Abstract

Die Erfindung betriff ein Verfahren zur Regelung eines Luftdrucks in einem Raum (1), der mittels ihn im Wesentlichen vollständig umschließender, gasundurchlässiger Raumbegrenzungselemente von einem Außenbereich abgetrennt ist, wobei dem Raum (1) durch mindestens einen Zuluftkanal (2) Zuluft zugeführt und aus dem Raum (1) durch mindestens einen Abluftkanal (3) Abluft abgeführt wird, wobei der Luftdruck in dem Raum (1) mittels eines ersten Reglers (12), der vorzugsweise zur Regelung kleiner Schwankungen des Luftdrucks geeignet ist, so geregelt wird, dass eine Luftdruckdifferenz zwischen dem Raum (1) und dem Außenbereich stets kleiner Null ist, wobei in einem in dem Raum (1) eintretenden Brandfall ein Löschmittel in den Raum (1) eingeleitet wird.The invention relates to a method for controlling an air pressure in a room (1), which is separated by means of him substantially completely enclosing, gas-impermeable Raumbegrenzungselemente of an outdoor area, wherein the space (1) through at least one supply air duct (2) supply air supplied and from the Room (1) through at least one exhaust duct (3) exhaust air is discharged, wherein the air pressure in the space (1) by means of a first regulator (12), which is preferably suitable for controlling small fluctuations in the air pressure, is regulated so that an air pressure difference between the room (1) and the outside area is always less than zero, wherein in an in the room (1) entering fire an extinguishing agent in the room (1) is initiated.

Um einen Einsatz eines Löschmittels zur Bekämpfung eines Brandfalles in einem im Wesentlichen gasdichten Raum (1) zu ermöglichen, ohne dass ein ungefilterter Luftaustausch zwischen dem Raum (1) und dem Außenbereich nötig wird, wird das Verfahren erfindungsgemäß dadurch ergänzt, dass in einem in dem Raum (1) eintretenden Brandfall ein Löschmittel eingeleitet wird und dass während der Einleitung des Löschmittels der Luftdruck in dem Raum (1) mittels eines zweiten Reglers (13) geregelt wird.In order to enable the use of an extinguishing agent to combat a fire in a substantially gas-tight room (1), without an unfiltered air exchange between the room (1) and the outside area is necessary, the method is supplemented according to the invention that in a in the Room (1) entering fire an extinguishing agent is introduced and that during the introduction of the extinguishing agent, the air pressure in the room (1) by means of a second regulator (13) is controlled.

Die Erfindung betriff ferner eine Vorrichtung, mittels derer das erfindungsgemäße Verfahren besonders einfach durchführbar ist.

The invention further relates to a device by means of which the method according to the invention is particularly simple to carry out.
