Definitions

  • Energy can not be "created” in the sense of being re-created. energy is present in many forms in nature, however not every available form of energy is equal to the human Needs usable. You can, for example, the energy in the wood very well use for heating purposes, but with it relatively poor light or cold for the Refrigerator, etc. produce.
  • the Stirling engine is the second oldest after the steam engine Heat engine, that is, a machine's heat energy in can convert kinetic energy. And although the Stirling engine from the Principle ago has a substantially higher efficiency than the Steam engine and the gasoline or diesel engine, he has not today wider dissemination achieved. While steam engine and gasoline or Diesel engine continuously evolved to be in addition to the satisfied especially the corresponding power densities Achieving significantly increased efficiencies is the Stirling engine almost forgotten. Only recently he wins because of its lower environmental impact and independence from the Heat source increasingly interested. He does, however, have a considerable Pent-up demand for research and development work to a similar "Maturity", as today's steam engines or the gasoline engine in the car too to reach.
  • the ideal Stirling process corresponds to a Carnot process and has therefore a very high efficiency. In practice, however, is one exact implementation, that is an exact replica of the ideal or better not possible of the theoretical process. When running Machines have a number of design-related deviations be tolerated, which adversely affect efficiency and Impact power density.
  • the three types, the ⁇ -, ⁇ - and ⁇ -machine, correspond to the three until now developed basic constructive solutions to the ideal Stirling process as well as possible in the running machines to mimic can.
  • the ⁇ - machine has two pistons in separate cylinders used, with one piston in the hot expansion space and the other Pistons are arranged in the cold compression chamber. Both pistons are ever after operation or crankshaft angle either working piston and then again displacer.
  • a piston and a displacer is used, wherein Both piston and displacer are housed in the same cylinder.
  • Both piston and displacer are housed in the same cylinder.
  • pistons and displacers are in separate cylinders arranged.
  • the complex sealing system of Displacement push rod in the compression piston avoided. For that increased the harmful to the efficiency dead volume.
  • too double-acting Stirling machines designed and executed, in particular of the ⁇ type.
  • the Franchot Stirling engine is known. at This engine runs in the space above the two pistons, but also below the piston each from a Stirling process, that is, the two Cylinders always carry two with the piston top and bottom different working cycles of two different Stirling processes to same time. This limit the two pistons and the associated Cylinder four variable volumes, which in pairs as two separate ⁇ - Machines can be viewed.
  • the single-acting ⁇ - Machine must have the expansion piston and the compression piston Phase shift of about 90 °.
  • Siemens Stirling engine which can be equipped with any number of Cylinders are the standard configuration of the most powerful Stirling engine represents, as the 4-95 'from United Stirling with a Power of approx. 52 kW mechanically. Also in this embodiment are Some designs have been developed, such as the arrangement of the Cylinder in row, as "U”, as "V”, in square or in circle. Although at Siemens - Stirling engine the arrangement of heaters, regenerators and Radiator was chosen so that the sealing of the piston in the Housing wall is in the cold part, remain the principal disadvantages of ⁇ - Machines received.
  • the object of the invention is a method of the type mentioned on the one hand avoids the above disadvantages and that it on the other hand for the first time allows a Stirling engine to be designed so that its approach approached much better to the ideal Stirling process can be as before.
  • the inventive method is characterized in that the Working medium between at least two closed workspaces flows back and forth, wherein for the delivery of useful work the working medium between the workrooms is passed over a working machine, wherein the heat absorption in front of the machine and the heat dissipation after the working machine takes place and that the working medium after the Heat dissipation is compressed in the working space and then by means of of the displacer from one side through the regenerator to the other Side of the displacer flows, whereby the flow of the working medium over Control organs, in particular valves, is controlled and each displacer is moved by a drive.
  • the invention it is possible for the first time To achieve a much higher efficiency than with all previously executed Stirling engines.
  • the higher efficiency is mainly due to the better alignment of the executed work process to the theoretical cycle, which with the method according to the invention is achieved, to lead back.
  • the temperature difference of the working medium in the two coupled Work spaces and the resulting pressure differences it flows into the cold work space and does it over one Work machine work.
  • the resulting equilibrium state is on it attributed to the fact that most of the working medium is in the cold Workspace is located.
  • the pressure difference builds in mirror image Wake up again between the work rooms and will be back over the work Work machine converted to work. This behavior is analogous to a resonant circuit and allows for the same Camot efficiency a higher power density based on the amount of Working medium than the theoretical ideal Stirling process.
  • the working space separated by the displacer in a double-acting workspace thereby The process can run faster because overflow distances are eliminated. About that In addition, any seals omitted from an otherwise necessary Buffer space.
  • each displacer over moved its own drive.
  • crank mechanisms or crank-like drives that are mainly responsible for the poor rimpedement of the executed ones Processes to the ideal Stirling process.
  • crank drives is a Linear drive used, independent of other movements can be controlled so that as many and as long as you like Downtime can be achieved, for example, with the displacers.

  • This version is the so-called "hot” engine.
  • the theoretical efficiency of this type is approximately that of the Camot efficiency, the theoretical power density based on the quantity of the working medium is higher than that of the ideal Stirling process.
  • the working space is through the displacer in two expansion or two compression chambers divided, with the working medium used for work after leaving an expansion space on the assigned this working space Regenerator for delivering useful work on the working machine flows and after the working machine in the compression space of the coupled Workspace flows and then through the movement of the displacer from the compression side by the working space associated with this Regenerator flows into the other expansion space of the working space.
  • this "low temperature” engine allows the use of Low temperature for power generation as well as production of cold.
  • the Heat absorption isobar especially directly, in front of the machine.
  • the main advantage is the fact that the temperature in the displacers is limited to the maximum regenerator temperature, the Regenerator temperature is below the heater temperature.
  • the compression takes place by means of pressure equalization and / or by a compressor. Should the compression take place solely by means of pressure equalization, so eliminates a rotating Machine, so the compressor. The process will certainly be easier. Under Integration of a compressor, an even higher efficiency is achieved.

  • Dead space the volume that is not at the thermodynamic process participates and thus has a detrimental effect on the efficiency. He arises virtually by sinusoidal movement of the working pistons, and real through the volume of the regenerator through which the working medium flows, the heater pipes, etc.
