Die in der Wärmespeiehereinrichtung l6 am Wärmeaustausch beteiligten Medien sind voneinander jeweils durch eine Wärmedurchgangs= wandung getrennt.Those involved in the heat exchange in the heat storage device l6 Media are separated from each other by a heat transfer wall.
Die Aggregateinheit 18 zur Umsetzung des Dampfdruckes des Arbeits= mittels in elektrischen Strom besteht aus einer Dampfturbine 28, einem über eine Welle 20 mit der Turbine 28 kraftschlüssig verbundenen Strom= generator 32, einem Dampfkondensator 34 und einer Kondensatpumpe 36.The aggregate unit 18 for the implementation of the steam pressure of the work = by means of in electrical current consists of a steam turbine 28, a current connected in a force-locking manner to the turbine 28 via a shaft 20 = generator 32, a steam condenser 34 and a condensate pump 36.
Die Erfindung ist selbstverständlich nicht auf das Verfahren zur Energiewandlung mittels Verdampfung eines Arbeitsmittels begrenzt, sondern ist vielmehr für verschiedene Verfahren zur Energiewandlung allgemein anwendbar.The invention is of course not limited to the method for energy conversion by means of evaporation of a working medium, Rather, it is generally applicable to various methods of energy conversion.
Die Strömungsverbindung zwischen Absorber 14, Wärmespeioherein= richtung l6 und der Aggregateinheit l8 ist wie folgt:The flow connection between absorber 14, heat storage unit = direction l6 and the aggregate unit l8 is as follows:

The flow circuit 48 of the working = - by means of 20 closes an exhaust line 50, which the turbine 28 with the capacitor 34 connects.
Nach der Erläuterung des Aufbaus der Wärmekraftanlage 10 sei nun der Betriebsablauf der Anlage beschrieben.After explaining the structure of the thermal power plant 10, let us now the operational sequence of the plant is described.
Das im Absorber 14 erwärmte Wärmetransportmittel 24 fördert die Pumpe 40 in Richtung des Pfeiles a zur Wärmespeichereinrichtung l6. In der Wärmespeichereinriehtung l6 erfolgt ein Wärmeaustausch zwischen dem Wärmetransportmittel 24 und dem Wärmespeichermittel 26, das hierbei Schmelzwärme aufnimmt. Nach erfolgtem Wärmeaustausch strömt das WKrme= transportmittel 24 in Richtung des Pfeiles b zurück zum Absorber 14, wo es erneut Wärmeenergie aufnimmt.The heat transport medium 24 heated in the absorber 14 conveys the pump 40 in the direction of the arrow a to the heat storage device l6. In the heat storage device l6 there is an exchange of heat between the heat transport means 24 and the heat storage means 26, which in this case Absorbs heat of fusion. After the heat exchange has taken place, the WKrme = flows transport means 24 in the direction of arrow b back to the absorber 14, where it again absorbs thermal energy.
Die Umwälzung des Wärmetransportmittels 24 ist auf die Tageszeit begrenzt.The circulation of the heat transport medium 24 is due to the time of day limited.
Beim Anfahren der Wärmekraftanlage 10 erfolgt zuerst eine Aufheizung des Wärmespeichermittels 26 in der Wärmespeiehereinrichtung 16, bis dieses vollständig geschmolzen ist. Sodann erfolgt sowohl bei Tagesbetrieb, als auch bei Nachtbetrieb eine Durchströmung der Wärmespeichereinrich= tung 16 mit einer konstanten Durchsatzmenge des Arbeitsmittels 20. Das Fördervolumen der Kondensat-bzw. Arbeitsmittelpumpe ]56, das in Richtung des Pfeiles c strömt, ist hierbei derart bemessen, so daß die Temperatur des Wärmespeichermittels 26 in der Wärmespeichereinriohtung l6 einen konstanten Durchschnittswert aufweist.When the thermal power plant 10 is started up, it is first heated of the heat storage means 26 in the heat storage device 16 until it is completely melted. Then, both during daytime operation, as well as during night operation a flow through the heat storage device 16 with a constant throughput of the working medium 20. The Delivery volume of the condensate or. Working fluid pump] 56, that towards of the arrow c flows, is here dimensioned such that the temperature of the heat storage means 26 in the heat storage device l6 a has a constant average value.
Auf diese Weise wird dem Wärmespeichermittel 26 bei Tag eine kleinere Wärmemenge entzogen, als das Wärmespeichermittel mittels des Wärmetransportmittels 24 zugeführt erhält.In this way, a smaller amount of heat is withdrawn from the heat storage means 26 during the day than the heat storage means by means of the Heat transport medium 24 is supplied.
Bei Tag steigt somit die Temperatur des Wärmespeichermittels 26 um wenige Grad über dessen Schmelzpunkt an, während die Temperatur des Wärmespeichermittels 26 in der Speichereinrichtung l6 bei Nacht durch die Beheizung des Arbeitsmittels 20 wieder sinkt.During the day, the temperature of the heat storage means 26 rises a few degrees above its melting point, while the temperature of the Heat storage means 26 in the storage device l6 decreases again at night due to the heating of the working medium 20.
Das Speichervolumen der Wärmespeichereinriohtung l6 ist hierbei vorteilhaft derart bemessen, so daß die Temperatur des Wärmespeieher= mittels 26 nur wenige Grade um dessen Schmelzpunkt herum schwankt.The storage volume of the heat storage unit is l6 here advantageously dimensioned so that the temperature of the heat accumulator = by means of 26 fluctuates only a few degrees around its melting point.
