Abstract

Le meuble-présentoir réfrigéré comporte un conduit d'air 22 s'étendant autour d'une boîte à marchandises et contenant un ventilateur 24 et un élément refroidisseur 25, le conduit comportant d'un côté, une ouverture d'aspiration et, de l'autre, une ouverture de refoulement munie d'aubes de guidage 28 qui dirigent l'air froid au-dessus des marchandises 21 vers l'ouverture d'aspiration. Lors du dégivrage, l'élément refroidisseur 25 est arrêté et le sens de circulation de l'air dans le conduit est inversé, de l'air ambiant étant aspiré dans le conduit 22 et l'air refoulé hors du conduit étant guidé par des organes de guidage 29 à l'écart du trajet de circulation normal et des marchandises.The refrigerated display cabinet has an air duct 22 extending around a cargo box and containing a fan 24 and a cooling element 25, the duct having on one side a suction opening and, 'another, a discharge opening provided with guide vanes 28 which direct the cold air above the goods 21 towards the suction opening. During defrosting, the cooling element 25 is stopped and the direction of air circulation in the duct is reversed, ambient air being drawn into duct 22 and the air discharged from the duct being guided by members. guide 29 away from the normal traffic path and goods.
