    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 modular refrigerator system includes a modular cabinet and a machine housing. The modular cabinet comprises at least two sections that are secured to each other and collectively define an internal cavity configured to receive perishable foodstuffs or other items that may need to be refrigerated. The machine housing defines a machine compartment having a refrigeration circuit disposed therein. The refrigeration circuit has an evaporator and a condenser. The machine housing is secured to the modular cabinet and has an interface that establishes fluid communication with the internal cavity of the modular cabinet.

    Abstract: A vacuum insulated refrigerator structure being formed from a wrapper extending around a liner is provided. The liner is positioned inside of the wrapper to form a gap there between, and to form a cavity between the wrapper and the liner. An insulating thermal bridge is formed from molding one or more extruded rails to one or more corner pieces in an injection molding device. The insulating thermal bridge is coupled across the gap wherein the insulating thermal bridge includes elongated first and second channels wherein the first and second edges are inserted into the elongated first and second channels, respectively. A curable sealant is contacted to the elongated first and second channels and the cavity is at least partially filled with a porous material between the wrapper and the liner. A vacuum is formed in the cavity and the cavity is sealed to maintain the vacuum.

    Abstract: A cooking appliance includes a cooking cavity having first and second sidewalls that are spaced-apart from one another. A housing includes first and second sidewalls that are spaced-apart from one another and an upper wall. The first and second sidewalls of the housing are spaced-apart from the first and second sidewalls of the cooking cavity to define first and second side channels therebetween, respectively. A duct assembly includes first and second sidewalls spaced-apart from one another and an upper wall. The duct assembly is positioned on the upper wall of the housing and includes an interior cavity having a front opening and a rear opening. A blower assembly includes an inlet operably coupled to the rear opening of the duct assembly and is fluidically coupled to the first and second channels. The blower assembly includes an upwardly opening rear outlet having a plurality of baffles and deflectors positioned therein.
