The field of invention is an intelligent noise and temperature insulating construction partition formed by parallel panels glued to a fixed or mobile frame; specifically it proposes glass pane panels fixed to a frame with sealants, to isolate buildings, vehicles and other enclosures from the internal climate and environment such as windows, doors, walls; the partition includes electronic means, its command, control and execution automatically and by the user in real time, and photovoltaic cells that make the partition self-sufficient and intelligent.
Several patents propose construction partitions, windows, and doors, as thermoacoustic insulation solutions and the use of photocells to take advantage of solar energy and means to control its components, as a known solution the following antecedents are mentioned among others:
Patent application CN210714383U “Solar intelligent shutter” proposes a blind with slats positioned over a window, whose slats are photovoltaic cells that generate energy for a motor and controls to rotate the slats, where the mechanism is self-sufficient and can be controlled remotely. This background does not specify a solution with double glass panes as the new patent, which increases energy efficiency, where the new solution has its own sealing mechanism and whose photovoltaic slats are contained between two glass panes and the frame, proposing a new way of solving the insulation problem. Patent application CN104775728A “Double-layer ventilation and thermal-insulation window and energy-saving ventilation and air conditioning system” proposes a system for ventilation of a room taking advantage of the heat generated by a double-glazed window to introduce or extract air from one place to another through pipelines and regulation mechanism. The invention differs from the previous one because the invention does not generate hot air, but instead takes advantage of sunlight to generate electricity, which regulates the temperature of the frame with air circulation in the contact spaces between the glass panes and the frame, without being a heating system.
Windows in the art are passive, with little or no reaction to changes on either side, because it has no means to changing their functions. The invention proposes a thermoacoustic partition to isolate rooms from external or internal environments, refrigeration, and vehicles, which changes its passive action to reaction in real time to external or internal changes in temperature and light through electronic means and communication.
In the art there are efficient thermoacoustic partitions to isolate spaces from noise and temperature that propose intelligent window configurations that are based on changes in opacity in glass pane with films and electricity; but the new invention proposes a less complex and simple solution that is executed with ordinary glass panes, presenting an insulating construction partition with parallel glass pane panels in window frames exposed to atmospheric and Environment changes, to heat and cold on both sides, depending on the season of the year, which is placed in a privileged position to take advantage of solar energy complemented by electronic means, its command, control and execution automatically or by the user in real time, and by photovoltaic cells, to optimize the insulating capacities of the partition.
The invention comprises intelligent thermoacoustic building partitions to harness sunlight and optimize their insulating performance. It proposes a framework made up of profiles made of PVC, aluminum, wood, or any other appropriate material in the art, to which two or more panels are glued into, which may or may not be glass pane, and create an airtight chamber. The profiles that form the frame have internal channels for air circulation and external spaces where thermal and light sensors are located; actuators such as fans, micro pumps, vents are also located; and microprocessors, wires, braces, openings, and vents electrically powered. The planes that create these channels have thermoacoustic bridges built with geometry and material that is softer than the one of the frames. These elements and external spaces are enclosed by a cover-profile on all the external and internal perimeters, fixed to the body of the frame. Photovoltaic cells are located inside the airtight chamber attached to the internal walls of the frame exposed to the sun, which supply electricity to sensors that activate actuators via microprocessor instructions. In this space is also located the blind whose sheets are photovoltaic cells that generate electricity.
The photocells built into the device make it self-sufficient in energy and generate surpluses. It has a microprocessor with instructions for automatic action, modified digitally or by voice, through cell phones and the Internet, so that the components act in real time depending to changes in the environment and at the user's needs.
A window is exposed to atmospheric and Environment elements, to heat and cold on both sides, with the potential to harness solar energy for a profitable investment in various ways.
The insulating construction partition presented in one embodiment of the invention is a useful thermoacoustic window in rooms, buildings, workspaces that require insulating from noise and temperature from the outside or insulating of internal spaces in factories, hotels, meeting places or in mobile rooms.
The intelligent thermoacoustic window of the present invention has two or more glass panes with thermal and acoustic purposes depending to the following configurations:
The thermal function is determined with photocells on the internal perimeter, blind-photocell, fan, microprocessor, control, and algorithm that does not require a micropump. The acoustic function is configured with photocells on the internal perimeter, glass pane supports, fan, microprocessor, control, and algorithm; a vacuum in the airtight chamber that is maintained with a micro pump and does not have a blind.
The invention presents an intelligent thermoacoustic construction partition, preferably a window exposed to atmospheric and Environment elements, to heat and cold on both sides, depending on the season of year, which offers possibilities that solar energy can be used for a profitable investment. Said window is placed in a privileged position to take advantage of solar energy in various forms. Current designs do not incorporate the options offered by current technology.
The invention proposes a thermoacoustic partition to isolate closed rooms from external or internal hot or cold environments, in buildings, houses, workplaces, factories. Also applicable in refrigeration and vehicles. The partition consists of a frame made of PVC, aluminum, wood, or combinations of them, to which two or more insulating panels are glued, and if they are transparent, they are a thermoacoustic window that creates an airtight internal hole. Inside this hole, photovoltaic cells and pressure and light sensors are located on its internal perimeter.
Inside the frame there are independent channels to circulate air, by convection or forced, with electrically operated vents to open or close depending to instructions. In the independent channels are placed fans, micro vacuum pump, microprocessor, motor that drives the blind, wires and reinforcements, powered by electricity generated by photocells.
Within the space between panels and frame there are blinds or folding materials whose surfaces are photocells. The device is self-sufficient in energy and generates surpluses.
It has a microprocessor with instructions so that the indicated components act depending to the environment, which can be automatic, modified digitally or with voice. Environment conditions and user needs can make the device operable with Artificial Intelligence, with appropriate algorithms, not included in this invention.
The external and internal sides of the frame have covers on both sides, which cover the upper and lower external channels, the contact edges of glass panes and frame, and create space where components, controls and wires can be located. These covers have openings that coincide with the ventilation vents of the profile channels.
The profile is designed with the outlined characteristics, and the components to be incorporated are in the market at profitable prices, they are small, reliable and durable; They are part of various applications of daily and continuous use by people and in industries. An example is the cell phone that has pressure sensors, proximity sensors, microphones.
The profile, components and control commands have been incorporated into a system that optimizes the behavior of the partition in accord with climate and noise changes, which can be modified depending to circumstances and needs and create Artificial Intelligence (AI) to adjust automatically. The electricity to operate them is obtained with photovoltaic cells incorporated into the device, it is self-sufficient in energy consumption and can incorporate variables and additional elements. It is an automatic active window or at the user's will, whose instructions can be incorporated and modified before and after installation, with manual or voice controls. Algorithms can make it act with Artificial Intelligence (AI).
Description of Components
The intelligent thermoacoustic construction partition, preferably the intelligent window type, optimizes its performance depending to climatic and Environment changes on both sides to reduce costs, energy consumption and increase user comfort and well-being. Its operation is regulated by instructions to its components based on the information recorded by its sensors, depending to the standard method in these cases:
A. Intelligent thermoacoustic window information detectors composed of the following elements:
a. Temperature sensors, attached to the outer edges of the glass pane. It can be 1 or 2, located in a corner or in the center of the lower and upper glass pane edge. If only 1 place at the bottom, where temperature will be higher than the top edge.
b. Luminance sensor, located in the interior space created by the two panels of glass pane. With its information the blind will be activated.
c. Atmospheric pressure sensor. Located in the airtight chamber formed by panels and frame. It will be installed in windows whose main function is to isolate from noise. With its information the micro pump will be activated.

e. Air inlet and outlet vents. There can be four, minimum two, located one in the lower and upper internal and external parts of the window. Its normal position is “closed”. They open depending to the temperature of the glass pane edges, and the fan starts.
f. Wireless communication. Built in microprocessor.
B. Actuators that are command operators of the smart thermoacoustic window:
1. Fan. Placed inside the profile, in the lower channel, horizontally. It operates when the glass pane edge temperature is equal to the given value, for example 40° C. and it will stop when this temperature is 35° C.
2. Motor of the blind. It raises, lowers the blind and determines the slant of the slats when it is down, as when the blinds are adjusted manually. It can be a step motor or another that allows to act for a set time and stop depending to instructions.
3. Micro pump. Located in the lower channel of the frame profile, it connects to the space created by the frame and the two glass panes, making a seal on this wall by atmospheric pressure from the outside. This seal is part of a duct and valve that allows air to be removed from the space created between the two glass panes. When it creates vacuum, the duct closes. The valve made of flexible material that connects the micro pump to extract air.

D. Instructions to the microprocessor and communication
In the window there are sensors, actuators, microprocessor, and photovoltaic cells, as an autonomous unit. However, if it is a set of similarly positioned windows, it is not necessary for each window to have all the components. In that case there will be a main or base window that contains sensors, actuators, microprocessor and photovoltaic cells, from which instructions for parallel windows, which have conditions similar to the main one. In the parallel ones there will only be actuators and photovoltaic cells, which will be activated with the information from the sensors and instructions from the main one.
The number of parallel windows will depend on the capacity of the microprocessor and may have a specific printed card to fulfill the functions of the intelligent thermoacoustic window.
In a third embodiment, the microprocessor is a component capable of controlling, for example, 20, 50 or more windows with instructions on a board designed to fulfil the functions of an intelligent thermoacoustic window. In all these modalities, the operation and communication use available Internet of Things platforms.
The proposed intelligent thermoacoustic window has several options to function:
The following figures and description illustrate the ideas and features of the invention, which may be expressed and illustrated in various other ways and should therefore be taken as one of the best ways to explain the invention.
The horizontal planes of the profile with which the frame (29) of the window is built and which delimit the upper channel (1) and the lower channel (2) have flexible joints (10) of oval shape incorporated in the profile by coextrusion on its three surfaces. This flexible union has the purpose of damping vibrations and pressures between the panels and reducing thermal and acoustic fluxes.
The lower plane of the profile has seal gaskets (11) that serve as a seal between the thermoacoustic window and the structure where it is installed, it also has fixing means to the structure where it is installed, described in
It has support grid (12) between the glass pane panels so that they do not deform or break due to atmospheric pressure once the air is extracted, in windows with the main function of noise insulation. These supports have coextruded soft materials on their planes for acoustic and thermal damping.
The upper channel (1) is connected to the lower internal channel (2) through a hole (8), which in turn communicates with the internal and external side of the window through openings with lateral vents, a vent air inlet (6) and air outlet grid (7) of air, where the air flows by convection or forced, controlled electrically at will. In the airtight internal chamber (9) there are pressure and light sensors (17), panels with photovoltaic cells (13). In this airtight internal chamber (9) a vacuum is created, when the main function is acoustic insulation, in which case the support grid (12) is placed between the glass pane panels so that they do not deform or break down due to atmospheric pressure.
These support grids (12) have coextrusion for acoustic and thermal damping. In the lower internal channel (2) of the profile that forms the frame, there is a micro vacuum pump and its valve (not shown), microprocessor (27), wires, motors, micro vacuum pump, fan (14), which are communicated with the hole (8) in the horizontal plane of the two channels. Frame reinforcements are in the lower internal channel (2).
In each corner of the external side of the glass pane panes in the internal upper lateral void (18) and the external upper void (18′), which are covered by the internal cover profile (15) and external cover profile (15′), temperature sensors (5) attached to the internal glass pane (3) and to the external glass pane (3′) are located, which send information to control and regulate the action of the fan (14), the inlet grid (6), external outlet grid (7′), internal outlet grid (7) and lowering, raising and unfolding the blind (40), shown in
Wires and controls are in the internal upper lateral void (18) and internal lower void (19) to link sensors and actuators with the microprocessor (27). The external and internal cavities can be more than two on each side if the profile is designed for more than two panels.
Shows flexible joints (10) incorporated in the profile by coextrusion on its three surfaces. This flexible union has the purpose of damping vibrations and pressures between the panels and damping thermal and acoustic flows.
The window has panels with photovoltaic cells (13) placed on the perimeter of the airtight internal chamber (9), between the internal panel (50), external panel (50′) opaque or transparent glass pane, internal pane (3) and external pane (3′), on the side of the frame (29) exposed to the sun, which generate electricity to operate control, sensors, to record instructions and regulate the actuators installed inside the profile, such as fans. The system has instructions and control parameters in a microprocessor (27), which can be modified directly or remotely by the user, by cell phone, depending on the environment and weather conditions by activating the fan, raising, lowering, folding the blind, at certain times, depending on light and temperature conditions. It also has a storage for the electricity generated by the photovoltaic cells, not shown. It has coextruded seal gaskets (11) that serve as a airtight seal between the thermoacoustic panel of frame(29) and the structure where it is installed. It also shows a container with a desiccant (25) located in the upper channel (1) that communicates with the airtight internal chamber (9) through an orifice with a airtight seal and that can be replaced by accessing from the upper internal lateral void (18) by opening (not shown), which is sealed with lid and gaskets.
It also shows an electric resistance (23) through which current generated by photovoltaic cells located on the internal edges of the frame (29) circulates, in the closed space of the airtight internal chamber (9) and by the blind with its unfolded slats. This resistance heats the upper channel (1) and the lower channel (2) that is placed inside the profile, on which a fan will act to distribute the heat in the internal channels of the window and keep the edges of the glass pane at some temperature. larger than the window would be without this resistor; in this case the air intake grid (6) opens. The upper air outlet grid (7) remains closed.
This resistance is applicable in window conditions in a region of seasons, in winter, where the sun is four to five hours a day, with low incidence on the photovoltaic cells. Although the heat generated by the resistance is low, it is important to maintain the structural integrity of the window, since it prevents the glass pane-to-frame adhesives from reaching very low temperatures below zero, in addition to reducing heat loss through window. However, the resistance is not a source of heating, the room will have its own heating. It is a question of increasing the temperature of the glass pane panes and of the insulating glues, which tend to crystallize at low temperatures. For example, raising the edges by 1 to 3° C., instead of −10° C. rising to −7° C. would be enough to preserve adhesives.
Construction partitions and more specifically windows where the panels are glazed, due to their passive nature, are elements built and installed so that they remain in operation for many years without intervention for repairs, except for glass pane breakage and hardware failures. However, the thermoacoustic window of the invention has elements that, when converted from passive to active, may require repairing or updating some of its components, either due to damage, failure, or obsolescence. For example, new electronic, communication, and photocell components may be developed that make it convenient to change them. In the design of the proposed invention, it is possible to access most of the changes only by removing the internal cover-profile (15) to access motors, sensors, wires and connections. Fans and other elements located in the lower channel (2) can also be accessed through openings in their vertical planes, through which they were installed. However, to access the blind (40), to repair and change the photovoltaic cells, it is necessary to access the airtight internal chamber (9), which can be done in at least two ways: a) removing the inner glass pane (3) detaching it from the frame, with a steel rope as vehicle windshields are removed; b) separating the removable internal side of the window that closes the airtight internal chamber (9), with which the components for the required action are accessed. Once complete, place the internal area secured with the contact points around the entire frame. Sealants are placed at these closing points, but bonding should not be used, since would prevent opening the airtight internal chamber (9) on the next event. They can be complemented with small screws on the contact perimeter of the fixed part and the internal removable side. To repair the external panel (5′), the entire window is removed as indicated in
These opening methods do not apply when the window is mainly used for acoustic insulation where the internal airtight chamber (9) is airtight. In this case, the internal glass pane (3) must be removed by detaching it from the frame. Once the task is accomplished, the internal glass pane is glued to the frame and a vacuum is made.
Production of the Intelligent Thermoacoustic Window
The intelligent thermoacoustic window is built in the following stages:
A. Manufacture PVC profiles, by extrusion of the material, the cover-profile (15), the external cover-profile (15′), the support grid (12), the internal panel (50) and the external panel (50′) which can be internal glass pane (3) and external glass pane (3′). The horizontal planes that form the internal channels of the profile are coextruded with a general oval shape as an integral part of the profile, they are not placed afterwards, to dampen noise and interrupt thermal flow. They can be of the same modified softer material. The seal gaskets (11) between the window and the supporting structure are also coextruded.
B. Manufacture air inlet grid (6) and air outlet grid (7), sliders and open-close mechanism, to be inserted in cavities (16).
