Definitions

  • the present invention concerns thermohydraulic or thermoregulation systems with heat transfer fluid, and in particular it concerns thermal regulation groups, also called circulation groups, used to control the distribution of the heat transfer fluid in multi-storey or multi-zone structures.
  • a circulation group typically has one end connected to a manifold, and the other end directed towards a utility.
  • the present invention relates to a distribution manifold for one or more circulation groups in a thermoregulation system with heat transfer fluid.
  • This system comprises at least one primary hydraulic circuit connected to at least one heat source and at least one secondary hydraulic circuit connected to at least one utility.
  • the manifold comprises two watertight chambers for the collection of the heat transfer fluid, of which a delivery chamber for the collection of the heat transfer fluid being delivered from the primary circuit and a return chamber for the collection of the heat transfer fluid returning to the primary circuit.
  • the manifold further comprises a plurality of connectors configured to connect the delivery and return branches of said primary circuit respectively to the delivery chamber and to the return chamber and the delivery and return branches of said secondary circuits respectively to the delivery chamber and to the return chamber by means of said circulation groups.
  • thermohydraulic systems comprising circulation groups.
  • the manifold must be manufactured in a pre-established configuration, which cannot be modified in any way during installation depending on the contingent needs of the installer. This may also require significant structural changes to the system or installation area in the event that, for any reason, the pre-established configuration no longer meets the contingent installation needs.
  • Aim of the present invention is to overcome the aforementioned drawbacks of the collectors known to the state of the art and to realize a manifold with reduced costs, easily adaptable to different manufacturing and installation needs and not subject to problems of release of matter deriving from corrosion inside the system.
  • the present invention achieves the above aims with a manifold as described at the outset, which further comprises a plurality of modular elements which can be assembled together by fixing means.
  • the delivery and return chambers are thus formed by the set of cavities of the individual modular elements that are contiguous to each other.
  • the manifold comprises two terminal elements which can be fixed respectively to two said modular end elements, under assembled condition of the modular elements, said terminal elements being adapted to close said chambers.
  • At least one terminal element is provided with two connectors of connection respectively to the delivery chamber and to the return chamber.
  • At least one gasket is interposed between two contiguous modular elements or between a modular end element and a terminal element.
  • the fixing means allow to hold the components of the manifold bound together in a watertight manner, correctly creating the delivery and return watertight chambers, avoiding leaks of heat transfer fluid and allowing the operation of the system.
  • each modular element is provided with stiffening ribs.
  • This feature is particularly advantageous in combination with the moulding technique of the technopolymer, because it can already be envisaged in the moulds and allows to increase the mechanical performance of the technopolymer.
  • each connector may alternatively comprise a connecting shank for an open configuration or a cap for a closed configuration.
  • the figures illustrate a preferred embodiment example of the distribution manifold for circulation groups in a thermoregulation system with heat transfer fluid according to the present invention.
  • the system comprises a primary hydraulic circuit connected to a heat source, such as a boiler or a heat pump, and a plurality of secondary hydraulic circuits connected to multiple utilities, such as a radiant floor, a heating system, different areas of the building, and/or further similar utilities.
  • a heat source such as a boiler or a heat pump
  • a plurality of secondary hydraulic circuits connected to multiple utilities, such as a radiant floor, a heating system, different areas of the building, and/or further similar utilities.
  • the manifold comprises two watertight chambers 1 for the collection of the heat transfer fluid, of which a delivery chamber 10 and a return chamber 11, and a plurality of connectors 2 configured to connect the delivery and return branches of the primary circuit respectively to the delivery chamber 10 and to the return chamber 11 and the delivery and return branches of the secondary circuits respectively to the delivery chamber 10 and to the return chamber 11 by means of the circulation groups.
  • the modular element 3 is substantially symmetrical along a plane passing through the intermediate wall 32, if the presence of the conduit 22 is omitted.
  • each connection face 31 of the modular element 3 is symmetrical with respect to the axis passing through the intermediate wall 32.
  • two modular elements 3 can be assembled together by connecting the first cavity 33 of the first modular element 3 with the second cavity 34 of the second modular element 3 and the second cavity 34 of the first modular element 3 with the first cavity 33 of the second modular element 3, as can be seen in detail in figure 3 .
  • modular elements 3 of two types a first type being provided with cavities 33 and 34 open on both connection faces 31 exactly as illustrated in figure 1 and a second type with cavities 33 and 34 open only on one connection face 31 and closed on the opposite face, i.e. substantially already incorporating in one piece a terminal element 5.
  • Figure 2 also illustrates said gasket 6 which is interposed between two contiguous modular elements 3 or between a modular end element 3 and a terminal element 5.
  • This gasket 6 fits in both seats 36 of the connection faces 31 of the two contiguous modular elements 3.
  • the connection face of terminal element 5 is provided with a corresponding seat for gasket 6.
  • the seat 36 on a first connection face 31 is constituted by a groove while the seat 36 on the opposite connection face 31 is constituted by a relief insertable into a corresponding groove.
  • Each connector 2 may alternatively comprise a connecting shank 23 for an open configuration, as in the case illustrated in the figure of the upper connectors and of the lateral lower connectors, or a cap 24 for a closed configuration, as in the case illustrated in the figure of the central lower connectors and of the connectors of the terminal elements 5.
  • Each connector 2 comprises a ring nut 25 for retaining the shank 23 or the cap 24.
  • the ring nut 25 is in red for the connectors 2 connected to the delivery chamber 10 and in blue for the connectors 2 connected to the return chamber 11. The configuration illustrated in the figure can therefore be advantageously varied with ease to meet the needs of the system.
  • the modular elements 3 and the terminal elements 5 are preferably made of technopolymer. However, other materials may be used, for example metals such as aluminium.
  • the shanks 23 are preferably made of brass.
  • the manifold is provided with an insulating cover 7, consisting of lateral elements 70, adapted to overlap the modular elements 3, and terminal elements 71 adapted to overlap the terminal elements 5.
  • the lateral elements 70 are advantageously of a size corresponding to two modular elements 3 and can be concatenated with each other depending on the overall dimensions chosen for the manifold.
  • the material of the insulating cover 7 can be of any type known to the person skilled in the art, preferably it is expanded polypropylene.
  • Figure 3 shows in section the manifold in an assembled condition and allows to notice the configuration of the delivery 10 and return 11 chambers in relation to the modular elements 3.
  • connection faces 31 of the modular element 3 ensures that two contiguous modular elements 3 can be assembled together by connecting the first cavity 33 of the first modular element 3 with the second cavity 34 of the second modular element 3 and the second cavity 34 of the first modular element 3 with the first cavity 33 of the second modular element 3.
  • the manifold is therefore built by juxtaposing one another along an assembly axis a plurality of modular elements 3, wherein each modular element 3 is tilted at 180° along the assembly axis with respect to the contiguous modular element 3.
  • Both the delivery chamber 10 and the return chamber 11 are therefore constituted by an alternating sequence of first cavities 33 and second cavities 34 of the modular elements, and terminal elements 5 are closed.
  • the primary connectors 2' adapted to connect the manifold to the primary circuit, are provided below.
  • the primary delivery connector 2' adapted to connect the delivery branch of the primary circuit to the delivery chamber 10 is illustrated on the right and the primary return connector 2' adapted to connect the return branch of the primary circuit to the return chamber 11 is illustrated on the left.
  • These connectors 2 are open since shanks 23 are provided, while the two central primary connectors 2' are closed by the caps 24.
  • the secondary connectors 2 adapted to connect the manifold to the secondary circuits by means of the circulation groups, are provided above.
  • the secondary delivery connectors 2" are adapted to connect the delivery branch of the secondary circuits to the delivery chamber 10 and the secondary return connectors 2" are adapted to connect the return branch of the secondary circuits to the return chamber 11.
  • Figure 4 illustrates a sectional view of the manifold in assembled condition adapted to illustrate in detail the fixing means 4.
  • the fixing means are of a type known to the person skilled in the art and comprise metal pins insertable into the fixing seats 40 and adapted to engage on one side in a pawl provided with a threaded hole and on the other with a closing element activatable by means of a screwdriver.
