ABSTRACT:
A refrigerator, including a cabinet having top, bottom, rear and opposing side walls that collectively define a freezer compartment and a fresh food compartment, employs a cooling system and an air plenum to deliver a cooling air flow into the freezer and fresh food compartments. The air plenum includes a variable position air damper having a first, substantially straight portion and a second arcuate portion that forms an air scoop. The air damper is slidably mounted within the air plenum between first and second positions. The variable position air damper is selectively arranged in the first position to efficiently deliver a volume of the cooling air flow into the freezer compartment, the second position to deliver the cooling airflow into the fresh food compartment or in an infinite number of intermediate positions to deliver the cooling airflow into both compartments.
