    Title: Solar collector site The present invention relates to a site provided with a device for absorbing solar heat, in particular a so-called solar collector site, more in particular a solar collector sports field. At least part of the surface of the site is designed for heat recovery. The site is suitable for connection to an installation for extracting energy from heat, for example a geothermal installation or an installation for converting thermal energy into electrical energy. The invention further relates to a method for recovering heat from a solar collector site. Various solar collector sports fields are known from the prior art.
    NL2015181B relates to a substructure for a sports field, which substructure is suitable for the storage and transport of heat and cold. The sports field has a top layer with synthetic fibres. Three sublayers can be distinguished under the top layer, i.e. a first sublayer with fine grain-like material, a second sublayer with a coarser grain-like material and an adjacent third sublayer designed as the first sublayer. Below the third sublayer is a water-permeable shock-absorbing layer provided with recesses such that tubes are substantially received in the recesses. The tubes are at a mutual distance of at least 20 cm. A heat or cold conductive liquid can be pumped through the tubes. Below the shock-absorbing layer is furthermore a drainage layer with drainage pipes. The sports field is box-shaped and closed at the bottom by a housing that is provided with a layer of insulation material on the inside. Temperature sensors are fitted at various positions. A temperature sensor has been placed on the artificial grass and a temperature sensor is also located in the substructure. Furthermore, a temperature sensor is placed in front of the water inlet. FR3044696A describes a sports complex with a sports field and a geothermal installation for recovering and producing heat and energy. The geothermal installation is contained in hollow spaces. The sports field forms the cover of the geothermal installation with geothermal wells and cavities for geothermal collection.
    A drawback of known solar collector sports fields compared to a sports field without the possibility of heat recovery is that the investment is relatively large.
    The payback period for a solar collector sports field is therefore long.
    Because sports fields quickly involve large surfaces, it is desirable to find an embodiment of a solar collector sports field which is simple and efficient in terms of construction, so that the construction of a sports field becomes cheaper.
    Sports fields are usually managed by associations, so it is important that an investment for a sustainable solar collector sports field fits within a limited available budget.
    A simple embodiment of a solar collector sports field that can be installed for an attractive price ensures that a sustainable solar collector sports field is within reach for more associations.
    In addition to sports fields, it is known to extract energy from roads.
    Ooms Products is a company that builds roads with cold/heat storage.
    Road Energy Systems® extracts energy from asphalt.
    The system consists of an asphalt solar collector with which energy is buffered in the soil by means of cold/heat storage, and can then be used for, for example, heating and cooling buildings.
    The asphalt solar collector is fitted with a pipe system.
    The tubes take heat and cold out of the way.
    The pipes are placed with a center to center distance of approximately 15 cm in an asphalt underlayer of approximately 60 mm.
    The pipes are positioned at a distance in a plastic mat that is embedded in the asphalt substrate.
    The fixation of the tubes is described in the application EP1134502. The object of the present invention is to at least partially obviate at least one of the above drawbacks or to provide a useful alternative.
    In particular, it is an object of the invention to provide a sports field for supplying heated water to a solar collector installation, wherein a large surface of the sports field is provided with a device for recovering heat without appreciable expense.
    This object is achieved with a solar collector site according to claim 1. In particular, the site concerns a sports field, a sports field.
    It should be noted that a sports field is to be understood hereinafter in the broad sense of the word as a terrain that is arranged for practicing a sport, such as a football field, hockey field, tennis court or an athletics track.
    The site is at least partially designed as a solar collector site.
    The site has at least one walkable surface with a length and a width direction, the surface being adapted for heat recovery.
    The site has a top layer above a water-retaining substructure.
    Preferably, the top layer is a water-permeable top layer, such that rainwater can seep through the surface in the direction of gravity to the substructure. With a water-tight top layer, water can be fed to the substructure via a gutter device in an edge area. In particular, the top layer has a sports-technical value, which implies a degree of damping when the top layer is walked on.
    The substructure has at least one water-tight lower layer below a laterally water-permeable lower layer for maintaining a volume of water under the top layer. The water-permeable underlayer may be formed by a porous underlayer. The porous underlayer may be formed from poured granulate. The water-permeable underlayer may comprise a layer formed by a plastic mat. The use of an underlayment according to patent NL2019898 under the top layer is advantageous, because this bottom layer provides a top layer with an accurate track-technical value and is also water-permeable in the lateral direction. Moreover, by placing lengths of hose, a water barrier for water conduction in the water-permeable underlayer can be realized in a simple manner. The water-sealed lower layer may be formed by a foil material. Preferably, the water-tight lower layer is provided by a foundation layer. The water-tight lower layer is further preferably formed by a concrete foundation layer, in particular a closed cell concrete foundation layer. The site can hereby be provided with a lightweight foundation layer, while further foundation means can be dispensed with. The substructure within the surface includes a supply channel system including at least one outlet in flow communication with the water-permeable substrate for supplying water to the water-permeable substrate. The substructure within the surface further has a drainage channel system for discharging water from the permeable substratum. The drainage channel system includes an inlet in flow communication with the water-permeable substrate for receiving water from the water-permeable substrate. The feed channel system is arranged separately from the channel system. The at least one outlet is spaced from the at least one inlet. As a result, a water flow can be effected in the lateral direction by expulsion through the water-permeable substrate, the water flow from the outlet of the supply channel system being carried through the water-permeable substrate to the inlet of the discharge channel system. By generating the water flow, heat that has been absorbed by the site can be discharged to a solar collector installation near the site for energy production. The supply channel system and the discharge channel system can be coupled to the solar collector installation that is designed for extracting energy from heated water from the site.
    The solar collector installation can for instance be designed for converting heat into electrical energy or a geothermal installation which is designed for heat storage in a subsurface.
    It should be noted that this concerns the solar collector site.
    A solar collector installation per se is not the subject of the invention.
    Solar collector installations for use in combination with a solar collector are generally known in the art and therefore require no further explanation.
    Compared with a known solar collector site, in which flexible hoses for heat exchange are arranged under the top layer, the solar collector site according to the invention provides an important advantage in the construction of the site.
    The construction of a solar collector site is greatly simplified.
    With the supply channel system, water is supplied at a predetermined position within the surface of the site, whereby water is expelled into the permeable substratum and then collected via an inlet of the drainage channel system.
    By expelling water present in the water-permeable underlayment, hundreds of meters of hose and associated means for securing the hose are unnecessary.
    Due to the simplification of the solar collector site according to the invention, a solar collector sports field for sports associations can be constructed cost-effectively and a sustainable solar collector sports field for more sports associations comes within reach.
    The surface that is arranged for heat recovery may concern the entire site, but in one embodiment the surface area for heat recovery may also concern a part of a total surface of a site.
    For example, 50% of a surface of a solar collector site can be arranged as a surface for heat recovery.
    Due to the principle of expulsion and thereby generating a water flow, the invention provides the advantage that an entire surface of a solar collector site can function as a surface for water extraction without appreciably expensive measures such as a multiplication of the required hose length.
    Preferably, according to the invention, an entire surface of a solar collector site is provided with a surface for heat recovery.
    The solar collector site according to the invention further provides an advantage that a temperature of a site can then be regulated.
    High temperatures can be prevented by dissipating the heat from the terrain.
    As a result, a terrain such as a football field or hockey field can remain more playable.
    Because according to the invention an entire surface of a solar collector sports field can easily be provided with a surface for heat recovery, the sports field can be cooled over the entire surface, so that hot zones on the sports field can be prevented and the entire field can be played on uniformly. Various embodiments of the solar collector site according to the invention are provided. In one embodiment of the solar collector site, a so-called central zone supply is provided. A central zone supply means that the water is supplied to the water-permeable underlayment in a central area of the surface which is adapted for heat recovery. Displacement creates a water current that flows from the central region to a peripheral region of the surface. The water is discharged from the water-permeable underlayer in the edge area of the surface. The supply channel system opens into an inner region of the water-permeable substrate and the drainage channel system has at least one inlet in a peripheral region of the water-permeable substrate such that, in operation, a water flow is generated from the inner region to the peripheral region of the surface. of the site set up for heat recovery.
    The advantage of this embodiment is that this embodiment with a central zone supply means that this embodiment is suitable both for a terrain that is laid out flat and for a terrain with a slope of, for example, approximately 3%. When the terrain has an oblique course in a transverse direction, the water will flow to the edge area under the influence of gravity. The at least one inlet of the exhaust duct system is positioned in height at a lower level than the at least one outlet of the supply duct system. By supplying water in the central region of the surface, a continuous water flow can be maintained.
    In one embodiment of the solar collector site, a so-called series feed is provided. The series supply means that the water is supplied and discharged to the water-permeable underlayment by means of a series of successively linear supply channels and discharge channels arranged alternately. In a serial supply embodiment, viewed in a longitudinal direction of a site, a plurality of supply and discharge channels extending transversely can be arranged one behind the other, whereby a water flow in the longitudinal direction of the site can be generated. In an alternative serial supply embodiment, the plurality of supply and discharge channels may extend longitudinally of the site such that a water flow transverse to the site can be generated. This embodiment with a transverse water flow is advantageous in a terrain with a transverse slope, because the gravity then acts in the same direction as the direction of displacement. This embodiment is advantageously suitable for use in a terrain with a flat location as well as a terrain with a slope in the transverse direction. In an embodiment of the solar collector site having a flat lay, a water flow can be generated from an edge region of the surface for water recovery to an inner region of the surface. To this end, the supply channel system has an outlet in the peripheral region and the discharge channel system has at least one inlet in the inner region of the surface. By pumping water through the supply channel system and discharging it via the discharge channel system, a water flow can be effected from an edge of a site.
    In an embodiment of the solar collector site, in particular with a slope in the width direction, the supply channel system has a supply channel extending in the longitudinal direction of the site. Preferably, the feeder channel extends into a central region of the site when the site has a slope from the central region to an edge region of the site. Preferably, the drainage channel system has a drainage channel extending longitudinally of the site along an outer edge of the site. In one embodiment of the solar collector site, the feed channel is a closed feed channel. The supply channel system may be formed by supply tubes.
    For example, drainage pipes can be used to supply water to the water-permeable sub-layer. In one embodiment of the solar collector site, the feeder channel system has a feeder channel which forms a line supply of water in the water-permeable underlayment. Preferably, the outlet comprises a rectilinear fill chute for forming the line feed. A water flow will be generated by the supply of water, whereby water is expelled transversely with respect to the line supply. In one embodiment of the solar collector site, the line supply of water is formed by a filling gutter. The outlet of the supply channel system comprises the filling chute. The filling trough is open towards the top, such that when water is supplied, the filling trough overflows and water flows into the water-permeable lower layer.
    In one embodiment of the solar collector site, the filling gutter is integrally formed in the water-sealed lower layer. Preferably, the water-tight lower layer is formed by a concrete lower layer. More preferably, the water-tight lower layer is formed by a lower layer of closed cell concrete. With the closed cell concrete as the underlayer, a stable lightweight foundation layer for the terrain, in particular in an embodiment of a sports field, can be provided. When applying the underlayer, the filling channels of the supply channel system can be fitted directly. Slots can be made in the underlayer by placing temporary inserts that are removed after the concrete has cured. The slots can form the gutters. The slots can be milled out after the water-tight sublayer has been poured. By providing the filling gutters integrally in the water-tight underlayer, labor and material can be saved, so that the construction of the site can be realized for a lower budget.
    In one embodiment of the solar collector site, the drainage channel system comprises at least one drainage gutter. Preferably, the drainage gutter is integrally formed in the water-tight substratum, as described above with respect to the filling gutter. Preferably, the discharge gutter extends parallel to a filling gutter of the supply channel system. Preferably, both the at least one filling gutter and the at least one drainage gutter extend parallel to each other. In a series feed, a discharge trough is located between each pair of filling troughs. In operation, a water flow is generated in the water-permeable underlayment between each filling trough and adjacent drainage trough. Preferably, the drainage channels extend at least partially along an outer periphery of the site. With this, an entire surface of the site can be designed as a surface for heat recovery.
    In one embodiment of the solar collector site, the at least one outlet of the feed channel system forms a point feed of water into the water-permeable substratum, later being expelled radially from the point feed. Multiple outlets formed as point feeds may be longitudinally aligned. Preferably, the site has at least one point supply of water in a central region of the site such that water is expelled from the center to the edges of the site. This is advantageous on a terrain with a slope from the center.
    In one embodiment of the solar collector site, the drainage channel system comprises at least one drainage pipe extending into the porous layer.
    In one embodiment of the solar collector site, the water-permeable underlayer comprises at least one water barrier for guiding the water flow. The water barrier can be formed by a localized densification of the water-permeable underlayer, such that the water flow encounters a resistance and as a result seeks another way in the water-permeable underlayer. The water barrier allows the water flow to be controlled in the permeable underlayer. The water barrier may be formed by a barrier item, for example a plate-shaped element, which is incorporated in the water-permeable underlayer. Preferably, the barrier item is placed on the water-tight substrate before the water-permeable substrate is poured. In one embodiment, an underlayer formed by a plastic mat, in particular according to NL2019898B1, can be provided, wherein a piece of hose is arranged in the underlayer, wherein the piece of hose functions as a water barrier. In one embodiment, the water barrier is positioned such that the water flow is controlled in a meandering pattern. The meandering water flow through the permeable underlayer can contribute to greater heat recovery.
    In one embodiment of the solar collector site, the site comprises at least one temperature sensor. Preferably, a plurality of temperature sensors are arranged at regular intervals in the water-permeable underlayer for locally measuring a temperature of the water present. A control unit is provided for controlling the water flow on the basis of a measured water temperature. A water supply can be increased with a rising water temperature and vice versa depending on a situation that arises.
    In one embodiment of the solar collector site, a closed circuit is provided, such that water which has left the porous layer and passed through the solar collector installation is fed back into the porous layer through the supply channel system. In particular, the solar collector installation comprises a water treatment unit for purifying passing water before the water is returned to the solar collector site. It is financially beneficial and sustainable to reuse water.
    The invention further relates to a method for recovering heat from a solar collector site, wherein use is made of a solar collector site according to the invention. The method comprising the steps of supplying water at a first position to a water-permeable bottom layer of the site with a supply channel system and discharging water at a second position remote from the first position from the water-permeable bottom layer of the site with a drainage channel system, such that by expulsion a water flow is generated through the water-permeable underlayer from the first position to the second position. The water flow is generated in that water is simultaneously supplied to the water-permeable underlayer and water is also discharged. In one embodiment of the method, water is supplied in an inner region of a surface for heat recovery and at the same time water is discharged in an edge region of the surface. Preferably, the inner area is a centrally located area of the site and the water is drained off at an outer edge of the site. It should be noted that EP 0 373 282 describes a sports field with a number of corresponding technical characteristics. However, this sports field is not designed to extract solar heat, but to drain and irrigate the sports field. EP0373282 describes a sports field with a water-permeable top layer on a non-deformable support panel, wherein regularly distributed water flow channels are provided below the water-permeable top layer. The sports field is framed by a water flow channel around the sports field. Under the influence of gravity, water can be channeled and drained to the periphery of the sports field. Conversely, it is also possible in the event of drought to return water to the top layer in order to guarantee a desired moisture content of the top layer. A water storage tank and a water pump are provided for supplying water to the sports field if it has been measured by means of moisture sensors that the moisture of the top layer has fallen below a threshold value. Furthermore, the support panel can be provided with heating means with temperature sensors to prevent freezing of the top layer. However, this sports field cannot be used in combination with an installation for recovering heat, because the sports field is not designed for circulating water. Water can only flow back and forth to and from the top layer to maintain a level of humidity. The same applies to the sports field known from EP 3,234,262B1 in the name of Ten Cate Thiolon BV, which describes a sports field framed with a gutter, in which water can flow from this gutter into an underlayer of the sports field and flow back again to prevent it from drying out. US5,944,444 describes an alternative embodiment for draining, irrigating and heating a sports field, wherein a matrix of pipes is incorporated in a porous layer of the sports field for draining and supplying water.
    According to one aspect of the invention, the solar collector site is a sports field. The sports field can be a hockey field, football field, tennis court, athletics track, etc. In particular, the sports field concerns a hockey water field, because the invention is advantageous in particular in that application. In one aspect of the invention, the invention encompasses a solar collector site next to a sports field, wherein the site comprises a road surface, for instance a bicycle path. In particular, the solar collector site is designed as an asphalt solar collector. The invention is advantageous in this application, because the lack of a closed hose circuit for heat exchanger allows a large surface of a road surface to function as a solar collector for heat recovery without the large amount of square meters entailing considerable additional costs.
    The invention will be further explained with reference to the attached drawings. The drawings represent a practical embodiment of the invention, which should not be considered in a limiting sense. Specific detail features can also be seen separately from the exemplary embodiment in a general sense as characterizing the invention, in which: figure 1 shows a schematic view of a surface of a sports field adapted for heat recovery, wherein an outlet of a supply duct system is centrally located within the surface; figure 2 shows a schematic view of a surface, wherein a regular distribution of supply and discharge channels is provided within the surface; figure 3 shows a schematic view of a supply channel system, in which a point supply is provided; figure 4 shows a schematic view in which several supply channels are provided and ensure a distribution of different water flows over the surface; and Figure 5 shows a schematic view of the water barrier for directing a water flow between an outlet and inlet of a supply and drainage channel system. In the figures, identical reference numerals are used to designate corresponding parts. To facilitate an understanding of the description and claims, the words "below, above, vertical, horizontal, longitudinal, transverse, central" have been used with reference to gravity and the coordinate system X, Y, Z, which words are technically functional and not should be interpreted as limiting the scope of protection.
    The figures schematically show different embodiments of a solar collector sports field. The solar collector sports field is an exemplary embodiment of the solar collector field according to the invention. The solar collector sports field consists of a top layer on top of a substructure. The top layer can be designed as a natural grass mat, an artificial grass mat or another type of top layer. This top layer is preferably water-permeable, such that rainwater can be drained directly through the top layer to the substructure. The substructure comprises at least a water-sealed lower layer and a laterally water-permeable lower layer for holding a water volume. The laterally water-permeable underlayer is positioned on top of the water-sealed underlayer. The water-sealed underlayer prevents water from sinking into a subsoil. Preferably, the substructure is two-layer. The water-tight lower layer is preferably formed by a concrete layer.
    Figures 1-3 show embodiments which are suitable for use in a sports field lying flat as well as in a sports field which is situated at a slope of, for example, 0.3%. Figure 4 shows an embodiment with a positioning of a supply and drainage channel system that is only suitable for a sports field lying flat.
    Figure 1 shows a surface A for recovering heat from a solar collector sports field. The sports field has a rectangular design and has a length and a width direction in the X-direction and Y-direction respectively. The surface A can correspond to the entire surface of the sports field, but can also relate to a part of the sports field.
    The surface A comprises a supply channel system S for supplying water and a drainage channel system D for discharging water. The duct systems S, D are in flow communication with a solar collector installation SI. The solar collector installation can for instance be designed as a geothermal installation for the storage of heat in a subsurface.
    The supply channel system S is positioned at a distance from the discharge channel system D. A water flow is indicated by arrows. The flow of water takes place in a water-permeable substratum of the surface from an outlet of the supply channel system S to an inlet of the discharge channel system D.
    In Figure 1, a feeder channel of the feeder channel system S is positioned in a central portion of the surface A. A discharge channel of the drainer channel system D is positioned in an edge region of the surface A. As shown in the left part of Figure 1, the sports field has a slope from the middle area. By placing the supply channel centrally in the sports field and because the supply channel extends in a direction perpendicular to the direction of the slope, a water flow is generated in operation which is directed downwards in the direction of the slope. The arrangement of the supply and discharge duct system S,D as shown in figure 1 is suitable for use in a sports field with a slope as well as a sports field lying flat. Figure 2 shows a variant of the embodiment as shown in Figure 1, wherein a plurality of supply channels S1, S2, S3 and discharge channels are arranged parallel in the surface A. The supply channel system S is symmetrical. As shown in Figure 2, the arrangement is suitable for use in both a sloped sports field and a flat sports field. For a sports field lying flat, it is also possible to position the supply and discharge channels rotated a quarter turn, so that the channels extend transversely under the sports field.
    Figure 3 shows an alternative embodiment of the surface A for heat recovery. The supply channel system S has a plurality of outlets in an inner region of the surface A. The outlets form a point supply of water into the porous layer. As shown, the outlets are positioned centrally in the surface A such that by displacement and optionally an existing slope, a water flow is generated towards an outer periphery of the surface A. The water disperses from each outlet in a radial direction. The drain channel system D is provided around an edge region of the surface A. In the peripheral area, water flows from the permeable underlayment through an inlet in a drainage channel. The water is then discharged to the solar collector installation SI.
    Figure 4 shows a variant of the embodiment of figure 3. The supply channel system has a first and a second supply channel S1, S2. Since the raceway system S has no raceway in a centrally located portion of the surface A, this embodiment is not suitable for a sports field with a slope from a central area. This embodiment is suitable for use in a level sports field. Figure 5 shows in one embodiment a water barrier B of a solar collector sports field. The water barrier B forms a resistance to a water flow and thereby controls a water flow between an outlet of the supply channel system S and an inlet of the discharge channel system D. The water barrier B prevents the water flow from following the shortest path to the inlet. . Due to the presence of a water barrier B the distance water flow bridges can be increased. The water flow can be directed through the porous layer in a meandering pattern.
    The water barrier B may be formed by a local densification in the porous layer.
    Alternatively, the water barrier B may be formed by a barrier item.
    For example, a barrier item may be formed by a plastic sheet recessed into the porous layer.
    A barrier Item may also be formed by a length of tubing received in the laterally water-permeable underlayment.
    The piece of hose can be accommodated in a recess of a plastic mat designed for this purpose, as is known from NL2019898.
