Description

Technical Field

[0001] This application relates to the fields of intelligent building and building energy conservation technology, and more specifically, to a thermosensitive retroreflective intelligent wall with switchable working configuration. Background Technology

[0002] In contemporary architecture, glass curtain walls have become a widely used building envelope due to their superior light transmission and modern aesthetic appeal. However, their significant shortcomings in regulating solar radiation have led to a series of problems related to energy consumption, comfort, and light pollution. For example, while widely used tinted glass can block some solar radiation, its primary mechanism is heat absorption, which causes a significant increase in the glass's own temperature. This heat is then transferred into the interior through secondary radiation and convection, resulting in limited insulation and potentially exacerbating indoor heat load. While heat-reflective coated glass can reflect some sunlight, it cannot adapt to the dynamic solar radiation requirements of buildings under different seasons and weather conditions. Furthermore, the high reflectivity of glass curtain walls transforms sunlight into a giant directional mirror, projecting intense light onto surrounding streets and buildings, creating glare that severely impacts the visual comfort and health of pedestrians, drivers, and users of nearby buildings.

[0003] Therefore, the core deficiency of existing glass curtain wall technology lies in the lack of an "intelligent" capability that can respond to environmental changes in real time and actively adjust its thermal and optical properties. This makes it difficult to achieve a dynamic balance between the often conflicting needs of lighting, views, insulation, and heat gain. Therefore, to improve the overall performance of buildings and effectively reduce energy consumption, it is necessary to research a glass curtain wall technology with intelligent adjustment capabilities to achieve precise control of solar radiation under different environmental conditions. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a thermosensitive retroreflective smart wall with switchable working configuration, which addresses the shortcomings of the prior art.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A thermosensitive retroreflective smart wall with switchable working configuration, the thermosensitive retroreflective smart wall comprising a wall frame, multiple functional panels located within the wall frame, a control unit, and a drive mechanism, wherein:

[0006] The multiple functional panels are arranged side by side in the form of louvers within the wall frame and have two main surfaces. The first main surface is a retroreflective functional layer for directional reflection of incident solar radiation along the original incident direction, and the second main surface is an electrochromic functional layer whose transmittance can be dynamically adjusted based on an electronic control signal.

[0007] The control unit is used to generate a drive signal based on the outdoor ambient temperature by comparing a preset temperature threshold with a multimodal thermal response dynamic adjustment algorithm, and send the signal to the drive mechanism, which then switches the orientation of the first main surface of each functional board according to the drive signal.

[0008] The control unit is also used to identify the control mode to be triggered based on the outdoor ambient temperature and a preset temperature threshold, and to generate an electronic control signal and send an electronic control signal to the electrochromic functional layer to dynamically adjust its light transmission state.

[0009] Furthermore, the retroreflective functional layer is a microprism array thin film, which is composed of a large number of tiny prism units arranged closely together.

[0010] Furthermore, the thermal retroreflective smart wall also includes a temperature monitoring module, which monitors the outdoor ambient temperature and transmits the real-time temperature data to the control unit, which then generates corresponding drive signals and electrical control signals based on the real-time temperature data.

[0011] Furthermore, the control unit generates a drive signal according to the following steps:

[0012] (1) Obtain outdoor ambient temperature data and compare the data with a preset temperature threshold to obtain the temperature comparison result;

[0013] (2) Based on the temperature comparison results and the mechanical performance indicators of the drive mechanism, a multi-dimensional collaborative control parameter set is calculated by the multi-modal thermal response dynamic adjustment algorithm, and a drive signal is generated by using the parameter set through a preset mapping rule. The mechanical performance indicators include steady-state error, fatigue life and temperature rise coefficient. The dimensions of the multi-dimensional collaborative control parameter set include, but are not limited to, target orientation angle, dynamic adjustment rate and execution priority.

[0014] Furthermore, the multi-dimensional collaborative control parameter set is calculated using the following formula:

[0015] (1) The angular deviation caused by mechanical thermal deformation due to temperature is corrected by the following formula:

[0016] ;

[0017] in, Indicates the angle of the target's orientation. From the perspective of theoretical objectives, Indicates steady-state error. This indicates outdoor ambient temperature data. This indicates the preset temperature threshold. Indicates the coefficient of thermal expansion of the material;

[0018] (2) The dynamic adjustment rate is calculated based on fatigue life using the following formula:

[0019] ;

[0020] in, Indicates the dynamic adjustment rate. Indicates the rated speed of the drive mechanism. Indicates fatigue life. This indicates the fatigue life warning threshold;

[0021] (3) Calculate the execution priority using the following formula:

[0022] ;

[0023] in, This indicates the execution priority of the i-th function board. Indicates the temperature rise coefficient. Indicates the current angle error. These correspond to the weighting coefficients for temperature rise effect, lifespan status, and angle error, respectively. This represents the sum of all weight coefficients.

[0024] Furthermore, the control unit generates an electronic control signal according to the following steps:

[0025] (1) Based on the comparison of preset temperature thresholds, identify the control mode to be triggered. The control module includes full light transmission mode, privacy mode, high temperature reflection mode and shading mode.

[0026] (2) Based on the identified control mode, the control unit retrieves the control voltage value corresponding to the mode from the preset parameter library, and, in combination with the specifications of the electrochromic functional layer, fine-tunes and optimizes the retrieved control voltage value to generate an electronic control signal for the electrochromic functional layer.

[0027] Furthermore, the light transmittance of the electrochromic functional layer is dynamically adjusted in the following ways:

[0028] (1) When the control unit determines whether the full light transmission mode or the shading mode needs to be triggered, it generates a first electronic control signal corresponding to the target fading voltage. The first electronic control signal is used to control the magnitude and duration of the voltage applied to the electrochromic functional layer, drive ions to be extracted from the electrochromic layer, and make the glass change to a transparent state.

[0029] (2) When the control unit determines the current required privacy mode or high temperature reflection mode, it generates a second electronic control signal corresponding to the target coloring voltage. The second electronic control signal is used to regulate the voltage intensity and duration applied to the electrochromic functional layer to ensure that ions are injected into the electrochromic layer at a predetermined rate and distribution, so that the glass is transformed into a colored state.

[0030] Furthermore, in the full-transparency mode, the glass state of the electrochromic functional layer changes to a transparent state, and the retroreflective functional layer of each functional panel is driven inward by the drive mechanism. At this time, the retroreflective functional layer does not function, and the main body of the wall is transparent electrochromic glass.

[0031] In privacy mode, the glass state of the electrochromic functional layer changes to a colored state, and the retroreflective functional layer of each functional panel is driven inward by the driving mechanism. At this time, the wall is in a unidirectional colored state, which achieves sun shading by absorbing solar radiation.

[0032] In high-temperature reflection mode, the glass state of the electrochromic functional layer changes to the colored state, and the retroreflective functional layer of each functional plate is driven outward by the driving mechanism. At this time, the incident solar radiation will first come into contact with the retroreflective functional layer, so that the incident solar radiation is reflected back along the original direction, blocking the entry of heat.

[0033] In shading mode, the glass state of the electrochromic functional layer changes to a transparent state, and the retroreflective functional layer of each functional panel is driven outward by the driving mechanism. At this time, a highly reflective barrier is formed by the retroreflective functional layer to achieve the shading effect.

[0034] The beneficial effects of this invention are:

[0035] (1) By dynamically adjusting the orientation of the functional panel and the light transmittance of the electrochromic functional layer according to the outdoor ambient temperature by the control unit, the amount of solar radiation entering the room can be reasonably controlled in different seasons and time periods. For example, in the high temperature of summer, the retroreflective functional layer is turned outward to reflect a large amount of solar radiation back, reducing the amount of heat entering the room and reducing the air conditioning cooling load; in the cold winter, more solar radiation is allowed to enter the room through the electrochromic functional layer, increasing the indoor heat and reducing the heating energy consumption, thereby achieving a significant reduction in building energy consumption;

[0036] (2) According to different control modes, such as full light transmission mode and shading mode, the light transmission and reflection performance of the wall are precisely adjusted to make the utilization of solar radiation more efficient. When natural lighting is needed, switch to full light transmission mode to make full use of natural light and reduce the use of artificial lighting; when shading is needed, adjust in time to avoid energy waste caused by excessive lighting and improve energy utilization efficiency.

[0037] (3) By using retroreflective materials to achieve directional reflection, the heat transfer path of "absorption-re-radiation" of traditional materials is fundamentally avoided, which can significantly reduce the heat exchange between indoor and outdoor areas and greatly improve the thermal insulation performance of buildings.

[0043] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0044] like Figure 1 and Figure 2 As shown, this application discloses a thermosensitive retroreflective smart wall with switchable working configuration. The thermosensitive retroreflective smart wall includes a wall frame 1, multiple functional panels 2 located within the wall frame, a drive mechanism 3, and a control unit 4, wherein:

[0045] The multiple functional panels 2 are arranged in parallel in the form of louvers within the wall frame 1, and have two main surfaces. The first main surface 21 is a retroreflective functional layer for directional reflection of incident solar radiation along the original incident direction, and the second main surface 22 is an electrochromic functional layer whose transmittance can be dynamically adjusted based on an electronic control signal.

[0046] The control unit 4 is used to generate a drive signal based on the outdoor ambient temperature by comparing a preset temperature threshold and a multimodal thermal response dynamic adjustment algorithm, and send it to the drive mechanism 3. The drive mechanism 3 then switches the orientation of the first main surface 21 of each function board according to the drive signal.

[0047] The control unit 4 is also used to identify the control mode to be triggered based on the outdoor ambient temperature and a preset temperature threshold, and to generate an electronic control signal and send an electronic control signal to the electrochromic functional layer to dynamically adjust its light transmission state.

[0048] As can be seen from the above, the thermosensitive retroreflective smart wall with switchable working configuration disclosed in this application dynamically adjusts the orientation of the functional panels and the light transmission state of the electrochromic functional layer according to the outdoor ambient temperature through the control unit, enabling reasonable control of the amount of solar radiation entering the room in different seasons and time periods. For example, in the high temperatures of summer, the retroreflective functional layer faces outward, reflecting a large amount of solar radiation back, reducing heat entering the room and lowering the air conditioning cooling load; in the cold winter, more solar radiation is allowed to pass through the electrochromic functional layer into the room, increasing indoor heat and reducing heating energy consumption, thereby achieving a significant reduction in building energy consumption; according to different control modes, such as full-transparency mode and shading mode, the light transmission and reflection performance of the wall are precisely adjusted, making the utilization of solar radiation more efficient. When natural lighting is needed, it switches to full-transparency mode to make full use of natural light and reduce the use of artificial lighting; when shading is needed, it is adjusted in time to avoid energy waste caused by excessive lighting and improve energy utilization efficiency. By using retroreflective materials to achieve directional reflection, the traditional heat transfer path of "absorption-re-radiation" is fundamentally avoided, which can significantly reduce indoor and outdoor heat exchange and greatly improve the thermal insulation performance of buildings.

[0049] In one embodiment, the retroreflective functional layer is a microprism array thin film, which is composed of a large number of tiny prism units arranged closely together.

[0050] Specifically, each prism unit has a precisely designed geometry and angles (such as an equilateral triangular prism structure or a square pyramid shape), and its surface undergoes special treatment to possess high reflectivity optical characteristics. This compact structure not only ensures the mechanical strength and stability of the thin film but also effectively reduces light absorption loss within the film, reflecting more incident solar radiation back. In summary, this application achieves directional reflection by employing retroreflective materials, fundamentally avoiding the traditional "absorption-reradiation" heat transfer path.

[0051] In one embodiment, please refer to Figure 2 The thermal retroreflection smart wall also includes a temperature monitoring module 5, which monitors the outdoor ambient temperature and transmits the real-time temperature data to the control unit 4. The control unit 4 then generates corresponding drive signals and electrical control signals based on the real-time temperature data.

[0052] Specifically, the temperature monitoring module employs multiple high-precision temperature sensors distributed across different locations on the exterior of the wall to comprehensively and accurately capture changes in outdoor ambient temperature. These temperature sensors feature rapid response and high sensitivity, enabling them to promptly detect and reliably transmit the collected real-time temperature data to the control unit via wired or wireless communication. The control unit then analyzes and processes the received real-time temperature data, combining it with preset temperature thresholds and control strategies to generate corresponding drive and electronic control signals. This allows for the orientation of any side towards the outside, and, combined with the state changes of the electrochromic functional layer, establishes four basic operating modes: full light transmission, sun shading, high temperature, and privacy. This solution creatively upgrades passive design (i.e., fixed orientation) to an active programmable system, enabling a single wall to address varying energy-saving, lighting, ventilation, and privacy needs throughout the year.

[0053] In one embodiment, please refer to Figure 3 The control unit generates the drive signal according to the following steps:

[0054] (1) Obtain outdoor ambient temperature data and compare the data with the preset temperature threshold to obtain the temperature comparison result.

[0055] Specifically, when acquiring outdoor ambient temperature data, a pre-set temperature monitoring module (which can be a high-precision digital temperature sensor, a thermistor sensor, or an integrated temperature sensor) collects the current outdoor ambient temperature value in real time. This temperature monitoring module possesses high accuracy and fast response characteristics, ensuring that the collected data accurately reflects the actual outdoor temperature. Subsequently, the application compares the collected temperature data with a preset temperature threshold. This preset temperature threshold is not fixed but flexibly set according to different seasons, equipment operating modes, and user needs. For example, in summer cooling mode, the temperature threshold is set to a relatively low value to ensure that the indoor temperature quickly reaches a comfortable level; while in winter heating mode, the temperature threshold is set to a relatively high value. By comparing the collected temperature data with the corresponding temperature threshold, a temperature comparison result is obtained, indicating whether the current outdoor ambient temperature is higher than, lower than, or equal to the preset threshold.

[0056] (2) Based on the temperature comparison results and the mechanical performance indicators of the drive mechanism, a multi-dimensional collaborative control parameter set is calculated by the multi-modal thermal response dynamic adjustment algorithm, and a drive signal is generated by using the parameter set through a preset mapping rule. The mechanical performance indicators include steady-state error, fatigue life and temperature rise coefficient. The dimensions of the multi-dimensional collaborative control parameter set include, but are not limited to, target orientation angle, dynamic adjustment rate and execution priority.

[0057] Specifically, the multimodal thermal response dynamic adjustment algorithm comprehensively considers the degree of temperature difference reflected in the temperature comparison results and various parameters of the mechanical performance indicators of the drive mechanism. For steady-state error, the algorithm analyzes the deviation between the actual output and theoretical output of the drive mechanism under different temperature conditions, ensuring that this deviation is minimized when generating control parameters to improve control accuracy. For fatigue life, the algorithm rationally adjusts the dynamic adjustment rate based on the remaining fatigue life to achieve a balance between lifespan and performance optimization. For the temperature rise coefficient, since the drive mechanism itself will generate a temperature rise under varying temperature conditions, the temperature rise coefficient reflects the rate and magnitude of the temperature rise. Based on this, this application comprehensively considers the influence of temperature rise, lifespan status, and angle error, and dynamically coordinates the relationship between various control parameters by establishing a multi-parameter correlation model.

[0058] In one embodiment, the multi-dimensional collaborative control parameter set is calculated using the following formula:

[0059] (1) The angular deviation caused by mechanical thermal deformation due to temperature is corrected by the following formula:

[0060] ;

[0061] in, Indicates the angle of the target's orientation. From the perspective of theoretical objectives, Indicates steady-state error. This indicates outdoor ambient temperature data. This indicates the preset temperature threshold. This represents the coefficient of thermal expansion of the material.

[0062] Specifically, this formula is based on the principle of thermal expansion and takes into account the effect of temperature changes on mechanical structures. It considers that materials expand or contract with temperature changes, resulting in changes in the dimensions and angles of the mechanical structure. Therefore, the formula uses the coefficient of thermal expansion of the material... To quantify this change.

[0063] (2) The dynamic adjustment rate is calculated based on fatigue life using the following formula:

[0064] ;

[0065] in, Indicates the dynamic adjustment rate. Indicates the rated speed of the drive mechanism. Indicates fatigue life. This indicates the fatigue life warning threshold.

[0066] Specifically, this formula is based on the concept of fatigue life, when the remaining life... Approaching or below the warning threshold At that time, by reducing the dynamic adjustment rate To extend the service life of mechanical structures.

[0067] (3) Calculate the execution priority using the following formula:

[0068] ;

[0069] in, This indicates the execution priority of the i-th function board. Indicates the temperature rise coefficient. Indicates the current angle error. These correspond to the weighting coefficients for temperature rise effect, lifespan status, and angle error, respectively. This represents the sum of all weight coefficients.

[0070] Specifically, the weighting coefficients for each component are determined through extensive experimental analysis and simulation optimization based on the actual operating conditions and historical data of the drive mechanism. This application establishes a multi-parameter correlation model to quantitatively correlate parameters such as temperature rise influence, lifespan status, and angle error. By dynamically coordinating the relationships between various control parameters, the drive mechanism can achieve optimal control effects and performance under different temperature environments and usage stages. While ensuring angle control accuracy, it can also take into account the lifespan and temperature rise control of the drive mechanism, thereby improving the overall system stability and reliability.

[0071] In one embodiment, please refer to Figure 3 The control unit generates the electronic control signal according to the following steps:

[0072] (1) Based on the comparison of preset temperature thresholds, identify the control mode to be triggered. The control module includes full light transmission mode, privacy mode, high temperature reflection mode and shading mode.

[0073] Specifically, this application determines the specific mode to be entered by judging whether the temperature threshold, light intensity, and day / night conditions corresponding to the full-transparency mode, privacy mode, high-temperature reflection mode, or shading mode are met. For example, when the outdoor ambient temperature is lower than the preset low-temperature threshold, the light intensity is weak, and it is daytime, the conditions for the full-transparency mode are met. The control unit triggers this mode, causing the electrochromic functional layer to present its maximum light transmittance. In this mode, the transmission of sunlight is maximized, allowing sufficient visible light and solar radiation heat energy to enter the room. When the outdoor ambient temperature is higher than the preset high-temperature threshold and the light intensity is extremely high, the conditions for the high-temperature reflection mode are met. The control unit triggers this mode, causing the electrochromic functional layer to color, and simultaneously controls the wall to flip so that the retroreflective layer faces outward, reflecting most of the solar radiation back and blocking heat from entering the room at the source.

[0074] (2) Based on the identified control mode, the control unit retrieves the control voltage value corresponding to the mode from the preset parameter library, and, in combination with the specifications of the electrochromic functional layer, fine-tunes and optimizes the retrieved control voltage value to generate an electronic control signal for the electrochromic functional layer.

[0075] Specifically, this application will monitor the temperature of the electrochromic functional layer in real time. and compare it with the standard operating temperature Compare them. If there are This indicates that the ion migration rate is accelerated, which may lead to excessively rapid or uneven color changes. In this case, this application will use the following formula: For the obtained initial voltage value Fine-tuning and optimization (wherein, (This is an empirical coefficient) to slow down ion migration and make color changes more stable. If there is... This indicates that the ion migration rate has slowed down. In this case, this application will use the following formula: For the obtained initial voltage value Fine-tuning and optimization were performed to accelerate ion migration and ensure that the color change was completed on time.

[0076] In one embodiment, the light transmittance of the electrochromic functional layer is dynamically adjusted in the following manner:

[0077] (1) When the control unit determines whether the current desired triggering mode is full light transmission mode or shading mode, it generates a first electronic control signal corresponding to the target fading voltage. The first electronic control signal is used to control the magnitude and duration of the voltage applied to the electrochromic functional layer, driving ions to be extracted from the electrochromic layer, so that the glass becomes transparent.

[0078] Specifically, the control unit first selects the initial voltage value of the fading process corresponding to the full light transmission mode or the shading mode from the preset parameter library. Then, it fine-tunes and optimizes the obtained initial voltage value according to the specifications of the electrochromic functional layer (such as ion migration speed) so that the glass can quickly and without local differences transform into a transparent state.

[0079] (2) When the control unit determines the current required privacy mode or high temperature reflection mode, it generates a second electronic control signal corresponding to the target coloring voltage. The second electronic control signal is used to regulate the voltage intensity and duration applied to the electrochromic functional layer to ensure that ions are injected into the electrochromic layer at a predetermined rate and distribution, so that the glass is transformed into a colored state.

[0080] Specifically, the control unit first determines the initial tinting voltage value corresponding to the privacy mode or the high-temperature reflection mode. Then, based on the specifications of the electrochromic functional layer (see the aforementioned content for details, which will not be repeated here), it optimizes the initial tinting voltage value so that the glass can reliably transition to the tinted state.

[0081] In one embodiment, in the full-transparency mode, the glass state of the electrochromic functional layer changes to a transparent state, and the retroreflective functional layer of each functional panel is driven inward by the driving mechanism. At this time, the retroreflective functional layer does not function, and the main body of the wall is transparent electrochromic glass.

[0082] Specifically, this configuration aims to maximize sunlight transmission, allowing ample visible light and solar radiation heat to enter the interior. It is particularly suitable for winter, cloudy or rainy days, or occasions requiring excellent visibility, effectively utilizing solar energy to provide free indoor lighting and heating. In this configuration, the retroreflective layer is inactive, and the main body of the wall is transparent electrochromic glass, ensuring unobstructed views and maximizing sunlight transmission.

[0083] In privacy mode, the glass state of the electrochromic functional layer changes to a colored state, and the retroreflective functional layer of each functional panel is driven inward by the driving mechanism. At this time, the wall is in a unidirectional colored state, which achieves sun shading by absorbing solar radiation.

[0084] Specifically, this configuration integrates both absorption and reflection heat insulation mechanisms. The retroreflective film provides the primary heat reflection barrier externally, while the tinted electrochromic glass acts as a visual barrier and assists in heat absorption internally. Working together, they effectively prevent indoor views from escaping and protect user privacy while achieving high-efficiency heat insulation performance at all times, making it suitable for nighttime use or locations with extremely high privacy requirements. In this configuration, the wall is unidirectionally tinted, absorbing solar radiation to provide shading while maintaining a partially obscured view of the outside.

[0085] In high-temperature reflection mode, the glass state of the electrochromic functional layer changes to a colored state, and the retroreflective functional layer of each functional panel is driven outward by the driving mechanism. At this time, the incident solar radiation will first come into contact with the retroreflective functional layer, causing the incident solar radiation to be reflected back along the original direction, blocking the entry of heat.

[0086] Specifically, in this configuration, the retroreflective functional layer directly and directionally reflects the vast majority of solar radiation (including visible and near-infrared light) back into the atmosphere, physically blocking the heat transfer path through the window. Since the electrochromic glass itself is in a non-heat-absorbing state, the overall system temperature rise is minimal, thus achieving the strongest heat insulation effect under extreme summer temperatures and strong radiation conditions, significantly reducing indoor heat gain and air conditioning load. At this time, the incident solar radiation first comes into contact with the retroreflective functional layer, whose microprism structure reflects most of the solar radiation (including visible and near-infrared light) back along its original direction, effectively blocking heat entry at the source.

[0087] In shading mode, the glass state of the electrochromic functional layer changes to a transparent state, and the retroreflective functional layer of each functional panel is driven outward by the driving mechanism. At this time, a highly reflective barrier is formed by the retroreflective functional layer to achieve the shading effect.

[0088] Specifically, in this working configuration, the glass reduces the amount of light and heat entering the room by absorbing some of the solar radiation, effectively preventing glare and providing moderate shading in non-extremely hot weather, while retaining some outward view.

[0089] In one embodiment, in addition to following the above execution logic, it is also possible to access the current region's weather data and time data, and follow the following logical flow:

[0090] (1) In summer working conditions and if the next day is predicted to be sunny and hot, the system can be automatically set to high temperature reflection mode in the early morning to block solar radiation in advance.

[0091] (2) In winter or cold and cloudy weather, the system will be automatically set to full light transmission mode to maximize the use of possible solar radiation heat gain.

[0092] In one embodiment, in high-temperature reflection mode, if the outdoor temperature is detected to have dropped to a comfortable range, it can automatically switch back to "shade mode" or "full light transmission mode" to avoid unnecessary light loss. Additionally, a scheduled task can be set, such as automatically switching to "privacy and heat insulation mode" before leaving get off work each day.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The thermal retroreflective smart wall according to claim 7, characterized in that, In full-transparency mode, the glass state of the electrochromic functional layer changes to a transparent state, and the retroreflective functional layer of each functional panel is driven inward by the drive mechanism. At this time, the retroreflective functional layer does not function, and the main body of the wall is transparent electrochromic glass. In privacy mode, the glass state of the electrochromic functional layer changes to a colored state, and the retroreflective functional layer of each functional panel is driven inward by the driving mechanism. At this time, the wall is in a unidirectional colored state, which achieves sun shading by absorbing solar radiation. In high-temperature reflection mode, the glass state of the electrochromic functional layer changes to the colored state, and the retroreflective functional layer of each functional plate is driven outward by the driving mechanism. At this time, the incident solar radiation will first come into contact with the retroreflective functional layer, so that the incident solar radiation is reflected back along the original direction, blocking the entry of heat. In shading mode, the glass state of the electrochromic functional layer changes to a transparent state, and the retroreflective functional layer of each functional panel is driven outward by the driving mechanism. At this time, a highly reflective barrier is formed by the retroreflective functional layer to achieve the shading effect.
