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.

Split air flow system

A refrigerator includes an evaporator, a first fan, a first duct, a first return duct, a second fan, a second duct, and a second return duct. A first temperature sensor measures a first temperature in a first enclosed space. A second temperature sensor measures a second temperature in a second enclosed space. The first duct is mounted between the evaporator and the first enclosed space to receive air from the first duct and move it into the first enclosed space. The first return duct is mounted between the first enclosed space and the evaporator. The second duct is mounted between the evaporator and the second enclosed space to receive air from the second duct and move it into the second enclosed space. The second return duct is mounted between the second enclosed space and the evaporator. A refrigerator controller controls the evaporator and independent operation of both fans.
