Abstract

Dezentrales Lüftungsgerät mit Wärmetauscher, dadurch gekennzeichnet das im Lüftungskanal unter anderem ein oder mehrere Reversierventilatoren sowie ein Wärmetauscher zwischen Einlass und Auslass integriert sind.Decentralized ventilation unit with heat exchanger, characterized in that in the ventilation duct, inter alia, one or more reversing fans and a heat exchanger between the inlet and outlet are integrated.

Description

Stand der TechnikState of the art

Dezentrale Lüftungssysteme mit und ohne Wärmerückgewinnung werden in die Aussenwand implementiert und sind Stand der Technik.Decentralized ventilation systems with and without heat recovery are implemented in the outer wall and are state of the art.

Dezentrale Lüftungssysteme mit bidirektional betriebenen Axialventilatoren besitzen oft eine flache Druckkennlinie. Diese Ventilatoren sind anfällig für höhere Winddrücke und können deshalb nicht in allen Regionen verbaut werden.Decentralized ventilation systems with bidirectionally operated axial fans often have a flat pressure characteristic. These fans are prone to higher wind pressures and therefore can not be installed in all regions.

Eine Steuerung mit integriertem Drucksensor im Lüftergehäuse oder direkt am Lüfter soll Abweichungen zum Sollzustand ermitteln. Durch die ermittelten Daten kann der Ventilator die Abweichung zum Sollzustand ausgleichen. Dies kann zum Beispiel mithilfe einer Drehzahlerhöhung geschehen.A controller with integrated pressure sensor in the fan housing or directly at the fan should determine deviations from the nominal state. The determined data allows the fan to compensate for the deviation from the nominal state. This can be done, for example, by using a speed increase.

Dezentrales Lüftungsgerät mit Wärmetauscher, dadurch gekennzeichnet das im Lüftungskanal unter anderem ein oder mehrere Reversierventilatoren sowie ein Wärmetauscher zwischen Einlass und Auslass integriert sind.Decentralized ventilation unit with heat exchanger, characterized in that in the ventilation duct, inter alia, one or more reversing fans and a heat exchanger between the inlet and outlet are integrated. Gerät nach Anspruch 1, dadurch gekennzeichnet das sich ein Drucksensor im Lüftungskanal befindet. Dieser kann direkt am Ventilator oder auch an jedem beliebigem Platz im Lüftungskanal integriert werden.Device after Claim 1 , characterized in that there is a pressure sensor in the ventilation duct. This can be integrated directly on the fan or at any place in the ventilation duct. Gerät nach Anspruch 1 und 2, dadurch gekennzeichnet das mithilfe einer Software die Daten des Drucksensors ausgewertet werden. Bei anliegendem Über- oder Unterdruck kann sich die Drehzahl des Ventilators verändern. Wenn die Ventilatorkenndaten bei Über- oder Unterdruck bekannt sind, dann kann die Software die Drehzahl wieder angleichen um den Sollzustand zu erreichen. Somit versucht die Steuerung der abweichenden Drehzahl entgegenzuwirken.Device after Claim 1 and 2 , characterized in that the data of the pressure sensor are evaluated by means of software. If there is an overpressure or underpressure, the fan speed may change. If the fan characteristics are known at over or under pressure, then the software can readjust the speed to reach the desired state. Thus, the controller tries to counteract the deviating speed. Dezentrales Lüftungsgerät ohne Wärmetauscher, dadurch gekennzeichnet das im Lüftungskanal unter anderem ein oder mehrere Reversierventilatoren sowie ein Wärmetauscher zwischen Einlass und Auslass integriert sind.Decentralized ventilation unit without heat exchanger, characterized in that one or more reversing fans and a heat exchanger between inlet and outlet are integrated in the ventilation duct, among other things. Gerät nach Anspruch 4, dadurch gekennzeichnet das sich ein Drucksensor im Lüftungskanal befindet. Dieser kann direkt am Ventilator oder auch an jedem beliebigem Platz im Lüftungskanal integriert werden.Device after Claim 4 , characterized in that there is a pressure sensor in the ventilation duct. This can be integrated directly on the fan or at any place in the ventilation duct. Gerät nach Anspruch 4 und 5, dadurch gekennzeichnet das mithilfe einer Software die Daten des Drucksensors ausgewertet werden. Bei anliegendem Über- oder Unterdruck kann sich die Drehzahl des Ventilators verändern. Wenn die Ventilatorkenndaten bei Über- oder Unterdruck bekannt sind, dann kann die Software die Drehzahl wieder angleichen um den Sollzustand zu erreichen. Somit versucht die Steuerung der abweichenden Drehzahl entgegenzuwirken.Device after Claim 4 and 5 , characterized in that the data of the pressure sensor are evaluated by means of software. If there is an overpressure or underpressure, the fan speed may change. If the fan characteristics are known at over or under pressure, then the software can readjust the speed to reach the desired state. Thus, the controller tries to counteract the deviating speed.
