Abstract

La présente invention concerne un procédé de contrôle de la durée de vie d'un tamis filtrant pour purificateur d'air, comprenant les étapes suivantes : mise sous tension et lecture d'une valeur moyenne de puissance et/ou d'une valeur moyenne de vitesse de rotation ; évaluation de la quantité de purification cumulée du purificateur d'air ; après l'évaluation, lecture à nouveau de la valeur moyenne de puissance et/ou de la valeur moyenne de vitesse de rotation d'un moteur ; calcul du taux de changement de puissance et du taux de changement de vitesse de rotation du purificateur d'air ; démarrage du purificateur d'air et maintien du purificateur d'air en fonctionnement continu pendant 24 heures, et ensuite lecture de la valeur moyenne de puissance et/ou de la valeur moyenne de vitesse de rotation, et calcul de la plage de la valeur d'une cible de puissance et/ou de la plage de la valeur d'une cible de vitesse de rotation selon une formule de taux de changement de puissance et une formule de taux de changement de vitesse de rotation ; et lecture d'une pluralité de groupes de valeurs de puissance et détermination du fait que le tamis filtrant atteint la fin de sa durée de vie si les valeurs de puissance qui sont lues plusieurs fois en 48 à 96 heures sont toutes dans la plage de la valeur de la cible de puissance, et/ou lecture d'une pluralité de groupes de valeurs de vitesse de rotation et determination du fait qu'un tamis filtrant atteint la fin de sa durée de vie si les valeurs de vitesse de rotation qui sont lues plusieurs fois en 48 à 96 heures sont toutes dans la plage de la valeur de la cible de vitesse de rotation. Le procédé peut surveiller la durée de vie du tamis filtrant et réduire le coût d'utilisation du tamis filtrant.
