Description

[Technical Field]

[0001] The present invention relates to an assembly (i.e., device) for regulating the temperature of a room (space) in a building, in particular for cooling a room in a building, comprising: - a wall (or building wall) or a ceiling (or building ceiling) forming a supporting element; - at least one calcium silicate plate arranged (at a distance) on a support element (for example a wall or a ceiling), the calcium silicate plate having a back side facing the support element and a front side facing away from the support element and therefore facing the room; - at least one pipe complex that can be circulated by a (liquid) temperature-regulating medium (for example, water) and that is circulated during operation; The present invention relates to an assembly comprising: [Background technology]

[0002] Such a (temperature-regulating) assembly or (temperature-regulating) device cools and alternatively heats rooms in a building and is therefore used as a wall or ceiling heating device and / or a wall or ceiling cooling device. The conduits through which the temperature-regulating medium (e.g., water) flows are, so to speak, hiddenly integrated into the wall or ceiling structure. As the conduit composite, a mat-shaped conduit composite, in particular a (commercially available) capillary mat, is preferably used. In this capillary mat, for example, a plurality of capillaries are aligned and spaced apart from one another, with main conduits positioned opposite each other or on one side of the capillaries as inlet and outlet ports for the temperature-regulating medium. The capillary mat is preferably made of plastic.

[0003] In practice, this type of temperature control assembly is conventionally used, inter alia, for heating rooms, in which case the pipe complex is passed through by a heating medium, for example hot water, and the heat is released into the room via the wall or ceiling structure.

[0004] Alternatively, such a pipe composite or capillary mat can even be used to cool a room by passing a cooling medium, such as cold water, through the capillaries. Problems encountered in practice include, inter alia, the cooling of a room below the dew point and the associated formation of condensation, which leads to dampness in the wall or ceiling structure. This dampness can lead to mold stains and mold growth, even to serious damage to the building. This is particularly problematic in hot and humid regions, where a particularly high demand for room cooling is usually placed on, for example, residential rooms, hospitals, social facilities, or work spaces, to achieve an acceptable or comfortable climate. Currently used temperature control assemblies based on capillary mats function, for example, with gypsum board, or the capillary mat is integrated into a conventional concrete ceiling. To avoid problems caused by condensation during high temperatures and humidity, dew point sensors are used in practice, for example, to monitor the dew point, so that cooling can be stopped when the dew point is reached to avoid endangering the building.

[0005] Against this background, a system has already been proposed and used in which a capillary mat is arranged on a thermally insulating base plate made of a moisture-absorbing material, such as calcium silicate. The surface of the base plate with the capillaries is covered with a layer formed as a clay plaster (see Patent Document 1). Due to its moisture-regulating properties and relatively good thermal conductivity, clay plaster is particularly suitable for the layer covering the surface of the base plate with capillaries. The clay plaster forms a diffusion-open, and therefore vapor-permeable, coating, helping the base plate absorb and release moisture again. The key to this system is the base plate, which also contains moisture-absorbing calcium silicate. Patent Document 1 thus already describes the possibility of cooling below the dew point, so that the resulting condensate is absorbed by the base plate (made of calcium silicate) and the layer covering it (the clay plaster layer) and released again when the cooling device is switched off. While this system has proven effective, there is room for improvement. The present invention therefore relates in particular to refinements and improvements to the system of the applicant described in US Pat. No. 5,649,999.

[0006] Patent Document 2 describes a temperature control element designed as a heating module, which has a thermally insulating base plate made of a rigid foam, wooden, or wood-fiber board. A capillary mat is fixed in place on the surface facing the room, for example with fasteners. The surface of the base plate and the capillary mat are covered with a packing layer made of a thermally conductive material with adhesive properties, and a cover board that is significantly thinner than the support plate is attached to the packing layer. The cover board can be chipboard or fiberboard bonded with cement, lime, or gypsum, or it can be a board made of gypsum.

[0007] Further systems are known, for example, from US Pat. No. 5,629,991 and US Pat. No. 5,629,991, which are usually used primarily for heating purposes.

[0008] For example, Patent Document 5 describes a cooling element with a thermally insulating base plate having capillaries through which a cooling medium flows, the base plate being made of a hygroscopic material.

[0009] Patent document 6 describes the production of a panel heater or panel cooler on the base of a building, which comprises a thermally insulating base plate and capillaries through which a cooling medium can be conducted, the base plate being made of calcium silicate and comprising a clay plaster layer.

[0010] From DE 10 05 04 199 A1 a room element for mounting on a ceiling or wall is known, which is configured as a layer body and has a support shell and a functional layer, the support shell comprising a building board which may consist of calcium silicate.

[0011] Furthermore, from Patent Document 8, an assembly for climate-conditioning a room is known, which comprises prefabricated climate-conditioning boards that can be arranged in a dry structure in layers in the form of a grid under the ceiling, in front of the walls or on the floor. Each climate-conditioning board has a body made of mineral material in the form of a hydrated mixture in different hydration stages, as well as densely textured mineral and / or metal additives incorporating fluid channels made of copper or copper alloys.

[0012] [Patent Document 1] European Patent No. 3146271 [Patent Document 2] German Patent Application Publication No. 4106200 [Patent Document 3] DE 19720863 [Patent Document 4] German Patent Application Publication No. 102004050207 [Patent Document 5] German Patent Application Publication No. 4036520 [Patent Document 6] German Patent Application Publication No. 102012005655 [Patent Document 7] German Utility Model No. 202006000201 [Patent Document 8] DE 19844617 Summary of the Invention [Problem to be solved by the invention]

[0013] Starting from the already known prior art, the problem underlying the present invention is to provide an assembly that allows a room to be thermoregulated particularly efficiently in terms of energy and that allows economical cooling, especially in environments with high temperatures and / or relatively high air humidity, and that preferably is simply and economically constructed and can be assembled simply and economically. [Means for solving the problem]

[0014] To achieve this object, the present invention teaches that in an assembly of the type mentioned at the beginning, the duct composite is configured as a capillary mat and is arranged between the support element and the calcium silicate plate on the rear side of the calcium silicate plate, so that the calcium silicate plate faces the room to be cooled or heated relative to the capillary mat.

[0015] Therefore, an important component of the present invention is a calcium silicate plate, which is a pre-fabricated, shape-stable, and pressure-resistant building board based on silicon dioxide and calcium oxide. According to the present invention, commercially available calcium silicate plates can be used, but instead of being used as a base plate or support plate on the side of the capillary mat facing the wall or ceiling, the calcium silicate plate is placed on the side of the capillary mat facing the room as a cold heat transfer element or alternatively a heat transfer element. During cooling by the system, the cold supplied through the capillary mat is transferred to the calcium silicate plate. The calcium silicate plate receives the cold, stores it within the plate, and releases it from the plate to the room to be cooled (by removing heat from the room). This is particularly important because the calcium silicate plates absorb and store the condensation that occurs in the capillary mat and plates when the dew point is lowered. This allows the plates to not only release the stored cold into the room as "radiative cold" but also as "evaporative cold" into the room to be cooled. The high storage capacity of calcium silicate is particularly advantageous, allowing for a long-lasting, and therefore time-delayed, release of the resulting cold, including radiative cold. This effect causes the cooling effect to persist even when the active cooling device of the capillary mat is switched off. Therefore, this system does not require continuous or continuous active cooling of the medium guided within the capillary mat. Cooling occurs not only when the cold generator (e.g., a heat pump) is switched on, but also when the cold generator is switched off. This allows for a system with significantly lower energy consumption and therefore excellent cooling while being particularly energy-efficient. Absorption of the condensation by the calcium silicate plates is particularly advantageous. The absorbed condensate and thus the cooling energy contained in the temperature control element is released into the room, especially as evaporative cold, when the cooling device is switched off, for example at night.This leads to a similarly even and constant air humidity content in the passively cooled room. Passive cooling creates a consistently comfortable and healthy room climate at night (without the unpleasant drafts that occur in conventional air conditioning systems).

[0016] A particular advantage is that the condensate generated is completely absorbed into the calcium silicate plates, resulting in constant and consistent cooling even in climates where the dew point is frequently or persistently below zero. This not only provides effective and energy-efficient cooling, but also prevents moisture damage and the buildup and accumulation of mold, for example. It also prevents the development of pathogenic bacteria, since cooling occurs without drafts. The calcium silicate plates function both as an active cooling medium and as a storage medium for passive cooling when the system is switched off. This type of cooling achieves a comfortable and healthy room climate without unpleasant drafts.

[0017] The system provides climate protection on the one hand and a healthy and comfortable room climate on the other hand, and is therefore particularly well suited in hospitals or other social or medical facilities.

[0018] The described advantageous properties of the calcium silicate plates are particularly effective in the present invention, since they are not used as support plates for the capillary mat on the wall or ceiling side, but as plates arranged on the room side, which serve to ensure unimpeded energy transfer from the capillary mat to the room. In particular, in the ceiling area of ​​the room, this assembly according to the present invention is advantageous because condensate, i.e., liquid, generated in the capillary mat during cooling is directly and completely absorbed by gravity by the calcium silicate plates arranged below the capillary mat. However, this assembly is also advantageous in the wall area for the reasons mentioned above.

[0019] The (pre-fabricated) calcium silicate plates have a thickness of, for example, 1 cm to 4 cm. Preferably, the thickness is 1 cm to 3 cm. Particularly preferably, the calcium silicate plates have a thickness of 2 cm to 3 cm. Commercially available calcium silicate plates can be used, as they are easy to handle and assemble. They are mineral-based building materials composed of silicon dioxide, calcium oxide, water glass, and cellulose. They are hardened by steam during the process, thereby acquiring special properties for the present invention. Calcium silicate plates do not swell or disappear upon absorbing or releasing moisture. Since their pH value is well above 8.0, there is no risk of mold or pathogens growing or accumulating, even when immersed in water for long periods of time. Furthermore, calcium silicate is highly heat-resistant and meets the fire safety standards of the European Technical Assessment. Calcium silicate is environmentally friendly and can be disposed of without any problems.

[0020] The cooling of the system is carried out via a (liquid) cooling medium that is fed through a capillary mat. The pipe composite is therefore a capillary tube or a capillary mat. These capillary mats can be based on existing or commercially available systems. The capillary mats have a large number of parallel capillaries arranged next to each other, which are manufactured with main tubes arranged opposite each other as inlet or outlet, or in which the main tubes for the inlet and outlet are guided next to each other on one side of the mat. The individual capillary mats (made of plastic) are welded together as required, making it possible to cover large areas, e.g., 13 m², particularly for the cooling process. 2 Areas up to 1000m² are feasible. Capillary mats consist of plastics, such as polyolefins, for example polypropylene, or are based on polypropylene. Polypropylene copolymers, for example polypropylene random copolymer (PP-R), can also be used. Capillary mats have good properties for heat and cold transfer and high strength. Capillary mats can be produced environmentally friendly from recycled materials.

[0021] According to the present invention, capillaries or a capillary mat are always arranged between a support element (wall or ceiling) on ​​the one hand and a calcium silicate plate on the other. The calcium silicate plate is attached to the support element (wall / ceiling) directly or indirectly via the capillary mat, or to a substructure attached to the support element. The present invention can also be implemented in suspended ceilings where a substructure, for example, made of metal, is attached to the ceiling. The calcium silicate plate is then assembled to this (metal) substructure, for example. It is always advantageous to arrange an insulating material, such as an insulating layer or insulating plate, between the capillary mat and the support element (e.g., wall or ceiling). This avoids direct contact between the capillary mat and other (organic) building materials and simultaneously prevents heat loss or heat loss. Optimal and efficient energy transfer from the capillary mat to the calcium silicate plate arranged on the side opposite the insulating material is achieved.

[0022] The system according to the present invention is also distinguished by its simple and economical assembly and installation. Therefore, it is particularly preferable to attach, for example, by screwing, the calcium silicate plate, with the capillary mat interposed, directly or indirectly to a support element, for example, to the support structure of a ceiling or suspended ceiling. For this purpose, the calcium silicate plate can be attached to a wall, ceiling, or corresponding substructure with the capillary mat loosely, i.e., loosely, placed on the plate. Therefore, according to the present invention, the need for fixing the capillary mat to the calcium silicate plate can be omitted. Preferably, the (permanent) attachment of the capillary mat to the wall or ceiling is also omitted. For assembly purposes, a simple pre-fixing of the capillary mat to the ceiling or support structure can be achieved, for example, by first pre-tightening the capillary mat to the ceiling and, if necessary, testing the tightness of the capillaries. The calcium silicate plate can then be assembled, so that the capillary mat can rest on the calcium silicate plate after assembly (during operation) and be supported by this calcium silicate plate without requiring a stable (supportive) positioning of the mat in the ceiling or ceiling structure. Thus, the capillary mat is preferably (completely) resting on the calcium silicate plate by its gravity, ensuring unimpeded heat or cold transfer from the mat to the plate (and from the plate to the mat). Particularly advantageously, the calcium silicate plate does not need to be specially formed or processed for combination with the capillary mat. In particular, in preferred embodiments, grooves or slots for capillaries in the calcium silicate plate, which are frequently used in the prior art, are omitted. This leads to simple and inexpensive manufacturing and assembly.

[0023] Typically, it is expedient to first equip the entire area or a relatively large area of ​​a well or wall with capillary mats, functionally connect the individual mats to each other, and optionally test them for tightness. The entire surface is then glued together with calcium silicate plates. It is advantageous to glue the individual calcium silicate plates with a special calcium silicate adhesive, which covers the joints and thus prevents heat loss or condensate leakage. Furthermore, calcium silicate adhesives can also be used to fill joints and bond to other non-organic structural elements, such as concrete. It is particularly advantageous to cover and glue the entire wall or ceiling without any problems, since calcium silicate plates can be easily and precisely cut and therefore easily and precisely adapted to the geometric shape of the room.

[0024] According to the present invention, it is particularly important that the calcium silicate plate faces the room, with respect to the capillary mat and the overall structure. However, this does not exclude that the surface of the calcium silicate plate facing the room can be provided with another layer. Therefore, after installation in a wall or ceiling, it is advantageous to provide the calcium silicate plate with a (diffusion-open) plaster on the room side or to finish it with a (diffusion-open) plaster layer, for example, a calcium silicate plaster. The plaster layer can have a thickness of, for example, 1 mm to 3 mm. Alternatively or additionally, the calcium silicate plate or plaster layer can be provided with a coating. Particularly preferably, after hardening, a (diffusion-open) paint, for example, a diffusion-open living room paint, is applied to the previously applied plaster layer.

[0025] Overall, the assembly according to the present invention allows for particularly energy-efficient, environmentally friendly, climate-safe, and healthy room temperature regulation, especially cooling. This is particularly true when the temperature regulation of the medium (e.g., water) is performed using a heat pump. The system excels in cooling rooms, especially in regions with prolonged high temperatures and humidity. Furthermore, a particularly positive effect on the room climate is achieved. The system ensures trouble-free and particularly economical room climate regulation in residential and workplaces, public buildings, hospitals, and social facilities. It can replace previously used, environmentally unfriendly, energy-intensive climate control devices in the form of traditional cooling fans or split air conditioners. Furthermore, health-damaging effects in room air, such as dust particles, viruses, and pathogens, in conventional systems can be avoided. Drafts, which are perceived as unpleasant in conventional climate control devices, are also avoided. In conjunction with the use of a heat pump, the possibility arises of switching on the heat pump, e.g., an air-to-water heat pump, only for short intervals or in specific stages, e.g., at a ratio of 1:4, thereby generating significantly less waste heat and thereby contributing significantly less to the heating of the outdoor air. In particular, the waste heat permanently generated by heat pumps in densely populated areas and thus the associated heat storage can be prevented or reduced.

[0026] According to another proposal of the present invention, the room temperature regulation assembly can optionally have a humidifying device for (actively) humidifying the calcium silicate plate, which can or is supplied with a humidifying medium, for example, water, so that the calcium silicate plate can be actively and additionally humidified with water. For this purpose, the humidifying device can include one or more discharge devices, for example, nozzles, spray devices, jet devices or drip devices, arranged, for example, above the calcium silicate plate (and, for example, above the capillary mat), so that the calcium silicate plate can be supplied with water, for example, from above. The humidifying medium reaches the calcium silicate plate, for example, through the capillary mat or between the capillaries.

[0027] Optionally, the humidifying device may have one or more measuring devices, such as one or more humidity sensors, for measuring the moisture content of the calcium silicate plate, which are arranged in or adjacent to the calcium silicate plate. The measuring device can be used to monitor the moisture content of the calcium silicate plate and react to the moisture content, for example, by using the humidifying device to humidify depending on the measured moisture content. Therefore, the humidifying device preferably has a control device for metered release of humidifying medium to the calcium silicate plate, which control device is preferably connected to one or more release devices and / or one or more measuring devices. The control device can control the release of humidifying medium to the calcium silicate plate in time or amount, for example, by releasing a specific amount of humidifying medium at specific time intervals. However, preferably, the control is performed depending on the measured value recorded by the measuring device, thereby particularly preferably controlling or adjusting the release so that a predetermined moisture content is achieved. This allows the possibility of operating the assembly so as to produce a predetermined moisture content, for example, a predetermined saturation of the calcium silicate plates, for example, at least 10%, preferably at least 20%, for example, at least 30%. Within the scope of the present invention, the saturation of the calcium silicate plates is 10% to 50%, for example, 25% to 35%, for example, about 30%. The saturation is the degree of saturation of the calcium silicate plates with a moistening medium, for example, water, relative to the maximum saturation of the calcium silicate plates, which is 100%. At a maximum saturation of 100%, the calcium silicate plates can absorb about 3.5 times their own weight in water.

[0028] Actively adding water to humidify the calcium silicate plates can be advantageous, for example, during the cooling of a room as already described in detail, because the cooling effect described can be increased by the addition of water and thus by the increased moisture content of the calcium silicate plates. The additionally metered water is cooled in the cooled calcium silicate plates and stored therein, so that it is released in the form of radiant and evaporative cold into the room to be cooled, even after the active cooling device has been switched off. This will be explained further below.

[0029] When the temperature control assembly is used and operated to heat a room, it is advantageous or particularly advantageous to supply a humidifying medium and thus actively humidify the calcium silicate plates. The additionally metered water is heated in the heated calcium silicate plates, stored in the calcium silicate plates due to their special hygroscopic properties, and released into the room to be heated in the form of thermal radiation and heat of vaporization. This is particularly advantageous because heating is performed dry, i.e., in some cases, no condensation occurs, unlike during cooling. Therefore, adding water is particularly advantageous in order to be able to utilize the hygroscopic properties of calcium silicate even during heating.

[0030] The capillary mat is passed through by hot water, and the heat generated thereby is released into the water trapped in the calcium silicate plates, which are continuously heated. The heat is stored in the calcium silicate plates and is mostly released into the room to be heated via heat radiation and heat of vaporization. Thus, by preferably continuously supplying the heat in the water to the water trapped in the calcium silicate plates via the capillary mat, heat storage is achieved, and due to the very good thermal conductivity of water, high heat radiation with additional heat of vaporization is achieved as a process.

[0031] Advantageously, the humidified calcium silicate plates heat the room by radiant heat and vaporization during heating, for example, by a heat pump, or cool the room by radiant or vaporization during cooling. When the heating / cooling device is switched off, for example, when the heat pump is switched off, the room continues to be heated or cooled, and the heating or cooling occurs by vaporization or vaporization, which is particularly effective when the heat pump is switched off. The described effect is enhanced by active humidification. Thus, unlike systems known from the prior art, water that may be generated in the calcium silicate plates does not have a negative effect; rather, the system reacts significantly more positively to this water, since the heating and / or cooling effect is enhanced. Thus, water absorbed or actively supplied to the calcium silicate plates supports the function of the system according to the present invention.

[0032] In order to maintain a balance between the heat generation or cold generation with the heat radiation and the heat of vaporization or the cold radiation and the heat of vaporization in relation to the thermal conductivity and water absorption capacity of the calcium silicate plate and the air humidity of the heated room, a predetermined degree of saturation in the calcium silicate plate is preferably adjusted, in which case a degree of water saturation of, for example, 20% to 40%, for example 25% to 35%, for example about 30%, has proven to be particularly advantageous.

[0033] As already mentioned, it is particularly advantageous that the evaporative heat or evaporative cold continues to function for a longer period of time after the thermostat is switched off, and thus after the heat or energy supply is stopped. This allows for greater energy savings compared to conventional heating or cooling methods. This is due to the high heat storage capacity of the water in the calcium silicate plates, which results in continued passive heating (or cooling) of the room as output when the heating (or cooling) device is switched off. At the same time, significant energy savings are achieved compared to conventional devices and methods. Another advantage is the achievement of a comfortable room climate based on constantly adjustable air humidity.

[0034] As already mentioned, a temperature-regulating medium, such as a cooling or heating medium, especially water, flows into the capillary mat via a heat exchanger in the circuit of a heat generator (especially in the form of an air-to-water heat pump) above the calcium silicate plates, thereby regulating the temperature of the calcium silicate plates. Basically, the thermal storage capacity of calcium silicate plates is low in dry, normal conditions, similar to that of, for example, gypsum board. However, advantageously, the thermal storage capacity of water is significantly higher than that of gypsum. Calcium silicate plates also have a relatively low thermal conductivity in dry conditions. However, since the thermal conductivity of water is significantly higher than that of gypsum, moisture in the calcium silicate plates significantly increases the thermal conductivity, especially when additional water is incorporated into the calcium silicate plates. For this reason, the combination of calcium silicate plates with the above-mentioned capillary mat is particularly advantageous, especially during heating (but also during cooling).

[0035] Another important aspect of the present invention is that the radiant heat (or cold) associated with the heat of evaporation (or cooling) continues to function for a long time even after the active temperature control unit (heating or cooling device) is switched off. This allows for significant energy savings compared to conventional heating (or cooling) methods. This is due to the high heat storage capacity of the water in the calcium silicate plates, which results in continued passive heating / cooling of the room when the heating (or cooling) device is switched off. At the same time, significant energy savings are achieved. As already mentioned, another advantage of the present invention is the achievement of a comfortable room climate. Thus, for example, during heating, in addition to the radiant heat of the heated water stored in the calcium silicate plates, the hot water stored in the calcium silicate plates evaporates into the room to be heated. This water increases the air humidity and thus prevents the heated room from drying out. Due to the continuous evaporation and air exchange in the room to be heated, the air humidity in the room remains relatively constant, resulting in a heated and comfortable room climate. The energy lost during evaporation into the surroundings remains contained in the water vapor as latent, or hidden, energy. When the heated air rises in the room, it cools, causing the water vapor to partially condense. During this process, latent, or hidden, energy is released again, thereby heating the surroundings in the form of heat of vaporization. This form of heating is continuous and not time-limited. In this case, the calcium silicate plate acts as a heat reservoir for the medium water and at the same time as a moisture reservoir. The same applies to cooling.

[0036] Due to the high hygroscopic properties of calcium silicate material, calcium silicate plates can absorb 3.5 times their mass of water relative to their own mass.

[0037] The invention relates not only to the described device but also to a method for installing or manufacturing a temperature regulation assembly according to the invention.

[0038] Furthermore, the present invention relates to a method of temperature regulating, for example cooling, a room by means of a temperature regulation assembly according to the present invention.

[0039] The invention will now be explained in more detail on the basis of the drawings, which show only one embodiment. [Brief explanation of the drawings]

[0040] [Figure 1] 1 is a simplified perspective view of a temperature regulation assembly according to the present invention; [Figure 2] 2 is a cross-sectional view of the temperature regulation assembly shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0041] The drawings show an assembly or device that serves to regulate, in particular cool, a room 1 in a building. A room usually has walls and a ceiling 2, which will hereinafter also be referred to as support element 2, since the temperature regulation assembly in the illustrated embodiment is assembled in the area of ​​the room's ceiling. Thus, although the invention is exemplarily shown as a ceiling cooling device, it can equally be realized as a wall cooling device.

[0042] One or more calcium silicate plates 3 are attached (directly or indirectly) to the support element 2, i.e., the ceiling 2. These calcium silicate plates 3 have a rear side R facing the support element 2 and a front side V facing away from the support element 2 and thus toward the room 1. Furthermore, for temperature regulation, e.g., for cooling, a duct system 4 is provided, through which a temperature regulation medium, e.g., water, flows. This duct system 4 is a capillary mat 4. The capillary mat 4 mainly comprises a large number of capillaries 5, which are aligned and spaced apart from one another and which are provided with main pipes 6 for the supply and discharge of water. According to the invention, it is provided that this duct system, i.e., the capillary mat 4, is arranged on the rear side of the calcium silicate plate 3, i.e., between the support element 2 and the calcium silicate plate 3.

[0043] Furthermore, the calcium silicate plate 3 may be provided on its front side V with a (diffusion-open) plaster layer 7 and / or a (diffusion-open) paint layer or coating, which are only indicated in the drawings. Furthermore, an insulating material or insulating layer (also not shown) may be arranged between the capillary mat 4 and the support element 2 (i.e., the ceiling). Basically, it is possible to attach the calcium silicate plate 3 directly to the support element (i.e., the ceiling) via the capillary mat 4 and, if necessary, the insulating material, for example, by means of screws. However, in the embodiment shown in FIG. 1, a substructure 8, for example, a metal substructure for realizing a suspended ceiling, is arranged on the ceiling 2. Therefore, the calcium silicate plate 3 is not directly attached to the ceiling 2, but is attached to the substructure 8, for example, by means of screw fastenings.

[0044] It is particularly important that the calcium silicate plates 3 are not used as a support plate or base board on the side of the capillary mat 4 facing the ceiling 2, but are arranged as cold transfer elements (or alternatively as heat transfer elements) on the side of the capillary mat 4 facing the room 1. The system is preferably used to cool a room, and during cooling, cold supplied via the capillaries is transferred to the calcium silicate plates. The calcium silicate plates receive the cold, store it in the plates, and release it from the plates to the room 1 to be cooled. It is particularly advantageous that, when the dew point is lowered, the calcium silicate plates 3 absorb condensate that occurs in the capillary mat 4 and the plates 3 and store it in the calcium silicate plates 3, which then release the stored cold to the room 1 not only as "radiant cold" but also as evaporative cold. The high storage capacity of calcium silicate, which allows for a long-lasting and therefore staggered release of cold, is particularly advantageous. In particular, the assembly shown in the drawings is advantageous because in the area of ​​the ceiling 2 of the room, condensation occurring in the capillary mat 4 is directly and completely absorbed by the calcium silicate plates 3 arranged under the capillary mat 4 under the action of gravity.

[0045] The calcium silicate plate may be, for example, a commercially available building material plate which may have a thickness D of 2 cm to 3 cm.

[0046] It is also advantageous that no fixed connection between the capillary mat 4 and the calcium silicate plate 3 is required, and that the calcium silicate plate 3 does not have to be specially prepared for the installation of the capillary mat 4. Rather, the calcium silicate plate 3 can be attached to the ceiling 2 or substructure with the mat 4 loosely placed on the plate. However, during installation, it may be expedient to pre-fix the capillary mat 4 to the ceiling 2 or substructure before installing the calcium silicate plate.

[0047] To install the system according to the present invention, it is usually expedient to first roughly pre-fix the capillary mat 4 in the ceiling 2 or substructure (not shown) and test the installed capillary mat for its function and tightness. Then, typically, prefabricated capillary mats are installed in the ceiling area and connected to one another, e.g., welded together. The calcium silicate plate 3 can then be installed, so that the pre-suspended mat rests substantially loosely on the plate 3, i.e., the weight of the mat 4 can be supported by the installed calcium silicate plate 3 even during operation. This has the advantage that heat (or cold) is transferred particularly well from the capillary mat 4 to the calcium silicate plate 3 arranged below it. After installation of the calcium silicate plate 3, the front side V of the calcium silicate plate 3 facing the room is decorated, for example, with a diffusion-opening plaster 7, and the surface is then provided with a diffusion-opening paint.

[0048] The system according to the present invention is particularly suitable for cooling a room 1 by passing a cooling medium, e.g., water, through the capillary mat 4, thereby cooling the calcium silicate plates 3. Cooling below the dew point is particularly advantageous because the condensate generated in the capillary mat 4 is completely absorbed and stored by the calcium silicate plates 3. This allows cooling both when the cooling device, e.g., a heat pump, is switched on and when it is switched off. The calcium silicate plates 3 absorb the condensate generated when the cooling device (or cold generator) is switched on and release the absorbed moisture into the room 1 when the cooling device (or cold generator) is switched off. The calcium silicate plates 3 act, on the one hand, as a cold reservoir for the cooling medium, water, and, on the other hand, as a moisture reservoir for the condensate. Due to the high hygroscopic properties of calcium silicate material, the calcium silicate plate 3 can absorb multiple times its own mass of water in the form of condensate. Overall, energy-efficient cooling of the room 1 is achieved with a comfortable and healthy room climate without the risk of mold formation.

[0049] The system according to the present invention is particularly advantageous when cooling rooms. However, it can also be used to heat rooms without structural modifications, making it possible to achieve both cooling and heating in a single system. The present invention allows for complete carbon (CO₂) neutrality and is therefore particularly climate-protective. A comfortable and healthy room climate can be achieved throughout the year, even in different climate zones with varying temperatures and air humidities, by regulating radiant energy and air humidity. In particular, the problem of condensation formation that occurs in the prior art when the dew point is lowered is successfully addressed. This advantage also arises from passive cooling, taking evaporative cooling into account. Mold formation is prevented by the described overall properties, and in particular by the high pH value of calcium silicate. Furthermore, calcium silicate is advantageously non-flammable and extremely heat-resistant. Furthermore, the system is maintenance-free, can be used in all types of buildings, and significantly reduces energy costs.

[0050] Tests with the described system confirmed the proposed advantages and effects. In particular, it was possible to demonstrate the high storage capacity of the calcium silicate plates for condensation that occurs when the dew point is lowered, as well as the storage capacity of cold captured in the calcium silicate plates even when the cooling device is switched off. Similarly, energy savings were also demonstrated when the device is switched off but continues to cool passively. Measurements showed that the thermal storage capacity and the storage capacity for condensation in the calcium silicate plates are so high and constant that cooling is consistently guaranteed passively, i.e., by evaporation, even when the cooling device is switched off, and that the energy costs for this type of cooling are significantly lower than for conventional cooling methods. Therefore, consistent active cooling by a cold generator is not required with the present invention. Furthermore, it was possible to demonstrate that the air humidity in the room remains constant with the present invention, even when the cooling device is switched off. After the energy is switched off when the outside temperature drops and the resulting evaporation of the room condensate, the passively cooling condensate remains in the calcium silicate plates without losing sufficient storage capacity to absorb new condensate in subsequent sections of active cooling. The relative constancy of the air humidity is also an important aspect, namely, it provides a comfortable and healthy room climate, which is particularly important in hospitals, medical or social facilities.

[0051] Optionally, the temperature regulation assembly according to the present invention may comprise a humidifying device for humidifying the calcium silicate plate with a humidifying medium, for example, water. This option is not explicitly shown in the drawings. The humidifying device may be realized, for example, by providing one or more discharge devices for (metered) discharging a humidifying medium, for example, water, above the calcium silicate plate (and, for example, above the capillary mat) shown in the drawings. Optionally, the humidifying device may have one or more measuring devices for measuring the moisture content of the calcium silicate plate. This may be, for example, humidity sensors arranged in or adjacent to the calcium silicate plate. These humidity sensors are also not shown in the drawings. As already explained, additional humidification by the humidifying device may be advantageous for both heating and cooling. Insofar as a humidifying device is provided, the optionally mentioned insulating layer may be omitted in some cases, or the insulating layer may be arranged above the humidifying device (or behind the humidifying device) so as not to impair the humidification of the calcium silicate plate and not to be humidified itself.

[0052] Overall, the means according to the invention make it possible to realize an assembly or system that is suitable both for heating and for cooling a room (in a combined system) and that has the advantages described, in particular that carbon-neutral or nearly carbon-neutral heating and cooling can be achieved while using a heat pump and renewable energies (for the operation of the heat pump), thus making a significant contribution to climate protection.
