Abstract
A refrigerator includes a housing defining an interior, a freezer disposed within the interior, and a cooling unit for cooling the interior of the refrigerator. The freezer has a freezer door. At least one ventilation duct vertically extends through the freezer door. The at least one ventilation duct has a first end in communication with an upper zone of the interior of the refrigerator. An airflow path extends between a heat exchanger and a lower end of the at least one ventilation duct. A cooling fan is disposed within the interior of the refrigerator for directing a source of air across the heat exchanger, along the airflow path, through the at least one ventilation duct and into the upper zone of the interior of the refrigerator.
