Abstract

Un système CVC comprend un moteur souffleur et un moteur dentraînement à vitesse variable. Le moteur dentraînement à vitesse variable est conçu pour recevoir une alimentation secteur et la fournir au moteur souffleur sous forme dalimentation modulée. Le moteur souffleur est conçu pour produire un débit dair en réponse à lalimentation modulée. Une commande dunité est configurée pour outrepasser le moteur dentraînement à vitesse variable pour fournir lalimentation secteur directement au moteur souffleur si un débit dair mesuré est plus faible quune valeur prédéterminée.
