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. The cooling unit includes a heat exchanger disposed within the interior of the housing. 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 the 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. The cooling unit includes a cooling unit housing located at a rear side of the refrigerator.

Abstract: A refrigerator has a component subassembly incorporating a plurality of refrigeration components along an airflow path that extends between an inlet for colder air and an outlet for warmer air. The refrigerator further includes a noise reduction arrangement for reducing an operating noise of the refrigerator having a plurality of walls defining the airflow path. The walls include a noise absorbing material. The plurality of walls includes a plurality of external walls and a plurality of internal walls. The plurality of external walls defines an outer perimeter of the component subassembly and are oriented generally orthogonal to one another. The internal walls of the plurality of internal walls may be skewed relative to the external walls of the plurality of external walls. At least some of the walls of the plurality walls may be load-bearing walls.

Abstract: A refrigerator has a cabinet, at least one door and a plurality of refrigeration components. The cabinet defines an interior volume including at least one cooling compartment. The at least one door is carried by the cabinet and provides access to the interior volume. The plurality of refrigeration components includes a compressor, a condenser and a fan. The refrigerator additionally includes a component subassembly incorporating the plurality of refrigeration components and an airflow path extending between an inlet for colder air and an outlet for warmer air. The refrigeration components are located along the airflow path. The refrigerator further includes a noise reduction arrangement for reducing an operating noise of the refrigerator. The noise reduction arrangement including a plurality of walls defining the airflow path. The walls include a noise absorbing material. The plurality of walls includes a plurality of external walls and a plurality of internal walls.

Abstract: A cooling unit constructed in accordance with one example of the present disclosure includes an outer shell that defines an interior volume. A cooling system cools the interior volume. A temperature sensor senses a temperature within the interior volume. A heating element is disposed within the interior volume. A controller communicates with the temperature sensor and the heating element and activates the heating element based on the temperature satisfying a threshold.
