Description

Die vorliegende Erfindung bezieht sich auf einen von zwei Wärmequellen beheizten Fluidspeicher gemäß dem Oberbegriff des Hauptanspruchs.The present invention relates to a fluid reservoir heated by two heat sources according to the preamble of the main claim.

Es ist bekannt, einen Fluidspeicher, beispielsweise einen Brauchwasserspeicher, mittels zweier Wärmequellen zu speisen, das heißt aufzuheizen. Hierzu werden häufig Solaranlagen benutzt, die den Speicher mit einer Grundlast vorheizen, wobei die Endaufheizung durch eine elektrische Heizpatrone oder eine brennstoffbeheizte Wärmequelle vorgenommen wird. Diesen Speichern ist in der Regel ein Temperaturfühler zugeordnet, der die elektrisch beheizte Wärmequelle zu- oder abschaltet.It is known to feed, ie heat, a fluid storage device, for example a domestic water storage device, by means of two heat sources. For this purpose, solar systems are often used, which preheat the storage tank with a base load, the final heating being carried out by an electrical heating cartridge or a fuel-heated heat source. A temperature sensor is generally assigned to these stores, which switches the electrically heated heat source on or off.

Es ist weiterhin bekannt, bei rein elektrisch beheizten Brauchwasserspeichern mehrere Temperaturfühler für unterschiedliche Stellglieder der Elektrobeheizung vorzusehen, um eine Aufheizung von Teilvolumina des Speichers zu ermöglichen.It is also known in the case of purely electrically heated custom water storage to provide several temperature sensors for different actuators of the electric heating to allow heating of partial volumes of the storage.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ausgehend von einem durch unterschiedliche Wärmequellen beheizten Fluidspeicher, bei einer Zapfung nur einer geringen Brauchwassermenge lediglich das Stellglied einer Wärmequelle zum Einschalten zu bringen, während bei Zapfung einer größeren Brauchwassermenge das Stellglied der anderen Wärmequelle beaufschlagt wird.The present invention is based on the object, starting from a fluid reservoir heated by different heat sources, to only switch on the actuator of one heat source when tapping only a small amount of hot water, while when tapping a larger amount of hot water, the actuator of the other heat source is acted upon.

Die Lösung dieser Aufgabe gelingt mit den kennzeichnenden Merkmalen des Hauptanspruchs. Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche sowie der nachfolgenden Beschreibung, die ein Ausführungsbeispiel der Erfindung anhand eines Schaltschemas näher erläutert.This problem is solved with the characterizing features of the main claim. Further refinements and particularly advantageous developments of the invention are the subject of the subclaims and the following description, which explains an exemplary embodiment of the invention in more detail using a circuit diagram.

Ein Fluidspeicher 1 ist als sogenannter Doppelmantelspeicher ausgebildet, er weist einen Innenraum 2 auf, der mit aufzuheizendem Gebrauchswasser gefüllt ist und der einen Kaltwassereinlaß 3 und einen Warmwasserauslaß 4 besitzt. Der Speicher ist vorzugsweise zylinderförmig ausgebildet, Ein- und Auslaß befinden sich zentral in den Stirnseiten. Der Zylindermantel des Speichers besteht aus einer äußeren Zylinderwandung 5 und einer inneren Zylinderwandung 6, zwischen beiden Wandungen bildet sich ein Hohlraum 7, der ein Stellglied einer brennstoffbeheizten Wärmequelle 8 bildet. Die brennstoffbeheizte Wärmequelle ist hier als Ölbrenner ausgebildet und steht mit einem nicht dargestellten Wärmetauscher in Verbindung. Der Wärmetauscher ist von Wasser durchsetzt, das zu einer Vorlaufleitung 9 geführt ist, in der eine mit einem Elektromotor 10 versehe Umwälzpumpe 11 angeordnet ist, deren Auslaß mit dem Stellglied 7 verbunden ist. Eine Rücklaufleitung 12 führt das Wasser vom Stellglied zurück zum Wärmetauscher der brennstoffbeheizten Wärmequelle 8.A fluid reservoir 1 is designed as a so-called double jacket reservoir, it has an interior 2 which is filled with service water to be heated and which has a cold water inlet 3 and a hot water outlet 4. The memory is preferably cylindrical, the inlet and outlet are located centrally in the end faces. The cylinder jacket of the memory consists of an outer cylinder wall 5 and an inner cylinder wall 6, a cavity 7 is formed between the two walls, which is an actuator one fuel-heated heat source 8 forms. The fuel-heated heat source is designed here as an oil burner and is connected to a heat exchanger, not shown. The heat exchanger is penetrated by water, which is led to a flow line 9, in which a circulation pump 11 provided with an electric motor 10 is arranged, the outlet of which is connected to the actuator 7. A return line 12 leads the water from the actuator back to the heat exchanger of the fuel-heated heat source 8.

Statt eines Doppelmantelspeichers könnte auch im Innenraum 2 eine Rohrschlange vorgesehen sein, die an Vorlauf- und Rücklaufleitung 9 beziehungsweise 12 angeschlossen ist und ihre Anordnung etwa im unteren Drittel des Innenraums 2 hat, sie ist in der Zeichnung mit 13 dargestellt.Instead of a double jacket storage, a pipe coil could also be provided in the interior 2, which is connected to the supply and return lines 9 and 12 and has its arrangement approximately in the lower third of the interior 2, it is shown in the drawing with 13.

Etwa in der Mitte der Höhe des Innenraums 2 ist ein Wärmefühler 14 in Gestalt eines Thermostaten angeordnet, der innerhalb eines Schaltkastens 15 einen Schaltkontakt 16 aufweist. Der Kontakt 16 ist unterhalb einer eingestellten Temperaturschwelle geschlossen, und bei Überschreiten der Grenze wird er geöffnet. Dieser Wärmefühler 14 befindet sich auf einem höheren Niveau als das obere Ende der Rohrschlange 13, wenn sie vorhanden ist. Unterhalb der Rohrschlange 13, dem am Boden des Speichers zugeordneten Einlaß 3 zugeordnet, ist ein weiterer Wärmefühler 17, in dessen Schaltkasten 18 gleichermaßen ein Schaltkontakt 19 gleicher Funktion angeordnet ist, vorgesehen. Unmittelbar unterhalb des Wärmefühlers 17 ist ein elektrisch beheizter Widerstandsheizkörper 20 vorgesehen, der ein Stellglied einer elektrisch beheizten Wärmequelle bildet.Approximately in the middle of the height of the interior 2 is a heat sensor 14 in the form of a thermostat, which has a switch contact 16 within a switch box 15. Contact 16 is closed below a set temperature threshold and is opened when the limit is exceeded. This heat sensor 14 is at a higher level than the upper end of the coil 13, if it is present. Below the pipe coil 13, assigned to the inlet 3 assigned to the bottom of the memory, a further heat sensor 17 is provided, in the switch box 18 of which a switch contact 19 of the same function is likewise arranged. Immediately below the heat sensor 17 is an electrical Heated resistance heater 20 is provided, which forms an actuator of an electrically heated heat source.

Von einer elektrischen Spannungsquelle 21 führt eine Leitung 22, die sich verzweigt, einmal zum Kontakt 16 des Wärmefühlers 14 und zum zweiten zu einem Ruhekontakt 23 einer Relaisspule 24. Vom Ruhekontakt 23 führt eine Leitung 25 zum Kontakt 19, mit diesem in Serie liegt über eine Leitung 26 der elektrisch beheizte Heizkörper 20, der auf der anderen Seite an Masse über eine Leitung 27 liegt.A line 22, which branches out, leads from an electrical voltage source 21 to the contact 16 of the heat sensor 14 and the second to a normally closed contact 23 of a relay coil 24. From the normally closed contact 23, a line 25 leads to the contact 19, which is in series with one Line 26 of the electrically heated radiator 20, which is on the other side to ground via a line 27.

Vom Kontakt 16 führt eine Leitung 28 zum Motor 10 der Umwälzpumpe 11 und zum Magnetventil beziehungsweise Gebläse des Brenners 8. Eine weitere Leitung 29 führt zur Relaisspule 24. Relaisspule, Brenneraggregate und Pumpenmotor und Spannungsquelle liegen andererseits an Masse.A line 28 leads from the contact 16 to the motor 10 of the circulation pump 11 and to the solenoid valve or blower of the burner 8. Another line 29 leads to the relay coil 24. The relay coil, burner units and pump motor and voltage source, on the other hand, are grounded.

Der Brauchwasserspeicher beziehungsweise die elektrische Schaltung für seinen Betrieb funktioniert wie folgt:

  • Es wird davon ausgegangen, daß der Speicher im aufgeheizten Zustand ist, das heißt, beide Kontakte 16 beziehungsweise 19 der Wärmefühler 14 beziehungsweise 17 sind geöffnet, die Stellglieder beider Wärmequellen sind außer Betrieb und eine Brauchwasserzapfung findet nicht statt.
The domestic hot water tank or the electrical circuit for its operation works as follows:
  • It is assumed that the memory is in the heated state, that is, both contacts 16 and 19 of the heat sensors 14 and 17 are open, the actuators of both heat sources are out of operation and there is no tap water supply.

Die Temperaturschwellen, bei denen die Kontakte 16 beziehungsweise 19 von den Wärmefühlern 14 beziehungweise 17 geschaltet werden, sind unterschiedlich. Der Wärmefühler 17 mit dem Kontakt 19 ist einem höheren Temperaturniveau zugeordnet. Das bedeutet, daß aufgrund der Wärmeabstrahlung und der Betriebsbereitschaftsverluste zunächst der Kontakt 19 wieder schließt. Die Folge davon ist, daß das Stellglied 20 der elektrisch beheizten Wärmequelle an Betriebsspannung über die Leitung 22 und den geschlossenen Kontakt 23 gelegt ist. Der Speicherinhalt wird kurzzeitig aufgeheizt, nach Erreichen der Solltemperatur öffnet der Wärmefühler 17 den Kontakt 19 wieder, und das Stellglied 20 geht außer Betrieb. Man könnte den gleichen Vorgang auch durch ein Schließen des Kontaktes 15 über den Wärmefühler 14 erreichen, nur sind die Betriebsbereitschaftsverluste eines solchen Gebrauchswasserspeichers derart gering, daß es gegenüber der elektrischen Beheizung verlustbringend ist, die brennstoffbeheizte Wärmequelle 8 in Betrieb zu setzen. Das würde nämlich bedeuten, daß einmal der Wasserinhalt des Kessels oder Umlaufwasserheizers aufgeheizt werden muß, dessen Volumen im Wärmetauscher und in den Vor- und Rücklaufleitungen vorhanden ist. Nach der kurzzeitigen Nachheizung des Speicherinhalts würde die brennstoffbeheizte Wärmequelle wieder außer Betrieb gehen, da der Kontakt 16 vom Wärmefühler 14 geöffnet wird. Die Folge dessen wäre ein Auskühlen des Kessels und dessen Vor- und Rücklaufleitungen. Die Wärmemenge, die in diesen Kreislauf hineingesteckt werden muß, kann um ein Wesentliches größer sein als die Wärmemenge, die benötigt wird, um den Speicher auf Betriebstemperatur zu halten.The temperature thresholds at which the contacts 16 and 19 are respectively 17 and 17 from the heat sensors 14 are different. The heat sensor 17 with the contact 19 is assigned a higher temperature level. This means that due to the heat radiation and the operational readiness losses, the contact 19 closes again. The result of this is that the actuator 20 of the electrically heated heat source is connected to the operating voltage via the line 22 and the closed contact 23. The memory content is briefly heated, after reaching the target temperature, the heat sensor 17 opens the contact 19 again, and the actuator 20 goes out of operation. You could also achieve the same process by closing the contact 15 via the heat sensor 14, only the operational readiness losses of such a water heater are so small that it is lossy compared to the electrical heating to put the fuel-heated heat source 8 into operation. That would mean that the water content of the boiler or circulating water heater must be heated up, the volume of which is present in the heat exchanger and in the supply and return lines. After briefly reheating the storage contents, the fuel-heated heat source would go out of operation again since the contact 16 is opened by the heat sensor 14. The consequence of this would be cooling of the boiler and its supply and return lines. The amount of heat that has to be put into this circuit can be considerably larger than the amount of heat that is required to keep the storage tank at operating temperature.

Wird das Zapfventil im Zuge der Einlaßleitung 3 oder der Auslaßleitung 4 betätigt, also der Speicher entladen, so kann es sich um eine Kleinentladungsmenge oder um eine Großentladungsmenge handeln. In jedem Fall wird in dem unteren Teil 30 des Speicherinnenraums 2 kaltes Wasser gedrückt, worauf zunächst der Wärmefühler 17 durch Schließen des Kontakts 19 anspricht. Die Folge davon ist eine beginnende Nachheizung des Speichers über das Stellglied der elektrisch beheizten Wärmequelle. Wird das Zapfventil bald wieder zugedreht, also nur eine kleine Wassermenge entnommen, so ist die elektrische Nachheizung dann beendet, wenn der Wärmefühler 17 den Kontakt 19 wieder öffnet.If the nozzle valve is actuated in the course of the inlet line 3 or the outlet line 4, that is to say the store is discharged, it can be a small discharge quantity or a large discharge quantity. In any case, cold water is pressed in the lower part 30 of the storage interior 2, to which the heat sensor 17 first responds by closing the contact 19. The consequence of this is an initial reheating of the storage via the actuator of the electrically heated heat source. If the dispensing valve is soon closed again, that is to say only a small amount of water is removed, the electrical after-heating is ended when the heat sensor 17 opens the contact 19 again.

Wird hingegen eine große Wärmemenge entnommen, so spricht außerdem der Wärmefühler 14 an und schließt den Kontakt 15. Je größer die entnommene warme Wassermenge ist, um so schneller folgt das Ansprechen des Wärmefühlers 14 auf das Ansprechen des Wärmefühlers 17. Die Folge des Schließens des Kontakts 16 ist ein Inbetriebgehen der brennstoffbeheizten Wärmequelle und ein Öffnen des Kontakts 23, so daß das Stellglied der elektrischen Wärmequelle außer Betrieb gesetzt wird. Es hat sich nämlich gezeigt, daß bei Nachschieben einer größeren Wärmemenge in den Speicher es sinnvoll ist, diese Wärmemenge über die brennstoffbeheizte Wärmequelle zu erzeugen. Je länger die brennstoffbeheizte Wärmequelle in Betrieb sein muß, um den Entladeverlust des Speichers 1 zu decken, um so weniger fallen die Anlauf- und Abkühlungsverluste der brennstoffbeheizten Wärmequelle selbst ins Gewicht gegenüber der Wärmemenge, mit der der Speicher aufgeladen werden muß. Hierbei ist auch zu berücksichtigen, daß die mittels Brennstoff erzeugte Wärmemenge billiger zu erstellen ist als die mittels elektrischem Strom erzeugte.If, on the other hand, a large amount of heat is removed, the heat sensor 14 also responds and closes the contact 15. The greater the amount of hot water withdrawn, the faster the response of the heat sensor 14 to the response of the heat sensor 17. The consequence of the closing of the contact 16 is a start-up of the fuel-heated heat source and an opening of the contact 23 so that the actuator of the electrical heat source is deactivated. It has namely been shown that when a larger amount of heat is fed into the storage unit, it makes sense to generate this amount of heat via the fuel-heated heat source. The longer the fuel-heated heat source has to be in operation in order to cover the discharge loss of the memory 1, the less the start-up and cooling losses of the fuel-heated heat source itself are significant in relation to the heat amount with which the memory must be charged. It should also be borne in mind that the amount of heat generated by fuel is cheaper to generate than that generated by electric current.

Da während des Betriebes der brennstoffbeheizten Wärmequelle der Wärmefühler 17 wirkungslos geschaltet ist, wird die Beheizung des Speichers durch Ansprechen des Wärmefühlers 14 und Öffnen des Kontakt 16 beendet. Damit ist der Speicher wieder aufgeladen.Since the heat sensor 17 is ineffective during operation of the fuel-heated heat source, the heating of the memory is terminated by the response of the heat sensor 14 and opening of the contact 16. The memory is now recharged.
