Title
(EN) REFRIGERATOR WITH DYNAMIC MULTI-ZONE ANTI-SWEAT HEATING SYSTEM
(FR) RÉFRIGÉRATEUR AVEC SYSTÈME DE CHAUFFAGE DYNAMIQUE MULTIZONE ANTI-CONDENSATION
Abstract
(EN) A dynamic multi-zone anti-sweat heating system may be used in a refrigerator to reduce moisture on various surfaces of the refrigerator. Moreover, in some instances, the determination of when moisture is present and/or absent from a surface may be made based at least in part on detection of the presence or absence of an elevated thermal load on the surface while a heater is activated.
(FR) L'invention concerne un système de chauffage dynamique multizone anti-condensation pouvant être utilisé dans un réfrigérateur pour réduire l'humidité sur diverses surfaces du réfrigérateur. De plus, dans certains cas, la détermination du moment où l'humidité est présente et/ou absente d'une surface peut être réalisée sur la base, au moins en partie, de la détection de la présence ou de l'absence d'une charge thermique élevée sur la surface lorsqu'un appareil de chauffage est activé.
