Description

Technical Field

[0001] The present invention relates to the technical field of building exterior windows, and in particular, to a green plant-assisted ventilation energy-saving window system based on photothermal sensing and intelligent control and its control method. Background Art

[0002] Building shading devices are of great significance for improving the natural lighting efficiency of buildings, reducing building energy consumption, and enhancing the indoor photothermal comfort. Among them, due to the influence of the natural movement law of the sun rising in the east and setting in the west, the probability of glare on the east and west facades of buildings is higher than that on the north and south facades of buildings. The west sun exposure problem is serious, and the photothermal comfort is poor, which has an adverse impact on the work efficiency and visual health of residents. At the same time, due to the need to frequently open and close curtains and supplement artificial light sources to avoid glare, the building energy consumption is further increased, bringing great inconvenience to residents who use the east-west facing window space for work and study.

[0003] In the current existing technologies, building external shading mainly relies on movable horizontal louvers to achieve. The core of this technology lies in precisely controlling the angle adjustment of the louvers to achieve the optimal shading effect at different times. However, for the west facade of buildings with extremely high light intensity in summer, relying solely on setting louvers for shading often fails to effectively alleviate the problem of rising indoor temperature caused by direct sunlight on the west side. At the same time, strong light will also cause glare phenomena, which have an adverse impact on the home life and home office experience. In addition, in the existing technologies, attempts are made to guide the indoor hot air circulation by increasing exhaust devices. Although the indoor environment is improved to a certain extent, it inevitably brings additional energy consumption problems. It is mentioned in the existing papers that the green skin unit has a strong weakening effect on temperature, but the blocking effect on solar radiation is poor. How to use the green skin unit to achieve cooling while realizing energy-saving ventilation and overcoming the glare problem has become the main design goal of the composite function exterior window. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] The present invention provides a green plant-assisted ventilation energy-saving window system based on photothermal sensing and intelligent control and its control method, aiming to synchronously solve the problems of shading, heat insulation, and ventilation energy-saving on the west facade of buildings.

[0008] A shading system is provided on the window body, comprising photovoltaic louvers with adjustable angles, a power rail and a driving device, wherein the photovoltaic louvers can reciprocate along the power rail and can automatically adjust their angles under the drive of the driving device to optimize the light and heat comfort at different times;

[0009] A ventilation system, comprising an upper vent, a lower vent, a green plant unit and an intelligent sprinkler unit; the green plant unit is located at the bottom of the window body, and the intelligent sprinkler unit is arranged corresponding to the green plant unit, and a temperature gradient is formed through the transpiration of the green plant unit and the spraying of the intelligent sprinkler unit, so that the air between the upper vent and the lower vent forms convection to achieve ventilation;

[0010] The control system is electrically connected to the photothermal sensor, the shading system and the ventilation system, and is capable of receiving the light intensity and temperature signals monitored in real time by the photothermal sensor, and automatically adjusting the angle of the photovoltaic louvers of the shading system according to a preset threshold value or algorithm to control the amount of light entering, the opening of the upper vents, and the spraying amount of the intelligent sprinkler unit.

[0011] A further technical solution is that the photovoltaic blinds are equipped with photovoltaic cell films for converting solar energy into electrical energy to power the energy-saving window system, and can be stored in blind boxes on both sides of the window body along the extension direction of the power guide rail; the driving device drives the photovoltaic blinds to rotate along their central axis through a transmission mechanism.

[0012] A further technical solution is that the power rail comprises an upper rail, a lower rail and a sliding assembly, and the upper rail and the lower rail are respectively slidably mounted with the sliding assembly;

[0013] The photovoltaic louver is vertically arranged between the upper guide rail and the lower guide rail, and the two ends are rotatably connected to the sliding components located on the upper guide rail and the lower guide rail respectively;

[0014] The transmission mechanism includes gears that are sequentially connected in transmission, and an electromagnet is fixed on each of the gears. Corresponding to the electromagnet, the upper end of the photovoltaic blind has a magnetic part. The electromagnet is electrically connected to the control system and can control the rotation of the photovoltaic blind through the magnetic force between the electromagnet and the magnetic part.

[0015] A further technical solution is that the sliding assembly includes a slider and a roller, the roller is arranged on both sides of the slider, and the power is connected to a power device inside the slider;

[0016] Rolling grooves corresponding to the rollers are provided on the upper guide rail and the lower guide rail, and sliding grooves corresponding to the sliders are provided. The power device drives the rollers to roll along the rolling grooves so as to drive the sliders to move along the sliding grooves.

[0017] Furthermore, the technical solution lies in that the green plant unit is arranged at the bottom of the window main body through a planting box body. The bottom of the window main body has box body installation grooves distributed in an array, and gaps are left between the multiple box body installation grooves. The gaps form the lower ventilation openings, and the planting box body is connected to the box body installation grooves through mortise and tenon joints.

[0018] Furthermore, the technical solution lies in that the intelligent sprinkler irrigation unit includes a sprinkler pipe and sprinkler heads;

[0019] The sprinkler pipe is fixed on the window main body and is connected to a water source through a valve. The valve is connected to the control system and is used to control the water inflow of the sprinkler pipe;

[0020] The sprinkler heads are evenly distributed on the sprinkler pipe and are arranged corresponding to the openings of the planting box bodies.

[0021] Furthermore, the technical solution lies in that climbing traction ropes are arranged on the left and right sides of the window main body. The multiple climbing traction ropes are in a strip grid shape and are used to guide the climbing of the green plant units in the planting box bodies.

[0022] Furthermore, the technical solution lies in that a movable sealing piece is arranged at the upper ventilation opening.

[0028] When it is determined that the window system needs to be adjusted, control instructions for the shading system, the upper ventilation opening, and the intelligent sprinkler unit are intelligently generated, where the control instructions include, but are not limited to, the opening angle of the photovoltaic louvers, the opening and closing degree of the upper ventilation opening, and the spraying frequency and duration of the intelligent sprinkler unit;

[0029] The digitally processed control instructions are sent to the shading system, the upper ventilation opening, and the intelligent sprinkler unit to control the opening angle or closed state of the photovoltaic louvers of the shading system to adjust the light entering the room, while collecting energy using the photovoltaic effect, adjusting the opening of the upper ventilation opening, and combining the thermal pressure, wind pressure, and chimney effect inside and outside the building to optimize the unilateral ventilation effect of the building; and, controlling the spraying amount of the intelligent sprinkler unit, and automatically adjusting the irrigation strategy according to the water demand of plants and the demand for evaporation and heat dissipation.

The control system takes the optimal value of human thermal comfort and light comfort as the critical point to accurately regulate the indoor light and heat environment. At the same time, the ventilation system uses the transpiration effect of the green plant unit and the spraying effect of the supporting sprinkler system to reduce the temperature at the bottom of the window, forming a natural temperature difference effect, driving air circulation, and realizing natural ventilation. This not only effectively reduces the indoor temperature, reduces the ventilation energy consumption, but also improves the ecologicality and aesthetics of the living space.

Detailed implementation manners

[0039] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0040] This embodiment provides an energy-saving window system based on photothermal coupling and its control method. As Figure 1 and Figure 2 shown, it includes: a window body 1, which is fixed to the wall 9 by bolts and mainly provides a bearing and supporting function. A photothermal sensor 5 for detecting the light intensity and temperature is installed on the window body 1. A plurality of photothermal sensors 5 are fixedly installed in the four directions of the upper, lower, left, and right of the window body 1, which is beneficial to reducing the measurement error.

[0041] A light shading system 2, which is arranged on the front side of the window body 1 and is used to adjust the amount of sunlight incident. It includes adjustable-angle photovoltaic louvers 21, a power guide rail 22, and a driving device 23. The photovoltaic louvers 21 can reciprocate along the power guide rail 22 and can automatically adjust the angle under the drive of the driving device 23 to optimize the photothermal comfort at different times. It should be noted here that the front side specifically refers to the side away from the interior.

[0042] Ventilation system 3, including an upper ventilation opening 31, a lower ventilation opening 32, a green plant unit 4 and an intelligent sprinkler unit 7; the green plant unit 4 is located at the bottom of the window body 1 and is correspondingly arranged with the intelligent sprinkler unit 7, and the intelligent sprinkler unit 7 can provide the water required by the green plant unit 4. The transpiration of the green plant unit 4 and the spraying of the intelligent sprinkler unit 7 can weaken the air temperature at the bottom of the window body 1. At this time, the air above the window form is hotter and the air below is colder. The hot air rises and the cold air descends. After the air pressure inside the window decreases, the external air enters. In this way, air convection will be formed in a cycle, thereby realizing the natural ventilation of the building, saving energy and protecting the environment. Here, it is preferably that the total cross-sectional area of the lower ventilation opening 32 is smaller than the total cross-sectional area of the upper ventilation opening 31, and this design can effectively promote air flow. Specifically, as the hot air rises to the upper part of the window form, due to the larger area of the upper ventilation opening 31, the hot air can be quickly discharged, forming an upward air flow. At the same time, the area of the lower ventilation opening 32 is smaller, and the air inflow speed is slower, forming a natural air flow guide. In this way, when the air density difference is caused by the temperature change inside the window, the pressure difference between the rising hot air and the entering cold air will further accelerate the air flow.

[0043] Under this design, due to the smaller cross-sectional area of the lower ventilation opening 32, the air flow velocity through the lower inlet is higher, causing a strong air flow impact and prompting more external air to enter the room. At the same time, the larger upper ventilation opening 31 can effectively discharge the hot air, making the air convection process smoother, thereby enhancing the ventilation effect. Through this natural ventilation method, the air flow inside the building is more stable and efficient, avoiding the energy loss in the traditional ventilation method and achieving the effect of energy conservation and environmental protection.

[0044] In addition, the design with a smaller lower ventilation opening can also prevent excessive cold air from directly entering the room, thereby reducing the direct impact of cold air and optimizing the indoor temperature regulation effect, further improving the comfort and energy conservation effect.

[0045] Control system 6, connected to the light and heat sensor 5, the shading system 2 and the ventilation system 3, can receive the light intensity and temperature signals real-time monitored by the light and heat sensor 5, and automatically adjust the angle of the photovoltaic louvers 21 of the shading system 2 to control the light input amount, control the opening degree of the upper ventilation opening 31 and the spraying amount of the intelligent sprinkler unit 7 according to the preset threshold or algorithm.

[0046] The functions of the control system 6 here include receiving the data detected by the light and heat sensor 5, and taking the optimal temperature and light intensity of human thermal comfort and light comfort as the control critical points to scientifically regulate the indoor light and heat environment of the building. The setting of the green plant unit 4 not only adds green elements to the living space, improves the ecologicality and aesthetics of the living environment, but also the growth of the green plants can further absorb heat, reduce the surrounding environment temperature, and form a benign ecological cycle.

[0047] In this embodiment, the photovoltaic louvers 21 are covered with a photovoltaic power generation film on the side facing the sun, and the electric energy generated by the power generation film is used to drive the device 23 to supply power. The driving device 23 is fixed on the window main body 1, and a transmission mechanism 24 is arranged between the driving device 23 and the photovoltaic louvers 21 for driving the photovoltaic louvers 21 to rotate along their central axes.

[0048] It should be noted that the above-mentioned photovoltaic louvers 21 are vertically arranged, so for the west-facing sunlight, the shading effect is better than that of horizontal arrangement, and at the same time, it is ensured that the photovoltaic louvers 21 are between the sunlight and the photothermal sensor 5. The power guide rail 22 is a guide rail with a built-in power device. The photovoltaic louvers 21 are installed on the power guide rail 22, and thus can slide along the power guide rail 22. The driving device 23 is fixed on the window main body 1, and of course, it can also be fixed on the power guide rail 22 as long as it does not affect the sliding of the photovoltaic louvers 21.

[0049] The photovoltaic louvers 21 are arranged on the window main body 1 through the power guide rail 22 and can slide along the guide rail, so as to flexibly adjust the shading range, effectively block the glare caused by direct sunlight, and improve the comfort of the living or working environment. The side of the photovoltaic louvers 21 facing the sun is covered with a photovoltaic power generation film, so that while the photovoltaic louvers 21 shade, they can also convert solar energy into electric energy, realizing the recycling of energy and improving the overall energy efficiency of the system. The driving device 23 is fixed on the window main body 1, and a transmission mechanism 24 is arranged between the driving device 23 and the photovoltaic louvers 21, which can drive the photovoltaic louvers 21 to rotate along their central axes. This function enables the shading system 2 to automatically adjust the angles and positions of the photovoltaic louvers 21 according to the position of the sun and the light intensity, realizing intelligent shading control. The control system 6 includes a photothermal processing unit for processing and analyzing the detection data of the photothermal sensor 5, and further realizing more accurate shading adjustment.

[0050] The designs of the power guide rail 22 and the driving device 23 make the shading system 2 have a compact structure, do not occupy too much space, are easy to install and maintain. The setting of the transmission mechanism 24 ensures the stability and reliability of the photovoltaic louvers 21 during the sliding and rotating processes, reducing the failure rate and maintenance cost.

[0051] Combined with Figure 3 In this embodiment, the power guide rail 22 includes an upper guide rail 221, a lower guide rail 222 and a sliding component 223. The upper guide rail 221 and the lower guide rail 222 are respectively slidably installed with the sliding component 223. A plurality of photovoltaic louvers 21 are arranged between the upper guide rail 221 and the lower guide rail 222 to form a louver window structure, and both ends of each photovoltaic louver 21 are rotatably connected to the sliding component 223.

[0052] Combined with Figure 4, the transmission mechanism 24 includes gears 241 that are sequentially connected in transmission. An electromagnet 242 is fixed on each gear 241. Corresponding to the electromagnet 242, the upper end of the photovoltaic louver 21 has a magnetic part 211. The electromagnet 242 is electrically connected to the control system 6 and can control the rotation of the photovoltaic louver 21 through the magnetic force with the magnetic part 211.

[0053] Specifically, the sliding assembly 223 includes a slider 2231 and rollers 2232. The rollers 2232 are arranged on both sides of the slider 2231 and are power-connected to a power device inside the slider 2231. Rolling grooves are provided on the upper guide rail 221 and the lower guide rail 222 corresponding to the rollers 2232, and sliding grooves are provided corresponding to the slider 2231. The power device drives the rollers 2232 to roll along the rolling grooves to drive the slider 2231 to move along the sliding grooves.

[0054] The gears 241 in the transmission mechanism 24 cooperate with the electromagnets 242 to control the rotation of the photovoltaic louvers 21 through magnetic force, realizing the control of the angles of the photovoltaic louvers 21. The structure is stable and highly reliable. The electromagnets 242 are electrically connected to the control system 6 and can automatically adjust the angles and positions of the photovoltaic louvers 21 according to the instructions of the control system 6, realizing the automatic control of the shading system 2.

[0055] The sliding assembly 223 includes a slider 2231 and rollers 2232. The rollers 2232 are arranged on both sides of the slider 2231 and are power-connected to a power device inside the slider 2231. Rolling grooves are provided on the upper guide rail 221 and the lower guide rail 222 corresponding to the rollers 2232, and sliding grooves are provided corresponding to the slider 2231. This structure ensures the smooth movement of the sliding assembly 223 on the guide rail, reduces friction and wear, and improves the reliability of the system. Further enhances the stability of the system.

[0056] Specifically, in this embodiment, the green plant unit 4 is arranged at the bottom of the window main body 1 through the planting box body 41. The bottom of the window main body 1 has box body installation grooves 11 distributed in an array, and there are gaps between the multiple box body installation grooves 11. The gaps form the lower ventilation openings 32, and the planting box body 41 is connected to the box body installation grooves 11 through mortise and tenon joints. There are gaps between the box body installation grooves 11 at the bottom of the window main body 1, and these gaps form the lower ventilation openings 32. This enables air to smoothly enter from the lower ventilation openings 32, forming a natural ventilation path with the upper ventilation openings 31, effectively improving the indoor air quality and reducing the indoor temperature. The planting box body 41 is connected to the box body installation grooves 11 through mortise and tenon joints. This connection method is not only stable and reliable but also convenient for installation and disassembly. When it is necessary to replace, clean, or maintain the planting box body 41, it can be easily taken out from the box body installation grooves 11, improving the convenience of maintenance. The box body installation grooves 11 distributed in an array enable the planting box bodies 41 to be arranged orderly at the bottom of the window main body 1, making full use of the space under the window. It is both beautiful and practical, increasing the greening area and enhancing the overall aesthetic degree of the building. The green plants in the planting box body 41 can obtain sufficient air circulation through the lower ventilation openings 32, which is beneficial to the growth and photosynthesis of the green plants. At the same time, the growth of the green plants can further weaken the temperature at the bottom of the window main body 1, forming a benign ecological cycle. The green plants in the planting box body 41 can play a role in heat insulation and sunshading to a certain extent, reducing the transfer of outdoor heat into the room, thereby reducing the indoor temperature.

[0057] Specifically, in this embodiment, it further includes an intelligent sprinkler irrigation unit 7. The intelligent sprinkler irrigation unit 7 includes a sprinkler pipe 71 and sprinkler heads 72. The sprinkler pipe 71 is fixed on the window main body 1 and is connected to a water source through a valve. The valve is connected to the control system 6 and is used to control the water inflow of the sprinkler pipe 71. The sprinkler heads 72 are evenly distributed on the sprinkler pipe 71 and are arranged corresponding to the openings of the planting box bodies 41.

[0058] The intelligent sprinkler irrigation unit 7 is connected to the control system 6 through a valve, and can precisely control the water inflow and irrigation time of the sprinkler pipe 71. This makes the irrigation process more automated, without the need for manual operation, greatly improving the irrigation efficiency and accuracy. The sprinkler heads 72 are evenly distributed on the sprinkler pipe 71, ensuring that each planting box body 41 can obtain uniform water volume, avoiding problems such as uneven plant growth or water resource waste caused by uneven irrigation. By precisely controlling the irrigation volume through the control system 6, irrigation can be carried out according to the actual water requirements of the plants, avoiding over-irrigation or under-irrigation. This helps to improve the utilization efficiency of water resources.

[0059] Specifically, in this embodiment, climbing vine traction ropes 12 are arranged on the left and right sides of the window main body 1. The multiple climbing vine traction ropes 12 are in a strip grid shape and are used to guide the climbing of the green plant unit 4 in the planting box body 41.

[0060] The climbing traction cable 12 is distributed in a strip grid pattern, providing a clear climbing path for the green plant units 4 in the planting box body 41. It can orderly guide the green plants to climb along the traction cable, avoiding the chaos caused by the random growth of the green plants, and making the entire exterior wall green ecological building structure more beautiful and orderly. Through the guidance of the climbing traction cable 12, the green plants can make more full use of the space on both sides of the window main body 1 to climb and grow. This design not only increases the greening area but also improves the space utilization rate, enabling the building to achieve a greater greening effect within a limited space. The strip grid structure also helps with air circulation, providing good growth conditions for the green plants.

[0061] Specifically, in this embodiment, a movable sealing piece 8 is provided at the upper ventilation opening 31, and the sealing piece 8 is connected to a driver fixed to the window main body 1; the driver is connected to the control system 6 and is used to control the opening degree of the upper ventilation opening 31 or the lower ventilation opening 32.

[0062] The movable sealing piece 8 can respond to the instructions of the control system 6 to open or close the upper ventilation opening 31. The sealing piece 8 can closely fit the edge of the ventilation opening and form an effective sealing barrier when closed, enhancing the heat preservation and waterproof performance of the building.

[0063] In this embodiment, the window main body 1 is fixed to the outside of the wall body 9, and a support frame 10 is provided below to support the window main body 1, making the window main body 1 more stable. Of course, it is not limited to the support fixing method, and a cantilever beam or other methods can also be used.

[0064] A glass inner window is installed on the rear side of the window main body 1, and the glass inner window can be opened and closed. Installing an openable glass inner window on the window main body 1 can be closed when needed to form an additional partition layer, effectively reducing the heat transfer between indoors and outdoors and improving the heat insulation performance of the building.

[0065] In summary, the specific control method of this embodiment is as follows:

[0066] Real-time receive the light intensity and temperature data detected by at least one of the photothermal sensors 5;

[0067] Preprocess the received light intensity and temperature data, and dynamically compare and analyze the light intensity and temperature values with the thresholds preset according to the building environment and user requirements;

[0068] According to the comparison and analysis results, judge whether the current light and temperature conditions reach or exceed the preset critical value to determine whether it is necessary to adjust the operating state of the window system;

[0069] When it is determined that the window system needs to be adjusted, control instructions for the shading system 2, the upper ventilation opening 31, and the intelligent sprinkler unit 7 are intelligently generated. The control instructions include, but are not limited to, the opening angle of the photovoltaic louvers 21, the opening and closing degree of the upper ventilation opening 31, and the spraying frequency and duration of the intelligent sprinkler unit 7.

[0070] The digitally processed control instructions are sent to the shading system 2, the upper ventilation opening 31, and the intelligent sprinkler unit 7 to control the opening angle or closed state of the photovoltaic louvers 21 of the shading system 2 to adjust the amount of light entering the room, and at the same time, energy is collected using the photovoltaic effect. The opening degree of the upper ventilation opening 31 is adjusted, and the single-sided ventilation effect of the building is optimized by combining the thermal pressure, wind pressure, and chimney effect inside and outside the building. In addition, the spraying amount of the intelligent sprinkler unit 7 is controlled, and the irrigation strategy is automatically adjusted according to the water demand of the plants and the demand for evaporation and heat dissipation.

[0071] The control of the shading system 2 is implemented based on the average light intensity in the past 10 minutes. Specifically, when the average light intensity in the past 10 minutes is ≤ 300 LUX, the control unit sends an electrical signal to the power device that controls the power guide rail 22, and the power device drives the photovoltaic louvers 21 to be retracted into the boxes on both sides of the window body 1. When the average light intensity in the past 10 minutes ≥ 600 LUX, the control unit sends an electrical signal to the power device that controls the power guide rail 22, and the power device drives the photovoltaic louvers 21 to slide out of the boxes on both sides of the window body 1 and unfold into a louver window structure, and the angle of the photovoltaic louvers 21 is automatically adjusted by the driving device 23 so that the average light intensity is between 300 LUX and 600 LUX.

[0072] The control of the ventilation system is implemented based on the average temperature in the past 10 minutes. Specifically, when the average temperature in the past 10 minutes ≥ 35 °C, the control unit sends an electrical signal to the driver that controls the upper ventilation opening 31 and the valve of the intelligent sprinkler unit 7, and adjusts the upper ventilation opening 31 to the open state, and at the same time, the intelligent sprinkler unit 7 starts spraying. When the average temperature in the past 10 minutes ≤ 35 °C, the control unit sends an electrical signal to the driver that controls the upper ventilation opening 31 and the valve of the intelligent sprinkler unit 7, and adjusts the upper ventilation opening 31 to the closed state, and at the same time, the intelligent sprinkler unit 7 stops spraying.
