    Abstract: A method of measuring pressure includes the steps of (1) providing a vacuum cabinet with a storage compartment and an insulating space, and three temperature sensors; (2) sensing a first temperature level of an interior wall of the storage compartment; (3) sensing an ambient temperature level within the storage compartment; (4) sensing a second temperature level of an exterior wall of the storage compartment; (5) calculating an overall heat transfer coefficient (Q) using the ambient temperature level, the first temperature level, and a convective heat transfer coefficient for the interior wall of the storage compartment; (6) calculating a temperature differential between the second and first temperature levels; (7) determining a conductivity level (K) using the temperature differential, the overall heat transfer coefficient (Q) and a thickness of the insulating space; and (8) determining a pressure level (P) within the insulating space using the conductivity level (K).

    Abstract: A vacuum insulated door for an appliance includes an outer wrapper that defines an evacuation port. An inner liner is coupled to the outer wrapper defining an insulating cavity therebetween. A base is coupled to the outer wrapper adjacent to the evacuation port. A servicing tube has a connecting end and a servicing end. The servicing tube is in fluid communication with the insulating cavity via the evacuation port. The connecting end is coupled to the base. A handle has first and second ends coupled to the outer wrapper and a center portion therebetween spaced-apart from the outer wrapper. The first end is coupled to the outer wrapper proximate the evacuation port. The servicing tube extends along an inner surface of the handle.

    Abstract: An appliance includes a panel having a raised landing outwardly extending from a first surface of the panel. A vacuum port is disposed on the raised landing. A system of channels is disposed over the first surface of the panel and outwardly extends therefrom. The system of channels substantially covers the first surface of the panel. The first surface of the panel is covered with a filter member that covers the system of channels. The raised landing, and vacuum port thereof, is fluidically coupled to the system of channels at multiple connecting locations.
