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.
L'invention concerne un ensemble clapet destiné à un système de réfrigération qui comprend un compartiment ajustable en température. L'ensemble clapet selon l'invention comprend un boîtier dans lequel peut tourner un ensemble volet de clapet. Le boîtier comprend une joue qui coopère avec une joue semi-circulaire de l'ensemble volet de clapet afin de former deux conduits de circulation d'air dans le boîtier. Lorsque le volet de clapet est ouvert, de l'air réfrigéré provenant du compartiment congélateur peut circuler à travers l'ensemble clapet et à travers le compartiment, fournissant ainsi un mode de réfrigération rapide. Le volet de clapet peut également pivoter dans une position fermée qui permet à l'air de circuler à l'intérieur de l'ensemble clapet et du compartiment. Il est également possible d'intégrer un élément de chauffage pour disposer d'un mode de dégivrage rapide.
