Definitions

  • the present invention relates to a collector for distributing a heat transfer fluid in a heating and/or cooling and/or conditioning network, in particular of household and/or industrial type, according to the preamble of claim 1.
  • a collector is known from document DE 19642721 A1 .
  • a collector for distributing a heat transfer fluid in a heating and/or cooling and/or conditioning network, in particular of household and/or industrial type, is known in the art, wherein the collector comprises a housing, usually made of plastic or metallic material, which is provided with:
  • the collector of the type known in the art further comprises a port for a branching pipe, in particular said port being hydraulically connected to the duct and being usually arranged radially relative thereto.
  • the collectors known in the art also include a shut-off valve that allows controlling the opening and/or closing of said passage in order to either allow or prevent the fluid to flow from said duct into said at least one port.
  • thermo zone refers to any portion of a building which has uniform characteristics of utilization and exposure.
  • shut-off valves known in the art while they may be constructed for manual operation, usually operate automatically, since they comprise a servocontrol (which may be, for example, of electrothermal or electromechanical type) which is appropriately driven by a thermoregulation device installed in the served environment.
  • a servocontrol which may be, for example, of electrothermal or electromechanical type
  • Figures 1 and 2 show two different embodiments of a collector (designated as a whole by reference numeral 1) for distributing a heat transfer fluid in a heating and/or cooling and/or conditioning network, in particular of household and/or industrial type, according to the present invention.
  • the collector 1 is provided with a housing 10 equipped with:
  • the housing 10 of the collector 1 may be made of any material suitable to allow a heat transfer fluid for a heating and/or cooling and/or conditioning network to flow through the first terminal portion 11, the duct 13 and the second terminal portion 12.
  • the duct 13 is preferably so constructed as to have a substantially circular cross-section, in particular said cross-section being the one through which a fluid can flow.
  • the collector 1 is also equipped with a shut-off valve (designated as a whole by reference numeral 20) positioned at least partly in the duct 13 and comprising a movable obstructor 21 for adjusting the opening and/or closing of a passage 14 in said duct 13.
  • a shut-off valve designated as a whole by reference numeral 20
  • a movable obstructor 21 for adjusting the opening and/or closing of a passage 14 in said duct 13.
  • the passage 14 starts from a wall 15 that delimits the duct 13, in particular substantially perpendicularly to the development of the duct 13. Furthermore, the passage 14 is obtained on an intermediate portion of the duct 13; as a consequence, also said shut-off valve 20 may be substantially associated with an intermediate portion of the duct 13.
  • said shut-off valve 20 is so constructed that the movable obstructor 21 can be operated either manually, e.g. by means of a suitable control wheel (not shown in the drawings), or by means of an electrothermal or electromechanical actuator, which will tend to hold the movable obstructor 21 in the opening condition.
  • a suitable control wheel not shown in the drawings
  • an electrothermal or electromechanical actuator which will tend to hold the movable obstructor 21 in the opening condition.
  • the movable obstructor 21 is pushed and overcomes the countering force of a spring 22, thus moving into the position in which it closes the passage 14 (as shown in the annexed drawings).
  • the collector 1 comprises:
  • said chamber 30 is interposed between the passage 14 of the duct 13 and said plurality of ports 40; as a consequence, the chamber 30 allows putting the ducts 13 in fluidic communication with the plurality of ports 40 through said passage 14, in particular in the situation (not shown in the annexed drawings) in which no thrust action is being exerted on the movable obstructor 21 by the actuator and/or by the manual control that holds it in the closed condition, so that the countering force of the spring 22 brings it back into the position in which it opens the passage 14.
  • the chamber 30 defines a conduit that develops substantially parallel to the duct 13.
  • the chamber 30 is preferably obtained directly in said housing 10 of the collector 1, e.g. during the manufacturing stages (e.g. melting, moulding and/or subsequent processing); in this embodiment (shown in the annexed drawings), the chamber 30 is separated from said duct 13 by the wall 15, in particular the passage 14 being formed on said wall 15.
  • each port 40 of said plurality of ports 40 extends radially from said chamber 30.
  • the collector 1 may be so constructed as to comprise a variable number of ports 40 communicating with the chamber 30.
  • Figure 1 shows a collector 1 provided with two ports 40, so that it can distribute the heat transfer fluid to a pair of branching pipes directed towards the same "thermal zone"
  • Figure 2 shows a collector 1 provided with three ports 40, so that it can distribute the heat transfer fluid to three different branching pipes directed towards the same "thermal zone”.
  • the collector 1 according to the present invention may preferably be designed to comprise a number of ports 40 in the range of two to five. It is however clear that the principles of the present invention may also find application in cases wherein the collector 1 is so designed as to comprise a number of ports 40 greater than five.
  • the collector 1 may be so constructed as to comprise a plurality of ports 40 communicating with the chamber 30, wherein the ports 40 of one collector 1 are typically connected to respective branching pipes in order to distribute the heat transfer fluid homogeneously to the same "thermal zone" of a heating and/or cooling and/or conditioning network.
  • the peculiar provisions of the present invention thus allow providing a distribution collector 1 so conceived as to considerably reduce the purchase cost and the operating and maintenance costs thereof.
  • the provision of the chamber 30 interposed between the duct 13 of the housing 10 and the plurality of ports 40 allows the use of one and only one shut-off valve 20 in the collector 1, since said one shut-off valve 20 allows obtaining the opening or the closing of the passage 14 and, consequently, a diversified distribution of the heat transfer fluid to the different "thermal zones" of a heating and/or cooling and/or conditioning network.
  • collector 1 is so constructed as to comprise only one shut-off valve 20 also allows for a significant simplification of the processes to be carried out in order to install the collector 1 and the whole circuit it belongs to.
  • the first terminal portion 11 and the second terminal portion 12 comprise coupling means, in particular so realized as to extend in a direction substantially coaxial to said duct 13.
  • Said coupling means comprise:
  • the male connection portion 10M and the female connection portion 10F may be reversed, in that the male connection portion 10M may be located at the second terminal portion 12 and the female connection portion 10F may be located at the first terminal portion 11.
  • the size and shape of the female connection portion 10F are complementary to those of the male connection portion 10M; as a consequence, the female connection portion 10F of one collector 1 can receive the male connection portion 10M of a contiguous collector 1 (as can be seen in Fig. 3 ), so as to create a cylindrical tightening surface between said collectors 1.
  • the female connection portion 10F and the male connection portion 10M may be so constructed as to comprise respective threads (as shown in the annexed drawings) to facilitate the coupling between contiguous collectors 1.
  • connection portion 10F and the male connection portion 10M may then be each equipped with a seat (not shown) suitable for receiving a sealing element, e.g. a toroidal gasket (also not shown); said connection means 10F, 10M and said sealing element thus allow providing a modular collector 1, which can be easily and quickly assembled, and which is so constructed as to prevent any undesired leaking of heat transfer fluid flowing through a plurality of collectors 1.
  • a sealing element e.g. a toroidal gasket
  • said female connection portion 10F and/or said male connection portion 10M may also be associated with a closing element (e.g. a cap or a cover, not shown in the annexed drawings) for closing the first terminal portion 11 and/or the second terminal portion 12 and, as a result, for closing the duct 13.
  • a closing element e.g. a cap or a cover, not shown in the annexed drawings
  • the collector 1 may be so constructed as to comprise a variable number of ports 40 communicating with the chamber 30, and two or more collectors 1 can be assembled together in order to form a modular collector 1.
  • Fig. 3 one can see that, in accordance with the present invention, it is possible to assemble together two or more collectors 1 provided with a different number of ports 40, so as to be able to adequately distribute the heat transfer fluid in a diversified manner to the different "thermal zones" of a heating and/or cooling and/or conditioning network.
  • a first collector 1 with two ports 40 and a second collector 1 with three ports 40 are assembled together; it is therefore apparent that the first collector 1 with two ports 40 will be able to distribute the fluid evenly to a "thermal zone" with two points of utilization (such points of utilization being, for example, radiators), while in its turn the second collector 1 with three ports 40 will be able to distribute the fluid evenly to another "thermal zone" with three points of utilization. It must be pointed out that fluid distribution from the ports 40 to the respective points of utilization occurs through respective branching pipes (not shown in the annexed drawings).
  • the peculiar features of the present invention allow constructing the collector 1 in such a way as to considerably reduce the purchase cost and the operating and maintenance costs thereof.
  • the provision of the chamber 30 interposed between the duct 13 of the housing 10 and the plurality of ports 40 allows the use of one and only one shut-off valve 20 in the collector 1, since said one shut-off valve 20 allows obtaining the opening or closing of the passage 14 and, consequently, a uniform distribution of the heat transfer fluid, through said ports 40, to the points of utilization of a given "thermal zone" connected to the ports 40 of the same collector 1, and a diversified distribution to the different "thermal zones" of a heating and/or cooling and/or conditioning network which are connected to ports 40 of different collectors 1.
  • the provisions of the present invention allow for an adequate distribution of the heat transfer fluid in a diversified manner to the different "thermal zones" of a heating and/or cooling and/or conditioning network.
