Abstract

This invention is describing a procedure for building constructions, tanks, technological installations, etc., characterized by constructing around the building an additional supra-structures (FIG. 1b, 1g) avoiding the contacts with the first supra-structure and which supports a thermo insulating outer cover (1d), the components of the exterior installations (1j) and decorative elements (1k). For applying this procedure the invention is proposing a series on new procedures and construction materials: multi layered barriers (1d, made of gas layers with optimal thickness, support layers with the minimal thickness allowed by the producing technology or by the mechanical forces, spacers and an outside layer), thermos barriers (1f, made of a gas layer, saturated gas layer or vacuum, bordered by a frame and two reflecting support layers), variable resistance barriers, active barriers (1g, thermos layer with a positive or negative heat source), solar barriers (1h); thermo insulating foils (1g), plates (1h) and sheets (with 95% of volume being gas), multilayered plated with supervised central void, thermo insulating bricks (1c) with plane surfaces decorated, with faience, enameled, bricks for porous walls (for recovering the heat from the evicted air), detachable bricks, insulating window wall surfaces transparent or semi-transparent, pre-insulated pipes and fittings, different types of heat exchangers (1g), electrical, with air, with water or with fridge agent, heat economizers with fridge agent, panels (1m), lamellas (1l) and solar tubes, classical or with cold surfaces.

Claims

1. Thermo insulating system called pellicullar gas barrier made by assembling the following elements in specialized workshops or on site:

Minimum 2 solid layers made of same or different materials, tough or flexible, compact, with small punches or woven (called support layers), placed between the protective layers, parallel to each other, and separated by them and between them by

Point like distancing elements, perimeter frame, grill, etc placed in between the support layers through sticking, adhesion or obtained by processing the support layers;

when the distancing elements are missing, the support layers are fixed on the perimeter cover

One or more gas layers (called base layers), each placed between 2 support layers, unitary or divided by linear or grill like distancing elements

An outer cover (which ensures the mechanical protection and the assembly of the barrier) made in its turn from the following (independent, or built into a box, a bag or container) elements;

a. A protective outside layer (which can be the last support layer or the surface to be insulated)

b. An interior protector layer (which can be the last support layer or the surface to be insulated)

c. A perimeter cover, placed between the two protective layers, on their contour (which can be made of all the perimeter distance elements or of elements adjacent to the construction)

Optionally, in order to take part of the mechanical load of the cover;

d. One or more intermediate layers, parallel with the protective layers

e. One or more intermediate distance elements placed between the protective layers or between a protective and an intermediate layer

characterized by the fact that;

The thickness of the base layers is smaller than the minimal thickness (the thickness up until for the given temperature difference between the protective layers the convection and radiation heat transfer is negligible compared to the conductive heat transfer), limit that will be computed or experimentally determined.

The support layers are thinner than the base layers and are slightly tensioned, by adhesion or pressure of the corners and/or of the sides to the perimeter distancing elements and/or the perimeter cover

The number, shape, composition and size of distance elements are chosen so that the heat transfer through them is negligible versus the heat transfer through the base layer in which they are set

The weight of non convective gas volume in the total barrier volume is higher than 50%

5. Procedure for finding the limit thickness of the base layers in the pellicular gas barriers from claim 1, characterized by the fact that, for a certain pair of materials that compose the support layers and the base layers, a series of successive measurements of the thermal conductivity coefficient of the system is taken, starting form a minimal thickness that is successively increased by increasing the thickness of the perimeter distance elements, mentaining constant temperature between the protective layers.

6. Pellicular gas barrier as per claim 1 above named vacuum barrier, characterized by the fact that the pressure in at least one of the base layers is in the range of advanced vacuum, vacuum that can be periodically maintained turning on a vacuum pump coupled to the system;

in the other layers the pressure is equal to the atmospheric pressure or is progressively decreasing from one layer to the other from the protective layers to the vacuum layer.

10. Thermo insulating system, as per claim 1 above, called thermos barrier, characterized by the fact that some base layers are bordered by reflecting or transparent surfaces.

11. Vacuum barrier, as per claims 6 above, characterized by the fact that the vacuum base layers are bordered by reflecting surfaces (vacuum thermos barrier).

14. Pellicular gas barrier, as per claim 1 above called active barrier, characterized by the fact that in one protective layer or in an intermediate layer (active layer) a positive or negative heat source is introduced:

in order to flow the thermal radiations in the desired direction, one side of the active layer is reflecting surface and the other side is absorbing the radiations.

16. Pellicular gas barrier, as per claim 1 above called mobile barrier with variable resistance, characterized by the fact that one or more support layers can be distanced through flapping, sliding or rolling, allowing thus the thermo-insulating system to have different values for its thermal resistance, depending on the needs.

17. Device for protection and thermal screening for glassed surfaces of buildings and some installations (refrigerators, freezers), as well as for installations with periodical thermal processes and for parked autovehicles, characterized by the fact that it is a mobile barrier with variable resistance, as per claim 16, made of a bonnet manufactured from several fragments, from a soft thermo insulating material, and can have one or both surfaces reflecting surfaces, rolled in one or more fixed or mountable cassettes, and that can be freely rolled and then assembled with buttons, zippers, etc or are rolled so that the 2 sides of the bonnet are progressively inserted in a U shaped section frame.

18. Pellicular gas barrier, as per claim 1 above called fanned barrier with variable resistance, characterized by the fact that inside the walls of the exterior cover there are different devices used to easily replace the gas with a different fluid, stationary or moving one, in order to accelerate the heat transfer.

33. Pellicular gas barrier as per claim 1 above called carrying multilayered barrier characterized by the fact it is made of a carrying exterior cover and a thermo insulating core.

34. Thermo insulating system, as per claim 1 above, characterized by the fact that there are built in valves inside the exterior walls, while in the support layers there holes are created for a non-convective flow of the gas, so that the air or gas in the base layers can be vacuumed, can have its pressure decreased or can be replaced with a different gas.

38. Vacuum barrier, as per claim 6 above, characterized by the fact that between the exterior and the vacuumed layers there are communication channels by linking more very long channels with low diameter (built on each of the support layers by cuts inside frames or by using linear spacing elements), each of those channels having one end open towards the corresponding base layer and the other end open towards the previous base layer trough a hole in the support layer, so that when the gas is periodically extracted from the vacuumed layer there is a pressure fall along the channel that is progressively reducing the pressure among the layers.
