Industrialized thermal enclosure of easy assembly. Field of the Invention

The present invention refers to a ceramic thermal enclosure whose purpose is to cool or heat a surface without energy input that has the ease of being able to be disassembled simply and comfortably.

The object of the invention is to associate an endothermic effect of the porous ceramic to enclosure panels and thus con fi ne a space whose interior is conditioned by this system. This con fi nmation can be applied both in mobile installations such as booths, caravans, toilets, pavilions and the like, as in fixed installations for example in buildings. Background of the invention

As is known, in the Mediterranean region, man has always used mud to make containers for food preservation, because the Mediterranean climate in summer is very dry in contrast to other regions, which usually have wet summers.

The history of the botijo goes back to the ancient Mesopotamian cultures, as remains of containers with similar shapes to the current ones are found. Although the evaporation cooling system is very old and it seemed that it had lost its usefulness in the face of modern refrigerators, in developing countries, of arid climate and without electricity, it has its justi fi ed importance.

Recently, the Rolex Foundation awarded one of its awards to Mohammed Bah Abba for building a double crock to conserve perishable food. The system consists of two vessels, of different diameter, including one inside the other. The space that mediates between the two is filled with sand, which must be constantly soaked to ensure humidi fi cation of its walls. Fruits, vegetables and other foods are placed in the inner vessel.

The physical explanation of the cooling process is simple: the water contained in the sand that separates both vessels evaporates towards the outside of the main vessel, ventilated by the circulation of the dry air outside. The evaporation process involves a reduction of several degrees in the temperature of the sand, which cools the inner vessel, retards the reproduction of decomposition agents and preserves food. Thanks to this simple method, the preservation of eggplants, for example, went from 3 to 27 days and that of tomatoes and peppers, to three or more weeks.

It should be said that since ancient times the buildings have been built with mud, the most famous case is the Djingareybe Mosque of Timbuktu, which every year the rainy season is rebuilt with more mud. The operation of this building or other similar buildings is related to the operation of our system, due to the porous characteristics of the mud, but the invention we provide presents a series of advantages compared to the known background.

The most similar system found has been a work of Loreto Moreno González, a student of Architecture Projects V of the ETSAM. In his dies precisely to fill that lack. Porous ceramic objects are also attached to that structure, and they are rhomboid pieces that also work by the "botijo effect". In fact they are like flattened jars attached by the structure one meter from the facade. At no time do they claim to be an enclosure, but it is a cooling sieve as an exterior lattice.

In comparison we can comment that the systems that are known must be moistened manually so that the water undergoes evaporation, since they lack an irrigation system. Another difference is that only with the mud the perspiration towards the interior is not assured, since there can be parts of the system with greater ventilation by the interior face, or even on rainy days in which when there is a drier interior environment, the humidity pass in. They also lack an external ventilation chamber. Nor is it an industrialized system, which has the ability to assemble and disassemble easily.

The fundamental differences in relation to the closest antecedent is that our invention allows heating and cooling, while the aforementioned antecedent only cools the air. In addition our invention allows to be mounted on any type of structure and offers thermal and acoustic insulation at the same time. Explanation of the invention.

The invention refers to a removable enclosure system capable of conditioning (cooling and heating) spaces without the need for energy input. The use of porous ceramic containers with sand or soil content, ventilation chamber and a water supply allows water to evaporate. When the water evaporates it needs energy for the change of state from liquid to gas. That energy can take it from the environment, but also from the system itself. So when a part of the water evaporates, it extracts energy from the system and then the remaining wet ceramic and substrate assembly decreases the temperature.

Using the kinetic theory we can explain the phenomenon of evaporative cooling from the microscopic or molecular point of view. Thus, we find that the particles of a solid, liquid

or gas is moving or stirring continuously. Temperature is a measure of the average kinetic energy of the particles, higher velocity of these implies higher temperature and vice versa. In a liquid, the particles move by sliding over each other, the fastest ones approach the free surface of the liquid and if they have enough energy they can escape from it, causing evaporation. This change of state causes a cooling of the system, since precisely the most energetic particles disappear.

Through this process, the piece that, in direct contact with the interior space, begins to cool the air closest to its surface, is cooled down, since it is now denser and precipitates, creating a downward convection current that, in turn, pushes the air from the room again to the closing by its upper part, closing the current and cooling the entire room. Additionally we have the cooling that is generated by radiation when approaching the enclosure.

3 EN 2352405A1 4

The operation of the system requires a water supply that can come from the power supply, general water treatment plant, treatment plant of the same building or mobile installation.

To make a brief general summary of the operation of the system we will explain it in layers from the innermost part of the cabin to the outside. Initially we have a water vapor impermeable layer that is the internal image of the enclosure, its function is precisely to prevent the flow of steam into the interior. Continuing towards the outside we find a layer of substrate that stores the water in the entire surface of the enclosure. The difference with respect to an empty layer as if it were a bottle, is that using that empty layer would reduce the evaporation surface thus reducing the cooling effect. The following is the porous ceramic evaporator layer that absorbs water from the previous substrate layer to evaporate it from its outer face in contact with the air in the atmosphere, it is the air chamber and it is the penultimate layer of the whole. This air chamber enhances the flow thanks to the con fi nmation provided by the last layer, which, like the first one, can be of any material.

In addition to the advantages already mentioned that involves an industrialized enclosure, easy to assemble, with all the layers in one and with a certain degree of detachability in case of pieces breaking, we can comment on numerous other advantages, among which we can mention as more remarkable the following:

•

Maximum use of space and a pleasant aesthetic appearance, since on the one hand the boiler room, chimneys, fuel tanks, etc. are suppressed, and on the other hand, the tendency in modern architecture is to create clear, clear environments , cozy and without compromising accessibility, with large floor-to-ceiling windows, so that for this type of construction the ceramic thermal enclosure system is ideal, gaining greater freedom for decoration, since the premises are completely free of appliances (air conditioners, radiators, heaters) that condition aesthetics and space.

•

Minimum system thickness of 7.5 cm compared to 20 or 25 cm of a conventional multilayer enclosure.

•

It can be mounted on any type of structure: steel, reinforced concrete, wood, polymers, etc.

•

Mixed system that uses negative radiation (takes energy from the bodies) by transpiration of water and thermal accumulation for its operation. Due to the high thermal capacity of both materials, heat or cold accumulates throughout the volume of the enclosure to dissipate it as soon as the sun is over.

•

Air conditioning capacity that allows adapting to other current or future variables, such as type of clothing, physical activity, etc. of the people existing in the stay.

•

It offers thermal insulation (when the substrate is dry) and acoustic insulation by

Ceramic density and mass-spring-mass absorption system (ceramic-substrate-ceramic or other waterproof element).

•

A moderate and controlled temperature is achieved in the room where the system is installed, thanks to the fact that there are no heating elements at high temperatures. Uniform air conditioning is then obtained without feeling neither cold nor excessive heat due to the limitation of cooling down to the dry air temperature in case of summer or simply opening the windows in case of excessive solar radiation in winter.

•

A healthy heat or cold is achieved since there is no sudden movement of the air that raises the particles of burnt dust, since it does not consist of heating elements at high temperature, so that the dust particles cannot get burned, avoiding the irradiation of the airways that burnt dust produces.

•

The relative humidity of the air influences less when the air is not heated, but the materials and objects of the room. The natural humidity of the environment is not lost and the annoying winter respiratory problems caused by conventional heating are minimized. The same happens in summer with the dryness produced by air conditioners.

•

Economic savings by air conditioning, either electric or gas. The only consumption made by the system is water that can take advantage of a rainwater collection tank

or even purified gray waters while they have no residual mineral residue or salt that can precipitate in the chamber of the ceramic substrate or container. This contributes to sustainability because it avoids the consumption of energy that may come from the combustion of fossil materials.

•

It can be installed as an external material of the ventilation chamber, a solar panel system, further reinforcing its ecological character.

The system reduces the outside temperature, so that on certain occasions it can be beneficial both internally and externally. The degree of recyclability can reach 100% depending on the type of combination that has been chosen. Detailed Explanation

The enclosure works with a water supply that can be received from the power supply, general water treatment plant, treatment plant of the same building or even the purified gray water while it has no suspended residue. The water is distributed from the top of the ceramic containers, by means of an irrigation tube with drippers 11 coupled in the upper hole 26. In this way, from the first row the water is fi ltered to the lower rows so that it feeds the rest of the pieces that make up the enclosure. To safeguard the gaps, special pieces with holes have been used to pass tubes 22 vertically downwards until reaching the solicitation zone. This added to connectors in the form of "T", makes the vertical water fl ow drift horizontally to another irrigation tube with drippers 11. This

5 EN 2352405A1 6

The system has a fi lter filter to inject clean water into the ducts and substrate chambers 2.

The attachment of the pieces to the structure of the space to be con fi rmed can be resolved in several ways. For example, by interposing a multiple substructure 25 to which we anchor the pieces; or by adhering that substructure to the pieces as a reinforcement of the ceramic container 20; also directly supporting the pieces to the structure 14 by means of anchors of any type 7 and 8, as long as they do not damage the ceramic container 3 the ventilation chamber 4.

The dimensions, shape, color and texture of the ceramic piece may vary depending on the use to which it is intended. In this way, enclosures can be formed that are not only flat and straight, but also have curved, sinusoidal and even three-dimensional shapes. The same applies to the ventilation chamber 4 and the inner material 1, which can vary in thickness and shape according to the requirement of the outer material 5 of the chamber.

The ventilation chamber 4 allows an upward or downward flow of air, either from the lower or upper part of the piece, through the complete enclosure or through areas (from lintel to windowsill, or from hollow to hollow).

The outer material 5 that forms the ventilation chamber can be of any type, even the outer material 5 can be formed with the same porous ceramic of the ceramic container 3, all in one piece or two duly adhered. The only condition is to allow a fluid flow without obstacles that decreases the air velocity.

Optionally, this camera can be connected to a Shuntt type forced draft element or a mechanical air extraction system. Although the second option limits the main idea of not providing energy, since it makes essential in the case of a built-in context, minimal natural ventilation or sunlight.

The outer material 5 of the ventilation chamber 4 can be at the same time the multiple substructure 25 that is anchored to the structure.

In some areas it has been convenient to use an element with luminescent properties that connects the exterior with the interior, so that during the day it captures light energy and during the night it releases it radiating both inside and outside. This element can be at the same time the material that defines the ventilation chamber 4 and the multiple substructure 25 or simple substructure 21.

For the operation of the system in the cold season, the evaporation surface (outer face) of the ceramic container 3, a dark colored element 18, must be placed in contact with the ventilation chamber 4 to prevent steam from escaping. water, keeping it inside the container. This element can be of any shape, size and texture as long as it prevents water from leaving the system. The placement of this element must be done in the summer-winter cycle change and removed in the winter-summer cycle. In order to raise the level of interior comfort, some improvement of the system was considered, automating the dark colored element 18 so that the element was automatically disposed according to the internal thermal requirements. An even higher level of comfort can be reached if an intelligent fabric or membrane can be interposed between the layers 2 and 3 capable of modifying its structure to regulate the passage of water. This regulation can be given directly according to the outside temperature or by controlling it with electrical signals from a control unit or computer in the system.

The ceramic piece can be constituted as a single-height enclosure with an entry hole through the top cover 10, but a multi-storey enclosure can also be constituted, in which case it must have a top hole 26 in the top cover 10 and another lower hole 29 in the lower cover 16, so that the water flows in the different pieces.

The design of the ceramic pieces includes gaps for the passage of installations, both horizontally and vertically, either through visible or hidden channels with specific pieces that make up the changes of direction or connection sockets.

For a combined structure of several pieces, the vertical joints between ceramic pieces have been resolved without touching, glued or tongue and groove. If they are tongue and groove, they have an accommodation material 19 with elastic and insulating properties. It also happens with the horizontal joint in the substrate chamber 2.

As for the horizontal joints, if it is a single-height enclosure or that the ceramic containers 3 overcome an obstacle such as a floor slab, the lower hole 29 must be connected to the upper hole 26 by means of a tube. In case of direct contact or sticking, it is finished off with an element (elastomeric material such as rubber

or EPDM) which acts as a sealing gasket between the lower cover 16 and the upper cover 10, to prevent water loss. The tongue and groove would be chosen in case a clipping system is designed that joins the lower lid 16 and the upper lid 10 by pressure and, having elements that safeguard the water fl ow to avoid losses (similar to the previous case).

It is important that in the glued or tongue and groove joints of the lower cover 16 to the upper cover 10, a fi lter that avoids the obstruction of the water fl ow between chambers is interposed. If it is the last lower part, it must have a plug-like element 17 that prevents water from flowing out.

The inner face 28 of the inner material 1 together with the lateral faces 30 and areas through which the air of the ventilation chamber 4 does not flow must be impervious to water vapor. This prevents internal or residual humidification between ceramic pieces, which causes condensation, mold, oxidation of the substructure, etc.

To achieve this waterproof inner face 28 we employ several strategies, the first and most common in the world of ceramics is to glaze it with silica, the second was to waterproof with polymeric paints or resins, and the third, to make multiple substructure 25 wrap that face internal 28.

The closing of the horizontal zones that the system does not reach is terminated with a thermal insulation 27, in order to avoid the loss of air conditioning obtained by the ceramic pieces. Brief description of the drawings
