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.
