Abstract
Durch Löschgasdüsen wird eine hohe Turbulenz im Flutungsraum erzeugt. Die Turbulenz im Flutungsraum sorgt für eine homogene Konzentration im Flutungsraum, wodurch eine hohe Löschgaskonzentration den Flutungsraum über die Druckentlastung verlässt. Je mehr Löschgas den Flutungsraum verlässt, desto mehr Löschgas wird zum Erreichen der Auslegungskonzentration benötigt. Dies wiederum steigert die Flutungszeit. Mit steigender Flutungszeit steigt die Brandausbreitung und somit der Sachschaden, der mit finanziellem Schaden verbunden ist. Die turbulenzarme Löschgaseinbringung, beispielsweise über die Eindüsung von Löschgas in den Lüftungskanal (a) des Flutungsraum, sorgt für eine Entspannung des Löschgasstrahles bevor er in den Flutungsraum gelangt. Das Löschgas (Dichte schwerer als Luft) schichtet sich im Flutungsraum von unten nach oben. Damit das Gas nicht in den Lüftungskanal zurückströmt, muss dieser beispielsweise durch eine Gasdichteklappe verschlossen werden (b). Die Abfuhr des Löschgases über die Druckentlastung wird reduziert und die Zeit bis zum Erreichen der Löschgaskonzentration (Flutungszeit) wird verringert. Die turbulenzarme Löschgaseinbringung eignet sich für alle Anwendungsgebiete von Inertgas-Löschanlagen.Extinguishing gas nozzles produce high turbulence in the flooding area. The turbulence in the flooding chamber ensures a homogeneous concentration in the flooding chamber, whereby a high extinguishing gas concentration leaves the flooding chamber via the pressure relief. The more extinguishing gas leaves the flooding space, the more extinguishing gas is needed to reach the design concentration. This in turn increases the flood time. As flooding time increases, the spread of fire increases and thus the property damage, which is associated with financial damage. The low-turbulence quenching gas introduction, for example via the injection of extinguishing gas in the ventilation duct (a) of the flooding chamber, ensures a relaxation of the extinguishing gas jet before it enters the flooding chamber. The quenching gas (density heavier than air) stratified in the flooding space from bottom to top. So that the gas does not flow back into the ventilation duct, it must be closed, for example, by a gas density flap (b). The removal of the quenching gas via the pressure relief is reduced and the time until the extinguishing gas concentration (flooding time) is reached is reduced. The low-turbulence quenching gas is suitable for all applications of inert gas extinguishing systems.
Description
Die Planung und der Einbau von „Feuerlöschanlagen mit nicht verflüssigen Inertgasen” wird durch die
Die Richtlinie als Stand der Technik sieht für die Löschgaseinbringung konventionelle Löschgasdüsen vor. Durch Löschgasdüsen wird eine hohe Turbulenz im Flutungsraum erzeugt. Ursache hierfür sind die hohen Geschwindigkeiten der kritischen Ausströmungen des Gases an der Löschgasdüse.The state of the art guideline provides for the extinguishing gas introduction conventional extinguishing gas nozzles. Extinguishing gas nozzles produce high turbulence in the flooding area. This is due to the high speeds of the critical outgassing of the gas at the extinguishing gas nozzle.
Die Turbulenz im Flutungsraum sorgt für eine homogene Konzentration im Flutungsraum, wodurch eine hohe Löschgaskonzentration den Flutungsraum über die Druckentlastung verlässt. Je mehr Löschgas den Flutungsraum verlässt, desto mehr Löschgas wird zum Erreichen der Auslegungskonzentration benötigt. Dies wiederum steigert die Flutungszeit. Mit steigender Flutungszeit steigt die Brandausbreitung und somit der Sachschaden, der mit finanziellem Schaden verbunden ist.The turbulence in the flooding chamber ensures a homogeneous concentration in the flooding chamber, whereby a high extinguishing gas concentration leaves the flooding chamber via the pressure relief. The more extinguishing gas leaves the flooding space, the more extinguishing gas is needed to reach the design concentration. This in turn increases the flood time. As flooding time increases, the spread of fire increases and thus the property damage, which is associated with financial damage.
Dieses Problem wird durch die turbulenzarme Löschgaseinbringung gelöst. Das Löschgas (Dichte schwerer als Luft) schichtet sich im Flutungsraum von unten nach oben. Die mit der Erfindung erzielten Vorteile liegen darin, dass die Abfuhr des Löschgases über die Druckentlastung reduziert wird. Dadurch wird die Zeit bis zum Erreichen der Löschgaskonzentration (Flutungszeit) verringert und somit die Brandausbreitung und die damit verbundenen Sachschäden reduziert.This problem is solved by the low-turbulence quenching gas introduction. The quenching gas (density heavier than air) stratified in the flooding space from bottom to top. The advantages achieved by the invention are that the discharge of the quenching gas is reduced via the pressure relief. This reduces the time required to reach the quenching gas concentration (flooding time) and thus reduces the spread of fire and the associated damage to property.
