Abstract

Ce système d'extraction d'air comprend un ventilateur, des bouches d'extraction d'air, et une unité de contrôle du ventilateur, adaptée pour piloter la vitesse de rotation du ventilateur selon une loi de fonctionnement donnant la pression (P) fournie par le ventilateur en fonction du débit (Q) du système d'extraction d'air. L'unité de contrôle est adaptée pour calculer la loi de fonctionnement selon deux courbes affines (C1, C2) passant par au moins trois points incluant un point maximal (pM) défini par un débit maximal (Qmax) nécessaire au fonctionnement du système, spécifié par un utilisateur via une interface de contrôle de l'unité de contrôle, et une pression maximale (Pmax) devant être fournie par le ventilateur pour le débit maximal, un point minimal (pm) défini par une pression minimale (Pmin) fixe devant être fournie par le ventilateur et le débit minimal (Qmin) devant être fourni par le système d'extraction, ce débit minimal (Qmin) étant calculé par l'unité de contrôle à partir de la valeur du débit maximal (Qmax), un point intermédiaire (pi) défini par une pression (Pint) et un débit (Qint) intermédiaires compris entre les valeurs de pression et débit minimales et maximales, la pression intermédiaire (Pint) et le débit intermédiaire (Qint) étant calculés par l'unité de contrôle à partir des valeurs de pression et de débit des points maximal (pM) et minimal (pm).This air extraction system includes a fan, air extraction vents, and a fan control unit, adapted to control the fan's rotation speed according to an operating law giving the pressure (P) supplied. by the fan according to the flow (Q) of the air extraction system. The control unit is suitable for calculating the operating law according to two affine curves (C1, C2) passing through at least three points including a maximum point (pM) defined by a maximum flow rate (Qmax) necessary for the operation of the system, specified by a user via a control interface of the control unit, and a maximum pressure (Pmax) to be supplied by the ventilator for the maximum flow, a minimum point (pm) defined by a fixed minimum pressure (Pmin) to be supplied by the fan and the minimum flow rate (Qmin) to be supplied by the extraction system, this minimum flow rate (Qmin) being calculated by the control unit from the value of the maximum flow rate (Qmax), an intermediate point (pi) defined by an intermediate pressure (Pint) and flow (Qint) between the minimum and maximum pressure and flow values, the intermediate pressure (Pint) and the intermediate flow (Qint) being calculated by the control unit from the vale Maximum (pM) and minimum (pm) point pressure and flow rate.
