Abstract
A refrigerator includes an evaporator, a first fan, a first duct, a second fan, a second duct, and a plate. The first duct is mounted between the evaporator and the first fan. The first fan moves air from the first duct into a first zone. The second fan moves air from the second duct into a second zone. The plate is mounted between the evaporator and the second duct. The plate includes a plate aperture wall that defines a duct aperture formed through the plate. A first aperture of the second duct is adjacent the second fan. A second aperture of the second duct is positioned to encompass the duct aperture. A center of the duct aperture is positioned a distance from a center of the evaporator measured in a first direction. The distance is between 0% and 40% of a total length of the evaporator in the first direction.
