Ventilation system for ventilating a fire compartment in a building

摘要

The present invention relates to a relatively inexpensive ventilation system (1) for ventilating a fire compartment in a building with several fire compartments, separated by fire partitions (2), comprising: - a ventilation fan (3) for supplying and/or discharging of air; - a measuring system for detecting a fire; - ventilation fan control means for controlling the ventilation fan (3) adapted to shut down the ventilation fan (3) when a fire is detected; - a compartment through-passage (4) for passing the air through a fire partition (2) to or from the ventilation fan (3); - a fire-resistant sealing ring (5), around the compartment through-passage (4), at the location of the fire partition (2). The present invention also relates to a method for controlling the ventilation fan (3) of such a ventilation system.
