Description
Die Erfindung betrifft eine Rauchschutzdruckanlage für ein Gebäude, welches zumindest einen im Brandfall mit Überdruck zu beaufschlagenden Fluchtraum aufweist, mit zumindest einem den Fluchtraum im Brandfall mit Zuluft beaufschlagenden Zuluftventilator und einer Regelklappenvorrichtung, welche zumindest eine Regelklappe aufweist, welche bei Überschreitung eines Grenzüberdrucks öffnet und bei Unterschreitung des Grenzüberdrucks schließt.The invention relates to a smoke protection pressure system for a building, which has at least one in case of fire to be acted upon by pressure escape space, with at least one the escape space in case of fire with supply air acting on Zuluftventilator and a control valve device which has at least one control valve which opens when exceeding a limit overpressure and at Below the limit overpressure closes.
Gebäude meint im Rahmen der Erfindung insbesondere Gebäude mit einer Vielzahl von Etagen, welche über ein oder mehrere Treppenräume miteinander verbunden sind. Diese Treppenräume bilden Fluchträume, welche im Brandfall von Rauch freizuhalten sind. Die Rauchschutzanlage ist daher als Rauchschutz-Differenzdruckanlage ausgebildet, wobei durch den eingestellten Überdruck im Bereich des Fluchtraumes eine Rauchfreihaltung im Brandfall gewährleistet ist. Aus Sicherheitsgründen darf der für die Rauchfreihaltung erforderliche Überdruck einen zulässigen Maximalwert (z. B. 50 Pa) nicht überschreiten. Aus diesem Grunde ist eine Regelklappenvorrichtung vorgesehen, welche im Rahmen der Erfindung bevorzugt mit federbelasteten Regelklappen ausgerüstet ist, sodass für eine selbsttätige Luftabfuhr überschüssiger Luft gesorgt wird. Eine solche Regelklappenvorrichtung spricht sehr schnell an, sodass sie auch schnell auf das Öffnen und Schließen von Türen reagieren kann.In the context of the invention, building means, in particular, buildings with a multiplicity of floors, which are connected to one another via one or more staircases. These staircases form refuge rooms, which are to be kept free of smoke in case of fire. The smoke protection system is therefore designed as a smoke protection differential pressure system, which is ensured by the set pressure in the area of the escape room smoke control in case of fire. For safety reasons, the overpressure required for keeping smoke free must not exceed a permissible maximum value (eg 50 Pa). For this reason, a control valve device is provided, which is preferably equipped with spring-loaded control valves in the context of the invention, so that an automatic air removal excess air is taken care of. Such a flap device responds very quickly, so that it can respond quickly to the opening and closing of doors.
Eine derartige Rauchschutzdruckanlage ist beispielsweise aus der
Fluchträume in Hochhäusern (z. B. Treppenräume, aber auch Lüftungs- und Aufzugschächte) unterliegen Witterungseinflüssen, sofern sie Öffnungen zur freien Atmosphäre aufweisen. Im isothermen Fall (Innentemperatur = Außentemperatur) bleiben die Druckverhältnisse im Fluchtraum unbeeinflusst. Bei Unterschieden zwischen Innentemperatur und Außentemperatur, z. B. bei hohen Außentemperaturen im Sommer oder bei niedrigen Außentemperaturen im Winter, führen insbesondere Konvektionseinflüsse zu verschiedenen Durchströmungseffekten. Dieses führt über die Höhe des Fluchtraumes zu unterschiedlichen Druckverhältnissen, sodass die Funktion der Rauchschutzdruckanlage evtl. nicht mehr gewährleistet werden kann, und zwar insbesondere dann, wenn der Überdruck lokal den vorgegebenen Grenzüberdruck überschreitet, sodass dann die zulässigen Türöffnungskräfte überschritten werden. Ähnliches gilt, wenn lokal unzulässiger Unterdruck entsteht, sodass Rauch in den Treppenraum eintreten kann.Crawl spaces in high-rise buildings (eg staircases, but also ventilation and elevator shafts) are subject to weather conditions, provided they have openings to the free atmosphere. In the isothermal case (inside temperature = outside temperature), the pressure conditions in the escape area remain unaffected. For differences between internal temperature and outside temperature, z. B. at high outdoor temperatures in summer or at low outdoor temperatures in winter, in particular convection influences lead to different flow effects. This leads over the height of the escape space to different pressure conditions, so that the function of the smoke protection pressure system may no longer be guaranteed, especially if the overpressure locally exceeds the predetermined limit pressure, so then the permissible door opening forces are exceeded. The same applies if locally inadmissible negative pressure arises, so that smoke can enter the stairwell.
Ausgehend von dieser Problematik wird in der
Der Erfindung liegt die Aufgabe zugrunde, eine Rauchschutzdruckanlage für ein Gebäude der eingangs beschriebenen Art zu schaffen, welche bei einfachem Aufbau auch bei unterschiedlichsten Witterungsverhältnissen und insbesondere Außentemperaturen eine einwandfreie Rauchfreihaltung gewährleistet, ohne dass die in der Praxis beobachteten Probleme mit unzulässig hohen Türöffnungskräften auftreten.The invention has for its object to provide a smoke protection printing system for a building of the type described above, which ensures a simple structure even with different weather conditions and in particular outdoor temperatures flawless smoke control without the problems observed in practice occur with inadmissibly high door opening forces.
Zur Lösung dieser Aufgabe lehrt die Erfindung bei einer gattungsgemäßen Rauchschutzanlage der eingangs beschriebenen Art, dass im Fluchtraum über dessen Höhe verteilt mehrere Zuluftauslässe angeordnet sind, welche als ungeregelte Zuluftauslässe unabhängig von Druckschwankungen im Treppenraum ansteuerbar sind. Vorzugsweise sind die Zuluftauslässe zur Erzeugung einer über die Fluchtraumhöhe variablen Zuluftverteilung in Abhängigkeit von der Außentemperatur einzeln oder in Gruppen variabel ansteuerbar. Die Zuluftauslässe können dazu mit einzeln oder in Gruppen ansteuerbaren Zuluftklappen ausgerüstet sein. Auf diese Weise besteht zunächst einmal die Möglichkeit, in Abhängigkeit von der Außentemperatur bzw. in Abhängigkeit zwischen der Differenz zwischen Außentemperatur und Innentemperatur gezielt Einfluss auf die Zuluftverteilung über die Höhe des Treppenraumes zu nehmen und die Zuluftverteilung "gewichtet" an die Verhältnisse anzupassen, indem je nach Witterungsverhältnissen nicht nur eine homogene, sondern insbesondere auch eine veränderbare, inhomogene Zuluftverteilung über die Höhe realisiert wird. Von besonderer Bedeutung ist dabei außerdem die Tatsache, dass die Zuluftzufuhr ungeregelt erfolgt, das heißt die Zuluftauslässe selbst arbeiten ungeregelt, das heißt die Zuluftauslässe sind zwar in Abhängigkeit von der Außentemperatur einzeln ansteuerbar, die Ansteuerung erfolgt jedoch unabhängig von Druckschwankungen im Fluchtraum, die z. B. auftreten, wenn Türen, Fenster oder dergleichen im Fluchtraum geöffnet werden. Die Regelung erfolgt ausschließlich über die im Fluchtraum ohnehin vorgesehene Regelklappenvorrichtung, welche auf sich öffnende und schließende Türen regelfähig ist. Den Luftauslässen kommt keinerlei Regelfunktion zu, sodass der empfindliche Regelkreis nicht gestört wird. Insbesondere wird der Einsatz mehrerer unterschiedlicher Regelkreise ausdrücklich vermieden, sodass eine nicht mehr zu kontrollierende Beeinflussung verschiedener Regelkreise unterbleibt. Dennoch kann variabel auf Außentemperaturschwankungen reagiert werden, indem für eine über die Höhe gewichtete Zuluft-Volumenstromverteilung gesorgt wird.To solve this problem, the invention teaches in a generic smoke protection system of the type described above that distributed over the height of the escape space several Zuluftauslässe are arranged, which are controlled as unregulated Zuluftauslässe regardless of pressure fluctuations in the stairwell. Preferably, the supply air outlets for generating a variable over the escape space height Zuluftverteilung depending on the outdoor temperature individually or in groups can be controlled variably. The supply air outlets can be equipped with individually or in groups controllable inlet flaps. In this way, it is initially possible, depending on the outside temperature or as a function of the difference between the outside temperature and inside temperature to influence the supply air distribution over the height of the staircase and to adjust the supply air distribution "weighted" to the conditions, by depending not only a homogeneous, but in particular a variable, inhomogeneous supply air distribution over the height is realized according to weather conditions. Of particular importance is also the fact that the supply air is unregulated, that is, the supply air outlets work themselves unregulated, that is, the supply air outlets are individually controllable depending on the outside temperature, but the control is independent of pressure fluctuations in the refuge, the z. B. occur when doors, windows or the like are opened in the refuge. The regulation takes place exclusively via the control flap device which is provided anyway in the escape area and which is regulable for opening and closing doors. The air outlets have no control function, so that the sensitive control loop is not disturbed. In particular, the use of several different control loops is expressly avoided, so that a no longer controllable influencing different control circuits is omitted. Nevertheless, it is possible to react variably to outside temperature fluctuations by providing a height-weighted supply air volume flow distribution.
Die Zuluftklappen sind bevorzugt als motorisch betätigbare Klappen, z. B. Jalousieklappen, ausgebildet. Diese lassen sich motorisch öffnen und schließen, wobei auch Zwischenstellungen möglich sind. Insbesondere können kontinuierlich bzw. stufenlos zu öffnende Klappen, z. B. Jalousieklappen verwendet werden, die jedoch - wie erläutert - stets ungeregelt betrieben werden. Der Ventilator ist dabei vorzugsweise über zumindest einen gemeinsamen Zuluftschacht mit den Zuluftauslässen verbunden. Dieser Zuluftschacht erstreckt sich vorzugsweise über die gesamte Höhe oder zumindest im Wesentlichen die gesamte Höhe des Fluchtraumes. Jedenfalls ist es zweckmäßig, wenn sich der Zuluftschacht über die Höhe des Fluchtraumes erstreckt, in der Türen zu z. B. angrenzenden Brandräumen vorgesehen sind. Stets ist es zweckmäßig, eine Vielzahl von Luftauslässen (mit z. B. Zuluftklappen) über die Höhe des Fluchtraumes zu verteilen. So kann es zweckmäßig sein, pro Geschoss des Fluchtraumes (z. B. Treppenraumes) jeweils zumindest einen Luftauslass vorzusehen. Denkbar sind auch Varianten, bei denen nicht jedem Geschoss, sondern nur einem Bruchteil der Geschosse, z. B. jedem zweiten Geschoss oder auch jedem dritten Geschoss ein Luftauslass zugeordnet ist.The inlet flaps are preferred as a motor-operated flaps, z. As shutter valves, trained. These can be opened and closed by a motor, whereby intermediate positions are also possible. In particular, continuously or continuously opening flaps, z. B. shutter valves are used, but - as explained - are always operated unregulated. The fan is preferably connected via at least one common supply air shaft with the Zuluftauslässen. This supply air duct preferably extends over the entire height or at least substantially the entire height of the escape space. In any case, it is expedient if the supply air duct extends over the height of the escape space, in the doors to z. B. adjacent fire areas are provided. It is always expedient to distribute a large number of air outlets (with, for example, supply air flaps) over the height of the escape space. Thus, it may be expedient to provide at least one air outlet per floor of the escape area (eg staircase). Also conceivable are variants in which not everyone Projectile, but only a fraction of the projectiles, z. B. every second floor or every third floor is associated with an air outlet.
Nach einem weiteren Vorschlag der Erfindung mit selbstständiger Bedeutung ist der Gesamtvolumenstrom der Zuluft in Abhängigkeit von der Außentemperatur einstellbar, z. B. über den Zuluftventilator. Im Rahmen der Erfindung wird auf Temperaturschwankungen (z. B. Sommer/Winter) zum einen mit der unterschiedlichen Gewichtung der Zuluft-Volumenstromverteilung über die Höhe reagiert. Zum anderen kann jedoch auch der Gesamtvolumenstrom der Zuluft an die Außentemperatur angepasst werden. So ist es vorteilhaft, bei niedrigen Außentemperaturen einen höheren Zuluft-Volumenstrom zu wählen als bei niedrigen Außentemperaturen. Dieses lässt sich beispielsweise dadurch realisieren, dass der Ventilator durch eine Steuereinrichtung mit variabler Drehzahl betrieben wird. Dazu kann der Zuluftventilator bzw. dessen Steuereinrichtung mit einem Frequenzumrichter ausgerüstet sein. Außerdem ist besonders bevorzugt ein Außentemperatursensor vorgesehen, welcher mit dem Ventilator bzw. dessen Steuereinrichtung verbunden ist, sodass die Ventilatordrehzahl und damit der Zuluft-Volumenstrom in Abhängigkeit von der Außentemperatur variabel gestaltet werden kann. Sofern die (exakte) Temperaturdifferenz berücksichtigt wird, kann zusätzlich ein Innentemperatursensor vorgesehen sein.According to another proposal of the invention with independent significance of the total volume of supply air is adjustable depending on the outside temperature, z. B. on the supply air fan. In the context of the invention, temperature fluctuations (eg summer / winter) are reacted, on the one hand, to the different weighting of the supply air volume flow distribution over the height. On the other hand, however, the total volume flow of the supply air can be adapted to the outside temperature. So it is advantageous to select a higher supply air volume flow at low outside temperatures than at low outside temperatures. This can be realized, for example, in that the fan is operated by a variable-speed control device. For this purpose, the supply air fan or its control device may be equipped with a frequency converter. In addition, an outside temperature sensor is particularly preferably provided, which is connected to the fan or its control device, so that the fan speed and thus the supply air volume flow can be made variable depending on the outside temperature. If the (exact) temperature difference is taken into account, an internal temperature sensor may additionally be provided.
Bei der im Rahmen der Erfindung eingesetzten Regelklappenvorrichtung kann auf herkömmliche Regelklappenvorrichtungen zurückgegriffen werden. Die Regelklappen können motorisch geregelt werden. Bevorzugt sind jedoch federbelastete, selbsttätig öffnende und schließende Regelklappen vorgesehen, wie sie beispielsweise auch in der
Auch bei den Zuluftklappen kann auf Klappen, z. B. Jalousieklappen, aus dem Stand der Technik zurückgegriffen werden, wobei diese Klappen - wie erläutert - ungeregelt sind. Insgesamt lässt sich die Erfindung daher kostengünstig realisieren. Dennoch ist eine einwandfreie Funktion gewährleistet.Even with the inlet flaps can on flaps, z. As shutter valves are used in the prior art, these flaps - as explained - are unregulated. Overall, the invention can therefore be realized inexpensively. Nevertheless, a perfect function is guaranteed.
Gegenstand der Erfindung ist auch ein Verfahren zur Rauchfreihaltung eines Fluchtraumes, insbesondere unter Einsatz der beschriebenen Rauchschutzdruckanlage, wobei der Fluchtraum im Brandfall mit einem Überdruck beaufschlagt wird, der einen vorgegebenen Grenzüberdruck nicht überschreitet. Dieses Verfahren ist erfindungsgemäß dadurch gekennzeichnet, dass die Zuluft über mehrere über die Höhe des Fluchtraumes verteilte, ungeregelte Luftauslässe, z. B. mit von der Außentemperatur abhängiger variabler Zuluftverteilung zugeführt wird. Kern des erfindungsgemäßen Verfahrens ist folglich insbesondere die ungeregelte Zuströmung, und zwar vorzugsweise mit über die Höhe gewichteter, das heißt variabel/veränderbar an die Gegebenheiten anpassbarer Zuluft-Volumenstromverteilung. Ergänzend kann der Gesamtvolumenstrom der Zuluft in Abhängigkeit von der Außentemperatur eingestellt werden.The invention also provides a method for keeping smoke in an escape space, in particular using the described smoke protection printing system, wherein the escape space is exposed to an overpressure in case of fire, which does not exceed a predetermined limit pressure. This method is inventively characterized in that the supply air over several distributed over the height of the escape space, unregulated air outlets, z. B. is supplied with dependent on the outside temperature variable supply air distribution. The core of the method according to the invention is consequently, in particular, the uncontrolled inflow, preferably with an intake air volume flow distribution which is weighted over the height, that is to say variably / variably adaptable to the circumstances. In addition, the total volume flow of the supply air can be set as a function of the outside temperature.

Die Zuluftauslässe 4 sind nun in Abhängigkeit von der Außentemperatur einzeln oder in Gruppen variabel ansteuerbar. Dazu können die Zuluftauslässe 4 beispielsweise mit nicht dargestellten Zuluftklappen ausgerüstet sein, welche motorisch betätigt und folglich motorisch geöffnet und geschlossen werden können, wobei die einzelnen Zuluftklappen unabhängig voneinander geöffnet und geschlossen werden können. Damit besteht die Möglichkeit, eine über die Fluchtraumhöhe H variable Zuluftverteilung und folglich eine über die Höhe gewichtete Zuluft-Volumenstromverteilung zu erzeugen. Dieses ergibt sich aus einer vergleichenden Betrachtung der
