Definitions

  • the invention relates to a radiator for room air heating with convectors acted upon by heating media from different energy sources and at different temperature levels, which carry heat-conducting fins, which, according to their temperature level with thermal insulation distance between them, divide an air duct in the direction of flow into many rising, open at the top and bottom .
  • Such multivalent radiators are used, for example, to a conventional convector by connecting a z. B. to support with solar energy or flue gas operated convector.
  • the known multivalent heating system according to DE-A-2 945 071 has the disadvantage that the overall efficiency is impaired by thermal feedback, be it by turbulence in the air flow or by conduction of heat from the convector system to the convector system at a lower temperature and the efficiency remains below 50%.
  • the invention is therefore based on the object of suppressing the thermal feedback from the convector system to the convector system of low temperature in the multivalent radiator system of the type described in DE-A-2 945 071.
  • This object is achieved in that the slats of the convector of higher temperature with the slats of the convector of low temperature are connected with each other by keeping the open cables by thermal bridges made of a poorly conductive material. This results in a multivalent heating system with undisturbed laminar air flow and practically non-reactive heat exchange in several, spatially and thermally superimposed stages. This creates a so-called mode of operation between the upper convector with a higher working temperature and the lower convector with a lower working temperature.
  • the fins are arranged at a heat-insulating distance from one another.
  • the invention is primarily concerned with excluding feedback via the shaft wall.
  • the arrangement of heat-insulating zones made of heat-insulating solid material is particularly important in the area of the adjacent lamella edges in order to avoid air vortices in this area.
  • it is even more important to exclude the heat conduction from the convector to the convector of lower temperature, which is present in the known radiator according to DE-A-2 945 071 via the shaft wall.
  • this heat conduction is suppressed in the invention in that the heat feedback is also suppressed via the path of indirect heat conduction via the shaft wall through thermal insulation zones.
  • the examples of a multivalent radiator shown in the drawing are used for room air heating with convectors acted on from different energy sources, a lower convector 1 and an upper convector 2.
  • the convectors 1 are arranged in a common air duct. They are operated by heating media M 1 and M 2 from different heating sources, the upper convector 2 from a conventional heating source, the lower convector 1 from an auxiliary heating source, in particular for the use of solar energy.
  • the tubular convectors 1 and 2 are covered with rectangular slats 3 and 4. Between the convector zone a of the lower temperature and the convector zone c of the higher temperature there is a transition zone b in which the lamellae 3 and 4 forming vertical trains 14 are separated from each other, either by a separation gap 8 or by insulating bridges 11 poorly heat-conducting material, for example plastic (see FIGS. 6 and 7).
  • the shaft 5 is formed by a metallic one running from top to bottom Shaft wall 5 limited.
  • a heat insulation zone is switched on in the heat conduction path from the convector zone c to the convector zone a in order to prevent thermal feedback via heat conduction paths.
  • the outer metallic shaft wall 5 is lined overall by an inner insulating wall 6 made of plastic or other, poorly heat-conducting material to form the thermal insulation zone. 3, this lining can be interrupted in the transition zone b.
  • FIG. 4 the lining is replaced by insulation strips 7 with which the slats 3, 4 are connected to the metal shaft wall 5.
  • the lining can also, as FIG. 9 shows, be designed as an insulation collar, which adjoin one another from lamella 3 to lamella 4 and likewise form a continuous lining.
  • FIGS. 6 and 7 show lamellae 3, 4 with a solid body connection by means of insulating bridges 11.
  • This embodiment is distinguished in particular by that continuous, that is, uninterrupted trains 14 are formed via the convector systems, which ensure an undisturbed ascending laminar air flow which is only subjected to the thermals. This prevents feedback from both heat conduction and air flow due to eddy formation.
  • FIG. 5 shows an embodiment in which the slats 4 of the upper convector 2 are connected directly to the metal shaft wall 5.
  • the feedback by heat conduction to the lower convector 1 is avoided by switching on an insulation barrier 9 between the metallic wall above and below. If heat radiation is to take place in the area of the upper convector 2, the slats 4 of this convector 2 can be connected in a heat-conducting manner to the upper shaft wall 5 ′′, while the slats 3 of the lower convector 1 against the lower metal shaft wall 5 ′ through an insulating wall or through Insulation strips 7 are thermally insulated, which means that the thermal energy of the lower convector 1 is largely used to support the upper convector 2.
  • a flap 15 can be provided on the upper exit side of the shaft, through which a baffle surface for deflecting the warm air, This flap 15 can also be arranged so that it can be deflected so that, if necessary, the warm air flow is deflected away from the window front into the room.
