Abstract

L'invention porte sur un système de commande réparti intelligent pour mettre en œuvre un fonctionnement à économie d'énergie d'un dispositif de système de chauffage et de climatisation dans un bâtiment moderne. L'ensemble de système de commande réparti comprend des boucles de commande à deux étages, à savoir une boucle de commande centrale et une boucle de commande régionale. Une armoire de commande centrale envoie une instruction de commande à un dispositif de climatisation central par l'intermédiaire d'un bus maître, de façon à former la boucle de commande centrale. Un dispositif de commande régional dans chaque région règle, par l'intermédiaire d'un répéteur de communication connecté de façon correspondante, l'état de travail d'un dispositif d'exécution de climatisation terminal à l'aide de multiples instructions de commande régionales délivrées en sortie à partir d'un bus d'exécuteur, de façon à former la boucle de commande régionale. Ce produit de système peut mettre en œuvre, par l'intermédiaire d'une commande de fonctionnement à échange à points multiples entre des utilisateurs et le bâtiment, un réglage systématique du fonctionnement à économie d'énergie, par exemple par une commande à division de régions et dynamique dans le temps de charges de chauffage et de climatisation pour le bâtiment, une faible consommation d'énergie dans une zone non fréquentée, un fonctionnement à conversion de fréquence du dispositif de climatisation central, et une réponse de compensation de climat du système.
