Abstract
Description
Die Erfindung betrifft ein Verfahren zur Regelung der Zirkulationspumpe in Anlagen zur Warmwasserversorgung in Gebäuden.The invention relates to a method for regulating the circulation pump in systems for hot water supply in buildings.
Es ist bekannt, daß die Warmwasserverteilung in Gebäuden zur Wassereinsparung und Verbesserung der Nutzung mit Zirkulationsleitungen und Pumpen ausgestattet sind; diese Pumpen werden zur Energieeinsparung geregelt.It is known that the hot water distribution in buildings for saving water and improving use with circulation pipes and pumps are equipped; these pumps are used to save energy regulated.
Im einfachsten Fall wird die Zirkulationspumpe über ein Zeitrelais gesteuert. Die Anforderung erfolgt über einen Taster, nach Ablauf der voreingestellten Pumpenlaufzeit schattet die Pumpe ab.In the simplest case, the circulation pump is over one Time relay controlled. The request is made via a button after the expiry the pump shades the preset pump runtime.
Um die Zirkulationspumpe zu regeln, werden ferner zeit- und temperaturgeführte Regelsysteme eingesetzt.To control the circulation pump, time and temperature-controlled control systems are also used.
Innerhalb eines oder mehrerer, von einer Zeitschaltuhr vorgegebenen Zeitfenster wird die Pumpe eingeschaltet. Das im Wärmetauscher erwärmte Wasser wird zu der Zapfstelle gepumpt und über eine Rücklaufleitung dem Wärmetauscher wieder zugeführt. Dort wird es erneut erwärmt und zirkuliert innerhalb des Zeitfensters im Rohrleitungssystem.Within one or more of the pump is switched on according to a time window predetermined time window. That in the heat exchanger heated Water is pumped to the tap and to the heat exchanger via a return line fed again. There it is reheated and circulates in the pipe system within the time window.
Nachteilig an diesem Verfahren ist der hohe Energieverlust in der Leitung, sowie die elektrischen Verluste der Pumpe.This method is disadvantageous the high energy loss in the line, as well as the electrical losses the pump.
Weiterhin ist eine Vorrichtung bekannt, in der die Zirkulation zusätzlich über einen Thermostaten an der Zirkulationsleitung gesteuert wird. Innerhalb eines Zeitfensters wird die Zirkulationspumpe angesteuert. Ist die Rohrleitungs-/Wassertemperatur größer als eine voreingestellte Solltemperatur schaltet die Zirkulationspumpe ab; unterschreitet die Rohrleitungstemperatur eine weitere voreingestellte Solltemperatur (Hysterese) schaltet die Zirkulationspumpe wieder ein.Furthermore, a device is known in which the circulation is also via a Thermostats on the circulation line is controlled. Within a The circulation pump is activated in the time window. Is the pipe / water temperature larger than the circulation pump switches a preset target temperature from; the pipe temperature falls below a further preset The circulation pump switches the set temperature (hysteresis) again on.
Weiterhin ist ein Verfahren bekannt, nachdem über einen mechanischen Strömungsgeber der Bedarf über die Wasserentnahme an der Zapfstelle erfaßt wird. Die durch die Entnahme verursachte Strömung wird über einen mechanischen Geber erfaßt und der Pumpensteuerung zugeführt. Die Pumpe wird eingeschaltet und nach einem der oben beschriebenen Verfahren abgeschaltet. Eine zeitgebundene Einschaltsperre vermindert die Zahl der falschen Pumpintervalle aufgrund von Druckschwankungen in Verbindung mit Luft im Versorgungsnetz.A method is also known after about a mechanical flow sensor the need about the water withdrawal is recorded at the tap. The by the removal caused flow is about detected a mechanical encoder and fed to the pump control. The pump is switched on and according to one of the above Procedure switched off. A time-based lockout is reduced the number of incorrect pumping intervals due to pressure fluctuations in connection with air in the supply network.
Nachteilig an diesen Verfahren ist die nicht bedarfsorientierte Steuerung der Zirkulationspumpe zum einen und die Kosten, sowie die sichere Funktion der vorzugsweise mechanischen Geber zum anderen.A disadvantage of this method is the non-demand-oriented control of the circulation pump for one and the cost, as well as the safe functioning of the preferred mechanical encoder to the other.
Die Erfindung mit den kennzeichnenden Merkmalen der Ansprüche hat demgegenüber die Vorteile, daß keinerlei mechanische Bauteile eingesetzt werden, Montagezeiten verkürzt und eine eindeutige Bedarfsregelung mit vermindertem Energiebedarf der Zirkulationspumpe gewährleistet ist.The invention with the characteristic features of claims has against it the advantages that none mechanical components are used, assembly times shortened and a clear need regulation with reduced energy consumption of the Circulation pump guaranteed is.

Nach einer weiteren, vorteilhaften Ausgestaltung der Erfindung wird die Zirkulationspumpe eingeschaltet, wenn der Gradient (n-te Ableitung) der Temperatur nach der Zeit einen voreingestellten Wert überschreitet.After another advantageous one Embodiment of the invention, the circulation pump is switched on if the gradient (nth derivative) of temperature over time exceeds a preset value.
Das Verfahren vermindert die Laufzeit der Zinkulationspumpe und deren Energieaufnahme, weil im Falle einer warmen Vorlaufleitung der Diffenernzenquotient/Gradient den Schwellwert nicht überschreitet und die Pumpe abgeschaltet bleibt.The procedure reduces the runtime the calculation pump and its energy consumption, because in the case of a warm flow line of the difference / gradient the threshold does not exceed and the pump remains switched off.
