Abstract: A refrigerator cabinet having a metal outer shell and a plastic inner liner, containing a partition between fresh food and freezer compartments formed of a metal plate defining the fresh food compartment ceiling, a rigid expanded styrene bead thermally insulating divider mounted on the plate, and a plastic tray forming the freezing compartment floor mounted on the divider. An elongated strip of flexible polyurethane is folded lengthwise over a vertical edge of the plate so as to form a compressible, resilient air tight thermal seal between the sides and back of the plate and the adjacent liner walls regardless of changes in the gap distance between the plate and liner caused by the thermal variations of refrigerator operation or reasonable manufacturing variations.

Abstract: An anti-sweat refrigerator cabinet warming device including a secondary refrigerant loop heat transfer arrangement extending through the refrigerator cabinet to warm those portions which have a tendency to form condensate on the exterior surfaces. The secondary loop is warmed by thermal contact with the condenser loop of the refrigeration system, which thermal contact is selectively controllable by positioning of a control member to position a section of the secondary loop and the condenser loop into and out of thermal contact. This is accomplished by a clamp acting on the loop sections, operated by a manual control lever to allow the selective operation of the heat transfer device. This allows power conservation when the warming of the cabinet is not required to prevent condensate formation. The clamping device is designed to maximize the transfer of heat from the condenser loop section into the secondary loop section when the cabinet is being warmed.
