Definitions

  • the present invention relates to the field of thermal insulation of buildings.
  • the present invention relates to the field of thermal insulation vacuum air or gas.
  • the envelope we can distinguish two families: on the one hand the family of metal envelopes where the seal is made in fact of steel or aluminum metal plates and, on the other hand the family consisting of all other envelopes, the most common case being that of an envelope consisting of an alternation of plastic and metallic (or metallized) polymer layers.
  • nanostructured porosity For core materials, the distinction is essentially about the nature of nanostructured porosity or not. Functionally, a nanostructured material is less sensitive than the others to a pressure rise in the vacuum panel. Therefore, the materials of this family can maintain a high thermal performance even if leaks (in practice unavoidable) allow gas to enter the component when it is used.
  • the vacuum is drawn to the manufacture of the component and it then relies on the core material and the sealing of the envelope to keep it at a level sufficient for the component to continue to provide lasting its insulation function.
  • Durable means the lifetime relative to the building envelope that is to say of the order of 10 to 40 years.
  • a "watch” a molecular sieve capsule that captures the gases in the component to maintain a vacuum pushed until 'its saturation prevents it from continuing to perform this function
  • the second family is that of vacuum insulators whose vacuum is maintained permanently by a vacuum pump connected to the component.
  • the sealing barrier that surrounds the core material is always metallic or metallized. It therefore causes a thermal bridge (conduction of heat) on the edges of the component. Thus, if one assembles side by side several components to achieve an insulating wall, the insulation level of the assembly, taking into account these thermal bridges, is much less than that of the current part.
  • the second problem comes from the presence of the core material.
  • the core material Even if a perfect vacuum were established in the component, there would remain a mode of transfer by conduction through the nanostructure solid matrix of the core material.
  • This inevitable phenomenon with this kind of component inevitably limits the thermal conductivity that it can reach to a minimum value of the order of 5 mw / m. K.
  • thermal insulation devices can be found in the documents US Patent 3968831 , US Patent 3167159 , DE-A-19647567 , US Patent 5433056 , DE-A-1409994 , US Patent 3920953 , SU-A-2671441 , US Patent 5014481 , US Patent 3463224 , DE-A-4300839 .
  • the document WO-A-03/054456 tried to improve the situation by proposing a device of the type illustrated on the figure 2 comprising a panel defined by two partitions 20, 22 separated by spacers 24 and delimiting a chamber 30 placed at ambient pressure or in depression and which houses a deformable membrane 32.
  • the membrane 32 is connected punctually to the partition 20 at a thermally insulating point 34. It is also pinched between the spacers 24 and the second partition 22.
  • potentials of opposite polarities are applied to the membrane 32 and the second partition 22 while potentials of the same polarity are applied to the first partition 20 and the membrane 32, the latter is pressed against the second partition 22.
  • the present invention now aims to propose a new thermal insulation device which has superior qualities to the state of the art in terms of cost, industrialization, efficiency and reliability, among others.
  • the present invention aims to provide new means for achieving a thermal insulation device capable of evolving between a state of high thermal insulation and a state of least thermal insulation, or relative thermal conduction.
  • a thermal insulation device in particular for buildings, characterized in that it comprises at least one panel comprising two walls separated by a peripheral main spacer to define a sealed chamber in gas, in depression, and at least two flexible films arranged in said chamber, fixed locally to secondary spacers, at intermediate points between the two walls and defining between them sealed secondary compartments, so that, by applying successive potentials of polarity chosen between the walls and the flexible films, the flexible films are moved between a first position of thermal insulation in which the films placed at the same electrical potential of polarity opposite to the electric potential of the walls, are separated from each other and in contact with the walls, the pressure in the secondary compartments defined between the films being less than the pressure prevailing in the chamber outside the compartments and a second position in which the films are separated from the walls and in mutual contact at least over a substantial part of their surface, said second position having thermal insulation properties lower than the first position.
