Definitions

  • the present invention relates to a system for distributing fluid, the system comprising a heating distributor and a flexible fluid connector configured to provide a fluid connection between the heating distributor and a pressure maintenance system and/or a degassing device.
  • a heating or cooling installation in a building is often assembled from various components, which together form a hydronic system, from heat or cold generation to the delivery thereof.
  • distributors are used. Such a distributor is actually a hub of all functions in a hydronic installation.
  • FIG. 1 An example of such a heating distributor is shown in European patent application EP3228943A1 disclosing the features of the preamble of claim 1.
  • This is a heating distributor of the so called sinus-type.
  • the sinus definition refers to a sinus shaped wall inside a housing separating two inner spaces. A tube extends into one of the inner spaces of the housing.
  • Possible treatments are for example degassing or pressure maintenance. After treatment the treated water flows back into the same inner space of the housing via the tube.
  • the tube is intended to prevent treated fluid returning into the inner space via the tube from immediately exiting the inner space towards the treatment device. This could lead to undesirable recirculation of already treated fluid.
  • a disadvantage of the tube is that it is difficult to install in tight spaces. Inserting the tube into the inner space requires at least a distance to the side of the housing which is equal to the length of the tube. So a maximum length of the tube may be limited by the tight space.
  • the invention is defined in claim 1 and makes use of a flexible fluid connector configured to provide a fluid connection between a heating distributor on the one hand, and a pressure maintenance system and/or a degassing device on the other hand, the flexible fluid connector in an embodiment further comprising
  • the flexible fluid connector due to the flexible elongate tube the flexible fluid connector is easier to install.
  • the heating distributor to which the flexible fluid connector is to be connected is located in a tight space
  • the flexible elongate tube can be bended or flexed when inserting into the inner space of the heating distributor. This allows the flexible fluid connector to be installed in the tight space, while maintaining a desired maximum length of the flexible elongate tube.
  • the flexible fluid connector is that due to the flexible elongate tube the tube can extend further into the inner space of the heating distributor, in particular when the heating distributor is of the sinus type.
  • the extension of a straight and rigid elongate tube into the inner space of the heating distributor is limited by the sinus shaped wall.
  • the flexible elongate tube can move past the apex of the sinus shaped wall.
  • Another advantage of the flexible fluid connector is that it can be transported efficiently, because the flexible elongate tube can be rolled up.
  • the first through passage is provided at a distance from the second through passage.
  • a first axis of the first connector is provided substantially parallel to a second axis of the second connector.
  • the first and second tubular wall are arranged coaxially, the second through passage being provided inside the first through passage, the first through passage having an annular cross-section.
  • a first axis of the first connector is provided at an angle relative to a second axis of the second connector, in particular between 45 and 90 degrees.
  • the first open end of the flexible elongate tube is connected to the inner end of the second through passage.
  • the flexible elongate tube is flexible along its entire length.
  • the flexible elongate tube is made from rubber.
  • the cap comprises a drain hole extending through the cap.
  • the drain hole allows the fluid in a heating distributor to be drained without having to detach the flexible fluid connector from the heating distributor.
  • the drain hole may advantageously be provided at a lower end of the cap.
  • the invention therefore relates to a system for distributing fluid in a fluid conduit system, the system comprising:
  • the first inner space is provided above the second inner space or vice versa, wherein the first and second inner space and the at least two distributing outlets and the at least two distributing inlets are provided in a single substantially vertical plane.
  • the at least two second distributing pipes extend through the first inner space, or wherein the at least two first distributing pipes extend through the second inner space, when seen in a cross-sectional side view.
  • the first and second inner space are provided in a single housing, wherein the first and second inner space are separated by a sinus-shaped wall.
  • the flexible fluid connector is further connected to the connection opening of the heating distributor via a sealing member.
  • system further comprises a pressure maintenance system and/or degassing device, the pressure maintenance system and/or degassing device being connected to the heating distributor via the flexible fluid connector.
  • the invention further relates to a method for converting a system comprising:
  • the system comprises a heating distributor 2.
  • the heating distributor 2 has at least one first wall 34 which defines a first inner space 35 for accommodating a body of hot fluid 62.
  • the first space has a closed end 66.
  • the at least one first wall 34 defines a cylindrical tube. It is also possible to have four first walls 34 defining a tube with a rectangular cross-section.
  • the heating distributor 2 has at least one second wall 36 defining a second inner space 37 for accommodating a body of cool fluid 63.
  • the at least one second wall 36 also defines a cylindrical tube. Other shapes are also possible.
  • the second inner space 37 is separated from the first inner space 35.
  • An upstream pipe 38 defines a main upstream inlet 39 which is in fluid communication with the first inner space 35.
  • the upstream pipe 38 is connected to the at least one first wall 34 for guiding hot fluid 62 into the first inner space 35.
  • the upstream pipe 38 is configured to be connected to an upstream conduit upstream of the first inner space 35 (not shown).
  • At least two first distributing pipes 41 define at least two distributing outlets 42 which are in fluid communication with the first inner space 35.
  • the at least two first distributing pipes 41 are connected to the at least one first wall 34 for guiding hot fluid 62 out of the first inner space 35.

  • At least two second distributing pipes 44 define at least two distributing inlets 45 in fluid communication with the second inner space 37.
  • the at least two second distributing pipes 44 are connected to the at least one second wall 36 for guiding cool fluid 63 into the second inner space 37.
  • the at least two distributing inlets 45 are configured to be connected to at least two conduits upstream of the second inner space 37 (not shown).
  • a downstream pipe 47 defines a main downstream outlet 48 in fluid communication with the second inner space 37.
  • the downstream pipe 47 is connected to the at least one second wall 36 for guiding cool fluid 63 out of the second inner space 37.
  • the downstream pipe 47 is configured to be connected to a downstream conduit downstream of the second inner space 37 (not shown).
  • An aim of the heating distributor 2 is to guide hot fluid 62 from the main upstream inlet 39 to the at least two distributing outlets 42 and to guide cool, incoming fluid 63 from the at least two distributing inlets 45 to the main downstream outlet 48, as shown in figure 2 .
  • the heating distributor 2 has a connection opening 5 connected to the second inner space 37, i.e. the connection opening 5 is in fluid communication with the second inner space 37.
  • a cap 4 of the flexible fluid connector 1 according to the invention is connected to the second inner space 37 via the connection opening 5, in particular at an outer circumference of the connection opening, e.g. a rim.
  • a flexible elongate tube 21 extends into the second inner space 37 of the heating distributor 2, in particular over a distance 26 which is substantially equal to a length 24 of the flexible elongate tube 21.
  • the flexible fluid connector 1 can be further connected to the connection opening 5 of the heating distributor 2 via a sealing member 60.

  • the flexible fluid connector 1 comprises a cap 4 which is configured to be connected to the connection opening 5 of the heating distributor 2.
  • the cap 4 itself is shown in figures 7 and 8 , in respectively a front view looking at an inner end 20 of the cap 4 and a cross-sectional view.
  • the cap 4 has a first tubular wall 6 defining a first through passage 7.
  • the first through passage 7 allows a fluid to pass through the cap 4 in a first direction 9, in particular from the heating distributor 2 to the pressure maintenance system and/or degassing device.
  • a second tubular wall 10 defines a second through passage 11.
  • the second through passage 11 allows a fluid to pass through the cap 4 in an opposite, second direction 13, in particular from the pressure maintenance system and/or degassing device to the heating distributor 2.
  • the first through passage 7 is provided at a distance 28 from the second through passage 11.
  • the flexible fluid connector 1 has a first connector 14 provided at an outer end 15 of the first tubular wall 6.
  • the first connector 14 is configured to be connected to an inlet of the pressure maintenance system and/or degassing device (not shown).
  • the first connector 14 is provided with outer thread 57.

  • the length 24 is more than ten times the width 25.
  • the first open end 22 of the flexible elongate tube 21 is connected to the inner connector 19 of the first or second tubular wall 10, for example by shoving it over the inner connector 19.
  • a further connector 58 58 may be provided to further affix the flexible elongate tube 21 to the inner connector 19.

  • the heating distributor 2 in figures 9 and 10 is identical to the heating distributor 2 as shown in the previous figures.
  • the flexible fluid connector 1 has most features in common with the first embodiment.
  • the first and second tubular wall 10 are arranged coaxially.
  • the second through passage 11 is provided inside the first through passage 7, and the first through passage 7 has an annular cross-section 31.
  • Another cross-sectional shape may also be possible, like rectangular or square for example.
  • the first open end 22 of the flexible elongate tube 21 is connected to the inner end 20 of the second through passage 11.
  • a first axis 29 of the first connector 14 is provided at an angle relative to a second axis 30 of the second connector 17, in particular between 45 and 90 degrees.
  • Fig. 12 (The PRIOR ART) figure and figure 13 show in cross-section a section of a heating distributor 2, wherein the first and second inner space 37 are provided in a single housing 52. Within the single housing 52 the first and second inner space 37 are separated by a sinus-shaped wall.
  • Fig. 12 (The PRIOR ART) figure shows a rigid elongate tube 55 extending into the second inner space 37 of the heating distributor 2.
  • the extension of the rigid elongate tube 55 into said second inner space 37 is however limited due to an apex 61 of the sinus shaped wall 53.
  • Figure 13 shows the flexible fluid connector 1 with the flexible elongate tube 21 extending into the second inner space 37 of the heating distributor 2.
  • An advantage of the flexible elongate tube 21 is that it is able to bend and compress so that it can extend beyond the apex 61 of the sinus shaped wall 53.
  • the invention further relates to a method for converting a system 100 comprising the heating distributor 2 with the single housing 52 and the sinus shaped wall 53, wherein the rigid fluid connector 67 with a rigid elongate tube 55 is provided in the second inner space 37.
  • the above mentioned system is converted to a system 100 comprising said heating distributor 2 and a flexible fluid connector 1 according to the invention.
  • the cap 4 of the flexible fluid connector 1 is connected to the second inner space 37 via the connection opening 5, wherein the flexible elongate tube 21 extends into the second inner space 37.
  • the method comprises the steps of:
  • the method may further comprise installing the sealing member 60, thereby further affixing the cap 4 to the connection opening 5.
  • the method may also comprise bending the flexible elongate tube 21 prior to and during the insertion of said flexible elongate tube 21 into the second inner space 37 via the connection opening 5, as shown in figures 3 and 4 .
  • An advantage of said bending is that the flexible fluid connector 1 can be installed into already installed heating distributors which are located in a tight space.
  • Figures 2 , 9 and 10 show different modes of operation of the heating distributor 2 and the flexible fluid connector 1, namely a normal operation mode and a recirculation mode.
  • Figures 2 and 9 show a normal operation mode, wherein there is substantially no recirculation of the body of fluid in the second inner space 37, i.e. after the fluid exits and treated fluid returns to the second inner space 37 through via the flexible fluid connector 1, the treated fluid leaves the second inner space 37 via the downstream pipe 47 and does not exit the second inner space 37 again via the flexible fluid connector 1.
  • Hot fluid 62 enters the first inner space 35 via the main upstream inlet 39 and is subsequently distributed through a conduit system (not shown) downstream the first inner space 35 via the two distributing outlets 42.
  • the hot fluid 62 cools down through the conduit system and flows into the second inner space 37 via the two distributing inlets 45. So a cool, incoming fluid with a temperature lower than the hot fluid 62 thus enters the second space.
  • part of the cool fluid 63 in the second inner space 37 exits the second inner space 37 via the first through passage 7 of the flexible fluid connector 1.
  • Said cool fluid 63 is treated in for example a pressure maintenance system and/or degassing device and returns after treatment in the second inner space 37 via the second through passage 11 and the flexible elongate tube 21.
  • the cool fluid 63 then flows via the main downstream outlet 48 to a downstream conduit (not shown) downstream of the second inner space 37 and of the heating distributor 2.
  • An advantage of the flexible elongate tube 21 is that due to its relatively long length 24 a risk of recirculating the same part of cool fluid 63 through the pressure maintenance system and/or degassing device is reduced. This means that there is substantially always fresh fluid for treatment through the pressure maintenance system and/or degassing device.
  • Figure 10 shows the recirculation mode, wherein there is no flow of fluid through the first inner space 35 and the conduit system downstream the first inner space 35. The no flow is indicated by the crosses 65. Therefore there is also no influx of fluid into the second inner space 37 via the two distributing inlets 45.
  • the body of fluid in the second inner space 37 will recirculate through the pressure maintenance system and/or degassing device via the flexible fluid connector 1.
