Abstract
Air flow designs for controlling the temperature in a temperature controlled compartment in a refrigerator are disclosed. One configuration includes a refrigerator with a cabinet having a freezer compartment and refrigerator compartment. The refrigerator may be configured with a first air return pathway between the refrigerator compartment and the freezer compartment for returning relatively warm air from the refrigerator compartment to the freezer compartment and a second air return pathway between the refrigerator compartment and the freezer compartment. A fan may be associated with the first or second air return pathway, that when activated the first or second air return pathway acts as an air supply pathway to supply cold air from the freezer compartment to the refrigerator compartment.
