Description
La présente invention est du domaine des locaux fonctionnels et elle a plus particulièrement pour objet un dispositif à structure de bâtiment destiné à sécher un matériau ou un produit humide ; l'invention est également du domaine des capteurs solaires. The present invention is in the field of functional premises and it relates more particularly to a device with a building structure intended for drying a wet material or product; the invention is also in the field of solar collectors.
On connait aujourd'hui de nombreuses applications de capteurs de l'énergie solaire pour produire de la chaleur destinée au chauffage des locaux les capteurs peuvent se présenter soit comme des dispositifs distincts de la structure du bâtiment, par exemple rapportés sur la toiture, soit incoporés à la structure pour en constituer certaines parties, de façades exposées au soleil par exemple. Many applications of solar energy collectors are known today for producing heat intended for space heating. The collectors can be presented either as devices distinct from the structure of the building, for example attached to the roof, or incorporated to the structure to constitute certain parts, of facades exposed to the sun for example.
En matière de séchoir à bois, on connait des hangars à murs largement aérés, ou encore des enceintes closes dans lesquelles de l'air chauffé par un générateur thermique, est propulsé. In terms of wood driers, there are known hangars with widely ventilated walls, or closed enclosures in which air heated by a heat generator is propelled.
L'idée-mère de la présente invention est de combiner certaines des techniques précitées en les adaptant les unes aux autres pour aboutir à une enceinte de séchage fonctionnant pratiquement sans apport d'énergie. The main idea of the present invention is to combine some of the aforementioned techniques by adapting them to each other to result in a drying enclosure operating practically without any energy supply.
Selon la présente invention, un dispositif, dit séchoir, destiné à sécher un matériau ou un produit humide est caractérisé d'une manière générale en ce qu'il se compose essentiellement d'une enceinte de bâtiment dont quatre des cinq faces visibles sont revêtues sur la quasi-totalité de leur surface de capteurs solaires, ladite enceinte formant le volume du séchoir, et d'une masse thermique intermédiaire destinée à être réchauffée pendant le jour par ]'action des capteurs et à restituer sa chaleur au séchoir pendant la nuit. According to the present invention, a device, known as a dryer, intended for drying a wet material or product is generally characterized in that it essentially consists of a building enclosure of which four of the five visible faces are coated on almost all of their surface of solar collectors, said enclosure forming the volume of the dryer, and an intermediate thermal mass intended to be heated during the day by the action of the collectors and to restore its heat to the dryer during the night.
Pour des raisons à la fois de prix et de commodités, le fluide caloporteur des capteurs est l'air ; un premier circuit dans lequel i 'air caloporteur peut être mis en circulation forcée par un ventilateur comprend lesdits capteurs d'une part et ladite masse thermi que d'autre part tandis qu'un second circuit d'air comprend ladite masse thermique d'une part et ladite enceinte d'autre part, ledit second circuit pouvant etre soit fermé sur lui-meme, soit ouvert sur l'atmosphère. Il résulte des dispositions précitées qu'on a réalisé une enceinte offrant un maximum de surface d'exposition donc d'échange, et que pendant la nuit, l'arrêt de la circulation forcée dans les capteurs évite une déperdition de chaleur par ces derniers, tandis que peut se poursuivre le séchage grâce à la chaleur de ladite masse thermique.Avantageusement, la circulation de l'air dans le second circuit peut, elle aussi, être forcée, par un second ventilateur ; il en résulte la possibilité d'un réglage de l'humidité de l'enceinte. Suivant un mode préféré d'exécution, lesdits premier et second circuits comprennent des tuyaux disposés au voisinage des aretes, côté intérieur, de ladite enceinte, et lesdits premier et second ventilateur sont disposés à l'extérieur de ladite enceinte. For reasons of both price and convenience, the heat transfer fluid of the sensors is air; a first circuit in which the heat transfer air can be forced into circulation by a fan comprises said sensors on the one hand and said thermal mass on the other hand while a second air circuit comprises said thermal mass of a part and said enclosure on the other hand, said second circuit can be either closed on itself, or open to the atmosphere. It follows from the abovementioned provisions that an enclosure has been produced offering a maximum exposure and therefore exchange surface area, and that during the night, the stopping of the forced circulation in the collectors avoids heat loss by the latter, while drying can continue thanks to the heat of said thermal mass. Advantageously, the circulation of air in the second circuit can also be forced, by a second fan; this results in the possibility of adjusting the humidity of the enclosure. According to a preferred embodiment, said first and second circuits comprise pipes arranged in the vicinity of the ridges, on the inside, of said enclosure, and said first and second fans are arranged outside of said enclosure.
Avantageusement encore, le deuxieme circuit, étant un circuit fermé, comprend un condenseur disposé entre l'enceinte et la masse thermique le condenseur est par exemple un serpentin disposé au-dessus d'une gouttière et parcouru par un fluide froid tel que fréon d'un groupe frigorifique ou eau froide d'un réseau il en résulte une encore meilleure possibilité de régulation d'hygrométrie de l'enceinte. de séchoir. Advantageously also, the second circuit, being a closed circuit, comprises a condenser disposed between the enclosure and the thermal mass, the condenser is for example a coil arranged above a gutter and traversed by a cold fluid such as freon a refrigeration unit or cold water from a network this results in an even better possibility of regulating the humidity of the enclosure. dryer.
Suivant une disposition particulière de l'invention, la masse thermique est constituée par un amas de galets disposés au-dessous du plancher de ladite enceinte. On notera que les galets ne sont cités qu'à titre d'exemples préférés mais qu'ils pourraient être remplacés par d'autres matériaux ayant des propriétés équivalentes voire même meilleure s'il n'y avait lieu de prendre en compte l'inconvénient du coût par exemple des sels eutectiques, des bonbonnes métalliques remplies d'eau, des masses métalliques, etc... According to a particular arrangement of the invention, the thermal mass consists of a heap of rollers arranged below the floor of said enclosure. It will be noted that the rollers are only cited as preferred examples but that they could be replaced by other materials having equivalent or even better properties if it were not necessary to take into account the disadvantage the cost for example of eutectic salts, metal cylinders filled with water, metallic masses, etc.
Suivant une caractéristique par ticulière de l'invention, chaque capteur est constitué par un empilement d'éléments reliés entre eux à leur périphérie par un joint de scellement, l'empilement comprenant, de l'extérieur vers l'intérieur, une vitre de verre , un cadre en profilé d'aluminium, une plaque absorbante ou absorbeur, une juxtaposition de cadres en profilé d'aluminium orientés verticalement, une seconde juxtaposition de cadres en aluminium orientés horizontalement, une plaque de mousse de polyuréthane et une plaque d'aluminium. According to a particular feature of the invention, each sensor is constituted by a stack of elements connected together at their periphery by a sealing joint, the stack comprising, from the outside to the inside, a glass pane , an aluminum profile frame, an absorbent or absorber plate, a juxtaposition of vertically oriented aluminum profile frames, a second juxtaposition of horizontally oriented aluminum frames, a polyurethane foam plate and an aluminum plate.
Revenant à la structure générale du bâtiment de l'enceinte, sa face formant toiture, dite quatrième, est inclinée sur l'horizontale salivant un angle compris entre 100 et 300 et comporte des capteurs ; sa face, dite cinquième, située au-dessous de l'arête la plus élevée de la toiture comporte, sur la quasi-totalité de sa largeur, une porte d'accès de chargement et de déchargement de ladite enceinte ; enfin la masse thermique est contenue dans une auge maçonnée à plan rectangulaire, formant assise pour ledit bâtiment, les parois latérales et de fond de ladite auge comportant une couche d'isolant thermique, sa paroi supérieure formant le plancher de ladite enceinte. Returning to the general structure of the enclosure building, its roofing face, called the fourth face, is inclined to the horizontal, salivating an angle between 100 and 300 and includes sensors; its so-called fifth face, located below the highest edge of the roof comprises, over almost its entire width, an access door for loading and unloading said enclosure; finally, the thermal mass is contained in a masonry trough with a rectangular plane, forming a seat for said building, the side and bottom walls of said trough comprising a layer of thermal insulation, its upper wall forming the floor of said enclosure.

Sur la fig.1, un séchoir de l'invention est composé essentiellement d'une enceinte de bâtiment 1 reposant sur un socle maçonné 2 ; toutes les faces du bâtiment à l'exception de la face 5 sont revêtues de capteurs solaires tels que 6 dont on décrira plus loin de façon plus détaillée la structure ; ainsi une face latérale 3 de forme trapézoidale comporte des capteurs sur la quasi-totalité de sa largeur ; ainsi encore la face 4 formant la toiture est revetue de capteurs sur la totalité de sa surface.On remarque que le bâtiment est de forme prismatique, la face 5, disposé au-dessous de l'arête 7 la plus élevée de la toiture, étant la plus grande de ses faces latérales et étant orientée vers le Nord, cette face 5, dite cinquième, comporte sur la quasi- totalité de sa largeur une porte 8 à double battant. In fig.1, a dryer of the invention consists essentially of a building enclosure 1 resting on a masonry base 2; all the faces of the building with the exception of face 5 are coated with solar collectors such as 6, the structure of which will be described in more detail below; thus a lateral face 3 of trapezoidal shape comprises sensors over almost its entire width; thus again the face 4 forming the roof is coated with sensors over its entire surface. It is noted that the building is of prismatic shape, the face 5, arranged below the highest ridge 7 of the roof, being the largest of its lateral faces and being oriented towards the North, this so-called fifth face 5 comprises over almost its entire width a door 8 with a double leaf.
Suivant un mode préféré de réalisation de l'invention, le fluide caloporteur effectuant le transfert de la chaleur depuis les capteurs solaires est constitué par de l'air. According to a preferred embodiment of the invention, the heat transfer fluid effecting the transfer of heat from the solar collectors consists of air.
Sur la fig.2, on a schématisé un premier circuit Il d'air comprenant des conduites 11, l'ensemble des capteurs solaires 6 et l'ambiance d'une masse thermique 13 ; on a schématisé également un second circuit d'air comprenant des conduites telles que 12, le volume intérieur de l'enceinte l et la même masse thermique 13 l'ambiance de la masse thermique 13 est donc une partie de circuit commune au circuit 11 et 12. In fig.2, a first air circuit II has been shown diagrammatically comprising pipes 11, all of the solar collectors 6 and the atmosphere of a thermal mass 13; a second air circuit is also shown diagrammatically comprising pipes such as 12, the interior volume of the enclosure l and the same thermal mass 13 the atmosphere of the thermal mass 13 is therefore a part of the circuit common to the circuit 11 and 12.
La circulation d'air dans les circuits 11 et 12 peut être avantageusement forcée par des ventilateurs ou turbines tels que respectivement -15 et 16 pour chacun des circuits ; les ventilateurs sont placés sous la dépendance de moyens de commande et de régulation respectivement 17 et 18 ; on a encore schématisé par 19 des moyens déshumidificateurs, condenseurs par exemple, placés à la sortie de l'enceinte sur le circuit 12 ; ces moyens 19 peuvent être soit en série dans ce circuit soit y être en parallèle, dans ce cas ils peuvent comporter un ventilateur 20 commandé par un hygrostat 21 ; cette dernière disposition permet un réglage plus souple de l'humidité dans l'enceinte. The circulation of air in circuits 11 and 12 can advantageously be forced by fans or turbines such as -15 and 16 respectively for each of the circuits; the fans are placed under the dependence of control and regulation means 17 and 18 respectively; schematized by 19 dehumidifying means, condensers for example, placed at the outlet of the enclosure on the circuit 12; these means 19 can either be in series in this circuit or be there in parallel, in which case they can comprise a fan 20 controlled by a hygrostat 21; this latter arrangement allows a more flexible adjustment of the humidity in the enclosure.
Les moyens de commande 17 du ventilateur 15, dit premier, forçant la circulation dans le premier circuit comprennent essentiellement un thermomètree différentiel captant la différence de température entre un capteur 6 et la masse thermique 13, pour mettre en marche le ventilateur 15 lorsque cette différence positive est suffisante. Ces moyens de commande 17 pourraient aussi être du type cellule pbotoélectrique pour mettre en marche le ventilateur 15 lorsque l'éclairement est suffisant, avec un thermomètre d'interdiction lorsque, l'éclairement étant suffisant, le froid extérieur est trop vif.Les moyens de commande 18 sont essentiellement des moyens thermométriques et/ou thermométriques différentiels pour mettre en marche le ventilateur 16 lorsque la température dans 1'enceinte chute au-dessous d'un certain seuil alors que celle de la masse thermique est encore assez élevée. The control means 17 of the fan 15, said first, forcing circulation in the first circuit essentially comprises a differential thermometer sensing the temperature difference between a sensor 6 and the thermal mass 13, to start the fan 15 when this positive difference is sufficient. These control means 17 could also be of the pbotoelectric cell type for starting the fan 15 when the lighting is sufficient, with a prohibition thermometer when, the lighting being sufficient, the outside cold is too high. control 18 are essentially differential thermometric and / or thermometric means for switching on the fan 16 when the temperature in the enclosure drops below a certain threshold while that of the thermal mass is still fairly high.
Grâce aux moyens précités, on peut capter un maximum d'énergie solaire, pour des conditions météorologiques données, à la fois à un instant donné et en moyenne sur une période donnée, puisque durant la nuit où l'énergie solaire est absente, il nty a pas à craindre, du fait de l'arrêt de la circulation dans le circuit 11, de refroidissement à travers les capteurs 6. Thanks to the aforementioned means, it is possible to collect a maximum of solar energy, for given meteorological conditions, both at a given instant and on average over a given period, since during the night when solar energy is absent, it nty is not to be feared, due to the stopping of circulation in the circuit 11, of cooling through the sensors 6.
Sur les fig.3,3' et 4, un capteur 6 se compose de l'intérieur vers i 'extérieur d'une vitre 30 de verre, trempé de préférence, de 4 mm d'épaisseur, d'un cadre 31 en profilé d'aluminium de 12 mm d'épaisseur, d'une plaque absorbante, ou absorbeur 32, constitué d'une feuille métallique mince noircie, d'une première juxtaposition de cadres 33 en profilé d'aluminium de 12 mm orientés verticalement, d'une seconde juxtaposition de cadres 34 en profilé d'alumi nium orientés horizontalement, d'une plaque 35 de mousse de polyuréthane et d'une plaque 36 d'aluminium, ces deux dernières plaques étant pourvues le long de leurs petits cotés, inférieur et supérieur, d'une double pluralité d'orifices 37 de passage de l'air contenu entre les cadres juxtaposés 33 à 34.On remarque sur la fig.3' plus particulièrement que les éléments extérieur (vitre) et intérieur (plaque de mousse 35 et d'Aluminium 36) du capteur sont légèrement plus grands en longueur et en largeur que les autres éléments ; il en découle la présence d'un sillon périphérique qui est rempli d'un matériau de scellement 38 tel que polysulfure ou silicone. In Figs. 3,3 'and 4, a sensor 6 is made up from the inside to the outside of a window 30 of glass, preferably toughened, 4 mm thick, of a frame 31 in profile aluminum 12 mm thick, an absorbent plate, or absorber 32, consisting of a thin blackened metal sheet, a first juxtaposition of frames 33 of 12 mm aluminum profile oriented vertically, a second juxtaposition of frames 34 in horizontally oriented aluminum profile, of a plate 35 of polyurethane foam and of an aluminum plate 36, the latter two plates being provided along their short sides, lower and upper , of a double plurality of orifices 37 for the passage of the air contained between the juxtaposed frames 33 to 34. It is noted in FIG. 3 'more particularly that the exterior (glass) and interior (foam plate 35 and Aluminum 36) of the sensor are slightly larger in length and width than the other elements; this results in the presence of a peripheral groove which is filled with a sealing material 38 such as polysulfide or silicone.
Sur les fig.5 et 5a, est montré comment des capteurs tels que 6 sont maintenus dans une ossature de la construction faite de montants 40 et de traverses 41 à l'aide de parcloses 42, et comment l'air chauffé par le capteur est recueilli dans des tubes ajourés, dits collecteurs d'échappement, tels que 43 dont une lumière est disposée en regard de la rangée d'orifices 37 ; des tubes analogues dits collecteurs d'admission, non représenté sur la figure sont disposés à la partie inférieure des capteurs. In Figs. 5 and 5a, is shown how sensors such as 6 are held in a frame of the construction made of uprights 40 and sleepers 41 using glazing beads 42, and how the air heated by the sensor is collected in perforated tubes, called exhaust manifolds, such as 43, a light of which is arranged opposite the row of orifices 37; similar tubes, called intake manifolds, not shown in the figure, are arranged at the bottom of the sensors.
Sur la fig.6, la coupe d'un bâtiment de séchoir suivant le plan A de la fig.1 montre des collecteurs d'échappement tels que 43 disposés au voisinage de la partie la plus élevée des capteurs et des collecteurs d'admission 43' disposés à leur partie inférieure ; ces collecteurs sont en PVC de préférence pour former les deux branches du circuit 11 et on notera qu'en vue d'un encombrement minimal les parties verticales de ces circuits empruntent les angles de l'espace interne de la construction. In Fig. 6, the section through a dryer building along plane A in Fig. 1 shows exhaust manifolds such as 43 arranged in the vicinity of the highest part of the sensors and intake manifolds 43 'arranged at their lower part; these collectors are preferably made of PVC to form the two branches of the circuit 11 and it will be noted that, with a view to minimal bulk, the vertical parts of these circuits take the angles of the internal space of the construction.
Toujours sur la fig.6, il apparait que la masse thermique 13 formée de galets est contenue dans le socle 2 maçonné en auge dont les parois et le fond comportent une couche d'isolant 45 ; les bords supérieurs de l'auge supportent un plancher 46 ; on remarque encore que l'inclinaison de la face 4 de toiture est inclinée à environ 100 sur l'horizontale. Les ventilateurs tels que les ventilateurs 16 sont disposés dans des appentis 47 disposés le long du bord Sud du socle 2 ; la couverture 48 de ces appentis est en tôle galvanisée et sert de réflecteur pour diriger un rayonnement supplémentaire vers les capteurs situés au-dessus d'eux. L'appentis peut également logé un compresseur dans le cas où la condensation est réalisée au moyen d'un groupe frigorifique. Still on FIG. 6, it appears that the thermal mass 13 formed of rollers is contained in the base 2 built into a trough, the walls and bottom of which include an insulating layer 45; the upper edges of the trough support a floor 46; we also note that the inclination of the roof face 4 is inclined at about 100 on the horizontal. The fans such as the fans 16 are arranged in sheds 47 arranged along the southern edge of the base 2; the cover 48 of these lean-tos is made of galvanized sheet metal and serves as a reflector for directing additional radiation towards the sensors situated above them. The lean-to can also house a compressor if the condensation is carried out by means of a refrigeration unit.
Bien que l'on ait décrit et représenté des formes particulières de réalisation de la présente invention, il doit être compris que la portée de celle-ci n'est pas limitée à ces formes mais qu'elle s'étend à toute structure de bâtiment ou d'enceinte de séchage comportant les caractéristiques générales énoncées plus haut. Although particular embodiments of the present invention have been described and shown, it should be understood that the scope thereof is not limited to these forms but that it extends to any building structure or drying enclosure with the general characteristics set out above.
