Description

Die Erfindung bezieht sich auf eine Umschalteinrichtung für ein Belüftungssystem. 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.The invention relates to a switching device for a ventilation system. In the case of ventilation systems according to the prior art, the direction of flow is mostly fixed unchangeably. As a rule, stale air is extracted from the kitchen, bathroom and bedroom and fresh air is supplied to living rooms and work 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 seasonal environmental conditions into account. In summer, for example, an air flow is first directed into lounges and a computer system is cooled with the stale air. In winter, the computers first heat up the fresh air before it gets into the common rooms.

Die Patentanmeldung EP 048016 A2 offenbart eine Lüftungs- und Heizungsanlage zur energiesparenden Lüftung und Einhaltung einer gewünschten Temperatur, insbesondere für hohe Räume. Die Anlage verfügt über Einrichtungen zur Luftzu- und -abführung für den zu lüftenden und/oder zu heizenden Raum und über mindestens eine Luftheizeinheit zur Aufheizung der Zuluft. Die Lüftungsöffnungen arbeiten im Sommer als in die Aufenthaltszone gerichtete Zuluftöffnungen und im Winter als Absaugöffnungen und umgekehrt.The patent application EP 048016 A2 discloses a ventilation and heating system for energy-saving ventilation and maintaining a desired temperature, especially for high rooms. The system has facilities for supplying and removing air for the room to be ventilated and / or heated and at least one air heating unit for heating the supply air. The ventilation openings work in summer as supply air openings directed into the occupied zone and in winter as extraction openings and vice versa.

Die Patentanmeldung JP H11173623 A lehrt, einen Luftstrom durch mehrere Räume abhängig davon zu steuern, in welchem Raum sich eine Person aufhält, um eine Kondensation zu vermeiden.The patent application JP H11173623 A teaches to control air flow through multiple rooms depending on which room a person is in to avoid condensation.

Es ist 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.The object of the invention is to create a simple possibility in a ventilation system to ventilate rooms as required, so that they can alternatively be supplied with supply air or exhaust air can be extracted from them. Another goal is to optimize the mass flow equalization of the air distribution system.

Diese Aufgabe wird durch eine Umschalteinrichtung mit den Merkmalen von Anspruch 1 gelöst. Vorgesehen ist dabei eine Umschalteinrichtung für ein Belüftungssystem welches eine Frischluftzufuhr und eineThis object is achieved by a switching device with the features of claim 1. A switchover device for a ventilation system which has a fresh air supply and a

Abluftabführung aufweist. Diese münden in zwei getrennte Kammern, welche über Umschaltventile in Form von Hohlrohren mit den Anschlussleitungen der zu belüftenden Räume verbunden sind. Die Umschaltventile ermöglichen eine Verbindung der jeweiligen Räume mit der Zu- oder Abluft.Has exhaust air discharge. These open into two separate chambers, which are connected to the connection lines of the rooms to be ventilated via switching valves in the form of hollow tubes. The switching valves enable the respective rooms to be connected to the supply or exhaust air.

Vorteilhafte Ausgestaltungen ergeben sich durch die Merkmale der abhängigen Ansprüche. Die Erfindung wird nun anhand der Figur erläutert.Advantageous refinements result from the features of the dependent claims. 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. Figure 1 shows schematically 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 into a first chamber 4, the exhaust air discharge 3 into a second chamber 5. Four connection lines 6.1, 6.2, 6.3 also open out of the first chamber 4 . Each connection 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 either to the first chamber 4 or to the second chamber 5. The switching valves 7.1, 7.2, 7.3 can also be set individually so that the connecting lines 6.1, 6.2, 6.3 neither with the first chamber 4, are still connected to 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 Figures 2 to 4 show a particular embodiment of the switching device 1 according to the invention. Figure 2 shows the closed switching device 1, while Figure 3 this shows open, so that the switching valves 7.1, 7.2, 7.3, 7.4 can be seen. The first chamber 4 is separated from the second chamber 5 by a partition 11, so that no air can flow from the first chamber 4 to the second chamber 5. Each switching valve 7.1, 7.2, 7.3, 7.4 consists of a first hollow tube 8 which protrudes into the first chamber 4 and is connected to a respective connection line 6.1, 6.2, 6.3, 6.4, a closed tube 9 which protrudes into the second chamber 5 and is oriented coaxially to the corresponding first hollow tube 8, and a second hollow tube 10 which penetrates the partition 8 and is oriented coaxially to 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. 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.In each switching valve 7.1, 7.2, 7.3, 7.4, the second hollow tube 10, the corresponding closed tube 9 and the corresponding first hollow tube 8 are coordinated with one another in such a way that the second hollow tube 10 can seal the first hollow tube 9 and the closed tube 9 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 to the outer cross section of the first hollow tube 9 and of the closed tube 9. An appropriate fit must be selected, which must be adapted accordingly when a seal is used. Accordingly, when a seal is used, a corresponding gap is necessary between the second hollow tube 10 and the first hollow tube 9 and the closed tube 9. The cross-sections can, in this case, do not necessarily have to be circularly symmetrical and also not identical on both sides. Figure 4 shows the first two switching valves 7.1, 7.2 in each different switching position. The first switchover valve 7.1 is switched in such a way that its second hollow tube 10 closes the connection between the connection line 6.1 via the first hollow tube 8 and the first chamber 4, but establishes the connection to the second chamber 5. This means that air can be extracted via the connection line 6.1. The second switchover valve 7.2 is switched 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 the connection to the second chamber 5 with the closed tube 9. Thus, air can be supplied via the connecting line 6.2. It is also possible to position the second hollow tube 10 in such a way that the connection lines 6.1, 6.2, 6.3, 6.4 have neither contact with the first chamber 4 nor the second chamber 5 by positioning the second hollow tube 10 in the middle. For this, it is necessary that the second hollow tube 10 has an axial extension that 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 up 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 also be continuously reduced without influencing 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 vorliegenden 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 second hollow tubes 10 can be driven from outside the switchover device 1 via sealed spindles or other drives. The drive can also take place 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. Figure 5 shows the switching device according to Figure 4 with a specific drive concept of the switching hollow tubes 10. Electric drive motors 15 are arranged in the closed tubes 9. A spindle 17 is driven via a thread 16 connected to the drive motors 15; these spindles 17 are connected to the hollow tubes 10 via connections 18. 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. Figure 6 shows a house with the switching device 1 according to the invention and several rooms 12, 13. In the embodiment according to Figure 5 air is drawn off from spaces designated by 12 and air is supplied to spaces designated by 13. Connections 14 between the rooms 12, 13 allow air to flow over rooms 12, 13, so that the air supplied to the rooms 13 flows via the connections 14 into the rooms 12 and from there again 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.Air distribution can thus be guaranteed as required. For example, at certain times a supply to certain rooms may be desired, while at other times or under other framework conditions, a discharge from 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.For example, ventilation must be ensured when cooking in kitchens, at night in bedrooms and when using a toilet. At other times, however, fresh air can also be supplied to these rooms and this air can then flow into other rooms via the connection between the rooms. Individual rooms can also be excluded from the supply or discharge as required, for example if a room is temporarily unoccupied, which can be recognized by the temperature setting of a thermostat. If a sensor for detecting the air quality is arranged in a room, this room can also be excluded from the inlet or outlet or its air requirement can be reduced if the room air is good.

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 inlet and an outlet. This is useful for bedrooms, for example.
