening from the freezer compartment into the air passageway adjacent the midsection of the evaporator; means disposed adjacent the main opening for moving air through the midsection opening into the passageway such that a portion of the moving air may be moved upwardly across the upper portion of the evaporator and exit out the upper opening into the freezer compartment and another portion of the air may be moved downwardly across the lower portion of the evaporator and exit out the lower opening into the freezer compartment; a laterally extending air supply duct providing for air flow from the passageway into the refrigerator compartment; and a laterally extending air return duct providing for air flow from the refrigerator compartment into the freezer compartment.
