Description

Technical Field

[0001] This application belongs to the field of energy conservation and environmental protection, specifically relating to an energy-saving window and its energy-saving control method, as well as an intelligent building exterior wall. Background Technology

[0002] Building exterior walls, exposed to direct sunlight during the day, can easily cause indoor temperatures to rise, making people feel stuffy and uncomfortable. As noon approaches, the temperature rise caused by sunlight becomes increasingly severe. This is usually addressed by installing air conditioners to cool the building and maintain a set indoor temperature. However, the use of air conditioners is one of the indirect causes of global climate change, creating a vicious cycle that causes irreparable damage to the environment. To alleviate the problem of rising indoor temperatures due to sunlight and reduce the use of air conditioners, exterior walls (curtain walls) are typically installed on the exterior of buildings. By adjusting the angle of shading, they can achieve the purposes of sun shading and wind and rain protection.

[0003] In existing technologies, solar panels are installed on exterior walls to absorb solar energy and generate electricity while providing shading for the interior, thus enabling intelligent and environmentally friendly buildings. However, the inventors of this application discovered during the research and development process that solar panels generate heat during operation, and if this heat is not dissipated for a long time, it will affect the normal operation of the solar panels. Summary of the Invention

[0004] To at least partially overcome the problems existing in related technologies, this application provides an intelligent building exterior wall device and its control method.

[0005] According to a first aspect of the embodiments of this application, this application provides an energy-saving window, which includes a window frame and a window body, the window frame being installed on an exterior wall facade, the window body being installed on the window frame, and the window body being able to be opened or closed relative to the window frame;

[0006] The window frame is equipped with heat dissipation mechanisms on both sides of its width.

[0007] The window includes a hollow glass shell, in which a solar photovoltaic module is installed. Along the height direction of the hollow glass shell, two or more first heat-conducting pipes are spaced apart on both sides of the width direction of the hollow glass shell. One end of each first heat-conducting pipe protrudes into the interior of the hollow glass shell, and the other end is used to communicate with the heat dissipation mechanism. The first heat-conducting pipes cooperate with the heat dissipation mechanism to exhaust the heat generated by the operation of the solar photovoltaic module into the room or out to the outside.

[0012] Furthermore, the solar altitude angle sensor includes a second base, a scale, and a pointer; the second base is provided with the scale, which has a hemispherical scale groove, and the opening of the scale groove is located on the upper surface of the scale. The concave surface of the scale groove is provided with scale lines, which are strip-shaped photoresistors connected to a microprocessor; the pointer is located at the center of the bottom surface of the scale groove and is perpendicular to the upper surface of the scale.

[0013] In the aforementioned energy-saving window, the window frame is provided with mounting holes, and the window body is installed in the mounting holes;

[0014] The heat dissipation mechanism includes a second heat-conducting pipe, a third heat-conducting pipe, an elastic element, and an opening and closing assembly; along the height direction of the window frame, a second heat-conducting pipe is provided inside on both sides of the window frame where the mounting hole is located in the width direction; along the height direction of the second heat-conducting pipe, two or more third heat-conducting pipes are spaced apart on the side of the second heat-conducting pipe near the mounting hole; one end of the third heat-conducting pipe is connected to the body of the second heat-conducting pipe, and its other end can be connected to the corresponding first heat-conducting pipe when the window is closed relative to the window frame;

[0015] Both ends of the second heat pipe are connected to opening and closing components via the elastic element;

[0016] The window frame has first heat dissipation holes at the top and bottom of the side wall near the outside in the thickness direction, and second heat dissipation holes at the top and bottom of the side wall near the inside in the thickness direction; under the deformation of the elastic element, the opening and closing assembly is used to alternately open or close the first heat dissipation holes and the second heat dissipation holes.

[0017] Furthermore, the opening and closing assembly includes a connecting rod, a first baffle, and a second baffle; the connecting rod adopts a T-shaped structure, in which the opposite ends of the vertical and horizontal rods of the T-shaped structure are connected to the elastic element, one end of the horizontal rod of the T-shaped structure is connected to one end of the first baffle, and along the height direction of the second heat-conducting pipe, the other end of the first baffle extends away from the elastic element; the other end of the horizontal rod of the T-shaped structure is connected to one end of the second baffle, and along the height direction of the second heat-conducting pipe, the other end of the second baffle extends towards the elastic element.

[0019] In the aforementioned energy-saving window, one or more drainage holes are provided at the bottom of the window frame, and a drainage baffle is hinged to the drainage hole.

[0020] According to a second aspect of the embodiments of this application, this application also provides an energy-saving control method for energy-saving windows, which includes the following steps:

[0021] Set temperature thresholds, rainfall thresholds, and wind speed thresholds in the microprocessor;

[0022] Solar photovoltaic modules store energy. Temperature sensors, rainfall sensors, wind direction sensors, and solar altitude angle sensors collect data and transmit the data to a microprocessor for analysis. Based on the analysis results, the microprocessor controls the opening and closing of a window. The process is as follows:

[0023] The microprocessor receives the temperature value output by the temperature sensor and the rotation signal output by the wind speed sensor, and calculates the ambient temperature based on the temperature value and the wind speed based on the rotation signal.

[0024] The microprocessor determines whether the ambient temperature exceeds a temperature threshold or the wind speed exceeds a wind speed threshold. If the ambient temperature exceeds the temperature threshold or the wind speed exceeds the wind speed threshold, the microprocessor controls the window to close. If the ambient temperature does not exceed the temperature threshold and the wind speed does not exceed the wind speed threshold, the microprocessor determines whether the rain sensor has collected data.

[0025] If the rain sensor does not collect data, the microprocessor determines whether it is a sunny or cloudy day by checking whether the solar photovoltaic modules are working. The specific process is as follows:

[0026] If the solar photovoltaic modules are working, it is determined to be a sunny day. The microprocessor controls the opening of the window and calculates the first flip angle β1 of the window based on the solar altitude angle.

[0027] If the solar photovoltaic modules are not working, it is determined to be a cloudy day. The microprocessor controls the opening of the window and calculates the second flip angle β2 of the window based on the wind direction.

[0028] If the rain sensor collects data, the microprocessor determines whether the rain sensor is collecting data incorrectly by checking whether the solar photovoltaic module is working. The specific process is as follows:

[0029] If the solar photovoltaic module is working, it is determined that the rain sensor has a false data collection. The microprocessor controls the opening of the window and calculates the second flip angle β2 of the window based on the wind direction angle.

[0030] If the solar photovoltaic module is not working, it is determined that the rain sensor has not mis-collected data. The microprocessor further determines whether the rainfall exceeds the rainfall threshold. If the rainfall exceeds the rainfall threshold, the microprocessor controls the window to close. If the rainfall does not exceed the rainfall threshold, the microprocessor controls the window to open and determines the direction of water droplet fall based on the wind direction and calculates the second flip angle β2 of the window.

[0031] The first flip angle β1 of the window is:

[0032] β1=sin -1 ((H×cosα1) / B)-α1;

[0033] In the formula, H represents the length of the window, B represents the width of the window, and α1 represents the solar altitude angle;

[0034] The second flip angle β2 of the form is:

[0035] β2=sin -1((H×cosα2) / B)-α2;

[0036] In the formula, H represents the length of the window, B represents the width of the window, and α2 represents the wind direction angle.

[0037] According to a third aspect of the embodiments of this application, this application also provides an intelligent building exterior wall, which includes the energy-saving windows described in any of the preceding claims.

[0038] According to the above specific embodiments of this application, at least the following beneficial effects are achieved: the energy-saving window provided by this application integrates solar photovoltaic modules into the hollow glass shell, and generates electricity using solar photovoltaic modules without affecting indoor lighting, thereby achieving green energy storage; the electricity stored by the solar photovoltaic modules can be used to supply indoor electrical equipment, thereby achieving the purpose of energy conservation and emission reduction.

[0039] The energy-saving window provided in this application, by incorporating a microprocessor, a drive unit, a rain sensor, a temperature sensor, a wind direction sensor, a solar altitude angle sensor, a first heat pipe, and a heat dissipation mechanism, can control the opening, closing, and tilting angle of the window based on indoor and outdoor environmental parameters. With the cooperation of the first heat pipe and the heat dissipation mechanism, it can control the direction of heat generated by the solar photovoltaic modules. Even when the window is closed, it can still achieve heat dissipation. Furthermore, based on the heat dissipation direction, in summer, heat is directed to the outside to prevent indoor temperature from rising, thereby reducing the energy consumption of indoor cooling equipment. In winter, heat is directed to the inside to raise the indoor temperature, thereby reducing the energy consumption of indoor heating equipment, further achieving the goal of energy conservation and emission reduction.

[0040] It should be understood that the above general description and the following specific embodiments are merely exemplary and illustrative, and do not limit the scope of the claims made in this application. Attached Figure Description

[0062] Certain terms used to describe this application will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the application.

[0063] like Figures 1-4 As shown, the energy-saving window provided in this application includes a window frame 1 and a window body 2. The window frame 1 is used to install on the exterior wall facade, and the window body 2 is installed on the window frame 1. The window body 2 can be opened or closed relative to the window frame 1.

[0064] Heat dissipation mechanisms 11 are installed inside both sides of the window frame 1 in the width direction.

[0065] Window 2 includes a double-glazed glass shell 21, within which a solar photovoltaic module 22 is installed. The solar photovoltaic module 22 has a transparent structure and stores energy on sunny days, enabling intelligent and green building without affecting indoor lighting.

[0066] Along the height direction of the insulating glass shell 21, two or more first heat conduction pipes 23 are provided at intervals on both sides of the width direction of the insulating glass shell 21. One end of the first heat conduction pipe 23 protrudes into the interior of the insulating glass shell 21, and the other end is used to communicate with the heat dissipation mechanism 11 when the window 2 is closed relative to the window frame 1.

[0067] The first heat pipe 23 works in conjunction with the heat dissipation mechanism 11 to dissipate the heat generated by the operation of the solar photovoltaic module 22 into the room or out to the outside.

[0068] The energy-saving window provided in this application integrates a solar photovoltaic module 22 into a hollow glass shell 21. Without affecting indoor lighting, the solar photovoltaic module 22 generates electricity, achieving green energy storage. The electricity stored in the solar photovoltaic module 22 can be used to power indoor electrical appliances, achieving energy conservation and emission reduction. Furthermore, the heat generated by the first heat pipe 23 and the heat dissipation mechanism 11 can be exhausted into the room or outdoors through the cooperation of the solar photovoltaic module 22, further achieving the goal of energy conservation and emission reduction.

[0069] In the above embodiments, such as Figure 2As shown, the window frame 1 has a mounting hole 12, and the window body 2 is set in the mounting hole 12.

[0070] In the above embodiment, the window frame 1 is equipped with a drive unit 3 and a microprocessor. For example... Figure 4 As shown, a rotating shaft 4 runs through the top of window 2 along its width, with both ends extending into the window frame 1. The rotating shaft 4 is fixedly connected to window 2 and rotatably connected to the window frame 1. The output end of the drive unit 3 is linked to the portion of the rotating shaft 4 located within the window frame 1 via a conveyor belt. The control end of the drive unit 3 is connected to a microprocessor. Both the drive unit 3 and the microprocessor are connected to a solar photovoltaic module 22, which supplies power to both. The microprocessor drives the rotating shaft 4 to rotate via the drive unit 3 and the conveyor belt, causing window 2 to rotate relative to the window frame 1, thus opening or closing window 2.

[0071] In the above embodiment, a rain sensor, a temperature sensor, a wind direction sensor 5, and a solar altitude angle sensor 6 are installed on the side of the window frame 1 closest to the outside. All of these sensors are connected to a microprocessor.

[0072] The rain sensor includes a raindrop collection device, a metering device, and a signal processor. The raindrop collection device is installed along the height of the window frame 1 and fixedly connected to it. Both the metering device and the signal processor are housed within the raindrop collection device, and both the solar photovoltaic module 22 and the metering device are connected to the signal processor. The solar photovoltaic module 22 powers the signal processor. Raindrops fall into the raindrop collection device and strike the metering device, generating a metering electrical signal which is transmitted to the signal processor. The signal processor analyzes the metering signal to obtain the number of raindrops. The signal processor then sends the number of raindrops to a microprocessor. The microprocessor calculates the rainfall amount based on the number of raindrops.

[0073] A temperature sensor is mounted on the top of window frame 1. It includes a thermistor and a signal converter. The thermistor is connected to the signal converter, which in turn is connected to a microprocessor. The thermistor's resistance changes with temperature. The signal converter converts the thermistor's resistance value into a temperature value and sends this value to the microprocessor. The microprocessor then determines the ambient temperature based on the temperature value.

[0074] like Figure 5As shown, the wind direction sensor 5 includes a first base 51, a first support tube 52, a second support tube 53, a wind vane 54, and a signal conversion circuit (not shown in the figure). The first base 51 is positioned along the height of the window frame 1. The first support tube 52 is coaxially rotatably connected to the first base 51 along its axial direction. The second support tube 53 is fixedly connected to the opposite end of the first support tube 52 from the end connected to the first base 51, in a direction perpendicular to the axial direction of the first base 51. The wind vane 54 is fixedly positioned at one end of the second support tube 53 along its length. The signal conversion circuit is located in the first support tube 52 and is connected to a solar photovoltaic module 22, which powers the signal conversion circuit. The signal conversion circuit is also connected to a microprocessor.

[0075] When the wind vane 54 rotates, the first support tube 52 and the signal conversion circuit rotate with the wind vane 54 via the second support tube 53. The signal conversion circuit converts the rotational motion of the wind vane 54 into a rotation signal and sends this signal to the microprocessor. The microprocessor obtains the wind direction angle and wind speed based on the rotation signal.

[0076] like Figure 6 As shown, the solar altitude angle sensor 6 includes a second base 61, a scale 62, and a pointer 63. The scale 62 is mounted on the second base 61, and a hemispherical groove 621 is formed on the scale 62, extending from its upper surface towards the second base 61; that is, the opening of the groove 621 is located on the upper surface of the scale 62. Two or more scale lines 622, which are strip-shaped photoresistors, are spaced apart on the concave surface of the groove 621. The photoresistors are connected to a microprocessor. The pointer 63 is positioned at the center of the bottom surface of the groove 621 and is perpendicular to the upper surface of the scale 62. The opening of the groove 621 is positioned along the height direction of the window frame 1.

[0077] When sunlight shines on pointer 63, pointer 63 projects a shadow onto the concave surface of scale groove 621, which blocks scale line 622. The resistance value of the photoresistor that is not exposed to sunlight will be low. The microprocessor calculates the solar altitude angle based on the resistance value of the photoresistor.

[0078] The microprocessor controls the opening, closing, and flipping angle of window 2 based on data detected by the rain sensor, temperature sensor, and wind direction sensor 5. The microprocessor has preset thresholds for rainfall, temperature, and wind speed. It compares the ambient temperature and wind speed with these thresholds to determine whether the ambient temperature exceeds the temperature threshold or the wind speed exceeds the wind speed threshold.

[0079] If the ambient temperature exceeds the temperature threshold or the wind speed exceeds the wind speed threshold, the microprocessor will close window 2.

[0080] If the ambient temperature does not exceed the temperature threshold and the wind speed does not exceed the wind speed threshold, the microprocessor determines whether the rain sensor has collected data.

[0081] If the rain sensor does not collect data, the microprocessor further determines whether it is a sunny or cloudy day by checking if the solar photovoltaic module 22 is working. If the solar photovoltaic module 22 is working, it is determined to be a sunny day, and the microprocessor controls the opening of the window and calculates the first flip angle β1 of the window 2 based on the solar altitude angle; if the solar photovoltaic module 22 is not working, it is determined to be a cloudy day, and the microprocessor controls the opening of the window and calculates the second flip angle β2 of the window 2 based on the wind direction angle.

[0082] If the rain sensor collects data, the microprocessor further determines whether the rain sensor has miscollected data by checking whether the solar photovoltaic module 22 is working. The specific process is as follows:

[0083] If the solar photovoltaic module 22 is working, it is determined that the rain sensor has mis-collected data. The microprocessor controls the opening of the window and calculates the second flip angle β2 of the window 2 based on the wind direction angle.

[0084] If the solar photovoltaic module 22 is not working, it is determined that the rain sensor has not mis-collected any data. The microprocessor further determines whether the rainfall exceeds the rainfall threshold. If the rainfall exceeds the rainfall threshold, the microprocessor controls the window 2 to close. If the rainfall does not exceed the rainfall threshold, the microprocessor controls the window to open and determines the direction of water droplet fall based on the wind direction and calculates the second flip angle β2 of the window 2.

[0085] Wherein, the first flip angle β1 of form 2 is:

[0086] β1=sin -1 ((H×cosα1) / B)-α1;

[0087] In the formula, H represents the length of window 2, B represents the width of window 2, and α1 represents the solar altitude angle. The second flip angle β2 of window 2 is:

[0088] β2=sin -1 ((H×cosα2) / B)-α2;

[0089] In the formula, H represents the length of window 2, B represents the width of window 2, and α2 represents the wind direction angle.

[0090] In the above embodiments, such as Figure 2 and Figure 3As shown, the heat dissipation mechanism 11 includes a second heat-conducting pipe 111, a third heat-conducting pipe 112, an elastic element 113, and an opening / closing assembly 114. The second heat-conducting pipe 111 is installed inside both sides of the window frame 1 in the width direction of the window frame 1, along the height direction of the second heat-conducting pipe 111. Two or more third heat-conducting pipes 112 are spaced apart on the side of the second heat-conducting pipe 111 closest to the mounting hole 12. One end of each third heat-conducting pipe 112 communicates with the body of the second heat-conducting pipe 111, and the other end communicates with the corresponding first heat-conducting pipe 23 when the window 2 is closed relative to the window frame 1.

[0091] Both ends of the second heat pipe 111 are connected to an opening and closing assembly 114 via an elastic element 113. The opening and closing assembly 114 includes a connecting rod 1141, a first baffle 1142, and a second baffle 1143. The connecting rod 1141 has a T-shaped structure. The opposite ends of the vertical and horizontal rods in the T-shaped structure are connected to the elastic element 113. One end of the horizontal rod in the T-shaped structure is connected to one end of the first baffle 1142. Along the height direction of the second heat pipe 111, the other end of the first baffle 1142 extends away from the elastic element 113. The other end of the horizontal rod in the T-shaped structure is connected to one end of the second baffle 1143. Along the height direction of the second heat pipe 111, the other end of the second baffle 1143 extends towards the elastic element 113.

[0092] It is understandable that one end of the crossbar in the T-shaped structure is connected to one end of the first baffle 1142, and the other end of the first baffle 1142 can also extend towards the elastic member 113 along the height direction of the second heat pipe 111; the other end of the crossbar in the T-shaped structure is connected to one end of the second baffle 1143, and the other end of the second baffle 1143 can also extend away from the elastic member 113 along the height direction of the second heat pipe 111.

[0093] In other words, the first baffle 1142 and the second baffle 1143 are misaligned, so that the first baffle 1142, the crossbar in the T-shaped structure and the second baffle 1143 form a Z-shaped structure.

[0094] First heat dissipation holes 13 are provided at the top and bottom of the side wall near the outside in the thickness direction of the window frame 1, and second heat dissipation holes 14 are provided at the top and bottom of the side wall near the inside in the thickness direction of the window frame 1. The center line perpendicular to the plane containing the first heat dissipation hole 13 can be on the same straight line as the center line perpendicular to the plane containing the second heat dissipation hole 14. A first baffle 1142 is disposed opposite to the first heat dissipation hole 13 and is used to close the first heat dissipation hole 13. A second baffle 1143 is disposed opposite to the second heat dissipation hole 14 and is used to close the second heat dissipation hole 14.

[0095] When the indoor temperature is higher than the outdoor temperature, the elastic element 113 is in its initial state, the first baffle 1142 is located at the first heat dissipation hole 13 and is used to close the first heat dissipation hole 13; the second baffle 1143 is located at one end of the second heat dissipation hole 14 along the height direction of the second heat pipe 111 and does not close the second heat dissipation hole 14.

[0096] In this embodiment, an insulation layer is adhered to the outer wall of both the second heat pipe 111 and the third heat pipe 112. By providing the insulation layer, heat can be concentrated in the second heat pipe 111 and the third heat pipe 112, allowing heat to be dissipated along a predetermined path.

[0097] In this embodiment, the first baffle 1142 is slidably connected to the side wall near the outside in the thickness direction of the window frame 1, and the second baffle 1143 is slidably connected to the side wall near the inside in the thickness direction of the window frame 1.

[0098] Specifically, a first groove is formed on the inner surface of the exterior sidewall of the window frame 1 in the thickness direction. A first slider is provided on the side of the first baffle 1142 opposite to the exterior sidewall of the window frame 1 in the thickness direction. The first baffle 1142 is slidably connected to the exterior sidewall of the window frame 1 in the thickness direction via the first slider and the first groove. A second groove is formed on the inner surface of the interior sidewall of the window frame 1 in the thickness direction. A second slider is provided on the side of the second baffle 1143 opposite to the interior sidewall of the window frame 1 in the thickness direction. The second baffle 1143 is slidably connected to the interior sidewall of the window frame 1 in the thickness direction via the second slider and the second groove.

[0099] The first baffle 1142 is limited along the height direction of the window frame 1 by the first slide groove and the first slider, and the second baffle 1143 is limited along the height direction of the window frame 1 by the second slide groove and the second slider, thereby improving the stability of the opening and closing assembly 114.

[0100] In this embodiment, specifically, the elastic element 113 can be a contraction spring or a tension spring.

[0101] When the elastic element 113 is a contraction-type spring, in its initial state, the first baffle 1142 is located on the side of the first heat dissipation hole 13 closer to the elastic element 113, and the second baffle 1143 is located on the side of the second heat dissipation hole 14 away from the elastic element 113. The initial positions of the first baffle 1142 and the second baffle 1143 are set according to the contraction performance of the contraction-type spring, so that the first baffle 1142 and the second baffle 1143 can slide with the deformation of the contraction-type spring to open the first heat dissipation hole 13 and close the second heat dissipation hole 14.

[0102] When the elastic element 113 is a tension spring, in its initial state, the first baffle 1142 is located on the side of the first heat dissipation hole 13 away from the elastic element 113, and the second baffle 1143 is located on the side of the second heat dissipation hole 14 close to the elastic element 113. The initial positions of the first baffle 1142 and the second baffle 1143 are set according to the tensile properties of the tension spring, so that the first baffle 1142 and the second baffle 1143 can slide with the deformation of the tension spring to open the first heat dissipation hole 13 and close the second heat dissipation hole 14.

[0103] In the above embodiments, such as Figure 2 As shown, one or more drainage holes 15 are provided at the bottom of the window frame 1, and a drainage baffle is hinged to the drainage hole 15.

[0104] When rainwater enters the window frame 1 through the first heat dissipation hole 13 during rainy weather, it can be drained through the drainage hole 15. The drainage baffle is closed when there is no rain to prevent it from affecting the heat dissipation and heat preservation effect. When rainwater accumulates at the bottom of the window frame 1, the drainage baffle opens under the action of gravity, and the rainwater drains through the drainage hole 15 to prevent rainwater from accumulating inside the window frame 1 and seeping into the room.

[0105] In the above embodiments, sound-absorbing cotton is adhered to the side wall inside the window frame 1 near the interior. The sound-absorbing cotton can reduce the noise generated by the operation of the drive unit 3.

[0106] The specific working process of the energy-saving window provided in this application is as follows:

[0107] When the solar photovoltaic module 22 is working, it generates heat, causing an increase in air pressure inside the hollow glass shell 21. The first heat pipe 23 absorbs the heat inside the hollow glass shell 21. If the window 2 is not closed, the heat is discharged through the first heat pipe 23, which can avoid affecting the operation of the solar photovoltaic module 22. If the window 2 is closed, the heat is transferred along the first heat pipe 23 and the third heat pipe 112 to the second heat pipe 111, and the heat from the second heat pipe 111 is released near the elastic element 113.

[0108] In summer, due to the use of air conditioning, the indoor temperature is lower than the outdoor temperature. The solar photovoltaic module 22 generates a significant amount of heat during operation. While absorbing the heat generated by the solar photovoltaic module 22, the first heat pipe 23 also absorbs some outdoor heat. Under this high heat, the elastic element 113 deforms, driving the connecting rod 1141 to move closer to the center of the third conduit, thereby causing the second baffle 1143 to close the second heat dissipation hole 14. Because the first baffle 1142 and the second baffle 1143 are staggered, when the second baffle 1143 closes the second heat dissipation hole 14, the first baffle 1142 opens the first heat dissipation hole 13, releasing the heat near the elastic element 113 to the outside through the first heat dissipation hole 13, thus reducing the energy consumption of the indoor cooling equipment.

[0109] In winter, due to the heating or air conditioning being on, the indoor temperature is higher than the outdoor temperature. The elastic element 113 is in its initial state, the first baffle 1142 closes the first heat dissipation hole 13, and the second baffle 1143 does not close the second heat dissipation hole 14. At this time, the heat generated by the solar photovoltaic module 22 is insufficient to cause the elastic element 113 to deform. The heat generated by the solar photovoltaic module 22 enters the room through the second heat dissipation hole 14, which can increase the indoor temperature and thus reduce the energy consumption of the indoor heating equipment.

[0110] The energy-saving window provided in this application, by incorporating a microprocessor, a driver 3, a rain sensor, a temperature sensor, a wind direction sensor 5, a solar altitude angle sensor 6, a first heat pipe 23, and a heat dissipation mechanism 11, can control the opening and closing of the window 2 based on indoor and outdoor environmental parameters. With the cooperation of the first heat pipe 23 and the heat dissipation mechanism 11, the direction of heat generated by the solar photovoltaic module 22 can be controlled. Even when the window 2 is closed, heat dissipation is still achieved. Furthermore, based on the heat dissipation direction of the window 2, heat is directed outdoors in summer to prevent indoor temperature rise and reduce the energy consumption of indoor cooling equipment. In winter, heat is directed indoors to increase indoor temperature and reduce the energy consumption of indoor heating equipment, further achieving the goal of energy conservation and emission reduction.

[0111] Specifically, this application uses sensors to collect data on changes in the outdoor environment. A microprocessor analyzes the data collected by the sensors to control the opening and closing of window 2 and its rotation angle, thereby improving living comfort and safety. When the ambient temperature exceeds a temperature threshold, the indoor temperature control device will be activated; closing window 2 reduces the energy consumption of the temperature control device. When rainfall exceeds a rainfall threshold or wind speed exceeds a wind speed threshold, the microprocessor controls the closing of window 2 to prevent rainwater from entering the room or to prevent safety risks caused by excessive wind. When the data from the rainfall sensor is abnormal, the working status of the solar photovoltaic module 22 is considered to determine whether there is false data collection. This eliminates the possibility of water droplets falling on the window frame 1 due to outdoor cleaning or construction work, thus improving the accuracy of energy-saving window control.

[0112] Based on the energy-saving window provided in this application, this application also provides an energy-saving control method, which includes the following steps:

[0113] S1. Set the temperature threshold, rainfall threshold, and wind speed threshold in the microprocessor.

[0114] S2, such as Figure 7 As shown, the solar photovoltaic module 22 stores energy. Temperature sensors, rainfall sensors, wind direction sensors, and solar altitude angle sensors collect data and transmit the collected data to the microprocessor for judgment. Based on the judgment result, the microprocessor controls the opening and closing of window 2. The process is as follows:

[0115] S21. The microprocessor receives the temperature value output by the temperature sensor and the rotation signal output by the wind speed sensor, and calculates the ambient temperature based on the temperature value and the wind speed based on the rotation signal.

[0116] S22. The microprocessor determines whether the ambient temperature exceeds the temperature threshold or the wind speed exceeds the wind speed threshold. If the ambient temperature exceeds the temperature threshold or the wind speed exceeds the wind speed threshold, the microprocessor controls the window to close. If the ambient temperature does not exceed the temperature threshold and the wind speed does not exceed the wind speed threshold, proceed to step S23.

[0117] S23. The microprocessor determines whether the rain sensor has collected data.

[0118] If the rain sensor does not collect data, proceed to step S24.

[0119] If the rain sensor has collected data, proceed to step S25.

[0120] S24. The microprocessor determines whether it is a sunny or cloudy day by judging whether the solar photovoltaic module 22 is working. The specific process is as follows:

[0121] If the solar photovoltaic module 22 is working, it is determined to be a sunny day. The microprocessor controls the opening of window 2 and calculates the first flip angle β1 of window 2 according to the solar altitude angle, and then controls window 2 to open according to the first flip angle β1.

[0122] If the solar photovoltaic module 22 is not working, it is determined to be a cloudy day. The microprocessor controls the opening of window 2 and calculates the second flip angle β2 of window 2 according to the wind direction angle, and then controls window 2 to open according to the second flip angle β2.

[0123] S25. The microprocessor determines whether the rain sensor is erroneously collecting data by checking whether the solar photovoltaic module 22 is working. The specific process is as follows:

[0124] If the solar photovoltaic module 22 is working, it is determined that the rain sensor has a false data collection. The microprocessor controls the opening of window 2 and calculates the second flip angle β2 of window 2 according to the wind direction angle, and then controls window 2 to open according to the second flip angle β2.

[0125] If the solar photovoltaic module 22 is not working, it is determined that the rain sensor has not mis-collected any data. The microprocessor further determines whether the rainfall exceeds the rainfall threshold. If the rainfall exceeds the rainfall threshold, the microprocessor controls the window 2 to close. If the rainfall does not exceed the rainfall threshold, the microprocessor controls the window 2 to open, determines the direction of water droplet fall based on the wind direction, calculates the second flip angle β2 of the window 2, and then controls the window 2 to open according to the second flip angle β2.

[0126] In step S3 above, the first flip angle β1 of form 2 is:

[0127] β1=sin -1 ((H×cosα1) / B)-α1;

[0128] In the formula, H represents the length of window 2, B represents the width of window 2, and α1 represents the solar altitude angle. The second flip angle β2 of window 2 is:

[0129] β2=sin -1 ((H×cosα2) / B)-α2;

[0130] In the formula, H represents the length of window 2, B represents the width of window 2, and α2 represents the wind direction angle.

[0131] This application also provides an intelligent building facade that includes the aforementioned energy-saving windows.
