Abstract

L’invention a pour objet un procédé de régulation de la pression fournie par un ventilateur à vitesse de rotation ajustable dans une installation de ventilation comprenant en outre: - N gaines d’air, chacune raccordée à un piquage d’un caisson central comportant ledit ventilateur; et - N régulateurs de débit à ouverture de passage réglable, associés chacun à une gaine d’air. Le procédé comprend une modulation (101) d’une ouverture de chaque régulateur de débit pour qu’un débit le traversant tende vers une consigne de débit par gaine, pour une pression courante fournie par le ventilateur ; et, en parallèle de la modulation (101) : - la détermination (102), parmi les N régulateurs de débit, d’un régulateur de référence qui présente la plus grande ouverture de passage ; - l’ajustement (103) de la pression fournie par le ventilateur pour tendre à obtenir, pour ce régulateur de référence, une ouverture maximum de passage prédéfinie. Figure pour l’abrégé : Fig. 4The subject of the invention is a method for regulating the pressure supplied by a fan with adjustable rotation speed in a ventilation installation further comprising: - N air ducts, each connected to a tap of a central box comprising said fan; and - N flow regulators with adjustable passage opening, each associated with an air duct. The method comprises a modulation (101) of an opening of each flow regulator so that a flow passing through it tends towards a flow setpoint per duct, for a current pressure supplied by the fan; and, in parallel with the modulation (101): - the determination (102), among the N flow regulators, of a reference regulator which has the largest passage opening; - adjustment (103) of the pressure supplied by the fan to tend to obtain, for this reference regulator, a predefined maximum passage opening.
