Abstract

The wall is exposed to solar radiation, and is composed of a rear thickness (1) accumulating and transmitting heat to an adjacent room, and of a front volume (2) provided with an air duct, so that, by convection, it conveys the solar heat to the thickness (1) without conveying the heat of the latter outwards. <IMAGE>

   REVENDICATION
 Paroi exposée au ravonnement solaire destinée à chauffer un local qui lui est adjacent, caractérisée en ce qu' elle comporte une épaisseur arrière pleine (1) pour l'accumulation et la transmission de la chaleur à ce local et un volume avant fermé (2) pour la circulation de l'air, le volume avant étant partagé en deux parties (4) et (5) par une couche isolante intermédiaire (3) de couleur noire du côté du soleil, supportant la chaleur et ouverte à sa partie supérieure et à sa partie inférieure pour former un canal dans lequel l'air circule par convection naturelle en montant dans la partie extérieure (5) et en descendant dans la partie intérieure (4), la surface avant du volume (5) étant un vitrage (6) muni en sa partie supérieure d'un clapet (7) qui empêche une circulation en sens inverse.



   En technique solaire existe ce que   l'on    appelle le mur
Trombe. C'est un gros mur doté de bouches d'aération en bas et en haut, limité vers l'extérieur par une couche d'air circulant derrière une vitre et devant une paroi noire. Cet air provient du local à chauffer adjacent, par les bouches du bas, se réchauffe, monte et retourne audit local par les bouches du haut. (voir  L'énergie solaire dans le bâtiment  par Ch.



  Chauliaguet, p. 125 et 126). L'inconvénient du système, c'est que le mur cède sa chaleur non seulement au local, mais aussi à l'environnement. D'autre part, I'air chaud pénétrant dans le local provoque des surchauffes.



   La paroi qui est l'objet de la présente invention élimine ces deux défauts. Nous en donnons ci-après la description. Elle se réfère à la fig. 1 et à deux coupes fig. 2 et fig. 3. La paroi (v. fig.   let    2) est formée successivement, en passant de l'intérieur vers l'extérieur, d'une brique Zida creuse de 24 cm remplie de béton (1), d'une brique Zida creuse de 14 cm (4), d'une isolation Foamglas (verre expansé noir) (3) laissant un passage sur toute sa largeur en haut et en bas, d'une couche d'air de 10 cm (5) et d'une vitre de 4 mm (6). En haut et en bas du mur la brique Zida de 14 est ouverte vers l'extérieur de telle sorte qu'en profil elle a une forme de E (fig. 3). Ceci permet l'établissement d'un courant d'air circulaire du canal extérieur (5) situé entre l'isolation (3) et la vitre (6) vers le canal intérieur des briques Zida 14. (4).



   La rayonnement solaire est transformé en chaleur par la surface noire du Foamglas (3), I'air du canal extérieur (5) s'en trouve être réchauffé et il monte. L'air du canal intérieur (4) s'en trouve être aspiré, il descend. Il s'établit une circulation d'air caloporteur qui dépose dans les briques Zida 14 la chaleur tirée du rayonnement solaire. Par conduction le mur de béton (1) est réchauffé à son tour, il accumule cette chaleur et, par sa face intérieure, il réchauffe le local par convection et rayonnement.



   Un clapet (7), situé à la partie supérieure, empêche l'air de circuler dans l'autre sens si le canal extérieur (5) est plus froid que le canal intérieur (4).

   CLAIM
 Wall exposed to solar heating intended to heat a room which is adjacent to it, characterized in that it has a full rear thickness (1) for the accumulation and transmission of heat to this room and a closed front volume (2) for air circulation, the front volume being divided into two parts (4) and (5) by an intermediate insulating layer (3) of black color on the side of the sun, supporting the heat and open at its upper part and at its lower part to form a channel in which the air circulates by natural convection, going up in the external part (5) and going down in the internal part (4), the front surface of the volume (5) being a glazing (6) provided in its upper part with a valve (7) which prevents circulation in the opposite direction.



   In solar technology there is what is called the wall
Waterspout. It is a large wall with air vents at the bottom and top, limited to the outside by a layer of air circulating behind a window and in front of a black wall. This air comes from the adjacent room to be heated, through the bottom vents, heats up, rises and returns to said room through the top vents. (see Solar energy in buildings by Ch.



  Chauliaguet, p. 125 and 126). The disadvantage of the system is that the wall gives off its heat not only to the room, but also to the environment. On the other hand, the hot air entering the room causes overheating.



   The wall which is the object of the present invention eliminates these two defects. We describe it below. It refers to fig. 1 and two sections fig. 2 and fig. 3. The wall (see fig. Let 2) is successively formed, passing from the inside to the outside, of a 24 cm hollow Zida brick filled with concrete (1), of a hollow Zida brick of 14 cm (4), Foamglas insulation (black expanded glass) (3) leaving a passage over its entire width at the top and bottom, a layer of air of 10 cm (5) and a window 4 mm (6). At the top and bottom of the wall the Zida brick of 14 is open to the outside so that in profile it has an E shape (fig. 3). This allows the establishment of a circular air flow from the outer channel (5) located between the insulation (3) and the glass (6) towards the inner channel of the Zida bricks 14. (4).



   The solar radiation is transformed into heat by the black surface of the Foamglas (3), the air of the external channel (5) is thereby heated and it rises. The air from the interior channel (4) is sucked in, it descends. A circulation of heat transfer air is established, which deposits the heat drawn from solar radiation in the Zida 14 bricks. By conduction the concrete wall (1) is heated in turn, it accumulates this heat and, by its inner face, it heats the room by convection and radiation.



   A valve (7), located at the top, prevents air from flowing the other way if the outside channel (5) is cooler than the inside channel (4).

CLAIM Wall exposed to solar heating intended to heat a room which is adjacent to it, characterized in that it has a full rear thickness (1) for the accumulation and transmission of heat to this room and a closed front volume (2) for air circulation, the front volume being divided into two parts (4) and (5) by an intermediate insulating layer (3) of black color on the side of the sun, supporting the heat and open at its upper part and at its lower part to form a channel in which the air circulates by natural convection, going up in the external part (5) and going down in the internal part (4), the front surface of the volume (5) being a glazing (6) provided in its upper part with a valve (7) which prevents circulation in the opposite direction.

In solar technology there is what is called the wall Waterspout. It is a large wall with air vents at the bottom and top, limited to the outside by a layer of air circulating behind a window and in front of a black wall. This air comes from the adjacent room to be heated, through the bottom vents, heats up, rises and returns to said room through the top vents. (see Solar energy in buildings by Ch.

Chauliaguet, p. 125 and 126). The disadvantage of the system is that the wall gives off its heat not only to the room, but also to the environment. On the other hand, the hot air entering the room causes overheating.

The wall which is the object of the present invention eliminates these two defects. We describe it below. It refers to fig. 1 and two sections fig. 2 and fig. 3. The wall (see fig. Let 2) is successively formed, passing from the inside to the outside, of a 24 cm hollow Zida brick filled with concrete (1), of a hollow Zida brick of 14 cm (4), Foamglas insulation (black expanded glass) (3) leaving a passage over its entire width at the top and bottom, a layer of air of 10 cm (5) and a window 4 mm (6). At the top and bottom of the wall the Zida brick of 14 is open towards the outside so that in profile it has an E shape (fig. 3). This allows the establishment of a circular air flow from the outer channel (5) located between the insulation (3) and the glass (6) towards the inner channel of the Zida bricks 14. (4).

The solar radiation is transformed into heat by the black surface of the Foamglas (3), the air in the external channel (5) is thereby heated and it rises. The air from the interior channel (4) is sucked in, it descends. A circulation of heat-transfer air is established, which deposits the heat drawn from solar radiation in the Zida 14 bricks. By conduction the concrete wall (1) is heated in turn, it accumulates this heat and, by its inner face, it heats the room by convection and radiation.

A valve (7), located at the top, prevents air from flowing the other way if the outside channel (5) is cooler than the inside channel (4). ** ATTENTION ** end of the CLMS field may contain start of DESC **.
