Definitions
- 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.
- 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.
- the invention is therefore an object of the invention to improve a method of the type mentioned.
- 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.
- heating system consists of a boiler 5 with burner 3 and a control unit 6.
- 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.
- 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. The one connected to the heating circuit 2 volume is filled with Edelnikwasser, 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.
- 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.
- 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:
- 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.
- this information (defect in the membrane expansion vessel 1 - security 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.
- the pressure average 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.
- T R which may be stored in the control unit 5
- 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.
- 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 when it runs in cyclic operation) does not lead to a for the Defect detection relevant increase in pressure in the heating circuit 2 leads.
- the pressure reference value p R and / or the temperature reference value T R is or are preferably adjustable on the control unit 6.

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
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
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

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
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 average p M optionally only from a temperature reference value T R (which may be stored in the control unit 5) connected to the
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 optionally the pressure reference value p R and / or the temperature reference value T R is or are preferably adjustable on the
