Definitions
- the invention relates to a duct for transporting air in an air conditioning installation, comprising a tubular body of mineral wool.
- This type of sheath is more convenient to produce than that comprising a metal sheet tube which is surrounded, after installation, by a thermally insulating sleeve.
- the internal face of the tubular body is bare or covered with a glass veil.
- the object of the invention is to remedy these drawbacks, by substantially reducing the friction of the air inside the sheath and the entrainment of dust.
- the invention relates in particular to a sheath of the kind defined in the introduction, and provides a coating on the internal face of the tubular body, this internal coating comprising a thin and smooth aluminum sheet whose internal face constitutes the internal face of the sheath.
- the internal coating is provided with a reinforcing layer linked to the external face of the aluminum sheet.
- the internal coating also comprises a second aluminum sheet, the reinforcing layer being sandwiched between the two aluminum sheets.
- the external face of the tubular body is also provided with a coating, this external coating being able to be folded without breaking.
- the external coating comprises a reinforcing layer sandwiched between an internal aluminum sheet and an external layer chosen from the group formed by an aluminum sheet and a sheet of kraft paper.
- the reinforcement layer is a polyethylene grid.
- the internal coating and / or the external coating are bonded to the tubular body using an aqueous-based vinyl adhesive.
- the tubular body is made of rock wool.
- the subject of the invention is also a plate usable for producing a sheath as defined above, by cutting and folding, this plate comprising a body of mineral wool and a coating on at least one face thereof, this coating comprising a thin and smooth aluminum sheet, one face of which constitutes one face of the plate.
- FIG. 1 is a partial cross-sectional view of a plate according to the invention.
- FIG. 2 is a schematic cross-sectional view of a sheath according to the invention obtained from the plate of Figure 1.
- the plate 20 shown in Figure 1 comprises a rock wool mattress 1 with a density of about 95 kg / m 3 with a thickness of 25 mm.
- On the two sides of this mattress are glued, using an aqueous-based vinyl adhesive, two coatings 2, 3 respectively, each coating being composed of a polyethylene grid 4 sandwiched between two aluminum sheets 5, 6.
- the adhesive used preferably has a calorific value sufficiently low to give the product as a whole the classification fire MO.
- Each of the coatings 2 and 3 has an overall thickness of the order of 20 microns.
- FIG. 1 also shows a notch 7 with a V-profile open at 90 th , made by cutting the covering 3 and the rock wool body 1, leaving the covering 2 intact.
- the plate can be folded 90 ° around the bottom 8 of the notch so as to bring the edges of the latter one against the other, as shown in FIG. 2.
- the sheath 9 has assembly edges 10, L-shaped, of the plate coming into mutual support at the fourth angle 11.
- the outer surface of this sheath is covered by the coating 2 which s extends continuously around its perimeter, while its four internal faces are covered by portions of the coating 3.
- the aluminum sheet 6 of the coating 3 like the other three aluminum sheets of the plate 20, is of a quality commonly used in construction and presents u do shiny face. This shiny face is preferably turned towards the inside of the sheath so as to further reduce the friction of the air.
- the grid 4 of the same coating 3 has in particular the effect of avoiding the initiation of a tear in the sheet 6 during the production of the notch 7. The presence of this grid also causes a slight undulation of the free surface. of the coating, which has no harmful consequences.
- Table 1 gives the energy loss coefficient ⁇ as a function of the Reynolds number, measured for a conduit straight section 250 x 250 mm and length 5800 m.
- Table 2 gives the coefficient ⁇ characterizing the energy loss in a 90 ° bend.
- the coefficient ⁇ of the conduit according to the invention is 0.017 against 0.022 for that comprising a glass veil, ie a gain of 23%.
- the coefficient ⁇ is reduced from 0.68 to 0.5, a gain of 26%.
- the coating 2 intended to ensure the external tightness of the sheath, can be constituted by any material or laminate impermeable to air, which can be glued and which can bend without breaking. It is envisaged in particular to replace the outer aluminum sheet 6 of this coating with a sheet of kraft paper.
