An opening (54) is arranged in the intermediate wall (44), through which opening an impeller (56) sucks in air from the space and blows the air out into the chamber (52), the cross sectional area of which decreasing in vertical direction so that the air is evenly distributed along the evaporator (38) before the air in sidewards direction passes through the evaporator out into the space along the rear wall, from where the air circulates further on through the space between shelves located therein back to the opening (54).
