Definitions

  • the invention relates to a pipe distributor with a hydraulic decoupler according to the preamble of claim 1.
  • hydraulic decouplers are used to hydraulically decouple the primary-side liquid circuit and the secondary-side liquid circuit, which are also referred to as heat flow exchangers or hydraulic switches.
  • Known hydraulic decouplers consist of a housing which encloses a decoupling space on which the connections for the primary circuit and the secondary circuit are provided on opposite sides. The two flow connections are aligned, as are the two return connections.
  • the invention has for its object to provide a pipe distributor with hydraulic decoupler for heating systems, cooling systems or the like, which takes up as little space as possible and requires as little assembly effort.
  • the hydraulic decoupler is integrated in the form of a decoupling space in the pipe distributor, whereby connecting lines and connecting pieces to the flow chamber and the return chamber of the pipe distributor can be omitted.
  • the hydraulic decoupler is very simple and space-saving.
  • the integration in the pipe distributor also makes thermal insulation of the decoupler extremely simple, since the conventional insulating shells, as are known for the insulation of pipe distributors, can be used for this. Connecting lines which extend between the decoupler and the pipe distributor are omitted in the embodiment according to the invention, so that pipe insulation which is otherwise necessary for this is also no longer required.
  • the pipe distributor consists of an elongated housing, which is divided into a flow chamber and a return chamber by an internal partition.
  • a cutout in the partition a rectangular, round or other shaped cutout being provided for this purpose.
  • the recess can also be formed in that the partition ends at a distance from one of the housing end walls.
  • the partition can have a flat or wavy or other shape.
  • the return chamber and the flow chamber of the pipe distributor can, however, also be designed in the form of parallel pipes which open into a common decoupling space formed on the end face thereof.
  • suitable swirling elements such as baffles or baffles, can be provided at this point. Following the swirling elements, a homogeneous flow is obtained which enables a more precise determination of the temperature of the medium flowing into the flow chamber.
  • a further development of the invention provides that the flow connection of the primary circuit has a pipe section projecting inwards into the decoupling space. This measure also serves to improve the mixing of the return flow from the return chamber with the flow stream which is fed into the decoupling chamber.
  • the return connection of the primary circuit can be arranged in a section of the return chamber which adjoins the decoupling space, as a result of which the decoupling space is partially extended into the return chamber.
  • the distance between the flow connection and the return connection of the primary circuit is increased, which can be expedient in the case of small pipe distributor sizes.
  • the flow connection and the return connection of the primary circuit can be aligned with pipe distributor connections on one side of the pipe distributor housing. To this In this way a clear cable routing is obtained, one of the connections of the hydraulic decoupler being led through one of the two chambers of the pipe distributor.
  • the pipe distributor in which the hydraulic decoupler is integrated in the form of a decoupling space formed in the distributor housing, has great advantages over conventional hydraulic decouplers, which can be seen in particular in the simple construction, the small space requirement and the extremely simple assembly. Other advantages, such as simplification of the thermal insulation and various options for attaching the decoupler connections, can also be mentioned here.
  • the pipe distributor 1 shown in FIG. 1 with an integrated hydraulic decoupler 2 is part of a heating system which comprises two heating boilers 3, 4 on the primary side and two heating circuits 5, 6 on the secondary side.
  • the pipe distributor 1 is connected via connecting pieces 7 to 12 to supply lines VL and return lines RL of the primary and secondary circuits.
  • the pipe distributor 1 has an elongated housing with a square or rectangular cross section, which, apart from in the area of the hydraulic decoupler 2, is divided by a horizontal partition 13 into a flow chamber 14 and a return chamber 15 inside.
  • the partition 13 ends at a distance from the left front housing wall 16, so that a recess 17 is formed which forms a transition from the return chamber 15 to the flow chamber 14.
  • this transition area which is formed by the housing wall 16 and the adjacent end walls 18 of the pipe distributor 1, there is the decoupling chamber 19 of the hydraulic decoupler 2.
  • This decoupling chamber 19 is completely open to the flow chamber 14 and the return chamber 15, so that the return flow 20 in required dimensions can flow through the recess 17 into the flow chamber 14.
  • the return flow 24 which is returned to the primary circuit via the return connection 23, takes up a corresponding proportion of the return flow 20 as flow portions of the flow flow 22 reach the flow chamber 14.
  • hydraulic decoupler 2 By using a hydraulic decoupler 2 between the flow chamber 14 and the return chamber 15 of the secondary circuit, hydraulic decoupling between the primary circuit and the secondary circuit is achieved.
  • the hydraulic decoupler 2 acts simultaneously as a heat flow exchanger between the heat flow Primary circuit and the heat flow of the secondary circuit.
  • the amount of circulating water in the heat generators of the primary circuit is independent of the amount of circulating water in the secondary circuit, where the heat consumers are located.
  • Heat generators that are not in operation for example boilers, thermal baths or the like, can be shut off hydraulically in order not to have to operate the primary circuit with an unnecessarily large amount of water.
  • the return temperature can be adjusted for each energy source in order to create optimal operating conditions.
  • FIG. 2 shows section AA, which in particular shows the recess 17 above and below which the decoupling space 19 of the hydraulic decoupler 2 is located.
  • FIG. 3 shows a pipe distributor 1 in which the flow connection 21 has a pipe section 25 projecting into the decoupling space 19.
  • the return connection 23 of the hydraulic decoupler 2 is guided through the flow chamber 14 to an opening 26 in the partition wall 13, as is also provided for the connecting pieces 10, 12 (FIG. 1) provided for the return lines RL of the secondary circuit.
  • the decoupling space 19 extends into the area under the opening 26 and thus slightly into the area of the return chamber 15
  • an upward swirling element 28 which can be designed as a baffle plate or the like, is arranged at the end 27 of the partition 13, which delimits the recess 17.
  • an upward swirling element 28 which can be designed as a baffle plate or the like, is arranged at the end 27 of the partition 13, which delimits the recess 17.
  • the connections to the pipe manifold are shown only schematically.
  • the pipe distributor 1 of FIG. 5 consists of an upper pipe 29, which forms the flow chamber 14, and a lower pipe 30, which forms the return chamber 15, both pipes 29, 30 opening into a decoupling space 19 of the integrated hydraulic decoupler 2 on the left side.
  • pipe distributor with hydraulic decoupler can be used not only in heating systems between the primary and secondary circuits, but also in cooling systems and other systems for decoupling the primary-side and secondary-side liquid circuits.
