Abstract

The vapour pressure is used to move a double acting piston in a cylinder, the piston rod of which is connected to the armature of a linear generator. The armature is moved in the magnetic field of the generator stator. A condenser is connected to the cylinder, in which the vapour is liquefied by cooling, and is supplied to the collector via a tank. Magnetic valves(1-7) and limit switches are provided for the automatic operation of the generating plant. ADVANTAGE - Efficiency increased and price considerably reduced by achieving 600 per cent increase in current generated with a collector surface requirement reduced by 500 per cent.

Description

Die Erfindung bezieht sich auf einen Solargenerator der im Oberbegriff des Patentanspruchs beschriebenen Gattung.The invention relates to a solar generator in the Preamble of the generic type described.

Anlagen zur Umwandlung von Solarstrahlung in elektrischen Strom bestehen in der Regel aus Solarzellen auf Siliziumbasis, deren Wirkungsgrad in der Praxis bei 10% liegt. Der Preis einer Photovoltaikanlage mit 50 m2 Solarzellen und einer Spitzenleistung von 5 kW beträgt zur Zeit etwa 125 000 DM.Plants for converting solar radiation into electrical power usually consist of silicon-based solar cells, the efficiency of which is 10% in practice. The price of a photovoltaic system with 50 m 2 solar cells and a peak output of 5 kW is currently around 125,000 DM.

Der Erfindung liegt die Aufgabe zugrunde, die Nutzung der erneuerbaren Energie Solarstrahlung zur Umwandlung in elektrischen Strom erheblich zu verstärken. Dies ist möglich durch Anlagen, deren Wirkungsgrad erheblich höher und deren Preis erheblich niedriger liegt und damit die Anzahl der Anwender erheblich steigen läßt.The invention has for its object the use of renewable energy solar radiation for conversion into electrical To amplify electricity significantly. This is possible through systems whose Efficiency significantly higher and the price is significantly lower and thus the number of users can increase significantly.

Diese Aufgabe wird durch die Kennzeichnungsmerkmale des Patentanspruchs gelöst. Der Solargenerator mit einer Spitzenleistung von z. B. 5 kW ist so konzipiert, daß er aus 8-9 m2 Kollektoren besteht, die mit einer niedrigsiedenden Flüssigkeit gefüllt sind (z. B. Äther, Ammoniak, Propan, R22). Die Kollektoren sind durch eine Rohrleitung mit einem Zylinder mit doppeltwirkendem Kolben, einem Kondensator und einem Sammler verbunden und bilden einen geschlossenen Kreislauf.This object is achieved by the characterizing features of the patent claim. The solar generator with a peak output of e.g. B. 5 kW is designed so that it consists of 8-9 m 2 collectors, which are filled with a low-boiling liquid (z. B. ether, ammonia, propane, R22). The collectors are connected by a pipe to a cylinder with a double-acting piston, a condenser and a collector and form a closed circuit.

Wie in zugehöriger Zeichnung dargestellt, wird durch Aufheizung mit Solarenergie die Flüssigkeit im Kollektor verdampft. Durch den entstehenden Dampfdruck wird der Kolben im Zylinder bewegt, der einen Generator antreibt, in dem elektrischer Strom erzeugt wird. Hat der Kolben die Endstellung einer Bewegungsrichtung erreicht, werden durch Endschalter Magnetventile geschaltet, die die andere Bewegungsrichtung freigeben. Der dabei ausgestoßene Dampf wird einem Kondensator zugeführt, kondensiert und erzeugt damit einen Unterdruck. Die Flüssigkeit wird einem Sammler zugeführt, aus dem eine Pumpe den Kollektor versorgt. Der Flüssigkeitsstand im Kollektor wird durch einen Schwimmerschalter geregelt. Während des Nachförderns werden Magnetventile so geschaltet, daß die Pumpe mit geringster Energie laufen kann. Genutzt wird die Druckdifferenz zwischen Kollektor und Kondensator, die um soviel größer ist, je höher die Temperaturdifferenz zwischen beiden ist. Je nach eingesetzter Flüssigkeit kann so ein Anlagenwirkungsgrad von ca. 60% erreicht werden. Eine 5 kW-Anlage benötigt nur 8-9 m2 Kollektoren und kann zu einem Preis von ca. 30 000 DM erstellt werden. Damit wird der Nutzung von Solarenergie ein erheblich breiteres Anwendungsfeld erschlossen.As shown in the accompanying drawing, the liquid in the collector is evaporated by heating with solar energy. The resulting steam pressure moves the piston in the cylinder, which drives a generator in which electrical current is generated. When the piston has reached the end position of one direction of movement, solenoid valves are activated by limit switches, which release the other direction of movement. The steam emitted is fed to a condenser, condensed and thus creates a negative pressure. The liquid is fed to a collector, from which a pump supplies the collector. The fluid level in the collector is controlled by a float switch. During re-feeding, solenoid valves are switched so that the pump can run with the lowest energy. The pressure difference between the collector and the condenser is used, which is greater the higher the temperature difference between the two. Depending on the liquid used, a system efficiency of approx. 60% can be achieved. A 5 kW system only requires 8-9 m 2 collectors and can be built at a price of around 30,000 DM. This opens up a considerably broader field of application for the use of solar energy.
