Description

Stand der Technik:State of the art:

Mit zunehmender Verwendung alternativer Energiequellen wie Solarenergie, Wärmepumpe, Holz, und Stroh werden Heizwasserspeicher eingesetzt. Die Trinkwassererwärmung wird mit darin integrierten oder externen Speichern vorgenommen.With increasing use of alternative energy sources such as solar energy, Heat pump, wood, and straw heating water storage are used. The drinking water heating is with integrated or external memory.

4 zeigt einen üblich aufgebauten Heizwasserpufferspeicher (105) für Solarenergie, Ölheizkessel (102) und Holzheizkessel (101) mit integriertem Trinkwassererwärmer (104). Die Solarheizfläche (103) ist unter dem Trinkwassererwärmer (104) so angeordnet das zunächst eine sehr große Heizwassermenge erwärmt werden muss, bevor die Aufheizung des Trinkwassers auf die, aus hygienischen Gründen nach dem DVGW Arbeitsblatt erforderlichen Trinkwassertemperatur von 50°C für Einfamilienhäuser bzw. 60°C für Mehrfamilienhäuser erfolgen kann. Die Zirkulationsverluste der Trinkwassererwärmungsanlage werden bei dieser Bauart ausschließlich von Primärenergie gedeckt. 4 shows a commonly constructed Heizwasserpufferspeicher ( 105 ) for solar energy, oil boilers ( 102 ) and wood boiler ( 101 ) with integrated drinking water heater ( 104 ). The solar heating surface ( 103 ) is under the drinking water heater ( 104 ) arranged so that initially a very large amount of heating water must be heated before the heating of the drinking water on the, for reasons of hygiene according to the DVGW worksheet required drinking water temperature of 50 ° C for single family homes or 60 ° C for apartment buildings. The circulation losses of the drinking water heating system are covered in this design exclusively by primary energy.

In vielen praktisch ausgeführten Anlagen stellen die Betreiber solcher Systeme fest, dass die Nutzung der Solarenergie sich nicht wesentlich auf die Brennstoffkosten auswirkt.In many practically executed Systems establish the operators of such systems that use solar energy does not significantly affect fuel costs effect.

Zur Verbesserung der Systeme werden aufwendige Wärmeleitsysteme für den Wärmetransport von der Solarheizfläche über den Heizwasserteil des Pufferspeichers bis an den Trinkwassererwärmer vorgesehen. Aus hygienischen Gründen und zur Verbesserung der Heizmittelauskühlung werden zunehmend Durchflusserhitzer eingesetzt Die Konstruktion des Heizwasserpufferspeichers (201) in 5 hat wegen der starken Heizmittelauskühlung bis in die Nähe der Kaltwassertemperatur einen hohen Entladewirkungsgrad und wird besonders in Verbindung mit Holz-, Öl- und Gasheizkesseln als Pufferspeicher eingesetzt.To improve the systems elaborate heat transfer systems for the heat transfer from the solar heating over the heating water part of the buffer storage to the drinking water heater are provided. For reasons of hygiene and to improve the Heizmittelkühlung increasingly flow heaters are used The construction of the Heizwasserpufferspeichers ( 201 ) in 5 has a high discharge efficiency due to the strong Heizmittelkühlung up to the vicinity of the cold water temperature and is used particularly in connection with wood, oil and gas boilers as a buffer storage.

Die nach 5 ausgeführten Anlagen mit Heizwasserpufferspeicher (201) mit integriertem Durchflusserhitzer (202) für die Trinkwassererwärmung und externem Wärmeübertrager (203) für den Solarkreis erreichen zwar einen etwas besseren Nutzungsgrad als die Anlagen nach 4, die Kosten für die Trinkwassererwärmung mit Solarenergie sind jedoch im Vergleich zum Nutzen, der durch geringeren Trinkwasserverbrauch (nach VDI Richtlinie 6002) weiter absinkt, viel zu hoch.The after 5 executed systems with heating water buffer cylinder ( 201 ) with integrated flow heater ( 202 ) for DHW heating and external heat exchanger ( 203 ) for the solar circuit achieve a slightly better degree of utilization than the plants 4 However, the costs for DHW heating with solar energy are far too high compared to the benefits that are further reduced by lower drinking water consumption (according to VDI Guideline 6002).

Der mehrfache Wärmeübergang von der Solarheizfläche an das Heizwasser und vom Heizwasser an Trinkwasser in Verbindung mit der räumlichen Entfernung der Komponenten und den schlechten Wärmeübergangsbedingungen an den einzelnen Heizflächen ist für alle bekannten Heizwasserspeichersysteme ein großes Problem.Of the multiple heat transfer from the solar heating surface to the heating water and from the heating water to drinking water in connection with the spatial distance the components and the bad heat transfer conditions to the individual heating surfaces is for all known Heizwasserspeicher systems a big problem.

Trotz ansteigender Brennstoffkosten ist mit den bekannten Systemen für Heizung und Trinkwassererwärmung die thermische Nutzung der Solarenergie für Ein- und Zweifamilienhäuser in Deutschland ohne Fördermittel nicht wirtschaftlich möglich.In spite of increasing fuel costs is with the known systems for heating and drinking water heating the thermal utilization of solar energy for single- and two-family houses in Germany without subsidies not economically possible.

Dringend notwendige Verbesserungen sind:
Senkung der Herstellkosten,
Vereinfachung der Bauweise,
Verbesserung der Solarenergieausbeute,
Senkung des Primärenergieverbrauchs für Nachheizung des Trinkwassers und der Zirkulation Urgently necessary improvements are:
Reduction of manufacturing costs,
Simplification of the construction,
Improvement of solar energy yield,
Reduction of primary energy consumption for afterheating of drinking water and circulation

Beschreibung der erfindungsgemäßen Problemlösung durch Zusammenfassung von Durchflusserhitzer, Heizwasserführung und Integration der Solarheizfläche in einem Durchflusserhitzer.Description of the problem solution according to the invention Summary of flow heaters, heating water and Integration of the solar heating surface in a flow heater.

1 zeigt die erfindungsgemäße Ausführung und Anordnung eines Durchflusserhitzers (6) mit integrierter Solarheizfläche im Heizwasserspeicher. Die, aus einem oder mehreren Rohren kleinen Durchmessers bestehende Solarheizfläche (3) wird spiralförmig mit Steigung auf den trinkwasserführenden Wellschlauch (2) so aufgewickelt, dass für die, von der Ladepumpe (5) geförderte Heizwassermenge ein, um den Wellschlauch (2) rotierender Strömungskanal mit genau definiertem Ringspalt und verbesserten Wärmeübergangsverhältnissen vom Heizwasser an das Trinkwasser entsteht. 1 shows the embodiment and arrangement of a flow heater according to the invention ( 6 ) with integrated solar heating surface in the heating water tank. The solar heating surface consisting of one or more small diameter pipes ( 3 ) is spirally with slope on the drinking water-carrying corrugated hose ( 2 ) so wound up that for, from the charge pump ( 5 ) conveyed amount of heating water to the corrugated hose ( 2 ) creates a rotating flow channel with a precisely defined annular gap and improved heat transfer ratios of heating water to the drinking water.

Die Heizwasserladepumpe (5) fördert bei größeren Trinkwasserzapfungen Heizwasser (4) im Gegenstrom zum Trinkwasser (2) und erfindungsgemäß auch zur Solarheizfläche (3) von oben nach unten durch den Durchlauferhitzer (6). Bei stehender Ladepumpe wird über Wärmeleitung und Konvektion Trinkwasser und Heizwasser über die integrierte Solarheizfläche (3) erwärmt. Nach der Schnellaufheizung des Wärmetauschers auf die geforderte Trinkwassertemperatur durch die Solarheizfläche folgt dann der „Aufladevorgang" des Heizwasserspeichers mit geringer Fördermenge der umgekehrt laufenden Ladepumpe (5) von unten nach oben.The heating water charging pump ( 5 ) promotes heating water for larger drinking water taps ( 4 ) in countercurrent to drinking water ( 2 ) and according to the invention also to the solar heating surface ( 3 ) from top to bottom through the instantaneous water heater ( 6 ). When the charging pump is stationary, drinking water and heating water are released via heat conduction and convection via the integrated solar heating surface ( 3 ) is heated. After the rapid heating of the heat exchanger to the required drinking water temperature through the solar heating then follows the "charging" of Heizwasserspeichers with low flow of the reverse charge pump ( 5 ) from bottom to top.

Bei ausreichender Sonneneinstrahlung werden die Zirkulationsverluste der Trinkwassererwärmungsanlage nach Erreichen der geforderten Trinkwassertemperatur im Durchflusserhitzer (6) durch Solarenergie gedeckt.With sufficient solar radiation, the circulation losses of the DHW heating system after reaching the required drinking water temperature in the flow heater ( 6 ) covered by solar energy.

2 zeigt die erfindungsgemäße Vorrichtung ausgerüstet mit einem externen Plattenwärmeaustauscher (6). Zur wesentlich verbesserten Nutzung der Solarenergie wird erfindungsgemäß Trinkwasser an der Heizfläche (2), Heizwasser an der Heizfläche (4) und Wasser aus dem Solarkreis an der Heizfläche (3) in einer Einheit und im Gegenstrom zueinander geführt. Durch diese Ausführung des Plattenwärmeaustauschers erfolgt die Wärmeübertragung vom Solarkreis an das Trinkwasser und Heizwasser direkt und verzögerungsfrei. Plattenwärmeaustauscher sind preiswert und ermöglichen geringe Temperaturunterschiede von nur 5 K zwischen den Wärmeträgern. 2 shows the device according to the invention equipped with an external plate heat exchanger ( 6 ). For substantially improved use of solar energy, drinking water is applied to the heating surface ( 2 ), Heating water at the heating surface ( 4 ) and water from the solar circuit at the Heating surface ( 3 ) in one unit and in countercurrent to each other. Through this design of the plate heat exchanger, the heat transfer from the solar circuit to the drinking water and heating water takes place directly and without delay. Plate heat exchangers are inexpensive and allow small temperature differences of only 5 K between the heat carriers.

Bei außenliegendem Durchflusserhitzer (6) nach 2 ist es leicht möglich durch mit Hilfe der selbsttätig wirkenden Rückschlagklappen (10) und (11) durch Umkehr der Förderrichtung in der Ladepumpe (5) vom oberen Entladestutzen auf den unteren Beladestutzen umzuschalten. Das ist eine wichtige Voraussetzung für eine optimale Nutzung des Heizwasserspeichers.With external flow heater ( 6 ) to 2 it is easily possible by means of the self-acting check valves ( 10 ) and ( 11 ) by reversing the conveying direction in the charge pump ( 5 ) switch from the upper discharge port to the lower charging port. This is an important prerequisite for optimal use of the heating water storage tank.

Im Prinzip lässt sich auch ein integriertes Ladesystem nach 3 mit den Rückschlagklappen (10) und (11) mit den gleichen Vorteilen ausrüsten. Der Durchflusserhitzer (6) besteht aus Membranovalrohr (14) das erfindungsgemäß die wärmerleitende Verbindung der Solarheizfläche (3) mit der Trinkwasserheizfläche (2) durch die, in Folge des Trinkwasserbetriebsdruckes auftretende Verformung zustande bringt. In principle, an integrated charging system can also be used 3 with the non-return valves ( 10 ) and ( 11 ) equip with the same advantages. The flow heater ( 6 ) consists of membrane oval tube ( 14 ) according to the invention, the heat-conducting connection of the solar heating surface ( 3 ) with the drinking water heating surface ( 2 ) by the, occurring in consequence of the drinking water operating pressure deformation brings about.

Regelung:Regulation:

Die Ladepumpe (5) wird über eine geeignete Regelung abhängig von der Temperatur an den Fühlern (7) und (8) drehzahlgeregelt und fördert bei Trinkwasserzapfungen zur „Entladung" des Heizwasserspeichers in Richtung des in 1, 2 und 3 größer eingezeichneten Strömungspfeils.The charge pump ( 5 ) is controlled by a suitable control depending on the temperature at the sensors ( 7 ) and ( 8th ) speed controlled and promotes drinking water taps for "discharge" of the heating water storage in the direction of 1 . 2 and 3 larger drawn flow arrow.

Ohne Trinkwasserzapfungen, das heißt im Zirkulationsbetrieb, wird bei ausrechender Sonneneinstrahlung erfindungsgemäß zunächst bei stehender Ladepumpe (5) das Trinkwasservolumen und Heizwasservolumen im Durchflusserhitzer (6) von der Solarheizfläche (3) aufgeheizt. Bei Erreichen der geforderten Trinkwassertemperatur am Fühler (7) wird zur „Beladung" des Heizwasserspeichers mit der aufgeheizten Heizwassermenge aus dem Durchflusserhitzer (6) die Förderrichtung einer dazu geeigneten Ladepumpe (5) umgekehrt.Without drinking water taps, that is in the circulation mode, according to the invention, when the solar radiation is effective, according to the invention firstly when the charge pump is stationary ( 5 ) the drinking water volume and heating water volume in the flow heater ( 6 ) from the solar heating surface ( 3 ) heated. When reaching the required drinking water temperature at the sensor ( 7 ) is used to "load" the Heizwasserspeichers with the heated amount of heating water from the flow heater ( 6 ) the conveying direction of a suitable charge pump ( 5 ) vice versa.

Von diesem Zeitpunkt an werden auch die Zirkulationsverluste der Trinkwassererwärmung von Solarenergie gedeckt.From At this point in time, the circulation losses of drinking water heating from solar energy will become covered.
