Abstract: A refrigeration unit includes a cabinet, a door coupled to the cabinet, at least one gasket coupled to the door, and a heat loop conduit. The cabinet includes a front perimeter that surrounds an opening to a storage compartment within the cabinet. The door is operable between an open position to provide access to the storage compartment and a closed position to conceal the opening to the storage compartment. The at least one gasket is configured to be compressed between the door and the front perimeter of the cabinet in the closed position of the door. The heat loop conduit has a first conduit portion that extends around a majority of the opening along the front perimeter of the cabinet and a second conduit portion that extends around the majority of the opening along the front perimeter of the cabinet.

Abstract: A method for manufacturing a vacuum insulated structure includes adhering a trim breaker to a wrapper and a liner via an adhesive to define an insulated structure. The insulated structure is positioned within an evacuation chamber proximate to a first heater and a second heater. The insulated structure and the evacuation chamber are heated via the first heater and the second heater. The evacuation chamber is evacuated via a first vacuum pump, and the insulated structure is evacuated via a second vacuum pump.

Abstract: A filling system for a vacuum insulated structure is provided having a powder processor including a hopper having an inner hopper wall and an outer hopper wall. The filling system also includes a vacuum insulated structure having a liner positioned inside a wrapper, a trim breaker coupling an outer liner edge and an outer wrapper edge to form a shell defining an internal cavity with at least one gas permeable feature positioned in the internal cavity configured to help apply a vacuum. A loading port is positioned on a surface of the shell. The powder processor loads the shell with a heated and at least partially degassed vacuum insulation material through the loading port while a vacuum is applied to the shell through the at least one gas permeable feature.

Abstract: An appliance includes an outer wrapper having a plurality of walls that define an external surface and an inner liner. A trim breaker seals the outer wrapper to the inner liner to define an insulation space. A vacuum port is disposed on the external surface of the outer wrapper. A channel is in fluid communication with the vacuum port and extends along at least one of the plurality of walls of the outer wrapper. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed along the channel such that air can be drawn from the insulation space past the filter media, into the channel, and through each vacuum port.
