Abstract

The air conditioning installation has toxi gas detectors mounted separately and fed by inlet nozzles. A pneumatic switch operates a warning signal if the inlet nozzles should be destroyed by an explosion. The detectors (17, 1819) for the three different types of toxic gases which shut off the fan (8) and operate the quick-acting shutter (13) through the control unit (15) are remote controlled. They receive the air samples from inlet nozzles (5') in the intake channel (2) through a pump (20).

Description

Die Erfindung betrifft eine Vorrichtung nach Patent (P 27 43 107.8),The invention relates to a device according to patent (P 27 43 107.8),

in der Gasanzeigesonden in dem Frischluft-führenden Kanal mit Abstand von dem Ansauggitter angeordnet sind.in the gas indicator probes in the duct leading to the fresh air at a distance of are arranged on the intake grille.

Statt die Gasanzeigesonden selbst in dem Kanal anzuordnen und von diesen das Schaltgerät betätigen zu lassen, kann man auch nur die Ansaugstutzen der Anzeigesonden über den Querschnitt des Kanals verteilt in einer größeren Anzahl anordnen, die einzeln oder über ein Sammelrohr mit mehreren hintereinander geschalteten Analysengeräten der Gasanzeigesonden verbunden sind.Instead of arranging the gas indicator probes themselves in the channel and from them to operate the switchgear, you can only distribute the suction nozzle of the indicator probes over the cross-section of the channel in a larger one Arrange number, which are connected individually or via a collecting pipe with several analyzers connected in series with the gas indicator probes are.

Mit dieser Anordnung wird der gesamte Querschnitt des Kanals besser erfaßt, weil die schädlichen Gase unterschiedlicher Zusammensetzung in Höhen beliebiger Verteilung über den Kanalquerschnitt angesaugt und somit auf alle Fälle erfaßt werden, was bei abgestimmten Sonden nicht unbedingt gewährleistet ist.With this arrangement, the entire cross-section of the canal is better captured, because the harmful gases of different composition are sucked in at heights of any distribution over the channel cross-section and thus be recorded in any case, which is not necessarily guaranteed with coordinated probes.

Im Ausbau der in dieser Anmeldung und in der Hauptanmeldung enthaltenen Erfindung wird eine Sicherheitsvorrichtung für den Fall eingebaut, daß vor der Einführung von Giftgas die Gasanzeigesonden oder die Ansaugstutzen z.B. durch Sprengkörper zerstört werden, sodaß die Giftgase in die Belüftungsanlagen eindringen können, weil die Schnellschlußklappe nicht be- tätigt wird.In the expansion of the information contained in this application and in the main application Invention, a safety device is installed in the event that the gas indicator probes or the suction nozzle before the introduction of poisonous gas e.g. be destroyed by explosive devices so that the poison gases can penetrate the ventilation system because the quick-closing flap does not is made.

Die Lösungsmittel sind in den Ansprüchen 1 bis 4 näher gekennzeichnet.The solvents are characterized in more detail in claims 1 to 4.

In der Zeichnung ist in Fig. 1 schematisch die gleiche Klimaanlage wie nach der Figur der Hauptanmeldung mit Ansaugstutzen, Sicherheitsvorrich-In the drawing, the same air conditioning system is shown schematically in FIG. 1 according to the figure of the main application with intake manifold, safety device

Fig. 2 zeigt die Anlage nach der Figur der Hauptanmeldung mit einer Sicherheitsvorrichtung versehen.Fig. 2 shows the system according to the figure of the main application provided with a safety device.

In der Außenwand 1 eines Gebäudes ist als Einlaß für Frischluft in den Luftkanal 2 das Ansauggitter 3 angeordnet. Vor der Klimazentrale 4 sind im Kanal 2 über dessen Querschnitt verteilt mehrere Ansaugstutzen 5* eingebaut, die über das Sammelrohr 16 mit den auf verschiedene Gase abgestimmten Analysengeräten 17, 18, 19 verbunden sind. In das Sammelrohr 16 ist eine Pumpe 20 und ein pneumatischer Schalter 21 eingebaut. Die Analysengeräte sind mit der Schaltvorrichtung 15 leitend ver bunden und diese mit der Schnellschlußklappe 13 und dem Ventilator 8. Hinter dem letzten Analysengerät tritt die durch die Pumpe 20 angesaugte Luft über das Abluftrohr 16a ins Freie.In the outer wall 1 of a building is as an inlet for fresh air in the Air duct 2, the intake grille 3 arranged. In front of the air conditioning center 4, several suction nozzles 5 * are distributed over its cross section in duct 2 installed, which are connected via the manifold 16 to the analyzers 17, 18, 19, which are matched to various gases. A pump 20 and a pneumatic switch 21 are built into the collecting pipe 16. The analyzers are conductive ver with the switching device 15 bound and this with the quick-action flap 13 and the fan 8. Behind the last analyzer, the one sucked in by the pump 20 occurs Air through the exhaust pipe 16a to the outside.

Giftgase, die in den Kanal 2 gelangen, werden von der Pumpe 20 durch die Ansaugstutzen 5' angesaugt und über das Sammelrohr 16 den Analysen»· geräten zugeleitet. Falls dort ein Giftgas ermittelt wird, wird die Schaltvorrichtung 15 betätigt, die dann das Schließen der Schnellschlußklappe und das Stillsetzen des Ventilators 8 veranlaßt.Poison gases that get into the channel 2 are passed by the pump 20 the suction nozzle 5 'is sucked in and the analyzes »· devices. If a poison gas is detected there, the switching device 15 is actuated, which then closes the quick-action flap and causes the fan 8 to stop.

Sollten vor der Einführung von Gas in den Kanal 2 durch einen Sprengkörper die Ansaugstutzen 5' vernichtet werden, so entsteht im Sammel rohr 16 ein Unterdruck, der den pneumatischen Stromschalter 21 betätigt und damit eine Alarmanlage, z.B. im Gebäude verteilte Sirenen 22, in Gang setzt.If, before the introduction of gas into the channel 2, the suction nozzles 5 'are destroyed by an explosive device, this arises in the collection pipe 16 a negative pressure, which actuates the pneumatic power switch 21 and thus an alarm system, e.g. sirens 22 distributed in the building, in Sets gear.

In Figur 2 ist in die Stromleitung zwischen den Anzeigesonden 5 und der Schaltvorrichtung 15 ein Schalter 23 eingeschaltet, der bei Unterbrechung des Stromkreises durch Vernichtung der Anzeigesonden selbsttätig eine Alarmvorrichtung, z.B. Sirenen 22 oder Hupen, auslöst.In Figure 2 is in the power line between the display probes 5 and the Switching device 15, a switch 23 is switched on, the automatically a Alarm device, e.g. sirens 22 or horns, triggers.
