Description
CHAUFFAGE SOLAIRE SOLAR HEATING
La présente invention concerne un chauffage solaire destiné notamment au chauffage de l'eau des piscines. LeThe present invention relates to a solar heating intended in particular for heating water pools. The
Chauffage solaire selon l'invention comprend au moins un tuyau spirale, souple et extensible enclos en tout ou partie dans une enveloppe souple.Solar heating according to the invention comprises at least one spiral hose, flexible and extensible encircled in whole or part in a flexible envelope.
Il est courant de chauffer de l'eau en la faisant circuler dans un circuit exposé au rayonnement solaire. Si cette technique peut servir pour le chauffage de l'eau chaude sanitaire, elle est particulièrement efficace pour le chauffage de l'eau des piscines. En effet, les piscines sont habituellement utilisées lors des journées de fort ensoleillement .It is common to heat water by circulating it in a circuit exposed to solar radiation. If this technique can be used for heating domestic hot water, it is particularly effective for heating swimming pool water. Indeed, swimming pools are usually used on days of strong sunshine.
Afin d'obtenir le meilleur rendement possible, il est nécessaire d'avoir une surface d'exposition au rayonnement solaire importante. Ainsi, les modèles les plus courants de chauffage solaire pour piscine comprennent une nappe plane dans laquelle circule l'eau à chauffer. Ces nappes, pouvant atteindre une surface équivalente aux deux tiers de la surface de la piscine, sont particulièrement encombrantes. En effet, elles sont monoblocs et relativement rigides. Le problème lié à l'encombrement est particulièrement prégnant dans le cas des chauffages pour piscines qui ne sont utilisés que quelques mois par an et doivent être stockés le reste du temps. De plus, le volume important de ces produits rend difficile leur présentation dans les linéaires des commerces et leur transport du lieu de production au lieu de commercialisation.In order to obtain the best possible yield, it is necessary to have a large area of exposure to solar radiation. Thus, the most common models of solar pool heating include a flat sheet in which circulates the water to be heated. These sheets, which can reach an area equivalent to two thirds of the surface of the pool, are particularly bulky. Indeed, they are monobloc and relatively rigid. The congestion problem is particularly significant in the case of swimming pool heaters which are only used for a few months a year and must be stored the rest of the time. In addition, the large volume of these products makes it difficult to present them in the shelves of businesses and their transportation from the place of production to the place of sale.
Un autre inconvénient lié à cette structure et qu' il faut remplacer la nappe dans son intégralité si elle est endommagée (e.g. déchirement, percement...) .Another disadvantage related to this structure and that it is necessary to replace the entire ply if it is damaged (e.g. tearing, drilling ...).
La présente invention résout les problèmes liés aux
chauffages solaires de l'art antérieur. La présente invention propose un chauffage solaire dont toutes les pièces peuvent être facilement et rapidement assemblées, séparées et/ou remplacées. De plus, la présente invention propose un chauffage solaire dont l'encombrement est fortement réduit que ce soit lors de son utilisation ou lors de son stockage pendant les périodes où il n'est pas utilisé.The present invention solves the problems associated with solar heaters of the prior art. The present invention provides solar heating which all parts can be easily and quickly assembled, separated and / or replaced. In addition, the present invention provides solar heating whose size is greatly reduced either during use or during storage during periods when it is not used.
Ainsi, la présente invention concerne un chauffage solaire destiné à chauffer un liquide caloporteur comprenant au moins un tuyau dans lequel ledit fluide caloporteur peut circuler remarquable en ce que ledit tuyau est spirale, souple et extensible et en ce qu'il est enclos en tout ou partie dans une enveloppe souple. Ce chauffage fonctionne sous l'effet du soleil par l'effet de serre appliquée à l'air présent dans l'enveloppe souple. L'énergie est ensuite communiquée au liquide (eau) transitant à l'intérieur du tuyau spirale.Thus, the present invention relates to solar heating for heating a heat transfer liquid comprising at least one pipe in which said heat transfer fluid can circulate remarkable in that said pipe is spiral, flexible and extensible and that it is enclosed in all or part in a flexible envelope. This heating works under the effect of the sun by the greenhouse effect applied to the air present in the flexible envelope. The energy is then communicated to the liquid (water) passing inside the spiral pipe.
Dans le cadre de la présente invention, le terme « liquide caloporteur » fait référence à tout liquide capable de stocker des calories et de les rendre en fonction de la température de l'environnement dans lequel réside ledit liquide. Selon un mode de réalisation préféré de l'invention, ledit liquide caloporteur est de l'eau. Dans le cadre de la présente invention, le terme « spirale » signifie qu'au repos, le tuyau, compris dans le chauffage solaire, est sur tout ou partie de sa longueur sous la forme d'un solénoïde. Le diamètre dudit solénoïde peut varier entre deux points du solénoïde. Selon un mode de réalisation préféré de l'invention, ledit solénoïde à un diamètre compris entre 2 et 45 cm, de façon encore plus préféré compris entre 5 et 25 cm et de façon tout à fait préféré entre 7 et 11 cm.In the context of the present invention, the term "heat-transfer liquid" refers to any liquid capable of storing calories and rendering them as a function of the temperature of the environment in which said liquid resides. According to a preferred embodiment of the invention, said heat transfer liquid is water. In the context of the present invention, the term "spiral" means that at rest, the pipe, included in the solar heating, is over all or part of its length in the form of a solenoid. The diameter of said solenoid may vary between two points of the solenoid. According to a preferred embodiment of the invention, said solenoid has a diameter of between 2 and 45 cm, even more preferably between 5 and 25 cm and quite preferably between 7 and 11 cm.
Dans le cadre de la présente invention, le terme
« souple » signifie que le tuyau selon l'invention peut être plié sous l'effet d'une force faible (inférieure à 20 N et de préférence inférieure à 10 N) et ce même lorsque ledit tuyau est assemblé au reste des éléments du chauffage solaire selon l'invention.In the context of the present invention, the term "Flexible" means that the pipe according to the invention can be folded under the effect of a weak force (less than 20 N and preferably less than 10 N) and even when said pipe is assembled to the rest of the heating elements solar according to the invention.
Dans le cadre de la présente invention, le terme « extensible » signifie que sous l'effet d'une première force de 25 N appliquée à une des deux extrémités dudit tuyau spirale et d'une seconde force de 25 N, en direction opposée à la première force, appliquée à l'autre extrémité dudit tuyau spirale, le solénoïde se déforme et la distance entre les deux extrémités dudit tuyau va augmenter d' au moins 100%.In the context of the present invention, the term "expandable" means that under the effect of a first force of 25 N applied to one of the two ends of said spiral pipe and a second force of 25 N, in the opposite direction to the first force, applied to the other end of said spiral pipe, the solenoid deforms and the distance between the two ends of said pipe will increase by at least 100%.
Selon un mode de réalisation préféré, le tuyau spirale, souple et extensible compris dans le chauffage solaire selon l'invention n'est pas enroulé autour d'une âme centrale.According to a preferred embodiment, the spiral hose, flexible and extensible included in the solar heating according to the invention is not wrapped around a central core.
Selon un autre mode de réalisation préféré, le tuyau spirale, souple et extensible compris dans le chauffage solaire selon l'invention n'est pas enclos en tout ou partie dans une enveloppe totalement ou partiellement rigide. Contrairement aux chauffages solaires de l'art antérieur, l'utilisation d'une enveloppe souple permet de réduire le volume avant montage du chauffage solaire selon l' invention.According to another preferred embodiment, the spiral hose, flexible and extensible included in the solar heating according to the invention is not enclosed in whole or part in a totally or partially rigid envelope. Unlike solar heaters of the prior art, the use of a flexible envelope reduces the volume before mounting solar heating according to the invention.
Il est connu de l'homme du métier des chauffages solaires comprenant des tuyaux spirales non extensibles et/ou non souples, c'est notamment le cas des chauffages solaires décrit dans la demande FR2385054A1, EP0095135B1, CA2150750AA. Dans ce type de chauffage, contrairement au chauffage solaire de l'invention, le tuyau spirale n'est pas extensible, car les différentes spires du solénoïde sont solidaires les unes des autres et/ou car le solénoïde est enclos et/ou solidaire d'une structure solide.
- A -It is known to those skilled in the art solar heaters comprising non-extensible and / or non-flexible spiral hoses, this is particularly the case of solar heaters described in the application FR2385054A1, EP0095135B1, CA2150750AA. In this type of heating, unlike the solar heating of the invention, the spiral pipe is not extensible, because the different turns of the solenoid are integral with each other and / or because the solenoid is enclosed and / or secured to a solid structure. - AT -
Le tuyau spirale, souple et extensible compris dans le chauffage solaire de l'invention est constitué d'une matière choisi dans le groupe comprenant le PE, le HDPE, le LDPE, le PP, le PP-R, le PVC, l'EPDM, le PU et l'EVA. Selon un mode de réalisation préféré de l'invention, ledit tuyau spirale, souple et extensible est en PE.The spiral hose, flexible and extensible included in the solar heating of the invention consists of a material selected from the group consisting of PE, HDPE, LDPE, PP, PP-R, PVC, EPDM , PU and EVA. According to a preferred embodiment of the invention, said spiral hose, flexible and extensible is PE.
L'enveloppe souple permet d'optimiser 1 ' échauffement du gaz se trouvant dans l'enveloppe. D'autre part, l'enveloppe isole le tuyau des effets directs du vent. Elle permet de concentrer également la chaleur et d'obtenir des montées en températures plus rapides (par effet de serre) .The flexible envelope optimizes the heating of the gas in the envelope. On the other hand, the envelope isolates the pipe from the direct effects of the wind. It also allows heat to be concentrated and temperatures rise faster (by the greenhouse effect).
Cette enveloppe souple peut enclore tout ou partie dudit tuyau et préférentiellement au moins la totalité de la portion dudit tuyau ayant la forme d'un solénoïde. Selon un mode de réalisation encore plus préféré de l'invention, les deux extrémités dudit tuyaux ne sont pas encloses dans ladite enveloppe souple.This flexible envelope can enclose all or part of said pipe and preferably at least the entire portion of said pipe having the shape of a solenoid. According to an even more preferred embodiment of the invention, the two ends of said pipes are not enclosed in said flexible envelope.
Avant assemblage au chauffage solaire selon l'invention, l'enveloppe souple peut être sous la forme d'un cylindre ouvert à ses deux extrémités. Selon un mode de réalisation préféré, ladite enveloppe souple, sous la forme d'un tube, est associée sur tout ou partie de sa longueur à un ressort hélicoïdal. Par « associé », on entend signifier que la surface interne et/ou externe dudit ressort hélicoïdal est recouverte par ladite enveloppe souple. Selon un mode de réalisation encore plus préféré, ledit ressort hélicoïdal est fixé en au moins deux points point à ladite enveloppe souple. Selon un mode de réalisation tout à fait préféré lesdits points de fixations sont situés à proximité des extrémités de ladite hélice hélicoïdale et de ladite enveloppe souple en forme de tube.Before assembly with solar heating according to the invention, the flexible envelope may be in the form of a cylinder open at both ends. According to a preferred embodiment, said flexible envelope, in the form of a tube, is associated over all or part of its length with a helical spring. "Associate" means that the inner and / or outer surface of said coil spring is covered by said flexible envelope. According to an even more preferred embodiment, said helical spring is fixed in at least two point points to said flexible envelope. According to a most preferred embodiment, said attachment points are located near the ends of said helical helix and said flexible envelope in the form of a tube.
Le ressort hélicoïdal présente l'avantage de pouvoir être compressé avant l'installation du capteur et ainsi d'occuper un faible espace de stockage. Lors de la mise en
place du chauffage solaire selon l'invention, il est totalement ou partiellement détendu et permet d'assurer automatiquement la tension de l'enveloppe souple. Cette tension permet d'optimiser la surface utile de ladite enveloppe souple et de maintenir un volume d' air à l'intérieur de ladite enveloppe.The coil spring has the advantage of being compressed before installation of the sensor and thus occupy a small storage space. When setting Instead of solar heating according to the invention, it is totally or partially relaxed and automatically ensures the tension of the flexible envelope. This tension makes it possible to optimize the useful area of said flexible envelope and to maintain a volume of air inside said envelope.
Ledit ressort hélicoïdal peut également permettre la mise en tension dudit tuyau lorsque celui-ci est fixé audit ressort. Selon un autre mode de réalisation préféré de l'invention, ladite enveloppe souple est une structure gonflable ayant sensiblement la forme d'un cylindre creux. Par souci de clarté, il est précisé que par cylindre creux on entend désigner un cylindre comprenant un évidement longitudinal ouvert aux deux bases dudit cylindre. L'axe dudit évidement longitudinal peut être confondu à l'axe dudit cylindre ou peut être excentré par rapport à celui- ci. L' évidemment longitudinal peut recevoir un ou plusieurs tuyaux spirales qui est ainsi enclos dans ladite structure gonflable.Said coil spring can also allow the tensioning of said pipe when it is attached to said spring. According to another preferred embodiment of the invention, said flexible envelope is an inflatable structure having substantially the shape of a hollow cylinder. For the sake of clarity, it is specified that hollow cylinder means a cylinder comprising a longitudinal recess open to the two bases of said cylinder. The axis of said longitudinal recess may be coincident with the axis of said cylinder or may be eccentric with respect thereto. The longitudinal recess can receive one or more spiral pipes which is thus enclosed in said inflatable structure.
Cette enveloppe souple peut également avoir la forme d'un sac. Les ouvertures de ladite enveloppe souple peuvent comprendre en outre un moyen permettant de fermer ladite enveloppe souple autour dudit tuyau. Ces moyens de fermeture peuvent être sous la forme d'une cordelette passant dans un ourlet au niveau au niveau de l'ouverture. Cet ourlet est ouvert sur l'extérieur en au moins un point, ce qui permet de faire sortir les deux extrémités de ladite cordelette. La cordelette peut ainsi servir pour serrer l'ouverture de l'enveloppe souple autour du tuyau. Ce moyen de fermeture peut également être une zone élastique s' étendant sur la circonférence de ladite enveloppe souple, ladite zone élastique ayant au repos un diamètre égal ou inférieur à celui du tuyau.
La couleur et la matière constituant l'enveloppe souple du chauffage solaire selon l'invention ont une incidence sur l'efficacité du dispositif. Ainsi, selon un mode de réalisation préféré de l'invention, l'enveloppe souple selon l'invention sera constituée d'un film de PE, PU, PP, EVA, PVC, EPDM, POLEYESTER, ELASTHANE, ACRYLIQUE, CHLOROFIB RES, POLYAMIDE. Ce film pourra avoir une épaisseur comprise entre 0.01mm et 3mm, et préférentiellement comprise entre 0.05mm et 0.15mm. Le film peut être transparent, translucide ou opaque, il peut également être coloré. Selon un mode de réalisation préféré, le film constituant l'enveloppe souple est noir et opaque. Selon un autre mode de réalisation préféré, ladite enveloppe souple comporte une portion translucide et une portion noire ou métallisée. Ce type d'enveloppe permet en plaçant la portion translucide au dessus dudit tuyau spirale et la portion noire ou métallisée en dessous dudit tuyau spirale d'accroître l'effet de serre interne et de focaliser le rayonnement solaire sur les parois du tuyau spirale. Selon un mode de réalisation préféré, le chauffage solaire selon l'invention comprend en outre une conduite d'admission comprenant au moins une ouverture à laquelle est connectée une extrémité dudit tuyau spirale, souple et extensible et une conduite de sortie comprenant au moins une ouverture à laquelle est connectée l'autre extrémité dudit tuyau spirale, souple et extensible.This flexible envelope may also be in the form of a bag. The openings of said flexible envelope may further comprise means for closing said flexible envelope around said pipe. These closure means may be in the form of a cord passing through a hem at the level of the opening. This hem is open on the outside in at least one point, which allows to get out both ends of said cord. The cord can thus be used to tighten the opening of the flexible envelope around the pipe. This closure means may also be an elastic zone extending over the circumference of said flexible envelope, said elastic zone having at rest a diameter equal to or less than that of the pipe. The color and the material constituting the flexible envelope of the solar heating according to the invention have an effect on the efficiency of the device. Thus, according to a preferred embodiment of the invention, the flexible envelope according to the invention will consist of a film of PE, PU, PP, EVA, PVC, EPDM, POLEYESTER, ELASTHANE, ACRYLIC, CHLOROFIB RES, POLYAMIDE. . This film may have a thickness of between 0.01 mm and 3 mm, and preferably between 0.05 mm and 0.15 mm. The film can be transparent, translucent or opaque, it can also be colored. According to a preferred embodiment, the film constituting the flexible envelope is black and opaque. According to another preferred embodiment, said flexible envelope comprises a translucent portion and a black or metallized portion. This type of envelope allows by placing the translucent portion above said spiral pipe and the black or metallized portion below said spiral pipe to increase the internal greenhouse effect and to focus the solar radiation on the walls of the spiral pipe.
