Definitions

  • the present invention relates to a heating arrangement for buildings.
  • Such heating arrangements have long been known in the art.
  • a circulating liquid such as water
  • a burner In this combustion process hot exhaust gases, which are usually passed through a flue pipe or a fireplace to the outside. These exhaust gases still have a considerable amount of heat, which thus reaches the outside unused.
  • Various devices are known from the prior art to use the heat of these exhaust gases.
  • a device for heat recovery from flue gases which is arranged in the train of a chimney, said device having a liquid-flowed heat exchanger.
  • this device is very difficult to access, for example, in the case of repairs and difficult to install.
  • a heat exchanger system for any heat generator is known.
  • an exhaust pipe is provided with a sheath which leads a liquid heat carrier and is in communication with a heat user.
  • This device may also include a temperature sensor and a temperature-controlled valve which causes air to be forced into the heat circuit when the liquid in the jacket overheats.
  • this device requires an active element, such as a compressor, and thus an electrically operated element.
  • this system for example, in the event of a power failure is not able to prevent occurring overheating of the liquid to be heated.
  • the present invention is therefore an object of the invention to provide a heating arrangement available that avoids overheating of the heating water even with different malfunction.
  • the heating arrangement according to the invention for buildings has a passage tube for discharging a heated gaseous medium. Furthermore, a first flow channel is provided, which is at least partially disposed around the outer circumference of the passage tube and within which a first liquid medium can flow, said first flow channel is at least partially in thermal contact with the passage tube.
  • a second flow channel is provided, which is at least partially disposed around the outer periphery of the passage tube and can flow within a second liquid medium, wherein the first liquid medium and the second liquid medium are separated from each other by the flow channels and the first flow channel and the second flow channel in thermal contact with each other.
  • the said liquids are preferably water, wherein in the first flow channel the heating water flows, which is intended for heat recovery and in the second flow channel at least temporarily, the cooling water can flow.
  • the flow channel can be pipes or the like within which liquid can flow.
  • the channel is formed by different communicating walls, that is, for example, by an outer wall of the passage tube and by an outer wall of another flow channel.
  • a flow channel it is also possible for a flow channel to extend between the passage tube, an outer tube surrounded by the passage tube, and the other flow passage. The thermal contact between the passage tube and the flow channel comes about here in particular through the wall portion of the passage tube, which also limits the flow channel.
  • the first flow channel serves to guide the heating water, that is, the water flowing through this first flow channel is heated by the exhaust gases flowing through the passage pipe.
  • cooling water can be sent through the second flow channel to prevent overheating of the liquid in the first flow channel.
  • the two flow channels are in thermal contact with each other to ensure the best possible heat transfer.
  • the first flow channel is preferably arranged on the pull-through tube such that it is in thermal contact with this pull-through tube.
  • the second flow channel is a tube which is arranged around the outer circumference of the passage tube.
  • the first flow channel is thus formed by the wall or the outer circumference of the passage tube, an outer tube and the second flow channel.
  • first flow channel and the second flow channel are in thermal contact via this wall section.
  • the second flow channel spirally extends around the outer circumference of the passage tube.
  • a particularly favorable heat exchange between the two flow channels is possible.
  • other variants would also be possible insofar as, for example, a variant in which the second flow channel in the longitudinal direction of Passing through the tube along, is bent at one end portion of the passage tube by 180 ° and runs back, this process is continued around the outer circumference of the passage tube.
  • the passage tube has a circular cross section, and particularly preferably the second flow channel is likewise formed with a circular cross section.
  • the first flow channel is formed by intermediate spaces between the individual turns of the second flow channel.
  • the liquid in the first flow channel is also guided spirally around the passage tube, so that in this way a particularly favorable heat exchange both between the two flow channels and between the first flow channel and the passage tube is possible.
  • the flow cross section of the second flow channel is smaller than the flow cross section of the first flow channel. It should be noted that the second flow channel is used only in case of need for cooling the liquid in the first flow channel.
  • an outer tube is provided radially outside the flow channels.
  • the first flow channel can be formed particularly advantageously between the inner wall of this outer tube and the outer wall of the passage tube.
  • a temperature sensor for measuring the temperature of the liquid flowing in the first flow channel.
  • This temperature sensor is used to control the water cycle, which includes the first flow channel.
  • a pump can be activated which drives the water through the flow channel or conveys heated water in the first flow channel into a consumer such as a floor heating system.
  • the device has a temperature sensor.
  • This temperature sensor may also be an electrically operated element, but is preferably a non-electrically operated element, which thus also in de-energized state works.
  • the temperature sensor can likewise be arranged in the first flow channel but also in the second flow channel or at another point, in particular in an upper region of the passage tube.
  • the temperature sensor effects cooling through the second flow channel in response to overheating of the water in the first flow channel. It is thus possible for the tempering sensor to have an expanding liquid which, at a certain limit temperature, causes the second flow channel to be opened and thus cooling to be effected.
  • the expansion of the liquid provided in the temperature sensor can cause a valve to open, which in turn initiates a flow through the second flow channel.
  • this temperature sensor detects too high a temperature, countermeasures or cooling measures can be initiated.
  • this temperature sensor is part of an overheating protection.
  • the second flow channel also has a valve.
  • This valve is particularly preferably coupled to the temperature sensor and may be opened in response to too high a temperature to direct a coolant, in particular cool water, through the second flow channel.
  • a controller which, in response to a signal output by the temperature sensor, controls the valve, which is most preferably a solenoid valve.
  • the controller can also be designed such that cooling takes place until the temperature of the heating water has dropped below a predetermined desired value again.
  • the second flow channel is connected to a liquid feed line.
  • a liquid feed line may be, for example, liquid reservoirs which are provided in the roof of a building, or else a water tap or the like.
  • the liquids are guided in the two flow channels in opposite directions. In this way, a uniform and particularly efficient cooling of the liquid in the first flow channel can be made.
  • the liquid in the first flow channel has the highest temperature at the upper region of the flow channel or the through-tube, because it has been heated here the longest. Conversely, if the cooling liquid is introduced from above, the cooling liquid has a correspondingly lower temperature and thus a particularly efficient cooling is possible.
  • the second flow channel is permanently filled with liquid.
  • the permanent filling has the advantage that overheating of the second flow channel, for example, the wall of the passage tube is prevented.
  • the first flow channel is in communication with a heat reservoir, that is, the introduced into the liquid in the first flow channel heat is further used for the heating of rooms.
  • the passage pipe is particularly preferably an exhaust pipe of a heater.
  • the present invention is further directed to a heating system with a heating arrangement of the type described above.
  • This heating system particularly preferably has a burner.
  • the present invention is further directed to a method for heating rooms, wherein a first liquid flows through a passage pipe, which is traversed by heated air, in a first flow channel and is heated by a thermal contact with the passage tube.
  • a second liquid medium is at least temporarily guided around the passage tube in a second flow channel and this second liquid is used to cool the first liquid.
  • the cooling takes place via a thermal contact between the two flow channels or the respective liquids.
  • FIG. 1 shows a block diagram of a heating system 20.
  • This heating system 20 has a burner 21. The resulting during combustion heated gases pass through a passage tube 2 to the outside along the arrow P1. An arranged above the burner 21 heat exchanger is not shown.
  • the reference numeral 1 refers to the heating device according to the invention in order to use the heat of the heated exhaust gas as well.
  • This heating arrangement is in Fig. 1 also not shown in detail, however, has an inlet 14 and a return 12 for the water to be heated. These feeds and returns can in turn be connected to a heat reservoir, for example, to heat service water.
  • Reference numerals 13 and 15 refer to an inflow and an outflow for the cooling water.
  • Fig. 2 shows a plan view of a heater according to the invention 1. It can be seen that an outer tube 8 is arranged around the passage tube 2. This outer tube 8 is closed at the upper and lower end, so that forms a closed volume between this outer tube and the passage tube 2 apart from the supply and discharge lines. At the in Fig. 2 In the embodiment shown, both the passage tube 2 and the outer tube 8 have a circular cross-section.
  • Reference numeral 6 denotes a second flow channel for a cooling medium, for example for cooling water.
  • the cooling water passes through an inlet 13 into the second flow channel 6 and can flow down from there to a drain 15 Fig. 2 shown embodiment
  • the cooling water from top to bottom is therefore basically independent of pumps or similar facilities.
  • This second flow channel 6 is preferably located both on the passage tube 2 and on the outer tube 8. In this way, between the individual turns 6a or coils of the second flow channel 6, a likewise spiral-shaped intermediate space is formed, which forms the first flow channel 4 with the outer tube and the passage tube 2. Through the first flow channel 4, the water to be heated, starting from the inlet 14 up to the return line 12 is passed.
  • the material of the first flow channel is chosen so that it allows a good heat transfer between the cooling medium in the second flow channel and the liquid in the first flow channel 4.
  • the second flow channel 6 or the tube has a circular cross-section.
  • the second flow channel 6 other cross sections, such as a rectangular cross section or the like. In this way, with similar or essentially the same flow cross section, the contact surfaces to the first flow channel 4 could be increased.
  • the reference character P1 indicates the flow direction of the flue gas through the passage pipe 2.
  • the reference numeral 7 refers to a temperature sensor which measures the temperature of the water to be heated.
  • this temperature sensor 7 is preferred, as in Fig. 2 shown, arranged at the upper end of the passage tube 2. Since the heating water flows from bottom to top, it has its highest temperature at the upper end of the passage tube 2 and thus the temperature sensor is particularly favorable at the upper end of the passage tube 2.
  • the water cycle can be regulated by the first flow channel 4.
  • the reference character L denotes the longitudinal direction of the passage tube 2.
  • the reference numeral 17 refers to a sensor for the safety valve or a temperature sensor. As soon as the temperature sensor 17 registers an excessively high temperature of the heating water, a valve (not shown in detail) is opened, which causes cooling water to flow through the second flow channel 6 from top to bottom.
  • Fig. 3 shows a side view of in Fig. 2 shown heater.
  • the reference numeral 14 shows the inlet for the water to be heated.
  • This inlet 14 has at in Fig. 3
  • a conical tip 14 a in order to bring the water to be heated particularly advantageous in the spaces between two coils or turns 6 a of the second flow channel 6.
  • the outer diameter of the second flow channel 6 and the corresponding tube 6 is in the in Fig. 2 shown embodiment about 12 mm.
  • the distance between two windings 6a lying in the longitudinal direction L of the pull-through tube is correspondingly in a range between 36 and 40 mm.
  • the ratio between the flow cross section of the first flow channel and the flow cross section of the second flow channel is between 2: 1 and 10: 1, preferably between 2.5: 1 and 7: 1, and more preferably between 3: 1 and 5: 1.
  • Fig. 4 shows a plan view from above of the heating device according to the invention. It can be seen that the temperature sensor 7, the temperature sensor 17 for the discharge safety device and the venting tube 19 for the first flow channel 4 are arranged together in an attachment or block 20.
  • the first flow channel 4 is formed by the spaces between the second flow channel and the pipe 6, respectively.
  • the two flow channels in the form of a double tube, which is placed or wound around the passage tube 2.
  • the water to be heated is in direct contact with the passage tube 2, whereby the temperature transition and the heating of the water to be heated is facilitated.
  • Fig. 5 shows that the distance between two helix 6a of the second flow channel 6 and the diameter of the second flow channel 6 at the same time the flow cross-section of the first flow channel 6 is influenced or determined by the distance.
  • the inflow 13 and the outflow 15 of the second flow channel 6 are each located on the same side of the passage pipe 2.
  • the pitch circle Tk denotes the circle on which the respective center points of the second flow channel 6 lie.
  • the heating water is coupled down and moves along the arrows P2, also spirally, upwards.
  • the distances of the two lowest coil can be varied to facilitate the supply of heating water. More specifically, the distance between the last and the penultimate helix can be reduced, thus increasing the distance between the last helix and the bottom plate 24, and thus facilitating the supply of the water to be heated.
  • the cooling water flows within the second flow passage in the direction of the arrow P3.
  • Fig. 6 shows four views of the outer tube 8 with the supply and discharge lines arranged thereon for the cooling water and for the water to be heated.
  • This outer tube has at the upper and lower ends respectively (not shown) openings which surround the passage tube 2. More specifically, the inner periphery of the outer tube 8 can be liquid-tightly connected to the bottom plate 24 of the passage tube 2.
  • the attachment 20 is, as mentioned above, directly fixed to the outer tube 8 and the tip 14a abuts a circular segment-shaped portion 8a of the outer tube 8 at. It can also be provided a double tube, which forms a first and second flow channel. It would also be possible to provide a double tube forming the first and second flow channels. It would also be possible to separately attach a wall between the individual turns of the second flow channel.
