Abstract

The method involves controllably switching on and off of a burner (3), and detecting actual pressure data of a pressure sensor (4) by a heating circuit (2). An integrative pressurized average value is formed from the detected actual pressure data during switching on of the burner. The pressurized average value and a pressurized reference value are compared with each other from a temperature reference value of a heating boiler (5) or from an operating time-reference value of the burner, where the heating boiler is connected to the heating circuit.

Description

Die Erfindung betrifft ein Verfahren zur Erkennung eines defekten Membranausdehnungsgefäßes in einem Heizkreis mit einem Brenner gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for detecting a defective membrane expansion vessel in a heating circuit with a burner according to the preamble of patent claim 1.

Ein Verfahren zur Erkennung eines defekten Membranausdehnungsgefäßes in einem Heizkreis mit einem Brenner ist nach der DE 101 60 327 A1 bekannt. Wie üblich, wird dieser Brenner während des Betriebs der Anlage ein- und ausgeschaltet. Dabei steigt und fällt der Druck im Heizkreis, wobei mittels eines entsprechenden Drucksensors die aktuellen Druckdaten ermittelbar sind. Nachteilig an dieser Lösung ist, dass zur Erkennung eines Defekts (zum Beispiel gasseitige Entleerung) am Membranausdehnungsgefäß dieses vollständig entleert werden muss.A method for detecting a defective membrane expansion vessel in a heating circuit with a burner is according to the DE 101 60 327 A1 known. As usual, this burner will be turned on and off during operation of the system. In this case, the pressure in the heating circuit rises and falls, wherein the current pressure data can be determined by means of a corresponding pressure sensor. A disadvantage of this solution is that to detect a defect (for example, gas side emptying) on the diaphragm expansion vessel this must be completely emptied.

Der Erfindung liegt dementsprechend die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu verbessern.The invention is therefore an object of the invention to improve a method of the type mentioned.

Diese Aufgabe ist mit einem Verfahren der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved by a method of the type mentioned by the features listed in the characterizing part of patent claim 1.

Nach der Erfindung ist also vorgesehen, dass aus den bei eingeschaltetem Brenner 3 ermittelten Druckdaten ein Druckmit-telwert gebildet und dieser mit einem Druckreferenzwert verglichen wird.According to the invention, it is thus provided that from the pressure data determined when the burner 3 is switched on, a pressure average is formed and this pressure is compared with a pressure reference value.

Im Unterschied zum vorgenannten Stand der Technik kann somit die einwandfreie Funktion des Membranausdehnungsgefäßes bei laufender Anlage, was unten noch ausführlich erläutert wird, kontinuierlich überwacht werden. Eine Kontrollentleerung des Membranausdehnungsgefäßes ist entbehrlich.In contrast to the aforementioned prior art, the proper functioning of the membrane expansion vessel can thus be continuously monitored while the system is running, as will be explained in detail below. A control evacuation of the expansion vessel is dispensable.

Andere vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the method according to the invention will become apparent from the dependent claims.

Der Vollständigkeit halber wird noch auf die DE 103 35 310 B3 hingewiesen, bei der die Funktionsfähigkeit des Membranausdehnungsgefäßes aber nicht unter Berücksichtigung des Betriebszustandes des Brenners überwacht wird.The sake of completeness is still on the DE 103 35 310 B3 pointed out, in which the functionality of the membrane expansion vessel but is not monitored taking into account the operating condition of the burner.

Das erfindungsgemäßen Verfahren einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines Ausführungsbeispiels näher erläutert.The inventive method including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of an embodiment.

a pressure curve p [for example in bar] is plotted over time t [s] for intact and defective membrane expansion vessels (MAG).

Die in Figur 1 dargestellte Heizungsanlage besteht aus einem Heizkessel 5 mit Brenner 3 und einer Regeleinheit 6. An den Heizkessel 5 ist ein Heizkreis 2 angeschlossen, der in bekannter Weise mit einem Membranausdehnungsgefäß 1 und einem Drucksensor 4 versehen ist. Die Erfindung betrifft ein Verfahren zum Betrieb dieser Heizungsanlage, und zwar insbesondere ein Verfahren zur Erkennung eines Defekts am Membranausdehnungsgefäß 1.In the FIG. 1 shown heating system consists of a boiler 5 with burner 3 and a control unit 6. To the boiler 5, a heating circuit 2 is connected, which is provided in a known manner with a membrane expansion vessel 1 and a pressure sensor 4. The invention relates to a method for operating this heating system, in particular a method for detecting a defect in the membrane expansion vessel. 1

Ein solches Membranausdehnungsgefäß 1 dient dazu, Druckschwankungen im Heizkreis 2 auszugleichen. Diese entstehen zum Beispiel beim Ein- bzw. Ausschalten des Brenners 3, da eine Temperaturänderung des Heizkreismediums unmittelbar zu einer Druckänderung im geschlossenen Heizkreis 2 führt. Das Membranausdehnungsgefäß 1 besteht in bekannter Weise aus zwei Volumina, zwischen denen eine elastische Membran angeordnet ist. Das eine, mit dem Heizkreis 2 verbundene Volumen ist mit Heizkreiswasser gefüllt, das andere mit Gas, wobei das zweite Volumen nach außen abgedichtet ist und zusammen mit der Membran wie eine Gasfeder für das Wasservolumen wirkt.Such a membrane expansion vessel 1 serves to compensate for pressure fluctuations in the heating circuit 2. These arise for example when switching on and off of the burner 3, since a temperature change of the heating medium medium leads directly to a pressure change in the closed heating circuit 2. The membrane expansion vessel 1 consists in a known manner of two volumes, between which an elastic membrane is arranged. One connected to the heating circuit 2 volume is filled with Heizkreiswasser, the other with gas, the second volume is sealed to the outside and acts together with the membrane like a gas spring for the volume of water.

Für das erfindungsgemäße Verfahren ist nun wesentlich, dass aus den bei eingeschaltetem Brenner 3 ermittelten Druckdaten ein Druckmittelwert pM gebildet und dieser mit einem Druckreferenzwert pR verglichen wird.For the method according to the invention, it is now essential that from the pressure data determined when the burner 3 is switched on, a pressure average value p M is formed and this pressure is compared with a pressure reference value p R.

Dieses Verfahren basiert auf der Erkenntnis, dass ungewöhnliche hohe Druckdifferenz im Heizkreis 2 beim Ein- und Ausschalten des Brenners 3 ein Zeichen für ein defektes Membranausdehnungsgefäß 1 sind, und zwar weil ein Defekt des Membranausdehnungsgefäßes 1 vor allem darin besteht, dass gasseitig ein Leck (am Gehäuse des Gefäßes oder auch der Membran) auftritt und damit die Federwirkung des Gasvolumens aufgehoben wird.This method is based on the finding that unusual high pressure difference in the heating circuit 2 when switching on and off the burner 3 is a sign of a defective membrane expansion vessel 1, namely because a defect of the expansion vessel 1 mainly consists in that a leak (on Housing of the vessel or the membrane) occurs and thus the spring action of the gas volume is released.

Die Figuren 2 und 3 verdeutlichen diesen Zusammenhang. Figur 2 zeigt zwei Brennerläufe (0: Brenner aus, 1: Brenner an), wobei das Membranausdehnungsgefäß 1 (MAG) im ersten Brennerlauf intakt und im zweiten Brennerlauf defekt ist, was sich allerdings erst aus der Analyse der Figur 3 ergibt: Diese zeigt links einen ersten Druckverlauf, bei dem der Druck, sobald der Brenner eingeschaltet wird, erwartungsgemäß ansteigt, und zwar so lange, wie der Brenner läuft. Nach dem Abschalten fällt der Druck wieder ab. Mit pM1 ist in Figur 3 der sich aus der ersten, linken Kurve ergebende Druckmittelwert benannt, der unterhalb des ebenfalls angegebenen Druckreferenzwertes pR liegt. Dieser Druckmittelwert pM wird bevorzugt durch entsprechende integrative Mittelwertbildung der Druckkurve von einer entsprechenden Software rechnerisch ermittelt. Aber auch andere Mittelwertbildungsalgorithmen kommen in Betracht.The FIGS. 2 and 3 illustrate this connection. FIG. 2 shows two burner runs (0: burner off, 1: burner on), wherein the membrane expansion vessel 1 (MAG) intact in the first burner run and defective in the second burner run, which, however, only from the analysis of FIG. 3 shows: This shows on the left a first pressure curve, with which the pressure, as soon as the burner is switched on, rises as expected, as long as the burner runs. After switching off, the pressure drops again. With p M1 is in FIG. 3 arising from the first, Named the left curve resulting pressure mean, which is below the pressure reference value p R also indicated. This pressure mean value p M is preferably calculated by corresponding integrative averaging of the pressure curve by a corresponding software. But other averaging algorithms come into consideration.

Betrachtet man im Vergleich dazu die zweite, rechte Kurve in Figur 3, so fällt auf, dass dort der Druck während des Brennerlaufs deutlich stärker ansteigt als beim ersten Brennerlauf. Insbesondere ist der sich dabei ergebende Druckmittelwert pM2 deutlich höher; er liegt auch deutlich oberhalb des Druckreferenzwertes pR, was erfindungsgemäß auf einen Defekt am Membranausdehnungsgefäß schließen lässt.If you look at the second, right-hand curve in FIG. 3 , it is noticeable that the pressure increases significantly more during the burner run than during the first burner run. In particular, the resulting pressure average p M2 is significantly higher; it is also well above the pressure reference value p R , which can be inferred according to the invention to a defect in the membrane expansion vessel.

Ist also der Druckmittelwert pM größer als oder gleich dem Druckreferenzwert pR wird diese Information (Defekt am Membranausdehnungsgefäß 1 - Sicherheitsrisiko für die gesamte Heizungsanlage!) vorzugsweise optisch und/oder akustisch signalisiert, und zwar besonders bevorzugt und wie in Figur 1 dargestellt über eine am Heizkessel 5 vorgesehene Regeleinheit 6. Diese wird darüber hinaus auch zur Hinterlegung des Druckreferenzwertes pR verwendet.Thus, if the mean pressure value p M is greater than or equal to the pressure reference value p R , this information (defect in the membrane expansion vessel 1 - safety risk for the entire heating system!) Is preferably optically and / or acoustically signaled, and particularly preferably and as in FIG. 1 represented by a provided on the boiler 5 control unit 6. This is also used to deposit the pressure reference value p R.

Weiterhin ist bevorzugt vorgesehen, dass der Druckmittelwert pM wahlweise erst ab einem Temperaturreferenzwert TR (der auch in der Regeleinheit 5 hinterlegt sein kann) eines an den Heizkreis 2 angeschlossenen, mit dem Brenner 3 versehenen Heizkessels 5 oder ab einem Laufzeitreferenzwert tR des Breners 3 mit dem Druckreferenzwert pR verglichen wird. Die Maßgabe, die aktuelle Temperatur T des Heizkessels 5 mit einem Temperaturreferenzwert TR zu vergleichen, berücksichtigt, dass bei einer kurzen Brennerlaufzeit bzw. entsprechend niedriger Energiezufuhr zum Heizkreis der Druck regelmäßig nur relativ wenig ansteigt und ein Defekt am Membranausdehnungsgefäß 1 dementsprechend bei einem solchen Betriebszustand praktisch nicht zu erkennen ist. In vergleichbarer Weise ist ein Defekt am Membranausdehnungsgefäß 1 nur dann zu ermitteln, wenn der Brenner 3 überhaupt eine gewisse Zeit (Laufzeitreferenzwert tR) eingeschaltet war, da eine zu kurze Brennerlaufzeit (zum Beispiel, wenn dieser im Taktbetrieb läuft) nicht zu einem für die Defekterkennung relevanten Druckanstieg im Heizkreis 2 führt.Furthermore, it is preferably provided that the pressure mean value p M optionally only from a temperature reference value T R (which may be stored in the control unit 5) connected to the heating circuit 2, provided with the burner 3 boiler 5 or from a term reference value t R of the Breners 3 is compared with the pressure reference value p R. The proviso to compare the current temperature T of the boiler 5 with a temperature reference value T R , takes into account that with a short burner run time or correspondingly low energy supply to the heating circuit, the pressure regularly increases only relatively little and Accordingly, a defect on the membrane expansion vessel 1 is practically invisible in such an operating state. In a similar way, a defect in the diaphragm expansion vessel 1 can only be determined if the burner 3 has been switched on for a certain amount of time (term reference value t R ), since too short a burner running time (for example if it runs in cyclic operation) does not lead to one for the Defect detection relevant increase in pressure in the heating circuit 2 leads.

Um die Heizungsanlage flexibel betreiben und an entsprechende Umgebungssituationen anpassen zu können, ist schließlich bevorzugt vorgesehen, dass wahlweise der Druckreferenzwert pR und/oder der Temperaturreferenzwert TR vorzugsweise an der Regeleinheit 6 einstellbar ist bzw. sind.In order to be able to operate the heating system flexibly and to be able to adapt it to corresponding environmental situations, it is finally preferably provided that the pressure reference value p R and / or the temperature reference value T R is or are preferably adjustable on the control unit 6.
