Description
Die Erfindung betrifft eine Heizungsanlage gemäß dem Oberbegriff des Patentanspruchs 1 und ein Verfahren zum Betrieb einer Heizungsanlage nach dem Oberbegriff des Patentanspruchs 5.The invention relates to a heating system according to the preamble of patent claim 1 and a method for operating a heating system according to the preamble of patent claim 5.
Eine Heizungsanlage der eingangs genannten Art und ein Verfahren zu ihrem Betrieb sind seit Jahrzehnten bekannt, d. h. insoweit bedarf es keines besonderen druckschriftlichen Nachweises. Eine solche Heizungsanlage besteht aus einem Heizgerät zur Erwärmung eines fluiden Heizkreislaufmediums (in der Regel Wasser), wobei das Heizgerät über einer Vor- und einen Rücklaufanschluss hydraulisch mit einem das Heizkreislaufmedium führenden und mehrere Heizkörper aufweisenden Heizkreislauf verbunden ist. Die Heizkörper (auch Heizflächen genannt) sind dabei parallel oder seriell in den Heizkreislauf (oder auch die Heizkreisläufe) eingebunden. Um eine Nennheizleistung erbringen zu können, muss jede Heizfläche mit einem Nenn-Volumenstrom des Heizkreislaufmediums versorgt werden. Dabei benötigen Heizkörper mit größerer Leistung einen größeren Heizkreislaufmediumvolumenstrom als Heizflächen mit kleinerer Wärmeleistung. Außerdem ist zu beachten, dass jeder Heizkörper einen für ihn typischen Druckverlust zwischen seinem Ein- und Austritt aufweist, d. h. einem Heizkörper mit einem kleineren Druckverlust wird regelmäßig mehr Heizkreislaufmedium zugeführt als einem Heizkörper mit größerem Druckverlust. In der Praxis wird diesem Problem mit dem so genannten "hydraulischen Abgleich" der Anlage begegnet, der sicher stellen soll, dass jeder Heizkörper den für ihn vorgesehenen Nenn-Volumenstrom an Heizkreislaufmedium erhält.A heating system of the type mentioned and a method for their operation are known for decades, d. H. To this extent, no special documentary evidence is required. Such a heating system consists of a heater for heating a fluid heating circuit medium (usually water), wherein the heater via a feed and a return port is hydraulically connected to a heating circuit medium leading and having a plurality of heating radiator heating circuit. The radiators (also called heating surfaces) are parallel or serially involved in the heating circuit (or the heating circuits). In order to provide a rated heat output, each heating surface must be supplied with a nominal volume flow of the heating circuit medium. Here, radiators with greater power require a larger heating medium flow rate than heating surfaces with lower heat output. In addition, it should be noted that each radiator has a typical for him pressure loss between its inlet and outlet, d. H. a radiator with a smaller pressure loss is regularly fed more heating circuit medium than a radiator with greater pressure drop. In practice, this problem is addressed by the so-called "hydraulic balancing" of the system, which is intended to ensure that each radiator receives the nominal volume flow of heating circuit medium intended for it.
Bei der Neuinstallation von Heizungsanlage ist dieser hydraulische Abgleich noch relativ leicht zu bewerkstelligen, da bei Neuanlagen die Druckverluste der einzelnen Komponenten in der Regel bekannt sind bzw. sich die Gesamtanlage jedenfalls im wesentlichen rechnerisch erfassen läßt.When installing new heating system of this hydraulic balancing is still relatively easy to do, as with New installations, the pressure losses of the individual components are usually known or the entire system can be detected in any case substantially mathematically.
Deutlich problematischer ist der hydraulische Abgleich bei Altanlagen, die zum Beispiel mit einem neuen Heizgerät ausgestattet werden, da in diesem Fall typischerweise weder die Druckverluste der Heizkörper noch der Druckverlust des Heizkreises bekannt sind. - Um trotz der beschriebenen Problematik genügend Heizleistung an den Heizkörpern zur Verfügung stellen zu können, und zwar ohne vorher aufwendige Einzelmessungen durchgeführt zu haben (wozu meist aus Kostengründen nicht ausreichend Zeit zur verfügung steht), behilft man sich regelmäßig durch eine sehr hoch eingestellte Pumpenleistung (Schätzwert), die gewissermaßen einfach den stärksten Druckverlust ausgleicht.Significantly more problematic is the hydraulic balance in old systems, which are equipped for example with a new heater, since in this case typically neither the pressure losses of the radiator nor the pressure loss of the heating circuit are known. - In order to be able to provide sufficient heating power to the radiators despite the described problem, without having previously performed complex individual measurements (which is usually for cost reasons not enough time available), one manages regularly by a very high set pump performance ( Estimated value), which to a certain extent simply compensates for the greatest pressure loss.
Da dies natürlich einen unnötigen Energieverbrauch nach sich zieht, ist gemäß VOB (DIN 18380) vorgesehen, einen hydraulischen Abgleich so durchzuführen, dass "... bei bestimmungsgemäßem Betrieb, z. B. auch nach Raumtemperaturabsenkung oder Betriebspausen der Heizungsanlage, alle Wärmeverbraucher entsprechend ihrem Wärmebedarf mit Heizwasser versorgt werden".Since this naturally entails unnecessary energy consumption, according to VOB (DIN 18380) it is intended to carry out a hydraulic balancing so that "... under normal operation, eg also after lowering the room temperature or when the heating system is in operation, all heat consumers are in accordance with their requirements Heat requirement to be supplied with heating water ".
Eine mögliche Vorgehensweise zur Durchführung des hydraulischen Abgleichs ist in der
Aus der
Der Erfindung liegt die Aufgabe zugrunde, bei einer Heizungsanlage und bei einem Verfahren zum Betrieb einer Heizungsanlage der eingangs genannten Art die hydraulische Abstimmbarkeit der Komponenten zueinander zu verbessern bzw. zu vereinfachen.The invention is based on the object in a heating system and in a method for operating a heating system of the type mentioned to improve the hydraulic tunability of the components to each other or simplify the task.
Diese Aufgabe wird mit einer Heizungsanlage der eingangs genannten Art gegenständlich durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst. Verfahrensmäßig lösen die im Kennzeichen des Patentanspruchs 5 aufgeführten Merkmale diese Aufgabe.This object is achieved with a heating system of the type mentioned objectively by the features listed in the characterizing part of patent claim 1. Technically solve the features listed in the characterizing part of claim 5 this task.
Nach der Erfindung ist gegenständlich also vorgesehen, dass das Heizgerät zur Durchführung eines hydraulischen Abgleichs der Heizungsanlage mit Mitteln zur Erfassung und Anzeige des vom Heizgerät bereitgestellten Heizkreislaufmedium-Volumenstroms und mit Mitteln zur Erfassung und Anzeige der Druckdifferenz zwischen dem Vor- und dem Rücklaufanschluss versehen ist.According to the invention is thus representatively provided that the heater for performing a hydraulic balancing of the heating system is provided with means for detecting and displaying the heater provided by the heating medium flow rate and means for detecting and displaying the pressure difference between the supply and the return port.
Mit anderen Worten ausgedrückt, ist erfindungsgemäß vorgesehen, das Heizgerät schon ab Werk mit zwei Messvorrichtungen (zur Druck- und Volumenstrommessung) auszustatten, mit deren Hilfe ein hydraulischer Abgleich jeder Zeit und zwar auch ohne weiteren speziellen Messaufbau möglich ist. Im Ergebnis wird dabei erreicht, dass alle Heizkörper bei Nenn-Volumenstrom betrieben werden, wobei die durch die Drosseleinrichtungen vcrgegebenen Druckverluste so gering wie möglich sind.In other words, according to the invention, the heater is already equipped ex works with two measuring devices (for pressure and flow measurement), with the help of a hydraulic adjustment of each time and indeed without further special measurement setup is possible. As a result, it is achieved that all radiators are operated at nominal volume flow, whereby the pressure losses through the throttle devices are as low as possible.
Dieser Abgleich erfolgt mit der erfindungsgemäßen Heizungsanlage dadurch, dass in einem ersten Schritt derjenige Heizkörper (per Messung) ermittelt wird, der bei seinem Nenn-Volumenstrom (also der Volumenstrom, auf den der Heizkörper ausgelegt ist) und im Alleinbetrieb die größte Druckdifferenz zwischen Vor- und Rücklaufanschluss verursacht, dass in einem zweiten Schritt alle bis auf den ermittelten Heizkörper vom Heizkreislauf abgekoppelt werden und für den ermittelten Heizkörper bei Nenn-Volumenstrom die sich zwischen Vor- und Rücklaufanschluss ergebende Druckdifferenz ermittelt wird, und dass in weiteren Schritten ein Heizkörper nach dem anderen jeweils im Alleinbetrieb und jeweils bei Nenn-Volumenstrom durch Einstellung einer am Heizkörper vorgesehenen Drosseleinrichtung derart justiert wird, dass sich jeweils die im zweiten Schritt ermittelte Druckdifferenz zwischen dem Vor- und Rücklaufanschluss einstellt. - Wie ohne Weiteres ersichtlich, sind erfindungsgemäß somit für den hydraulischen Abgleich der Heizungsanlage am Heizkreislauf bzw. an den Heizkörpern keinerlei zusätzliche Installationen oder dergleichen erforderlich, d. h. der gesamte Abgleich kann mit Hilfe der erfindungsgemäß am Heizgerät vorgesehenen Mess- und Anzeigevorrichtungen erfolgen, was insbesondere, wie eingangs erwähnt, bei Altanlagen von besonderem Vorteil ist, da bei diesen Informationen zum Beispiel über die Druckverluste der einzelnen Stänge des Heizkreislaufes in der Regel nicht vorliegen bzw. auch nicht ohne Weiteres ermittelbar sind.This balancing takes place with the heating system according to the invention in that in a first step, that radiator is determined (by measurement), which at its nominal volume flow (ie the volume flow to which the radiator is designed) and in single mode the largest pressure difference between and return connection causes that are decoupled in a second step, all except for the determined radiator from the heating circuit and for the determined radiator at nominal flow rate which is determined between flow and return port pressure difference is determined, and that in further steps, one radiator after the other each alone and at nominal flow rate by adjusting a throttle body provided on the throttle device is adjusted such that each set the determined in the second step pressure difference between the flow and return port. - As readily apparent, according to the invention thus for the hydraulic balancing of the heating system on the heating circuit or on the radiators no additional installations or the like are required, d. H. the entire adjustment can take place with the help of the invention provided on the heater measuring and display devices, which in particular, as mentioned above, is particularly advantageous for old systems, as in this information, for example, about the pressure losses of the individual rods of the heating circuit usually not present or not readily ascertainable.
Nach der Erfindung ist weiterhin verfahrensmäßig vorgesehen, dass beim hydraulischen Abgleich mit einem Mittel zur Erfassung des Volumenstroms der erforderliche Nenn-Volumenstrom des Heizkreislaufs ermittelt wird, und dass nach Durchführung des hydraulischen Abgleichs die Leistung der Heizkreispumpe so eingestellt wird, dass der ermittelte Nenn-Volumenstrom genau erreicht wird.According to the invention, it is further procedurally provided that the required nominal volume flow of the heating circuit is determined during hydraulic balancing with a means for detecting the volume flow, and that after carrying out the hydraulic balancing, the power of the heating circuit pump is adjusted such that the determined nominal volume flow exactly reached.
Mit anderen Worten ausgedrückt, wird die beim hydraulischen Abgleich gewonnene Information über den erforderlichen Volumenstrom erfindungsgemäß zur Einstellung der optimalen Pumpenleistung genutzt. Dabei können die Mittel zur Erfassung des Volumenstrom sowohl am Heizgerät selbst (siehe hierzu auch Patentanspruch 1), aber auch an den einzelnen Heizkörpern angeordnet sein (siehe hierzu Patentanspruch 3). Wesentlich ist, dass die Heizkreispumpe erfindungsgemäß genau die Förderleistung erbringt, die tatsächlich erforderlich ist, sprich, die Einstellung der Pumpenleistung erfolgt erfindungsgemäß nicht mehr schlicht durch Schätzung.In other words, the information obtained about the required volume flow during hydraulic balancing is used according to the invention for setting the optimum pump performance. In this case, the means for detecting the volume flow can be arranged both on the heater itself (see also claim 1), but also on the individual radiators (see claim 3). It is essential that the heating circuit pump according to the invention provides exactly the capacity that is actually required, that is, the adjustment of the pump power according to the invention is no longer simply by estimation.
Andere vorteilhafte Weiterbildungen der erfindungsgemäßen Heizungsanlage ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the heating system according to the invention will become apparent from the dependent claims.
Die erfindungsgemäße Heizungsanlage einschließlich ihrer vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert.The heating system according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

Wesentlich für die erfindungsgemäße Heizungsanlage ist nun, dass das Heizgerät 1 zur Durchführung eines hydraulischen Abgleichs der Heizungsanlage mit Mitteln 7 zur Erfassung und auch Anzeige des vom Heizgerät bereitgestellten Heizkreislaufmedium-Volumenstroms (vorzugsweise ein Volumenstrommesser oder eine Einrichtung zur Berechnung des Volumenstroms auf Grundlage anderer Messwerte) und mit Mittelr. 8 zur Erfassung und auch Anzeige der Druckdifferenz (vorzugsweise ein Differenzdruckmesser oder eine Einrichtung zur Berechnung der Druckdifferenz auf Grundlage anderer Messwerte) zwischen dem Vor- und dem Rücklaufanschluss 3, 4 versehen ist.It is essential for the heating system according to the invention that the heater 1 for carrying out a hydraulic adjustment of the heating system with means 7 for detecting and also displaying the provided by the heater Heizkreislaufmedium volume flow (preferably a volumetric flow meter or means for calculating the volume flow based on other measurements) and with Mittelr. 8 for detecting and also displaying the pressure difference (preferably a differential pressure gauge or a device for calculating the pressure difference based on other measured values) between the supply and the
Mit Hilfe dieser beiden Ermittlungseinrichtungen wird der hydraulische Abgleich der Heizungsanlage dann derart durchgeführt, dass in einem ersten Schritt derjenige Heizkörper 5 ermittelt wird, der bei seinem Nenn-Volumenstrom und im Alleinbetrieb die größte Druckdifferenz zwischen Vor- und Rücklaufanschluss 3, 4 verursacht (also Auswahl des Heizkörpers), dass in einem zweiten Schritt alle bis auf den ermittelten Heizkörper 5 vom Heizkreislauf 6 abgekoppelt werden (also wiederum oder weiterhin Alleinbetrieb) und für den ermittelten Heizkörper 5 bei Nenn-Volumenstrom die sich zwischen Vor- und Rücklaufanschluss 3, 4 ergebende Druckdifferenz ermittelt wird (also Messung der Druckdifferenz für den ausgewählten Heizkörper), und dass in weiteren schritten ein Heizkörper 5 nach dem anderen jeweils im Alleinbetrieb und jeweils bei Nenn-Volumenstrom durch Einstellung einer am Heizkörper 5 vorgesehenen Drosseleinrichtung 9 derart justiert wird, dass sich jeweils die im zweiten Schritt ermittelte Druckdifferenz zwischen dem Vor- und Rücklaufanschluss 3, 4 einstellt.With the help of these two detection devices of the hydraulic balancing of the heating system is then carried out such that in a first step, the radiator 5 is determined which causes the largest pressure difference between the supply and

Die Kombination all dieser Merkmale führt im Ergebnis zu einer Heizunganlage, die sich bei entsprechender Auslegung der Software der Heizungsregelung 2 ohne jeden weiteren Eingriff von aussen vollständig selbst hydraulisch abgleichen kann, und dies wahlweise bei der Installation der Anlage, aber auch zu jedem anderen, späteren Zeitpunkt. Hierdurch ist es sehr einfach, die Heizunganlage zu verändern (zum Beispiel durch Ergänzung eines Heizkörpers oder Austausch des Heizgeräts); darüber hinaus kann die Anlage aber auch selbsttätig auf Veränderungen wie Verstopfungen oder dergleichen reagieren, und zwar bei Bedarf auch mit einer entsprechenden (Warn-) Signalausgabe.The combination of all these features leads to the result of a heating system that can match itself with appropriate design of the software of the heating control 2 without any further intervention from the outside completely hydraulically, and this either during installation of the system, but also to any other, later Time. This makes it very easy to change the heating system (for example, by adding a radiator or replacement of the heater); In addition, the system can also react automatically to changes such as blockages or the like, and if necessary also with a corresponding (warning) signal output.
Schließlich ist zur weiteren Abstimmung der Gesamtanlage vorgesehen, dass während des hydraulischen Abgleichs mit einem Mittel 7, 10 zur Erfassung des Volumenstroms der erforderliche Nenn-Volumenstrom des Heizkreislaufs ermittelt wird und dass in einem zweiten Schritt die Leistung der Heizkreispumpe 13 solange erhöht wird, bis der ermittelte Nenn-Volumenstrom erreicht ist. Im Unterschied zum vorbekannten Stand der Technik wird die Pumpenleistung somit nicht mehr nur noch geschätzt, sondern exakt auf die tatsächlich Anforderungen eingestellt, was regelmäßig und vorteilhaft zu einem geringeren Stromverbrauch der Anlage führt.Finally, it is provided for further tuning of the overall system that during the hydraulic balancing with a
