Description
Technical Field
[0001] The invention relates to the technical field of building exterior enclosures, and in particular to a building exterior enclosure system that is adaptive to climate change. Background Art
[0002] Building envelope systems play an important role in regulating the flow of energy between indoors and outdoors. Their adaptability to climate change is directly related to the comfort of the indoor environment and the efficiency of energy consumption. External climate conditions are complex and diverse, including multiple factors such as solar radiation, temperature, humidity, airflow and precipitation, and these factors change over time, showing differences in day and night, seasons and regions. These changes bring challenges to building envelope systems.
[0003] In order to ensure indoor comfort and significantly reduce building energy consumption, buildings need to actively adapt to the external climate, take advantage of favorable climate factors, and resist unfavorable factors. For example, traditional ventilated exterior skin systems achieve thermal pressure ventilation through upper and lower vents, remove heat accumulated in the cavity during summer or high temperature periods during the day, reduce heat transfer in the indoor environment, and achieve energy saving effects. However, the limitations of traditional structures often mean that they can only respond to a single climate problem, and cannot achieve a balanced consideration of different climate conditions, thus failing to achieve the optimization of performance and energy saving.
[0004] As the interface between the building and the external environment, the performance of the building envelope system is directly related to the energy efficiency and environmental adaptability of the building. With the development of smart materials and sensing technology, the building envelope system has begun to have a certain degree of dynamic adjustment capabilities, but the existing building envelope system still does not respond well to climate change, lacking true adaptability and predictability. The flexibility of its envelope structure design still needs to be strengthened to better adapt to the climate. Summary of the invention
[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a climate change adaptive building envelope system that solves the problems of poor adaptability and low energy efficiency of the building envelope system in the prior art.
[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is: a building enclosure system that is adaptive to climate change, comprising a frame and a controller, wherein an intelligent sensing device, a dynamic adjustment mechanism and an energy collection and conversion device are arranged on the frame; the intelligent sensing device, the dynamic adjustment mechanism and the energy collection and conversion device are electrically connected to the controller;
[0007] The intelligent sensing device includes a sensor node arranged on a frame;
[0008] The dynamic adjustment mechanism includes an electrochromic glass and a variable sunshade member disposed on a frame;
[0009] The energy collection and conversion device comprises a solar photovoltaic panel, a thermoelectric conversion device and an electrical storage device arranged on a variable sunshade component.
[0010] The beneficial effects of the present invention are as follows: the introduction of intelligent sensing devices enables the building envelope system to have the ability to respond to changes in the external environment in real time. As the "nerve endings" of intelligent perception, the sensor nodes can accurately capture multiple climate data such as temperature, humidity, light, wind speed, etc. The data is processed and analyzed by the controller to provide a decision-making basis for the dynamic adjustment mechanism.
[0011] The dynamic adjustment mechanism optimizes the lighting environment and thermal comfort inside the building. Under strong light, the electrochromic glass will automatically deepen its color, reduce light transmission, and avoid indoor overheating and glare problems; at the same time, the variable sunshade components will unfold to block direct sunlight, effectively reducing the indoor temperature. Conversely, when the light is insufficient or the temperature is low, the glass will become lighter to increase light transmittance, and the sunshade components will shrink to allow more sunlight to enter the room. The dynamic adjustment function not only improves the living experience of the building, but also helps to reduce the operating load of energy-consuming equipment such as air conditioners, achieving the goal of energy conservation and emission reduction.
[0012] The integration of energy collection and conversion devices makes the building envelope system an efficient energy "producer". Solar photovoltaic panels can convert abundant solar energy into electrical energy, providing electrical energy for the operation of electrochromic glass and variable shading components, so that the building envelope system can maintain normal operation without relying on external energy, which helps to reduce energy consumption and carbon emissions.
[0013] Furthermore, in the above-mentioned adaptive climate change building envelope system, the variable sunshade component includes a slide arranged on a frame, an actuating structure is arranged inside the slide; at least two slides are arranged, a sunshade is arranged between the two connected slides, the sunshade is slidably connected to the slide, and a solar photovoltaic panel is arranged on the outer side of the sunshade.
[0014] The beneficial effects of adopting the above further solution are: the design of the slide allows the sunshade to move smoothly when needed, so that the sunshade can be adjusted in real time according to the angle and intensity of sunlight. The sensor node collects and transmits the climate data to the controller, and the controller processes the data and issues instructions to the variable sunshade component, so that it can accurately perform the sunshade action under the instructions of the controller, ensuring that the indoor lighting environment is always in the best state.
[0015] Solar photovoltaic panels are installed on the outside of the sunshade, combining the two functions of sunshade and energy collection. On the one hand, while the sunshade effectively blocks excessive sunlight from entering the room, the solar photovoltaic panels on the outside can efficiently absorb and utilize the sunlight and convert it into electrical energy, which not only improves the efficiency of energy collection, but also maximizes energy utilization. Since the sunshade can be moved as needed, it means that the solar photovoltaic panel can adjust its angle and position as the sunshade moves to better align with the sunlight, thereby improving the efficiency of energy collection.
[0016] Furthermore, in the above-mentioned adaptive climate change building exterior enclosure system, a sliding shaft is arranged between two connected slides, a snap-in plate is arranged on the sliding shaft, the snap-in plate is fixedly connected to the sun visor, connecting plates are arranged on both sides of the sun visor, a support shaft is arranged on the connecting plate, and the support shaft is slidably connected to the slide.
[0017] The beneficial effects of adopting the above further solution are as follows: the sliding shaft, as a key component connecting the two slideways, not only ensures the smooth sliding of the sun visor between the slideways, but also enhances the overall rigidity of the sun visor through the fixed connection between the snap-on plate and the sun visor. The connection plates and support shafts on both sides of the sun visor disperse the force on the sun visor when it is moving or stationary, and improve the bearing capacity of the entire system.
[0018] Furthermore, in the above-mentioned adaptive climate change building exterior protection system, the sensor nodes include temperature sensors, humidity sensors, light intensity sensors and wind speed sensors.
[0019] Furthermore, in the above-mentioned climate-adaptive building exterior enclosure system, a weather-resistant adhesive layer is provided at the connection between the sunshade and the sliding shaft.
[0020] The beneficial effects of adopting the above further solution are: the weather-resistant glue has good waterproof performance, which can effectively prevent moisture from penetrating into the building through the connection between the sunshade and the sliding shaft. The weather-resistant glue has excellent anti-aging and anti-ultraviolet properties, and can effectively resist the aging effect caused by sunlight.
[0021] Furthermore, in the above-mentioned climate-adaptive building envelope system, the solar photovoltaic panels are flexible photovoltaic solar panels.
[0022] The beneficial effects of adopting the above further solution are: the flexible photovoltaic solar panel has the characteristics of being ultra-light and ultra-thin, and can cope with deformations such as bending and twisting, and can even work stably on uneven surfaces. The flexible photovoltaic solar panel is arranged on the outside of the sun visor to reduce the load on the sun visor, improve the overall safety of the sun visor, and can also adapt to the sliding of the sun visor without affecting its conversion efficiency.
[0023] Furthermore, in the above-mentioned climate-adaptive building exterior enclosure system, the sunshade includes an aluminum alloy layer and a heat insulation layer, and the aluminum alloy layer and the flexible photovoltaic solar panel are connected by a sealant.
[0024] The beneficial effects of adopting the above further scheme are: the aluminum alloy layer, with its high strength and excellent weather resistance, provides a solid support for the flexible photovoltaic solar panel, while effectively resisting the erosion of harsh external climate, ensuring the long-term use of the external protection system; the addition of the insulation layer optimizes the thermal insulation performance of the sunshade, effectively reducing the heat exchange between the inside and outside of the building.
[0025] The beneficial effects of the present invention are as follows: the present invention realizes an intelligent, adaptive, environmentally friendly and energy-saving building enclosure system by integrating intelligent sensing devices, dynamic adjustment mechanisms and energy collection and conversion devices. The system can fully and real-time perceive the climate changes in the external environment through multiple sensor nodes arranged on the frame, including temperature sensors, humidity sensors, light intensity sensors and wind speed sensors. Electrochromic glass can automatically adjust the transmittance according to the light intensity, thereby effectively reducing glare and overheating problems while ensuring indoor lighting requirements. The variable sunshade component realizes the adjustable sunshade area through the ingenious combination of components such as slides, actuating structures and sunshades, further enhancing the adaptability of the building enclosure system to climate change. In particular, in the design of the sunshade, not only its sunshade function is taken into consideration, but also the collection and utilization of energy is realized through the solar photovoltaic panels arranged on the outside.

[0031] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.
[0032] like Figures 1 to 4 As shown, this embodiment provides a building envelope system that is adaptive to climate change, which can intelligently sense the external environment, dynamically adjust the building envelope structure, and effectively utilize and convert energy. The system includes a frame 1 and a controller, on which an intelligent sensing device, a dynamic adjustment mechanism, and an energy collection and conversion device are arranged; the intelligent sensing device, the dynamic adjustment mechanism, and the energy collection and conversion device are electrically connected to the controller, and the coordinated operation of each part is realized through the controller. The controller is responsible for receiving data from the intelligent sensing device and controlling the operation of the dynamic adjustment mechanism and the energy collection and conversion device according to the data analysis results.
[0033] The intelligent sensing device includes a sensor node 2 arranged on a frame 1. The sensor node 2 includes a temperature sensor, a humidity sensor, a light intensity sensor and a wind speed sensor. These sensors are distributed on the frame 1 and can fully sense changes in the external environment.
[0034] The energy collection and conversion device includes a solar photovoltaic panel 5, a thermoelectric conversion device and a storage device arranged on the variable sunshade member 4. The solar photovoltaic panel 5 can convert abundant solar energy into electrical energy, and the storage device is used to store the converted electrical energy to provide electrical energy for the operation of the electrochromic glass 3 and the variable sunshade member 4, so that the building envelope system can maintain normal operation without relying on external energy, which helps to reduce energy consumption and carbon emissions.
[0035] The dynamic adjustment mechanism includes an electrochromic glass 3 and a variable sunshade component 4 arranged on the frame 1. The electrochromic glass 3 is a special glass that can change color through the action of an electric field. It is divided into three main electrically controlled dimming glasses: polymer dispersed liquid crystal, suspended particles and electrochromic. In this embodiment, an electrochromic dimming glass is selected, which changes color through the chemical reaction of the electrochromic layer under the action of an electric field. The electrochromic glass 3 is composed of a plurality of thin film layers sandwiched between two substrates, including a transparent conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer and another transparent conductive layer. When a voltage is applied to the electrodes at both ends of the electrochromic element, ions will migrate in or out of the electrochromic layer under the action of an electric field. This migration of ions will cause the valence of the electrochromic material to change, thereby causing a color change. When a state of equilibrium is reached, the color change reaches stability. By adjusting the magnitude and polarity of the applied voltage, the color depth and change speed of the electrochromic glass 3 can be controlled.
[0036] The variable sunshade component 4 includes a slideway 8 arranged on the frame 1, an actuating structure is arranged inside the slideway 8; at least two slideways 8 are arranged, a sunshade 9 is arranged between the two connected slideways 8, the sunshade 9 is slidably connected to the slideway 8, and a solar photovoltaic panel 5 is arranged outside the sunshade 9, and the solar photovoltaic panel 5 is a flexible photovoltaic solar panel. The sunshade 9 includes an aluminum alloy layer 6 and a heat insulation layer 7, and the aluminum alloy layer 6 is connected to the flexible photovoltaic solar panel by a sealant.
[0037] The frame 1, as the supporting structure of the entire sunshade component, needs to have good stability and load-bearing capacity. This embodiment is made of high-strength materials such as steel structure or aluminum alloy material to ensure that it will not be deformed or damaged during use.
[0038] The slideway 8 is a key component for realizing the sliding connection of the sun visor 9. The actuating structure arranged inside the slideway 8 realizes the automatic sliding of the sun visor 9 through the motor and the transmission device. At least two slideways 8 are arranged to ensure that the sun visor 9 can slide freely between two adjacent slideways 8. A weather-resistant adhesive layer is arranged at the connection between the sun visor 9 and the sliding shaft 10. The weather-resistant adhesive has good waterproof performance and can effectively prevent moisture from penetrating into the interior of the building through the connection between the sun visor 9 and the sliding shaft 10.
[0039] like Figure 4 As shown, the sunshade 9 includes an aluminum alloy layer 6 and a heat insulation layer 7. The aluminum alloy layer 6 has good strength and corrosion resistance, and can effectively protect the internal heat insulation layer 7 from damage. The heat insulation layer 7 is made of high-performance heat insulation materials to reduce the impact of solar radiation on indoor temperature. The aluminum alloy layer 6 is connected to the flexible photovoltaic solar panel by a sealant to ensure the sealing and waterproof properties of the connection.
[0040] A sliding shaft 10 is arranged between two connected slideways 8, a snap-in plate 11 is arranged on the sliding shaft 10, the snap-in plate 11 is fixedly connected to the sun visor 9, connecting plates 12 are arranged on both sides of the sun visor 9, a supporting shaft 13 is arranged on the connecting plate 12, the supporting shaft 13 is slidably connected to the slideway 8, and the angle between the supporting shaft 13 and the slideway 8 in the vertical direction can be changed. A weather-resistant adhesive layer is arranged at the connection between the sun visor 9 and the sliding shaft 10, and the weather-resistant adhesive has good waterproof performance and can effectively prevent moisture from penetrating into the interior of the building through the connection between the sun visor 9 and the sliding shaft 10. The weather-resistant adhesive has excellent aging resistance, UV resistance and other properties, and can effectively resist the aging effect caused by sunlight.
[0041] like Figure 2 As shown, when the deformable sunshade member 4 is in the sunshade mode, the sunshade panels 9 are sequentially stacked on the upper end of the frame 1. Figure 1As shown, when the variable sunshade component 4 turns on the sunshade mode, the sunshade plate 9 slides down along the slide 8 in sequence, and changes the angle between the support shaft 13 and the slide 8 in the vertical direction to achieve the sunshade effect.
[0042] The flexible photovoltaic solar panel is composed of resin-encapsulated amorphous silicon as the main photovoltaic element layer, which is laid flat on a base plate made of flexible material, making the solar panel light and flexible, and can be bent and folded at will. A solar photovoltaic panel 5 is arranged on the outside of the sun visor 9, combining the two functions of sunshade and energy collection. On the one hand, while the sun visor 9 effectively blocks excessive sunlight from entering the room, the solar photovoltaic panel 5 on its outside can efficiently absorb and utilize the sunlight and convert it into electrical energy, which not only improves the efficiency of energy collection, but also maximizes energy utilization. Since the sun visor 9 can be moved as needed, it means that the solar photovoltaic panel 5 can adjust its angle and position as the sun visor 9 moves to better align with the sunlight, thereby improving the efficiency of energy collection.
