Definitions
- the invention relates to a building equipped with a thermal regulation device by solar energy.
- a first technique consists in transforming the solar energy received into electricity via photovoltaic panels.
- a second technique is to heat water by solar exposure to produce hot water or supply a hot water heating system.
- a third technique is to use sunshine to heat the interior of the building through glazing.
- the present invention improves the situation.
- the invention relates to a building incorporating a thermal regulation device and having a surface having an orientation adapted to receive solar radiation, constituted by an outer face of the building wall wall, said thermal control device comprising :
- a first circulation duct for a heat transfer fluid adapted so that the fluid flowing inside said first duct accumulates heat produced by said solar radiation
- a second fluid circulation duct coupled to the first circulation duct and arranged to restore to the interior of the building heat previously accumulated by the fluid, when said fluid flows through the second duct;
- the principle of the invention therefore consists in heating a heat transfer fluid, for example water, by circulating it along a surface of the building receiving solar radiation through a duct integrated in a layer of insulating coating covering this surface, then at least partially restore the stored heat to the interior of the building by circulating it through a second conduit placed appropriately and integrated in a layer of insulating coating covering another wall wall, having a role of thermal regulation and whose orientation is different from that of the surface oriented to receive solar radiation.
- the fluid flowing in the second duct transmits its heat towards the interior of the building through the wall of thermal regulation.
- the invention applies more particularly to new buildings and to rehabilitate and whose interior is little or not isolated. It is particularly applicable to buildings located in areas requiring high insulation such as regions or countries bordering the Mediterranean, but also Asian countries such as India or China.
- the first circulation duct is disposed near the outer surface of the insulating coating layer covering the surface whose orientation is adapted to the reception of solar radiation. Thanks to this, the fluid recovers a maximum of heat produced by solar radiation.
- the second circulation duct is disposed against or near the outer surface of the thermal control wall wall.
- the heat transfer between the fluid and the thermal control wall is optimized.
- the wall wall along which the first pipe is disposed is advantageously exposed to the south (respectively north) or partially to the south (respectively partially to the north).
- the exposure of the thermal control wall wall has a main component oriented north, in the case of a building located in the northern hemisphere, and a main component facing south in the case of a building located in the southern hemisphere.

- it comprises a third fluid circulation duct, placed in the ground, and a coupling / decoupling element adapted to concomitantly uncouple the first and second circulation ducts and couple the second and third circulation ducts, the coupling of the second and third circulation ducts being adapted so that the fluid flows through the third duct, cooling thereto, and then flows through the second duct by cooling said thermal control wall wall.
- the thermal control device can be used to cool the building interior during a period of high temperatures.
- it comprises a fourth fluid circulation duct, placed in the ground, and a coupling / decoupling element adapted to concomitantly uncouple the first and second circulation ducts and to couple the first and fourth circulation ducts, the coupling of the first and fourth circulation ducts being adapted so that the fluid flows through the fourth duct cooling thereto and then flows through the first duct cooling the insulating coating layer covering the surface having an orientation adapted to receive solar radiation. Thanks to this, the thermal control device can be used to avoid an excessive increase in the layer of insulating coating covering the surface oriented to receive solar radiation.
- the invention also relates to a thermal regulation device for a building comprising a surface having an orientation adapted to receive solar radiation, constituted by an outer surface of a building wall wall, said device comprising

- the first duct 9 is positioned at approximately four centimeters from the wall wall 1. Then, the coating is projected on this initial thickness of 4 cm, so that the first duct 9 is flush with the surface. The plaster projected on such a thickness is thermally insulating. An additional thickness of about one centimeter of plaster is then projected to cover the duct 9. This additional layer of plaster is thermally conductive, given its small thickness. This forms an insulating coating layer juxtaposed with a layer of conductive coating. The conductive coating layer is the outer layer of the facade. The conduit 9 is positioned in the insulating coating layer and is flush with the surface separating the insulating coating and the conductive coating. The conduit 9 is contiguous to the conductive coating layer.

- a step S5 the fluid circulates through the circulation duct 10. Part of the heat previously stored during the south-side circulation is transmitted through the duct 10 and through the wall wall 3 towards the interior of the duct 10. building. The heat stored in the south is thus restored at least partially to the north.
- the fluid cooled (at least partially) after having circulated against the north wall 3 is reinjected by the pump in the duct 9 located on the south side, during a step S6.
- Steps S1 to S6 are then repeated.
- FIG. 4 there is shown:
- the thermal control device may comprise a control unit of the pump intended to control the starting and the interruption of the operation of the pump.
- this control unit can be programmed to control temporary interruptions of the pump, and thus a temporary stop of the circulation of the fluid, outside the periods of sunshine of the building on the side of the face having a orientation adapted to receive solar radiation (that is to say here south side), especially at night, during predefined time periods during the day and / or depending on the weather conditions.

- the three-way valve In operation, when it is desired to cool the interior of the building, in case of high heat and / or sunshine on the side of the F1 side of heat storage, the three-way valve is controlled so as to couple the conduit 9 and the cooling duct and thereby form a closed circulation circuit comprising the pump. Under the action of the pump, the fluid circulates through the cooling duct, cooling therein, then flows through the duct 9 by cooling the insulating coating layer 5. This prevents the layer 5, and by consequently, the wall wall 1 rises too much in temperature.
