Definitions

  • a heat flow for producing a favorable temperature for driving on the road surface between this and a heat accumulator, in the sense of a heat source or heat sink, is produced, whereby in addition to artificial heating devices, natural heat storage and also several and Different types can be used side by side if means are provided that influence the heat flow in the desired direction, that is, for heating or cooling.
  • Such methods are used to keep roadways passable in winter, especially during take-off and landing at airports, if possible avoiding the use of chemical additives, and to reduce tire wear at higher temperatures.
  • the invention aims at a method which can also be used with existing road surfaces, the installations required for this being simple in terms of the benefits and with which the energy transport is kept as low as possible.
  • the special features of operating a road can be taken into account insofar as a lower heat flow is maintained for less traveled side areas and the size of the partial heat
  • the individual heat blocks of the roadway can be changed and tuned according to the prevailing conditions and requirements.
  • this adaptation to the temperature conditions, both in the road surface and in the heat accumulator, can be carried out over a very wide range. It is particularly advantageous to be able to change the size of the heat flow during operation of the roadway, as a result of which energy-saving methods can be used.
  • the production of uniform temperatures on the road surface is possible by suitable subdivision into heat flow longitudinal sections in the longitudinal direction of the road, the length of which can be adapted to the conditions of the road and the heat transfer and where combined with a simple circulation of the heat transfer medium, a high degree of utilization applied heat flow can be achieved.
  • the pipeline network is used for the implementation of the method in the pavement is arranged in a correspondingly favorable manner, particularly with regard to the depth of the laying and the spacing of the pipes, and is broken down into parts which correspond to the distributions of the heat flow.
  • the subdivision of the pipeline network permits an advantageous arrangement of the pipelines with regard to the distribution of the heat flow in the road surface and thus on the road surface.
  • the supply and discharge lines of the pipeline network can be installed inside or outside the road surface.
  • the arrangement of the pipelines of the pipeline network can be provided according to the geometric and thermal requirements of the carriageway and the requirements for the production of the appropriate heat flow and can be influenced by the piping dimensioning and its laying in the pavement, which is particularly simple if this part of the pavement is retrofitted is applied to an existing road surface, the application of an intermediate layer to be insulated downwards to save energy also being particularly advantageous.
  • the heat flow can also be influenced favorably by the selection of the shape of the pipes and their orientation in the road surface.
  • frost-protected heat transfer medium is favorable for the safe operation of the installation.
  • the supply and discharge lines of the pipeline network are advantageously carried out in a densely packed form because of the small available thickness of the pavement and in order to change as little as possible the heat flow through the road surface in the area of the supply and discharge lines.
  • the purpose of economical use of the installation means can be taken into account by designing and arranging the inlets and outlets to the parts of the pipeline network, the cheapest solution being determined by the conditions of the carriageway, in particular with regard to its dimensions, its position to other carriageways and its climate .
  • the utilization of the heat transport by using a circuit of the pipeline network in which the parts of the pipeline network are connected in series in areas of different partial heat flows of a longitudinal pipeline section is particularly effective.
  • the heat transfer medium can also be used economically if there are two adjacent pipelines along the length sections of the roadway are connected to common heat transfer devices.
  • a simplification of the installation can also be achieved if the supply and discharge lines to the pipeline network alternate between the longitudinal pipe sections, which results in a simpler arrangement of the heat transfer means and the line routing.
  • the arrangement of combined heat and power plants is particularly advantageous in connection with heat pumps, which are also conveniently arranged alternately with only heat pumps, the latter being used to reheat or cool the heat transfer medium before re-entering the pipeline network.
  • Another advantage is the ability to operate the heat pumps with the electrical energy generated by the combined heat and power plants.
  • a detailed regulation is particularly advantageous, which regulates the flow of the heat transfer medium by means of control valves flows and which are controlled by a heat flow controller, depending on certain, essential temperatures and conditions of the overall system.

Abstract

Un procédé permet d'assurer une température de surface favorable aux déplacements sur une surface de circulation, notamment des pistes de décollage et d'atterrissage d'avions. La surface (2) de la piste est subdivisée transversalement à son sens longitudinal (20) en blocs de flux thermique (14, 14', 15, 15') dont la densité de flux thermique est individuellement ajustée en fonction de la fréquence de la circulation et de la température de la surface (2) de la piste. La surface (2) de la piste est subdivisée dans le sens longitudinal (20) en sections longitudinales de flux thermique (19, 19', 19'', 19'''). Les subdivisions du flux thermique (4, 4', 4'', 4''') correspondent à des subivisions d'un réseau de canalisations (16) incorporé au revêtement (3) de la piste, qui assure le flux thermique (4) entre des accumulateurs de chaleur (10) et la surface (2) de la piste au moyen de dispositifs de chauffage (43) et d'échangeurs de chaleur (13).
