It comprises a frame structure formed by at least two steel mesh sheets (1, 2) fixed to each other with steel wires (3) welded to the steel meshes, a heat insulation layer (6 ) arranged in the centre of the frame structure, where the internal steel mesh 2 is encased in a first concrete layer (4), and the external steel mesh 1 is encased in a second concrete layer (5). A coil-pipe (7) is fixed on the external steel mesh 1, encased in the second concrete 5 and covered by the heat insulation layer (6), said coil-pipe (7) is connected to another coil-pipe (9) arranged under the surface of the soil in a depth of 1 - 150 m. The two coil-pipes (7, 9) form a common circuit, said circuit being provided with a pump (10) circulating the heat insulating fluid and an expansion tank (11).

The object of the present invention is to construct a building with low structural thickness, in a simple manner, in a simple manner, using the renewable energy of the earth, to achieve significant energy savings.

The objectives set for the active thermal insulation structure of the present invention have been recognized by the fact that the low-temperature, renewable energy of the earth is not used for heating but for active thermal insulation, which results in significant energy savings compared to known solutions.

For the active thermal insulation of the structure, only the minimum energy of the liquid pump is required. The present invention enables active thermal insulation of the building as well as noise and drafts-free cooling because the heat exchange takes place without air movement.

In order to heat the interior, a medium with a higher temperature than the internal temperature is required, but high-temperature medium from renewable energy sources is only available to a minimum or can be obtained with costly investment (eg solar collector, geothermal heat source from deep wells, heat pump, etc.). The low-temperature, renewable, free energy required by the present invention is available indefinitely, continuously, in winter-summer, day and night, and can be obtained in a relatively simple manner. (The serpent is 1.5-2.0 m deep below the surface of the soil, or a soil probe, a fluid circulating pump, an expansion vessel, a wall coil in a wall and a slab.) (Figure 2)

An embodiment of the present invention is a prefabricated panel (Figures 1-2) with active thermal insulation.

Insulated panels of spatial steel mesh forming the load-bearing layer can be produced in large series on automatic machine lines. Their weight is very small compared to conventional building materials and therefore no lifting equipment is required for construction. Large panels make construction extremely fast. The assembled panels can be assembled (electricity, water, etc.) without dismantling and repairs before applying the 4 and 5 load bearing concrete layers. There is no need for bridges towards the openings due to the stability of the structure. The thermal insulating layer 6 in the load-bearing structure provides good thermal insulation to the interior of the panel. Due to the cross-linked steel structure, structures made of this structure are resistant to earthquakes and typhoons, and 4 interior concrete layers provide adequate fire resistance. The pipe coil 7 required for active thermal insulation can be fastened to the steel mesh 1 quickly and easily before applying the concrete layer 5. In addition to its static function, the steel mesh underneath the pipe serpentine provides a rapid and even distribution of the heat delivered in the pipe coil, thereby accelerating heat exchange. The structure makes it possible to insulate both walls and slabs with the same technology.

Buildings made according to the present invention, with less structural thickness, provide considerably less heat loss to the building than the prior art solutions. The 4 concrete layers on the inside of the building have a good thermal inertia, thus improving the internal comfort. The inner layer is solid and loadable (eg important for wall-mounted cabinets and different equipment).

The active thermal insulation structure of the present invention is also suitable for the construction of energy efficient or passive family houses and multi-storey public buildings in a simpler way than the current state of the art.

Current state of the art

U.S. Patent Nos. 6,272,805 B1 and US 7,067,588 B2 disclose a building element of a cross-linked steel structure insulated panel. These building blocks allow the construction of cost-effective, durable, easy and quick-to-build buildings, but their thermal insulation properties are not competitive with other building components and systems that meet today's heat insulation needs. The outer concrete layer is subjected to high heat loss, which can lead to the cracking of the concrete surface and thus damage the structure. The building structure alone does not allow the building to be cooled.

HU 185 052 discloses a structure in which the wall structure is formed from U-shaped glass bodies so as to have vertical channels adjacent to each other. These channels are used to flow fresh air or exhausted air from the room. The solution is generally recommended for use in ventilation systems. The disadvantage of the solution is that the field of use is very narrow, as only the walls made of U-shaped elements are utilized. Air with a small heat of heat can only convey appropriate heat under special conditions, and a large amount of air flow is very noisy, and air ducts do not provide adequate sound insulation between the rooms.

DE 3843067 discloses a technical solution in which the building has hollow space bounding walls. In the cavities as air passages, fresh air drawn from the environment takes over part of the heat flowing through the walls. The fresh air preheated in this way is mixed with indoor air and then heated by the heat pump.

The disadvantage of this technical solution is the use of low heat air as a heat transfer medium and the use of expensive heat pumps.

Soil heat as a renewable free energy source is already widely used, primarily as a source of energy for heat pumps. The heat pump produces high-temperature media using electricity, which is used for heating.

The disadvantage of this solution is its high investment cost and high electricity demand.

The present invention maintains all the advantages of the technical solution described in the prior art US 6,272,805 B1 and US 7,067,588 B2.

EN 227 029 Β1 ve low-temperature (8-12 ° C) soil directly leads to a pipe coil attached to the external steel mesh of the building structure without any modification and allows low-temperature, free energy to be used for active thermal insulation instead of heating. In addition to its static function, the steel mesh underneath the pipe serpentine provides a rapid and even distribution of the heat delivered in the pipe coil, thereby accelerating heat exchange. The amount of heat flowing out of the interior space through the unit wall / slab surface is significantly less with the active thermal insulation than without it. Energy savings can be as high as 50-80%. To operate the system, only the minimum electrical energy of the fluid circulation pump is required. (Figure 3) In winter, when the outside temperature (t,) is higher than the internal temperature (t _e ), the heat loss of the interior (Q,) is the difference between the soil temperature (t,) and the ground temperature (t _f ). is determined by the thermal insulation factor of the inner wall part independently of the outside temperature (t _e ), if the fluid flowing in the pipe coil provides a constant soil temperature in the wall structure by a properly defined liquid stream.

The difference between the ground temperature (t _f ) and the outside temperature (t,) and the external wall portion (Q _f ) determined by the thermal insulation factor of the outer wall section provide a low heat output from the soil with the liquid flow.

In summer, when tj <t _e (Fig. 4), i.e., the outside temperature is higher than the internal temperature, the active thermal insulation structure does not allow the internal Q to transport _this exterior heat load and to the soil from the interior. amount of heat. If the outside temperature (t,) is between the ground temperature (t _f ) and the required internal temperature (t _e ), then the pump is not practical.
