Abstract

L'invention porte sur un appareil et sur un procédé pour commander le chauffage d'une chaudière. Le procédé pour commander le chauffage d'une chaudière met en œuvre : la fourniture d'une première quantité de chaleur prédéfinie durant le chauffage et la détection de la température d'une eau d'alimentation et d'une eau de retour afin de déterminer un débit d'écoulement de circulation de chauffage ; et la commande, sur la base du débit d'écoulement de circulation de chauffage déterminé, de la quantité de chaleur fournie, de sorte que la température de l'eau de retour est accrue et maintenue à une température constante. Le procédé pour commander le chauffage de la chaudière met de plus en œuvre : la détermination du fait que la température constante est ou non égale à une température établie d'eau de retour prédéfinie, et la re-détermination d'un débit d'écoulement de circulation de chauffage lorsque la température constante est différente de la température établie d'eau de retour prédéfinie ; et la compensation, sur la base du débit d'écoulement de circulation de chauffage re-déterminé, de la quantité de chaleur, de sorte que l'eau de retour soit maintenue à la température établie d'eau de retour. Par conséquent, le nombre de fois où la chaudière est démarrée/arrêtée durant le chauffage peut être minimisé, de façon à réduire le bruit et à augmenter la durée de vie de la chaudière. Également, le temps de retard pour le chauffage peut être réduit, de façon à réduire l'insatisfaction des clients
