Abstract:
1. An inerting method for preventing fire and for extinguishing fire in a compartment, comprising: supplying fresh air in a regulated manner to a compartment atmosphere as supply air and discharging exhaust air from the compartment atmosphere in a regulated manner; and supplying an extinguishing agent which is gaseous under normal conditions to the compartment atmosphere as the supply air, should a fire occur or to prevent a fire; wherein a reduced compartment pressure (p wherein a pressure difference between a compartment pressure prevailing in the compartment and an air pressure of the ambient atmosphere is further measured continuously or at predefinable times and/or upon predefinable events and the pressure difference is compared to a predefinable value to obtain a comparison between the pressure difference and the predefinable value, and wherein the total volume flow of the fresh air and/or extinguishing agent supplied to the compartment atmosphere as supply air and the volume flow of the exhaust air discharged from the compartment atmosphere is regulated as a function of the comparison between the pressure difference and the predefinable value.
