Description

Roof, of ordinary appearance, comprising a device for thermal recovery of solar radiation invisible from the outside

A series of roof modules absorb solar radiation and release the stored heat to a specific heat transfer network of new design, positioned on a dedicated support fixed to the frame.

The device is intended for heating and producing hot water for homes by using environmental heat absorbed by the roof modules and also for heating swimming pool water.

This heat transmitted by the heat transfer fluid supplies market development devices such as so-called “water/water” heat pumps, direct solar floors, or exchangers.

This heat can also recharge geothermal catchments during the hot season.

State of the art

There are different systems for thermal recovery of solar radiation usually made up of independent solar panels mounted as an imposition or incorporated on the roof.

These solar panels have various drawbacks known to professionals and illustrated by specialized literature. The best known are the heavier structure, difficulties in waterproofing the rest of the roof, and the use of additional materials which make construction more expensive. Also, the use of metal products for the structure which requires extraction energy and a carbon-emitting logistics chain. Another disadvantage is an aesthetic contested by local residents.
In certain cases, these visible sensors are prohibited in the context of heritage protection by areas protected as historical monuments or urban and landscape heritage protection zones.

More discreet recovery systems have been designed to meet the aesthetic needs of these buildings as well as the various disadvantages encountered by the installation of sensors.

Some of these proposals take up the principle of installing panels whose surface facing is made with classic roofing materials and hide sensors of classic design. They solve the problem of aesthetics, but have a sensor on the underside comparable to those used for traditional sensors, which makes the roof heavier and makes their supply more expensive.

The state of the art shows that there are other solutions compatible with these technical considerations and in particular my patents 08 04 659 FR, 10 04 074 FR, 12 01 440 FR.

• Pour le premier brevet FR 2935 172 par la qualité aléatoire du contact entre le réseau et les modules de toiture ne permettait pas une bonne transmission de la chaleur.
• Le brevet d’amélioration FR 2966 228 qui concerne un support spécifique apporte une amélioration trop coûteuse et fragile pour la réalisation d’un système d’ancrage des modules.
• Le brevet FR 2990 970, apporte une réponse nouvelle et satisfaisante pour résoudre les difficultés précédentes par l’utilisation d’un réseau qui comporte une gorge dans laquelle s’insère un bourrelet situé sous le module de récupération thermique. Le contact entre les modules et le réseau caloporteur est d’excellente qualité, mais cette technique présente d’autres inconvénients.

These systems have disadvantages:

• For the first patent FR 2935 172, the random quality of the contact between the network and the roof modules did not allow good heat transmission.
• The improvement patent FR 2966 228 which concerns a specific support provides an improvement that is too costly and fragile for the production of a module anchoring system.
• Patent FR 2990 970 provides a new and satisfactory response to resolve the previous difficulties by using a network which includes a groove into which a bead located under the thermal recovery module is inserted. The contact between the modules and the heat transfer network is of excellent quality, but this technique has other disadvantages.

The first concerns the radius of curvature with this specific network greater than that expected to move from one row of modules to the next without bending it. Indeed, after each row of modules, the network forms a lateral curve of reduced radius to join the row of tiles located above or below, which bends the network and obstructs the passage of the heat transfer fluid.

These breaks in the circulation of the heat transfer fluid are an obstacle which was resolved and presented to the public by the use of specific junction connections between the heat transfer network located under the tiles and the circular lateral curves allowing the network to be turned around.

But the consequence is to split the network into numerous parts, with too many connections, which unfortunately creates a significant risk of leakage from the network under the roof and eliminates one of the hoped-for reliability advantages.

In fact, an ordinary roof has dozens of connections constituting as many risks...

A technique of overmolding the fittings on the network is possible and reliable, but requires expensive tools; and delicate implementation by prefabricating the network lines under the roof in the factory.

Network bundles mounted with terminal connections cannot be transported in rings and require flat transport in a semi-trailer, which makes transport, handling, and storage costly and difficult, and which also limits the width. roof sections treated in one length.

The risk of leakage persists by mounting one side of the fittings towards the circular side loops and then towards the collectors, in fact, mounting the fittings on the roof creates too many risks of poor sealing.

Another disadvantage is that when there is excess internal pressure, the specific network brings out the groove and pushes the tiles out of the support, creating a mess on the roof.

Technical solution

Another approach makes it possible to respond to these difficulties and finally makes it possible to achieve the thermal capture of solar radiation, invisible, economical and efficient. The roof according to the invention allows the thermal capture of solar radiation to be achieved by overcoming these drawbacks.

It consists of creating an ordinary-looking roof by setting up thermal recovery of solar and environmental heat invisible from the outside. This invention makes it possible to resolve the difficulties encountered with previous techniques.

It makes it possible to maintain the advantage of very good contact between the heat transfer network and the roof modules and to eliminate too many connections located at the end of the recovery lines and susceptible to leaks.

It helps avoid problems on the roof such as the expulsion of roof modules from the support during excessive or accidental increases in pressure in the network.

It offers the advantage of using circular connectors on the market, inexpensive and reliable, for the terminal connection of the networks to the feeders, similar to what is done with reticulated polyethylene heated floors.

In the event of an increase in pressure in the heat transfer network, it does not expel the modules, but contributes to improving contact by lateral compression of the thermal transmission interface. Between the network and the modules.

detailed description

Thus the roof according to the invention comprises at least one module for thermal recovery of solar radiation.

Roof modules which receive and transmit solar radiation and include at least one protruding bead intended to be placed laterally in contact with one or two heat transfer networks.

Roof modules whose function is to transmit heat to the heat transfer network can be made from many materials.

As non-limiting examples, these roof modules can be made of terracotta, zinc, copper, stainless steel, etc.

In this document the word: “module” refers to “roof modules” intended for the thermal transmission of heat collected on the roof to the heat transfer network.

In the case where the modules are made of terracotta, the word tile will be used interchangeably, as it is perceived from the outside, and because of its covering function.

In the case of metal sheets which perform the thermal recovery and covering functions, the words will be used interchangeably: “sheet”, “roofing sheet” or “module”.

The roof modules are characterized by at least one protruding projection or bead located on the underside, oriented downwards and invisible from the outside.

In this presentation, the expression “protruding protrusion”, “protruding part” and “bead” represent the same part of the roof module intended to be inserted into the groove to then come into contact with the heat transfer network(s).

Thermal recovery modules comprising at least one protrusion or bead on the underside.

These thermal modules can have several protrusions or ridges on the underside.

In certain specific cases of construction, the bead performs the function of fixing the roof module to the frame.

As a non-limiting example, a tile will be fixed at the top by this bead which replaces the usual molded lug located at the end.

The protruding bead which is positioned in contact with the network also makes it possible to secure all the roof modules to the frame.

The installation of the modules provides a fixing of less resistance than that of a traditional fixing such as with a nail, but contributes to the cohesion of the covering elements in the event of storms or earthquakes.

The modules in contact with the networks are characterized by the friction of their beads, against the heat transfer networks which are trapped in their cradles.

Friction varies depending on the characteristics of the materials making up the networks and modules, and also by their sections and, where applicable, by the filling pressure.

This resistance by the beads of the roof modules will require a resistance experiment in a wind tunnel to characterize the effect and the limits.

The environmental heat heats the entire thermal recovery module and transmits the heat by conduction to the bead located on the underside.

This module, when it is made of terracotta, takes the form of an ordinary-looking tile whose modified underside includes the protruding bead(s) intended to be inserted into contact with the heat transfer network(s).

In the case of metal construction, the modules can be made by shaping metal sheets.

In the case of metal, this module will then be: either a specific transmission part which is located below the usual sheets of the cover and will serve as a mediator in thermal conduction; either a sheet of metal from the cover which has the protruding bead(s) intended to be inserted into the supports.

According to a particular mode of the invention, the beads of the modules allow them to fit together for the same support.

In this particular embodiment of the invention, two roof modules successively join the groove located at the same location in the support.

In this case, the first roof module is also characterized by the rear part of the beads which has a hollow allowing a second bead to be inserted from behind.

As a non-limiting example, the roof module is directly the metal sheet which provides the visible facing instead of the sheets usually used.

In this common case and as a non-limiting example, the fineness of the metal sheet is less than a millimeter (sheets on the market often range between 6/10th and 8/10th of a millimeter) and facilitates hollow shaping of the bead.

The first module is characterized by its bead which includes a hollow located inside this protruding profile intended to receive the bead of the second module from the rear.

Thus, in this particular case of embodiment of the invention, the first roof module which has a recessed rear location is positioned identically to the other roof modules in the support in contact with the heat transfer network(s).

The second module is characterized by the dimensions of the bead adapted to fit into the first module.

The second module is characterized by its protruding male profile or bead intended to be inserted into the hollow located at the rear of the bead of the first module.

Thus this variant of the innovation is characterized by the support allowing two roof modules to be fitted one on top of the other while retaining their basic characteristics.

The contact transmission of the external thermal input from the second module to the network is carried out by conduction via the bead of the first module.

The two modules are characterized by their nesting intended for the same support and the same network(s), they jointly supply the heat supply by conduction to the heat transfer network.

A metal roof module serving as a mediator can also be covered with slates installed with nails in the same way as slate roofing on battens. Care will be taken to protect the network from nailing of the slates by prior identification. The rebate of the metal module will eventually be perforated.

The roof according to the invention also includes at least one heat transfer network.

• Le réseau caloporteur est flexible, ce qui lui permet de suivre le tracé fixé sur la toiture.
• Le réseau est élastique pour permettre des modifications de section sans détérioration ni rupture de son enveloppe.

The newly designed heat transfer network is made of any material which has flexibility and elasticity characteristics allowing its geometry to be modified by mechanical constraints external or internal to its envelope.

• The heat transfer network is flexible, which allows it to follow the route fixed on the roof.
• The network is elastic to allow section modifications without deterioration or rupture of its envelope.

In this presentation, the word “network” always designates the expression “heat transfer network” and the two methods of designation are used interchangeably.

As a non-limiting example, a network made of thermoplastic material composed of a mixture of ethylene-propylene-diene monomer and polypropylene can meet these technical requirements.

According to a particular non-limiting embodiment, the network can be produced by extrusion according to the parameters described to meet the advantageous characteristics in particular: the connection after deformation of the section by circular sealing devices to market standards, the use sheaths from the market, monitoring the layout on the roof…

The heat transfer network is characterized by its flexibility which allows routing in a limited space under the roof without obstructing the passage of the fluid.

Thus, said heat transfer network is characterized by its elasticity which makes it possible to modify the shape of its section by mechanical stress.

Said network is also characterized by its flexibility which allows it to follow the route established on the roof.

The heat transfer network is characterized by its envelope which allows, through contact, the thermal transmission of the roof module heated by external contributions from the environment to the fluid circulating in the heat transfer network.

• au moins une partie de section elliptique.
• une zone destinée au contact vers les bourrelets des modules de toiture.

On the other hand, the heat transfer network includes:

• at least one part of elliptical section.
• a zone intended for contact with the beads of the roof modules.

The network can be of entirely elliptical section, in this case the contact zone intended for heat exchange towards the roof beads is produced after elastic deformation caused by the assembly of the modules.

Or present a mixed section composed of an elliptical part intended to be inserted into the cradle of the roof support and a surface adapted and optimized for contact with the male bead of the roof module.

The heat transfer network is characterized by the part of elliptical section which conforms to the shape of the cradle and blocks its rotation in the support when the protruding bead located under the roof module is introduced.

The heat transfer network held laterally by the cradle allows, by the filling pressure and/or by the elastic reaction, to make lateral contact along the beads of the roof modules, without this force being able to allow an upward ejection movement of the roof module. roofing.

The positioning of the network in the cradle when the roof module is inserted into the support prohibits any movement of the network towards the top or bottom of the support.

In fact, the network is trapped in the cradle and by lateral support on the bead of the modules.

The lateral contact friction with the beads keeps the roof modules in position.

Thus, the heat transfer network is characterized in that it comprises a section of which at least part is elliptical and its elasticity which allows it to pass through the groove to the cradle and to conform laterally to the shape of the protruding bead parallel to the axis on its long side.

The elliptical section part of the network determines a corresponding geometric ellipse.

This geometric ellipse corresponds to a network which would be entirely elliptical in continuity with the existing elliptical part, it determines the eccentricity characteristics of the foci and the position of the major axis and the minor axis as a positioning reference.

Thus, this part of the elliptical section of the network is characterized by the foci of the geometric ellipse.

The elliptical part of the network is positioned in the cradle of the roof support and can extend on either side in the continuity of the geometric ellipse.

The heat transfer network has a surface intended for contact with the roof modules which is either elliptical or adapted to the profile of the bead of the roof modules.

According to certain particular embodiments, this surface can be flattened to facilitate assembly by inserting the male bead of the roof modules, and then to allow good contact between the network and the beads of the roof modules.

The part of the network which is not elliptical can thus correspond precisely to the geometry of the bead of the modules for better contact.

This geometry of the heat transfer network is represented in this non-limiting example, , thus the elliptical heat transfer network has a flattened contact surface to promote thermal transmission with the roof modules.

In this example, a flat contact panel allows the network and the protruding profiles of the modules to coincide.

Thus the network is introduced through the groove to be positioned and mounted in the cradle.

The cradle of the support maintains the focal axis of the geometric ellipse corresponding to the part of elliptical section of the heat transfer network, which fixes its position waiting for the network and subsequently limits the inclination with respect to the protruding axis of the bead of the modules within the limits of the acute angle.

The angle of incidence at the time of assembly, constituted by the tangent at the contact point of the network, and that of the bead, is sufficiently acute to allow the bead to slide along the network and if necessary the deformation of said network without movement or crushing.

In fact, the network is held in position by the cradle of the support waiting for the roof modules.

At the time of assembly, the network allows the sliding of the protruding bead parallel to its focal axis for the installation of the thermal recovery module.

In a particular case of realization, the elastic deformation of the network created by the assembly of the roof module by depression accompanies the sliding of the protruding bead during the assembly operation.

Then once completely inserted, the elastic potential energy stored during compression by the assembly leads the network to return to its initial shape and presents a thermal transmission surface by conduction between the network and the modules.

The network is characterized by its elasticity which allows longitudinal contact on the protruding part of the bead of the thermal recovery modules.

Indeed, the bead has a projecting part intended to be positioned laterally in contact with the outside of the heat transfer network, when the heat transfer network is connected in a closed circuit the pressure of the network pushes the envelope of the network against the protruding bead.

• Soit d’améliorer le contact existant entre le réseau caloporteur et le bourrelet saillant.
• Soit de permettre ce contact par la déformation du réseau en l’absence de contact initial.

This internal pressure of the network results in:

• Or to improve the existing contact between the heat transfer network and the protruding bead.
• Or to allow this contact by the deformation of the network in the absence of initial contact.

The deformation of the network by pressure and elastic potential energy allows nesting with the protruding bead of the thermal recovery modules, and this part in contact perfectly matches the irregularities of the contours by a slight deformation, for better efficiency of heat transfer .

• Épouser latéralement le bourrelet saillant du module pour un bon contact de transmission thermique
• Revêtir une section circulaire pour réaliser le raccordement et permettre de boucles sans pliures

The elasticity of the network allows, under stress, the deformation of its section to obtain two characteristics:

• Follow the protruding bead of the module laterally for good thermal transmission contact
• Cover a circular section to make the connection and allow loops without folds

Said network is characterized by this elasticity which makes it possible to conform laterally to the shape of the protruding bead.

The elasticity of the network allows, through the filling pressure of the network, to maintain lateral thermal transmission contact along the beads of the roof modules.

Said network characterized by its elasticity which makes it possible to obtain a circular section by a mechanical stress applied to its envelope and to meet the objective of a simplified connection with market fittings and the creation of lateral loops without crushing.

The elastic qualities of the network make it possible to produce a circular section by a mechanical stress distributed over this area of the network envelope.

The heat transfer network is characterized by its elasticity which allows, in the absence of constraint, to return to the original section of the network by elastic reaction.

The elastic reaction of the network avoids the risk of accidental deformation during installation, for example by trampling on it.

According to a particular embodiment, it contributes to good contact with the bead of the module in the absence of sufficient internal pressure.

Indeed, according to this particular embodiment, the elasticity of the heat transfer network allows, in the absence of sufficient pressure inside the network following filling, to maintain lateral contact by elastic reaction along the beads of the modules of roof to allow heat transfer from the roof module to the heat transfer fluid.

This characteristic makes it possible to operate with an open heat transfer network, the internal pressure of which is zero in certain places, with, as a non-limiting example, the heating of swimming pool water in an open circuit.

The elasticity of the heat transfer network makes it possible to pass through the groove to the cradle and to conform laterally to the shape of the protruding bead parallel to the geometric axis of the long side of the part of elliptical section.

In the case of a support which has an opening located in the upper part of the groove that is too narrow for the passage of the network, a mechanical constraint makes it possible to reduce the dimension of the small geometric axis of the section of the network for its passage towards the cradle of the support.

The elasticity of the network allows, through a constraint, to modify its section in order to fit into the cradle, but also to obtain a circular section.

This elasticity makes it possible to modify the shape of the network without creating a break to allow a circular connection with standard products on the market,

As a non-limiting example of an embodiment, a metal insert placed inside the network envelope makes it possible to form the circular section for the standard connection.

At the location of the reversal loops, the constraint by a sheath makes it possible to maintain a section free of circulation and a satisfactory passage inside the network.

Once the section has been modified, it is possible to force the heat transfer network to maintain the circular section by inserting a ring, a circular sleeve, an insert, by sliding it into a sheath, also by rigid waterproof junction connectors such as connectors. crimping the market for flexible network applications, but also by the pressure of the fluid when the network is closed.

When the network is outside the support, as happens on the periphery of the roof near the edges, a mechanical constraint exerted by a sheath on the envelope of the heat transfer network makes it possible to maintain a passage for the fluid.

The elasticity of the network allows the exterior of the supports, under the constraint of an external sheath or by internal pressure to maintain the passage for the heat transfer fluid.

Thus, the constraint of the sheath on the network prevents it from being crushed and blocking the fluid circulating inside the curves.

To do this, it is necessary to have a circular sheath with a perimeter close to that of the heat transfer network to constrain it.

The sheath can be corrugated like the sheaths for the passage of electrical cables, ensuring that the material is compatible with the temperature resistance. This type of corrugated sheath is particularly advantageous for constraining the network while facilitating the production of curves.

The sheath can also be insulating and thus prevent condensation on the outside of the support.

There are sleeves on the market that are split on the side with an adhesive to seal them under the name of insulation sleeve which are perfectly suited to this use.

Thus, the sheath protects the heat transfer network against bends at the level of the lateral turning curves on the roof located from one bank to the other or between the ridge and the sewer and it can have other advantageous characteristics such as insulating and/or functions. or additional protection against trampling before the installation of covering elements, but also to follow a path.

The partially elliptical network with a side adapted to the contact if it allows good contact presents a disadvantage for assembly on the construction site which is linked to its asymmetry in relation to the major axis determined by the corresponding geometric ellipse.

As a result of this asymmetry, the support which receives the network must present the cradle on the correct side at the risk of positioning the contact zone provided for the beads towards the hollow of the cradle.

This good orientation of the cradle requires prior preparation for the correct orientation of the supports before their attachments to the frame, which is not always acquired during execution on construction sites.

A solution in the event of poor positioning of the support would be to twist the network one hundred and eighty degrees when changing rows, but at the risk of creating tensions, instability, bends, and disorder during assembly.

This risk of incorrect positioning of the supports can be resolved in another way by using a fully elliptical network which offers reversible positioning.

A characteristic of the fully elliptical network is to allow a reversal of the lateral loops of the network towards the support, whatever the initial position of the cradle in the support.

Thus, in a particular embodiment of the invention, the section of the heat transfer network can be entirely elliptical.

The heat transfer network which has a completely elliptical section geometry allows lateral thermal transmission contact along the protruding bead of the roof modules by elastic lateral deformation.

The zone intended for contact with the beads of the roof modules is characterized by a network of elliptical section whose shape is modified by the insertion of the roof module.

According to an advantageous embodiment, the elliptical section of the network has sufficiently distinct geometric foci at rest to provide the bead with a better contact surface. This is more important with a less flexible network.

The elliptical heat transfer network is characterized by its ability to position itself in the support intended for the cradle, whatever its position in the support.

Indeed, the network by its symmetry does not impose a direction of installation as for the partially elliptical network.

The partially elliptical network is not symmetrical and must have its elliptical part on the cradle side and the other face, adapted to contact the bead, on the module side, which is not the case for a fully elliptical network.

Thus the elliptical network, with its axial symmetry, facilitates installation by avoiding any error in the direction of installation of the supports.

The elliptical section becomes circular under mechanical stress perpendicular to the axis of the short side.

The elliptical network is characterized by its ease of taking on a circular shape by simple compression applied to the two sharpest ends of the ellipse.

This constraint makes it possible to modify the elliptical section whose geometric foci are eccentric to obtain a circular section.

This characteristic is easily exploited with an elastic network.

The elasticity of the network makes it possible to obtain the circular section by a reversible adjustment by applying more or less strongly a mechanical stress in opposition to the elastic reaction of the network

Indeed, the elasticity of the network makes it possible to adjust the stress more or less strongly in opposition to the elastic reaction to reach the circular section.

In this case, the mechanical stress is exerted perpendicularly to the axis of the short side of the elliptical section, to lead to the geometric coincidence of the two foci, transforming the network from an ellipse section adapted to lateral contact, towards the particular ellipse of circular section favorable to standard connection, to the reversal of the network on the roof and to the creation of curves.

In this particular mode of the invention and according to a particular embodiment, an elliptical network, adapted to lateral contact has an eccentricity of the foci sufficient for the lateral surface of the network to initially allow a non-incisive passage of the bead of the modules and in a second step marries said heat transfer network by an elastic deformation in order to obtain an optimal contact surface between bead and network.

Starting from any elliptical section, it is simple to make it circular by compressing the network and without introducing additional constraints.

As non-limiting examples, this deformation under mechanical stress can be carried out from the outside by hand or, if the network is stiffer with the use of a tool such as a siphon pliers, by inserting a outer sleeve, by its forced insertion into a circular insulating sheath or not…

By way of non-limiting examples, the geometry of the elliptical network can also be modified from the inside with the use of a rigid metal insert, by the insertion of a conical sleeve, by a sleeve pliers, by the filling pressure of the heat transfer network…

A sheath can also maintain the circular section of the heat transfer network by an external constraint.

The networks intended to collect heat are positioned in cradles located between the side wall of the support and the bead located under the tile.

This lateral contact of thermal conduction is located in the direction of the long axis of the ellipse also called focal axis.

The geometry of this elliptical section network has two foci sufficiently eccentric to allow the passage of the roof modules in the direction of the focal axis.

The heat transfer network is characterized by its elliptical section homeomorphic to the desired circular section.

Modification by the operator of the shape of the elliptical network towards a circular section is possible by manual mechanical deformation.

The network is introduced through the opening located in the upper part of the groove.

According to a particular case of realization, the geometry of this network of elliptical section has two foci sufficiently eccentric to allow the passage of the heat transfer network through the groove of the support

If necessary, modification by the operator of the shape of the network makes it narrower for its passage through the throat.

The network is positioned in the waiting cradle and is protected from crushing by the roofers even before the roof modules are installed.

According to a particular embodiment, the networks are closed, the loops of the heat transfer network can join a feeder which collects all the loops located on the roof. This type of closed connection is possible even with a single loop and without feeders for thermal recovery devices.

These feeders collect the departures and returns to a conventional network with a larger diameter intended for devices which use and recover the transmitted heat.

This closed network to supply thermal use devices is filled with heat transfer fluid under pressure, generally with an antifreeze additive.

It is appropriate to adjust and dose this pressure applied to the heat transfer network to allow the deformation of the elliptical networks without risking reaching a mechanical breaking point of the network envelope.

The elliptical network located inside the battens will match the internal shapes of the constrained space between the bead and the cradle and apply a contact pressure towards the module which promotes heat exchange.

An advantageous characteristic is to apply, through the filling pressure, a contact pressure towards the protruding bead of the roof module, which has the effect of promoting good thermal transmission contact and compensating, if necessary, for the loss of elastic reaction that the network may encounter over time.

The heat transfer network characterized by its elasticity allows, under pressure of the heat transfer fluid, to exert a tightening and fixing constraint on the bead located under the roof module and to secure all of its elements against falling under the effect of the wind and light seismic movements in addition to the usual fixings.

At the lateral exit of the battens on the roof, the constraint which maintains the network in the shape inscribed by the niche formed between the cradle and the protruding bead no longer exists and the network under pressure naturally pushes it towards a circular shape.

On the other hand, the elliptical shape of the heat transfer network allows production tolerances and variations in shape within the limits of production and compliance with the characteristics described.

The shape of the network can vary from an ellipse to an ovoid or oblong section and retain the advantageous characteristics of the invention.

In this case the shape of the cradle is adapted to receive the heat transfer network

The roof according to the invention also includes at least one specific support.

Specific supports accommodate all modules and networks.

The support includes a groove which allows the passage of heat transfer networks and two lateral edges in mutual opposition, at least one of which includes a cradle which allows the heat transfer network to be accommodated within it.

These supports are fixed to the frame in the traditional way, for example with nails, screws, rivets, bolts and nuts, etc.

The positioning of the fixing towards the frame is free on all the supports, provided that the location intended to receive the network and the modules is left available.

These supports are characterized by their recessed profiles which include a base, two side walls, a groove, and at least one cradle.

The support is characterized in the case where it has only one cradle, by a sliding section located opposite the location of the recovery beads.

This sliding panel is intended to guide the bead when the roofing module is pushed in by the roofer and once inserted, to hold the roofing module in position.

This sliding section is characterized by its shape which takes up the protruding profile of the bead of the roof modules.

This sliding section is also characterized by its position on the opposite edge of that which contains the cradle housing the heat transfer network.

The support is also characterized by the bottom of the groove which has a bowl which can accommodate a fixing to the frame and, or collect the condensates.

The support by holding the cradle rigidly directs the deformation of the network laterally towards the protruding bead of the module.

The support is characterized by its mechanical resistance to elastic tensions and pressure exerted by the network when the filling is put under pressure and in contact with the roof module.

The support blocks the expansion movement of the network and directs the resulting force applied to the contact laterally towards the protruding bead of the module.

Pressurizing the network makes it possible to maintain good thermal transmission contact over time without the risk of ejection of the roof modules.

The roofer then positions the roof module by pressing the protruding bead into the opening formed by the groove of the support.

The roofer pushes the roof module, its protruding bead is positioned along the heat transfer network without damaging it.

It should be noted that the number of protruding beads under a module is not limited, so, as a non-limiting example, tiles with a fixing bead at the top are compatible with a second bead located just below the visible face.

In this case, the roofer then positions the roof module by simultaneously pressing the protruding beads into the openings formed by the grooves of the supports.

Said support includes at least one groove which allows the introduction of the networks towards the cradles.

A support can include one or two cradles which explains the plural used, and in this case the two networks are introduced successively to their respective cradles.

Thus, the groove is wide enough to slide the network into it beforehand for the cradles.

The groove guides the protruding beads of the module into contact with the networks.

The newly designed support laterally keeps the heat transfer network(s) in contact with the modules.

According to an advantageous variant, the support comprises two cradles, in this case the networks are positioned on either side of the protruding bead of the roof modules.

A support with two cradles makes it possible to position the two networks on either side in opposition and to double the surface in lateral contact on each roof module.

In this variant of the invention, the sliding section is replaced by a second cradle which also accommodates a heat transfer network, which makes it possible to double the exchange surface towards the bead, said heat transfer network is positioned symmetrically in opposition and replaces the sliding panel.

The sliding section can be replaced by a second cradle which doubles the exchange surface with the roof module.

The cradle and network couple takes on the characteristics of the sliding panel, and fulfills the same functions of mechanically maintaining the protruding bead of the modules.

The use of two networks per support improves roof heat absorption.

The support according to this variant of the invention is characterized by its two cradles which make it possible to accommodate two heat transfer networks on either side of the bead of the roof modules.

In this variant of the invention, the groove of the support guides the bead of the roof modules between the two heat transfer networks positioned in their respective cradles.

In this case, two cradles frame the protruding bead which is pinched between two networks in mutual opposition.

Thermal recovery through the use of two networks per support increases the contact surface and improves heat absorption on the roof.

The base is the part in contact with the frame or the panel which is extended by two side walls which frame the cradles and the groove.

Thus, said support is intended for fixing the network and the modules on the frame, comprises a base extended by lateral edges located in mutual opposition

The base can be pierced with one or more ventilation holes intended to meet the air renewal requirements on the underside of the roof.

For ventilation, the base can also be placed on a spacer which allows the passage of air under the support.

The walls in the extension of the base are positioned in mutual opposition allowing the maintenance of the heat transfer network(s) in contact with the bead of the modules.

The walls of the support contain either a cradle or a sliding panel.

The walls of the support are characterized by their rigidity which securely holds the modules and the network.

Said support is characterized by the presence of either a cradle facing a sliding section, or two cradles.

The sliding panel is located in front of the cradle to come into contact with the thermal recovery bead of the roof module and to hold it in position.

It is characterized by its shape which takes up that of the protruding bead and makes it possible to counteract the movement of the module subjected to the pressure of the heat transfer network.

The groove is an opening located in the upper part of the batten wide enough to firstly allow the insertion of the network to the cradle and secondly the passage of the protruding bead of the roof module.

• Dans le cas où le support reçoit deux réseaux, par les deux berceaux et la cuvette.
• Dans le cas où le support ne reçoit qu’un réseau, par le berceau, la cuvette et le pan de glissement.

The gorge is delimited:

• In the case where the support receives two networks, by the two cradles and the bowl.
• In the case where the support only receives a network, through the cradle, the bowl and the sliding panel.

The bowl is the lower part of the groove which can accommodate a fixing if necessary and which can channel the condensates.

The cradle is the hollow location located under the throat, it forms a lateral recess intended to receive the heat transfer network. This cradle is understood as a cavity, a compartment, or a chamber which forms the receptacle of the network.

The cradle is characterized by its partially elliptical shape which can be extended in the continuity of the corresponding geometric ellipse.

It has a shape which echoes the elliptical lateral profile of the network.

The cradle is characterized by its partially elliptical shape which follows the heat transfer network and blocks its rotation in the support when the protruding bead located under the roof module is introduced.

Once the network is positioned in its cradle, the groove forms the female part which is the location for receiving the protruding bead of the modules.

Said support is intended for fixing the network and the modules on the frame, comprises a base extended by two walls.

Said support comprises at least one cradle which receives the heat transfer network.

The support is characterized by the cradle which holds the network within it and blocks the expulsion of the module towards the outside.

Even in the event of network overpressure, the movement takes place laterally and cannot expel the roof module upwards. On the contrary, this pressure will tighten the module until the support or network breaks.

The support will be sized to meet these constraints in particular by using a suitable thickness and material.

According to a variant, the partially elliptical shape of the cradle extends on both sides to frame the heat transfer network. This extension makes it possible to keep the network blocked before the introduction of the protruding beads of the roof modules.

This extension of the cradle allows its opening to be closed like a jaw.

Thus, according to this variant, the cradle is characterized by its opening which forms a jaw whose closure forces the network to remain in position, the jaw encloses the network and blocks it.

In this case, the network is held in the cradle of the support by the partial closure produced in the profile of the support by the extension of the cradle.

This particularly advantageous embodiment makes it possible to position and block the heat transfer network while waiting for the installation of the roof modules without risk of accidental movement.

Thus, the partially elliptical hollow shape of the cradle can be extended to better maintain the heat transfer network and pinch it.

According to this variant of the invention, the cradle is characterized by its opening towards the groove of the support which forms a jaw whose closure forces the network to remain in position.

According to another particular embodiment, the supports can also be incorporated into a panel which will be fixed to the frame.

According to this particular embodiment, the support(s) are incorporated into an under roof, they are made of a material different from that chosen for these panels.

It is thus possible to use specialized materials adapted to the functional characteristics.

As a non-limiting example, this incorporation technique makes it possible to combine a flexible or fragile, breathable and good thermal insulating material for the production of panels with supports whose mechanical resistance is higher.

The incorporation consists of the factory assembly of the supports in dedicated locations within the under-roof panels before their movement and installation on the roof, which gives a two-material appearance.

As a non-limiting example, the fixing of this incorporation support can be carried out hot, by overmolding, by clipping, or by gluing.

The advantage of this embodiment is that it allows sarking and preparation of the roof to receive the device according to the invention.

This is an advantageous prefabrication method for making the construction dimensions and spacings between supports more reliable.

According to another particular embodiment, which is called integration, the supports can be made by hollow profiling of the panels which will be fixed to the frame, but also by shaping a panel.

As a non-limiting example of an embodiment, said profiling can be carried out by removing material from the panel by routers.

The supports are integrated into an insulating panel allowing the renovation of the roof from the outside using the sarking method.

Unlike built-in supports, built-in supports use the same material as that of the under roof.

The supports share between them the lateral holding edges as well as the base positioned on the frame.

This particular method makes it possible to industrialize the production of panels for roof renovation by providing thermal recovery, insulation and safety in the event of bad weather.

Indeed, in the event of bad weather such as hail, covering materials such as tiles can be broken or missing on the roof with often significant delays for expert visits and roof repairs; the protection of an under-roof panel allows you to wait out of water for the intervention of companies.

Thus, this invention makes it possible to remedy the disadvantages posed by previous techniques and is intended for the production of roofs whose vocation becomes mixed. Both traditional for creating a beautiful roof; but also the valorization of free energy contributions present in a privileged manner in the upper part of buildings. It is part of the urgent need to reduce our energy consumption for building needs and at the same time our carbon footprint.

Thus, it is possible to present a particular embodiment:

The thermal recovery module takes the form of a traditional terracotta tile made by molding and also includes a protruding male bead under the exposed pureau.

The support is made from suitable wood, starting from battens whose profile is formed by removing material with a series of routers.

The heat transfer network is extruded from elastic and flexible thermoplastic materials of the PP-EPDM type with an elliptical outlet section, then packaged on a reel.

On the roofing site, the support is screwed to the frame like ordinary battens.

Then the network is installed in the cradles and follows the determined route which includes turning curves to pass from one row to another on which the roofer places a sheath which maintains a circular section.

Then, the network is connected at both ends to feeders which can group together other loops.

The roof modules are then positioned on the supports and sunk in the order of producing a tiled roof with their beads facing down which are placed in lateral contact with the heat transfer networks.

The tiles heat up with the heat of the environment and solar radiation and transmit the heat by transmission contact via the network envelope, to the fluid circulated by a circulator. The heat transfer fluid absorbs the heat destined for the outgoing source which collects it all towards a so-called “water/water” heat pump to use it as a cold source.

The heat pump draws heat from the fluid at its evaporator to power the thermodynamic cycle. On the condenser side, circulation through an exchanger supplies the heating and hot water.

Once the heat has been drawn from the heat transfer fluid, the return feeder distributes the cooled fluid to loop back under the roof and absorb the heat.

Detailed description of the figures

represented

There presents a roof section, on which are arranged the thermal recovery modules (4) which have the appearance of ordinary flat tiles. In this drawing, the exterior appearance of the roof is identical to that of a flat tile roof on the market. The roof section being presented in the manner of a cutaway which reveals different constituent elements of the invention. The support (2) is fixed to the frame (5) in the ordinary way by a fixing such as a screw and receives the heat transfer network (3).

The roof module (4) is positioned on the batten (1) like ordinary flat tiles and the profile located on the underside invisible in this figure, transmits the heat from solar radiation to the heat transfer network (3).

The support (2) allows a glimpse of the network (3) through the groove (11), see also . The heat transfer network (3) comes out of the support and has a lateral turning curve whose circular section geometry makes it possible to avoid bends. To properly maintain this circular section, a sheath (25) is positioned on the network (3).

The heat transfer network (3) is connected with a circular standardized connector (29) to a feeder (28) which allows other loops of the heat transfer network (3) to be collected.

The feeder shown (28) makes it possible to collect three loops, only one of which is connected, the other two orifices are closed by plugs (30). The flow is collected towards the circular heat transfer network (3’) to supply a thermal recovery device such as a heat pump.

There presents the section of the roof section according to the , and makes it possible to distinguish different constituent elements of the invention. The thermal recovery modules (4) have the protruding thermal recovery bead (6) which transmits by conduction the heat captured from solar radiation to the network (3) which is positioned in the cradle (10) of the support (2) . The elliptical heat transfer network positioned laterally on the bead of the module (6) remains in perfect contact thanks to its elasticity and the lateral stress exerted by the support (2).

Other classic cover elements are shown in this figure:

On the one hand, the frame (5) whose various constituents are not limiting and do not constitute the subject of the invention. On the other hand, the cleat (1) for fixing at the top of the tile.

The ordinary fixing (7) which connects the support to the frame is not visible in this drawing; she is represented on the .

Figures 3 represent

There presents a section of the support (2) and its different parts.

The base (16) is positioned on the frame (5) and fixed using a screw (7).

In the lower part of the groove (11) there is a bowl (19) which accommodates the fixing (7) which is introduced through the groove (11).

The two side edges (8) one receive the cradle (10) and the other a sliding panel (24)

There allows you to locate the characteristic areas of the support (2).

Thus the hollow hatched cradle area (12) is intended to accommodate and then maintain the heat transfer network. The area of the groove (13) with less tight hatching delimits the location which allows the network to slide, but also the attachment to the frame (5) as well as the protruding bead of the roof module. The bowl (19) which belongs to the throat is located in its lower part and can accommodate the fixing and collect the condensates. The section has a ventilation opening (26) which connects the two side edges (8), which allows air circulation on the underside of the roof.

The groove (11) intended for the passage of the network (3) then for the passage of the bead (6) allows the modules (4) to be maintained in a fixed position. Said throat has a bowl (19) in the lower part to collect condensate. The frame (5) and the attachment to the frame (7) are not shown, but explained on the

the module (4) and inserted along the network (3) in its support (2). The protruding bead of the module (6) is in lateral contact with the heat transfer network (3), a fixing (9) at the head of the module meets the regulatory requirements for mounting a tiled roof.

Figures 5 represent

presents the detail of insertion of a roof module in contact with the fully elliptical heat transfer network, without repeating the view of the support and the modules explained by other drawings.

Only the protruding part (6) of the roof module is shown to detail the contact zone (17) devoted to the heat exchange towards the heat transfer network (3). A hatched arrow indicates the direction and direction of movement of the truncated roof module (4) and illustrated by its protruding bead (6).

approaching, the protruding bead (6) of the roof module touches the heat transfer network (3) at the contact point (14) at an angular incidence (a) constituted by: the tangent of the network (3) at the contact point (14) and represented by the line (d); and by the tangent to the contact point (14) of the projecting bead (6) represented by the straight line (d').

The lines (d) and (d') intersect at the point of contact (14). The angle formed by the two straight lines and noted (a) is sufficiently acute to allow the downward movement of the bead (6) by the elastic deformation of the network (3) and by its sliding without crushing.

There illustrates the downward movement of the protruding bead of the module (6) and the elastic deformation of the network (3) which allows good lateral contact by the elastic reaction of the network (3).

There illustrates the positioning of the protruding bead (6) of the roof module in contact with the network (3) during its installation, when its depression following the arrow in the drawing is almost complete, which shows the contact zone (17) useful for heat transfer which will result.

represented

There illustrates a variant embodiment of the heat transfer network (3) whose elliptical section is modified on the contact side with the bead (6) to present a better contact space (17) and facilitate the insertion of the protruding bead (6).

Figures 7 represent

There represents the cut or elliptical section of the heat transfer network (3) on which the envelope (23) can be seen.

There represents the means of reducing the eccentricity of the ellipse formed by the section of the network (3) when two forces are applied. Thus, the two forces are represented by two hatched arrows which are applied tangentially to the short side of the elliptical section to obtain a reduction in the eccentricity of the section of the network which the operator will accentuate on the .

There presents the achievement of the objective of obtaining a circular section of the network (3) by a simple constraint exerted on the elliptical network following the arrows to make the two foci which characterize the ellipse coincide. The envelope (23) of the heat transfer network (3) allows, through its elastic characteristics, to produce this circular section easily and without breakage.

Thus, the particular ellipse of zero eccentricity is represented (3) in relation to the initial state and intermediate .

There presents the deformation of the section of the network (3) as presented obtained by pressurizing the heat transfer network represented symbolically by the letter P surrounded by arrows.

There presents the network (3) whose section has become circular under the effect of a filling pressure (P) much higher than the shape memory of the envelope (23) of the heat transfer network.

represented

There presents a section of a particularly interesting variant of the invention which increases the contact surface of the roof modules (4) with the heat transfer network (3). The thermal recovery assembly is mounted on a support (2) fixed to the frame (5) by screws (7).

The support (2) has a second cradle (10) by replacing the sliding panel.

Two heat transfer networks (3) are positioned on either side of the groove which accommodates the protruding bead (6) of the roof module (4). Fixing at the module head is carried out by a nail (9) in the thickness of the side edge (8) on the top of the support (2).

represented

There presents the particular case of recovery at the top of tiles (4). The protruding bead (6) of the roof modules (4) located at the head is advantageous for tiles with a large overlap which leave little access to the underside, as for flat tiles with a small mold of historic monuments. Thus the tile (4) has the protruding thermal recovery bead (6) which transmits by conduction the heat captured from solar radiation to the network (3) which is positioned in the cradle of the support (2). The elliptical heat transfer network positioned laterally on the bead of the module (6) remains in perfect contact thanks to its elasticity and the lateral stress exerted by the support (2).

The ordinary attachment of the support to the roof is not visible in this drawing; she is represented on the (9). This fixing connects the supports to the frame (5) whose various constituents are not limiting and do not constitute the subject of the invention.

represented

There presents the section of the particular case of thermal recovery on a channel tile type roof by roof modules (4) which take the appearance of roof tiles.

The tiles (4) receive a protruding bead (6) which transmits heat to the heat transfer networks (3) positioned on the supports (2) which replace the standardized triangular rafters used according to certain installation techniques. These supports (2) are fixed by an ordinary fixing (7) on the frame (5) which in our representation is a purlin.

The support (2) has two cradles to receive two heat transfer networks (3).

The roof channel tiles have a protruding bead (6) on the underside which is inserted into the groove in lateral contact with the heat transfer networks (3). The support also receives on the exterior sides, the current tiles (18) as for a roof with installation on triangular rafters. Thus this support (2) maintains the current tile (18) in the rainwater collection axis. The support rafters (2) being installed with the inclination of the roof, they channel the condensate water which could form along the bead (6) and the networks (3) through a small channel (19). These condensates go down the drain or can be drained towards the current tile (18). In this case, care must be taken to avoid the penetration of humidity through the support (2) towards the frame (5) for example by using a seal under the fixing head (7) or as shown on the right rafter by positioning the fixing (7') on the exterior part of the support (2). This lateral fixing position external to the support (2) leaves the passage of the small channel (19) located under the protruding bead of the modules (6) free and eliminates the risk of corrosion of the upper part of the fixing (7).

Figures 11 represent

There represents a case of recovery on a metal roof. The thermal collection support (2) is made in the battens usually located on these metal covers. The battens (2) are positioned on the frame (5). Thus the support (2) includes the characteristics of the invention with two heat transfer networks (3).

The metal bead (6) is produced at the lateral end of the covering sheets by stress forming using a beater or folder. Thus formed, the metal sheet becomes the roof module (4) intended to collect the thermal flow. The expansion of the metal sheet (4) is allowed as usual by the space located at the foot of the cleat in the extension of the base (16) of the support (2). The support cleat (2) is fixed to the frame by a conventional fixing (7). Specificity of the metal, as it is thin, it is possible to successively insert two sheets one on top of the other at the level of their protruding beads (6), destined for the groove (11) of the support ( 2) as indicated by the arrows. The first module (4) has a recess (31) on the rear part of the bead (6) intended to receive the second module (4'). Thus two modules (4) are nested one on top of the other at the level of the protruding bead (6) on the same support cleat (2). The left and right metal sheets of the roof are then brought into mutual contact in the groove (11) before receiving protection by the waiting joint cover (21).

There illustrates the final assembly carried out according to Figures 11 with the final installation of the joint cover (21) on the assembly. Thus the two modules or metal sheets (4) and (4') are represented in contact with one another by the interlocking of their beads (6). The network (3) is then put under filling pressure and causes a crushing of the protruding bead (6), which fixes the metal sheets (4) and (4') like a clamp, replacing the cleated tabs. This technique is also not incompatible with the cleat legs through openings made by perforating tools on the upper part of the metal sheet located in contact with the cleat (2). The tab is then folded down through this opening (not shown). Thus the left module (4') which by its covering function and its ordinary appearance will be called the left roofing sheet is nested in the hollow formed by the right roofing module (4) or right roofing sheet. The pooled heat flows supply the two heat transfer networks (3) located in the cleat (2). The cleat is fixed by a classic fixing (7) to the frame (5).

Figures 12 represent

There illustrates another mode of use of the invention by thermal recovery on the underside of metal sheets. Two techniques are shown to demonstrate the use of an insulating panel.

The first technique consists of directly integrating the supports (2) into the panel. For this, the panel must be sufficiently dense and mechanically resistant to allow it. Thus, several supports (2) are here made hollow in a panel which advantageously combines insulating qualities, protection against condensation, and rigidity. The cleat (1) is that of the usual metal covers for separating and fixing the metal sheets (22). Said batten could also be integrated into the panel (27) and allow thermal recovery as shown in Figures 11. This panel which includes the supports (2) is a sarking panel (27). This allows renovation of the roof from the outside of the frame (5) as with market sarking.

Thus the supports (2) are integrated into the Sarking panel (27) at the time of its production in the workshop.

They present the cradles (10) to receive the heat transfer networks (3) which are positioned in a first installation time (t1) by its introduction through the groove of the support. Then, the roof module (4) which takes the form of a fin here made of metal will allow the mediation of the thermal flow received by the ordinary roofing sheet (22) intended for the protruding beads (6).

This roof module is pressed onto the support, second installation time (t2), and is positioned in lateral contact of the two networks (3) by its bead (6). Finally, the operator in the third installation phase (t3) positions the roofing sheet (22) between the two ordinary battens (1) and in contact with all the roofing modules (4)

The second technique consists of incorporating a support (2') into the panel. The panel does not need to have the rigidity characteristics necessary for integration.

The insulating panel can thus be made of a natural material whose strength and mechanical resistance are lower. The panel is produced for example by compressing a location intended to receive the support (2'). The independently made support is positioned on top. The rest is identical to that of the panels with integrated support which also allows renovation of the roof from the outside as with the sarking on the market and using different types of insulation. The condensation at the level of the networks can be collected in the lower part by the channel (19) towards the drain of the roof section.

represented

There represents a variant of the innovation of creating an under roof. This embodiment is advantageous in particular, and without this example being limiting, for protecting the home in the event of damage to the tiles or the exterior covering by hail. The supports (2) are made in a prefabricated panel (20), which forms an under-roof, fixed by ordinary fasteners (7) and allows it to be associated with an insulating panel (32), the latter being itself even attached to the frame (5), this classic attachment between the panel (32) and the frame (5) is not shown.

represented

There represents another variant of the innovation which makes it possible to create an under-roof intended for canal tile roofs. The under-roof panel (20) integrates the supports (2) on the top of the convex part. The under roof is fixed by ordinary fixings such as lag bolts (7) which pass through the upper part of the wave towards the frame (5) by first crossing reinforced bridges (33). This sub-roof (20) ensures the protection of the roof against the penetration of water and facilitates implementation.
