Abstract

L'invention porte sur la climatisation d'air et la commande de pression d'un bâtiment à étages multiples, de sorte que de l'air de remplacement soit fourni dans un appartement (13) à travers une cage d'escalier (6). L'air de remplacement rentre dans la cage d'escalier (6) à travers un tuyau d'entrée d'air (2) sur le toit du bâtiment à l'aide d'un ventilateur (3). Le ventilateur (3) accroît la pression de l'air de remplacement, cette pression provoquant un écoulement d'air vers le bas dans la totalité du tuyau vertical s'étendant vers le bas (7), lequel écoulement d'air se décharge à travers des diffuseurs de ventilation (22) dans l'espace de la cage d'escalier (6). A l'aide du ventilateur (3) et de la commande de celui-ci, une pression qui est une valeur prédéfinie supérieure à la pression atmosphérique de l'air ambiant (12) est délivrée dans la cage d'escalier (6) par un dispositif de mesure de pression différentielle (9) ou par des différences de manomètres (10) et (11). L'air de remplacement peut s'écouler à partir de la cage d'escalier (6) dans l'appartement (13) par l'intermédiaire d'une vanne (16), qui est sans ou avec coupe-feu, et qui présente un orifice constant variable, et qui est disposée dans une paroi de séparation (14). La surpression existant dans l'appartement (13) empêche de l'air contaminé d'entrer dans l'appartement (13). La surpression dans la cage d'escalier (6) empêche l'air ambiant contaminé d'entrer dans la cage d'escalier (6) lors de l'ouverture d'une porte d'entrée (20). Un appareil d'humidificateur, et, éventuellement, un appareil de séchage d'air, peuvent être reliés en série au ventilateur (3). Le condensat s'accumule sur le fond (3) du tuyau vertical (4) et peut en être retiré par l'intermédiaire d'une vanne (31). Il est essayé de maintenir une température constante dans la cage d'escalier (6).
