Abstract

Two concentric porous terracotta tubes of the same length are fixed by pinch-welding covers of the same material and by firing, thus forming two containers (R1,R2). The internal wall of the inner container (R2) is totally enamelled to seal it and prevent liquid osmosis between the two containers. The water in the outer container (R1) transpires through capillary action through its porous external walls, and evaporates there in contact with heat or wind. This evaporation generates cooling by energy transfer from the liquid circumference in the inner container. The device is installed outside under the influence of solar heating or wind, and if the liquid in the container is extracted by pumping it may be ducted to a convector cooler. USE - Transpiration cooling by natural solar energy and wind.

Description

DESCRIPTIO-
GENERATEUR D'EAU FROIDE A ENRAIE NATURELLE
La présente invention concerne un dispositif pour produire de l'eau froide (ou tout autre liquide), en saison chaude, pour alimenter un ventilo-convecteur à l'aide d'énergie naturelle.DESCRIPTIO-
COLD WATER GENERATOR WITH NATURAL ENRAY
The present invention relates to a device for producing cold water (or any other liquid), in the hot season, for supplying a fan coil using natural energy.

Nous connaissons déåà les groupes de préparation de liquide froid à énergie électrique ou minérale. We already know the cold liquid preparation groups with electric or mineral energy.

Le dispositif présenté a pour objet de puiser dans la nature, l'énergie dont il a besoin pour fonctionner: rayonnement solaire, chaleur atmosphérique ou vent. The purpose of the device presented is to draw from nature, the energy it needs to function: solar radiation, atmospheric heat or wind.

I1 se compose en effet d'un récipient tubulaire de terre cuite poreuse que l'on remplit d'eau et qui contient lui-meme un second récipient tubulaire de diamètre inférieur, non poreux, que lton remplit aussi de liquide. It consists in fact of a tubular container of porous terracotta which is filled with water and which itself contains a second tubular container of smaller diameter, non-porous, which is also filled with liquid.

Le dispositif est expose au soleil ou au Vent, l'eau contenue entre le gros et le petit cylindre imbibe la paroi et transpire sur la surface externe du dispositif pour s'y évaporer. Cette vaporisation produit du froid qui par transfert d'énergie va réfrigérer à son tour le liquide qui est contenu dans le récipient tubulaire intérieur. The device is exposed to the sun or to the Wind, the water contained between the large and the small cylinder soaks the wall and transpires on the external surface of the device to evaporate there. This vaporization produces cold which by energy transfer will in turn cool the liquid which is contained in the inner tubular container.

L'étanchéité du récipient tubulaire intérieur, qui peut être en terre cuite émaillée dans sa partie interne par exemple, évite le mélange des deux liquides par phénomène d'osmose et permet ainsi d'utiliser dans celui-ci un liquide réfrigérant autre que de l'eau et surtout, de l'utiliser en circuit fermé comme il est fait pour tout groupe de préparation de liquide froid traditionnel. The tightness of the inner tubular container, which can be made of enameled terracotta in its internal part, for example, avoids mixing of the two liquids by osmosis phenomenon and thus makes it possible to use in it a cooling liquid other than l water and above all, use it in a closed circuit as it is done for any traditional cold liquid preparation group.

I1 s'agit en fait d'une résultanteélaborée du principe de l'alcaraza (qui est une carafe de terre poreuse dans laquelle l'eau se rafraichit par évaporation) qui utilise le fait que l'évaporation d'un liquide produit du froid et que celle-ci est d'autant plus intense quand l'air est sec, plus chaud ou agité par le vent.  It is actually a result of the principle of the alcaraza (which is a carafe of porous earth in which the water cools down by evaporation) which uses the fact that the evaporation of a liquid produces cold and that this is all the more intense when the air is dry, hotter or agitated by the wind.

La régulation de la température du liquide réfrigérant s'effectue donc proportionnellement au climat extérieur dans lequel se trouve le dispositif, en effet, au plus il fait chaud à l'extérieur, au plus le liquide réfrigérant qui alimente le ventilo-convecteur est froid. The temperature of the coolant is therefore regulated in proportion to the outdoor climate in which the device is located, in fact, the warmer it is outside, the cooler the coolant that feeds the fan coil.

Selon des modes particuliers de réalisation, le dispositif est formé de deux tubes de terre cuite poreuse de même nature rendus solidaires par collage de deux disques, supérieur et inférieur, de même nature également; le plus petit tube est traité en étanchéité par émaillage de la totalité de sa paroi intérieure. According to particular embodiments, the device is formed of two porous terracotta tubes of the same kind made integral by bonding two discs, upper and lower, also of the same kind; the smallest tube is treated as a seal by enamelling the entire inner wall.

L'épaisseur de terre cuite formant le cylindre extérieur est comprise entre 8 millimètres et 12 millimètres afin d'assurer une bonne transpiration tout en conservant une rigidité nécessaire à la résistance aux chocs qui pourraient intervenir lors du transport et du montage du dispositif et lui permettre également de supporter la pression de l'eau qui ay est contenue. The thickness of terracotta forming the outer cylinder is between 8 millimeters and 12 millimeters in order to ensure good perspiration while retaining the rigidity necessary for the resistance to shocks which could occur during transport and assembly of the device and allow it also withstand the pressure of the water contained therein.

Par ailleurs, la hauteur et le diamètre de l'enselllble seront calculés afin que la surface développée d'évaporation qui est en contact avec l'air extérieur soit de l'ordre de 2 mètres carrés (hauteur 1,60 mètre et diamètre 0,40 mètre par exemple) mais ces dimensions pourront être revues en fonction de l'importance de l'installation de ventiloconvecteurs à alimenter en liquide réfrigérant. In addition, the height and the diameter of the whole will be calculated so that the developed surface of evaporation which is in contact with the outside air is of the order of 2 square meters (height 1.60 meters and diameter 0, 40 meters for example) but these dimensions can be revised depending on the size of the installation of fan coils to be supplied with coolant.

Les autres composants du dispositif ainsi que son installation apparaîtront au cours de la description qui va suivre faite en référence aux dessins annexés qui en illustrent une forme de réalisation dans son principe à titre d'exemple non limitatif. The other components of the device as well as its installation will appear during the description which follows made with reference to the appended drawings which illustrate an embodiment in principle thereof by way of nonlimiting example.

Les dessins annexés illustrent l'invention:
-Le dessin i représente une vue éclatée du dispositif avant assemblage avec les deux tubes concentriques de même longueur et les deux couvercles. The accompanying drawings illustrate the invention:
The drawing i represents an exploded view of the device before assembly with the two concentric tubes of the same length and the two covers.

-Le dessin 2 représente le dispositif dans son principe, posé sur le sol, branché, relié à un ventilo-convecteur et prêt à fonctionner. -Drawing 2 represents the device in principle, placed on the ground, connected, connected to a fan coil and ready to operate.

En référence à ces dessins, le dispositif comporte (dessin 1) deux tubes de meme longueur en terre cuite (fig. 3), le couvercle bas (fig. 4) et haut (fig. 2). Les tubes sont soudés concentriquement à la barbotine et par cuisson aux couvercles par ajustement dans les gorges ; l'étanchéité du tube de moindre diamètre s'effectue par émaillage de sa paroi interne. With reference to these drawings, the device comprises (drawing 1) two tubes of the same length in terracotta (fig. 3), the bottom cover (fig. 4) and top (fig. 2). The tubes are welded concentrically to the slip and by baking to the covers by adjustment in the grooves; the tube of smaller diameter is sealed by enamelling its internal wall.

Cet assemblage constitue deux récipients solidaires mais indépendants Ri et R2. This assembly constitutes two integral but independent containers Ri and R2.

L'alimentation en eau destinée à l'évaporation du récipient Ri se fait par l'orifice A et la vidange, en période-froide, -par l'orifice V, afin d'éviter dans ce dernier cas tout incident de rupture qui pourrait être occasionné par le gel de l'eau qui y est contenue. The water supply intended for the evaporation of the container Ri is done through the orifice A and the emptying, in cold period, -by the orifice V, in order to avoid in the latter case any incident of rupture which could be caused by the freezing of the water contained therein.

La distribution du liquide réfrigérant contenu dans le récipient R2 dans l'installation de ventilo-convecteurs s'effectue par pompage par l'orifice P et son retour par l'orifice R. The coolant contained in container R2 is installed in the fan coil installation by pumping through port P and returning it through port R.

Le dispositif représenté, posé ici en extérieur sur un socle de béton et prêt à fonctionner (dessin 2) est relié à un tuyau d'alimentation d'eau TA, un tuyau de vidange pour l'hiver TV, un tuyau de retour de liquide réfrigérant TR et un tuyau de pompage vers le ventilo-convecteur; ce tuyau de pompage TP est terminé par une sonde rigide en matière synthétique ou métal inoxydable qui récupère le liquide réfrigérant dans la partie inférieure du récipient R2, les liquides froids étant plus lourds. The device shown, placed here outside on a concrete base and ready to operate (drawing 2) is connected to a water supply pipe TA, a drain pipe for winter TV, a liquid return pipe TR refrigerant and a pumping pipe to the fan coil; this TP pumping pipe is terminated by a rigid plastic or stainless steel probe which collects the coolant in the lower part of the container R2, the cold liquids being heavier.

Les tuyaux TP et TR sont enfin reliés à un ventiloconvecteur pour en assurer l'alimentation en liquide réfrigérant.  The TP and TR pipes are finally connected to a fan coil to ensure the supply of coolant.

En variante non illustrée, la section circulaire extérieure telle que représentée en figure i pourra adopter une autre forme géométrique telle que carrée, rectangulaire, demi-circulaire, ellipsoldale, cette liste d'exemples étant non limitative, ces formes s'adapteront en fonction de l'exposition au soleil ou au vent recherchée et afin de respecter certains autres impératifs d'ordre architecturaux ou esthétiques. In a variant not illustrated, the external circular section as represented in FIG. I could adopt another geometric shape such as square, rectangular, semi-circular, ellipsoldal, this list of examples being non-limiting, these shapes will adapt according to the sun or wind exposure sought and in order to meet certain other architectural or aesthetic requirements.

En deuxième variante non illustrée, le dispositif pourra-être fixé en hauteur, contre la façade d'un immeuble. In a second variant not shown, the device could be fixed in height, against the facade of a building.

Le dispositif selon l'invention est particulièrement destiné à alimenter en liquide froid un ou plusieurs ventilo-convecteurs.  The device according to the invention is particularly intended for supplying cold liquid to one or more fan coil units.
