Abstract
An appliance that includes a vacuum insulated cabinet structure having an exterior wall and an interior wall with a vacuum therebetween that forms at least the back wall, bottom, right side, left side, and top of the appliance; and a dual cooling system that includes at least one vapor compression system portion configured to operate during a pull down mode and a thermoelectric portion configured to operate in a steady-state mode without the vapor compression system operating while providing sufficient cooling to offset the steady-state heat load of the appliance.
