Abstract: An air duct is provided for a refrigerator having an enclosure and a refrigeration system with a fan for generating a cooling airflow. The air duct includes an air inlet fluidly couplable to and arranged for receiving the cooling airflow from the refrigeration system. An air outlet is downstream of the air inlet, and arranged to direct the cooling airflow from the refrigeration system into the enclosure in a first direction. A diverter is located between the air inlet and the air outlet and configured to divert a portion of the cooling airflow into the enclosure in a second direction different to the first direction.
