Description

Die Erfindung bezieht sich auf ein Luftverteilungssystem einer Belüftungsanlage.The invention relates to an air distribution system of a ventilation system.

Bei Belüftungssystemen gemäß dem Stand der Technik ist die Strömungsrichtung zumeist unveränderlich festgelegt. So wird in der Regel verbrauchte Luft aus der Küche, dem Bade- und Schlafzimmer abgezogen und frische Luft Wohn- und Arbeitszimmern zugeführt.In ventilation systems according to the prior art, the flow direction is fixed mostly immutable. So usually used air is taken from the kitchen, the bathroom and bedroom and fresh air supplied to living and working rooms.

Aus DE 102013100056 B3 ist ein Belüftungssystem bekannt, bei dem die Richtung der Durchströmung geändert werden kann um jahreszeitlich bedingte Umgebungsbedingungen zu berücksichtigen. So wird im Sommer ein Luftstrom zunächst in Aufenthaltsräume geleitet und mit der verbrauchten Luft eine Computeranlage gekühlt. Im Winter heizen zunächst die Computer die frische Luft auf, ehe diese in die Aufenthaltsräume gelangt.Out DE 102013100056 B3 a ventilation system is known in which the direction of the flow can be changed to take into account seasonal environmental conditions. In the summer, for example, a stream of air is first channeled into recreation rooms and a computer system is cooled with the used air. In winter, the computers first heat up the fresh air before it reaches the common rooms.

Eine individuelle Durchströmung von Räumen ja nach Rahmenbedingungen ist aus dem Stand der Technik nicht bekannt.An individual flow of rooms according to general conditions is not known from the prior art.

Es ist daher Aufgabe der Erfindung, bei einem Belüftungssystem eine einfache Möglichkeit zu schaffen, Räume bedarfsgerecht zu belüften, so dass sie alternativ mit Zuluft versorgt oder Abluft aus ihnen abgezogen werden kann. Ein weiteres Ziel ist es, den Massenstromausgleich des Luftverteilungssystems zu optimieren.It is therefore an object of the invention to provide a simple way in a ventilation system to ventilate rooms as needed, so that they alternatively supplied with supply air or exhaust air can be withdrawn from them. Another goal is to optimize the mass flow balance of the air distribution system.

Diese Aufgabe wird gemäß den Merkmalen des Anspruchs 1 dadurch gelöst, dass ein Belüftungssystem eine Umschalteinrichtung mit einer Frischluftzufuhr und einer Abluftabführung aufweist. Diese münden in zwei getrennte Kammern, welche über Umschaltventile mit den Anschlussleitungen der zu belüftenden Räume verbunden sind. Die Umschaltventile ermöglichen eine Verbindung der jeweiligen Räume mit der Zu- oder Abluft.This object is achieved according to the features of claim 1, characterized in that a ventilation system has a switching device with a fresh air supply and an exhaust air discharge. These lead to two separate chambers, which are connected via changeover valves to the connecting lines of the spaces to be ventilated. The change-over valves allow the respective rooms to be connected to the supply or exhaust air.

Vorteilhafte Ausgestaltungen ergeben sich durch die Merkmale der abhängigen Ansprüche.Advantageous embodiments result from the features of the dependent claims.

Die Erfindung wird nun anhand der Figur erläutert.The invention will now be explained with reference to the figure.

Figur 1 zeigt schematisch eine Umschalteinrichtung 1 für ein Belüftungssystem mit einer Frischluftzufuhr 2 und einer Abluftabführung 3. Die Frischluftzufuhr 2 mündet in einer ersten Kammer 4, die Abluftabführung 3 in einer zweiten Kammer 5. Aus der ersten Kammer 4 münden ferner vier Anschlussleitungen 6.1, 6.2, 6.3. Jede Anschlussleitung 6.1, 6.2, 6.3, 6.4 ist mit einem Umschaltventil 7.1, 7.2, 7.3 verbunden. Die Umschaltventile 7.1, 7.2, 7.3 verbinden die Anschlussleitungen 6.1, 6.2, 6.3 jeweils entweder mit der ersten Kammer 4 oder mit der zweiten Kammer 5. Die Umschaltventile 7.1, 7.2, 7.3 können einzeln auch so eingestellt werden, dass die Anschlussleitungen 6.1, 6.2, 6.3 weder mit der ersten Kammer 4, noch mit der zweiten Kammer 5 verbunden sind, sondern vielmehr die Anschlussleitungen 6.1, 6.2, 6.3 absperren. FIG. 1 schematically shows a switching device 1 for a ventilation system with a fresh air supply 2 and an exhaust air discharge 3. The fresh air supply 2 opens in a first chamber 4, the exhaust air discharge 3 in a second chamber 5. From the first chamber 4 also open four connecting lines 6.1, 6.2, 6.3 , Each connecting line 6.1, 6.2, 6.3, 6.4 is connected to a switching valve 7.1, 7.2, 7.3. The switching valves 7.1, 7.2, 7.3 connect the connecting lines 6.1, 6.2, 6.3 each with either the first chamber 4 or with the second chamber 5. The switching valves 7.1, 7.2, 7.3 can also be individually adjusted so that the connecting lines 6.1, 6.2, 6.3 are connected to neither the first chamber 4, nor with the second chamber 5, but rather shut off the connecting lines 6.1, 6.2, 6.3.

Die Figuren 2 bis 4 zeigen eine besondere Ausführungsform der erfindungsgemäßen Umschalteinrichtung 1. Figur 2 zeigt hierbei die geschlossene Umschalteinrichtung 1, während Figur 3 diese geöffnet zeigt, so dass die Umschaltventile 7.1, 7.2, 7.3, 7.4 zu erkennen sind. Die erste Kammer 4 ist von der zweiten Kammer 5 durch eine Trennwand 11 getrennt, so dass keine Luft von der ersten Kammer 4 zur zweiten Kammer 5 strömen kann. Jedes Umschaltventil 7.1, 7.2, 7.3, 7.4 besteht aus einem ersten Hohlrohr 8, das in die erste Kammer 4 ragt und mit jeweils einer Anschlussleitung 6.1, 6.2, 6.3, 6.4 verbunden ist, einem geschlossenen Rohr 9, das in zweite Kammer 5 ragt und koaxial zu dem korrespondierenden ersten Hohlrohr 8 ausgerichtet ist, und einem zweiten Hohlrohr 10, das die Trennwand 8 durchdringt und koaxial zu dem korrespondierenden ersten Hohlrohr 8 ausgerichtet ist.The FIGS. 2 to 4 show a particular embodiment of the switching device 1 according to the invention. FIG. 2 shows here the closed switching device 1, while FIG. 3 this shows open, so that the switching valves 7.1, 7.2, 7.3, 7.4 are visible. The first chamber 4 is separated from the second chamber 5 by a partition 11 separated, so that no air from the first chamber 4 to the second chamber 5 can flow. Each switching valve 7.1, 7.2, 7.3, 7.4 consists of a first hollow tube 8, which projects into the first chamber 4 and is connected to a connecting line 6.1, 6.2, 6.3, 6.4, a closed tube 9, which projects into the second chamber 5 and is aligned coaxially with the corresponding first hollow tube 8, and a second hollow tube 10 which penetrates the partition 8 and is aligned coaxially with the corresponding first hollow tube 8.

Bei jedem Umschaltventile 7.1, 7.2, 7.3, 7.4 sind das zweiten Hohlrohr 10, das korrespondierende geschlossene Rohr 9 sowie korrespondierende erste Hohlrohr 8 derart aufeinander abgestimmt, dass das zweite Hohlrohr 10 das erste Hohlrohr 9 sowie das geschlossene Rohr 9 in der entsprechenden Schaltstellung abdichten kann. Hierzu muss im Wesentlichen der Innenquerschnitt des zweiten Hohlrohrs 10 auf der entsprechenden Seite jeweils dem Außenquerschnitt des ersten Hohlrohrs 9 sowie des geschlossenen Rohrs 9 entsprechen. Hierbei ist eine entsprechende Passung zu wählen, die bei der Verwendung einer Dichtung entsprechend anzupassen ist. Dementsprechend ist bei Verwendung einer Dichtung ein entsprechender Spalt zwischen dem zweiten Hohlrohr 10 sowie dem ersten Hohlrohr 9 und dem geschlossenen Rohr 9 notwendig. Die Querschnitte können, müssen hierbei nicht zwingend kreissymmetrisch und auch nicht auf beiden Seiten identisch sein.In each switching valves 7.1, 7.2, 7.3, 7.4, the second hollow tube 10, the corresponding closed tube 9 and corresponding first hollow tube 8 are coordinated such that the second hollow tube 10, the first hollow tube 9 and the closed tube 9 can seal in the corresponding switching position , For this purpose, the inner cross section of the second hollow tube 10 on the corresponding side must essentially correspond in each case to the outer cross section of the first hollow tube 9 and of the closed tube 9. Here, a corresponding fit is to be selected, which must be adapted accordingly when using a seal. Accordingly, when using a seal, a corresponding gap between the second hollow tube 10 and the first hollow tube 9 and the closed tube 9 is necessary. The cross sections can, but do not necessarily have to be circularly symmetrical and not identical on both sides.

Figur 4 zeigt die beiden ersten Umschaltventile 7.1, 7.2 in jeweils unterschiedlicher Schaltstellung. Das erste Umschaltventil 7.1 ist derart geschaltet, dass sein zweites Hohlrohr 10 die Verbindung der Anschlussleitung 6.1 über das erste Hohlrohr 8 mit der ersten Kammer 4 verschließt, die Verbindung zu der zweiten Kammer 5 jedoch herstellt. Somit kann über die Anschlussleitung 6.1 Luft abgesaugt werden. Das zweite Umschaltventil 7.2 ist derart geschaltet, dass die Anschlussleitung 6.2 über das erste Hohlrohr 8 mit der ersten Kammer 4 verbunden ist. Das zweite Hohlrohr 10 schließt mit dem geschlossenen Rohr 9 die Verbindung zu der zweiten Kammer 5. Somit kann über die Anschlussleitung 6.2 Luft zugeführt werden. Es ist auch möglich, das zweite Hohlrohr 10 derart zu stellen, dass die Anschlussleitungen 6.1, 6.2, 6.3, 6.4 weder Kontakt zu der ersten Kammer 4, noch der zweiten Kammer 5 hat, indem das zweite Hohlrohr 10 mittig positioniert wird. Hierzu ist es notwendig, dass das zweite Hohlrohr 10 eine axiale Erstreckung hat, die länger ist als der Abstand zwischen dem ersten Hohlrohr 8 und dem geschlossenen Rohr 9. In beiden Endpositionen des zweiten Hohlrohres 10 muss gewährleistet sein, dass das zweite Hohlrohr 10 eine Kammer 4, 5 bis zur Trennwand 11 abdichtet. FIG. 4 shows the first two switching valves 7.1, 7.2 each in different switching position. The first switching valve 7.1 is connected such that its second hollow tube 10 closes the connection of the connecting line 6.1 via the first hollow tube 8 with the first chamber 4, the connection to the second chamber 5, however, produces. Thus, air can be sucked off via the connection line 6.1. The second switching valve 7.2 is connected in such a way that the connection line 6.2 is connected to the first chamber 4 via the first hollow tube 8. The second hollow tube 10 closes with the closed tube 9, the connection to the second chamber 5. Thus, via the connecting line 6.2 air be supplied. It is also possible to set the second hollow tube 10 such that the connection lines 6.1, 6.2, 6.3, 6.4 neither contact the first chamber 4, nor the second chamber 5 by the second hollow tube 10 is positioned centrally. For this purpose, it is necessary that the second hollow tube 10 has an axial extent which is longer than the distance between the first hollow tube 8 and the closed tube 9. In both end positions of the second hollow tube 10, it must be ensured that the second hollow tube 10 is a chamber 4, 5 seals to the partition wall 11.

Sind die Umschaltventile 7.1, 7.2, 7.3, 7.4 kontinuierlich verstellbar, so lässt sich auch der Massenstrom kontinuierlich reduzieren ohne dabei die Gesamtzufuhr und / oder -abfuhr zu beeinflussen. Sind in den Anschlussleitungen 6.1, 6.2, 6.3, 6.4 Massenstromsensoren integriert, so lässt sich der Massenstrom individuell regeln.If the changeover valves 7.1, 7.2, 7.3, 7.4 are continuously adjustable, the mass flow can be continuously reduced without affecting the overall supply and / or discharge. If mass flow sensors are integrated in the connection lines 6.1, 6.2, 6.3, 6.4, the mass flow can be regulated individually.

Im vorleigenden Fall, auf den die Erfindung nicht begrenzt ist, sind die ersten Hohlrohre 8, die zweiten Hohlrohre 10 sowie die geschlossenen Rohre 9 jeweils zylindrisch.In the present case, to which the invention is not limited, the first hollow tubes 8, the second hollow tubes 10 and the closed tubes 9 are each cylindrical.

Der Antrieb der zweiten Hohlrohre 10 kann von außerhalb der Umschalteinrichtung 1 über abgedichtete Spindeln oder andere Antriebe erfolgen. Der Antrieb kann auch in der Umschalteinrichtung 1 direkt erfolgen.The drive of the second hollow tubes 10 can be done from outside the switching device 1 via sealed spindles or other drives. The drive can also be done directly in the switching device 1.

Figur 5 zeigt die Umschaltvorrichtung gemäß Figur 4 mit einem konkreten Antriebskonzept der umschaltenden Hohlrohre 10. In den geschlossenen Rohren 9 sind elektrische Antriebsmotoren 15 angeordnet. Über ein mit den Antriebsmotoren 15 verbundenes Gewinde 16 wird jeweils eine Spindel 17 angetrieben; diese Spindeln 17 sind über Verbindungen 18 mit den Hohlrohren 10 verbunden. Führungsschienen 19 verhindern ein Verdrehen. FIG. 5 shows the switching device according to FIG. 4 with a concrete drive concept of the switching hollow tubes 10. In the closed tubes 9 electric drive motors 15 are arranged. About a connected to the drive motors 15 thread 16 a spindle 17 is driven in each case; these spindles 17 are connected via connections 18 with the hollow tubes 10. Guide rails 19 prevent twisting.

Figur 6 zeigt ein Haus mit der erfindungsgemäßen Umschalteinrichtung 1 sowie mehreren Räumen 12, 13. Im Ausführungsbeispiel gemäß Figur 5 wird aus mit 12 bezeichneten Räumen Luft abgezogen und mit 13 bezeichneten Räumen Luft zugeführt. Verbindungen 14 zwischen den Räumen 12, 13 erlauben eine Luftströmung über Räume 12, 13 hinweg, so dass die den Räumen 13 zugeführte Luft über die Verbindungen 14 in die Räume 12 strömt und von dort wieder in die Umschalteinrichtung 1 geführt. FIG. 6 shows a house with the switching device 1 according to the invention and several rooms 12, 13. In the embodiment according to FIG. 5 is deducted from 12 spaces designated air and supplied with 13 designated spaces air. Connections 14 between the spaces 12, 13 allow an air flow over spaces 12, 13, so that the air supplied to the spaces 13 flows via the connections 14 into the spaces 12 and from there back into the switching device 1.

Bedarfsgerecht kann somit eine Luftverteilung gewährleistet werden. So kann zu bestimmten Zeiten eine Zufuhr zu bestimmten Räumen gewünscht sein, während zu anderen Zeiten oder bei anderen Rahmenbedingungen ein Abzug bei diesen Räumen gewünscht ist.As required, an air distribution can thus be ensured. Thus, at certain times a supply to certain rooms may be desired, while at other times or in other circumstances, a deduction in these rooms is desired.

So muss beim Kochen in Küchen, nachts in Schlafzimmern und beim Benutzen einer Toilette ein Luftabzug gewährleistet werden. Zu anderen Zeiten kann jedoch auch Frischluft diesen Räumen zugeführt werden und über die Verbindung der Räume kann dann diese Luft in andere Räume strömen. Einzelne Räume können auch bedarfsgerecht von der Zu- oder Abführung ausgenommen werden, wenn beispielsweise ein Raum temporär nicht bewohnt ist, was durch die Temperaturvorgabe eines Thermostaten erkannt werden kann. Ist in einem Raum ein Sensor zur Erkennung der Luftqualität angerordnet, so kann dieser Raum bedarfsgerecht bei guter Raumluft auch aus der Zu- oder Abführung ausgenommen werden beziehungsweise dessen Luftbedarf reduziert werden.So when cooking in kitchens, at night in bedrooms and when using a toilet, an air vent must be guaranteed. At other times, however, fresh air can be supplied to these rooms and the connection of the rooms then this air can flow into other rooms. Individual rooms can also be excluded as needed from the supply or discharge, for example, if a room is temporarily not inhabited, which can be detected by the temperature setting of a thermostat. If a sensor for detecting the air quality is ordered in a room, then this room can also be exempted from the supply or discharge with good room air or its air requirement can be reduced.

Ein Raum kann auch mit sowohl einer Luftzuführung, als auch - abführung verbunden sein. Dies ist beispielsweise bei Schlafzimmern sinnvoll.A room can also be connected to both an air supply and exhaust. This is useful, for example, in bedrooms.
