Definitions

  • the present invention relates to a distribution manifold for forced circulation heating system comprising a first set of connections apt to associate it with delivery and recirculation lines of the first part of the heating system which presents radiant ducts built in walls and a second set of connections apt to associate it with delivery and recirculation lines of the second part of the heating system which presents external radiators.
  • heating systems in particular heating systems for household users, consists of forced circulation heating systems with heating elements built in the floor in each household system.
  • hot water from the boiler reaches a distribution manifold, which transfers it to a delivery duct where a centrifugal pump ensures the forced circulation towards the household system.
  • the heating elements consist mainly of built-in radiant elements, i.e. pipe coils buried in the floor or also in the walls.
  • a recirculation duct takes the water from the heating elements to a mixing valve, which is controlled by special temperature sensors and mixes the hot delivery water with the cold recirculation water.
  • a further object of the present invention is to provide a distribution manifold for forced circulation heating system, which is coplanar.
  • a further object of the present invention is to provide a distribution manifold for forced circulation heating system, which is stronger and more reliable.
  • Figure 1 shows a draft diagram of a forced circulation heating system in which reference number 1 indicates a boiler that transfers hot water to a distribution manifold block 2 by means of a boiler delivery line 18.
  • the distribution manifold block 2 returns to the boiler 1 the water used for heating by means of a boiler recirculation line 19.
  • the above-mentioned distribution manifold block 2 is connected to a radiant system built in the floor 3, by means of a delivery line of the floor system 4, on which the mixing unit 5 is placed, followed by the pump 6.
  • the ducts 7 branch off from the delivery line of the floor system 4 towards their pipe coils 8 allocated in different household systems.
  • the recirculation ducts 9 join a recirculation line of the floor system 10, which returns to the distribution manifold block 2 to join the boiler recirculation line 19.
  • the recirculation line of the floor system 10 also presents an offtake 20 that feeds mixing unit 5.
  • the above-mentioned mixing unit 5 corresponds mainly a three-way valve driven by an actuator controlled by a control unit 11, which receives information on the temperature by the sensors that are not indicated here and is programmed to choke appropriately the flows received from the recirculation line of the floor system 10 and from the distribution manifold block 2.
  • the distribution manifold block 2 is connected also to a second system, which consists of external radiators 12, comprising a delivery line 16 of the external radiators, from which ducts 13 branch off towards external radiators 14 placed in household systems.
  • Return ducts 15 join a recirculation line 17 of the external radiators, which joins the recirculation line of the boiler 19.
  • Figure 2 shows a forced circulation heating system according to the present invention.
  • the distribution manifold block 2 comprising a distribution manifold element 22 obtained as a monobloc brass casting.
  • the above-mentioned distribution manifold element 22 comprises a boiler delivery connector 23 and a boiler return connector 24 apt to house corresponding on-off ball valves 25, which make the distribution manifold element 22 communicate with the boiler 1, not represented here.
  • Connector 23 transfers the hot water on one side to the first branch corresponding to the radiant system built in the floor 3 and on the other side to a second branch corresponding to the second system made of external radiators 12; said connector 23 feeds an output connector 27, which feeds a delivery and a flow rate adjustment duct 28, obtained as a monobloc brass casting, as well as for the second branch to a duct for external radiators 26.
  • the delivery and flow rate adjustment duct 28 which is used to adjust the hydraulic charge between the radiant system built in the floor 3 and the second system with external radiators 12, is completed with a fast coupling 29 on the monobloc of the distribution manifold element 22, which allows to connect a bypass valve 30 that is used to adjust manually the flow rate on the second system of the external radiators 12. Downstream of this bypass valve 30, a thermometer 31 is placed in a special housing provided in the monobloc of the delivery and flow rate adjustment duct 28. As an alternative, a probe can be provided and remote controlled from the control unit 11 of figure 1.
  • the delivery and flow rate adjustment duct 28 ends with two ways, represented by a delivery connector 32 and a vent connector 33, apt to house a nonreturn valve 34, whose function is to prevent mixing with the cold recirculating water, together with a vent connector 35 of the distribution manifold element 22, on which this nonreturn valve 34 is fixed by means of a ring nut 36.
  • the distribution manifold 22 presents also a common return duct 38 that flows in the boiler return connector 24, which, by means of a special connecting branch 37 is joint to the vent connector 35 and to a recirculation connection block 42 of the floor system, which is obtained as a monobloc brass casting.
  • the above-mentioned recirculation connection block 42 of the floor system allows the inflow of the water coming from the recirculation line of the floor system 10; this water must be transferred towards the boiler recirculation line 19, as well as towards the mixing unit 5, incorporating the offtake 20 represented in figure 1.
  • the nonreturn valve 34 housed in the vent connector 35 and in the vent connector 33 is used to prevent the recirculation water from flowing back without control in the delivery and flow rate adjustment duct 28.
  • the duct for external radiators 26 and the common return duct 38 are placed in parallel and connected by means of the inlet openings 39.
  • the connectors 40 alternate with the connectors 41, which are connected to the return ducts 15. Therefore, the common return duct 38 represents the terminal part of the recirculation line of the external radiators 17 of figure 1, as well as, by means of the connecting branch 37, of the recirculation line of the floor system 10.
  • the special housing provided in the monobloc houses a nonreturn valve 43 in order to prevent high temperature flows deriving in particular from the delivery and flow rate adjustment duct 28 as well as form the duct of the external radiators 26 from entering in the recirculation line of the floor system 10 or in the delivery line of the floor system 4, apart from pump 6, where temperature sensors are placed as described later.

  • the other end of this measure duct 48 is connected to a distribution manifold 54 of the floor system, which is part of the floor radiant system 3 and comprises a delivery duct 55 and a return manifold 56.
  • the delivery manifold 54 is provided with several connectors 51, each provided with electrothermal valves 52, which allow to intercept the direct flows to the single household systems. These connectors 51 allow to connect in particular to the ducts 7 of the floor radiant system 3 of figure 1.
