Abstract

La présente invention concerne un procédé et un système (1) fonctionnant selon ledit procédé de ventilation d'au moins un poste de travail (2) qui est soumis à des charges de pollution particulières. La présente invention concerne en outre un système (1) qui présente une consommation d'énergie relativement faible mais fournit un degré élevé de pureté de qualité de l'air, satisfaisant aux exigences strictes de la réglementation TRBA, le flux d'air (5', 5") présentant un profil caractéristique, dont le flux d'air est plus fort aux bords qu'à l'intérieur du flux d'air. L'air d'alimentation n'est pas prélevé dans l'espace extérieur, mais plutôt depuis le même espace (3) dans lequel l'au moins un poste de travail (2) est situé. En outre, les éléments de ventilation individuels (4) peuvent être commandés individuellement et mis en réseau pour fonctionnement, dans la mesure où cela s'avère nécessaire compte tenu des conditions extérieures données. Les filtres dits HEPA et le rayonnement UV interagissent avantageusement dans un élément de ventilation spécial (4) qui, entre autres, facilite significativement le remplacement du filtre HEPA.
