Description
Die Erfindung geht aus von einer Warmwasserversorgungsanlage nach der Gattung des Hauptanspruchs. Bei bekannten Anlagen dieser Gattung (DE 34 31 555 A1), deren Heizgerät einen über einen Heizwasserkreis gespeisten Sekundärwärmeübertrager für Brauchwassererwärmung hat, führt der Strömungskreis für Zirkulationswasser durch einen Speicher, der ebenfalls vom Heizwasserkreis gespeist und zumindest auf Erhaltungstemperatur des Zirkulationswassers gehalten ist. Dadurch kann zwar die Einschalthäufigkeit des Heizgerätes in Zeiten geringen Heizungs- und Brauchwasserwärmebedarfs verringert werden. Die Erwärmung eines Speichers und die dafür notwendigen Installationsmittel und -arbeiten erhöhen jedoch den Fertigungsaufwand und die Kosten für das Heizgerät.The invention relates to a hot water supply system according to the preamble of the main claim. In known systems of this type (DE 34 31 555 A1), the heater of which has a secondary heat exchanger for hot water heating which is fed via a heating water circuit, the flow circuit for the circulation water leads through a storage device which is also fed by the heating water circuit and is at least kept at the maintenance temperature of the circulation water. As a result, the frequency at which the heater is switched on can be reduced in times of low heating and hot water heating requirements. However, the heating of a storage tank and the installation means and work required for this increase the production outlay and the costs for the heater.
Die erfindungsgemäße Anordnung mit den Merkmalen des Hauptanspruchs hat den Vorteil, daß das Heizgerät im reinen Zirkulationsbetrieb nur eingeschaltet wird, wenn die Temperatur des Wärmeübertragers auf die Erhaltungstemperatur des Zirkulationswassers abgesunken ist. Dadurch wird auch ohne Erwärmung und Installation eines Speichers die Einschalthäufigkeit des Heizgerätes in sonst wärmebedarfsarmen Zeiten verringert und auf den tatsächlichen Bedarf zur Erhaltung der Zirkulationswassertemperatur abgestellt.The arrangement according to the invention with the features of the main claim has the advantage that the heater is only switched on in pure circulation mode when the temperature of the heat exchanger has dropped to the maintenance temperature of the circulation water. This will also Without heating and installing a storage tank, the frequency at which the heater is switched on is reduced in times that are otherwise low in heat requirements and based on the actual need to maintain the circulating water temperature.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Ausgestaltungen der Anordnung nach dem Hauptanspruch möglich.The measures listed in the subclaims allow advantageous configurations of the arrangement according to the main claim.
Zum Steuern der Wärmequelle bei reinem Zirkulationsbetrieb kann vorteilhaft ein die Heiztemperatur des Wärmeübertragers erfassender Temperatursensor vorgesehen sein. Zusätzlich dazu kann zwischen dem Wärmeübertrager und dem Warmwasseranschluß des Heizgerätes ein Sensor zur Erkennung der Warmwasser- bzw. Zapfwassertemperatur vorgesehen sein.A temperature sensor that detects the heating temperature of the heat exchanger can advantageously be provided to control the heat source in pure circulation mode. In addition, a sensor for detecting the hot water or tap water temperature can be provided between the heat exchanger and the hot water connection of the heater.
Die Zirkulationswassermenge kann einfach und betriebssicher durch die Anordnung eines Wassermengenbegrenzers in der Zirkulationsleitung auf einen unterhalb der Einschaltwassermenge liegenden Wert begrenzt sein. Der unterschiedliche Wasserstrom zwischen der Zirkulations- und der normalen Zapfwassermenge kann vorteilhaft durch einen zwischen dem Kaltwasseranschluß und dem Wärmeübertrager angeordneten Wassermengensensor ermittelt werden.The amount of circulation water can be limited simply and reliably by arranging a water flow limiter in the circulation line to a value below the amount of water that is switched on. The different water flow between the circulation and the normal tap water quantity can advantageously be determined by a water quantity sensor arranged between the cold water connection and the heat exchanger.
Bei Anlagen mit einem Heizgerät, dessen Wärmequelle auch einen Wärmeübertrager in einem Heizungswassernetz speist (Umlaufwasserheizer), kann die Zirkulationswassererwärmung ohne Vorrat parallel bei der Heizungswassererwärmung erfolgen, so daß die Wärmezufuhr in das Heizungswassernetz nicht unterbrochen oder verzögert wird.In systems with a heater, the heat source of which also feeds a heat exchanger in a heating water network (circulating water heater), the circulation water can be heated without a supply in parallel with the heating water so that the heat supply to the heating water network is not interrupted or delayed.
Die parallele Erwärmung von Heizungswasser und Zirkulationswasser läßt sich einfach realisieren, wenn beide Wärmeübertrager zu einer Baueinheit vereinigt sind.The parallel heating of heating water and circulation water can be easily achieved if both heat exchangers are combined into one unit.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der folgenden Beschreibung näher erläutert. Die einzige Figur zeigt ein Prinzipschaubild einer Anlage für Heizungswassererwärmung und Brauchwasserbereitung.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. The only figure shows a basic diagram of a system for heating water and domestic hot water.
Die dargestellte Anlage hat ein Heizgerät 10 mit einem Gasbrenner 12, der einen kombinierten Wärmeübertrager 14 für Heizungswasser und Brauchwasser beheizt. Der als Lamellenblock ausgebildete Wärmeübertrager 14 ist durchsetzt von einer Heizungswasser führenden Leitung, deren Vorlaufstrang 16 mit einem Anschluß 18 für ein durch das Symbol 20 dargestelltes Heizungsnetz verbunden ist. Dessen anderes Ende ist über einen Anschluß 22 am Heizgerät 10 mit einem Rücklaufstrang 24 verbunden, der über eine Umwälzpumpe 25 zum Heizungswassereingang des Wärmeübertragers 14 führt.The system shown has a heater 10 with a gas burner 12, which heats a combined heat exchanger 14 for heating water and process water. The heat exchanger 14 designed as a lamella block is penetrated by a line carrying heating water, the flow line 16 of which is connected to a connection 18 for a heating network represented by the symbol 20. Its other end is connected via a connection 22 on the heater 10 to a return line 24, which leads via a circulating pump 25 to the heating water inlet of the heat exchanger 14.
Der Lamellenblock des Wärmeübertragers 14 ist auch von Brauchwasser führenden Rohren durchsetzt, die über einen Kaltwasserstrang 26 mit einem Kaltwasseranschluß 28 und über einen Warmwasserstrang 30 mit einem Warmwasseranschluß 32 verbunden sind. An den Warmwasseranschluß 32 ist eine Leitung 34 angeschlossen, die zu Zapfstellen 36 führt. In dem Kaltwasserstrang 26 ist ein Wassermengenbegrenzer 38 eingebaut, der auf den vorgegebenen Maximalwert der pro Zeiteinheit durchfließenden Zapfwassermenge eingestellt ist. Am Warmwasserstrang 30 ist ein Temperatursensor 40 vorgesehen, der mit der nicht dargestellten Steuereinrichtung des Gerätes verbunden ist, welche u. a. die Temperatur des durchlaufenden Zapfwassers steuert bzw. regelt.The finned block of the heat exchanger 14 is also penetrated by pipes carrying process water which are connected via a cold water line 26 to a cold water connection 28 and via a hot water line 30 to a hot water connection 32. A line 34 is connected to the hot water connection 32, which leads to taps 36. A water quantity limiter 38 is installed in the cold water line 26 and is set to the predetermined maximum value of the tap water quantity flowing through per unit time. A temperature sensor 40 is on the hot water line 30 provided, which is connected to the control device of the device, not shown, which controls or regulates, among other things, the temperature of the tap water flowing through.
Die dargestellte Anlage hat ferner einen Strömungskreis für Zirkulationswasser, der über eine Zirkulationsleitung 42 führt. Diese hat einen inneren Leitungsstrang 44, der an einem Anschluß 46 vom Kaltwasserstrang 26 abzweigt und über einen Wassermengenbegrenzer 48 zu einem Zirkulationsanschluß 50 des Gerätes führt. Von dort geht die Zirkulationsleitung 42 über einen Rückflußverhinderer 52 und eine Zirkulationspumpe 54 zu der Zapfstelle 36 weiter, wo sie an die in das Zapfwasser führende Leitung 34 entsprechend verzweigt angeschlossen ist.The system shown also has a flow circuit for circulation water, which leads via a circulation line 42. This has an inner line 44 which branches off from the cold water line 26 at a connection 46 and leads via a water quantity limiter 48 to a circulation connection 50 of the device. From there, the circulation line 42 continues via a backflow preventer 52 and a circulation pump 54 to the tap 36, where it is connected correspondingly branched to the line 34 leading into the tap water.
Der Strömungskreis für das Zirkulationswasser schließt sich über jenen Abschnitt der Zapfwasserleitung, der vom Anschluß 46 zum Warmwasseranschluß 32 und von dort weiter zu den Zapfstellen 36 führt. In diesen Abschnitt ist zwischen dem Wassermengenbegrenzer 38 und dem Wärmeübertrager 14 eine Turbine als Wassermengensensor (56) eingebaut. Der Wassermengenbegrenzer 48 ist so eingestellt, daß die Zirkulationswassermenge kleiner als die Einschaltwassermenge ist, bei welcher das Heizgerät 10 bei der für die Erwärmung des Zapfwassers vorgesehenen Leistung in Betrieb geht. Alternativ zum Wassermengenbegrenzer 48 kann auch ein Wassermengensensor eingesetzt werden, mit dessen Hilfe die Zirkulationswassermenge gesteuert bzw. begrenzt werden kann. Aufgrund gesetzlicher Bestimmungen ist es z.B. vorgeschrieben, daß das Zirkulationswasser zur Beseitigung der Legionellengefahr eine Mindesttemperatur aufweist. Mit Hilfe des Wassermengensensors und der Zirkulationspumpe 54 kann entsprechend dieser Vorgabe die Zirkulationswassermenge erfaßt und eingestellt werden. Die Zirkulationspumpe 54 kann weiterhin durch bekannte Mittel, wie z. B. durch ein Zeitschaltwerk, gesteuert sein.The flow circuit for the circulation water closes via that section of the tap water line which leads from the connection 46 to the hot water connection 32 and from there to the tap 36. In this section, a turbine is installed as a water quantity sensor (56) between the water quantity limiter 38 and the heat exchanger 14. The water flow limiter 48 is set so that the circulation water quantity is smaller than the switch-on water quantity at which the heater 10 starts operating at the power intended for heating the tap water. As an alternative to the water quantity limiter 48, a water quantity sensor can also be used, with the aid of which the circulation water quantity can be controlled or limited. Due to legal regulations, it is mandatory, for example, that the circulation water has a minimum temperature to eliminate the risk of legionella. With the help of the water quantity sensor and the circulation pump 54, the circulation water quantity can be detected and adjusted in accordance with this specification. The circulation pump 54 can continue by known means such. B. controlled by a timer.
Der Wassermengensensor 56 erkennt den unterschiedlichen Wasserstrom zwischen dem Zirkulationsbetrieb und der normalen Zapfwasserentnahme. Wenn die Temperatur am Wärmeübertrager 14 unter einem der Zirkulationstemperatur zugeordneten Wert abgefallen ist, wird der Gasbrenner 12 mit der für die Erwärmung des Zirkulationswassers auf einen vorgegebenen Sollwert bzw. auf die Erhaltungstemperatur erforderlichen Leistung in Betrieb gesetzt. Zum Erfassen der Temperatur am Wärmeübertrager 14 kann der entsprechend ausgebildete Temperatursensor 40 dienen oder ein zusätzlicher Temperatursensor unmittelbar am Wärmeübertrager 14 vorgesehen sein. Wenn gleichzeitig eine Wärmeanforderung aus dem Heizungsnetz vorliegt, kann die Zirkulationswassererwärmung im Vorrang erfolgen. Wenn jedoch bei Wärmeanforderung aus dem Heizungsnetz die Temperatur des Wärmeübertragers über dem Sollwert liegt, kann ein Parallelbetrieb von Zirkulationswassererwärmung und Heizungswassererwärmung vorgesehen werden.The water quantity sensor 56 detects the different water flow between the circulation mode and the normal tap water withdrawal. If the temperature at the heat exchanger 14 has dropped below a value assigned to the circulation temperature, the gas burner 12 is put into operation with the power required for heating the circulation water to a predetermined setpoint value or to the maintenance temperature. The appropriately designed temperature sensor 40 can be used to detect the temperature at the heat exchanger 14 or an additional temperature sensor can be provided directly at the heat exchanger 14. If there is a heating request from the heating network at the same time, DHW heating can take priority. However, if the temperature of the heat exchanger is above the setpoint when there is a demand for heat from the heating network, parallel operation of DHW heating and heating water heating can be provided.
