Abstract

Vorrichtung zum Erzielen einer isotherme ähnlichen Kompression oder Expansion eines Gases, dadurch gekennzeichnet, dass dünne kreisrunde Metallscheiben mit guter Wärmeleitfähigkeit die federnd aneinander liegen einen Zylinderraum einer Arbeitsmaschine gleichmäßig verteilt, ausfüllen. An apparatus for obtaining a similar isothermal compression or expansion of a gas, characterized in that thin circular metal disks having good thermal conductivity which lie resiliently against each other a cylindrical space is distributed evenly fill a work machine.

Description

  • Die Erfindung betrifft eine Vorrichtung zum Erzielen einer Isotherme ähnlichen Kompression oder Expansion eines Gases. The invention relates to a device for achieving an isotherm similar compression or expansion of a gas.
  • Bei der Kompression oder Expansion eines Gases verläuft die Druck-Volumenkurve wenn keine Wärme zu oder abgeführt wird, nach einer Adiabaten. In the compression or expansion of a gas, the pressure-volume curve is when no heat is dissipated to or after an adiabatic.
  • In der In the DE 27 36 472 B1 DE 27 36 472 B1 wird eine Hubkolbenmaschine beschrieben bei der zum besseren Wärmeübergang im Arbeitsraum Vorsprünge mit korrespondierenden Nuten angeordnet sind, um die Oberfläche des Arbeitsraumes zu vergrößern. a reciprocating piston machine is described in the projections with corresponding grooves are arranged for better heat transfer in the working chamber in order to increase the surface area of ​​the working space. Die Vorsprünge sind jedoch fest mit dem Kolben bzw. Zylinder verbunden. The projections are, however, fixedly connected to the piston or cylinder.
  • Aufgabe der Erfindung ist es, eine möglichst isotherme Verdichtung oder Expansion eines Gases ohne großen baulichen Aufwand zu erzielen. Object of the invention is to achieve an isothermal possible compression or expansion of a gas without major construction effort.
  • Dies wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 erreicht. This is achieved by a device having the features of claim 1.
  • Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben. Advantageous embodiments are described in the subclaims. Mit der neuen Vorrichtung verläuft Druck-Volumenkurve nahezu isothermisch. With the new device pressure-volume curve is nearly isothermal.
  • Der Carnotsche Kreisprozess kann jetzt weitgehend durchgeführt werden. The Carnot cycle can now be largely carried out. Dadurch ist es möglich eine Wärmepumpe zu bauen, welche Wärme aus der Luft holt mit weniger zusätzlicher Energie als bisher. This makes it possible to build a heat pump, which heat from the air brings with less additional energy than before.
  • Die neue Vorrichtung besteht erfindungsgemäß aus vielen dünnen kreisrunden Metallscheiben mit guter Wärmeleitfähigkeit und federnden Eigenschaften. The new device is the invention of many thin circular metal discs with good thermal conductivity and resilient properties. Legt man die Scheiben auf den Zylinderboden aufeinander, so liegt abwechselnd eine ebene und eine federnde Scheibe übereinander. Taking the slices on the cylinder base to each other so located alternately above one another a flat and a resilient washer. Durch diese Federung (siehe Through this suspension (see 1 1 u. u. 2 2 ) haben die Scheiben einen gleichmäßigen Abstand voneinander und füllen den Zylinderraum aus. ) Have the discs a uniform distance from each other and fill the cylinder room. Die dazwischenliegende Luft gibt beim Zusammendrücken des Zylinderraumes die entstandene Wärme an die Scheiben schnell ab, da sie eine bis zu 100 mal größere Oberfläche haben als der Zylindermantel. The intervening air is the compression of the cylinder chamber, the resulting heat to the discs quickly, as they have up to 100 times more surface area than the cylinder jacket. Durch die viel größere Wärmespeicherfähigkeit der Scheiben gegenüber der Luft erwärmen sich die Scheiben nur wenig und lassen während der Kompression nur eine kleine Differenztemperatur zwischen Scheiben und Luft zu. By the much larger heat storage capacity of the discs to air the discs heat up only slightly, leaving only a small temperature difference between discs and air during compression. Die Geschwindigkeit der Kompression bestimmt die Differenztemperatur, welche für den Wärmeübergang zwischen Scheiben und Luft notwendig ist. The rate of compression determines the temperature difference, which is necessary for the heat transfer between the discs and air. Die Druck-Volumenkurve wird nahezu isotherm. The pressure-volume curve is nearly isothermal. Dasselbe gilt auch für die entstehende Kälte bei der Expansion wenn die Scheiben im Zylinderraum verteilt sind. The same also applies to the resulting refrigerant in the expansion when the discs are distributed in the cylinder chamber.
  • Auf den Scheibenpaket liegt ein Deckel mit dem man die Scheiben auf den wärmeleitfähigen Zylinderboden aufdrücken kann. On the disc pack is a cover with which you can impress the discs on the heat conductive cylinder base. Die fest aufeinanderliegenden Scheiben können ihre Wärme oder Kälte an den Zylinderboden abgeben, der wiederum von Flüssigkeit durchflossen wird mit der die Wärme oder Kälte zu einen Wärmetauscher (Heizkörper) oder Außenluftwärmetauscher fließen kann. The fixed superposed discs can give their heat or cold to the cylinder bottom, which is in turn traversed by the liquid to flow with the heat or cold to a heat exchanger (radiator) or the outside air heat exchanger. Umgekehrt lassen sich die Scheiben im zusammengedrückten Zustand auch vom Zylinderboden erwärmen wenn die Scheiben um einen Differenzbetrag von beispielsweise 5 Grad kälter sind als der Zylinderboden. the disks in a compressed state can be Conversely, also heat from the cylinder base when the discs are colder to a difference of, for example, 5 degrees as the cylinder base. Dieser ist mit einen Außenluftwärmetauscher mit einer Kühlflüssigkeit verbunden, so daß die Außenluft die Scheiben aufheizt. This is connected to an outside air heat exchanger with a cooling liquid, so that the outside air heats the slices. Das zusammengedrückte Scheibenpaket hat keinen Einfluß auf die Temperaturentwicklung bei der Kompression oder Expansion im Zylinderraum. The compressed disc package has no influence on the temperature development in the compression or expansion in the cylinder chamber. Die Temperatur verläuft in beiden Fällen adiabatisch. The temperature is adiabatic in both cases.
  • Auch mit nicht federnden ebenen Scheiben und zusätzlichen Druckfedern lassen sich die Abstände der Scheiben zueinander verändern, wobei die Scheiben (siehe Even with non-resilient planar slices and additional compression springs, the distances of the disks can be changed to each other, said disks (see 3 3 u. u. 4 4 ) von den Druckfedern mitgenommen werden. ) Are carried along by the pressure springs.
  • Die 3 Mitnehmergabeln an den Scheiben sind am Schraubenfederumfang verteilt, damit sie sich beim Zusammendrücken nicht behindern. The three Mitnehmergabeln on the discs are distributed around the coil spring extent that they do not interfere with the compression.
