  • Machines referred to can be designed for example as piston engines. It is also possible to use hydrodynamic thermal fluid energy machines whose impellers permit a continuous flow of the working gas. Preferably, axially acting turbines or compressors are used. The principle given at the outset is described, for example, according to WO 2009/044139 A2. Here piston machines are used to carry out the method described above. According to US Pat. No. 5,436,508, it is also known that by means of the above-mentioned systems for storing thermal energy, it is also possible to temporarily store overcapacities in the use of wind energy for the production of electrical current, in order to retrieve it if necessary.

  • the charging cycle is realized by a heat pump process.
  • a heat pump process also has the great advantage of being more than 100% efficient, improving the overall efficiency of the process, which is composed of both the charging and discharging cycles.

This also affects their cost-effectiveness, since no increased safety standards have to be taken into account.
  • the abovementioned object is also achieved by the abovementioned system in that the second thermal fluid energy machine has a high-pressure part and a low-pressure part, and in the heat accumulator two fluidically independent piping systems, namely a first piping system and a second piping system are provided , wherein these units are connected in the order given by lines, namely the first line system, then the high-pressure part, then the second line system and then the low-pressure part.

  • structurally separate partial storage can also be easily supplied by two different line systems, as they can each have independent connections for the line system.
  • a special embodiment of the system with structurally separate partial storage is obtained when the first partial storage and the second part memory are arranged in parallel in the charging circuit.

  • the second partial storage which supplies the heat for the low pressure part of the second thermal fluid energy machine with heat, is brought to a lower temperature level. This is the case when the first partial memory is arranged in the charging circuit before the second partial memory, so these are connected in series.
  • the parallel connection of the partial storage has the advantage that the existing material in the partial storage is used optimally in terms of its heat capacity. Moreover, in the case of the parallel connection of the partial memories, it is particularly easy to design them in such a way that both partial memories are simultaneously completely discharged during a discharge cycle and at the same time are completely charged during a charging cycle. However, should it not come to a complete charge or discharge, which is often wind dependent happen, for example, when using the system on a wind turbine, the process can be reversed as often without the charge ratio of the two partial storage is disturbed by this.

As a unit can the heat storage advantageously be made more compact, ie it also has fewer interfaces over which heat can be lost in the environment.
  • the heat accumulator forms a structural unit, then it is advantageous if the first duct system is accommodated in a first partial area and the second duct system is accommodated in a second partial area spatially separated from the first. Spatial separation in the sense of the invention means the greatest possible degree of thermal separation.
  • a thermal separation in a heat accumulator designed as a structural unit is present when the heat-affected zones in the area of the two piping systems are as independent as possible from each other.
  • the first conduit system in the front part of the heat accumulator and the second conduit system may be located in the rear part of the heat accumulator, thus the heat accumulator has spatially two subregions, which differ from the above-mentioned partial memories only in that they are not structurally are separated, but at an interface abut each other.
  • the connections for the charging circuit can then be attached to the heat accumulator in this design so that the first portion and the second portion are arranged in parallel in the charging circuit.
  • the second line system is accommodated in a partial region of the heat accumulator together with the first line system. This means that run in this area, the second conduit system and the first conduit system in the same heat-affected zone of the heat accumulator.

Abstract

L'invention concerne un procédé de charge et de décharge d'un accumulateur de chaleur (11) au cours d'un cycle de charge (13) et au cours d'un cycle de décharge (14). Selon l'invention, la décharge s'effectue au moyen d'une turbine à vapeur (23) qui présente une partie haute pression (HP) et une partie basse pression (LP). Afin d'alimenter les deux parties de la turbine en chaleur, l'accumulateur de chaleur (11) est divisé selon l'invention en une partie (20) pour la haute pression (HP) et en une partie (21) pour la basse pression (LP) (cette division ne doit pas s'effectuer au niveau de la construction). L'invention concerne par ailleurs une installation, dans laquelle l'accumulateur de chaleur (11) est divisé en deux parties (20, 21). Le fait que la turbine fonctionne avec une partie haute pression (HP) et une partie basse pression (LP) permet d'obtenir de manière avantageuse l'augmentation avantageuse du rendement de chaleur provenant de l'accumulateur de chaleur (11). Il est par exemple possible de tirer parti de l'installation pour l'accumulation temporaire des productions excédentaires d'une éolienne (16).
