Description

TECHNICAL FIELD

[0001] The present application relates to a south-facing multifunctional outer window for improving the indoor environment of residential and office buildings, in particular, a adjustable multifunctional integrated window integrating ventilation, shading, noise reduction, power generation, thermal insulation enhancement and solar radiation, which is more suitable for use in cold regions. BACKGROUND

[0002] The light-transmitting envelope structure of residential buildings accounts for about one-sixth of the area of the outer envelope structure, and the energy consumption caused by it accounts for 40% of the heating and cooling energy consumption of the building. Therefore, the demand for energy-saving renovation of windows is urgent. However, the existing technology cannot provide a solution to an energy-saving window to reduce energy consumption and meet people's needs in different seasons. Taking the climate conditions in Harbin as an example, there are the following characteristics and needs: 1. The annual power generation in high-latitude regions is considerable, and photovoltaic glass is suitable for installation; 2. The temperature can drop to minus 30 degrees or even lower at night in winter, and there is a high demand for thermal insulation; 3. There is a need for shading during the day in summer; 4. During the day in winter, as much sunlight radiation as possible is needed to take advantage of the only opportunity to passively reduce the heat load in a day; 5. Some buildings near the street are plagued by noise, and local people rely more on outdoor natural wind cooling at night in summer.

[0003] The existing related technology cannot meet the above characteristics and needs.

[0004] 1. The Chinese invention patent with publication number CN116771242A proposes a double-layer photovoltaic glass curtain wall with ventilation function. The outer photovoltaic glass module and the inner glass module are connected with the middle window frame module through the translational sliding support assembly, which can realize opening and closing and adjustment of the inclination angle relative to the middle window frame module. There is a penetrating push rod movable through the middle window frame module, which can drive the outer photovoltaic glass module to move relative to the outer side end of the middle window frame module. The design of the inner and outer push window realizes the heat dissipation of photovoltaic and natural ventilation in the room, but it cannot completely remove the photovoltaic glass when the room needs solar radiation heat, which is not conducive to the application in winter during the day, and the noise reduction problem during ventilation is not considered at all.

[0005] 2. The Chinese utility model patent with publication number CN218759520U proposes a mobile photovoltaic shading structure. According to the low light transmittance characteristic of photovoltaic glass, a plurality of light-transmitting glass and photovoltaic glass of multiple floor heights are arranged in the outdoor side of the window, and the photovoltaic glass or light-transmitting glass is located in front of the window by moving up and down, which solves the demand for radiation heat in winter during the day and shading in summer during the day, but the method of moving the whole up and down with multiple floor heights is slightly cumbersome, which is not conducive to individual control of each household, and the high thermal insulation in winter at night and the ventilation and noise reduction demand in summer at night are ignored.

[0006] 3. The Chinese invention patent with publication number CN 106351556 A proposes a solar heat collecting, shading, energy saving and heat preserving window. The window structure uses a heat preserving roller shutter to move up and down in the left guide rail and the right guide rail arranged in the left frame and the right frame of the window frame, improving the heat preservation performance of the window and achieving the effect of shading. However, it does not actively save energy by making good use of sunlight conditions, and as an energy saving solution, it also ignores the problem of noise. SUMMARY

[0007] To solve the above technical problems, the purpose of the present application is to provide an adjustable multifunctional integrated window, which can be adjusted to cope with seasonal climate differences and noise problems during ventilation, reduce energy consumption and improve comfort.

[0008] The adjustable multifunctional integrated window of the present application comprises: photovoltaic glass, photovoltaic top-hung window, movable window frame, heat preservation roller shutter, high-transmittance glass, high-transmittance glass top-hung window, integrated frame body and connecting rod;

[0009] The photovoltaic top-hung window comprises an upper photovoltaic top-hung window and a lower photovoltaic top-hung window arranged at the upper and lower parts of the photovoltaic glass respectively; the photovoltaic glass and the photovoltaic top-hung window are installed in the movable window frame, and the left and right movable window frames form the outer functional layer; the upper and lower ends of the movable window frame are connected to the upper and lower ends of the integrated frame body through the movable connecting rod, and the movable window frame is moved away from the window side with the movable connecting rod;

[0010] The high-transmittance glass top-hung window is arranged at the lower part of the high-transmittance glass and installed in the inner window frame, forming the inner functional layer; the inner window frame is installed on the inner side of the integrated frame body;

[0011] The heat preservation roller shutter is arranged between the outer functional layer and the inner functional layer, and moves up and down through the guide rail arranged on the side wall of the integrated frame body; the end of the heat preservation roller shutter is provided with a magnetic pull rod, and after the heat preservation roller shutter falls, it is attracted to the magnetic strip in the lower frame of the integrated frame body, dividing the cavity between the outer functional layer and the inner functional layer into an inner cavity and an outer cavity;

[0012] The two sides of the upper photovoltaic top-hung window and the lower photovoltaic top-hung window are connected to the movable window frame through the folding connecting rod and are turned over to the outside with the extension of the folding connecting rod; the two sides of the high-transmittance glass top-hung window are connected to the inner window frame through the folding connecting rod and are turned over to the inside with the extension of the folding connecting rod.

[0013] Further, the adjustable multifunctional integrated window has four working conditions:

[0014] (1) Summer daytime enhanced shading conditions: When the solar radiation is strong on sunny days, turn on the air conditioner indoors to cool down, close the left and right movable window frames of the outer functional layer, close the inner functional layer, and lower the heat-insulating roller blind to separate the cavity between the outer and inner functional layers into an inner cavity and an outer cavity; open the upper photovoltaic top-hung window and the lower photovoltaic top-hung window to reduce the temperature of the outer cavity by ventilation;

[0015] (2) Nighttime ventilation and noise reduction in summer: At night, turn off the air conditioning cooling mode and coordinate with the air conditioning exhaust mode. Raise the heat-insulating roller blind to keep the outer functional layer in place. Open the upper photovoltaic top-hung window of the outer functional layer and the lower high-transparency glass top-hung window of the inner functional layer. Outdoor cold air is introduced into the room through the two top-hung windows to reduce the indoor temperature. Since the outer functional layer and the inner functional layer are in a parallel position, the resonance of the two achieves the effect of noise reduction during ventilation.

[0016] (3) Daytime solar radiation acquisition in winter: When there is sufficient radiation during the day, the outer functional layer with shading properties is moved to the window side, the heat-insulating roller blind is raised, and the inner functional layer is kept closed to form a closed interface to prevent the entry of cold outdoor air and to obtain daytime radiation heat by utilizing the high transmittance characteristics.

[0017] (4) Enhanced insulation conditions at night in winter: The outer functional layer is kept closed, and all the top-hung windows of the outer and inner functional layers are kept closed to form a double-glazed system. The insulation roller blind is lowered, which divides the original single-layer air cavity into two cavities, an outer cavity and an inner cavity, to enhance the insulation effect.

[0018] Furthermore, the inner functional layer includes two high-transparency glass panels on both sides, a high-transparency glass panel in the middle, and two high-transparency glass top-hung windows located below the high-transparency glass panels; the two high-transparency glass panels on both sides are connected to the inner window frame via hinges and can be opened into the room, while the high-transparency glass panel in the middle is fixed to the inner window frame.

[0019] Furthermore, the high-transparency glass and the high-transparency glass top-hung window can transmit high levels of solar radiation across the entire spectrum, and the high-transparency glass is configured as double-layered insulated glass.

[0020] Furthermore, the insulated roller shutter is an aluminum alloy roller shutter with polyurethane insulation.

[0021] Furthermore, the photovoltaic glass is made of amorphous silicon photovoltaic glass or cadmium telluride photovoltaic glass, and a double-glass module with 20% light transmittance is used.

[0022] Furthermore, the outer layer of the integrated frame is a steel frame, which is responsible for bearing the load, and the inner layer of the integrated frame is covered with wood to improve the thermal insulation performance and provide a certain strength. The integrated frame is embedded in the window opening and expansion bolts are installed on the surface in contact with the surrounding walls of the window opening for reinforcement and fixation. If there is a gap between the integrated frame and the window opening, expanding foam will be injected to make it airtight.

[0023] Further, the left and right movable window frames of the outer functional layer are connected by means of a rabbet joint and are reinforced by sealing strips to improve air tightness; if there is a gap between the inner window frame of the inner functional layer and the integrated frame, foaming glue is injected for air tightness treatment.

[0024] Further, the components of the following functional layers can be adjusted manually or electrically:

[0025] The outer functional layer, i.e., the opening and closing and moving position of the left and right movable window frames; the opening and closing and turning angle of the upper photovoltaic top-hung window, the lower photovoltaic top-hung window and the high-transparency glass top-hung window; the opening and closing and falling height of the thermal insulation roller shutter; and the opening and closing and opening angle of the high-transparency glass.

[0026] The adjustable multifunctional integrated window has at least the following beneficial effects:

[0027] 1. Energy saving considering seasonal differences: The adjustable multifunctional integrated window can meet various needs such as strengthening sun-shading during the day in summer, ventilation at night in summer, obtaining solar radiation during the day in winter, and strengthening heat preservation at night in winter, thereby maintaining indoor temperature and reducing energy consumption. The function of photovoltaic power generation can produce energy, which is more cost-effective and environmentally friendly in the long run.

[0028] 2. Ventilation and noise reduction: The adjustable multifunctional integrated window integrates noise reduction design when ventilating in the energy saving scheme, making it more functional, and meeting the needs of noise reduction and energy saving in life, thereby improving the quality of life of users.

[0029] 3. Solving the contradiction between seasonal and day-night application of photovoltaic glass: The adjustable multifunctional integrated window optimizes the opening and closing mode of the photovoltaic glass, solves the balance problem between photovoltaic power generation and solar radiation in winter, and solves the problem of sun-shading in summer and heat preservation at night in winter. The opening mode of the photovoltaic glass moving to the window side is still facing the direction with the longest sunshine duration and the highest radiation intensity, which does not reduce the power generation capacity, avoids the shading of photovoltaic glass to sunlight radiation in winter, and makes it suitable for all seasons, especially in cold regions where the demand for solar radiation is high in winter. The optimized opening and closing mode is helpful for the promotion of photovoltaic glass in cold regions.

[0030] 4. Facilitating secondary development and improving construction efficiency: The present application provides a standardized design mode, which is convenient for subsequent exchange of functional layers or functional components in the existing integrated frame according to different needs or different climate conditions, facilitates secondary development, and greatly reduces the difficulty and time of installing multiple functional layers one by one on site, which is beneficial to improve the engineering quality and reduce the cost.

[0041] In response to the national call for the utilization of renewable energy, and to address the needs of building windows for energy conservation in response to seasonal climate differences, as well as people's comfort and the need for ventilation and noise reduction in daily life, this invention provides an adjustable multi-functional integrated window, such as... Figures la-lc As shown, the adjustable multi-functional integrated window includes: photovoltaic glass 1-2, photovoltaic top-hung window, movable window frame 5, heat-insulating roller blind 2-1, high-transparency glass 3-1, high-transparency glass top-hung window 3-2, integrated frame 6, and connecting rods.

[0042] The photovoltaic top-hung window includes an upper photovoltaic top-hung window 1-1 and a lower photovoltaic top-hung window 1-3 respectively located on the upper and lower parts of the photovoltaic glass. The photovoltaic glass 1-2 and the photovoltaic top-hung window are installed inside a movable window frame 5. The left and right movable window frames 5 form the outer functional layer. The upper and lower ends of the movable window frame 5 are connected to the upper and lower ends of the integrated frame 6 respectively through movable connecting rods 4-1. The movable window frame 5 moves to the window side as the movable connecting rods 4-1 move. Figure 2 This is a diagram showing the closed and open states of a movable window frame.

[0043] The high-transparency glass top-hung window 3-2 is located below the high-transparency glass 3-1 and installed in the inner window frame 3-3, forming the inner functional layer. The inner window frame 3-3 is installed inside the integrated frame 6.

[0044] The heat-insulating roller shutter 2-1 is located between the outer functional layer and the inner functional layer. The heat-insulating roller shutter 2-1 moves up and down via the guide rail 2-2 located on the side wall of the integrated frame 6. The end of the heat-insulating roller shutter 2-1 is provided with a magnetic pull rod of the same width as the heat-insulating roller shutter 2-1. After the heat-insulating roller shutter 2-1 falls, it will be attracted to the magnetic strip in the lower frame of the integrated frame to fix its position, thereby dividing the cavity between the outer functional layer and the inner functional layer into an inner cavity and an outer cavity.

[0045] The upper photovoltaic top-hung window 1-1 and the lower photovoltaic top-hung window 1-3 are connected to the movable window frame 5 on both sides via folding connecting rods 4-2, and flip outwards as the folding connecting rods 4-2 extend. The high-transparency glass top-hung window 3-2 is connected to the inner window frame 3-3 on both sides via folding connecting rods 4-2. Considering space constraints, the high-transparency glass top-hung window 3-2 flips inwards as the folding connecting rods 4-2 extend.

[0046] In specific implementation, such as Figure lc As shown, the inner functional layer includes high-transparency glass on both sides, high-transparency glass in the middle, and two high-transparency glass top-hung windows located below the high-transparency glass. The high-transparency glass on both sides is connected to the inner window frame 3-3 by hinges and can be opened inwards, while the high-transparency glass in the middle is fixed to the inner window frame.

[0047] In specific implementation, both the high-transparency glass and the high-transparency glass top-hung window are composed of materials that are highly transparent to solar radiation across the entire spectrum. In order to obtain solar radiation and have basic thermal insulation performance, the high-transparency glass in this solution is set as double-layer insulated glass.

[0048] In practice, the insulated roller shutter is an aluminum alloy roller shutter with polyurethane insulation, which offers a high cost-performance ratio.

[0049] In specific implementation, the photovoltaic glass can be thin-film photovoltaic glass such as amorphous silicon photovoltaic glass or cadmium telluride photovoltaic glass. Considering its characteristic of being completely movable without blocking light, a double-glass module with a high power generation and 20% light transmittance is adopted.

[0050] In practical implementation, the integrated frame requires high strength and load-bearing capacity, so the outer layer uses a steel frame. Due to thermal bridging issues, the inner layer of the integrated frame is covered with wood with low thermal conductivity and sufficient strength, such as OSB board. The integrated frame is embedded in the window opening. Considering a certain degree of overhang, expansion bolts are installed on the surfaces in contact with the surrounding walls of the window opening for reinforcement. Any gaps between the integrated frame and the window opening are filled with expanding foam for airtightness.

[0051] In practice, the components of the following functional layers can be adjusted manually or electrically:

[0052] The outer functional layer includes the opening, closing, and moving positions of the left and right movable window frames 5; the opening, closing, and flipping angles of the upper photovoltaic top-hung window 1-1, the lower photovoltaic top-hung window 1-3, and the high-transparency glass top-hung window 3-2; the opening, closing, and lowering height of the heat-insulating roller blind 2-1; and the opening, closing, and opening angle of the high-transparency glass 3-1.

[0053] In practice, the joints of the left and right movable window frames 5 of the outer functional layer and the joints of the movable window frame 5 and the integrated frame 6 are all fitted with tongue and groove joints and reinforced with sealing strips to improve airtightness; if there are gaps between the inner window frame and the integrated frame of the inner functional layer, expanding foam will be injected for airtight treatment.

[0054] The technical concept of this invention is as follows:

[0055] (1) Principle of the position of each functional layer: The outer functional layer consists of photovoltaic glass 1-2, photovoltaic top-hung windows 1-1 and 1-3. The power generation of the photovoltaic glass material is inseparable from its light transmittance. The photoelectric conversion of the material requires as much sunlight as possible. However, the low transparency is not conducive to the acquisition of indoor solar radiation during the day in winter. Therefore, the photovoltaic material needs to be on the outside and has the flexibility of control. Moving it to the window side can ensure that its sunlight does not affect its power generation performance, and can also be moved open when it is not needed to avoid interfering with the view or reducing indoor radiative heat gain. The heat-insulating roller blind 2-1 is located between the outer and inner functional layers. Due to its low heat transfer coefficient and the effect of dividing the space to increase the number of air layers, it can play a good heat preservation and heat insulation role in both winter and summer. Moreover, its completely opaque characteristics enable it to enhance the function of sun shading. The inner functional layer consists of high-transparency glass 3-1 and high-transparency glass top-hung window 3-2. The selected high-transparency glass material has the characteristics of high transmittance of solar radiation across the entire spectrum, which is conducive to obtaining solar radiation heat. It also has a basic heat preservation effect and can form a double-layer glass system with the outer functional layer. Through the parallel placement of the two glass panes and the staggered arrangement of the ventilation openings when opened, the resonance of the double-layer glass is relied upon to achieve the effect of noise reduction during ventilation when sound is transmitted.

[0056] (2) Principle of the three top-hung window positions: When the upper photovoltaic top-hung window 1-1 and the lower photovoltaic top-hung window 1-3 of the outer functional layer are opened, natural ventilation can be introduced to reduce the temperature of the photovoltaic glass material, outer cavity, and the outside of the heat-insulating roller shutter, avoiding excessive temperature that would reduce the conversion efficiency of photovoltaic power generation and affect the indoor temperature. The high-transparency glass top-hung window 3-2 of the inner functional layer and the upper photovoltaic top-hung window 1-1 of the outer functional layer open together when the outer and inner functional layers are in a parallel position. While ventilating, the resonance of the two functional layers cancels out some of the sound transmission.

[0057] The adjustable multi-functional integrated window has four operating modes, which are described below along with their working principles:

[0058] (1) Enhanced daytime shading conditions in summer: such as Figure 3a and 3bAs shown, on sunny days with strong solar radiation, air conditioning is often used indoors for cooling, resulting in indoor temperatures lower than outdoor temperatures. Therefore, proper heat insulation and shading are essential. Since the photovoltaic glass 1-2 has low light transmittance, it can act as a shading element in front of the insulated roller blind 2-1, preventing direct sunlight from reaching the blind and raising its temperature. The insulated roller blind 2-1 has a low heat transfer coefficient and is opaque; when lowered, it enhances heat insulation and shading, while the inner functional layer remains closed. The divided inner and outer cavities serve different functions. The inner cavity provides some heat insulation, reducing the impact of outdoor temperature on indoor temperature. The outer cavity, due to photovoltaic work and solar radiation, generates higher temperatures. Based on the principle of thermal pressure ventilation, opening the upper photovoltaic top-hung window 1-1 and the lower photovoltaic top-hung window 1-3 effectively reduces the temperature of the outer cavity, preventing impact on photovoltaic photoelectric conversion efficiency, reducing the temperature difference between the two sides of the insulated roller blind, and decreasing heat transfer.

[0059] (2) Summer nighttime ventilation and noise reduction conditions: such as Figure 4a and 4b As shown, when the air conditioner is turned off in cooling mode at night, the outdoor temperature will be lower than the indoor temperature. In conjunction with the air conditioner's exhaust mode, the indoor temperature will be negative. The insulated roller blind 2-1 will be retracted, keeping the outer functional layer in place. The upper photovoltaic top-hung window 1-1 of the outer functional layer and the lower high-transparency glass top-hung window 3-2 of the inner functional layer will be opened. The cold outdoor air will be introduced into the room through the two top-hung windows and guided to the ground through the lower top-hung window of the inner functional layer. The hot indoor air will be exhausted to the outside by the exhaust system, reducing the indoor temperature. Furthermore, the parallel arrangement of the outer and inner functional layers forms a ventilation channel, and the resonance of the two will reduce noise, achieving a noise reduction effect during ventilation without affecting nighttime rest.

[0060] (3) Operating conditions for receiving solar radiation during the day in winter: such as Figure 5a and 5b As shown, during the day, maximum solar radiation should be obtained to increase indoor temperature and reduce heat load. Considering that compared with conventional double-glazed windows, even with internal circulation, double-layer photovoltaic ventilation windows still increase annual air conditioning power consumption by 33.77 kWh in heating mode alone, it is evident that the outer functional layer containing the photovoltaic glass should be completely removed to avoid the adverse effects of shading on indoor heat load during winter. Therefore, during periods of sufficient daytime radiation, such as 11:00-13:00, the outer functional layer, consisting of the photovoltaic glass and the photovoltaic top-hung window, which provides shading, can be moved to the window side, and the insulated roller blinds can be raised to avoid affecting indoor solar radiation. Only the inner functional layer, which has high transmittance across the entire spectrum of solar radiation, should remain closed, forming a sealed interface to prevent the entry of cold outdoor air and utilize its high transmittance to obtain daytime radiative heat.

[0061] (4) Enhanced insulation conditions at night during winter: such as Figure 6a and 6bAs shown, insulation should be strengthened at night. Therefore, the outer functional layer remains in its original position, that is, the outer functional layer is placed directly in front of the inner functional layer. All the top-hung windows of the outer and inner functional layers are kept closed to prevent cold air from entering, forming a double-glazed system. Since the nighttime temperature in frigid regions can reach -30 degrees Celsius or even lower, it is difficult to meet the high insulation requirements by relying solely on the aforementioned components. At this time, by lowering the low heat transfer coefficient insulation roller blind, the original single-layer air cavity is divided into two air cavities to further enhance the insulation effect.

[0062] This invention addresses seasonal climate variations by adjusting the functional components of an adjustable multifunctional integrated window, reducing energy consumption and improving comfort. It addresses different needs such as solar radiation heat gain during the day in winter, nighttime heat preservation, daytime sun shading in summer, and nighttime noise reduction and ventilation. Furthermore, the integration of ventilation and noise reduction design makes the solution more suitable for the actual urban environment, compensating for the shortcomings of existing energy-saving solutions and better meeting people's increasing pursuit of a higher quality of life. In addition, the standardized integrated frame system constructed by this invention facilitates the replacement of functional layers and components according to different climatic conditions during the design phase. The system is manufactured and assembled directly at the factory, and upon arrival at the site, the frame containing the required functional layers is directly embedded into the window opening and fixed, significantly improving construction efficiency.

[0063] The described solution is only a part of the solution of this invention, not all of the solution. This invention provides a standardized design, and subsequent adjustments to functional layers or functional components can be made based on this invention to meet the climate requirements of different regions and other individual needs. All other solutions obtained by those skilled in the art without inventive effort, including but not limited to: changes in the material, size, quantity, or position of photovoltaic glass, heat-insulating roller blinds, and high-transparency glass; changes in the material, size, quantity, or position of top-hung windows; changes in the opening, closing, or adjustment methods of each functional component; adding or deleting functional components or functional layers based on the existing solution composition; changing the material and shape of the integrated frame; all the above variations or approximate changes are within the protection scope of this invention.
