Nachteile des Standes der TechnikDisadvantages of the prior art
Bei einem Arbeitstemperaturbereich von <100°C steht der Anlagenwirkungsgrad unter 10% in Verbindung mit einem sehr hohen technischen Aufwand.With a working temperature range of <100 ° C, the system efficiency is below 10% in connection with a very high technical effort.
Die mechanischen Anlagen sind Sonderanfertigungen und können nicht mit handelsüblichen Elementen hergestellt werden. Zum Beispiel werden in ORC Anlagen hauptsächlich sehr teure Turbinen als Expansionsmaschinen eingesetzt. Aus diesem Grund sind micro Systeme mit einer Leistung unter 10 KW kaum verfügbar. Ein nicht zu unterschätzender Punkt ist die aufwendige Schmierung der beweglichen Teile im gesamten Arbeitsfluidkreislauf.The mechanical systems are custom-made and cannot be manufactured with off-the-shelf elements. For example, very expensive turbines are mainly used as expansion machines in ORC systems. For this reason, micro systems with a power below 10 KW are hardly available. A point that should not be underestimated is the complex lubrication of the moving parts in the entire working fluid circuit.
Als Arbeitsfluid kommen hauptsächlich organische Flüssigkeiten mit einer niedrigen Verdampfungstemperatur zum Einsatz. Es handelt sich hierbei um umweltkritische Flüssigkeiten die auch als Kältemittel, in Klimageräten und Kühlanlagen, bekannt sind. Energiegewinnungsmaschinen auf Basis von fossilen Brennstoffen werden hier nicht betrachtet, da sie in einem Temperaturbereich weit über 100 °C arbeiten, mit den bekannten Auswirkungen für Klima und Umwelt. Zusätzlich werden für neue und umweltfreundliche Motorenkonzepte immer höhere Anforderungen an die Kraftstoffe gestellt, diese sind wahre High-tech Produkte. Die Zukunft der Verbrennungsmotore liegt in den „Designer Kraftstoffen“.Organic liquids with a low evaporation temperature are mainly used as the working fluid. These are environmentally critical liquids that are also known as refrigerants in air conditioning and cooling systems. Energy generation machines based on fossil fuels are not considered here, as they work in a temperature range well above 100 ° C, with the known effects on the climate and the environment. In addition, ever higher demands are placed on the fuels for new and environmentally friendly engine concepts; these are true high-tech products. The future of internal combustion engines lies in “designer fuels”.
Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist ein sehr einfach gehaltener Anlagenaufbau zur Umwandlung von Wärmeenergie in mechanische Energie. Das Arbeitstemperaturfenster kann beliebig und einfach, je nach vorhandener Wärmequelle, verschoben werden.The object of the invention is a very simple system structure for converting thermal energy into mechanical energy. The working temperature window can be shifted as desired and easily, depending on the available heat source.

Die Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a device with the features of
Vorteile der ErfindungAdvantages of the invention
Durch den einfachen Aufbau ergeben sich geringe Investitionskosten. Die industrielle Prozessabwärme (Abfallwärme) kleiner 80°C wird zur Energiegewinnung genutzt. Es wird nicht nur die Abfallwärme recycelt sondern das Verfahren ist zu 100% emissionsfrei. Die Anlage hat einen sehr niedriger Geräuschpegel, einen hohen Wirkungsgrad und ist nahezu wartungsfrei. Es werden wenig seltene Erden und Silizium (Photovoltaik) verwendet. Die Anlage arbeitet auf einem „Klimaschädlichen Minimal Level“ (KML).The simple structure results in low investment costs. The industrial process waste heat (waste heat) below 80 ° C is used to generate energy. Not only is the waste heat recycled, but the process is 100% emission-free. The system has a very low noise level, a high degree of efficiency and is almost maintenance-free. Little rare earths and silicon (photovoltaics) are used. The system works on a "climate-damaging minimal level" (KML).
Die erforderlichen Temperaturdifferenzen liegen weit unter denen von Verbrennungsmotoren und Dampfmaschinen dabei ist der Arbeitstemperaturbereich extrem groß.The required temperature differences are far below those of internal combustion engines and steam engines, while the working temperature range is extremely large.
Es werden keinerlei Anforderungen an die Art der Wärmeerzeugung gestellt. Da es sich um ein geschlossenes System handelt und ohne Verbrennung/Oxidation auskommt ist eine Anwendung im Weltall gegeben. Diese Erfindung kann man als Vielstoffenergiegewinnungsanlage mit einem extrem großen Arbeitstemperaturbereich bezeichnen, somit ist diese Erfindung unter anderem für den Einsatz nach Naturkatastrophen für die Notstrombereitstellung prädestiniert.There are no requirements for the type of heat generation. Since it is a closed system and does not require combustion / oxidation, it can be used in space. This invention can be described as a multi-fuel energy generation system with an extremely large working temperature range, so this invention is predestined, among other things, for use after natural disasters for the provision of emergency power.
Die Temperaturschwankungen zwischen Tag und Nacht sind für die Energiegewinnung nutzbar, das ist besonders für Solarthermieanlagen interessant, diese produzieren in den Sommermonaten extrem viel nicht verwertbare Wärme und müssen daher abgeregelt werden.The temperature fluctuations between day and night can be used for energy generation, which is particularly interesting for solar thermal systems, these produce an extremely large amount of unusable heat in the summer months and must therefore be regulated.
Diese Erfindung kann ebenfalls zur Kühlung eingesetzt werden.This invention can also be used for cooling.
