Definitions

  • the invention finds advantageous application (without thereby losing its generality) in the field of air-handling systems such as, for example, ventilation systems, air conditioning systems or aeration systems.
  • the air is conveyed inside a plurality of ducts (box-like structures) connected to one another so as to allow the passage of air inside the same.
  • the ducts define box-like structures, which are made by connecting a plurality of box-like walls to one another.
  • the air conveyed inside the duct has a pre-established temperature, which must be as constant as possible throughout the entire path.
  • box-like walls that is, panels that comprise a sheet metal shell comprising an inner panel and an outer panel and that define a space between the same in which heat and sound insulating material is arranged), so as to thermally and acoustically insulate the wall.
  • the connecting flaps arranged at the ends of the inner panel and of the outer panel are overlapped and joined to one another by placing the same side by side. At these joints, where the outer panel is in contact with the inner panel, they transmit heat from the inside to the outside, or vice versa, thus establishing a so-called thermal bridge, leading to a possible unwanted formation of condensation on the panel itself.
  • walls have been produced that comprise an insulating element placed between the inner panel and the outer panel.
  • the insulating element is formed by a flat layer of insulating material arranged between the two walls. This solution, however, is not sufficient and allows poor results to be achieved in reducing the thermal bridge.
  • Insulating elements that further distance the two panels from one another are also known. However, these insulating elements can only be used in structures that use an outer frame (for example in aluminium or other materials) to which the walls are then fixed in order to ensure the stability thereof.
  • an outer frame for example in aluminium or other materials
  • the known type box-like structures are formed by a plurality of box-like walls connected to one another.
  • the box-like walls have faces at the connection areas that are side by side and adjacent to one another, which are orthogonal to the longitudinal extension of the duct and that are flat. Therefore, in the currently known box-like structures, in addition to or instead of the forming of the thermal bridge, the disadvantage may arise that the flat faces, which require perfect flatness, favour the leakage (in and out) of fluids, such as air. Furthermore, through the hollow spaces formed between the two connected box-like walls, particles can undesirably enter the duct itself.
  • sealing elements have been arranged between the two flat faces in the past, but these are not able to guarantee leak tightness.
  • Flat-faced box-like walls also have the disadvantage that they are difficult to install, as the walls to be connected must be perfectly aligned with one another, a condition that is difficult to satisfy at the time of installation on site.
  • the object of the present invention is to provide a box-like wall of an air-handling unit and a box-like structure comprising said box-like wall which are free from the drawbacks of the state of the art and that are easy and inexpensive to produce.
  • a box-like wall of an air-handling unit is provided as claimed in the independent claims that follow and, preferably, in any of the claims dependent directly or indirectly on the independent claims.
  • an air-handling unit is provided with said panel as claimed in the independent claims that follow and, preferably, in any of the claims dependent directly or indirectly on the independent claims.
  • each pair of portions 11B are opposite (that is, they protrude from two edges 10B of the portion 9B that are opposite to one another) and parallel to one another so that one of the end portions 11B of the pair defines an insertion portion 23 (in particular the end 11B that extends beyond the side dimensions of the central portion 9B) that is engageable, in use, with another box-like wall 5 (in particular in the seat 24 of the other box-like wall 5 to which it is connected).
  • the other end portion 11B of the pair of portions 11B of the same outer panel 7 defines a seat 24 that is engageable, in use, with an insertion portion 23 of another box-like wall 5.
  • the end portion 11B of the pair of portions 11B defining the seat 24 remains within the dimensions of the central portion 9B (namely, it does not extend beyond the side dimensions of the central portion 9B) thus defining the seat 24.
  • the element 12 does not protrude beyond the side dimensions of the wall 5 and in particular of the outer panel 7.
  • the section 19 therefore defines an abutment at which, in use, the walls 5 are connected to one another. Therefore, the section 19 ensures that during assembly, the element 12 cannot be inadvertently damaged, such as drilled, thus compromising its function of breaking the thermal bridge.
  • the thermal insulation element 12 not only prevents the thermal bridge from forming between the two panels 6 and 7, but also contributes to the seal against leaks and prevents humidity, water, or any other unwanted element (for example, particles) from infiltrating into the air-handling unit.
  • the box-like wall 5 with the end portion 11B provided with at least the bent section 19 at the angle ⁇ has the advantage that the wall 5 itself defines on one side (in particular the end 11B which extends beyond the side dimensions of the central portion 9B) the insertion portion 23 and on the other side (in particular the end 11B which remains within the side dimensions of the central portion 9B) the seat 24.
  • the seat 24 of a wall 5 acts as a solicitation for the insertion portion 23 of another wall 5 to be connected, thus guiding the coupling between the two.
  • the coupling that is formed is a shape coupling ensuring that the two walls 5 are kept in a respective position relative to one another.
