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 examples include US-A-3968831, US-A-3167159, DE-A-19647567, US-A-5433056, DE-A-1409994, US-A-3920953, SU-A-2671441, US-A-5014481, US-A-3463224, DE-A-4300839.
- FIG. 2 The document WO-A-03/054456 attempted to improve the situation by proposing a device of the type illustrated in FIG. 2 comprising a panel defined by two partitions 20, 22 separated by spacers 24 and delimiting a chamber 30 placed under pressure. ambient 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 clamped between the spacers 24 and the second partition 22.
- FIG. 2a when 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 to the membrane 32, the latter 32 being pressed against the second partition 22.
- FIG. 2a when 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 to the membrane 32, the latter 32 being pressed against the second partition 22.
- FIG. 3 which comprises a V-shaped deflector 40 to the base of the spacers 24, second wall side 22 and cradles 42 U on the first partition 20.
- 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.

- FIGS. 3a and 3b schematically represent two similar states of a device previously described, according to a second variant of embodiment taught by the document WO-A-03/054456,
- FIG. 6 represents a view of an improved device according to the present invention
- FIG. 7 shows the assembly of several elementary panels according to the present invention, singing against singing
- FIG. 8 represents the superposition of several panels of a thermal insulation device according to the present invention
- a thermal insulation panel 100 according to the present invention comprises two main walls 110, 120, separated by a main peripheral spacer 102 to form a gas-tight chamber 104.

- the films 150, 160 define between them gas-tight compartments 158 placed under a controlled vacuum level.
- the films 150, 160 being placed halfway from the walls 110, 120, they divide the chamber 104 into two sub-chambers 104a and 104b located respectively on either side of the compartments 158.
- communication means 103 for providing a fluid connection between the two sub-chambers 104a and 104b.
- These communication means 103 are moreover preferably adapted to ensure a fluid connection between a means 190 of pressure control, such as a compressor or equivalent means, and said chamber 104.
- the spacers 102 and 140 are made of a thermally insulating material so as not to constitute a thermal conduction bridge between the walls 110 and 120.
- the spacers 102, 140 are advantageously formed of thermoplastic material.
- FIGS. 4 and 5 The operation of the device according to the present invention shown diagrammatically in FIGS. 4 and 5 is essentially as follows.
- FIG. 4 shows a generator adapted to apply controlled polarity potentials respectively to the films 150, 160 and to the walls 110, 120.
- the two films 150, 160 When applying potentials of opposite polarities between the films 150, 160, on the one hand, and respectively identical polarities between each of the films 150, 160, and the wall 110, 120, opposite, the two films 150, 160 are pressed against each other mid-thickness of the chamber 104 as shown in Figure 4. They are thus placed in mutual contact at least over a substantial part of their surface, away from the walls, it is that is to say, separated from the walls 110, 120. In this state, the films 150, 160, in mutual contact, allow a certain thermal transfer by conduction between them.
- the pressure in the compartments 158 between the films 150, 160 is less than the pressure that prevails in the sub-chambers 104a and 104b situated on the outside of the films 150, 160, preferably less than 1 Pa, or typically comprised between 10 "3 and 10 " 4 Pascals.
- the voltages applied to the device respond to the relationship
- V / e 3,4.10 5 (p / s r) 1/2, in which relationship:
- V is the electrical potential
- e denotes the initial gap between the outer faces of the deformable flexible films 150, 160, and the surface facing the plates 110, 120, p represents the internal pressure in the chamber 104, and
- s r represents the permittivity of the medium filling chamber 104.

- FIGS. 9 and 10 show an alternative embodiment according to which three adjacent films are thus provided. , 160 and 170 at mid-distance between the walls 110, 120.
- the films 150, 160 and 170 are separated from each other by an air gap.
- the outer films 150, 170 are pressed against the walls 110, 120, in a position separated from the central film (s) (ux) 160.
- the device is then in a position of thermal insulation resulting from the separation between the films.
