Title
(EN) BUILDING MANAGEMENT SYSTEM, CONTROLLER AND METHOD FOR FILTERING A FLUID
(FR) SYSTÈME DE GESTION DE BÂTIMENT, DISPOSITIF DE COMMANDE ET PROCÉDÉ DE FILTRATION DE FLUIDE
Abstract
(EN)
A building management system (BMS) for filtering a fluid within a building is shown. The system includes one or more sensors configured to measure one or more characteristics of a first fluid within an air duct of the BMS and measure one or more characteristics of a second fluid after the second fluid has been filtered. The system further includes a pollutant management system configured to receive data from the one or more sensors and control a filtration process. The filtration process selects a filter of a plurality of filters based on a level of the one or more characteristics of the first fluid and the one or more characteristics of the second fluid.
(FR)
L'invention concerne un système de gestion d'un bâtiment (BMS) permettant de filtrer un fluide à l'intérieur du bâtiment. Le système comprend un ou plusieurs capteurs conçus pour mesurer une ou plusieurs caractéristiques d'un premier fluide à l'intérieur d'un conduit d'air du BMS, et pour mesurer une ou plusieurs caractéristiques d'un second fluide après filtration du second fluide. Le système comprend en outre un système de gestion des polluants, configuré pour recevoir des données à partir du ou des capteurs, et pour commander un traitement de filtration. Le traitement de filtration sélectionne un filtre parmi une pluralité de filtres, en fonction d'un niveau de la ou des caractéristiques du premier fluide et de la ou des caractéristiques du second fluide.
