    [0007]
    [0008] PREVIOUS STATE OF THE TECHNIQUE
    [0009]
    [0010] Heat accumulator modules that use solar radiation to raise the temperature of a fluid contained inside the module are known. Solar radiation allows to take advantage of the sun's energy, converting it into thermal energy accumulated in the accumulator module fluid. This thermal energy is used, among other uses, in the production of hot water for domestic use, whether it is sanitary hot water or heating, or in the production of electrical energy.
    [0011]
    [0012] Sun-oriented walls are known, constructed with materials that can accumulate heat, such as stone, concrete, adobe or water, combined with an air space formed for example with a sheet of glass arranged separately in front of the wall. In this way, solar radiation crosses the glass sheet, reaches the wall, heats it, and the wall emits an infrared radiation that is contained by the glass sheet. Thus, the air chamber between the wall and the glass sheet keeps the wall warm, and in turn the wall allows heating the interior of the construction of which it is part.
    [0013]
    [0014] JP2004256992A describes a heat accumulator module for a building facade closure, comprising a structure embedded in the construction facade, and at least one storage unit with a fluid with thermal inertia inside, the storage unit being arranged inside the structure, said storage unit comprising an at least partially transparent wall that allows the passage of solar radiation, said solar radiation raising the temperature of the storage unit fluid .
    [0015]
    [0016] EXHIBITION OF THE INVENTION
    [0017]
    [0018] The object of the invention is to provide a heat accumulator module for a facade closing of a construction and a modular system comprising said heat accumulator module, as defined in the claims.
    [0019]
    [0020] The heat accumulator module of the invention comprises a structure embedded in a facade of a construction, and at least one storage unit with a fluid with thermal inertia inside, the storage unit being arranged inside the structure, comprising said storage unit a wall that allows the passage of solar radiation, said solar radiation raising the temperature of the fluid in the storage unit.
    [0021]
    [0022] The heat accumulator module comprises at least one exchanger arranged immersed in the storage unit fluid, said exchanger being fluidly communicated with a supply network of a second construction fluid, said second fluid circulating through the exchanger, transferring the fluid from the storage unit the thermal energy accumulated to the second fluid through the exchanger.
    [0023]
    [0024] In this way the passive performance of a facade of a construction is combined, where the internal heat of said construction is retained by the accumulation of thermal energy in the storage unit, with the active improvement of the supply network performance due to the renewable energy supply of the fluid from the storage unit to the second fluid that circulates through the supply network through the exchanger.
    [0025]
    [0026] In this way, and with the application of these heat accumulator modules in the enclosure of building facades, these constructions become hygrothermally efficient, that is, with thermal comfort, being applicable in, for example, constructions of a certain age and lacking an adequate air conditioning system, covering both residential buildings and facilities sports, among others.
    [0027]
    [0028] These and other advantages and features of the invention will become apparent in view of the figures and the detailed description of the invention.

    [0040] DETAILED EXHIBITION OF THE INVENTION
    [0041]
    [0042] The heat accumulator module 100 of the invention is configured to be arranged in the enclosure of the facade 200 of a construction or building 300, as shown in Figures 3 and 4 showing a schematic view of the module 100 embedded in said facade 200 of construction 300, particularly in the part of the facade 200 corresponding to a housing 350. The module 100 of the embodiments shown in Figures 1 and 2, is designed to be embedded in modular systems of self-supporting façade, adapted to the structural enclosure modules of constructions of this type. These enclosure modules 100 are based on a structure 10 or frame, configured to be embedded in the facade 200 of the construction 300, which can be made of wood, for example, constructed with standard profiles, and which allows the arrangement inside it of storage units 20, a heat accumulator module 100 with a storage unit 20 is shown in Figure 1, and a heat accumulator module 100 with four storage units 20 is shown in Figure 2, which together form a wall with a common front face 74. The resistant character of the modules 100 allows, in the case of enclosures to constructions or buildings added to heritage buildings, to maintain the underlying facade without having to adhere to the facade or break it. In the case of new buildings, it considerably reduces the costs of execution because it is already part of the structure of support, thus disappearing any pillar or independent support that, in addition, would occupy space.
    [0043]
    [0044] The storage units 20 can accumulate heat, and are combined, within the heat accumulator module 100, with an air space 73 formed for example with a sheet 70 arranged separately in front of the storage units 20, as will be described later. . The storage units 20 are designed so that they are hollow inside, and have been filled at least partially with a fluid 30 that has thermal inertia. In the embodiments shown of the heat accumulator module 100, the storage units 20 are in the form of a parallelepipedic cuvette, and said cuvette has a wall 21 that is made of glass. In other embodiments of the heat accumulator module 100, for example, destined for cheaper construction, social emergency or international cooperation environments, the glass cuvettes can be replaced with buckets made of plastic, for example, with drums for transport of water, molded in hard-recyclable PVC-type plastics, which would serve as storage units 20.
    [0045]
    [0046] In any of the cases, the facade 200 of the construction 300 where the heat accumulator modules 100 are embedded is interested in being oriented towards the sun in the best possible way. In the embodiments shown, the storage units 20 form as a whole a wall with the common front face 74 that is oriented towards the outside of the facade 200, and a common rear face 75 that is oriented towards the inside of the housing 350 of the construction 300. Therefore, the solar radiation 400 it affects the front face 74, and after passing through the storage units 20 through the rear face 75, it impacts the housing 350. This results in a rise in the temperature of the fluid 30. To achieve greater efficiency in the heating of the fluid 30, and the subsequent use of the accumulated thermal energy, the cuvettes, which have a wall 21 that is permeable to solar radiation 400, having a parallelepipedic shape, have an external part 22, which is the front facing the exterior of the facade 200 in the direction of arrival of the solar radiation 400 to the storage unit 20, which, being made of glass, allows the passage of the solar radiation 400 into the fluid 30. To avoid r that the solar radiation affects the housing 350, and the heat, the storage unit 20 has an internal part 23 that is reflective to the solar radiation 400, obtaining that the solar radiation 400 is reflected in the fluid 30 and the efficiency of thermal energy accumulation improve. That the internal part 23 of the storage unit 20 is reflective can be obtained by smoking the glass or, for example, by applying anti-reflective layers.
    [0047]
    [0048] The heat accumulator module 100 further comprises a heat exchanger 40 arranged submerged in the fluid 30 of each storage unit 20. This exchanger 40 is configured to be fluidly communicated with a supply network 60 of a second fluid 50, forming part of this supply network 60 of construction 300. Thus, the second fluid 50 circulates through the exchanger 40, and the fluid 30, which has accumulated thermal energy due to the heating produced by solar radiation 400, transfers thermal energy to the second fluid 50 through of the exchanger 40. In the embodiments shown of the heat accumulator module 100, the second fluid 50 is water and the supply network 60 is an ACS domestic hot water network that is part of the construction 300, feeding said domestic hot water network ACS for example an electric thermos 500 that supplies hot water to a shower and / or a sink 510. In other embodiments of the m module 100, the grid can be a primary circuit construction 300, such as a heating circuit. And you can also have heat accumulator modules with a plurality of storage units, with a combination where the exchangers of some storage units are Fluidically connect to an ACS domestic hot water network, and those from other storage units fluidly connect to a heating circuit.
    [0049]
    [0050] In the embodiments shown of the heat accumulator module 100, the fluid 30 of the storage unit 20 is a solution that prevents the growth of organisms in said fluid 30, algae for example, and prevents the freezing of said fluid 30 at room temperature. This solution can be formed, for example, with a certain type of alcohol, or in embodiments of modules intended for cheaper construction environments, it can be formed by hydroxides and salts in aqueous medium. In these shown embodiments of the heat accumulator modules 100, the storage units 20 are closed units where the fluid 30 is not replaced. Therefore, said fluid 30 must incorporate the means defined above, so that they do not form Over time microorganisms inside that hinder the transmission of solar radiation 400.
    [0051]
    [0052] The exchanger 40 shown arranged immersed in the fluid 30 occupying a space corresponding to the length of the wall 21 allowing the passage of solar radiation 400 into the fluid 30. In this embodiment, the exchanger 40 is a coil that occupies the entire length of the storage unit 20, with an input and output connected to the supply network 60 arranged at the ends of the unit 20. In other embodiments not shown of the heat accumulator module, the coil may be formed by several rows or columns that occupy the entire space of the storage unit, thus obtaining a better energy efficiency. Of course, the exchanger 40 instead of being a coil can have other configurations such as longitudinal bodies with a multitude of built-in transmission fins.
    [0053]
    [0054] In another embodiment of the heat accumulator module 100, not shown in the figures, the exchanger 40 is formed in the wall 21 of the storage unit 20. In this embodiment the wall 21 forms at least partially a conduit, with an inlet and outlet which is connected to the supply network 60. In this way a large contact surface of the conduit integrated in the wall 21 of the exchanger 40 is also achieved, with the fluid 30 of the storage unit 20.
    [0055] To improve the passive performance of the façade 200 of the construction 300 by means of the arrangement of heat accumulating walls 100, a sheet 70 of solar radiation permeable material 400 is provided, such as glass, said sheet 70 closing the front face 74 of the module 100, said sheet 70 being arranged at a distance of for example four centimeters from the front face 74, defining a space 73 through which the air can circulate, and does not allow turbulence to form. The structure 10 where the storage units 20 are housed has a recess in its front part, so that by arranging the sheet 70 in the outer front part, it creates with the recess where the front face 74 of the storage units 20 is aligned. , the space 73, the sheet 70 leaving an upper opening 71 and a lower opening 72 with the structure 10 of the module 100.
    [0056]
    [0057] These embodiments of the heat accumulator module 100 also comprise an upper grid 80 movable between a passive position and an active position, and which is arranged in the upper part of the structure 10 next to the upper opening 71, running the bottom of said structure 10 between the front face 74 and the rear face 75. And the heat accumulator module 100 also comprises a lower grid 90 movable between a passive position and an active position, arranged in the lower part of the structure 10 next to the lower opening 72, running the bottom of said structure 10 between the front face 74 and the rear face 75. Each of the upper and lower grilles 80 and 90 comprises an internal duct 81 and 91 respectively, with a respective open end 82 and 92 towards the space 73 formed between the front face 74 and the sheet 70, and with the other end 83 and 93 always open towards the inside of the housing 350 in the construction tion 300. The upper grid 80 and lower 90 when they are in the active position, that is to say forward with respect to the front face 74 of the module 100, close the air passage through the space 73, closing the upper opening 71 and lower 72 respectively , abutting one end of said grilles 80 and 90 against the inside of the sheet 70.
    [0058]
    [0059] In an example of passive operation of the heat accumulator module 100, when it is desired to heat the housing 350 of the construction 300 in cold weather, shown in Figure 3, it is about diverting the heated air into the housing 350 behind the sheet 70, in the space 73, for which the upper grid 80 and lower 90 are arranged in the active position, the fluid 30 heated by the solar radiation 400 in the heating units 20 keeps the front face 74 warm, and as the other end 83 and 93 of said grilles 80 and 90 are open towards the housing 350, due to convection, the heated air in the space 73 moves upwards, is introduced into the housing 350 by the other end 83, is cooled leaving heat in the housing 350, said air descends and leaves the housing 350 at the other end 93 of the lower grid 90, starting the cycle again. The heating of the housing 350 can also benefit because the rear face 75 formed by the storage units 20 is also hot and is emitting heat radiation towards the housing 350.
    [0060]
    [0061] In another example of passive operation of the heat accumulator module 100, when it is desired to cool the housing 350 of the construction 300 in warm weather, shown in Figure 4, it is about evacuating the heated air inside the housing 350 . For this, the upper and lower grid 90 are arranged in the passive position, so that the end 81 and 91 of said grilles 80 and 90 are closed, and the air can circulate freely through the space 73 and communicate with the outside of construction 300. The fluid 30 heated by solar radiation 400 in the heating units 20 keeps the front face 74 warm, and as the other end 82 and 92 of said grilles 80 and 90 are open towards the housing 350, due to the convection the hot air in the space 73 moves upwards, and goes outside through the upper opening 71. As the lower opening 72 is also open, the less hot outside air is introduced through said lower opening 72, passes through the space 73 and removes heat from the front face 74 of the heating units 20, leaving convection through the upper opening 71. Thus, in a cyclic manner, it will progressively remove heat from the units of the storage 20, the heat of the housing 350 will be transmitted by conduction to the storage units 20, which will again be removed to the outside of the construction 300. In this way, the temperature of the housing 350 is reduced.
    [0062]
    [0063] In this way, the closing of the facade 200 of the construction 300 is hygrothermally efficient, since in addition to guaranteeing a complete waterproofing against rainwater, it takes advantage of solar radiation 400 to raise the temperature of the fluid 30 contained in the storage units 20. And with the incorporation of the exchangers 40 inside the storage units 20, and their fluidic connection with at least one supply network 60, the active performance of the supply network 60 is improved, since it is possible to raise water supply temperature above of the temperature of the network, thus achieving an energy saving in the production for example of hot water ACS.
    [0064]
    [0065] In the embodiment of the accumulator module 100 shown in Figure 2, said module 100 comprises an actuator A for each upper grid 80 and lower 90, such that, by moving said actuator A, said upper 80 and lower grid 90 can be moved between the passive position and active position, and vice versa. In a manual and cheaper version of the heat accumulator module 100, the actuators A can be handles to be manipulated manually.
    [0066]
    [0067] The heat accumulator module 100 also comprises in this embodiment a temperature indicator T for each storage unit 20, said temperature indicator T measuring the temperature of the fluid 30. The temperature indicator T can be from a thermometer, to a thermostat which allows the user to indicate the temperature to be controlled. The heat accumulator module 100 also comprises for each storage unit an inlet cut-off valve Ve and an outlet cut-off valve Vs of the inlet and outlet conduit respectively of the exchanger 40, which allow to cut the circulation of the second fluid 50 through the exchanger 40. To the extent that more than one independent exchanger 40 is arranged inside the storage units 20, each exchanger 40 will comprise an inlet cut-off valve Ve and an output cut-off valve Vs.
    [0068]
    [0069] This heat accumulator module 100 comprises a control unit, not shown in the Figures, which controls the temperature indicator T, the inlet cut-off valves Ve and output Vs of the exchangers 40, and the actuators A of the upper grid 80 and lower 90, according to a preset control program. It is convenient to effectively manage the performance of the heat accumulator module 100, combining demand and energy production. In the case of having the installation automated, with the control unit, temperature indicators T, actuators A, and cut-off valves Ve and output Vs of the exchangers 40, depending on the hours of the day and the season of the year The control program makes it possible to regulate the opening and closing of the shut-off valves, combining the passive performance of the heat accumulator module 100 to condition the housing 350 of the construction 300, and the active performance of said module 100
