Abstract:
(EN) The present invention relates to an air curtain device for realising an air curtain, with in use a substantial vertical air flow, and a method for providing such air curtain. The air curtain device according to the invention comprises: - a housing substantially extending along an opening in a wall and comprising air displacing means; - at least one air inlet for supplying air to the housing; - at least one primary outflow opening configured for achieving a primary air curtain with a primary height, a primary length, and a primary width, the primary outflow opening extending substantially parallel to the opening at a certain distance thereof; and - at least one secondary outflow opening configured for achieving at least one secondary air curtain substantially perpendicular to the plane defined by the opening such that it substantially closes a gap resulting from providing the air curtain at the certain distance of the opening in the wall and in use provided at or close to an end of the primary air curtain, such that in use in a horizontal plane an L-shaped or U-shaped air curtain is achieved.
(FR) La présente invention concerne un dispositif de rideau d'air permettant de réaliser un rideau d'air avec, en cours d'utilisation, un flux d'air vertical important et un procédé de fourniture d'un tel rideau d'air. Le dispositif de rideau d'air selon l'invention comprend : — un logement s'étendant sensiblement le long d'une ouverture dans un mur et comprenant un moyen de déplacement d'air; — au moins une entrée d'air destinée à alimenter de l'air au logement; — au moins une ouverture d'écoulement primaire conçue pour réaliser un rideau d'air primaire avec une hauteur primaire, une longueur primaire, et une largeur primaire, l'ouverture d'écoulement primaire s'étendant sensiblement parallèle à l'ouverture à une certaine distance de celle-ci; et — au moins une ouverture d'écoulement secondaire conçue pour réaliser au moins un rideau d'air secondaire sensiblement perpendiculaire au plan défini par l'ouverture de telle sorte qu'il ferme sensiblement un écartement résultant de la fourniture du rideau d'air à la certaine distance de l'ouverture dans le mur et, lors de sa mise en oeuvre, se trouve au niveau ou près d'une extrémité du rideau d'air primaire, de telle sorte que, lors de sa mise en oeuvre dans un plan horizontal, on obtient un rideau d'air en forme de L ou en forme de U.
