Definitions

  • the invention relates to a supply air and exhaust air adapter for a heater which has at least one input opening for the supply air and at least one output opening for the exhaust air, the supply air and exhaust air adapter having a housing with receptacles for the input opening and the output opening.
  • Supply air and extract air adapters for heaters are required if, for example, a new heater is to be installed or a previous heater is to be replaced and there are fixed connection conditions for the supply air and extract air. There is a difficulty in designing the adapters in such a way that the exhaust air, i.e. the flue gas, is prevented from escaping safely and for a long time.
  • Examples of supply and exhaust air adapters are from the documents NL 1017675 or NL 9100209 known.
  • document NL 1017675 discloses a supply air and exhaust air adapter according to the preamble of claim 1.
  • the supply air and exhaust air adapter according to the invention in which a passage and a branch path are provided within the housing, has the advantage that exhaust air, if it should escape, is discharged back into the system. An uncontrolled escape, for example, into the installation room is avoided.
  • the passageway has an inlet and an outlet, and at least one seal receptacle for a seal at the outlet is provided.
  • the through path and / or the further through path has seal receptacles for seals.
  • the connection remains within the housing and thus further increases security.
  • branch path has an inlet and an outlet and the outlet is connected to the further through path or is identical.
  • the variability increases. This is further increased if at least one second insert is provided which is able to close the outlet of the branch path.
  • the variability is increased again if at least one reducing insert is provided which is capable of reducing the diameter of the passage and / or the further passage.
  • the through path has a diameter of 80 mm
  • the further through path has a diameter of 125 mm
  • the branch path has a diameter of 80 mm. This makes it easy to connect the common supply and exhaust air routes.
  • FIG. 1 a supply air and extract air adapter according to the invention together with the associated inserts
  • Figure 2 a section along line II-II in Figure 1
  • Figures 3 to 5 different application variants
  • Figure 6 a part of a supply air and exhaust air adapter according to the invention with drawn air flow paths.
  • the supply air and exhaust air adapter 10 has a housing 12 with a receptacle 14 for an inlet opening for the inlet air for a heater and a receptacle 16 for an outlet opening for the outlet air of the heater.
  • FIG. 1 possible uses for the supply air and extract air adapter 10 according to the invention are shown.
  • a first insert 20, a second insert 22 and a reducing insert 24 are drawn, but these will only be described later.
  • the passage 26 has an inlet 30 and an outlet 32, the receptacle 16 for the outlet opening for the exhaust air of the heater being located at the inlet 30. At the outlet 32 there is another receptacle 34 to which a further pipe can be connected.
  • a seal 36 is provided, via which the pipe which is then received and can be sealed can be sealed.
  • a receptacle 38 with a seal is likewise provided at the inlet 30 or its receptacle 16.
  • the supply air and extract air adapter 10 is connected via the inlet 30 to a flue gas outlet of a heating device. The flue gas thus flows through the passage 26 from the heater into a further pipe and then into the atmosphere.
  • the further pipe is indicated as a dash-dot line.
  • the passage 26 is arranged in the housing 12 within a further passage 40.
  • the arrangement is such that the Passage 26 is arranged concentrically within the further passageway 40.
  • For fastening webs 42 are provided, which extend from the inside of the further passage 40 to the outside of the passage 26 and connect them.
  • the further passage 40 can be used for the supply air, ie the fresh air supplied to the heater from the outside.
  • receivers 44 for the heater on the one hand and a further pipe on the other are provided on the input and output sides of the further passage 40.
  • the receptacles are equipped with recesses 46 for seals 48, which are partially shown.
  • the supply air is routed via its inlet 41 to its outlet 43. Since the fresh air flows against the exhaust air, the inlet 41 of the further passage 40 is located in the region of the outlet 32 of the passage 32. On the side of the inlet 30, the passage 26 is flush with the further passage 40 and its outlet 43.
  • the through path 26 is shorter than the further through path 40 and therefore remains a bit within the housing 12.
  • This shortening is between 0.3 cm and 3 cm. The purpose of this shortening will be discussed later.
  • the branch path 28 has an inlet 50 and an outlet 52.
  • the receptacle 14 for the inlet opening for the supply air of the heater is molded onto the outlet 52. That is, in the exemplary embodiment, the outlet 52 is identical to an outlet 43 of the further passage 40.
  • the branching path 28 branches off from the further through path 40 or opens into this, if one considers this in the direction of flow of the supply air.
  • the branching path 28 In the area of the inlet 50, the branching path 28 has a receptacle 54 which can receive a seal 56 and into which a further pipe can be inserted.
  • the supply air can thus be supplied to a heater from outside either through branch path 28 or through further passage 40.
  • the housing 12 has a closable opening 57, which is connected to the through-way 26 via a tube (not shown). This allows measurements of the exhaust air to be carried out during maintenance work.
  • FIG 3 An application variant is shown in which the supply air and exhaust air adapter 10 changes the supply air or the exhaust air from the concentric air duct at the heater outlet to a parallel air duct.
  • an insert 20 is provided which is capable of covering the inlet 41 of the further passage 40.
  • the first insert 20 has an annular cover 58, the outer diameter 60 of which is larger than the diameter 62 of the clear width of the further passage 40.
  • a piece of pipe 64 is attached to the cover 58, the outer diameter of which corresponds to the diameter 62 of the further passage 40.
  • the first insert 20 can thus be inserted with the pipe section 64 into the further passage 40.
  • the first insert 20 is sealed to the outside via the seals 48.
  • the annular cover 58 has an inner opening 66, the clear width of which corresponds to the inner diameter 68 of the passage 26.
  • the supply air is then passed through the inlet 50 of the branch path 28.
  • the inner diameter 70 of the inlet 50 corresponds to a standard dimension and is 80 mm in the exemplary embodiment.
  • the diameter 62 of the further passage 40 and the diameter 68 of the passage 26 correspond to standard dimensions.
  • the diameter 62 has a size of 125 mm
  • the inner diameter has a size of 80 mm.
  • FIG. 6 One according to the embodiment Figure 3 corresponding air flow is in Figure 6 shown.
  • the first insert 20 can be seen, which sits in the further passage 40, is sealed by the seal 48 and closes the further passage 40 with the cover 58.
  • a further pipe 72 is seated in the passage 26 and is sealed by the seal 36.
  • the exhaust air follows the arrow 74 in the normal case, while the supply air follows the arrows 76. If the seal 36 leaks and the exhaust air escapes along the arrow 78, it is taken along by the supply air along the arrows 76 (Venturi effect) and fed back into the heater. This ensures that no exhaust air can escape from this area into the heater's installation room.
  • this effect is achieved in that - as already described - the passage 26 remains a bit behind the other passage 40.
  • this distance 81 is of the order of 2 cm.
  • the inner opening 66 has an additional seal 80 in the exemplary embodiment.
  • the inlet 50 of the branch path 28 is closed with the second insert 22.
  • the insert 22 has a circular cover 82, the outer diameter of which is larger than the inner diameter 70 of the inlet 50.
  • a pipe section 84 adjoins the cover 82, the diameter of which corresponds to the diameter 70. If the second insert 22 is inserted, the seal 56 seals the inlet 50 on the pipe section 84.
  • the supply air is consequently supplied via the further passage 40.
  • a reducing insert 24 is introduced into the further passage 26.
  • the reducing insert 24 has an annular cover 86, the outer diameter of which is larger than the diameter 62 of the further passage 40.
  • a piece of pipe 88 is connected to the cover 86, the diameter of which corresponds to the diameter 62 of the further passage 40 and that via the seal 48 is sealed. Since the branch path 28 is closed by the second insert 22, the tube piece 88 of the reducing insert 24 can be longer than the tube piece 64 of the first insert 20.
  • the annular cover 86 has an inner opening 90 which has an inner diameter that is reduced compared to the diameter 62 92 owns. In the area of the inner opening 90, a seal 94 is attached, which is able to seal an inserted, further pipe.
  • a reducing tube 96 is arranged in the reducing insert 24, the outer diameter of which corresponds to the inner diameter 68 of the passage 26. At its upper end, the inner diameter 98 is reduced compared to the inner diameter 68. If the reducing tube 96 is inserted into the passage 26, the seal 36 seals the passage. In order to also seal a further pipe that is inserted into the reducing pipe 96, the outlet opening 100 has a seal 102.
  • the reducing pipe 96 can be designed as a loose, separate component which, when in use, is inserted separately into the passage 26. In the exemplary embodiment, however, it is fastened to the tube piece 88 via webs 104. The has the advantage that after installation of the supply air and exhaust air adapter 10 and connection of the corresponding further pipes, it is ensured that the reducing pipe 96 is actually installed.
  • the concentrically routed connection of the heater to a concentrically routed supply air and exhaust air duct is reduced to predetermined sizes that occur in the house installation.
  • the diameter 92 has a size of 100 mm
  • the diameter 98 has a size of 60 mm.
  • the inlet 50 of the branch path 28 is closed again with the second insert 22.
  • Both the passage 26 and the further passage 40 are open to the outside, so that further pipes with an outer diameter corresponding to the inner diameter 68 or corresponding to the diameter 62 of the further passage 40 can be used.
  • the diameter 62 of the further passage is 125 mm and the diameter 68 of the passage 26 is 80 mm.
