Description

Beschreibung G 91 Ol 673.8Description G 91 Ol 673.8

Die Erfindung hat den Zweck, die bei Mehrkreis-Solaranlagen auftretenden Durchströmungs- und Wärmeübertragungsprobleme effektiver als bisher nach dem Stand der Technik gehandhabt zu lösen.The purpose of the invention is to solve the flow and heat transfer problems occurring in multi-circuit solar systems more effectively than previously handled according to the state of the art.

Bei den üblichen, nach dem Stand der Technik eingesetzten Mehrkreis-Solaranlagen wird das Wärmeträgermedium nach Durchfließen der Solarkollektoren durch Zwangsumwälzung mit Hilfe von Pumpen zum Wärmetauscher transportiert.In the usual multi-circuit solar systems used according to the state of the art, the heat transfer medium is transported to the heat exchanger by forced circulation with the help of pumps after flowing through the solar collectors.

Der Kollektorkreis mit Pumpen und Wärmetauscher stellen bei einer Mehrkreisanlage den Primärkreis dar. Diese Wärmetauscher befinden sich im allgemeinen als externe oder interne Wärmetauscher räumlich beim im allgemeinen verwendeten Warmwasserspeicher, der mit den Kaltwasserzuleitungen, Warmwasserableitungen, Mischeinrichtungen usw. den Sekundärkreis bildet.The collector circuit with pumps and heat exchangers represent the primary circuit in a multi-circuit system. These heat exchangers are generally located as external or internal heat exchangers next to the generally used hot water storage tank, which forms the secondary circuit with the cold water supply lines, hot water drains, mixing devices, etc.

Diese räumliche Trennung des Wärmetauschers vom Wärmeerzeuger (Solarkollektoren) führt zu folgenden Nachteilen einer herkömmlichen Solaranlage:This spatial separation of the heat exchanger from the heat generator (solar collectors) leads to the following disadvantages of a conventional solar system:

1. Wegen der engen Querschnitte der Absorberrohre und deren erheblicher Gesamtlänge in einer Solaranlage ist der Leistungsaufwand des elektrischen Pumpensystems für die Zwangsumwälzung erheblich.1. Due to the narrow cross-sections of the absorber pipes and their considerable total length in a solar system, the power required by the electric pump system for forced circulation is considerable.

2. Die Gleichmäßigkeit der Durchströmung der Absorberrohre der Solaranlage ist besonders bei größeren Anlagen wegen der Komplexheit der Durchströmungsvorgänge nicht gewährleistet, was zu einer Verringerung des Wirkungsgrades führt.2. The uniformity of the flow through the absorber tubes of the solar system is not guaranteed, especially in larger systems, due to the complexity of the flow processes, which leads to a reduction in the efficiency.

3. Der Verrohrungsaufwand einer großen Solaranlage ist erheblich mit dem damit verbundenen Risiko von Lekkagen. 3. The piping effort for a large solar system is considerable, with the associated risk of leaks.

4. Der Durchströmungswiderstand der handelsüblichen Kompaktwärmetauscher ist relativ hoch, was zuerhöhtetf1 Pumpenleistung führt.4. The flow resistance of commercially available compact heat exchangers is relatively high, which leads to increased pump performance.

5. Der Transport des Wärmeträgermediums erfolgt im allgemeinen über lange Leitungen zum Wärmetauscher mit der erforderlichen hohen Temperaturdifferenz gegenüber dem Sekundärkreis, was einen erhöhten Isolationsaufwand für die Leitungen und erhöhte Energieverluste bedingt.5. The heat transfer medium is generally transported via long pipes to the heat exchanger with the required high temperature difference compared to the secondary circuit, which requires increased insulation for the pipes and increases energy losses.

Diese durch den Stand der Technik bedingten Mangel einer Mehrkreissolaranlage sollen durch folgende Konstruktionsmerkmale behoben werden:These deficiencies in a multi-circuit solar system, which are caused by the state of the art, are to be remedied by the following design features:

Das obere Sammelrohr (1) der Solarkollektoren wird als Primärkreis des in (1) integrierten Wärmetauschers (2) verwendet.The upper manifold (1) of the solar collectors is used as the primary circuit of the heat exchanger (2) integrated in (1).

Der Primärkreis des Solarkollektors arbeitet nach dem Thermosiphonprinzip, indem die durch die Absorberbleche (3) aufgefangene Sonnenenrgie auf das Wärmeträgermedium im Absorberrohr (4) übertragen wird, das im Vorlauf nach dem Thermosiphonprinzip die Wärme in das obere Sammelrohr transportiert, wo sie vom Wärmetauscher (2) abgenommen wird.The primary circuit of the solar collector works according to the thermosiphon principle, whereby the solar energy captured by the absorber plates (3) is transferred to the heat transfer medium in the absorber pipe (4), which transports the heat in the flow according to the thermosiphon principle into the upper collecting pipe, where it is taken up by the heat exchanger (2).

Durch die Rücklaufleitung (5) und das untere Sammelrohr (6) ist der Kreislauf geschlossen.The circuit is closed by the return line (5) and the lower collecting pipe (6).

Durch diese konstrukive Lösung werden die oben angeführten Mangel im wesentlichen behoben:This constructive solution essentially eliminates the deficiencies mentioned above:

ZuI.: Durch das Thermosiphonprinzip entfallen die elektrischen Pumpen für das Zwangsumlaufsystem des Kollektorkreislauf es . Zwangsumlauf ist nur noch für die Hin- und Rückleitung sowie für den Wärmetauscher notwendig. Der elektrische Energieaufwand und der f^egelaufwand werden vermindert.ToI.: The thermosiphon principle eliminates the need for electric pumps for the forced circulation system of the collector circuit. Forced circulation is only necessary for the forward and return lines and for the heat exchanger. The electrical energy consumption and the cleaning effort are reduced.

Zu 2.:Durch das Thermosiphonsystem ist die Gleichmäßigkeit der Durchströmung aller Elemente der Solaranlage gewährleistet.2.: The thermosiphon system ensures uniform flow through all elements of the solar system.

Zu 3.: Der Verrohrungsaufwand der Kollektoren untereinander entfällt, da jeder Kollektor mit eigenem integrierten Wärmetauscher als abgeschlossenes System fungiert. Die Gefahr von Leckagen wird erheblich vermindert.3.: The piping effort between the collectors is eliminated, as each collector functions as a closed system with its own integrated heat exchanger. The risk of leaks is significantly reduced.

Zu 4.: Die zur Verfügung stehenden erheblichen Gesamtlängen des oberen Sammelrohres erlauben den Einbau wirksamer, stromungsgünstiger Wärmetauscher, das den Leistungsaufwand der Pumpen vermindert.4.: The considerable total lengths of the upper manifold available allow the installation of effective, flow-efficient heat exchangers, which reduces the power required by the pumps.

Zu 5.: Da der fekundärkreis physikalisch bedingt mit niedrigerer Temperatur als der Primärkreis betrieben wird, vermindern sich die Energieverluste der Leitungen.5.: Since the secondary circuit is physically operated at a lower temperature than the primary circuit, the energy losses in the lines are reduced.
