DETAILED DESCRIPTION OF EXAMPLES OF THE EMBODIMENTS ACCORDING TO THE PRESENT DISCLOSURE,
[0051] According to the present disclosure an embodied construction element comprises a water permeable porous material, which allows water passage through the porous material at least in gaseous form, but can provide a capillary transfer of the water in liquid form to soak the porous material throughout to the parts of porous material from the concrete body to the surface from which the evaporation is occurring. According to an embodiment such porous material is sand, especially in an embodiment variant quartz sand. Such sand can comprise a mode of small particles, which small particle mode comprising particles smaller (90% in diameter are smaller) than 100 um in diameter as in size, in the sand, so that the capillary phenomena can provide the water transference in the liquid form from the water delivery piping to the evaporating surfaces of the construction element.
[0052] According to an embodiment the particle size of the material is determined as an average mass basis, considered as a mass of the particle having as a threshold size. According to an embodiment 90% of the particle mass is below the threshold size. According to an embodiment the threshold size is between 400 and 2000 .Math.m. According to an embodiment the threshold size is between 500 and 1000 .Math.m. According to an embodiment variant, the threshold size is between 300 and 700 .Math.m. According to a variant of an embodiment the threshold size is between 200 and 420 .Math.m. According to an embodiment variant the threshold size if between 50 and 280 .Math.m.
[0053] According to an embodiment variant the sand can comprise as incorporated to the sand particle size distribution various ensembles of fine sand particles as modes of particles that have a mode specific mass based threshold size of 90% of mass threshold, between 2 to 50 .Math.m, or below 10 .Math.m, for these modes as such.
[0054] According to an embodiment variant the indicated fine sand particles belonging to these modes are incorporated to the porous material to contribute for capillary forces to distribute the water by capillary mechanisms throughout the porous material embodied as sand.
[0055] According to an embodiment such a porous material is in grains. According to an embodiment variant, a fine dust, having modal size below 25 .Math.m has been added to the porous material as capillary enhancing agent, so to improve the water distribution in the porous material in liquid form.
[0056] According to an embodiment the porous material is provided by sintered material, being obtained sintering an embodied sand, so to provide a porous structure to allow water to penetrate the porous structure in gaseous phase. Such a sintered material can be used as a plate to be added in the manufacturing of the construction element to provide a passage to water for evaporation and passage through such porous material as a material layer, in avoidance compression of the porous materials such as sands, which may compress in presence of rich vibrations, and can leave some parts of the porous material compartment without the porous material if sand being exposed to vibration without re-fill of the voids.
[0057] According to an embodiment variant such sintered porous material plates can be used to hold the sand, at the edges of the construction elements, to hold the sand but preserve the water passage through also at the edge regions.
[0058] According to an embodiment variant the plateaus porous materials and the embodied sands can be used in the same porous material compartment. In an embodiment variant, in layers series in a direction of water vapour flux, i.e. in its gaseous form flux, which is parallel to a direction of a normal of the holding layer forming piece surface. Such plate porous material would be useful, also especially in end wall-forming parts of the construction elements, to provide passage to the water vapour through the porous materials in/from the porous material compartments.
[0059] FIG. 1 illustrates in a schematic way an example of a construction element WE, WE2, WEi, WEj, ΣWE, RE,102 according to an embodiment of the present disclosure having illustrated structure in general, although the product form in shape, in the appearance and dimensions as well as shape can vary according to the intended use. Reference numeral WE as such is denoting to such an embodiment according to which the construction element is in product form of a brick or a like. The product form as a brick could be small brick such as used in bricks in building masonry, or the brick can be rectangular or curved rectangular, as in some chimney masonry. The size can be from few tens of centimetres to a meter, for example. The marking A-A is indicative to provide the cross-section plane, for indication of a view to the reader, as similar also in other product forms with the marking WE2, WEi, WEj, ΣWE, RE, 102 indicative position. Product form as an element, RE and 102 each as such are denoting to roof elements, to provide for example a half or entire roof by the element. According to an embodiment of the present disclosure, the construction element in the named product forms comprise a body CB. The body CB is considered to be such a mechanical part in the structure to provide the main capacity to the mechanical bearing/loading, such as in the wall elements embodied as based to the construction element in its embodied product forms.
[0060] According to an embodiment, the body CB can be made of concrete, which can be reinforced by aluminum, steel and/or iron reinforcement, as well as anticorrosion agent on the reinforcement surfaces, being used as bars and/or nets situated into the body CB in the cast of the body when manufacturing. According to an embodiment the body CB can comprise also a water stop layer, so that the humidity cannot penetrate the body from any side of it. According to a variant of an embodiment, the body can be coated on one side by a material that operates as a molecule sieve, to allow one direction of water to penetrate out of the body, to the porous material in a ready construction element. The coating in such an embodiment forms a second holding layer (106, Sepa) between the porous material and the body CB, as illustrated in FIGS. 7 and 8.
[0061] As illustrated in FIGS. 7 and 8, such a coating in an embodiment variant can form a molecular sieve to provide only one direction passage to the water, even as water vapor, from the body CB, not to the body CB. This alternative embodiment is illustrated the arrow 107 with the diagonal line to indicate the one-way molecular sieve property.
[0062] According to an embodiment the construction element in FIG. 1 example comprises also a porous layer Por, which can be formed in suitable part from sand, which can be embodied by quarts sand. The sand can be composed of several modes of sand particles, according to the sand particle sizes being illustrated by the modes as particular size distributions. According to an embodiment the porous layer can comprise also plate-like porous material forming a solid body, being formed from granular material being sintered together to form a porous structure as plate. Such plate-like porous material can be used at the end walls or edges of the construction element which have an assembly surface facing to other construction elements to form an entity of construction elements ΣWE, such as a wall for example, to be formed from the construction elements WE like wall made of bricks. In such an embodiment, the porous material compartments are to be matched to form a unite porous material volume in the entity of construction elements.
[0063] According to an embodiment the construction element can comprise a holding layer 105 in the example of FIG. 1. The holding layer can be made of holding material, such as copper, aluminum, brass or steel to provide sufficient thermal conduction of the thermal energy from the outer side of the holding layer to the porous material in the porous material compartment in the construction element. According to an embodiment variant, also plastics can be used, within the provision that the thermal conductivity corresponds at least the thermal conductivity of a steel. Although porous material and the compartment for it are marked with the same reference number Por, the context is sufficient to a skilled person to identify the citated object which one is in question.
[0064] According to an embodiment example in FIG. 1, the construction element WE, WE2, Wei, WEj, ΣWE, 102 RE comprises a channel or pipe, Tube, to conduct water in liquid form to the construction element, and especially to the porous material Por in the porous material compartment. The channel or pipe is arranged to provide water to the porous material, the water being distributed by capillary forces acting in the porous material, being assisted a water pump with an appropriate pressure to provide soaking throughout the porous material, so that the evaporating through the perforated holding layer can be started and continued. The position of the piping can be embodied as vertical to have the benefit of the gravity forced delivery to the pipes. Also, horizontal as well as diagonal, i.e. the elevation being between diagonal and horizontal can be used in the water delivery.
[0065] In the evaporation, the evaporating water is taking energy from the construction element side on which the perforation is provided as the passage for the water vapour, which in the evaporation consequently cools the construction element, first at the porous material side, but through energy transfer mechanisms to the concrete body, also the concrete in it and consequently at the free surface of the concrete body at the opposite side of the concrete body CB as the porous material compartment with the porous material Por. The concrete body as well as the porous material can operate also as cooling element capable to take heat energy via their surfaces to the cooled body from a room or space being cooled (cf. item V in FIGS. 7 and 8).
[0066] According to an embodiment the evaporation from the construction element surface through the perforation pores as well as the capillary forces in the porous material provide a pressure difference, which can be used in the water transference in the water providing piping in the null-energy system (cf. FIG. 9). A pump in such an embodied system can be used to provide rapid soaking of the porous material, so that the evaporation can start throughout the porous material side next to the perforated holding element 105.
[0067] According to an embodiment example in FIG. 1 the reference numeral 106 is indicative of a second holding layer 106, Sepa. The reference numeral Sepa is indicative of an embodiment to use the layer as a water vapor stopping layer, to operate as a water-insulation membrane, being positioned between the concrete body CB and the porous material layer Por, to prevent moisture diffusion to the concrete body CB from the porous material. According to an embodiment variant, the second holding layer 106 can comprise a layer that operates as the water vapor stop layer, or as a molecular sieve layer to prevent the water flux from the porous material layer Por to concrete body CB. In FIG. 1 the second holding layer 106 was drawn by dashed line to indicate that the material of the layer can be positioned as embodied to extend throughout the concrete body CB as water stop.
[0068] According to an embodiment any of the construction element example indicated in FIG. 1 can have in an optional embodiment a pipeline Tube to B, to be used in mold or other microbe resistant agent delivery piping. The piping can be positioned into the porous material compartment to cover the porous material so being protected against microbes. The number of such pipes is not limited as indicated by the dashed lines of the reference number.
[0069] According to an embodiment, any microbe resistant agents can be used as such, being deliverable through the pipes in liquid or gaseous form, from the reservoir (B, FIG. 9) to the porous material compartment as such. However, if for example from Boron-derived anti-microbe agents as embodied anti microbe agents were somehow inappropriate to the environment of the embodied system, one feasible option to embody the anti-microbe agent would be the use of lemon and/or vinegar, which are two natural liquids that can prevent mold efficiently. Both, e.g. white vinegar solution and natural lemon are both fresh smelling solutions that can prevent mildew and mold growth. The anti-microbe agent can be added to the system by the pump and/or the valve (C) which can be controlled manually, and/or by a timer for example to provide automation for the adding.
[0070] FIG. 2 illustrates in a schematic way an example of a construction element WE2 as a whole wall element in rectangular geometry of product form. The cross section A-A illustrates that the dashed line indicated plane would provide the same or similar cross section to the embodied wall element as an embodied construction element as indicated in FIG. 1 or as in FIG. 7 or FIG. 8, as elements of an embodied null-energy system forming such an entity as illustrated in the example of FIG. 11. The reference numeral WE as a construction element with product form of a brick is indicative that such a construction element WE2 can be made from the construction elements WE, the dashed line indicative the optionality of the WE2 to be as an entity (also as ΣWE to indicate the character as an assembled product form) of construction elements WE as assembled together. However, the whole element WE2 can be made as a single construction element according to the structure of FIGS. 1, 7 or 8. The formations 202 and 203 are embodied respectively as a window opening 202 and a door opening 203.
[0071] In FIG. 3 example of an embodiment, with the reference numeral ΣWE it is indicated a product form of construction element as an entity, composed of curved product form WE2 and curved product forms WEi and WEj. The curvature radius has been considered constant from the curvature center point, to follow a circular geometry. According to an embodiment variant the radius ri and rj does not need to be the same, although in the FIG. 3 they appear to be at least close.
[0072] However, circular construction element geometry of FIG. 3 give an example of a cone cut line form to be followed by the corresponding product forms of cone cut shape. Further product forms following cone cut form can be embodied with their curvatures of parable, hyperbole, ellipse or a combination thereof to provide an embodied product form for an embodied wall element with wall curvature in horizontal direction, while the vertical direction is straight in the sense embodied in the example of FIG. 5. The cross-section A-A is indicative of similar structure as in FIGS. 1, 7 and/or 8.
[0073] FIG. 4 is illustrative an example of a bunker-embodiment 400. In such an embodiment the entity 400 has been formed by curved structure to compose an arch or cove with the indicated cross section in the embodied construction element WE. According to an embodiment the bunker-embodiment 400 can be embodied as in a form of a cylindrical calot with the mantel to form the integrated outer wall and roof as indicated in the FIG. 4. The ends of the calot can be in plate like geometry by the suitable construction elements embodied with the outer line to match to the curvature of the mantel. The water feed can be separate to the mantel part and to the end part or parts but can be implemented by a common feed with appropriate branching.
[0074] According to an embodiment variant the construction elements WE in the bunker embodiment 400 can have curvature to two directions, so to provide an iglu-form variant as a segment of a sphere or a calotte, as above the ground surface. The marking RE in FIGs is referring to Roof Element as such, also in the integrated roof and wall with the elements to form the entity. According to an embodiment, it is also possible that planar roof elements 102 can be used at the top of such a bunker- 400 or iglu-embodiments 400 of the construction element entity.
[0075] In FIG. 5 illustrates a double curved wall element WE2, 500 as embodied with the indicated cross section A-A (in accordance to FIGS. 1, 7 and/or 8).
[0076] In FIG. 6 is illustrating a roof element RE, 102 with a double curvature 600, as embodied with the indicated cross section A-A (in accordance to FIGS. 1, 7 and/or 8).
[0077] From the examples of FIGS. 5 and 6 a skilled person knows immediately that product form of the construction element WE as a wall element WE2, or as a roof element RE, 102 can be embodied also with curvature according to the designer’s will to provide a customised construction elements WE to form an entity therefrom with desired curvature, to a desired number and curvature radius. A skilled person also knows from the embodiments, that curved construction elements can be manufactured with standardised sizes with the related dimensions and curvatures, being defined in detail specified by the manufacturer.
[0078] Example in FIG. 7 is illustrative of a construction element WE and a roof element 102 at a corner end, in accordance of the WE in FIG. 1, shown as in an example of an embodied entity, which is using the null-energy system according to the present disclosure as embodied. In the example, the corner indicated in the FIG. 7 is illustrative of a corner of such a closure to form a cooled space V, to be cooled by the construction element WE and/or 102 as a system element of an embodied null-energy system comprising an embodied construction element WE and/or 102. Such a volume V can be an interior volume of a building (FIG. 11), or a part thereof. According to an embodiment a wall or a number of walls can be embodied by such a construction element in a building, according to the needs of cooling the parts with the volume V in the building as planned.
[0079] The marking V= V.sub.0(T.sub.0, P.sub.0, RH.sub.0(T.sub.0, P.sub.0(n.sub.0))) is indicative that the conditions in the volume V, in respect to the temperature T.sub.0, pressure P.sub.0 and the relative humidity RH.sub.0 with the composition of substances with water present with an amount of n.sub.0 are mutually dependent. The wide arrow with the water chemical composition reference (H.sub.2O) and with the phase indicating (g) is illustrating a water vapour flux from the room or space V towards to the construction element WE’s surface, into it and through the concrete body CB, in such embodiments in which the water penetration has not been prevented contrary to those in which the water penetration is prevented by a suitable humidity stopping agent in the concrete body CB.
[0080] According to an embodiment of the disclosure, in the FIG. 7 example, there is indicated in the porous material compartment in the porous material Por a water delivery piping, with the respective label H2O(1) and reference numeral Tube. Accordingly, there are three circular dashed line drawn symbols with the reference numeral Tube, indicative of a piping to conduct water into the construction element WE, 102 to the porous material. A skilled person knows immediately from the embodiment, that the number or the direction (cf. FIG. 1 example) of the pipes is not limited only to the number in the shown example but can vary according to the detailed structure and size of the construction element. The dashed appearance of the pipe symbols Tube is indicative that the number as well as position and/or direction of them may vary between different elements as indicated, but also that these pipes can have perforated and/or porous surface to allow passage to the water from the pipes to the porous materials surrounding the pipes Tube, to provide water for the evaporation.
[0081] Although the pipes Tube have been drawn at the middle line of the porous material compartment and the porous material therein, the position can be varied from a construction element to another. According to an embodiment variant the pipes Tube can be mounted near to the surface of the holding layer 105, i.e. in the third part as counted from the holding layer 105 in the thickness direction through the porous material layer of the porous material compartment.
[0082] According to an embodiment variant, the construction element embodied can be manufactured to provide the porous material compartment for the porous material, which as embodied as sand, for example, can be added to the porous material compartment when the construction element as such, or a larger entity in the size is built together from a number of construction elements. The attachment between construction elements WE and/or WE2 can be made by protrusions and recesses as indicated by the reference numeral 103 for such wall-type elements as exemplified by the items WE, WE2 (FIG. 5) as well as similar attachments between such to roof elements RE, 102. The reference numeral 104 is referring to attachment means as protrusions and recesses for roof type elements RE, 102 as construction element WE embodiments, which can be embodied with a lighter structure than wall type elements, although bot embodiments can have similar cross section as indicated in the examples of FIG. 1 and FIG. 7. Both attachment means 103 and 104 can be embodied as pins as protrusions, to be used in correspondingly pin-sized recesses in the elements, with appropriate number and placement of the pins and recesses in the construction element.
[0083] According to an embodiment variant the attachment means can be embodied independently each other, by using tongue-and-groove joints, 103, 104, in suitable part. The internal cross section of the roof element 102 in FIG. 7 has not being drawn to those elements 102 that are in horizontal position with the pins 104 attached, but the roof elements 102 as well as roof elements RE have the basic cross-sectional structure as indicated in the examples via FIG. 1 and FIG. 7.
[0084] When filling the porous material compartment of the entity so formed with the porous material, sand, the pipes Tube can be added to the desired positions for the water feeding Accordingly, the optional piping as indicated by label Tube to B can be added in a same way to the desired position.
[0085] According to an embodiment, with the dashed-line way of drawing, it is indicative that the piping labelled Tube to B has porous surface to provide a passage for a liquid and/or gaseous material into the porous material, but for the presence of the Tube B also optionality. According to an embodiment the piping Tube to B is providing a feed line of an anti-microbe agent from an anti-microbe agent reservoir B (FIG. 9).
[0086] According to an embodiment variant such a piping Tube to B can be used also as an additional source of water for increased evaporation in high temperature conditions. The anti-microbe agent can be delivered by a flow in the pipe, maintained and/or dosed by a pump and a control valve C (FIG. 9) when attached to the null-energy system embodied in accordance of the present disclosure.
[0087] According to an embodiment, the holding layer 105 can be made of porous metal, but can be coated also by a solar cell material to provide the conversion means as solar cells Sc of a solar cell configuration to provide energy contribution for the pumps of the null-energy system and/or entity using the same. According to alternative positions, the solar cells Sc can provide a whole area of the holding layer, with the perforated structure as a custom-made solar cell with the perforation. According to an embodiment the solar cells can be mounted on certain area on to the holding layer 105, for example in alternating way with perforated areas and the solar cell reserved areas.
[0088] Although the position may be vertical for a wall element on such as WE2 for example, the added electricity so produced may be not optimal but sufficient to have contribution being added to the total production, and in low elevation sun shine may contribute to the extended electricity production for the pumps and/or accumulation of the energy into rechargeable batteries, as parts of the solar cell configuration.
[0089] In FIG. 7 as well as in FIG. 8, the wide arrows drawn with dashed lines are indicative of water fluxes in form of water vapour (g). Some of that kind of arrows are drawn to start from the porous material compartment and the porous material therein, when in operation, so indicating that the feed of water in liquid form via the piping Tube, is experiencing a phase transition in the porous material, mainly near the holding layer 105, where the outside coming heat is available to warm up liquid form water and to evaporate in the corresponding temperature, utilising the partial vapour pressure in such conditions in the prevailing temperature, to the form of water vapour to be released through the holding layer 105 perforation pores. According to an embodiment, the water property to have a partial vapour pressure also in all temperatures below the boiling point (100° C. in normal conditions), is used as well as the exponential dependence on the temperature of the water in liquid form, to produce water vapours.
[0090] According to an embodiment variant, there can be also a second holding layer 106, which can be embodied by a molecular sieve to allow one directional passage for the water in gaseous form from the concrete body CB to the porous material Por, but not backwards, the backwards direction being prevented by the molecular sieve of the second holding layer 106. This prevention of backwards flux is illustrated in FIGS. 7 and 8 by the arrow 107 drawn with the diagonal line over the arrow 107 for the embodiment variant in question.
[0091] With reference to the FIGS. 7 and 8, there is also indicated on the roof element 102 triangular water channels (H.sub.2O) having the reclined side comprising a solar cell Sc on such surface. These triangular water channels being used as solar heater channels can be embodied as parts of the roof elements 102 (RE, too) surface, to provide warm or heated water by the circulation through these channels. In addition to taking the heat at their location site of the mount, the channels can also cool the surfaces of the solar cell back sides to improve the conversion efficiency of the solar cells by taking heat from the solar cells to the water circulation of this kind of embodied solar heater.
[0092] The end piece with embodied form of triangle at the corner of the construction elements WE (vertical) and 102 (horizontal or diagonal, cf. FIG. 11 embodiments of such) with the marking Air, is embodied as a channel to be used in equalising the pressure and facilitate concentration gradient equalising, as well as operation as spare route for water to soak the construction element’s porous material Por in the porous material compartment, if such a need were observed. Such a channel can provide water to the corner to provide water to the connected construction elements with perforation/piping thereto.
[0093] According to an embodiment such end piece can be perforated from the sides that are towards the construction elements WE, 102, so to operate also as bridging between the construction elements, but also in suitable part to operate as a pressure equaliser, in situations where the evaporation is about to change from a first state rate to a second state rate, especially if there were extra water being left and pumped before the system would adapt to the changed conditions and equilibrium therein for the operation.
[0094] With reference to the FIG. 8, the example is indicative of a similar corner implementation as indicated in FIG. 7 by the embodied construction element implementation, which additionally in FIG. 8, for an optional embodiment to add, further comprises a lip system 101 to shadow the wall for equalising the surface temperature of the evaporative surface of the holding layer 105. However, such lips 101 can be used as extra area to mount solar cells Sc in reclined position, towards the maximum solar radiation, so to improve the electricity production compared to the mere vertically positioned solar cells. The triangular shape is an example to provide the lips, with support to the holding layer 105, but can be embodied without such, but having correspondingly stronger structure for the lips 101.
[0095] In FIG. 8 the embodied lip formations 101 can have also a chute or channel arranged for dropping water droplets, which may form onto the surfaces of the lips 101 at the shadow side of them, while evaporation is going on through the pores of the holding layer 105 and the water condenses onto the back side. The chutes can be arranged to collect the so obtained water to be pumped back to the used from the water reservoir.
[0096] With reference to the embodiments apparent from the FIG. 9, which is embodying a null-energy system 900 using an embodied construction element WE, WE2, RE, 102, WEi, WEj or a composition of selected product forms of such ΣWE.
[0097] According to an embodiment, such system 900 comprises an ensemble of construction elements according to the applicable selection to form an entity thereof as indicated in the FIGS. 1 to 8, with the optional implementations in applicable part selected for the presence. Such a system 900 can comprise filters F to filtrate the water F as well as to filtrate F0 anti-microbe agent feeds, to remove impurities from the flow, so to keep the pores of the porous materials in the porous material compartment in operational conditions to pass water to the holding layer by the capillary forces and through the pores as evaporated, to minimise the risk of clogging the porous material and the capillaries inside such According to an embodiment the filters are also protecting the pumps (Pump) as well as the pipes to get dirty. According to an embodiment filter F0 can be embodied as attached to the construction element WE.
[0098] According to an embodiment the water flow can be adjusted by the pump, in control of a thermostat Th(V) being mounted into the volume, whose cooling is intended to be controlled. The capital C with the arrow is indicative of a valve to be used in controlling the flow through the corresponding pipes at the dedicated position of the system structure pipes, which are drawn by double line to illustrate pipes. Small arrows are illustrating the flow or flux direction.
[0099] The anti-microbe agent line with the pump and the related control valve C has been drawn by dashed line to indicate optional embodiment with these parts. Similar optionality is indicated also for the lips 101 as well as the chute system to collect, filter and pump the collected water back to the reservoir.
[0100] The pumps are drawn close to the apparent reservoirs of water and anti-microbe agent, but in an alternative embodiment they can be situated further away to be so included in a diversified manner via feed line pipes to the null-energy system.
[0101] According to one embodiment variant, tab water can be used in suitable part, where applicable.
[0102] The solar panels Sc in the system 900 can be embodied on the surfaces as indicated in the FIGS. 1, 7 and 8 embodiments. The solar panel Sc near the marking Sun at left in FIG. 9 has been indicated to provide electric power by the label kWh, to indicate electricity production for the system parts, especially the pumps. The solar panel Sc can have at the panel the necessary solar panel configuration to provide the electricity to the pumps. Such configuration can comprise also accumulators to provide electricity stored to the moments of no Sunshine available, but the pumps to be used. At the upright corner the solar panel Sc can be diversified to the roof for example, on to the solar heater pipe surfaces as illustrated in FIGS. 7, 8, 9, and 11, with the insert in FIG. 11. Hot water pump in the system can be used to circulate water through the solar heater pipes, to take heat and so cool the solar heater surfaces, also the solar cells on such surfaces, and circulate the water to a hot water delivery reservoir, which can be in an alternative embodiment connected to the water reservoir of the cooling line of water to be pumped to the porous material. The water flow can be controlled by a controller valve C. The symbols e.sup.- with the apparent arrows are used to illustrate electrical power transference, without taking position to the electron movement direction as such.
[0103] Water vapour flux from the construction element WE surface is schematically indicated in FIG. 9 by an ensemble of six arrows below the marking H.sub.2O(g) as directed away from the porous material Por in the porous material compartment of the construction element WE.
[0104] FIG. 10 is illustrative of sand particle size (DP) distributions of the porous material as embodied by sand as such, illustrated by a composition 1000 of sand particle size distribution as modes for the sand particles. In FIG. 10 the particle size has been shown on logarithmic axis as used to be in connections of particle size distributions. The particle mass at given size has been indicated on the vertical axis, to follow a log-normal size distribution notation. The vertical bar at the right side of the Mode 2 is indicative an example in which the sand particle follow a size distribution of a composition of the modes Mode 1 and Mode 2 as the main modes of the sand particle size distributions. The 90% threshold has been marked, and accordingly in the shown example 90% of the sand particles are smaller in mass than that at the threshold size.
[0105] In FIG. 10 there are indicated as examples of arbitrary illustrative modes, Mode 1, Mode 2, to exemplify as such that the sand as the porous material can be particular dedicated sand as a mixture of sands that have different sized sand particles, the mixture being composed of an ensemble of particles in the modes, so to have the capillary forces based suction as a consequence of the evaporation being optimised.
[0106] According to an embodiment such a particle size distribution represent a mode of the porous material, which can be a composition of several embodied modes, each mode with a specific weight in the so formed multimodal porous material size distribution. According to an embodiment variant, the modal width and symmetry of fine sand particles mass size distribution whose particles size can follow so called self-preserving distribution in the shape, especially the width, which is considered as a shape parameter rather than having connection to the aggregation.
[0107] With reference to the FIG. 11, an entity 1100 is made of embodied null-energy system 900 comprising several product forms of construction elements WE, as put together to form a building, whose interior (see V in FIGS. 7 and 8, for example) can be cooled according to an embodiment of the system 900. The entity 1100 in the example comprises an entity consisting of a wall single element WE2 (FIG. 2, FIG. 5) at least at one side which is an outer wall. At the head end the building has a similar wall element WE2 but made into triangular form for the mount position geometry to fit to the roof formation. The entity 1100 has also a wall element, which is implemented by using product form of brick-like embodiment WE as in composition entity ΣWE below said head end. In the example the roof element 102 has been used, with a number of triangular solar heater tubes with solar cells thereon, on the reclined surface towards the Sun. Although the shown shape of the building in FIG. 11 is given as an example, other forms of walls as embodied in FIG. 5 by the exemplified curvature and/or alternatives of flat roofs as embodied in FIG. 6 for example can be used to compose alternative entities to an entity 1100 as a building to be cooled by an embodied null-energy system 900 being embodied by the composition of different kind of construction elements WE, WE2, WE, WEj, ΣWE, 102, RE.
[0108] An accordingly embodied building 1100 can have also as an alternative power source a wind turbine WT (cf. FIG. 12), which is illustrated by the ellipse on the WE2 element as a flow entrance or exit for the wind turbine, in the example being hidden to the roof structures, because of scenery-related reasons or rules for the buildings etc. to be locally obeyed.
[0109] In FIG. 12 there is schematically indicated a null-energy system 1200 according to an embodiment of the present disclosure. The system 1200 is based on the system 900 as can be embodied basically as in FIG. 9 illustrated with the alternative embodiment variants as such. The embodied system can be such a building as embodied in FIG. 11 related examples, or a part of such a building 1100, i.e. a wall or roof part which is positioned towards a desired point of a compass. In such embodiment alternatives that have solar cells on the construction elements on their surfaces in the system 900, the direction can be towards the sunlight maximum to provide maximum amount of solar power.
[0110] However, in the alternative embodiment example 1200 in FIG. 12 there is embodied an alternative power source wind turbine WT, to be used alternatively or in supplement to the solar cells Sc. The way of drawing is indicative that the null-energy system 1200 as embodied can additionally have several wind turbines within the system 900. According to an embodiment variant, the wind turbines WT, which are arranged to generate electricity from air flows near and/or through the system 1200, for example a building or a part thereof, can be embodied as hidden type being mount into tubular forms that hide wind turbines into the structures of the building 1100, but leave passage to the wind to the turbine to be rotated and the consequential electricity being produced for the system needs, such as the operation of the pumps and battery re-charges, for example.
[0111] According to the way of drawing, the number of wind turbines is not limited in the system 1200. One of the wind turbines WT has been drawn partially out of the system 900 illustrative lines, which might be the case for an implementation to an embodied building with air conditioning pipes extending outwards from the building, or, can be positioned on roof in a hidden position not to be visible from the ground, because of a wall between line of sight and the wind turbine on a penthouse patio, for example.
[0112] Consequently, a skilled person may on the basis of this disclosure and general knowledge apply the provided teachings in order to implement the scope of the present invention as defined by the appended claims in each particular use case with necessary modifications, deletions, and additions.
