Title
(EN) SYSTEM FOR MIXING AIR
(FR) SYSTÈME POUR MÉLANGER DE L'AIR
Abstract
(EN) The description relates to a system for mixing air in an environment comprising an air mixer comprisiung an adjustable speed motor and a helical-centrifugal impeller, a sensor configured to measure a parameter indicating the environmental conditions, and a control module connected to said air mixer and to said sensor. The control module is contifured to receive at its input a signal from the sensor indicating the value of the parameter and to output to the mixer a control signal for adjusting the speed of the motor as a function of the value of the parameter measured by the sensor. The impeller comprises first and second helical portions, each arranged at a respective end of a shaft which connects the impeller to the motor and comprising at least two blades, and centrifugal blades arranged in a radial position with respect to the helical portions and connecting the ends of the blades of the helical portions in a direction perpendicular thereto.
(FR) L'invention concerne un système pour mélanger de l'air dans un environnement comprenant un mélangeur d'air comprenant un moteur à vitesse réglable et une roue à aubes centrifuge hélicoïdale, un capteur configuré pour mesurer un paramètre indiquant les conditions environnementales, et un module de commande connecté audit mélangeur d'air et audit capteur. Le module de commande est configuré pour recevoir, au niveau de son entrée, un signal provenant du capteur indiquant la valeur du paramètre et pour délivrer, vers le mélangeur, un signal de commande pour régler la vitesse du moteur en fonction de la valeur du paramètre mesuré par le capteur. La roue à aubes comprend des première et seconde parties hélicoïdales, agencées chacune à une extrémité respective d'un arbre qui relie la roue à aubes au moteur et comprenant au moins deux pales, et des pales centrifuges agencées dans une position radiale par rapport aux parties hélicoïdales et reliant les extrémités des pales des parties hélicoïdales dans une direction perpendiculaire à celles-ci.
