Definitions

  • the invention relates to a heating system for charging rooms with heated air according to the preamble of the main claim.
  • Such heating systems are generally known.
  • tiled stoves each covering several rooms with one part
  • the tiled stoves being designed in such a way that hot air can escape from them, for which purpose such tiled stoves have to be equipped with special hot air generating rooms.
  • the hot air heaters of this type are due to the difficult treatment of the hot air flow with relatively low temperatures up to max. 60 - 70 ° C be driven.
  • the approach of higher temperatures was automatically forbidden, since the relatively large outlet openings of the distribution channel system open directly into the rooms. It was previously not possible to install hot air heating systems in the sense of the most widespread central heating systems, i.e.
  • Hot air generators are not generally known and in use, but these are devices that are installed or installed at a suitable point in the room to be heated and in which the air drawn in on one side after passage through one in the device arranged heat exchanger, the heated air is simply blown out on the other side. Such hot air generators are therefore not suitable for charging hot air space heaters.
  • the invention is therefore based on the object to provide a heating system that can be operated with hot air at a much higher temperature level than was previously possible and to train both the heat generator and the actual heat emission device so that they are suitable for this purpose .
  • This inventive design of the system and the essential parts of the system creates the possibility of pressing the heat transfer medium air with a sufficiently high pressure through the hot air generator and specifically to promote trained heat emitting devices and also to be raised to a much higher temperature level than was possible and envisaged with previous warm air heaters by the heating surface enlarging and flow path extending elements in the hot air generator.
  • the air in the hot air generator according to the invention is guided in countercurrent through this, resulting in a significantly higher heat transfer coefficient and the hot air generated leaving the generator at a temperature of maximum 300 ° C and at this high temperature can get into the small-diameter (approx. 50 mm) line distribution system and thus into the special heat-emitting devices, which are preferably and advantageously designed in accordance with claim 7.
  • a heating element is created with which only the installation of a central heating system based on hot air is considered and to which the air with relatively high temperatures and relatively high pressure can also be supplied.
  • High temperatures can be taken into account here because the air does not emerge from any opening in the room as a large-diameter hot air stream, but from several small openings, although, and this is essential, the air jam that inevitably results in the device, approximately 2 / 3 of the heat content of the hot air within the device to the refractory shaped body (tiles) and can thus be converted into radiation.
  • the heat-emitting device is a kind of tiled stove, which does not have its own furnace, but receives its energy supply from the central hot air generator via easy-to-install and relatively small-diameter lines, which is located at a suitable point (e.g. cellar room) , but also in the relevant apartment itself. Because the heat transfer air is directly in If the rooms to be heated exit through the small air outlet holes of the heat emission device, the system advantageously does not need any return lines. In addition, such a system equipped with such devices can be controlled practically as well as the central heating systems which are customary today and in which water is used as the heat transfer medium. If temperature-controlled control flaps are not arranged directly behind the hot air generator or the line distributor in the lines, each of the devices according to the invention belonging to a system is advantageously and preferably equipped directly with such a control flap.
  • the device has the advantage that a feeling of comfort can be achieved quickly even at relatively low room temperatures (for example. 18 ° C.).
  • the heat emission device and the entire heating system belonging to it are accessible for humidification and dehumidification, and the entire system can even be used as a cooling system if necessary.
  • one device for example, can only be an integral part of a tiled stove-like brickwork, which is preferred, in particular when two adjacent parallel housing large areas are tiled are equipped, it is also possible to easily install such a device in a room partition, so that two rooms can be heated by one device.
  • FIGS. 1-4 First, reference is made to FIGS. 1-4 and the hot air generator.
  • the hot air generator consists in principle of a housing 1 with air inflow and outflow openings and of the energy converter 2 arranged in the housing and capable of being flushed with blower air.
  • the vertically arranged, columnar and externally heat-insulated housing 1 and on the other hand the energy converter 2nd Limited space 3 is divided into elements 6 which enlarge the heating surface, extend helically and extend the flow path and in front of the upper air inflow opening 4 there is a soundproofed chamber 8 provided with air inflow openings 7, in which the fan 9 is arranged.
  • the chamber 8 is advantageously arranged directly on the housing 1 and the blower 9 is connected on the pressure side directly to the air inflow opening 4 to the housing 1 or the space 3 located therein.
  • an air filter 10 is also interchangeably arranged between the air inflow openings 7 and the suction side of the blower in order to keep the air pressed by the hot air generator free of dust, which is advantageous, since the hot air generated is from the special to be charged Radiators is blown directly into the rooms to be heated and the filter permanently filters out the air in the room and breathing.
  • the housing 1 is a hot air generator with an energy converter for liquid fuels, which in this respect resembles a conventional oil stove. However, this is arranged centrally within the housing 1 and the heating surface enlarging and, which is essential, flow path lengthening element 6 is in the form of a heat-conducting connection to the energy converter 2 and helically surrounding the flow guide surface 6 'over its entire length.
  • the housing 1 is expediently designed such that, for example, the energy converter with its flow guide surface 6 'attached to it can be easily inserted, for example from above or below, into the housing 1 and fixed in a suitable manner.
  • a bypass channel 13 leading from the inflow to the outflow opening 4, 5 of the housing 1 can advantageously be arranged here, which, as can be seen, is provided on the inflow side with an air distributor flap 4 ′ which is also effective for the inflow opening 4.
  • the air blown in by the blower 9 can either pass through the space 3 with its storage stones 11 or the bypass duct 13, or these two parts are acted upon more or less uniformly with subsequent air mixing, as a result of which an adjusted air mixing temperature is achieved can.
  • the associated regulating and control circuit 15 is shown schematically on the left next to the housing 1 and does not require any further explanation insofar as these are regulating and control processes as are common in the heating field.
  • the hot air generator in a hot air space heating system illustrated in FIG. 4, from which it can also be seen that the chamber 8 with the fan 9 is not necessarily on the housing se 1 of the hot air generator must be placed. In such a case, it is also possible, as illustrated, to set up the hot air generator directly in a suitable living space and to surround it with tiles and to connect the heat emitting devices 16 to it by means of a corresponding duct system 17.
  • the described construction principle of the hot air generator can of course also be applied to open fireplaces, the space 3 being articulated to extend the flow path surrounding the walls of the open fireplace.
  • Fig. 5 the entire heating system is shown very strongly schematically, which one has to imagine in practice as a multi-branched, but starting only from a hot air generator 34 according to Fig. 4, at the end of each air line 32, which of course in the usual way is sheathed with insulation 33, a heat emission device or the housing 18 is connected with its air line connecting piece 19. On the inflow side in front of the hot air generator 34, the fan 9 with high pressure is provided in the fresh air line 35.
  • At least one surface 20 made of at least one heat-resistant molded body 21 is arranged, which is provided with a plurality of air outlet bores 22 and enlarges the inside of the housing with heat transfer surfaces.
  • tiles are particularly suitable, the number of arrangements of which depends on their own size and the size of the housing 18.
  • fastening these molded bodies 21 E.g. the housing could be provided with a correspondingly large grid, in which the molded body 21 can be fixed in a suitable manner.
  • the heat transfer surface enlargements in the form of webs 23, 25 which can be placed on the counter surface 24 of the housing 18 and are provided with recesses 26, 27 so that the hot air flowing in through the air line connecting piece 19 is distributed transversely throughout the housing 18 under the tiles and out of the air outlet bores 22 can flow out, which are expediently provided on the mouth side with a larger diameter than the air inflow side.
  • the webs 23, 25 therefore advantageously form, on the one hand, the support webs for the molded bodies 21 and, on the other hand, also the enlargement of the heat transfer area.
  • the recesses 26, 27 are therefore delimited on the one hand by the counter surface 24 of the housing 18 and on the other hand by the webs 23, 25 which, as shown, can be designed in an arc shape, for example.
  • the molded bodies 21 also have a central bore 28, into which a holding element 29, for example, which can be fixed on the counter surface 24 of the housing 18. in the form of a screw.
  • the molded bodies 21 are not themselves provided with tongue and groove-like peripheral edge profiles which ensure locking against one another and thus to a certain extent also air sealing, the molded bodies 21 can of course also along their peripheral edges 30 to one another and, of course, also against the corresponding opening edge of the housing 18 can be sealed by known means.
  • the preferred embodiment of the molded body, as shown in FIG. 6, is again illustrated in a more clearly spatially illustrated manner in FIG. 7, which also makes it clearer that each molded body 21 can be charged with hot air from the rear, even if several such shaped bodies are joined together in a surface 20 of the housing 18, as is illustrated, for example, in FIG. 8.
  • two surfaces of the housing 18 running parallel to one another are equipped with shaped bodies 21 and, for example, braced against an intermediate wall 24 ′ provided with through openings (not shown) in the sense of FIG. 6.
  • the heat emission device could, for example, also be installed directly in a wall and serve as a radiator for two rooms.
  • the heat dissipation device could of course also be designed in the sense of a cubic body, it being possible for all surfaces, with the exception of the base surface, to be equipped with shaped bodies 21.
  • the device in the sense of FIG. 6 can expediently be provided in the region of its air line connecting piece 19 with a temperature-controlled supply air control flap 31, which is controlled by a room temperature sensor.
  • the fresh air supply can of course also be regulated accordingly in the entire system and overall the hot air generator 34 as a function of the respective heat requirement.
  • the moldings 21 or tiles can of course have different shapes than those shown.
  • the air outlet bores 22 have diameters of approximately 5-8 mm and each molded body 21 can be provided with, for example, up to fifteen openings.
  • a maximum diameter of 50 mm is sufficient in view of the intended high pressure.
  • the heating of the air in the hot air generator 34 can be up to 250 ° C. After the heat has been given off to the shaped bodies 21 inside the housing 18, the surface of which cannot be tiled, the air then flows out of the air outlet bores 22 at approximately 100 ° C.
  • the described embodiments of the heat emitting devices according to FIGS. 5-9 are of course particularly suitable for living rooms. If high spaces, such as workshops, halls or the like, are to be heated with the system described, the heat emission device can advantageously be designed much more simply and specifically in the sense of FIG. 10, i.e. as a tube 36 with corresponding air outlet bores 22.
  • Such a pipe 36 which is installed in a room height of approximately 4 m and is charged with temperatures of 300 ° C., achieves an output of 4000 watts per m 2 of heating surface.
  • it does not now require a large amount of air, but it is sufficient, for example, to provide an air outlet bore of 15 mm diameter for an air volume of 12 m 3 / h per 0.25 m 2 of heating surface corresponds to a heating power of 1 KW.
  • This small outlet means that on the one hand a sufficient flow of hot air can flow into the tube, but on the other hand, as with the tiles, the hot air is expelled from the lefthand holes.
  • These openings are expediently arranged facing downwards. So that the heat radiation specifically heats the floor and the side walls, it is expedient to surround the tube 36 with an insulating material holding shell 37 and to arrange a sheet metal jacket 38 above it, which prevents damage to the insulation.
