Abstract
Description
Die Erfindung betrifft einen Gasheizkessel nach dem Oberbegriff des Patentanspruches 1 sowie ein Verfahren zum Betreiben desselben. Gasheizkessel besitzen üblicherweise eine getrennte Zuluft- und Abgasführung. Die Zuluft gelangt durch separate Zuluftschächte oder durch Wandöffnungen in den Aufstellungsraum. Die Abgase werden durch einen Schornstein ins Freie geführt.The invention relates to a gas boiler according to the preamble of Claim 1 and a method for operating the same. Gas boilers usually have separate supply air and exhaust gas routing. The supply air enters through separate supply air ducts or through wall openings Installation room. The exhaust gases are led outside through a chimney.
Gasheizkessel können auch ohne einen Anschluß an einen Schornstein betrieben werden. Die Abgase sind in diesem Fall über baurechtlich zugelassene Abgasleitungen durch die Wand oder das Dach nach außen zu führen. Solche Anschlüsse sind speziell bei dezentralen Heizungsanlagen zu empfehlen und auch in Gebäuden, in denen kein geeigneter Schornstein vorhanden ist. Dabei ist es bekannt, eine kombinierte Zuluft-/Abgasführung vorzusehen. Der Zuluftkanal bildet mit dem Abgaskanal eine bauliche Einheit, die bereits vom Hersteller mitgeliefert werden kann. Auf die Funktionsweise des Gasheizkessels haben diese Baueinheiten keinen Einfluß. Sie dienen jedoch einer schnelleren und einfacheren Montage. Außerdem erfolgt eine gewisse Vorwärmung der einströmenden Zuluft durch Wärmetausch mit den fortströmenden Abgasen, was die Verbrennungsergebnisse verbessert.Gas boilers can also be operated without being connected to a chimney become. In this case, the exhaust gases are approved by building law Lead exhaust pipes through the wall or roof to the outside. Such Connections are especially recommended for decentralized heating systems and also in Buildings in which there is no suitable chimney. It is known to provide a combined supply air / flue gas routing. The supply air duct forms with the Exhaust duct is a structural unit that is already supplied by the manufacturer can. These units have no function on the gas boiler Influence. However, they serve a faster and easier assembly. Furthermore the incoming air is preheated to a certain extent by heat exchange the exhaust gases flowing away, which improves the combustion results.
Die Kesselwassertemperatur von Heizkesseln wird üblicherweise über eine die Leistung bestimmende Größe geregelt. Als Größe empfiehlt sich die Außentemperatur. Eine höhere Außentemperatur erfordert einen geringeren Wärmebedarf und führt deshalb zu einer niedrigeren Kesselwasser- bzw. Vorlauftemperatur. Bei niedrigeren Außentemperaturen wird mehr Wärme angefordert, so daß höhere Kesselwasser- bzw. Vorlauftemperaturen nötig sind. Für eine Regelung dieser Art ist ein Außentemperaturfühler erforderlich. Dieser wird bisher vom Heizungsbauer an einer geeigneten Stelle an der Außenwand des Gebäudes angebracht und mit dem Regelgerät verdrahtet. Hierfür ist ein gewisser Aufwand erforderlich, der besonders bei Altbauten schwierig durchzuführen ist.The boiler water temperature of boilers is usually the one Performance-determining variable regulated. The size is recommended Outside temperature. A higher outside temperature requires a lower one Heat demand and therefore leads to a lower boiler water or Flow temperature. At lower outside temperatures there is more heat requested, so that higher boiler water or flow temperatures are necessary. For A regulation of this type requires an outside temperature sensor. This will previously by the heating engineer at a suitable location on the outer wall of the Building attached and wired to the control device. There is a certain for this Effort required, which is particularly difficult to carry out in old buildings.
Der Erfindung liegt die Aufgabe zugrunde, für einen Gasheizkessel mit einer kombinierten Zuluft-/Abgasführung die Montage des Außentemperaturfühlers wesentlich zu vereinfachen und zu verbilligen.The invention is based, for a gas boiler with an object Combined supply air / flue gas routing the installation of the outside temperature sensor to simplify and cheapen considerably.
Erfindungsgemäß erfolgt dieses durch das im Kennzeichen des Patentanspruches 1 genannte Merkmal.According to the invention, this is done by the characterizing part of patent claim 1 mentioned feature.
Der Fühler wird nicht mehr in weiter Entfernung vom Heizkessel an der Außenwand angeordnet, sondern im Kessel, und zwar direkt am Eintritt des Zuluftkanales. Somit kann der Fühler werksseitig montiert und mit dem Regler verbunden werden. Sämtliche Montagearbeiten durch den Heizungsbauer entfallen. Es ist auch keine Verdrahtung mehr erforderlich, was speziell in Altbauten von Vorteil ist, die mit mehreren Kleinkesseln dieser Art ausgerüstet werden sollen.The sensor is no longer on the outer wall from the boiler arranged, but in the boiler, directly at the inlet of the supply air duct. The sensor can thus be assembled at the factory and connected to the controller. All installation work by the heating engineer is omitted. It is not one either Wiring required more, which is particularly advantageous in old buildings with several small boilers of this type are to be equipped.
Da sich über die Länge des Zuluftkanales eine gewisse Temperaturanhebung der eintretenden Außenluft ergeben kann, ist eine Korrekturrechnung zu empfehlen, um die tatsächliche Außentemperatur zu ermitteln. Die Korrekturformel ist von der Länge des Zuluftkanales abhängig.Because there is a certain temperature increase over the length of the supply air duct outside air, a correction calculation is recommended to to determine the actual outside temperature. The correction formula is from Length of the supply air duct depends.
Brauchbare Ergebnisse sind nur dann zu erzielen, wenn der Fühler voll von der einströmenden Frischluft beaufschlagt wird und wenn diese nicht im Gegenstrom von heißen Abgasen aufgeheizt wird. Die geeignete Situation ist dann vorhanden, wenn der Brenner vor dem Brennerstart durchgespült wird. Dann liegt am Eintritt des Zuluftkanales in den Kessel weder die Raumtemperatur, wie nach einer längeren Stillstandsphase, noch eine verfälschte Temperatur, wie während des Brennerbetriebes, vor. Useful results can only be achieved if the sensor is full of incoming fresh air is applied and if this is not in counterflow is heated by hot exhaust gases. The appropriate situation is then available if the burner is flushed out before starting the burner. Then it's up to the entrance of the supply air duct in the boiler neither the room temperature, as after a longer period Standstill phase, still a distorted temperature, like during the Burner operation, before.
Ohne weitläufige Verkabelung ist eine außentemperaturgeführte Regelung der Kesselwasser- bzw. Vorlauftemperatur möglich. Es muß nur darauf geachtet werden, daß tatsächlich der voll einströmende, kühle Zuluftstrom erfaßt wird.Without extensive wiring, outside temperature-controlled regulation is the Boiler water or flow temperature possible. You just have to take care that the fully incoming, cool supply air flow is actually detected.
Die Zeichnung stellt in einer einzigen Figur einen senkrechten Schnitt durch ein Gebäude mit vier separat beheizten Räumen dar.The drawing shows a vertical section through in a single figure Building with four separately heated rooms.
In jedem der Räume ist ein eigener Gasheizkessel 1 mit einer kombinierten Zuluft- /Abgasführung angeordnet. Der Zuluftkanal 2 und der Abgaskanal 3 bilden eine Baueinheit, die durch einen Mauerkasten 4 durch das Dach 5 bzw. die Außenwand 6 geführt sind. Die Kanäle 2, 3 sind dabei in- oder nebeneinander angeordnet. Im Gasheizkessel 1, und zwar direkt am Eintritt des Zuluftkanales 2, sitzt jeweils ein Temperaturfühler 8. Dieser mißt die Temperatur der eintretenden Zuluft. Je nach Länge des Zuluftkanales 2 erfolgt eine Korrektur des gemessenen Wertes. Die so bestimmte Temperatur gilt dann als vorliegende Außentemperatur, anhand der die Regelung vorgenommen wird.Each of the rooms has its own gas boiler 1 with a combined supply air / flue gas system. The supply air duct 2 and the exhaust duct 3 form a structural unit which are guided through a wall box 4 through the roof 5 and the outer wall 6 , respectively. The channels 2 , 3 are arranged inside or next to each other. A temperature sensor 8 is located in the gas boiler 1 , directly at the inlet of the supply air duct 2 . This measures the temperature of the incoming air. Depending on the length of the supply air duct 2 , the measured value is corrected. The temperature determined in this way then applies as the existing outside temperature on the basis of which the control is carried out.
