DESCRIPTION
La présente invention concerne la production de chaleur par énergie solaire, selon les tirincipes énoncés dans la partie description du brevet principal n 80 05971 du 14 mars 80. DESCRIPTION
The present invention relates to the production of heat by solar energy, according to the principles stated in the description part of main patent n 80 05971 of March 14, 80.
Les capteurs solaires souples présentés peuvent souffrir de quelques lacunes. Ainsi, il v a des déperditions thermiques à travers la paroi de transmission (film transparent). D'autre part, la résistance mécanique faible de l'ensemble peut compromet -tre la durabilité du produit lors de manipulations. The flexible solar collectors presented may suffer from a few shortcomings. Thus, there is heat loss through the transmission wall (transparent film). On the other hand, the low mechanical strength of the assembly can compromise the durability of the product during handling.
De plus, il est parfois nécessaire d'améliorer au maxi -rnum les échanges thermiques entre le capteur et le milieu à chauffer, lorsque ceux-ci sont plcés en contact direct. Enfin, certaines applications, originales tant par leur technique que par leur forme, nécessitent une protection industrielle avant d'être commercialisées. In addition, it is sometimes necessary to improve the maximum heat exchange between the sensor and the medium to be heated, when these are plcced in direct contact. Finally, certain applications, original both in their technique and in their form, require industrial protection before being marketed.
Les perfectionnetnents décrits ci-dessous apportent des solutions: - au problème de la durabilité de l'ensenole, par l'incorporation d'un sqelette résistant clés la confection du produit; - au problème des déperditions, par utilisation d'une paroi de transmissiontransparente, du type alvéolaire, présentant donc des performances chauffantes accrues par une meilleure isolation. The improvements described below provide solutions: - to the problem of the durability of the Ensoleole, by the incorporation of a resistant sqelette key in the making of the product; - the problem of heat losses, by using a transparent transmission wall, of the cellular type, therefore having increased heating performance by better insulation.
En outre, l'utilisation d'un tel système amélioré pour chauffer l'eau d'une piscine ou d'un réservoir présente le double intérêt de fixer le capteur par flottaison (ce qui supprime les sunports), et d'empêcher la pollution des eaux (débris, possières, etc...) par formation d'un écran ( la surface. Dans ce dernier cas en plus, le film noir cumule les fonctions d'élément absorbeur d'énergie pour le capteur, et d'écran aux rayonnements solaires empêchant ainsi la formation d'algues ou de mousses dans l'eau par supnression cie la photosynthèse. In addition, the use of such an improved system for heating the water of a swimming pool or of a reservoir has the double advantage of fixing the sensor by flotation (which eliminates sunports), and of preventing pollution. water (debris, possessions, etc ...) by forming a screen (the surface. In the latter case in addition, the black film combines the functions of energy absorbing element for the sensor, and screen to solar radiation thus preventing the formation of algae or mosses in water by supnression like photosynthesis.
Les perfectionnements apportés ici seront réalisés de la manière suivante: - La résistance naturelle sera améliorée par introduction de cables en métal ou en plastique, dans des plis formés à cet effet dans une des membranes plastiques (noire ou transparente), du capteur souple; on peut développer les plis le long des lignes d'assemblage des deux membranes du capteur. The improvements made here will be carried out as follows: - The natural resistance will be improved by the introduction of metal or plastic cables, in folds formed for this purpose in one of the plastic membranes (black or transparent), of the flexible sensor; the folds can be developed along the assembly lines of the two membranes of the sensor.
- Les déperditions thermiques dues au film transparent, même dans une utilisation directe sur le milieu à chauffer, seront réduites par utilisation, en lieu et place d'un film homogène mince servant de paroi de transmission, d'une membrane à structure alvéolaire qui présente, en plus de ses caractéristiques de transparence à la lumière visible et d'opacité aux infrarouges, des propriétés isolantes dues à la présence de bulles d'air en cellules fermées. On utilisera, par exemple, des membranes du type de celles qui sont actuellement fabriquées pour des usages d'emballage.- The heat losses due to the transparent film, even in direct use on the medium to be heated, will be reduced by using, instead of a thin homogeneous film serving as a transmission wall, a membrane with alveolar structure which has , in addition to its characteristics of transparency to visible light and opacity to infrared, insulating properties due to the presence of air bubbles in closed cells. We will use, for example, membranes of the type that are currently manufactured for packaging uses.
- Les échanges thermiques entre le capteur et le milieu à chauffer pourront être facilités par des trous pratiqués dans le film noir, ceci bien entendu lorsque le capteur souple est placé en contact avec le milieu à chauffer. De plus, on peut accélérer le renouvellement du fluide caloporteur par utilisation d'une pompe alimentée de manière classique ou par pile photovoltaïque, - Les géométries particulières, découlant de l'association de la technique et de la forme, développées dans les figures nO 1 à 4 pour les-serres agricoles, permettent d'obtenir des performances chauffantes accrues dans le cas de positions basses du soleil (levant, couchant et hiver), sans provoquer de surchauffe quand le soleil est au zénith, et sans diminuer notablement;;la luminosité journaliére sur les plantes, ce qui nuirait à la photosynthèse de celles-ci.- The heat exchanges between the sensor and the medium to be heated can be facilitated by holes made in the black film, this of course when the flexible sensor is placed in contact with the medium to be heated. In addition, the renewal of the heat transfer fluid can be accelerated by using a pump supplied in a conventional manner or by photovoltaic cell, - The particular geometries, arising from the combination of technique and shape, developed in Figures nO 1 to 4 for agricultural greenhouses, allow to obtain increased heating performances in the case of low positions of the sun (rising, setting and winter), without causing overheating when the sun is at its zenith, and without significantly decreasing ;; daily luminosity on plants, which would harm their photosynthesis.
- La géométrie particulière développée dans les figures n0 8 à 11 pour les capteurs solaires en forme d'outres, permet simplement la réversibilité d'exposition, notament aux positions symétriques du soleil levant et du soleil couchant.- The particular geometry developed in Figures 8 to 11 for the solar collectors in the shape of skins, simply allows the reversibility of exposure, notably in the symmetrical positions of the rising sun and the setting sun.
- La durabilité dans le temps sera prolongée par l'utilisation de plastiques dont la résistance au vieillissement a été augmentée par des adjuvants incorporés dans leur masse ou par tout autre procédé.- Durability over time will be extended by the use of plastics whose resistance to aging has been increased by additives incorporated in their mass or by any other process.
- Les figures 5,6,7 et 12 se rapportent aux resrves d'eau. - Figures 5,6,7 and 12 relate to water reserves.
Les capteurs solaires souples ainsi perfectionnés peuvent servir pour les mêmes utilisations que celles décrites dans le brevet nO 80 05971 avec, en plus, le chauffage des piscines et des réservoirs d'eau, en faisant flotter le film plastique à leur surface. Dans ce cas, le film noir du capteur baigne dans le milieu liquide et peut, à la limite, être placé sur le fond et sur le pourtour du bassin. The flexible solar collectors thus perfected can be used for the same uses as those described in patent No. 80 05971 with, in addition, heating swimming pools and water tanks, by floating the plastic film on their surface. In this case, the black film of the sensor is immersed in the liquid medium and can, ultimately, be placed on the bottom and around the basin.
Ils peuvent autre utilisés, dans l'agriculture, pour la production d'eau tiède à des fins d'arrosage ou pour l'augmen -tation des performances actuelles des serres. They can also be used in agriculture for the production of lukewarm water for watering purposes or for increasing the current performance of greenhouses.
Leur possibilité à servir en même temps de bâches isothermes les rend utilisables pour tous les milieux qu'ils enveloppent, par exemple: - du béton coulé en hiver à la montagne; - de l'eau ou de l'air; - des denrées agricoles ou tout autre produit ou matériel (véhicules séjournant à la montagne par exemple) craignant le froid; etc... Their possibility of being used at the same time as insulated tarpaulins makes them usable for all the environments which they envelop, for example: - concrete poured in winter in the mountains; - water or air; - agricultural products or any other product or material (vehicles staying in the mountains for example) fearing the cold; etc ...
