ROTARY AIR DAMPER WITH SHUTOFF BYPASS

摘要

A damper assembly for use in a refrigeration system having a temperature adjustable compartment is presented. The damper assembly comprises a housing and a damper door assembly rotatable therein. The housing includes a flange that cooperates with a semicircular flange of the damper door assembly to form two air flow channels in the housing. When the damper door is open, chilled air from the freezer compartment is allowed to circulate through the damper assembly and through the compartment to provide a quick chill mode of operation. The damper door is also rotatable to a closed position that allows air to circulate within the damper assembly and the compartment. A heater may be included to provide a quick defrost mode of operation.
