Title
(EN) HEATING, VENTILATION, AIR-CONDITIONING SYSTEM AND METHOD TO OPERATE SUCH SYSTEM
(FR) SYSTÈME DE CHAUFFAGE, DE VENTILATION, DE CLIMATISATION ET PROCÉDÉ D'EXPLOITATION DUDIT SYSTÈME
Abstract
(EN) The present subject matter relates to a method comprising generating a first signal (S1, S1') based on deviation of a parameter of at least one fluid (F1, F2) of a heat exchanger (3) from a predefined set-point value, generating a second signal (S2, S2') based on deviation of at least one parameter of at least one fluid (F1, F2) of the heat exchanger (3) from corresponding predefined set-point values, selecting one signal (S3, S3') from the first signal (S1, S1') and the second signal (S2, S2'), and actuating a control valve (5) based on the selected signal (S3, S3'). The present subject matter also relates to a system (1, 1') based on the method according to the present subject matter.
(FR) L'invention concerne un procédé consistant à générer un premier signal (S1, S1') en fonction d'un écart d'un paramètre d'au moins un fluide (F1, F2) d'un échangeur de chaleur (3) par rapport à une valeur de consigne prédéfinie, à générer un second signal (S2, S2') en fonction d'un écart d'au moins un paramètre d'au moins un fluide (F1, F2) de l'échangeur de chaleur (3) par rapport à des valeurs de consigne prédéfinies correspondantes, à sélectionner un signal (S3, S3') parmi le premier signal (S1, S1') et le second signal (S2, S2'), et à actionner une vanne de commande (5) en fonction du signal sélectionné (S3, S3'). L'invention concerne également un système (1, 1') basé sur le procédé selon la présente invention.
