Air flow design for controlling temperature in a refrigerator compartment

A refrigerator comprising:

• a cabinet having a first temperature controlled compartment and a second temperature controlled compartment;
• an electronic control;
• a user interface accessible to a user comprising a normal operation selection and a cooling operation selection;
• a pair of air return ducts between the temperature controlled compartments;
• a normal operation, wherein the pair of air return ducts return relatively warm air from the first to the second temperature controlled compartment;
• a cooling operation, wherein when the user selects the cooling operation on the user interface, one of the pair of air return ducts is switchable between an air return and air supply duct to supply air to the first temperature controlled compartment from the second temperature controlled compartment.

A method for controlling temperature in a refrigerator comprising:

• providing a cabinet having a freezer compartment and a refrigerator compartment and first and second air pathways between the freezer compartment and the refrigerator compartment with a fan disposed within at least one of the first and second air pathways;
• providing a user interface accessible to a user in electronic communication with an intelligent control;
• returning relatively warm air to the freezer compartment from the refrigerator compartment through both the first and second air pathways;
• activating a cooling operation on the user interface;
• reversing direction of air flow in the first or second air pathway for supplying cold air to the refrigerator compartment from the freezer compartment.
