Abstract

The invention relates to a storage compartment (6) and an evaporator compartment (5) communicating with said storage compartment (6) via a cold air passage (14) and a hot air passage (9) and comprising an evaporator (8) and a defrost heater (15). Said defrost heater (15), in a region adjacent to the hot air passage (9), has a higher heating power density than in a region adjacent to the cold air passage (10).
