® DEVICE OF EQUIPMENT FORMING AN ENERGY COMPLEX.

FR 3 062 196 - A1 (57) The invention relates to a device for equipment forming an energy complex and comprising external surfaces corresponding to pedestrian and traffic lanes, play areas and vehicle parking, characterized in that he makes,

- a cemetery, the covering of the paths of which is suitable for moistening the ground in which a geothermal device is integrated,

- a sports field, the covering surface of which forms a permeable upper layer of a geothermal installation capable of ensuring a sufficient level of humidification of the ground,

- an outdoor car park, capable of channeling the rainwater collected towards geothermal material burial spaces, the equipment being able to be independent or linked to each other, each equipment defining a storage area for installations and materials intended to produce energy, the regular functioning of the energy complex being ensured by the conjunction between on the one hand outdoor spaces whose coating is permeable and on the other hand the installation of photovoltaic and aeraulic materials.

The present invention relates to a device for equipment forming an energy complex for the installation of equipment for producing energy, heat and freshness.

In particular, the invention relates to an equipment device integrating a set of installations and materials for the recovery of energy, heat and cold. The device is designed in such a way that each item of equipment is, if necessary, connected to at least one other item of equipment or to at least one construction, the communication channel and the buried networks connecting the items of equipment to each other and to buildings dedicated to the housing, industrial and tertiary activities. The system is set up across the city to ensure the proper functioning of urban areas and meet the energy and storage needs of living quarters.

In the field of spatial planning and energy, it is common to build separate equipment separately which does not include a set of installations for the production of energy and the storage of materials.

More generally, in large cities and urban centers, certain facilities offer large areas dedicated exclusively to a specific activity.

Today, more and more cities are expressing the desire to develop equipment in their districts that includes recovery and production units for energy, heat and cooling. To meet the needs of neighborhoods, it is a question of installing these facilities near places of life and activities. However, such complexes require large spaces, free of construction or associated with new construction programs.

Unfortunately, in dense urban areas land reserves are becoming increasingly scarce and land very expensive. With the exception of municipal sports grounds, cemeteries and outdoor parking areas, there are few large rights-of-way in town that can accommodate similar facilities. Likewise, it would not be acceptable to replace sports grounds, cemeteries or outdoor parking spaces with energy and storage equipment. Indeed, the disappearance of such spaces would generate inconvenience for the municipalities and their inhabitants.

The invention therefore aims to allow the reconversion of funeral, sports and parking spaces by proposing to develop a system of energy equipment, civil engineering works and networks at the location of cemeteries, land municipal games and adjoining car parks simultaneously combining sports, parking and energy production.

The aim is also to design multifunctional equipment devices, associating energy production facilities and equipment with the lawn areas of sports fields, the pedestrian walkways of cemeteries and the outdoor spaces of parking lots. These devices would be arranged to produce energy from the sun's rays and the force of the prevailing winds. They would also consolidate the pooling of public equipment needs, as well as the storage, treatment and recovery of the heat and freshness contained in the soil. The initial investment inherent in the development or construction of such equipment and the installation of installations and networks of cables and pipelines would ultimately promote the subsequent economic profitability of the sites developed. Indeed, beyond the period of realization of these works, the equipment would eventually offer proximity services to the districts and would produce heat, cold and energy for the inhabitants. Such a multifunctional and energy system would make it possible to reconcile investments in equipment installations with the challenges of an energy transition in an urban environment.

In particular, the invention relates to an energy production unit integrated into a sports field, a cemetery and a parking area partially or totally fitted out for the installation of energy production equipment, the sports field, the cemetery. and the car park comprising a set of energy production facilities and equipment distributed over different areas of their outdoor spaces, and in particular play areas, pedestrian walkways, funeral spaces and car park walkways.

The sports ground, the funeral space and the parking lot are intended for the energy, leisure and meditation sectors. They would also make it possible to design energy production equipment adapted to the development of cities and the territory. In the same way, they would favor the construction of units of production of electricity, cold and heat, external or semi-buried in the big cities where the free grounds of constructions are few.

The invention therefore relates to a device for producing energy, characterized in that each piece of equipment constitutes at least one sports ground, a parking lot or a cemetery, each piece of equipment incorporating at least one energy production unit, corresponding to a geothermal installation to which can be added a photovoltaic installation and a wind-type installation.

In general, the whole set of equipment and the installations constitute energy production areas, the power of which depends on the surface area of each piece of equipment and its spatial organization.

The present invention also relates to an energy production process obtained by fitting out three separate pieces of equipment,

- a playground reserved for the practice of collective or individual sport such as football, rugby, tennis or equivalent,

- a car park for parking vehicles,

- a cemetery dedicated to the organization of funeral spaces, each piece of equipment comprising at least,

- a wind installation located on its periphery and more punctually on its internal footprint,

- a geothermal installation located under its central space and nearby,

- a photovoltaic installation positioned on the whole of its surface or more punctually on its periphery, the operation of said equipment admitting buried or external installations.

If necessary, a buried methanization plant can be fitted under the equipment.

The invention therefore relates to a sports field, a cemetery and a parking lot producing and storing energy, heat and cold, characterized in that they constitute a platform arranged and organized in such a way as to ensure collection. and the production of energy in an outdoor space free of construction. These equipments offer large permeable surfaces suitable for geothermal energy. Well exposed to the prevailing winds and the sun's rays, they are also suitable for installing solar, photovoltaic and wind energy equipment.

In the field of energy, it is common to build various equipment (sports grounds, datacenter, sorting center, urban logistics center, methanization unit, geothermal power plant ...) in specific places, this equipment being spread across urbanized neighborhoods. Generally, these constructions, intended for certain activities and for the production of energy, are bulky and expensive. They are generally located on large lots very far from city centers, business districts and residential areas. Likewise, this equipment does not make it possible to create compact structures which group together several energy and storage installations on the same site in the heart of residential areas, for example.

The object of the invention is to propose a device for rapid equipment to be fitted out and offering municipalities the possibility of producing their own energy on large municipal areas. The goal is also to design sports, funeral and energy complexes that are inexpensive to build and maintain. Energy production would generate income to maintain the playgrounds and funeral spaces.

The initial investment will be amortized in a few years, the municipalities profiting from the presence of free spaces of constructions, capable of ensuring a partial energy autonomy, in particular in dwellings, in public facilities and in businesses located nearby.

More generally, the establishment in town of such equipment devices would be an advantage in reducing pollution and noise. Indeed, they would facilitate the constant supply of energy to a large number of electric charging stations, while allowing the supply of heat and cold in social housing districts, thus contributing to the development of cities and urban electric transport.

Finally, the invention also aims to promote the provision of sources of energy production and storage near places of life and consumption in order to minimize the distances to be traveled to supply electricity, heat or freshness to the neighborhoods and thus avoid significant energy losses.

Summary of the invention:

To this end, the subject of the invention is an equipment device located in an urban or rural environment capable of producing, storing and transporting heat, cold and energy, characterized in that each piece of equipment forms a unit of energy production comprising at least one geothermal installation to which can be added a photovoltaic installation, a wind installation and an anaerobic digestion plant.

Geothermal installations

The device of equipment forming an energy complex and comprising external surfaces corresponding to pedestrian and circulation aisles, play areas and vehicle parking, is characterized in that it constitutes,

- a cemetery, the covering of the paths of which is suitable for moistening the ground in which a geothermal device is integrated,

- a sports ground, the covering surface of which forms a permeable upper layer capable of ensuring a sufficient level of humidification of the ground to allow the operation of geothermal installations,

- an outdoor car park, capable of channeling the rainwater collected towards geothermal material burial spaces, each equipment defining a storage area and constituting the cover and the envelope of installations and materials intended to produce water energy, the regular functioning of the energy complex being ensured by the conjunction between permeable outdoor spaces and the installation of photovoltaic and aeraulic equipment.

The energy present in the earth can be recovered, from boreholes or production and reinjection wells, heat, cold when the wells are very deep. The generators thus supplied run an electrical network. The system includes a sports ground and / or an outdoor car park and / or a cemetery, where applicable all three connected, the whole constituting the cover of a geothermal installation distributed occasionally or globally under the sports ground, its surroundings , the parking lot and the cemetery. The operating principle of the installation consists in using the earth's natural energy resources, by capturing the calories present in the soil by exchange with a refrigerant, always colder than the earth. It is then a question of recovering this energy by transforming it into electricity, heat or freshness usable for nearby houses or buildings, in the form of heating made up of a generator using the quantity of electricity necessary for the transfer.

The geothermal installation accepts three different energy capture systems.

In a first embodiment, the buried tubular collectors are horizontal and consist either of one or more loops distributed in the form of a U at a short distance from each other or in a spiral type of geothermal baskets or equivalent. These sensors are positioned at a shallow depth and connected to heat pumps, the heat from the ground then being transmitted to sensors by means of a mixture of water and antifreeze in a closed circuit. The generator alternately evaporates and condenses its refrigerant to heat either the water from the radiator network or the water from transmitters and floors.

In a second embodiment, the catchment is vertical and admits geothermal wells and boreholes. The boreholes contain pipes, most often made of polyethylene arranged in double U and coated with a cement grout ensuring their mechanical protection while allowing a certain flexibility essential to resist ground movements. All the wells thus form a field of probes installed in loops and spaced apart to limit the thermal interfaces. The probes are connected to each other by manifolds distributed in series, in parallel or a mix of the two. The field of probes can be placed nearby, around, or under the sports field, parking lot and cemetery. There are coaxial probes, the water coming from the buildings circulating in the peripheral part of the probe and returning through the heart of the probe to deliver in return its energy to the same buildings. To increase the heat exchange with the ground, the probes are made of steel or stainless steel without coating, the peripheral tube being made of metal and PE in its inner part.

In a third embodiment, the geothermal system consists in directly drawing the water from the groundwater without resorting to an exchanger and a heat transfer fluid. In this solution, the water in the aquifer serves as an exchanger in heating mode and as a cold source for a heat pump, or in cooling mode and as a direct cold source for a water loop. In winter, a zone is cooled by the water reinjected after exchange with the heat pump, in summer the water is pumped in the opposite direction from this zone and reinjected warmer into the winter draw-off zone. In addition, it is also possible to produce hot and cold at the same time under the equipment. In fact, if necessary, the water pumped from the aquifer can be directed both to the heat pump and to the geocooling exchanger or to a common exchanger between the production of hot and cold.

Depending on the needs, it is possible to install different technologies.

The first technology, with direct expansion proposes to ensure the transfer of heat by refrigerant in closed circuit contained in the network of tubular sensors. In this configuration, the external sensor constitutes the evaporator and the floor heating the condenser, for example. Evaporation and condensation are done gradually for better efficiency. The compressor and regulator are installed in a technical room located under or near the equipment and the sports field. Several compressors can be used to heat different areas of neighboring buildings at variable and suitable temperatures. This system offers optimum performance for a minimum collection surface.

The second technology, with brine, recommends transferring the useful heat by hydraulic distribution circuit with a network containing brine in the horizontal or vertical collectors and water in the heated floor. Independently of the compressor and the pressure reducer, the generator consists of two exchangers where evaporation and condensation take place, thereby releasing sufficient energy to heat the water. It is also possible to use a network of radiators in place of the heated floor. In this technology, the collection surface is large. However, in order to reduce this surface, it is possible to install, in addition, vertical sensors, of the geothermal probe type or equivalent, which penetrate more deeply into the ground.

The third technology, by drawing water, consists in transferring heat by means of the water taken from the groundwater and by a hydraulic circuit. The generator consists of a compressor, a plate exchanger and a spiral plate exchanger. The heat pump thus uses the energy recovered by the water taken from the well to efficiently heat the buildings. Water is thus taken from the ground at around 10 or 20 meters, ensuring a constant temperature all year round and optimum performance of the heat pump.

In the fourth technology, mixed, a refrigerant is used for the sensors and a hydraulic circuit for the heated floors or the radiators of the constructions. Evaporation takes place directly in the external sensor. The release of energy to heat the water is ensured by a generator itself composed of a capacitor.

Photovoltaic and wind solar installations

In the wind production mode, installations of the wind turbine boxes, wind panels or turbines on masts are arranged around the sports field, for example, in such a way that the materials do not impact on the practice of collective or individual sports. The play area, the parking lot or the cemetery each comprise on at least one of their sides and at their periphery a set of boxes, screens and masts provided with turbines, the whole forming energy production units consisting of wind turbine equipment. In this solution, each box or each panel comprises a set of perforated drums acting as turbines. Boxes and panels wired and connected to alternators and inverters are thus formed and installed in horizontal, vertical or oblique positions to facilitate the installation of gripping surfaces of prevailing winds over great heights. The installation along sports fields of large screens provided with boxes and wind panels, offer several advantages with regard to the use of the force of the winds and the absence of obstacles located nearby. Indeed, the free sports area of constructions defines an open space well exposed to the winds. The air masses can thus move freely and reach high speeds.

When the installation is solar photovoltaic and thermal, equipment such as a sports field, parking lot and cemetery can be used to create sets of inclined screens intended to capture the sun's rays to produce electricity and hot water. In a particular embodiment, the periphery of the sports field can constitute a large surface designed to produce energy from the sun's rays. In this configuration, the photovoltaic and thermal panels are distributed in series. Differently, the play areas and the central part of the sports field can also incorporate a floor covering designed to generate electricity from micro-photovoltaic cells. These micro-cells form filaments attached to a flexible support, the general appearance of which is similar to grassed surfaces. In another variant, the microcells admit silicon particles embedded in the thickness of the floor covering constituting the photovoltaic support of the play spaces and of the central part of the sports field capable of producing electricity.

Anaerobic digestion plants

Because of its large surface area, the equipment system constitutes an energy and multifunctional complex forming the envelope for the development of buried installations of the central anaerobic digestion type distributed under the free surfaces intended to accommodate parking lots or areas reserved for the practice of sport, the whole complex comprising at least:

- a cemetery comprising a landfill suitable for receiving an anaerobic digestion plant,

- a sports field defining the upper part of a waste treatment and anaerobic digestion plant,

- an outdoor car park defining the upper envelope of a civil engineering structure, each piece of equipment constituting the envelope of energy production installations and equipment, the regular and continuous operation of the complex being ensured by the conjunction of areas landfill and buried structures designed to develop a waste recovery and energy production plant.

In this embodiment, the sports field, the cemetery and the parking lot each constitute a climatic volume containing the envelope of the methanization plant, the management mode of which will make it possible to recover and produce energy. For example, with the development of needs, an increasing quantity of household waste must be stored and recycled. To this end, more and more new waste treatment and recovery centers are being set up in cities. Advantageously, the biogas released by anaerobic digestion equipment (storage tanks, sorting center, digestate, basins, etc.) can be recovered and then stored to produce energy, heat apartment buildings, offices or equipment. municipalities in neighboring districts. The landfill area, ¹¹ envelope and floors of the work in civil engineering are fully enrolled in Climate volume. The floors define, for example, the storage media for tanks, the landfill area of the sports field being designed to directly use the temperature of the basement to promote the regulation of the air masses of the plant.

The invention also relates to a sports field, a cemetery and a parking lot defining additional energy devices capable of producing electrical energy, heat and freshness.

In a second embodiment, the sports field and its external areas define the support of a flexible or rigid photovoltaic coating, capable of producing electricity. The coating composed of photovoltaic cells has plates distributed in such a way as to promote their performance. In this configuration, the sports field is partially or completely covered with photovoltaic coating. This embodiment also allows the reuse of the flat surface corresponding to automobile parking areas. Similarly, it is possible to complete the photovoltaic device on the ground by installing farms and photovoltaic and thermal solar panels on the outskirts of the sports field and near the playgrounds. Hybrid solar panels can be integrated into installations to ensure mixed photovoltaic and thermal solar production. In this case, photovoltaic sensors are placed to collect solar energy on the panel and thermal sensors on the second layer of the panel to provide both electricity and hot water. These facilities will promote good performance and will be located in shaded areas, free of plantings and buildings.

In another embodiment, the sports field and its outdoor areas include a wind device designed to generate the production of electricity, said sports field being able to form a wind field arranged to ensure the recovery of the prevailing winds around the areas of games. In order to facilitate the operation of a wind turbine unit, the sports field also includes within its perimeter, or near it, different types of turbines and turbine boxes. In this solution several types of wind devices can be associated: helical, drum, propeller or high wind turbine on mast.

Depending on its footprint and its surface, the sports field brings together one or more energy production units based on different recovery and heat and energy production modes (geothermal power plant, boxes and outdoor wind screens, panels photovoltaic solar panels and hybrid panels, underground methanization unit ...). In this case, when the sports field forms one or more equipment storage and energy production units, integrated into several of its spaces forming its structure and organization. In this configuration, the sports field then constitutes mixed energy equipment.

In another embodiment not illustrated, the sports field and its external areas constitute the cover of a buried parking lot inside which vehicles are parked. In this variant, the car park forms a civil engineering structure comprising a slab. The structure is provided with foundations and geothermal piles located below its lowest floor. The underground structure also includes access ramps located outside the limits of the sports field in such a way that access to the car park is independent and does not impact on the playgrounds and their configuration. In this arrangement, the sports ground defines outdoor spaces designed simultaneously for sports, energy production and vehicle storage, the entire car park being buried or semi buried under the surface of said sports ground. The parking envelope may include at least one watertight water tank intended for the storage of drinking water and the recovery of rainwater to allow maintenance and watering of playgrounds and the sports complex. .

In another embodiment which can be complementary to the sports field, the parking lot constitutes an energy production area on which and under which are vertically and horizontally distributed energy production devices and materials capable of producing electrical energy, heat and freshness, characterized in that the parking lot constitutes a platform comprising storage spaces for geothermal, wind and solar photovoltaic materials;

- the first space corresponding to the parking spaces intended to constitute permeable spaces capable of supplying the ground with water and ensuring the functioning of the geothermal installations,

- the second space corresponding to the traffic aisles of vehicles designed to be covered with a flexible or rigid floor covering comprising photovoltaic cells,

- the third, admitting parking spaces and aisles for vehicle circulation at the periphery of geothermal, wind and photovoltaic installations.

In general, the installation and distribution of the various materials consists of positioning additional energy production devices on and under the outdoor parking area.

Graveyard

Another preferred embodiment proposes to fit out under a cemetery a geothermal device, if necessary complementary to the geothermal installations located under sports fields and parking lots, said cemetery admitting on its periphery a set of wind and solar materials capable of producing energy, characterized in that it comprises different sectors which can accommodate installations,

- the first sector corresponding to pedestrian and traffic paths,

- the second sector defining free spaces for graves,

- the third corresponding to the periphery of said cemetery and offering windy and sunny spaces, the whole geothermal system being supplemented by photovoltaic and wind external installations distributed in the different sectors of the cemetery to produce energy.

The present invention also relates to the IT management of heat, cold, electricity and water flows, distribution of flows and energy transfers within the perimeter of the sports field, its parking lots and its access roads designed to maintain and direct these constant flows and transfers and ensure regular energy production. In general, the energy production process is obtained by the storage of materials and the installation of different geothermal, wind, photovoltaic and thermal materials arranged through a device of platforms forming multifunctional complexes contained inside. sports fields, parking areas and access roads.

Likewise, the invention provides a method of storing, recovering and producing heat, freshness and energy under at least one sports ground, an outdoor parking area and a cemetery. This process consists of distributing large-scale outdoor wind and solar installations over large areas, to which are associated by burial, geothermal capture systems and anaerobic digestion plants, the equipment system forming a vast urban energy complex. .

Detailed description of the invention:

The invention will be better understood, and other objects, details, characteristics and advantages thereof will appear more clearly during the detailed explanatory description which will follow of a particular currently preferred embodiment, given solely by way of illustration. and not limiting, with reference to the appended schematic drawings in which:

- Figure 1 is a plan view of an existing sports field, outdoor parking and a cemetery located close to each other, for example, the entire device device being devoid of energy installation;

- Figure 2 shows the same device in which are arranged different energy production facilities; geothermal, wind and photovoltaic;

- Figure 3 shows the same sports field of the device illustrated in Figure 2, in which is installed at least one collector connected on the one hand to at least one geothermal probe and on the other hand to at least one heat pump.

In Figure 1, there is shown a sports field 1, a parking lot 2 and a cemetery 3 in the form of spaces respectively reserved for sports, parking vehicles and the establishment of funeral spaces. These three urban facilities dedicated to different activities constitute large areas generally free of constructions, said constructions being able to represent obstacles to the prevailing winds and favor the development of gray areas can be conducive to the development of photovoltaic and thermal solar installations. This large equipment is generally located near living quarters and offices.

The sports field 1 has a playground 4 arranged in the central part and a peripheral space 5 corresponding to grassy areas.

Parking 2, located here by way of example near the sports field, is in the form of an area reserved for vehicles and includes parking spaces 6 and circulation aisles 7. The parking spaces are distributed perpendicularly pedestrian walkways 8, organized inside and around the car park.

Finally, a cemetery 3 located near the sports field 1, includes pedestrian and traffic paths 9 arranged in an orthogonal diagram, for example. The cemetery 3 also includes a set of tombs 10 distributed one next to the other. Buildings 18 corresponding to apartment buildings and offices are located near the device or at the limit with the equipment.

In FIG. 2, a sports field 1 is shown with energy production and material storage units comprising on its surface a set of external materials arranged one next to the other so as to form one or more production devices. of energy. In the embodiment shown in this figure, the surface of the sports field 1 constitutes partially or totally the support and the cover of a set of devices in which alternate at least one geothermal device 7, 8, 9 and equipment type 7 production and reinjection 8, probes and boreholes 9, geothermal baskets or horizontal device arranged in a serpentine pattern, and on the other hand a wind device 11,12,13,14,15 and a solar device and photovoltaic 16,17, the wind and photovoltaic equipment being distributed around and near the sports field 1, and on the interior and exterior right-of-way of its parking lot 4. In the embodiment represented in FIG. 2, a device for geothermal, 7, 8, 9, if applicable reversible, is arranged under and / or next to the sports field 1. The geothermal device comprises, for example, at least one production well 7 and a re well injection 8. The entire device is connected and if necessary incorporates a geothermal power station 10 located near the wells. To bring the energy to the surface, the hot water accumulated in the earth is extracted from the aquifer or deep aquifers using at least the well 7 intended to collect the water and the well 8 able to reinject the water in the water table. The production well 7 is used to draw water naturally heated to around 70 ° C in the basement, to a depth of up to more than 1,600 m or a few tens of meters when the water table is shallow . The water will be routed in such a way that its heat is transferred to the district heating circuit or to buildings 18. An auxiliary boiler room will complete the system, to meet all the needs of the network, or in case of emergency . Thus, the water in the basement transmits its heat through the exchanger of the heating circuit.

In a variant not illustrated, the collection is horizontal. In this configuration, juxtaposed and if necessary superimposed horizontal sensors are distributed under and / or around the sports field 1, the device being buried at shallow depth. Depending on the technology used, glycol water is contained in the tubes of the tubular collection device, the refrigerant of the heat pump circulating in a closed circuit inside these tubes, the entire collection device s' organizing substantially in a serpentine pattern from collection loops and maintenance manholes. For maintenance of the horizontal device, external hatches positioned on the surface of the sports field constitute direct access to the sensors. For the sake of integration into the playground and adaptation to the practice of a football or equivalent type of sport, the hatch is covered with grass or a synthetic or equivalent floor covering in order to be light visible on the playground.

To complete the energy supply of the sports ground 1, a wind power device 11 is installed around the said ground and its playgrounds. Indeed, a set of wind boxes 11 and wind panels 12 are superimposed and juxtaposed to structure sets of vertical and horizontal screens 14 and 15 defining gripping surfaces of the movements of air masses. In the solution in which the wind device integrates modular wind turbine boxes 11, the assembly constitutes a cellular surface, each box forming a cell. In this configuration, the boxes 11, hollow, are stacked and superimposed and define in their central part an empty space inside which is installed at least one turbine of helical type, twisted or equivalent. The box 11 also has inclined inner edges according to a funnel diagram capable of promoting, by the venturi effect, the acceleration of the air masses inside the box and through its hollowed-out central space. In another variant, the wind device comprises wind panels 12 capable of constituting vertical screens organized and mounted from the assembly of said modular wind panels, fixed to each other. These wind panels 12 are fixed to each other, vertically and horizontally by means of a system of rigid sections 13 capable of ensuring their stability and the bracing of the general structure of the wind screens. Thus, each box 11 and each wind panel 12 defines a surface in which alternate wind turbines and empty spaces contained inside said boxes and said panels. The wind screens are arranged differently depending on the direction of the prevailing winds and oriented perpendicular, parallel or oblique to the sports field. The device of the boxes and wind panels is connected to at least one alternator. Wind screens have a low noise impact and can be easily installed at the edge of the sports field. Other types of wind installations and equipment complete the wind screen system, in particular helical, twisted or equivalent turbines mounted and installed on top of masts arranged around the sports field 1, playgrounds, parking exterior 4 and cemetery 3.

In the embodiment shown in this figure, the surface of the sports field 1 forming the cover of geothermal devices, partially or totally constitutes the support of a device in which alternate types of photovoltaic materials alternate. Indeed, the surface of the sports field 1 and the vehicle parking area 4 comprise a floor covering 17 capable of producing energy from the rays of the sun. In this configuration, the flexible and permeable floor covering constitutes a surface capable of producing electrical energy. The support for the floor covering comprises photovoltaic micro-cells of the filament type or equivalent fixed in the manner of synthetic turf to the flexible or semi-rigid films forming the thickness of the covering and its holding structure. In addition to the photovoltaic micro-cells, the support incorporates in its thickness micro-perforations capable of letting water pass and channeling it in such a way as to humidify the subsoil and favor the functioning of the geothermal device. The entire surface of the sports field is photovoltaic, and may also include a flexible synthetic coating of rigid asphalt, semi-rigid or flexible comprising photovoltaic cells embedded in the thickness of said asphalt to form a paving and production slabs. of electricity.

Near the sports ground 1, the parking area 4, also admits a geothermal device 7,8,9, probes, production and reinjection wells, geothermal baskets or horizontal sensors. Likewise, it comprises a floor covering 17, made of coated material or of rigid, semi-rigid or equivalent synthetic material, comprising photovoltaic micro-cells designed to form particles for producing electricity embedded in the thickness of said coated material capable of form a paving and slabs of electricity production. The sports field 1 and the parking area 4 define a photovoltaic unit for producing electricity intended to supply electricity to the surrounding buildings 18 or to public lighting. Regardless of the photovoltaic, flexible or rigid floor covering, photovoltaic, thermal 17 or hybrid solar panels are fitted on at least one of the sides of the sports field 1 and the parking lot 4.

The equipment system is supplemented by a cemetery 3. The energy and multifunctional complex includes the pedestrian walkways of the funeral spaces generally installed near a sports field 1 or an outdoor car park 4. The cemetery 3 of variable shape includes pedestrian walkways generally arranged parallel and perpendicular to each other. This arrangement is suitable for installing buried and geothermal equipment 7,8,9. A set of geothermal probes 9 integrated into boreholes are thus distributed at regular distance under the floor covering of the pedestrian walkways which are also designed to receive maintenance vehicles. To promote the proper functioning of the geothermal device and the probes 9, the ground must be moist. For this reason, the pedestrian walkways allow permeable flooring of stabilized type or equivalent. Other geothermal materials can supplement the device or replace the probes 9. In this case, geothermal baskets or horizontal devices of tubular collectors distributed according to a serpentine scheme will be installed at shallow depth and connected to collectors and pumps heat. The permeable surface of the cemetery will form a vast geothermal complex. The graves 19 of the cemetery 3 and their alleys will admit at their periphery a network of boreholes, probes and geothermal baskets placed next to each other to form a mesh network across the cemetery 3.

In Figure 3, there is shown the geothermal installation located under the sports field 1, whose embodiment, shown here and by way of example, admits a vertical collection system, the sensors being buried and composed of one or more geothermal probes 9 integrated into a borehole or geothermal baskets formed in cavities. The probes 9 distributed at regular distance from each other, in a straight, orthogonal or staggered pattern form a field of probes. The probes 9, filled with a mixture of liquid (glycol water, etc.), are connected to at least one collector 20 itself connected to at least one heat pump 24 of variable power. In this solution, the vertical geothermal probes 9 positioned in staggered rows with respect to each other are arranged below the level of the sports field 1, in a borehole, and sealed. The depth of these probes can reach several hundred meters, in order to reach the depths of the ground where the temperature is stable throughout the year. Several collectors 20 are buried near the probes 9 and admit an outgoing circuit 22 and a re-entering circuit 23, both connected to a heat pump 24. To ensure maintenance of the device, external inspection hatches are positioned above the collectors 20, on the surface of the sports field 1. For the sake of integration into the playground and adaptation to the practice of a sport of football or equivalent type, the hatch is covered with grass or synthetic or equivalent flooring suitable for being invisible on the playground and not constituting an obstacle.
