A refrigerator is disclosed which is provided with two separate compartments, one being a freezing compartment and the other being a fresh food compartment and with a single thermostat and damper arrangement to provide two temperature control within the refrigerator enclosure. The air distribution system includes a conduit disposed in the divider between the freezing compartment and the fresh food compartment and in which the evaporator is situated. Air inlets at the front of the refrigerator provide for the entrance of air from the fresh food and freezer compartment to this evaporator. At the rear of the refrigerator, a fan is disposed for providing for forced circulation of the air flow through the evaporator. A large portion of the air coming off the evaporator is directed through a conduit arrangement back to the freezer compartment to furnish cooling for it, with this compartment receiving approximately 90 percent of the air through the evaporator. Joined to the conduit providing cold air to the freezer is a conduit which leads down through the rearward portion of the refrigerator and discharges an air flow around a meat keeper or vegetable crisper contained in the fresh food compartment. A second conduit is also joined to the conduit supplying cooled air to the freezer, with this conduit being provided with a damper arrangement to adjustably maintain the air flow therethrough to the fresh food compartment. A thermostat is disposed adjacent the juncture of the last two mentioned conduits, with this thermostat controlling the operation of the evaporator so as to maintain a substantially uniform cooling temperature in the freezer. The temperature in the fresh food compartment, of course, may be adjustably maintained based on the setting of the aforementioned damper.
