Abstract: The present invention relates to a system as well as a method for extinguishing fire in an enclosed room (6) in which the enclosed room (6) is flooded with extinguishing gas at least until an extinguishing gas concentration capable of providing an extinguishing effect (a) is set in the flood zone. In order to achieve the realizing of a maximum extinguishing gas concentration (b) as quickly as possible without the flooding of the room (6) thereby posing a danger to people, it is inventively provided for the flooding of the enclosed room (6) to be divided into a pre-flooding phase and a main flooding phase subsequent thereto. The pre-flooding phase corresponds to an interval of time between the time (t1) the alarming starts to warn people of impending danger and a predefined time (t2). The main flooding phase corresponds to an interval of time between the predefined time (t2) and the time (t4) at which a maximum extinguishing gas concentration (b) is reached. The enclosed room (6) is flooded such that during the entire pre-flooding phase, the concentration of extinguishing gas in the enclosed room (6) does not exceed a predefined or predefinable value for the extinguishing gas employed which is below the critical NOAEL value.

Abstract: The present invention relates to a gas extinguishing system for a predefined protected area, particularly small-parts storage systems, wherein the gas extinguishing system comprises an inert gas source and a diffuser system fluidly connected to the inert gas source by a tubing system. The diffuser system comprises a diffuser tube having a plurality of drill holes provided in the surface of the diffuser tube and a pressure reducer allocated to the diffuser tube. In order to be able to achieve non-interactiveness with respect to the diffuser system from the standpoint of the design of the gas extinguishing system, the inventive provides for designing the diffuser system such that a primary baffle pressure measured in absolute bar is at least twice as high as the internal pressure of the diffuser tube during the flooding period dimensioned for the protected area and that the internal pressure of the diffuser tube during the dimensioned flooding period is at a maximum of 2 bar absolute.
