Abstract
Description
Stand der Technik:State of the art:
Glykol- WassergemischGlycol-water mixture
Herkömmliche Solaranlagen sind mit einem Wasser- Glykolgemisch versehen um das Einfrieren des Kollektors im Winter zu verhindern. Nachteil bei diesen Systemen ist, dass zum einen (aufgrund des Mischungsverhältnisses) nicht gleich viel Energie aufgenommen werden kann wie bei reinem Wasser ohne Frostschutzgemisch, zum anderen besteht die Gefahr, dass sich bei Kollektorüberhitzung das Glykol- Wassergemsich trennt und so 2 getrennte Flüssigkeiten im Kollektor entstehen. Des Weiteren kann überhitztes Glykolgemisch im Solarkreislauf verkleben.conventional Solar plants are provided with a water-glycol mixture around the Prevent freezing of the collector in winter. Disadvantage with these Systems is that on the one hand (due to the mixing ratio) not as much energy can be absorbed as in pure Water without antifreeze mixture, on the other hand there is the danger that at collector overheating the glycol-water chemistry separates and so 2 separate liquids arise in the collector. Furthermore, superheated glycol mixture in Bond solar circuit.
Die Röhrenkollektorkonstruktion verhindert das Leerlaufen des Kollektors bei Frostgefahr.The Tube collector construction prevents emptying of the collector if there is a risk of frost.
Diese Probleme werden mit dem in Schutzanspruch 1; 2 und 3 aufgeführten Merkmalen gelöst.These Problems are with the protection claim 1; 2 and 3 listed features solved.
Der Solarkreislauf bildet ein eigenständiges System mit Wärmetauscher, Regelung und Sicherheitseinrichtungen. Bei Übergabe der Energie an das Heizsystem sind meist mehrere Tauschervorgänge nötig. Bei jedem Tauschvorgang sind Verluste zu beklagen, bzw. muss die Einspeisetemperatur deutlich über der Systemtemperatur liegen. Gerade in den Wintermonaten erreichen die Kollektoren nicht ausreichend Temperaturdifferenz um die Speicher effektiv zu versorgen.Of the Solar circuit forms an independent system with heat exchanger, Regulation and safety devices. When transferring the energy to the heating system usually several exchange operations are necessary. at each exchange process is to be lamented losses, or must the feed temperature clearly over the system temperature are. Just in the winter months reach the collectors are not enough temperature difference around the memory to supply effectively.
Diese Probleme werden mit dem in Schutzanspruch 4 aufgefüherten Merkmalen gelöst.These Problems are with the auffüherten in protection claim 4 features solved.
Bestehende Reinwassersolarsysteme:Existing pure water solar systems:
Bei Drainbacksystemen wird die Solaranlage bei Frost- oder Überhitzungsgefahr in den Speicher entleert. Hierzu ist ein entsprechender technischer Aufwand erforderlich mit entsprechenden Regel- Pumpen und Umstellkomponenten. Zudem ist eine solare Heizungsunterstützung bei Außentemperaturen unter 3°C fraglich (Frostgefahr, der Kollektor wird entleert).at Drainback systems, the solar system in case of frost or overheating dumped in the store. For this purpose, a corresponding technical effort required with appropriate control pumps and changeover components. In addition, a solar heating support in outdoor temperatures below 3 ° C questionable (danger of frost, the collector is emptied).
Bei geschlossenen Reinwassersystemen ist eine entsprechende, technisch aufwendige Regelung erforderlich, aus Sicherheitsgründen für die übrige Heizungsanlage wird auch hier das Solarsystem vom Heizungssystem getrennt. Hierfür sind somit wieder Tauscherverluste zu beklagen.at closed clean water systems is a corresponding, technical complicated regulation required, for safety reasons for the rest of the heating system Here, too, the solar system is disconnected from the heating system. For this purpose are thus again to complain exchanger losses.
Bei beiden Systemen besteht erhebliche Frostschadengefahr wenn der Strom ausfällt, zumal die Kollektor- und Leitungskreise nicht entleert werden können. Die komplette Anlage kann Schaden nehmen.at both systems there is considerable risk of frost damage if the current fails, especially since the collector and circuit circles can not be emptied. The complete system can be damaged.
Die Frostschutzprobleme werden mit dem Schutzanspruch 1; 2 und 3 gelöst. Das Überhitzungsproblem wird mit dem Schutzanspruch 5 gelöst. Bei ausreichendem Solarertrag wird das Kollektorsystem überhitzen. Ein vergrößertes Ausdehnungsgefäß in der Heizungsanlage sorgt für sicheren Betrieb.The Frost protection problems are with the protection claim 1; 2 and 3 solved. The overheating problem is achieved with the protection claim 5. With sufficient solar yield the collector system will overheat. An enlarged expansion tank in the Heating system ensures safe operation.
