La chambre de refroidissement est située au niveau de la partie inférieure dans le corps (100), occupe l'espace inférieur dans le corps (100), et permet à un espace pour un compartiment de compresseur. La chambre de congélation et une chambre de réfrigération sont respectivement pourvues d'un ventilateur séparé pour l'alimentation en air, de telle sorte que les écoulements d'air de refroidissement dans différents conduits n'interfèrent pas l'un avec l'autre, empêchant ainsi une interférence de température entre la chambre de congélation et la chambre de réfrigération.
