Abstract
Description
Die Erfindung betrifft ein Thermo-Transformations Verfahren mit Abwärme betrieben für Heiz- und Kühlzwecke im Kreisprozess, in welches hauptsächlich Niedertemperatur-Wärme zum Einsatz kommt, um das Temperaturniveau zu verbreitern. Eine derartige technische Lösung wird in erster Linie im Bereich der Energiewirtschaft, in der Gebäudetechnik und im chemischen Anlagenbau benötigt.The invention relates to a thermal transformation process with waste heat operated for heating and cooling purposes in the cycle, in which mainly low-temperature heat is used to broaden the temperature level. Such a technical solution is needed primarily in the field of the energy industry, in building technology and in chemical plant construction.
Transformationsprozesse wie der Kaltgas- oder Kaltdampfprozess benötigen je nach Gütegrad einen relativ großen Anteil hochwertiger Antriebsenergie wie Bspw. Strom oder Diesel für die Verdichtung. Absorptionsanlagen erfordern durch das zusätzliche Absorptionsmittel-Zirkulationssystem eine aufwendige Anlagentechnik, sodass Lücken in der Anwendung entstehen. Es ist deshalb Aufgabe der Erfindung, ein Thermo-Transformations-Verfahren mit geringer Antriebsleistung und einfachem Aufbau zu entwickeln.Transformation processes such as the cold gas or cold steam process require, depending on the degree of quality, a relatively large proportion of high-quality drive energy, such as eg. Electricity or diesel for the compression. Absorption systems require complex system technology due to the additional absorbent circulation system, which creates gaps in the application. It is therefore an object of the invention to develop a thermo-transformation process with low drive power and simple design.
Niedertemperaturige Abwärme aus industriellen Verfahren oder aus der Geothermie stehen oftmals im Überfluss zur Verfügung. Koppelt man zwei Gaszylinder mit unterschiedlichen Fluidfüllungen, so entstehen bei gleicher Hubarbeit mit entsprechender Druckanpassung unterschiedliche Temperaturen. Dabei verrichtet der eine Zylinder durch Wärmeausdehnung und Abkühlung Hubarbeit, die im zweiten Zylinder das Gas komprimiert und erwärmt bzw. entspannt und abkühlt.Low-temperature waste heat from industrial processes or from geothermal energy is often available in abundance. If two gas cylinders are coupled with different fluid fillings, different temperatures result for the same lifting work with corresponding pressure adaptation. In this case, the one cylinder performs thermal expansion and cooling lifting work, which compresses the gas in the second cylinder and heats or relaxes and cools.
Die Aufgabe wird erfindungsgemäß im Wesentlichen durch die kennzeichnenden Merkmale der Ansprüche 1 bis 5 gelöst. Zwei durch Kolben gekoppelte Zylinder mit integrierten Wärmeübertragern, die je nach Temperaturbedingung mit diversen Arbeitsfluids gefüllt sind wie z. B. Kohlendioxid als Ausdehnungs- und Argon als Kompressionsmittel, werden in getrennten Zirkulationssystemen mehrere Transformationszellen in einem Modul zusammen geschalten. In Abhängigkeit der Kolbenposition erfolgt die jeweilige Schaltungsoption Kühlen, Regenerieren oder Wärmen. Mit der Erwärmung des Ausdehnungsmittels drückt der fächenangepasste Kolben das Kompressionsgas zusammen, wobei es sich erwärmt. Nach der beidseitigen Wärmeabfuhr sinken die Drücke und der Kolben fährt in die Ausgangslage zurück. Es wird nur Antriebsleistung für die Überwindung der Strömungswiderstande in den Zirkulationssystemen benötigt, da die Kompressionsarbeit von der Volumenänderungsarbeit des Ausdehnungsmittels übernommen wird. Damit ist die Aufgabe geringe Antriebsleistung und einfacher Aufbau gelöst. Mit der Anzahl der Module lässt sich die thermische Leistung bei immer gleichen Transformationszellen an verschiedene Leistungsgrößen anpassen, sodass eine breites Anwendungsspektrum entsteht.The object is achieved according to the invention essentially by the characterizing features of
