Abstract

An airflow system is provided in a refrigeration appliance that includes first and second fans. The first fan distributes first air from an evaporator of the refrigeration appliance and the second fan distributes second air from the evaporator. The airflow system has a first damper that receives the first air from the first fan and directs the first air to a first set of compartments. Additionally, the airflow system includes a second damper that receives the second air from the second fan and directs the second air to a second set of compartments. The airflow system has a housing that stores at least one of the first fan and the second fan and at least one of the first damper and the second damper.
