Abstract (en)

The liquefied gas pipes (5,24) from the container (1) to the zonal valve (9) are enclosed in thermal insulation to maintain CO2 in a liquefied condition. Any CO2 gas which forms in this pipe is fed back to the container through a valve (7)

Abstract (de)

In einer Feuerlöschanlage wird tiefkalte Kohlensäure als Löschmittel benutzt, in der CO2 in flüssiger Phase in einem isolierten Behälter (1) gelagert ist. Der Behälter wird mittels eines Kühlaggregates (3) auf tiefer Temperatur gehalten. Aus dem Behälter (1) führt eine Verteilerleitung (5) zu einer Löschleitung (8), die mit Löschdüsen (10) versehen ist. Das aus der Flüssigphase des Behälters (1) abgezogene Löschmittel ist innerhalb der Verteilerleitung (5) vom Behälter (1) zu einem Bereichsventil (9) gegen Kälteabstrahlung geschützt, wodurch das Löschmittel in der Verteilerleitung flüssig gehalten wird. Das sich in der Verteilerleitung (5) bildende, nach oben steigende CO2-Gas wird dort abgezogen und in die Gasphase des Behälters (1) zurückgeführt. Auf diese Weise wird sichergestellt, daß im Brandfall an den Löschdüsen (10) sogleich flüssiges Löschmittel verfügbar ist, ohne daß erst gasförmiges Löschmittel ausgeblasen werden müßte. <IMAGE>
