Description

Verfahren und Einrichtung zum Aufheizen von 1-leißwasserspeicheranlagen mittels Elektrodendurchlauferhitzer Bei großen Heißwasserspeicheranlagen, wie sie insbesondere für Gebäudebeheizungen verwendet werden, wird häufig eine größere Anzahl von Speicherkesseln durch einen oder mehrere elektrische Durchlauferhitzer aufgeheizt, indem das kalte Wasser der Speicherkessel aus deren unterem Teil abgesaugt und durch die Durchlauferhitzer mittels Umwälzpumpen hindurchgedrückt wird, so daß es mit erhöhter Temperatur wieder in den oberen Teil des Speichers gelangt. Da der elektrische Widerstand des Wassers mit steigender Temperatur abnimmt, ändert sich die Leistungsaufnahme der Durchlauferhitzer während der Aufheizung der Speicheranlage. Um eine bestimmte mittlere Leistungsaufnahme zu erzielen, muß man infolgedessen die Durchlauferhitzeranlage für die maximale Leistungsaufnahme einrichten, ;also für einen Leistungswert,. der den Mittehvert der Leistungsaufnahme in der Regel bedeutend übersteigt. Dies führt jedoch zu sehr großen Abmessungen der Durchlauferhitzer.Method and device for heating 1-circuit water storage systems by means of an electrode water heater For large hot water storage systems like them used in particular for heating buildings, a larger number is often used heated by storage boilers by one or more electrical instantaneous water heaters, by sucking the cold water of the storage boiler from its lower part and through the water heater is pushed through by means of circulation pumps, so that it is with increased temperature returns to the upper part of the storage tank. Since the electric The resistance of the water decreases with increasing temperature, the power consumption changes the water heater during the heating of the storage system. To a certain To achieve medium power consumption, you have to use the water heater system set up for the maximum power consumption, i.e. for a power value. the usually significantly exceeds the average power consumption. this leads to however, too large dimensions of the water heater.

Die Erfindung bezweckt, diesen Nachteil zu beseitigen und eine erhebliche Verkleinerung und Verbilligung der Durchlaiiferhitzeranlage sowie eine Vergleichmäßigimg der Leistiuigsaufnalune herbeizuführen. Dies wird gemäß der Erfindung dadurch erreicht, daß nur ein Teil des zu erhitzenden Wassers als Kaltwasser dem untersten Speicherteil und der aridere Teil einer höher gelegenen Stelle des Speichers, an der noch heißes Wasser verfügbar ist, also einem Teil, der die Aufladetemperatur der Speicheranlage besitzt, entnommen wird. Zur Erzielung der richtigen Eintrittstemperatur an den Durchlauferhitzern muß man das kalte Wasser des untersten Speicherteiles mit dem heißen Wasser des obersten Speicherteiles m einem bestimmten Verhältnis mischen. Hierzu wird zweckmäßig in der das Mischwasser führenden Leitung ein selbsttätig wirkendes Ventil vorgesehen, welches durch ein an der Eintrittsstelle des Gemisches in die Durchlauferhitzer angeordnetes temperaturempfindliches Organ in Abhängigkeit von der Eintrittstemperatur des Gemisches gesteuert wird.The invention aims to eliminate this disadvantage and a considerable one Downsizing and cheaper of the continuous heater system as well as a comparative to bring about the efficiency. According to the invention, this is achieved by that only part of the water to be heated is used as cold water in the lowermost storage part and the arid part of a higher part of the tank, where the still hot Water is available, so a part that the charging temperature of the storage system owns, is taken. To achieve the correct inlet temperature to the The cold water of the lowest part of the storage tank must be mixed with the flow heater Mix the hot water of the uppermost part of the storage tank in a certain ratio. For this purpose, it is expedient to have an automatic function in the line carrying the mixed water acting valve provided, which by a at the entry point of the mixture temperature-sensitive organ arranged in the water heater as a function of is controlled by the inlet temperature of the mixture.

Damit man zu Beginn der Aufheizung genügend heißes Wasser zur Verfügung hat, empfiehlt es sich, die Speicheranlage reichlich zu bemessen, so daß nach Entnahme der zum Mischen benötigten Heißwassermenge stets noch ein kleiner Rest heißen. Wassers übrigbleibt.So that there is enough hot water available at the beginning of the heating process it is advisable to adequately dimension the storage system so that after removal the The amount of hot water required for mixing is always a small one The rest are called. Water remains.

Um eine gleichmäßige- Heißwass.eneinführung bzw. -abführung herbeizuführen, sind die in dem oberen Teil des Speicherkessels sich erstreckenden Leitungen mit Durchbrechungen versehen.In order to bring about an even hot water inlet and outlet, are the lines extending in the upper part of the storage tank Provide breakthroughs.
