  • the pipes 9 running in the panel 1 can be incorporated during the manufacture of the graphite panel 1 .
  • the pipes 9 preferably comprise pipes made of metal, for example copper, or plastic pipes, for example made of polypropylene or cross-linked polyethylene. However pipes made of metal are to be preferred because of the better heat transfer.

  • a certain proportion of the thermal energy stored in a heating or cooling medium passed through the pipes 9 can initially be passed by heat conduction from the pipes 9 to the free principal surface 13 of the panel 1 and released from there by thermal radiation and free convection to the room R to be temperature controlled.
  • This release of heat (or release of cold when a cooling medium is passed through the pipes) takes place very rapidly with the result that the room can be heated (or cooled) very rapidly.
  • Another portion of the thermal energy stored in the heating or cooling medium is transferred by heat conduction from the pipes 9 via the heat conducting panel 1 to the thermal accumulator formed by the component 5 .
  • the thermal accumulator is heated (or cooled when a cooling medium is passed through the pipes).
  • the thermal accumulator can then release the thus intermediately stored thermal energy in a time-delayed manner to the room, where the good thermal conductivity of the panel 1 ensures that this is accomplished largely free from losses.
  • the heating (or cooling) of the room R accomplished in this manner takes place on a longer time scale (of a few hours).
  • the temperature control system according to the invention is therefore able to bring the room R to be temperature controlled to a desired room temperature both rapidly and also slowly using the thermal accumulator.
  • a cooling medium for example cold water
  • the temperature control system in winter during the day can firstly be heated for instantaneous heating of the room by passing a heating medium through the pipes. At the same time the thermal accumulator is loaded with heat. At night the flow of the heating medium can be stopped since the time-delayed release of heat from the loaded thermal accumulator is sufficient to keep the room at a (lower) room temperature at night.

  • a graphite panel 1 is inserted in the frame 2 .
  • the composition of the graphite panel 1 corresponds to the panel 1 of the exemplary embodiment from FIG. 1 .
  • pipes 9 are also embedded in the graphite panel 1 and run there in a serpentine, grid, spiral or meander shape.
  • the graphite panel 1 is preferably adhesively bonded flat on the surface 11 of the component 5 by means of a thermally conductive adhesive 4 .

  • the non-woven fabric 3 and the graphite film 15 disposed thereon preferably comprises a non-detachable composite which can be produced for example by calendering.
  • a non-detachable composite can particularly expediently be produced from a carbon fibre non-woven and a graphite film 15 of expanded graphite.

It is particularly appropriate to use a perforated graphite film 15 .
  • Perforation of the graphite film specifically increases its flexibility and thereby facilitates the handling of the film. Since graphite comprises a brittle material, there is the risk of the film tearing or breaking when handling thin films of expanded graphite. This risk can be reduced significantly by perforation of the graphite film 15 .
