Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Erwärmen des Wärmeträgers einer Heizung und von Brauchwasser mit einem an einen Pufferspeicher angeschlossenen, chargenweise mit Festbrennstoff befüllbaren Kessel, mit wenigstens einem über einen Vor- und einen Rücklauf mit dem Pufferspeicher verbundenen Heizkreis, mit einem im Wärmeaustausch mit dem Pufferspeicher ladbaren Warmwasserspeicher und mit einer an Temperaturfühler des Pufferspeichers und des Warmwasserspeichers sowie an einen Außentemperaturfühler angeschlossenen Steuereinrichtung für die Leistung des Kessels in Abhängigkeit vom jeweiligen Wärmebedarf.The The invention relates to a device for heating the Heat carrier one Heating and domestic water with a tank connected to a buffer Batch with solid fuel fillable boiler, with at least one over a forward and a return associated with the buffer memory heating circuit, with a heat exchange with the buffer memory loadable hot water tank and with a at temperature sensor of the buffer tank and the hot water storage tank as well as to an outside temperature sensor Control device for the power of the boiler depending on from the respective heat requirement.
Um bei chargenweise mit festem Brennstoff, insbesondere Holz, beschickbaren Kesseln zum Erwärmen des Wärmeträgers einer Heizung und von Brauchwasser die Beschickungsintervalle zu verlängern und damit den Bedienungskomfort zu erhöhen, werden Pufferspeicher mit einem entsprechend großen Volumen eingesetzt, an die sowohl die Heizkreise als auch der Ladekreis eines Warmwasserspeichers angeschlossen werden. Unter Ausnützung der Ladekapazität des Pufferspeichers kann somit der Wärmebedarf für die Heizung und das Brauchwasser über den Ausbrand der in einer Charge den Kessel zugeführten Brennstoffmenge hinaus gedeckt und damit die Chargierintervalle verlängert werden. Voraussetzung hiefür ist eine während des Abbrandes einer Brennstoffcharge ausreichende Kesselleistung, um nicht nur den jeweils anfallenden Wärmebedarf zu decken, sondern zusätzlich den Pufferspeicher zu laden. Da somit die Kesselleistung an den um die Ladeleistung des Pufferspeichers vermehrten maximalen Wärmebedarf angepaßt sein muß, ist die Kesselleistung bei einem niedrigeren Wärmebedarf zu verringern, was mit Hilfe einer Steuereinrichtung für die Verbrennungsluft des Kessels durchgeführt wird. Die Kesselleistung läßt sich allerdings nur in einem begrenzten Bereich steuern, wenn nicht der Abbrand des Feststoffes unter vorteilhaften Bedingungen gefährdet werden soll. Dies bedeutet, daß bei einem verminderten Wärmebedarf die Überschußwärme nicht genützt werden kann.Around at batch with solid fuel, especially wood, feedable Boilers for heating the heat carrier one Heating and service water to extend the feed intervals and in order to increase the ease of operation, buffer memories with a correspondingly large Volume used to which both the heating circuits and the charging circuit a hot water tank can be connected. Utilizing the loading capacity of the buffer tank can thus the heat demand for the Heating and the service water over the burnout of the amount of fuel supplied to the boiler in one batch covered and thus the charging intervals are extended. Prerequisite for this is one during the burnup of a fuel charge sufficient boiler power to not only to cover the respective heat demand, but additionally to load the buffer memory. Thus, the boiler output to the to the charging power of the buffer increased maximum heat demand customized have to be, is to reduce the boiler output at a lower heat demand, what by means of a control device for the combustion air of Boiler performed becomes. The boiler output can be but only in a limited area, if not the control Burning of the solid can be endangered under advantageous conditions should. This means that at a reduced heat requirement the excess heat is not availed can be.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zum Erwärmen des Wärmeträgers einer Heizung und von Brauchwasser der eingangs geschilderten Art so auszugestalten, daß der chargenweise dem Kessel zuzuführende Brennstoff vorteilhaft genützt werden kann, um bei einer ausreichenden Abdeckung des jeweiligen Wärmebedarfs möglichst lange Intervalle für die chargenweise Beschickung des Kessels mit Brennstoff sicherzustellen.Of the Invention is therefore the object of a device for Heat the heat carrier one To design heating and domestic water of the kind described above, that the batchwise to be supplied to the boiler Advantageously used fuel can be to provide sufficient coverage of each Heat demand as possible long intervals for to ensure the batchwise charging of the boiler with fuel.
Die Erfindung löst die gestellte Aufgabe dadurch, daß die Steuereinrichtung eine an eine Ausgabeeinheit angeschlossene Rechenstufe zur chargenweisen Vorgabe einerseits der höchstens dem Füllvolumen des Kessels entsprechenden Brennstoffmengen in Abhängigkeit von einem für einen Mittelwert der Außentemperatur vorgegebenen Wärmebedarf des Heizkreises sowie vom Ladezustand des Pufferspeichers und des Warmwasserspeichers und anderseits der Zeitintervalle zwischen den einzelnen Brennstoffchargen aufweist.The Invention solves the stated object in that the control device a to an output unit connected computing stage for batchwise Specification on the one hand the maximum the filling volume the boiler corresponding amounts of fuel depending from one for an average of the outside temperature given heat requirement of the heating circuit and the state of charge of the buffer tank and the Hot water storage and on the other hand, the time intervals between the having individual fuel charges.
Die Erfindung geht von der Erkenntnis aus, daß bei einem beispielsweise aufgrund der Außentemperatur zu erwartenden geringeren Wärmebedarf für die Heizung der Heizkessel mit einer im Vergleich zum Füllvolumen des Kessel geringeren Brennstoffmenge zu beschicken ist, um einerseits den jeweiligen Wärmebedarf abzudecken und anderseits den Pufferspeicher zu laden, und zwar unter der Voraussetzung einer vorteilhaften Nutzung des Brennstoffes. Aus diesem Grunde wird über eine Rechenstufe programmbedingt der für das jeweilige Beschickungsintervall benötigte Wärmebedarf für die Heizung aus einem gemittelten Wert der Außentemperatur gegebenenfalls unter Berücksichtigung des zeitlichen Verlaufs dieses Mittelwertes einerseits und zum Laden des Pufferspeichers und des Warmwasserspeichers anhand der diesen Speichern zugeordneten Temperaturfühler anderseits ermittelt und daraus die zur Abdeckung dieses Wärmebedarfes erforderliche Brennstoffmenge errechnet, was ja aufgrund der bekannten Daten des Kessels ohne weiteres möglich ist. Es kann daher über die Rechenstufe die Brennstoffmenge für jede Charge und das zugehörige zeitliche Intervall für die nächste Beschickung vorgegeben und angezeigt werden, was den Bedienungskomfort erheblich verbessert, zumal mit der Vorgabe der Brennstoffmenge die bei einem geringeren Wärmebedarf erforderliche Abregelung der Kesselleistung ausreichend berücksichtigt werden kann. Da während der Entladung des Pufferspeichers zur Abdeckung des Wärmebedarfes nach dem Ausbrand der jeweiligen Brennstoffcharge der Kessel abkühlt, wird bei der Bemessung der Brennstoffmenge für das nächste Beschickungsintervall vorteilhaft der Energiebedarf zum Aufheizen des Kessels berücksichtigt.The Invention is based on the recognition that in an example due to the outside temperature expected lower heat demand for the heating the boiler with a lower compared to the filling volume of the boiler Fuel quantity is to feed, on the one hand the respective heat demand cover and on the other hand to load the buffer memory, namely on the condition of advantageous use of fuel. For this reason is over a computing stage program-related for the respective feed interval needed heat demand for the Heating from an average value of the outside temperature if necessary considering the time course of this average on the one hand and for loading the buffer tank and the hot water tank based on this Save associated temperature sensor on the other hand determined and from this the amount of fuel required to cover this heat demand calculated, which is due to the known data of the boiler without further is possible. It can therefore over the computing stage the amount of fuel for each batch and the associated temporal Interval for the next Charging predetermined and displayed, which is the ease of use considerably improved, especially with the specification of the fuel quantity at a lower heat requirement required reduction of the boiler output is considered sufficiently can be. Because while the discharge of the buffer to cover the heat demand after the combustion of the respective fuel charge the boiler cools down when measuring the fuel quantity for the next charging interval Advantageously, the energy required to heat the boiler considered.
Weist die Steuereinrichtung eine Eingabeeinheit für wenigstens einen den Brennwert des Brennstoffes berücksichtigenden Parameter auf, so können gegebenenfalls unterschiedliche Brennstoffe zum Einsatz kommen, deren Brennwert bei der Berechnung der erforderlichen Brennstoffmenge über die Eingabeeinheit festgelegt wird. Es ist jedoch innerhalb einer Charge die Verwendung unterschiedlicher Brennstoffe zu vermeiden, um Fehlberechnungen auszuschließen.has the control device has an input unit for at least one of the calorific value of fuel Parameters on, so can possibly different fuels are used, their calorific value when calculating the required fuel quantity over the Input unit is determined. However, it is within a batch avoid the use of different fuels to miscalculations excluded.
Um den Pufferspeicher mit einer vorgegebenen Temperatur des Wärmeträgers unabhängig von der jeweiligen Kesselleistung laden zu können, kann die Rücklauftemperatur des Kessels in Abhängigkeit von dessen Vorlauftemperatur gesteuert werden, so daß aufgrund der in Abhängigkeit von der Kesselleistung geregelten Temperaturdifferenz zwischen Kesselvor- und -rücklauf die für die Pufferladung geforderte Vorlauftemperatur des Kessels eingehalten werden kann, gegebenenfalls bei einer geringeren Menge des dem Pufferspeicher zugeführten Wärmeträgers, weil zur Anhebung der Rücklauftemperatur der Vorlauf des Kessels mit dessen Rücklauf über ein Mischventil zu verbinden ist, das über die Steuereinrichtung entsprechend angesteuert wird.To the buffer with a predetermined temperature of the heat carrier regardless of can load the respective boiler output, the return temperature of the boiler depending on the flow temperature can be controlled so that due to the regulated depending on the boiler temperature difference between Kesselvor- and return the required for the buffer charge flow temperature of the boiler can be met, if necessary at a smaller amount of heat supplied to the buffer heat carrier, because to increase the return temperature of the flow of the boiler to connect to the return via a mixing valve, which is controlled accordingly via the control device.
