Abstract

A hot water heating system operating on the storage principle for use in district heating layouts, having a vessel with a domestic water inlet situated at vessel base and an upper domestic water outlet. A series of spiral finned heat exchange units are fitted around the vessel base and linked to the district heating system. The heat exchanger units (12) are supplied by the return flow rate. A thermostatic control is integrated with the entire district heating layout.

Description

Nach dem Speicherprinzip arbeitender Warmwasser- Hot water tanks working according to the storage principle

bereiter für Fernheizanlagen Die Erfindung bezieht sich auf einen nach dem Speicherprinzip arbeitenden Warmwasserbereiter für Fernheizanlagen, der aus einem Behälter mit unterem Brauchwassereintritt und oberem Brauchwasseraustritt und einer im Inneren des Behälters angeordneten, an die Vor- und Rücklaufleitung des Fernheiznetzes angeschlossenen Wärmeaustauschfläche besteht. Ready for district heating systems The invention relates to a hot water heater for district heating systems working according to the storage principle, the from a tank with a lower domestic water inlet and an upper domestic water outlet and one arranged inside the container, to the supply and return lines the heat exchange surface connected to the district heating network.

Aus der DT-PS 2 029 895 ist ein Warmwasserbereiter bekannt geworden, welcher neben der Wärmeaustauschfläche für das Fernheizwasser noch eine zweite Wärmeaustauschfläche für das Heizungsrücklaufwasser in seinem Inneren besitzt. Dadurch soll erreicht werden, daß das noch nicht ausreichend abgekühlte Wasser des Heizungsrücklaufes weiter abgekühlt wird, bevor es zum Fernheizrücklauf gelangt. Es ist somit eine bessere Ausnutzung der im Fernheizwasser enthaltenen Wärme möglich.A water heater has become known from DT-PS 2 029 895, which, in addition to the heat exchange surface for the district heating water, has a second heat exchange surface for the heating return water in its interior. This is intended to achieve that the water of the heating return that has not yet cooled down sufficiently is further cooled before it reaches the district heating return. So it is one Better utilization of the heat contained in the district heating water is possible.

Die Ausnutzung der Wärme des Fernheizwassers soll weiter verbessert werden. Insbesondere soll die Ausbildung und Wirksamkeit des Wärmetauschers für das Heizungsrücklaufwasser noch günstiger gestaltet werden.The utilization of the heat from the district heating water is to be further improved will. In particular, the training and effectiveness of the heat exchanger for the heating return water can be made even cheaper.

Gemäß der Erfindung geschieht dieses durch einen am unteren Außenmantel des Behälters angeordneten, vom Heizungsrücklauf durchströmten Wärmetauscher.According to the invention, this is done by one on the lower outer jacket of the container, through which the heating return flows through the heat exchanger.

Der Wärmetauscher ist zweckmäßigerweise als äußerer Doppelmantel ausgebildet, so daß die gesamte untere Außenfläche des Brauchwasserbereiters für den Wärmeaustausch zur Verfügung steht. Geeignete Einrichtungen, wie Elemente zum Koppeln des inneren und äußeren Wärmetauschers, Strömungsleitbleche oder Rippen zur Vergrößerung der Wärmeaustauschfläche können seine Funktion zusätzlich verbessern.The heat exchanger is expediently designed as an outer double jacket, so that the entire lower outer surface of the Water heater is available for heat exchange. Appropriate facilities, such as elements for coupling the inner and outer heat exchangers, flow baffles or fins to increase the heat exchange surface can also improve its function.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Es zeigen Fig. 1 : das Schaltschema der Fernheizanlage und Fig. 2 : die Spezialausbildung eines Wärmetauschers im Längsschnitt.1 shows the circuit diagram of the district heating system and FIG. 2 : the special training of a heat exchanger in longitudinal section.

Der Warmwasserbereiter besteht aus einem korrosionsgeschützten Behälter 1 mit einem Kaltwasserzulauf 2 , einem Brauchwasserauslauf 3 , einem Zirkulationsanschluß 4 und einer Entleerungsleitung 5 . Eine Leiteinrichtung 6 lenkt das eintretende kalte Brauchwasser gegen den Boden des Behälters und führt zu einer besseren Wärmeübertragung.The water heater consists of a corrosion-proof container 1 with a cold water inlet 2, a domestic water outlet 3, a circulation connection 4 and a drain line 5. A guide device 6 directs the entering cold service water against the bottom of the tank and leads to better heat transfer.

Vom Fernheizvorlauf 7 führt eine Leitung zu einer Wärmeaustauschfläche 8 im Warmwasserbereiter 1 . Die Wärme zufuhr wird durch den Fühler 9 eines Thermostaten mittels eines Ventiles 10 in Abhängigkeit von der gewünschten Brauchwassertemperatur geregelt.A line leads from the district heating flow 7 to a heat exchange surface 8 in the water heater 1. The heat supply is through the sensor 9 of a thermostat by means of a valve 10 depending on the desired service water temperature regulated.

Eine weitere Leitung führt vom Fernheizvorlauf 7 durch Raum-Wärmetauscher 11 und von dort in einen Wärmetauscher 12 am unteren Außenmantel des Warmwasserbereiters 1 . Hier wird unterstützt durch Rippen 13 oder spiralenförmige Leiteinrichtungen 14 die noch vorhandene Wärme an das im unteren Bereich noch kalte Brauchwasser abgegeben.Another line leads from the district heating flow 7 through room heat exchangers 11 and from there into a heat exchanger 12 on the lower outer jacket of the water heater 1 . This is supported by ribs 13 or helical guide devices 14 the remaining heat is transferred to the domestic water, which is still cold in the lower area.

Die Wärmeaustauschfläche 8 ist durch einen Stutzen 15 mit dem äußeren Wärmetauscher 12 verbunden, so daß das heiße Fernheizwasser zweifach genutzt wird. Eine Leiteinrichtung 16 am Eingang des Wärmetauschers 12 sorgt für ein getrenntes, tangentiales Einströmen beider Wasserströme.The heat exchange surface 8 is through a nozzle 15 with the outer Heat exchanger 12 connected so that the hot district heating water is used twice. A guide device 16 at the inlet of the heat exchanger 12 ensures a separate, tangential inflow of both water flows.

Vom Wärmetauscher 12 führt eine Rücklaufleitung 17 zur Fernheizanlage.A return line 17 leads from the heat exchanger 12 to the district heating system.
