ABSTRACT:
A refrigerator includes at least a first compartment cooled to a first temperature and a second compartment cooled to a second temperature, and a multiplex damper system disposed in a cooling-air passage so as to selectively direct the cooling-air flow from the refrigeration apparatus to the compartments. The multiplex damper system comprises a single movable control damper mounted in the cooling-air passage and a drive control system responsive to the cooling demands of the respective compartments and that is coupled to the single control damper so as to selectively dispose the control damper in a plurality of respective air flow positions. The range of air flow positions includes a first compartment-only air flow position, a second compartment-only air flow position, and at least one divided-flow position in which cooling air flow is proportionally directed into both the first and the second compartments.
