Abstract

The invention consists of covering one surface of the slats of adjustable shutters or blinds with an absorbing surface and the other surface with a reflecting surface in order to absorb or reflect heat according to the selected orientation. This amounts to installing natural air-conditioning while letting light through.

Description

DISPOSITIF SIMPLE DE REPARTITION DES APPORTS SIMPLE DEVICE FOR THE DISTRIBUTION OF THE CONTRIBUTIONS
SOLAIRES ENTRE CHALEUR ET LUMIEREBetween heat and light
L'état de la technique consiste à faire entrer le soleil lorsqu'il est nécessaire de chauffer le lieu et à l'empêcher de rentrer lorsqu'il fait déjà trop chaud. Les systèmes connus pour assurer cette régulation sont des volets, rideaux, persiennes, stores à lames. Ce dispositif de climatisation comporte un store à lames recouvertes d'un premier matériau réfléchissant la lumière sur une face et un deuxième matériau absorbant la lumière sur la seconde face. L'objet de l'invention est un moyen d'absorber le soleil lorsqu'il est nécessaire de chauffer le lieu et de le réfléchir lorsqu'il fait déjà trop chaud. On obtient ce résultat en employant un écran orientable biface ; une des faces exposables au soleil est un corps noir mat, absorbeur de chaleur, tandis que l'autre est un corps réfléchissant tel qu'un métal poli, miroir... Le premier matériau peut être formé d'une pellicule métallique spéculaire. Le deuxième matériau peut être formé d'une couche de graphite ou d'une couche de peinture noire.The state of the art is to bring in the sun when it is necessary to heat the place and prevent it from entering when it is already too hot. Systems known to provide this regulation are shutters, curtains, shutters, blinds blades. This air conditioning device comprises a blade blind covered with a first material reflecting light on one side and a second light absorbing material on the second side. The object of the invention is a means of absorbing the sun when it is necessary to heat the place and reflect it when it is already too hot. This result is achieved by employing a two-sided swiveling screen; one side exposed to the sun is a matt black body, heat absorber, while the other is a reflective body such as a polished metal mirror ... The first material may be formed of a specular metal film. The second material may be formed of a layer of graphite or a layer of black paint.
Une des façons pratiques de mettre en œuvre l'invention est d'équiper les surfaces exposées au soleil (murs fenêtres et toitures) de lames ou de lamelles bifaces orientables qui se tournent en fonction des besoins. Le dispositif peut être équipé d'un orienteur pour orienter les faces des lames de manière à recevoir la plus grande quantité de lumière. Cet orienteur peut être équipé d'un dispositif pour mesurer la température, d'un dispositif pour orienter les lames et enfin d'un dispositif pour choisir celle des orientations qui permet de recevoir le plus de lumière. Ces lamelles peuvent aussi bien être entre des vitrages qu'à l'intérieur du lieu à climatiser.One of the practical ways to implement the invention is to equip the surfaces exposed to the sun (walls windows and roofs) blades or slats biface orientable that turn as needed. The device can be equipped with an orientator to orient the faces of the blades so as to receive the largest amount of light. This orientator can be equipped with a device for measuring the temperature, a device for orienting the blades and finally a device for choosing the orientation that allows to receive the most light. These slats can be between glazing and inside the place to be air conditioned.
Ces lamelles peuvent aussi bien être installées sous le vitrage d'une toiture bien exposées au soleil que sur la surface d'un mur, que dans ou derrière une fenêtre, que devant un panneau de chauffe-eau solaire pour assurer la régulation thermique. Ainsi, en hiver et de jour les lamelles sont orientées plus ou moins faces noires perpendiculaires au soleil.These slats can as well be installed under the glazing of a roof well exposed to the sun as on the surface of a wall, that in or behind a window, than in front of a panel of solar water heater to ensure the thermal regulation. Thus, in winter and during the day the lamellae are oriented more or less black faces perpendicular to the sun.
En hiver et de nuit, les lamelles forment un écran faces réfléchissantes vers l'intérieur afin de réfléchir les calories chauffées vers l'intérieur Un perfectionnement de l'invention consiste à équiper les parties closes où sont installées les lamelles bifaces de systèmes de ventilation afin de mieux exploiter les calories produites.In winter and at night, the slats form a reflective-facing screen inward to reflect heated calories inwards An improvement of the invention is to equip the closed parts where are installed the two-sided slats of ventilation systems to better exploit the calories produced.
Un perfectionnement de l'invention consiste à insérer les lames à l'intérieur d'un boîtier transparent ou translucide muni d'orifices de ventilation. La ventilation peut être gérée par un ventilateurAn improvement of the invention consists in inserting the blades inside a transparent or translucent housing provided with ventilation openings. Ventilation can be managed by a fan
En été et de jour, les lamelles sont orientées faces réfléchissantes perpendiculaires au soleilIn summer and daylight, the slats are oriented reflective faces perpendicular to the sun
Les lames peuvent avoir un profil incurvé et posséder sur la partie convexe le matériau absorbant et sur la partie concave, le matériau réfléchissant ou inversement, suivant que l'on veut privilégier la captation ou la réflexion de la lumièreThe blades can have a curved profile and have on the convex part the absorbent material and on the concave part, the reflecting material or vice versa, depending on whether we want to favor the capture or reflection of the light
Pour améliorer l'efficacité du système, les lames peuvent être constituées d'un matériau conducteur de la chaleur.To improve the efficiency of the system, the blades may be made of a heat conducting material.
Un autre aspect de l'invention est de munir au moins la face extérieure d'un volet de miroirs. Ainsi l'été, les volets fermés protègent du soleil en même temps qu'ils réfléchissent les rayons. Si le volet est aussi équipé d'un miroir côté intérieur, la chaleur se réfléchit sur ce dernier, minimisant les déperditions calorifiques.Another aspect of the invention is to provide at least the outer face of a flap of mirrors. In summer, closed shutters protect from the sun while reflecting the rays. If the shutter is also equipped with a mirror on the inside, the heat is reflected on the latter, minimizing heat loss.
Un autre aspect de l'invention est qu'une lame tournant sur un axe virtuel sensiblement horizontal a son côté absorbant débattant de 180° environ vers le haut et son côté réfléchissant débattant de 180° environ vers le bas.Another aspect of the invention is that a blade rotating on a substantially horizontal virtual axis has its absorbing side debating about 180 ° upwards and its reflective side debating about 180 ° downwards.
Une lame tournant sur un axe virtuel sensiblement vertical a son côté absorbant débattant de 180° environ côté lumière et son côté réfléchissant débattant de 180° environ côté intérieur. A blade rotating on a substantially vertical virtual axis has its absorbing side debating about 180 ° light side and its reflective side debating about 180 ° on the inside.
