Description

Die Erfindung bezieht sich auf eine Haus- oder Wohnungslüftung in Verbindung mit einem brennstoffbeheizten Heizgerät mit Verbrennungsluftgebläse.The invention relates to a home or apartment ventilation in conjunction with a fuel-fired heater with combustion air blower.

Haus- oder Wohnungslüftungen in Verbindung mit einem atmosphärischen Heizgerät mit Strömungssicherung basieren auf dem technischen Effekt, dass ein atmosphärischer Gasbrenner Verbrennungsluft aus dem Aufstellraum ansaugt, diese Luft mit Brenngas vermischt wird, in einem Brenner verbrannt wird und letztendlich die heißen Abgase durch den thermischen Auftrieb zunächst durch eine Strömungssicherung strömen und dann über einen Kamin in die Umgebung abgegeben werden. Die Strömungssicherung reißt zugleich Frischluft aus dem Aufstellraum mit. Um die abgeführte Luft in dem Aufstellraum auszugleichen, strömt aus der Umgebung, insbesondere durch eine Öffnung in der Hausfassade, Frischluft in den Aufstellraum nach.Domestic or home ventilation in conjunction with a vented atmospheric heater is based on the technical effect that an atmospheric gas burner draws combustion air from the boiler room, mixes this with fuel gas, burns it in a burner, and ultimately the hot exhaust gases through thermal lift through a flow fuse and then discharged through a fireplace in the area. At the same time, the flow safety device tears fresh air out of the installation room. To compensate for the discharged air in the installation room, fresh air flows into the installation room from the environment, in particular through an opening in the house facade.

Moderne brennstoffbeheizte Heizgeräte, insbesondere Brennwertgeräte, verfügen über ein Verbrennungsluftgebläse, welches die Verbrennungsluft ansaugt und dafür sorgt, dass die Abgase mit Überdruck in die Umgebung abgeführt werden. Ist die Abgasleitung undicht, so können giftige Abgase entweichen. Daher verfügen brennstoffbeheizte Heizgeräte mit Verbrennungsluftgebläse oft über eine koaxiale Abgasleitung, bei der im Inneren eine Abgasleitung verläuft. Konzentrisch um diese Abgasleitung ist eine Frischluftleitung angeordnet, so dass austretendes Abgas aus der Abgasleitung in die Frischluftleitung eintritt und vom Verbrennungsluftgebläse in den Brenner angesaugt wird. Hierdurch wird vermieden, dass Abgase in den Aufstellraum gelangen können und Menschen gefährdet werden.Modern fuel-fired heaters, especially condensing boilers, have a combustion air blower, which sucks in the combustion air and ensures that the exhaust gases are discharged with excess pressure into the environment. If the exhaust pipe leaking, so toxic fumes can escape. Therefore, fuel-fired heaters with combustion air blower often have a coaxial exhaust pipe, which runs in the interior of an exhaust pipe. Concentric around this exhaust pipe is a fresh air line arranged, so that exiting exhaust gas from the exhaust pipe enters the fresh air line and is sucked by the combustion air blower in the burner. This avoids that exhaust gases can get into the room and people are endangered.

Wird ein atmosphärisches Heizgerät durch ein brennstoffbeheiztes Heizgerät mit Verbrennungsluftgebläse ersetzt, so wird zumeist die Abgasleitung durch den bestehenden Kamin geführt. Der verbleibende Ringspalt zwischen der Abgasleitung und der Kaminwand kann dann weiterhin für die Abführung von Luft aus den Wohnräumen genutzt werden. Es ist darauf zu achten, dass bei allen Betriebszuständen vermieden wird, dass austretendes Abgas in die Wohnräume gelangen kann.If an atmospheric heater replaced by a fuel-fired heater with combustion air blower, so the exhaust pipe is usually passed through the existing fireplace. The remaining annular gap between the exhaust pipe and the chimney wall can then continue to be used for the discharge of air from the living spaces. It must be ensured that it is avoided in all operating conditions that escaping exhaust gas can enter the living spaces.

Aus DE 29814722 U1 ist ein Gebäude mit mehreren Heizgeräten und einem Heizungsschacht bekannt. Aus dem Inneren des Hauses kann über einen Abgasventilator Abluft in einen Kaminschacht strömen. Aus demselben Kaminschacht können die Heizungsgeräte ihre Verbrennungsluft ziehen. DE 29814722 U1 offenbart eine Haus- oder Wohnungslüftung gemäß dem Oberbegriff von Anspruch 1. Aufgabe der vorliegenden Erfindung ist es, ein Haus- oder Wohnungsbelüftungssystem in Verbindung mit einem brennstoffbeheizten Heizgerät mit Verbrennungsluftgebläse zu schaffen, bei dem bei allen Betriebszuständen, insbesondere auch bei bestimmten Störungen, ein Abgasaustritt in Wohnräume sicher vermieden wird.Out DE 29814722 U1 is a building with several heaters and a heating shaft known. From the inside of the house exhaust air can flow into a chimney shaft via an exhaust fan. From the same chimney shaft, the heating devices can draw their combustion air. DE 29814722 U1 discloses a house or apartment ventilation according to the preamble of claim 1. The object of the present invention is to provide a home or apartment ventilation system in conjunction with a fuel-fired heater with combustion air blower in which in all operating conditions, especially in certain disorders, an exhaust gas outlet safely avoided in living spaces.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des unabhängigen Patentanspruchs gelöst. Gemäß den Merkmalen des abhängigen Anspruchs 2 handelt es sich bei dem Heizgerät um ein Brennwertgerät, bei welchem die Abgase unter den Taupunkt abgekühlt werden.According to the invention this object is solved by the features of the independent claim. According to the features of dependent claim 2, the heater is a condensing boiler in which the exhaust gases are cooled below the dew point.

Die Erfindung wird anhand der Figur detailliert erläutert.The invention will be explained in detail with reference to FIG.

Die Figur zeigt ein Haus 7 mit einem brennstoffbeheizten Heizgerät 1, welches über ein Verbrennungsluftgebläse 14 und eine Gaszufuhr 15 verfügt. Die Abgasleitung 2 des Heizgerätes 1 führt in und durch einen Kaminschacht 6 in die Umgebung 12 über eine Mündung 9. Zwischen dem Kaminschacht 6 und der Abgasleitung 2 befindet sich somit eine Ringleitung 11. Ein Abluftventilator 5 ist in einer Öffnung des Kaminschachts 6 angeordnet. Das Abgasrohr 2 ist zwischen dem Heizgerät 1 und dem Kaminschacht 6 von einer koaxialen Luftzufuhrleitung 3 umgeben. Die koaxiale Luftzufuhrleitung 3 endet in einem Gehäuse 17 mit Lüftungsgitter 4, wodurch eine Verbindung mit dem Inneren des Hauses 7 geschaffen wird. Das Gehäuse 17 ist über dem Abluftventilator 5 angeordnet, so dass auch die Ringleitung 11 im Kaminschacht 6 über den Abluftventilator 5 und das Lüftungsgitter 4 mit dem Inneren des Hauses 7 verbunden ist. Das Haus 7 verfügt ferner über eine Hausfassade 13, in der ein Lüftungseintritt 12 angeordnet ist. An der Mündung 9 des Abgasrohres 2 ist eine Regenhaube 10 angeordnet, welche die Öffnung 8 des Kaminschachts 6 überdeckt.The figure shows a house 7 with a fuel-fired heater 1, which has a combustion air blower 14 and a gas supply 15. The exhaust pipe 2 of the heater 1 leads into and through a chimney shaft 6 in the environment 12 via an orifice 9. Between the chimney 6 and the exhaust pipe 2 is thus a loop 11. An exhaust fan 5 is disposed in an opening of the chimney 6. The exhaust pipe 2 is surrounded by a coaxial air supply line 3 between the heater 1 and the chimney shaft 6. The coaxial air supply line 3 ends in a housing 17 with ventilation grille 4, whereby a connection with the interior of the house 7 is provided. The housing 17 is arranged above the exhaust fan 5, so that the ring pipe 11 is connected in the chimney 6 via the exhaust fan 5 and the ventilation grille 4 with the interior of the house 7. The house 7 also has a house facade 13, in which a ventilation inlet 12 is arranged. At the mouth 9 of the exhaust pipe 2, a rain cover 10 is arranged, which covers the opening 8 of the flue shaft 6.

Im reinen Lüftungsbetrieb fördert der Abluftventilator 5 Luft aus dem Inneren des Hauses 7 über das Lüftungsgitter 4 in die Ringleitung 11 des Kaminschachts 6. Die Luft wird über die Ringleitung 11 in die Umgebung 16 abgeführt. Hierdurch entsteht ein Unterdruck im Haus 7, wodurch aus der Umgebung 16 Frischluft durch den Lüftungseintritt 12 in der Hausfassade 13 in das Haus 7 eintritt. Wird das Heizgerät 1 in Betrieb genommen, so saugt das Verbrennungsluftgebläse 14 des Heizgeräts 1 Verbrennungsluft über die Luftzufuhrleitung 3 und das Lüftungsgitter 4 aus dem Inneren des Hauses 7 an. Auch hierdurch entsteht im Inneren des Hauses 7 ein Unterdruck, so dass wiederum Frischluft aus der Umgebung 16 durch den Lüftungseintritt 12 in der Hausfassade 13 in das Haus 7 geleitet wird. Die Abgase des Heizgerätes 1 werden über die Abgasleitung 2 in die Umgebung 16 abgeführt.In pure ventilation operation of the exhaust fan 5 promotes air from the interior of the house 7 via the ventilation grille 4 in the loop 11 of the chimney 6. The air is discharged through the loop 11 into the environment 16. This creates a negative pressure in the house 7, whereby 16 fresh air from the environment through the ventilation inlet 12 in the house facade 13 enters the house 7. When the heater 1 is put into operation, the combustion air blower 14 of the heater 1 sucks combustion air via the air supply pipe 3 and the ventilation grille 4 from inside the house 7. This also creates a negative pressure in the interior of the house 7, so that again fresh air from the environment 16 is passed through the ventilation inlet 12 in the house facade 13 in the house 7. The exhaust gases of the heater 1 are discharged via the exhaust pipe 2 into the environment 16.

Verfügt die Abgasleitung 2 im Bereich der Luftzufuhrleitung 3 über eine Undichtigkeit, so werden die Abgase mit der Verbrennungsluft von dem Verbrennungsluftgebläse 14 angesaugt und können somit nicht in den Aufstellraum gelangen.If the exhaust pipe 2 has a leak in the area of the air supply line 3, then the exhaust gases are sucked in by the combustion air blower 14 with the combustion air and thus can not get into the installation room.

Verfügt die Abgasleitung 2 im Bereich des Kaminschachts 6 über eine Undichtigkeit, so strömen die austretenden Abgase in die Ringleitung 11. Bei laufendem Abluftventilator 5 werden die austretenden Abgase mit der nachströmenden Luft über die Öffnung 8 des Kaminschachts 6 in die Umgebung 16 abgeleitet. Beim Stillstand des Abluftventilators 5 strömen die austretenden Abgase aus dem Abgasrohr 2 ebenfalls in die Ringleitung 11 und werden über den thermischen Auftrieb in die Umgebung 16 abgeleitet. Da das Heizgerät 1 die Verbrennungsluft über das Lüftungsgitter 4 aus dem Inneren des Hauses 7 ansaugt, kommt es zu keiner Rückströmung der austretenden Abgase in das Innere des Hauses 7.If the exhaust pipe 2 in the region of the chimney shaft 6 has a leak, the exiting exhaust gases flow into the ring line 11. When the exhaust fan 5 is running, the exiting exhaust gases are discharged into the environment 16 via the opening 8 of the chimney shaft 6 with the inflowing air. When the exhaust fan 5 stops, the exiting exhaust gases from the exhaust pipe 2 also flow into the loop 11 and are discharged into the environment 16 via the thermal buoyancy. Since the heater 1 sucks the combustion air through the ventilation grille 4 from the interior of the house 7, there is no backflow of the exiting exhaust gases in the interior of the house. 7

Zum Funktionieren der Haus- oder Wohnungslüftung ist die Luftzufuhrleitung 3 in Form einer Leitung koaxial zum Abgasrohr 2 nicht zwingend notwendig, weshalb auch eine andere Luftzufuhrleitung 3 erfindungsgemäß möglich ist. Die koaxiale Leitung ist jedoch sinnvoll, um Wärme vom Abgasrohr zurückzugewinnen und um - wie bereits erwähnt - bei Leckagen des Abgasrohres 2 einen Abgasaustritt in den Aufstellraum zu vermeiden.For the functioning of the home or apartment ventilation, the air supply line 3 in the form of a line coaxial with the exhaust pipe 2 is not absolutely necessary, which is why another air supply line 3 according to the invention is possible. However, the coaxial line is useful to recover heat from the exhaust pipe and - as already mentioned - to avoid leaks in the exhaust pipe 2 an exhaust gas outlet into the installation room.
