Description
La présente invention concerne un dispositif pour drainer de l'eau froide selon une cellule thermodynamique afin d'extraire un condensat d'eau présent dans l'air.The present invention relates to a device for draining cold water according to a thermodynamic cell in order to extract a water condensate present in the air.
Traditionnellement, les systèmes pour extraire l'eau de l'air par condensation passive utilisent des filets par temps de brouillard, ou encore des revêtements spéciaux sur des toitures pour concentrer la vapeur d'eau comme la rosée sur les fleurs au matin. D'autres systèmes utilisent un processus de ventilation suspendu sur un tube enterré de sorte àinsuffler l'air chaud de la surface vers la base du tuyau refroidie par le sous-sol provoquant un choc thermique qui produit de la condensation. Ces systèmes passifs ont peu de rendement, car ils sont dépendant des phénomènes naturels en particulier et de la météo en général. Les systèmes de condensation active eux fonctionnent par l’électricité selon des condenseurs et des compresseurs énergivores qui nécessitent des infrastructures de production d’électricité conséquentes quand les besoins sont majoritairement dans des localités sans infrastructures.Traditionally, systems for extracting water from the air by passive condensation use nets in foggy weather, or special coatings on roofs to concentrate water vapor such as dew on flowers in the morning. Other systems use a ventilation process suspended on a buried tube so as to blow the hot air from the surface towards the base of the pipe cooled by the basement causing a thermal shock which produces condensation. These passive systems have little performance, because they are dependent on natural phenomena in particular and the weather in general. Active condensation systems operate using electricity using energy-intensive condensers and compressors that require substantial electricity production infrastructure when the needs are mainly in localities without infrastructure.
Le dispositif selon l'invention permet de remédier à ces inconvenants. Il comporte une plaque rectangulaire en plastique souple à l'intérieur de laquelle deux plaques d'aluminium de formes hexagonales sont maintenues l'une contre l'autre par la pression due à l'extraction de l'air faite dans la plaque en plastique. Ces plaques d'aluminium sont faites de couches de feuilles d'aluminium maintenues par adhérences les unes contre les autres par une substance grasse. Une couche de tissu géosynthétique de même forme que les plaques d'aluminium mais de dimension inférieure est placée entre les deux plaques d'aluminium. Les sommets opposés de la plaque d'aluminium sont colinéaires avec les bords des largeurs de la plaque en plastique souple permettant de créer deux ouvertures, au-dessus et en dessous qui en fait une poche plane. Ces deux ouvertures donnent accès à la couche de tissu géosynthétique au milieu. Deux petits tubes en plastiques sont soudés au-dessus et en dessous à l’intérieur des plaques d'aluminium débouchant sur la couche de tissu géosynthétique permettant d'obtenir une unique entrée et une unique sortie vers celle-ci. L'orifice du tube au-dessus est inférieur à celui du tube en dessous. La partie du tube soudé à l'intérieur des plaques d'aluminium, en dessous de celles-ci, comporte des trous sur ses contours afin de drainer le liquide infiltré dans le tube au-dessus passant par la couche de tissu géosynthétique à l'intérieure.The device according to the invention makes it possible to remedy these drawbacks. It comprises a rectangular flexible plastic plate inside which two aluminum plates of hexagonal shapes are held against each other by the pressure due to the extraction of the air made in the plastic plate. These aluminum plates are made of layers of aluminum sheets held by adhesions against each other by a fatty substance. A layer of geosynthetic fabric of the same shape as the aluminum plates but of a smaller dimension is placed between the two aluminum plates. The opposite vertices of the aluminum plate are collinear with the edges of the widths of the flexible plastic plate allowing two openings to be created, above and below which makes a flat pocket. These two openings give access to the layer of geosynthetic fabric in the middle. Two small plastic tubes are welded above and below inside the aluminum plates leading to the layer of geosynthetic fabric to obtain a single entrance and a single exit towards it. The orifice of the tube above is smaller than that of the tube below. The part of the tube welded inside the aluminum plates, below these, has holes on its contours in order to drain the liquid seeping into the tube above passing through the layer of geosynthetic fabric at the interior.
Ainsi, lorsque l'on fait coulé une petite quantité d'eau froide par le tube du dessus, le tissu géosynthétique draine cette eau sur toute sa surface créant une adhérence avec toute la surface des plaques d'aluminium qui, par leurThus, when a small quantity of cold water is run through the top tube, the geosynthetic fabric drains this water over its entire surface, creating adhesion with the entire surface of the aluminum plates which, by their
conductivité thermique, se refroidissent tout en conservant la température du tissu géosynthétique bien après le passage de l'eau froide, ce qui provoque la formation de condensat au-dessus de la plaque en plastique souple tout enthermal conductivity, cool while retaining geosynthetic fabric temperature long after the cold water has passed, causing condensate to form on top of the flexible plastic plate while
permettant de préserver la température de l'eau froide en circulation dans la cellule selon des cycles.maintaining the temperature of the cold water circulating in the cell according to cycles.
Le dispositif multiplié selon ce procédé permet d'obtenir une grande quantité de condensat avec une petite quantité d'eau froide.The device multiplied by this method makes it possible to obtain a large amount of condensate with a small amount of cold water.
Selon des modes particuliers de réalisation:According to particular embodiments:
- des feuilles d'aluminium maintenues les unes contre les autrespar une substance grasse peuvent former des plaques d'aluminium de formes hexagonales.- aluminum sheets held together by a fatty substance can form hexagonal aluminum plates.
- une couche de tissu géosynthétique de forme hexagonale, mais de taille inférieure peut être placée au milieu de deux plaques d'aluminium.- a layer of geosynthetic fabric of hexagonal shape, but of smaller size can be placed in the middle of two aluminum plates.
-les deux plaques d'aluminium peuvent être maintenues l'une contre l'autre avec la couche de tissu géosynthétique au centre dans une plaque rectangulaire en plastique souple grâce à une plastifieuse.- the two aluminum plates can be held against each other with the geosynthetic fabric layer in the center in a rectangular flexible plastic plate thanks to a laminator.
- les sommets de ces feuilles en aluminium peuvent être colinéaires aux largeurs de la plaque en plastique souple.- the vertices of these aluminum sheets can be collinear with the widths of the flexible plastic plate.
- une ouverture peut être faite dans chaque sommet des feuilles d'aluminium en les écartant à l'endroit ou celles-ci sont colinéaires aux bords des largeurs de la plaque en plastique.- An opening can be made in each vertex of the aluminum sheets by spreading them where they are collinear with the edges of the widths of the plastic plate.
- un tube débouchant sur la couche de tissu géosynthétique peut être soudé dans chaque ouverture faite au sommet des plaques aluminium.- a tube opening onto the layer of geosynthetic fabric can be welded into each opening made at the top of the aluminum plates.
- l'orifice du tube au dessus peut être inférieure à l'orifice du tube en dessous.- the orifice of the tube above can be smaller than the orifice of the tube below.
- la partie du tube soudé à l'intérieur des plaques d'aluminium, en dessous, peut comporter des trous sur ces contours pour drainer l'eau issu de la couche de tissu géosynthétique lorsque celle-ci reçoit de l'eau à partir du tube au dessus.- the part of the welded tube inside the aluminum plates, underneath, can have holes on these contours to drain the water from the layer of geosynthetic fabric when the latter receives water from the tube above.

Les plaques en aluminium (5) étant de forme hexagonale leurs sommets colinéaires aux largeurs de la plaque en plastique (2) empêchent que le film plastique qui compose la plaque en plastique soit scellé à cet endroit, ce quiSince the aluminum plates (5) are hexagonal in shape, their vertices collinear with the widths of the plastic plate (2) prevent the plastic film that makes up the plastic plate from being sealed at this point, which
permet de créer des ouvertures de 1 cm environ sur chaque largeur de la plaque en plastique (2) ainsi que dans les plaques en aluminium (5).makes it possible to create openings of approximately 1 cm on each width of the plastic plate (2) as well as in the aluminum plates (5).
