Definitions

  • the present invention relates to double pressurized glazing.
  • double glazing is generally classified into two main categories, namely insulating glazing and breathing glazing.
  • the air space trapped between the glass sheets is completely separated from the ambient atmospheres and, to avoid possible condensation of humidity inside the glazing on the glass sheets, a hygroscopic product is usually provided. , able to absorb moisture, inside the glazing.
  • the air gap which separates the glass sheets having a constant volume the pressures and the forces exerted on the glazing sheet turned towards the outside of the room will be partially or fully transmitted (depending on the thickness ratio) to the sheet arranged inwards, which makes it possible to significantly reduce the thickness of the external glass sheet, without altering the mechanical resistance properties of the glazing.
  • so-called "breathable" glazing the volume of air separating the two glass sheets communicates in a controlled manner with the outside, so that the vapor pressure inside the glazing is substantially the same as at outside, which eliminates the risk of condensation.
  • part of the air trapped between the glass sheets can be evacuated to the outside, the forces exerted on the outer sheet is not transmitted to the sheet disposed inwardly and therefore it is not possible to reduce the thickness of the outer sheet.
  • Double glazing of the prior art is intended to separate atmospheres having different temperatures and likely to vary widely and frequently.
  • the present invention aims to provide a double glazing intended for more complete use, namely to separate two atmospheres which are substantially constant at identical or little different temperatures, as is the case, for example, for an unheated room , intended to serve as a warehouse or storage place.
  • An object of the invention is therefore to propose a double glazing suitable for such use.
  • Another object of the invention is to provide double glazing of this type, which does not present a risk of condensation between the two sheets of glass which it comprises.
  • the invention finally aims to provide a double glazing meeting these requirements, in which the forces exerted on the glazing arranged outside can be transmitted to the other glazing, which reduces the sum of the two thicknesses of the glazing.
  • the invention relates to a pressurized double glazing, usually comprising two glass panels mounted in parallel on a support frame and trapping between them in a substantially airtight manner a volume of air, this double glazing being characterized in which it comprises a means for supplying clean, dry air under pressure of the volume which separates the glass panels and a means for discharging this air under pressure.
  • the means for supplying and discharging pressurized air may simply comprise two conduits, connected respectively to a source of dry and clean air and to an exhaust manifold and each opening into the volume which separates the two panels. of glass by a nozzle having an orifice of very small diameter, making it possible to maintain a constant air flow, of very low flow rate, of the order, for example, from 1 to 100 l / h, and under a low relative pressure, on the order of 0 to 5000 Pa, for example.
  • the double glazing will also include a means of controlled communication with the outside of the volume which separates the two sheets of glass.
  • This means will for example include a calibrated orifice nozzle of very small diameter communicating with the outside.
  • the thickness of the two glazing units can therefore be calculated according to DTU 39 Insulating Glass, namely, if the difference in thickness between the outer skin and the inner skin is very large (infinitely flexible outer skin, skin interior infinitely rigid), bring in the suction effect in order to almost completely transmit the pressure / depression effects on the interior skin.
  • the glazing according to the invention it is not necessary, with the glazing according to the invention, to provide in normal use a hygroscopic product between the glass panels, but it will be advantageous, in practice, to provide a small amount of a such desiccant in the internal volume double glazing. Indeed, during the production of double glazing, the air trapped in it contains a certain amount of humidity and, when the double glazing is then stored at temperatures lower than that prevailing during its production, condensation risks to happen inside of it.
  • the double glazing according to the invention will naturally be delivered to users with all the openings which it comprises (and in particular the external orifices of the conduits with which it is equipped) closed hermetically, in order to avoid any introduction of ambient humidity into the volume. separating the glass panels.
  • the glass panels facing the exterior of the building are designated by the reference 1 and the panels facing the interior of the premises 10 are marked with the reference 2.
  • the panels 1 and 2 are respectively framed by metal profiles 3 and 4, with the interposition of an elastomer or a plastomer, respectively 5 and 6, which provides sealing along the entire periphery of the panels 1 and 2.
  • Profiles 3 and 4 can be of different types (aluminum or stainless steel) provided that the material is impermeable to water vapor. Profile 3 keeps the panels 1 and 2 at constant spacing and is made integral with profile 4 by mechanical fixing.
  • air under low pressure is supplied at a substantially constant flow rate, under low pressure, through a first conduit 9, from a source of pressurized air, in the internal volume 15 limited by the panels 1 and 2 and profiles 3 and 4, and this air is evacuated through a duct 10, equipped with a system filtration, intended to retain dust and other particles in suspension.
  • the conduits 9 and 11 open into the volume 15 to be pressurized by fittings such as 12, comprising an orifice of very small diameter, of the order of, either directly, or via closed volumes such as that referenced 13 of the profile 3, which themselves communicate through orifices 14 of the order of a few tenths of a millimeter with the volume 15.
  • fittings such as 12, comprising an orifice of very small diameter, of the order of, either directly, or via closed volumes such as that referenced 13 of the profile 3, which themselves communicate through orifices 14 of the order of a few tenths of a millimeter with the volume 15.
  • the connection of the supply duct 1 is offset laterally on the profile 3 and this is the reason why it does not appear in the drawing.
  • a third conduit 16 communicating with the outside atmosphere opens out through a fitting 17 into a closed volume 18 of the profile 1, itself in communication through an orifice 19 of a few tenths of a millimeter with the outside ambient atmosphere.
  • the orifice 19 will advantageously be equipped with a filter element.
  • a moisture absorbing product may be present in volume 15 or in one of the volumes such as 13 of the profile 3 communicating with volume 15, in order to absorb moisture initially present in this volume 15, after manufacture of the glazing. Due to the leakage to the outside provided by the fitting 17, the volume 18 and the orifice 19, the humidity level in the volume 15 will thereafter be the same as outside and, like the temperatures in the room and outside will also be identical, there will be no fear of condensation on the glass panels 1 and 2.
  • the invention therefore provides a simple and easy to implement means for equipping double glazing with unheated premises, which are appreciably in all seasons at room temperature, without risk of condensation on the glass panels, under these very special conditions of use.
  • thermoplastic according to the invention lies, moreover, in the durability of this pressurized complex, which is identical to that of its constituents.
