Description
Die Erfindung betrifft ein Verfahren zum Ansteuern einer Zirkulationspumpe nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a method for driving a circulation pump according to the preamble of claim 1.
Zirkulationsleitungen stellen die Verbindung der Warmwasserentnahmeleitung zurück zum Speicher dar. Der somit entstandene geschlossene Kreislauf hat die Aufgabe, immer Warmwasser in den Leitungen zu führen, damit bei jedem Zapfvorgang möglichst schnell auch Warmwasser gezapft werden kann. Ohne Zirkulationsleitung müsste erst das abgekühlte Wasser abfließen, bevor warmes verfügbar ist. Besonders für größere Anlagen, wie zum Beispiel Mehrfamilienwohnhäuser oder Hotels, sind Zirkulationsleitungen unverzichtbar. Sie verbessern den Warmwasserkomfort, reduzieren den Wasserverbrauch und ermöglichen eine thermische Desinfektion auch im Rohrnetz.circulation pipes put the connection of the hot water extraction line back to the tank The resulting closed cycle has the task of always carry hot water in the pipes, so with each tap preferably hot water can also be tapped quickly. Without circulation pipe should first the cooled Drain water, before warm is available. Especially for larger plants, such as multi-family residences or hotels, are circulation conduits indispensable. They improve the hot water comfort, reduce the water consumption and allow a thermal disinfection also in the pipe network.
Üblicherweise wird die aktuelle Warmwassertemperatur mit einem Temperaturfühler im oberen Bereich des Warmwasserspeichers erfasst und der Sollwert für die Warmwassertemperatur im oberen Bereich des Warmwasserspeichers am Regler eines Heizgerätes eingegeben. Er entspricht einer Ausschalttemperatur, die über eine Schalthysterese mit einer Einschalttemperatur, d. h. dem Beginn der Nachladung, in Zusammenhang steht.Usually is the current hot water temperature with a temperature sensor in the upper range of the hot water tank detected and the setpoint for the Hot water temperature in the upper area of the hot water tank on Regulator of a heater entered. It corresponds to a switch-off temperature, which over a Switching hysteresis with a switch-on temperature, d. H. the beginning recharging, related.
Für einen günstigen Wirkungsgrad einer Heizungsanlage ist unter anderem auch wichtig, dass einerseits ein ausreichender Warmwasserkomfort zur Verfügung steht und andererseits der Warmwasserspeicher aber nur bei tatsächlichem Warmwasserbedarf aufgeheizt wird, um Auskühlungs- bzw. Bereitschaftsverluste möglichst klein zu halten.For one Great Efficiency of a heating system is also important, among other things that, on the one hand, sufficient hot water comfort is available and on the other hand, the hot water tank but only in fact Hot water demand is heated to Auskühlungs- or standby losses preferably to keep small.
Eine Zirkulationspumpe wird üblicherweise in vorgegebenen und/oder am Regler einstellbaren Zeitintervallen in Betrieb gesetzt. Es ist bekannt, die Freigabe der Warmwasserbereitung an die eingestellten Heizzeiten für angeschlossene Heizkreise zu koppeln oder wahlweise mindestens einen an einem Regler einzugebenden Zeitraum für die Freigabe der Nachladung des Warmwasserspeichers vorzusehen. Dann läuft die Zirkulationspumpe nur im Zeitraum der Freigabe. Ist dieser Zeitraum sehr großzügig bemessen und weicht er deutlich vom tatsächlichen Warmwasserbedarf und dem Entnahmeverhalten ab, so treten Energieverluste auf. Die Ursache liegt im Wesentlichen im Durchmischen des Warmwasserspeichers und einer möglicherweise unnötig ausgelösten Nachladung, weil ein Temperaturgrenzwert dafür im Warmwasserspeicher unterschritten wurde. Dann wird jeweils ein unnötiger Brennerstart mit entsprechendem Energieverbrauch verursacht und das Temperaturniveau im Warmwasserspeicher wieder angehoben, obwohl keine Zapfung folgt.A Circulation pump is commonly used in predetermined and / or adjustable on the controller time intervals in Operation set. It is known the release of water heating to the set heating times for connected heating circuits to couple or optionally at least one to be entered on a controller Period for to provide the release of the recharging of the hot water tank. Then is running? Circulation pump only in the period of release. Is this period very generous and he deviates significantly from the actual Hot water demand and the withdrawal behavior, so occur energy losses on. The cause lies mainly in the mixing of the hot water tank and one possibly unnecessary triggered recharge, because a temperature limit for it was undercut in the hot water tank. Then one each unnecessary Burner startup with corresponding energy consumption caused and the temperature level in the hot water tank raised again, though no tapping follows.

Der Erfindung liegt daher die Aufgabe zugrunde, den Wirkungsgrad einer Heizungsanlage zu optimieren und die Durchmischung eines Warmwasserspeichers durch den Betrieb einer Zirkulationspumpe in Zeiten ohne Warmwasserentnahme zu vermindern.Of the The invention is therefore based on the object, the efficiency of a Optimize heating system and the mixing of a hot water tank by the operation of a circulation pump in times without hot water withdrawal to diminish.
Erfindungsgemäß wird dies mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.According to the invention this is solved with the features of claim 1. Advantageous developments are the dependent claims refer to.
Das Verfahren zum Ansteuern einer Zirkulationspumpe ist dadurch gekennzeichnet, dass ein weiterer Temperaturfühler zur Erfassung der Warmwassertemperatur in der Warmwasserentnahmeleitung mit Abstand zum Warmwasserspeicher in der Warmwasserentnahmeleitung angeordnet ist. Es erfolgt ein Vergleich der Messwerte der beiden Temperaturfühler und die Zirkulationspumpe wird dann beim Erreichen und/oder Überschreiten eines vorzugebenden Schwellwertes für die Temperaturdifferenz in Betrieb gesetzt. Ergänzend oder alternativ dazu kann beim Erreichen und/oder Überschreiten eines Schwellwertes für die Temperaturdifferenz auch eine Nachladung des Warmwasserspeichers erfolgen.The Method for controlling a circulation pump is characterized in that that another temperature sensor for recording the hot water temperature in the hot water extraction pipe with distance to the hot water tank in the hot water extraction pipe is arranged. There is a comparison of the measured values of the two temperature sensor and the circulation pump will then reach and / or exceed a preset threshold for the temperature difference in Operation set. additional or alternatively, upon reaching and / or exceeding a threshold for the temperature difference also a recharge of the hot water tank respectively.
Generell wird ein Vergleich der Messwerte der beiden Temperaturfühler nur in Zeiträumen durchgeführt, in denen am Regler die Warmwasserbereitung freigegeben ist. Die Zirkulationspumpe wird in einer ersten Variante beim Erreichen und/oder Unterschreiten eines Schwellwertes für die Temperaturdifferenz wieder abgeschaltet oder sie wird in einer zweiten Variante ab dem Erreichen und/oder Überschreiten eines Schwellwertes für die Temperaturdifferenz für einen vorzugebenden Zeitraum in Betrieb gesetzt.As a general rule will be a comparison of the readings of the two temperature sensors only carried out in periods, in the hot water preparation is enabled on the controller. The circulation pump will in a first variant when reaching and / or falling short a threshold for the temperature difference is switched off again or it is in a second Variant from reaching and / or exceeding a threshold value for the Temperature difference for put into operation for a specified period of time.
Zur Durchführung des Verfahrens ist es wichtig, dass der zusätzliche Temperaturfühler für die Warmwassertemperatur in der Warmwasserentnahmeleitung mit Abstand einem zum Warmwasserspeicher in der Warmwasserentnahmeleitung angeordnet ist, um direkte Wärmeleitung zu vermeiden. Vorzugsweise sollte der Abstand zwischen Temperaturfühler und Warmwasserspeicher mindestens 30 cm betragen.to execution Of the procedure, it is important that the additional temperature sensor for the hot water temperature in the hot water extraction line at a distance to the hot water tank is arranged in the hot water extraction line to direct heat conduction to avoid. Preferably, the distance between the temperature sensor and Hot water tank should be at least 30 cm.
