Abstract (en)
[origin: WO0202994A1] The invention concerns a system for controlling the frontal speed of a set of ventilating air extracting equipment (1, 2, 3, 4), in particular from laboratory hoods, inside premises. Each hood is connected to ventilating air extracting means (5, 6) and comprises means for regulating (10, 11, 12, 13) the frontal air speed, means for controlling the extracted air flow rate (18, 19, 20, 21, 22, 23, 24, 25, 26), means for measuring the extracted air flow, and means for measuring the frontal air speed (14, 15, 16,17). Said system further comprises: a local communication network (38) whereto the respective regulating means (10, 11, 12, 13) of said hoods are connected as slave regulators; a master regulator (8) connected to said local communication network and adapted to provide a gateway between said slave regulating means (10, 11, 12, 13) and remote control means (35, 36, 37), and to collect and add the extracted air measurements on each ventilating air extracting equipment.
