Abstract
Description
Stand der TechnikState of the art
Die vorliegende Erfindung betrifft eine Heizungsanlage zum Heizen eines Gebäudes und zur Warmwasserversorgung des Gebäudes.The present invention relates to a heating system for heating a building and for hot water supply of the building.
Eine derartige Heizungsanlage weist üblicherweise einen Warmwasserspeicher auf, in dem erwärmtes Trinkwasser für ein Warmwassernetz des Gebäudes bereit gestellt wird. Desweiteren ist ein Heizwasserspeicher vorgesehen, in dem erwärmtes Heizwasser für ein Heiznetz des Gebäudes bereit gestellt wird. Insbesondere für den Fall, dass die Heizungsanlage Solarenergie zur Beheizung des Heizwassers und des Trinkwassers nutzt, ist es üblich, den ganzen Warmwasserspeicher vollständig innerhalb des Heizwasserspeichers unterzubringen. Falls die zur Verfügung stehende Solarenergie nicht ausreicht, das Trinkwasser auf die gewünschte Temperatur aufzuheizen, kann im Warmwasserspeicher ein entsprechender Wärmeübertrager angeordnet werden, der an den Heizkreis einer herkömmlichen, mit Brennstoff arbeitenden Heizeinrichtung angeschlossen ist. Der Herstellungsaufwand für die Unterbringung dieses Wärmeübertragers im Warmwasserspeicher, der seinerseits im Heizwasserspeicher untergebracht ist, ist dabei relativ hoch.Such a heating system usually has a hot water tank in which heated drinking water for a hot water network of the building provided. A heating water tank is also provided, in the heated heating water for a Heating network of the building provided. Especially in the event that the heating system Solar energy for heating the heating water and the drinking water it is common to use the whole hot water tank completely to accommodate within the heating water tank. If the for disposal standing solar energy is not sufficient, the drinking water to the desired temperature a corresponding heat exchanger can be used in the hot water tank be arranged to the heating circuit of a conventional, heating device working with fuel is connected. The Manufacturing costs for the placement of this heat exchanger in the hot water tank, which in turn is housed in the heating water tank is relatively high.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Heizungsanlage mit den Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil, dass der Aufwand zum Einbau eines Wärmeübertragers in den außerhalb des Heizwasserspeichers angeordneten Hochtemperaturspeicher relativ gering ist. Darüber hinaus eignet sich die erfindungsgemäß vorgeschlagene Aufteilung des Warmwasserspeichers in einen Hochtemperaturspeicher und einen Niedertemperaturspeicher in besonderer Weise zur Nutzung einer Niedertemperaturheizeinrichtung, wie z.B. einer Solaranlage und einer Wärmepumpe. Denn im Niedertemperaturspeicher besitzt das Trinkwasser eine vergleichsweise niedrige Temperatur, wodurch sich für die Wärmeübertragung der Niedertemperaturheizeinrichtung vergleichsweise große Temperaturdifferenzen erzielen lassen, die den Wärmeübergang begünstigen. Die Effizienz der Niedertemperaturheizeinrichtung kann somit gesteigert werden.The heating system according to the invention with the features of the independent Has claim against it the advantage that the effort to install a heat exchanger in the outside of the Heating water storage arranged high temperature storage relatively is low. About that the division proposed according to the invention is also suitable the hot water tank into a high temperature tank and one Low temperature storage in a special way to use a low temperature heating device, such as. a solar system and a heat pump. Because in the low temperature storage the drinking water has a comparatively low temperature, which makes for the heat transfer the low-temperature heating device has comparatively large temperature differences let achieve the heat transfer favor. The efficiency of the low-temperature heating device can thus be increased become.
Außerdem erfolgt über den im Hochtemperaturspeicher angeordneten Wärmeübertrager ausschließlich eine Erwärmung des Trinkwassers und nicht wie bei einer herkömmlichen Bauweise zusätzlich des Heizwassers. Die Trägheit der Warmwasserbereitung wird somit reduziert, was zu einer Komfortsteigerung führt.In addition, the only one heat exchanger arranged in the high-temperature store warming of drinking water and not, as with a conventional construction, additionally Heating water. The indolence hot water preparation is thus reduced, which leads to an increase in comfort leads.
Zweckmäßig ist der Hochtemperaturspeicher über dem Niedertemperaturspeicher angeordnet, um Konvektionseffekte ausnutzen zu können.The high-temperature storage is above the Low temperature storage arranged to take advantage of convection effects to be able to.
Von besonderem Vorteil ist eine Ausführungsform, bei welcher der Hochtemperaturspeicher und der Niedertemperaturspeicher in separaten Behältern untergebracht sind, die über eine geeignete Verbindungsleitung miteinander kommunizieren. Durch diese Maßnahme können die beiden Behälter thermisch gegeneinander isoliert werden, wodurch die thermische Endkopplung zwischen Hochtemperaturspeicher und Niedertemperaturspeicher verbessert ist.One embodiment is particularly advantageous, in which the high temperature storage and the low temperature storage in separate containers are housed over a suitable connection line communicate with each other. By This measure can the two containers thermally be isolated from each other, creating the thermal end coupling between high temperature storage and low temperature storage improved is.
Zweckmäßig werden der Heizwasserspeicher und der Niedertemperaturspeicher mittels einer Niedertemperaturheizeinrichtung, die beispielsweise mit Solarenergie und/oder Erdwärme arbeitet, beheizt. Für den Fall, dass die Heizleistung der Niedertemperaturheizeinrichtung nicht ausreicht, kann eine Hochtemperaturheizeinrichtung vorgesehen sein, die beispielsweise mit einer Brennstoffzelle oder mit fossilen Brennstoffen, wie Erdgas oder Heizöl, arbeitet. Entsprechend einer besonders vorteilhaften Ausführungsform beheizt diese Hochtemperaturheizeinrichtung einen Hochtemperaturheizkreis, der über einen Hochtemperaturwärmeübertrager den Hochtemperaturspeicher beheizt, wobei der Hochtemperaturheizkreis das Heizwasser vom Heizwasserspeicher durch die Hochtemperaturheizeinrichtung, danach durch den Hochtemperaturwärmeübertrager und/oder durch das Heiznetz des Gebäudes und anschließend zurück in den Heizwasserspeicher leitet. Bemerkenswert ist dabei, dass das Heizwasser im Heizwasserspeicher selbst nicht auf die für das Heiznetz benötigte hohe Heiztemperatur erwärmt wird, um so die Temperatur des Heizwassers im Heizwasserspeicher relativ niedrig zu halten, was für den Wirkungsgrad der zuvor beschriebenen Niedertemperaturheizeinrichtung vorteilhaft ist.The heating water tank is useful and the low-temperature store by means of a low-temperature heating device, who works with solar energy and / or geothermal energy, heated. For the case that the heating power of the low temperature heater a high temperature heating device can be provided be, for example, with a fuel cell or with fossil Fuels, such as natural gas or heating oil. According to one particularly advantageous embodiment this high-temperature heating device heats a high-temperature heating circuit, the over a high temperature heat exchanger heated the high temperature storage, the high temperature heating circuit the heating water from the heating water tank through the high-temperature heating device, then by the high temperature heat exchanger and / or through the heating network of the building and subsequently back leads into the heating water tank. It is remarkable that the heating water in the heating water tank itself does not match that for the heating network needed high heating temperature warmed the temperature of the heating water in the heating water tank to keep relatively low, what the efficiency of the previously described low temperature heating device is advantageous.
