Abstract

La présente invention concerne un réfrigérateur sans givre offrant la possibilité de convertir le compartiment congélateur en compartiment pour aliments frais. Ce réfrigérateur comprend un compartiment congélateur (1), un compartiment pour aliments frais (2), qui présente un bac à légumes (3), un compresseur (4), un évaporateur (6), ainsi qu'un ventilateur (7), qui permet d'assurer une circulation d'air frais dans les compartiments du réfrigérateur. Un système de commande permet de commander la quantité d'air frais circulant dans le compartiment congélateur (1) et dans le compartiment pour aliments frais (2).
