Abstract

La présente invention concerne un procédé et un dispositif de commande d'un dispositif de climatisation et un dispositif de climatisation. Une sortie d'air est agencée au niveau d'une unité intérieure du dispositif de climatisation. Un canal d'air en communication avec la sortie d'air est doté en son sein d'un ventilateur et d'une unité de purification utilisée pour purifier une sortie d'écoulement d'air provenant du ventilateur. La sortie d'air est en outre dotée d'un premier capteur utilisé pour détecter une vitesse d'air. Le procédé consiste : à commander un premier capteur pour détecter une vitesse d'air de sortie d'un écoulement d'air après que l'écoulement d'air a traversé une unité de purification ; à déterminer, pour l'unité de purification, et en fonction d'une différence entre la vitesse d'air de sortie et une vitesse d'air de référence, une quantité d'air ou une valeur de perte de vitesse d'air ; et à régler une vitesse de rotation du ventilateur en fonction de la quantité d'air ou de la valeur de perte de vitesse d'air. Le procédé permet de régler automatiquement une vitesse de rotation d'un ventilateur en fonction d'une quantité d'air ou d'une valeur de perte de vitesse d'air, ce qui permet de régler la quantité d'air purifié, ce qui garantit l'efficacité et la performance de purification. De plus, la vitesse de rotation du ventilateur change en fonction de la valeur de perte, ce qui permet d'empêcher une consommation d'énergie élevée suite à une rotation continue du ventilateur à une vitesse supérieure et de réduire efficacement la consommation d'énergie.
