Definitions

  • the present invention relates to a central heating installation provided with a hot water circuit for domestic use or sanitary water and comprising a heating device comprising an envelope or ferrule, the lower part of which is provided with a burner, in particular of a gas burner and on which is wound or not a conduit in which the water circulates from the heating circuit, this circuit then crosses a bundle of fins located at the upper part of the envelope on the trajectory of the hot gases escaping from the latter to then be directed to a discharge pipe.
  • European patent N ° 89,400,269 (priority French patent N ° 88.01800) describes a central heating installation in which the exchanger is mixed. It mainly comprises a set of tubes used for heating domestic water, shaped as a pin or coil which are arranged inside flattened tubes. Said tubes form a block connected by elbows and a set of fins, they constitute the heating water circuit, the sanitary water being heated by said water.
  • This configuration ensures that the tubes of the domestic hot water circuit, arranged in a pin or coil in the flat tubes of the heating water circuit are not in contact with them.
  • the dimensions of said flattened tubes and of said tubes are chosen so that the volume of water contained between the flattened tubes and the meanders of the hairpin tubes is as small as possible.
  • This arrangement requires having at each end brazed or welded end pieces in order to close off the heating circuit as well as elbows serving to connect the respective circuits together.
  • the present invention proposes to provide an improved installation which does not have the drawbacks mentioned above.
  • Figure 1 is an overall perspective view of the assembly exploded showing the different constituents of the mixed exchanger A.
  • Figure 2 is a perspective view of the tubes shaped as a series of pins in two perpendicular planes two by two.
  • Figure 3 is a plan view of the assembly of the mixed exchanger A.
  • Figure 4 is a plan view in side elevation of the mixed exchanger A.
  • Figure 5 is a plan view in front elevation during assembly of the mixed exchanger A.
  • the heating appliance object of this invention, comprises a first duct 2 for heating the water of the central heating circuit and a second conduit 1 for heating domestic water.
  • the duct 2 of the heating circuit is in the form of a series flattened tube pins such as 2 which each have a cross section of oval shape, the largest axis being horizontal.
  • These tubes are connected at one of their ends by elbows obtained by bending these said tubes.
  • the domestic water pipe 1 consists of a tube, preferably of circular cross section, disposed inside the flattened tubes 2 of the heating circuit, shaped into a series of pins obtained by bending said tube in two perpendicular planes two by two. This increases the heat exchange surface between the two circuits of the mixed exchanger since all the bends are in the heating circuit and not outside.
  • the positioning of the tubes of the pin-shaped sanitary circuit arranged inside the flattened tubes of the heating circuit is carried out so that there is no physical contact between the walls of the tubes 1 and 2, and so that the volume of water contained in the residual annular space is as small as possible. It also results from this configuration that all the calories conveyed by the heating circuit are transferred into the sanitary water circuit.
  • the respective assembly of the constituent sub-assemblies is as follows: the tubes 1 shaped as a hairpin of the sanitary water circuit, provided with plastic rings 6, are inserted inside the flattened tubes 2 of the water circuit of heating, while the fins 3 and the manifold 4 thread on the flattened tubes 2 of the heating circuit, the cover 5 completely closing off the assembly. This collector guarantees the routing of the heating fluid as well as the tightness of the assembly.
  • This collector 4 maintains the two circuits of the exchanger. It is soldered to the heating water circuit.
  • Reading the above description shows that the invention provides a heating installation ensuring perfect heat exchange between the two incorporated circuits of heating water and sanitary water thanks to a large heat exchange surface obtained by the configuration. the different circuits.
