Description

Technical Field

[0001] The invention relates to the technical field of dynamic building enclosures, and in particular to a dynamic enclosure structure with window-wall rotation suitable for hot areas and a control method. Background Art

[0002] As an important part of the building envelope, windows undertake important functions such as lighting, view transmission, and ventilation, and are crucial to creating a healthy physical and psychological environment indoors. Window shading and thermal insulation performance are key factors affecting the energy consumption of the building itself. Winter heating and summer air conditioning have become basic equipment for daily work and life. Therefore, it is necessary to improve the overall thermal insulation performance of the building and reduce the heat loss of the building envelope under the temperature difference between indoors and outdoors. Improving the thermal insulation performance of the building itself can increase the cold and heat storage capacity of the building itself, while reducing heat and cold losses, thereby reducing the startup load and operating time of the heating and air-conditioning system, thereby reducing the energy consumption of building operation. It is well known that improving the thermal insulation performance of windows is the key to improving the thermal insulation performance of the building itself.

[0003] Furthermore, the demand for indoor environment of buildings will change with the seasons, building orientation and function, personnel needs, etc. It is hoped that the performance of building envelope structure can be adaptively adjusted according to the above situational changes, making full use of the natural conditions around the building to meet the indoor environment needs, which can effectively reduce the energy consumption of the building and lay the foundation for achieving ultra-low energy consumption and near-zero energy consumption. For example, from the perspective of radiant heat gain: in summer, the solar heat gain of building window openings is the main contribution to building energy consumption, and effective shading is required to reduce the solar heat gain of the building; in winter, it is just the opposite, and building shading must be reduced, and making full use of the solar heat gain of the building is the key measure. Thanks to this, the adjustability of external shading is the first choice for the operation of ultra-low energy consumption buildings in all seasons. From the perspective of heat transfer of envelope structure, it is hoped that the thermal resistance of windows can be reduced during the daytime in winter to increase the solar radiation heat entering the room through the windows, and the thermal resistance of windows can be increased at night to reduce the heat loss of the building; in summer, the thermal resistance of windows can be adjusted according to whether the air conditioner is turned on and the use time of the building during the day and night to achieve the purpose of reducing the heat loss of the building. Therefore, the adjustability of thermal resistance, especially the adjustability of window thermal resistance, is an important means to achieve ultra-low energy consumption buildings, but there are currently no such products.

[0004] One of the implementation schemes closest to the present invention is the sunshade rolling shutter curtain. The overall shading coefficient of the window-sunshade curtain can be adjusted by folding and lowering the sunshade curtain pieces filled with thermal insulation material. At the same time, when the sunshade curtain is fully lowered, it has the potential to increase the thermal resistance of the window. However, due to its structural problems, the overall thermal resistance cannot meet the local ultra-low energy consumption building requirements. At the same time, there is a high risk of air leakage. When using sunshade, it has a very large negative impact on natural lighting and view transmission.

[0005] The other is the detachable window used in traditional buildings. The detachable window achieves the purpose of sunshade, light transmission and view transmission by changing the support angle. However, the current structure cannot meet the requirements of building thermal resistance.

[0006] Existing technologies are mainly in the field of sunshade and window technology, which mainly rely on sunshade facilities to block windows, adjust the solar radiation heat entering the windows according to needs, and rely on glass components to meet different thermal resistance requirements. The two belong to different companies and are installed on the construction site. On the one hand, it increases the uncertainty of the effect. On the other hand, relying on glass components to achieve the insulation effect of a heat transfer coefficient below 2.0W / m2K has a great economic cost. It cannot be popularized at this stage, and it cannot meet the requirements of thermal resistance of ultra-low energy consumption building walls.

[0007] In order to improve the overall thermal resistance of the window, some existing products add a layer of high thermal resistance component to the window system. Although this can achieve the purpose of adjusting thermal resistance and sunshade separately, it increases the thickness of the window system and the difficulty of system construction. It also has high requirements for the wall thickness and insulation layer structure, and has limited applicability. In particular, it cannot meet the thermal resistance requirements of the existing local ultra-low energy consumption building envelope structure.

[0008] There are also some products that combine panels containing phase change materials with windows, and use independent tracks to close and open the panels. They are mainly used in winter. The panels are opened during the day to increase solar radiation heat gain, and closed at night to increase the thermal resistance of the window and panel composite and reduce heat loss. Obviously, this structure cannot meet the summer shading requirements and cannot achieve the purpose of adjusting shading and thermal resistance with seasonal changes. Summary of the invention

[0009] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a window-to-wall conversion device and control method that can dynamically adjust the solar heat gain coefficient and thermal resistance of the window according to changes in the indoor and outdoor environment.

[0010] The purpose of the present invention can be achieved by the following technical solutions:

[0018] Furthermore, the controller of the control system includes a central control unit and a control circuit.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] The present invention provides a dynamic enclosure structure with window-wall rotation suitable for hot areas, comprising a frame system 2, glass window sashes 3, functional parts 4, a mechanical transmission system and a control system.

[0034] The frame of the frame system 2 is made of thermal insulation material, which has good thermal insulation effect, sufficient strength and stability, effectively reduces the energy loss caused by the temperature difference between indoor and outdoor, and ensures the energy saving of the window. The frame system 2 is provided with horizontal card slots on the upper and lower sides, and vertical pipe slots on the left and right sides. Among them, the horizontal card slot is located on the inner side of the frame system 2, and is mainly used to fix the glass window sash 3. Through embedded or sliding installation, the glass window sash 3 is tightly fixed, the air tightness and water tightness are enhanced, and the normal opening and closing operation of the window is allowed at the same time; the vertical pipe slot is located on the side of the frame, which is used to accommodate transmission lines such as wires and data lines, which facilitates the signal and power connection between the control system and sensors, drive motors and other devices, and ensures a simple appearance and hidden lines.

[0035] The glass window sash 3 is made of glass with good light transmittance and heat insulation effect, has good thermal insulation performance, and reduces the transmission of noise generated when the mechanical transmission system moves.

[0036] Functional part 4 is a special insulation board made of high-efficiency insulation material. Its opening degree and angle can be adjusted as needed to achieve energy-saving effect. The insulation board needs to have good sealing and durability to ensure stable performance in different environments. The insulation board is divided into two upper and lower insulation boards, namely the first insulation board and the second insulation board. The upper edge of the first insulation board is movably connected to the upper edge of the frame system 2. As a preferred embodiment, the movably connected is a movable hinge connection; the lower edge of the second insulation board can be controlled and moved by a mechanical transmission system. When insulation is required, the first insulation board and the second insulation board are fully unfolded to form a complete insulation board outside the glass window sash 3 for insulation; when shading is required, the upper edge of the first insulation board remains fixed, and the lower edge of the second insulation board moves upward through the mechanical transmission system, and the first insulation board and the second insulation board are folded. The shading angle can be continuously changed during the movement. When the first insulation board and the second insulation board are fully folded, the shading angle is the largest at this time. There is a movably connected between the first insulation board and the second insulation board. As a preferred embodiment, the movably connected is a hinge connection.

[0037] The mechanical transmission system includes a transmission module, a moving module and a supporting module. The moving module is a guide rail slider assembly, which includes vertical guide rails arranged on both sides of the frame system 2 and movable sliders in the guide rails, and the sliders are fixedly connected to the end edges of the second insulation board;

[0038] The transmission module is a sprocket chain mechanism, including a first sprocket, a second sprocket and a transmission chain, the first sprocket is connected to the frame system 2, the second sprocket is connected to the slider, the transmission chain connects the first sprocket and the second sprocket, the first sprocket, the second sprocket and the transmission chain constitute a movable pulley mechanism, compared with a general movable pulley mechanism, the sprocket chain mechanism has no slipping phenomenon, and it is easier to achieve precise control of the motion position;

[0039] The supporting module is a push rod mechanism 5. As a preferred embodiment, the push rod mechanism 5 is electrically driven. One end of the push rod mechanism 5 is connected to the frame system, and the other end is connected to the side edge of the first insulation board to assist in supporting the functional parts.

[0040] The system uses the guide rail slider assemblies installed on both sides of the frame to cooperate with the drive motor to achieve precise control of the movement of the insulation board. The second insulation board can move up and down along the frame to achieve the function of adjusting the shading angle. The second insulation board is connected to the first insulation board through a hinge, and the first insulation board is connected to the push rod mechanism 5. Through the push rod mechanism 5 and the sprocket, the slider moves at the same time to achieve folding or unfolding. The control system freely adjusts the opening and closing angle of the insulation board according to external light and indoor needs, thereby changing the shading angle and optimizing the lighting and shading effects.

[0041] The control system is installed on the top of the frame or inside the frame, and automatically adjusts the various functions of the window by connecting sensors and drive motors. Sensors are installed inside and outside the frame, including temperature and humidity sensors, light sensors, etc., which are used to monitor environmental changes in real time and feed back data to the central control unit. According to the data, the system automatically controls the selection of insulation state (closing the insulation board) or angle adjustment in the shading state. Data cables and electrical wires are wired through vertical pipe grooves to ensure that the signal transmission between the components is stable and concealed. The vertical pipe grooves are designed with sealing protection devices to prevent the external environment from affecting the service life of the wires. As a preferred embodiment, the mechanical transmission system, the vertical pipe grooves of the frame system 2, and the actuators of the control system are arranged in pairs on both sides of the frame system 2.

[0042] When the external environment changes (for example, the temperature rises or the sunlight intensity increases), the sensor transmits the data to the control system, and the system determines whether shading or heat preservation is needed according to the preset algorithm. The control system adjusts the upper and lower positions of the insulation board or the shading angle by controlling the push rod mechanism 5 and the sprocket chain mechanism to achieve the effect of heat preservation or sunshade. As a preferred embodiment, the control system adopts wireless data transmission technology, combined with the arrangement of wires in the vertical pipe groove, to ensure smooth signal transmission and energy supply during the transmission process.

[0043] The present invention is applicable to buildings in hot areas, which refer to areas with latitudes between 0° and 30° and annual average total solar radiation of 4500 MJ / ㎡ or more. The following are examples of the present invention in different seasons:

[0044] (1) During the summer daytime, the outdoor temperature is high and the sunlight is strong. The main problem facing the building at this time is how to reduce the heat brought by solar radiation, keep the room cool, and reduce the energy consumption of air conditioning. The second insulation board begins to move upward and forms a sunshade with the first insulation board. The second insulation board moves and adjusts the angle to block direct sunlight as much as possible. The sunshade can dynamically adjust the angle according to the angle of the sun, ensuring the sunshade effect while allowing some diffuse light to enter the room, providing natural light and reducing the energy consumption of lighting. In the summer night, the night temperature is relatively low. If the outdoor temperature is lower than the indoor temperature, the main demand of the building at this time is to achieve natural ventilation through windows, reduce the indoor temperature, and reduce the burden of air conditioning at night. At this time, the insulation board remains open, and there is no need to consider the angle of the insulation board. If the outdoor temperature is higher than the indoor temperature, the insulation board will move vertically downward and close completely to maintain the insulation state.

[0045] (2) During the winter daytime, the outdoor temperature is low, but sufficient sunlight can provide natural heating for the room. In this case, the main requirement of the window is to make full use of the sunlight to raise the indoor temperature while preventing the loss of indoor heat. The control system will adjust the folding and opening degree of the insulation board according to the indoor temperature and light conditions. If the sunlight is good, the insulation board can be partially opened to allow sunlight to enter the room, providing an additional heat source for the room and reducing heating energy consumption. During winter nights, the temperature will drop further. At this time, the main requirement of the window is to maintain the warmth of the room and prevent heat from being transferred out of the window. At this time, the upper and lower insulation boards are all closed to form a structure consistent with the wall to maximize the blocking of indoor heat from being lost through the window.

[0046] The following provides embodiments of the present invention under different building types and personnel behaviors:

[0047] (1) Office buildings: Taking summer as an example, during the working daytime, during the morning and afternoon office hours, office workers gather in the office, and environmental comfort and lighting are crucial to work efficiency. The control system detects the outdoor light intensity and indoor temperature through the sensor module 1 installed on the window frame. In order to avoid glare or room temperature rise caused by strong light, the system can automatically adjust the insulation board, and the second insulation board below begins to fold and adjust the angle to block the sunlight. It not only maintains appropriate natural light entry, but also prevents excessive heat from entering the room, thereby reducing air conditioning energy consumption. During the lunch break, when most employees do not need external light, the system adjusts the opening degree of the insulation board, so that the insulation board is completely closed or adjusted to a suitable shading angle to block the light, avoiding direct sunlight affecting the quality of lunch break, while also reducing heat inflow and reducing cooling energy consumption. At night or on weekends when no one is using the office building, the system can completely close the insulation board to ensure the efficient thermal insulation performance of the window and reduce energy loss.

[0048] (2) Residential buildings: Taking summer as an example, during the daytime on weekdays, most of the time, the residence will be unoccupied. The control system can automatically adjust the windows according to environmental changes and personnel needs, so that the insulation board is closed or folded, which not only prevents excessive sunlight from entering the room and causing overheating, but also reduces the energy consumption of indoor air conditioning and maintains a reasonable temperature balance. If the residents are at home, especially in situations such as remote office or resting at home, the system will detect the indoor needs and internal and external environment (including temperature, humidity, light, personnel, etc.) in real time, adjust the angle of the folding insulation board, and maximize the lighting and ventilation to ensure living comfort. On weekdays and weekends, the system detects through the sensor module 1. If the external temperature is low, the degree of opening of the insulation board is reasonably increased (no need to consider the shading angle at night), so as to maximize the indoor and outdoor temperature exchange effect and maintain indoor air circulation. During the daytime on weekends, residents spend more time at home, and the windows can provide lighting or shading functions according to needs. When the sun is strong, the lower second insulation board will move with the slider and adjust the angle to shade the sun, avoiding direct sunlight, but still retaining some natural light.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
