Description

Technical Field

[0001] The invention relates to the technical field of indoor temperature regulating equipment, in particular to a solar intelligent temperature regulating and energy-saving device and a preparation method thereof. Background Art

[0002] As living standards improve, people tend to set up temperature control equipment indoors to ensure a comfortable indoor temperature. Air conditioners, as indoor temperature control equipment, are widely used in homes, factories, servers, and other places. However, air conditioners usually require a large amount of electricity supply, especially in high temperature or extremely cold climate conditions. Continuous use of air conditioners consumes a lot of electricity, which not only puts pressure on energy supply, but also increases energy expenses to a certain extent.

[0003] There are also some materials on the market that adjust the emissivity according to the ambient temperature, such as temperature-adaptive radiation coatings. Such coatings are installed on the roof to achieve the effect of temperature regulation. However, the phase change temperature range of materials that adjust the emissivity according to the ambient temperature is limited and is usually only effective within a specific temperature range. Moreover, when the solar radiation is low, this material can only change its emissivity, and its low absorption rate performance cannot be changed, and it cannot absorb more heat, and its ability to regulate indoor temperature is limited. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a solar intelligent temperature regulating and energy-saving device and a preparation method thereof.

[0005] The solution of the present invention to solve its technical problem is:

[0006] A solar intelligent temperature regulating and energy-saving device, comprising:

[0007] A support frame, wherein the support frame is made of a transparent material, the support frame is hollow to form an absorption cavity, the absorption cavity is provided with a first mounting portion and a second mounting portion, and the first mounting portion is provided on the upper side of the second mounting portion;

[0008] A lens component, wherein the lens component is disposed in the absorption cavity and connected to the first mounting portion, and an upper surface of the lens component protrudes upward;

[0009] An absorption base is arranged in the absorption cavity and connected to the second mounting portion. The absorption base is provided with a first absorption area and a second absorption area. The first absorption area is arranged on the front side of the second absorption area. A first absorption layer is provided on the surface of the first absorption area. A second absorption layer is provided on the surface of the second absorption area. The absorption rate of the first absorption layer is greater than the absorption rate of the second absorption layer.

[0010] The present invention has at least the following beneficial effects: the support frame is used to provide an installation position for the lens component and the absorption base, and to provide support for the lens component and the absorption base, so that the lens component and the absorption base can be stably placed and intelligently temperature controlled; the lens component is arranged above the absorption base, and the absorption base is provided with a first absorption area and a second absorption area with different absorptivity, after the sunlight passes through the lens component, it converges to the first absorption area or the second absorption area of ​​the absorption base, so as to realize the effective separation of the radiation areas of the solar radiation intensity, and respectively adjust the temperature of the sunlight converged in different areas, so as to realize the intelligent temperature control and energy saving effect in a zero energy consumption manner; in winter, the sunlight converges in the first absorption area, the first absorption area has a high absorptivity and a low reflectivity, which can enhance the absorption of heat, thereby increasing the indoor temperature; in summer, the sunlight converges in the second absorption area, the second absorption area has a low absorptivity and a high reflectivity, which can reduce the absorption of heat, thereby achieving the effect of lowering the indoor temperature.

[0011] As a further improvement of the above technical solution, the absorption base includes a plurality of absorption steps, which are arranged in the left-right direction, and the height of the absorption steps decreases from the left and right sides to the middle. The plurality of absorption steps can ensure that sunlight can be concentrated on the absorption base in all time periods, and prevent the light spot formed by sunlight passing through the lens component from being too large or overflowing the absorption base.

[0012] As a further improvement of the above technical solution, the left side or right side of the support frame is opened, and the lens component and the absorption base are detachably connected to the absorption chamber. In this way, the lens component and the absorption base can be removed or installed from the opening position of the support frame, which is beneficial to the processing of each component and also to the subsequent maintenance of each component.

[0013] As a further improvement of the above technical solution, the support frames are provided in plurality, each of which is respectively provided with a lens component and an absorption base, and the plurality of support frames are arranged in a matrix, and two adjacent support frames are detachably connected. Such an arrangement can increase the absorption range area of ​​the solar intelligent temperature control and energy saving device and improve the efficiency of temperature control.

[0014] As a further improvement of the above technical solution, the absorptivity of the first absorption layer ranges from 0.90 to 0.95, and the reflectivity of the second absorption layer ranges from 0.90 to 0.98. The first absorption layer within the absorptivity range can effectively absorb the heat of sunlight, allowing the indoor temperature of the solar intelligent temperature control and energy-saving device to rise quickly, achieving a warming effect; while the second absorption layer within the reflectivity range can effectively reflect sunlight, reduce the indoor temperature, and make the indoor environment more comfortable.

[0015] A method for preparing a solar intelligent temperature regulating and energy-saving device, which is used to prepare a solar intelligent temperature regulating and energy-saving device as described in any one of the above technical solutions, comprises the following steps:

[0016] Determine the dimensions of the support frame, lens assembly, and absorbent base;

[0017] preparing the support frame;

[0018] preparing the lens component;

[0019] preparing the absorption base;

[0020] The support frame, the lens assembly and the absorbent base are assembled and positioned.

[0021] First determine the dimensions of the support frame, lens component and absorption base, and then prepare them separately, which can ensure the compatibility of the connection and assembly between the support frame, lens component and absorption base. After installation, the lens component and the absorption base can be stabilized on the support frame and the temperature can be intelligently adjusted. The assembled solar energy intelligent temperature control and energy-saving device can achieve the effect of intelligent temperature control and energy saving in a zero-energy consumption manner.

[0022] As a further improvement of the above technical solution, the steps of preparing the lens component include the following steps:

[0023] Determining the material of the lens component;

[0024] cutting the lens component according to required size;

[0025] An anti-reflection film is coated on the surface of the lens component.

[0026] After selecting the materials, the lens components are cut and the obtained lens components can be installed in the supporting frame and can focus sunlight. Coating an anti-reflection film on the surface of the lens components can improve the light transmittance of the lens components and effectively reduce reflection during oblique incidence at the winter solstice, thereby improving the light utilization rate of the solar intelligent temperature control and energy-saving device.

[0027] As a further improvement of the above technical solution, the step of preparing the absorption base includes the following steps:

[0028] Determining the material for preparing the absorption base;

[0029] The absorption base is designed to form a plurality of absorption steps;

[0030] A first absorption layer and a second absorption layer are coated on the surface of the absorption base.

[0031] By manufacturing the absorption base in the above manner, sunlight of different radiation intensities can be effectively converged to positions with different absorption rates, thereby achieving the effect of zoned regulation. Moreover, the absorption base is designed as multiple absorption steps, so that the light spot formed by the convergence of sunlight on the absorption base can be of an appropriate size and kept within the range of regulated absorption.

[0032] As a further improvement of the above technical solution, the steps of assembling and placing the support frame, the lens component and the absorption base include the following steps:

[0033] Mounting the lens component to the first mounting portion of the support frame;

[0034] mounting the absorption base to the second mounting portion of the support frame;

[0035] The support frame is placed tilted according to the actual geographical location.

[0036] After installing the lens components and the absorption base to the corresponding positions of the support frame, the placement angle of the support frame is adjusted to improve the utilization rate of sunlight, so that the light spot falls on the absorption base at a more appropriate position, avoiding the overflow of the light spot, which is more conducive to temperature control.

[0037] As a further improvement of the above technical solution, the inclination angle of the support frame is the latitude of the placement position. The support frame is placed in an inclined manner according to the actual geographical location, so that the light spot formed by the sunlight passing through the lens component can fall into the appropriate position of the absorption base, and the convergent light spot of the sunlight on the winter solstice and the summer solstice falls symmetrically on the front and rear sides of the central axis of the absorption base, which is more conducive to temperature control.

[0054] Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0055] Reference Figures 1 to 3 The embodiment of the present invention provides a solar energy intelligent temperature control and energy saving device, which can achieve the effect of intelligent temperature control and energy saving in a zero energy consumption manner.

[0056] In this embodiment, the solar intelligent temperature control and energy saving device includes a support frame 600, a lens component 700 and an absorption base 800. The support frame 600 provides a fixed installation position for the lens component 700 and the absorption base 800, and the hollow space forms an absorption cavity, and the absorption cavity is provided with two installation positions, namely, a first installation portion 610 and a second installation portion 620. The first installation portion 610 is arranged above the second installation portion 620 for installing the lens component 700; the second installation portion 620 is arranged at the bottom of the absorption cavity for installing the absorption base 800.

[0057] In this embodiment, the lens component 700 is entirely located in the absorption cavity, and the lens component 700 is a convex lens, whose upper surface is convex upward, and can converge sunlight. The sunlight converged by the lens component 700 forms a light spot on the absorption base 800 and is absorbed by the absorption base 800.

[0058] The absorption base 800 is disposed as a whole inside the absorption cavity, and is provided with a first absorption zone 810 and a second absorption zone 820. The second absorption zone 820 is disposed on the rear side of the first absorption zone 810. Sunlight can form a light spot in the first absorption zone 810 or the second absorption zone 820 and be absorbed.

[0059] In this embodiment, a first absorption layer is disposed on the surface of the first absorption zone 810, and a second absorption layer is disposed on the surface of the second absorption zone 820. The first absorption layer has a high absorption rate, and the second absorption layer has a high reflectivity, that is, the absorption rate of the first absorption layer is greater than the absorption rate of the second absorption layer.

[0060] In this embodiment, the absorptivity of the first absorption layer ranges from 0.90 to 0.95, and the reflectivity of the second absorption layer ranges from 0.90 to 0.98. In some embodiments, the first absorption layer is a black paint material, and the second absorption layer is an aluminum sheet material.

[0061] It can be understood that this embodiment focuses sunlight of different radiation intensities into areas with different absorption rates based on the lens component 700. The first absorption area 810 is a weak solar irradiation area located on the north side, while the second absorption area 820 is a strong solar irradiation area located on the south side.

[0062] In winter, sunlight is concentrated in the first absorption area 810. The first absorption area 810 has a high absorption rate and a low reflectivity for sunlight. Most of the sunlight is absorbed into the room, which enhances the absorption of heat and thus can increase the indoor temperature.

[0063] In summer, sunlight is concentrated in the second absorption area 820. The second absorption area 820 has a low absorption rate for sunlight and a high reflectivity, which can reduce the absorption of heat, thereby achieving the effect of lowering the indoor temperature.

[0064] The solar energy intelligent temperature control and energy saving device of this embodiment utilizes the optical property of the lens component 700 to focus the light spot at different positions at different incident angles, thereby realizing the effective separation of radiation areas with different solar radiation intensities, and adjusting the absorption rate in each area by zoning, thereby realizing intelligent temperature control and energy saving in a zero-energy consumption manner, achieving the effect of warmth in winter and coolness in summer.

[0065] In this embodiment, the support frame 600 is made of transparent materials such as PMMA, and the size of the support frame 600 is determined according to the size of the reserved position where the solar intelligent temperature control and energy saving device of this embodiment needs to be installed. In this embodiment, the total height of the support frame 600 is designed to be 15 cm, and the length and width of the absorption cavity are both 11 cm.

[0066] In this embodiment, the lens component 700 is made of BK7 material. In this embodiment, the height of the lens component 700 is 2.2 cm and the radius of curvature is 8.3 cm.

[0067] In this embodiment, in order to ensure that the solar light spot is within the control range of the absorption base 800, the absorption base 800 is designed to have multiple absorption steps, which are arranged in the left-right direction, and the height of the absorption steps decreases from the left and right sides to the middle, that is, the height of the absorption step in the middle is the shortest, and the height of the absorption step at the left and right ends is the highest. In different time periods, the light spot converges on different absorption steps.

[0068] In this embodiment, there are five absorption steps. The two absorption steps at the left and right ends are 11 cm long, 2.1 cm wide, and 5 cm high. The absorption step in the middle is 11 cm long, 2.6 cm wide, and 0.2 cm high. The remaining two absorption steps are 11 cm long, 2.1 cm wide, and 1.5 cm high.

[0069] It is understandable that, in this arrangement, different absorption steps are used to absorb light spots at different times. In this embodiment, the absorption steps from left to right are used to absorb light spots at 10 o'clock, 11 o'clock, 12 o'clock, 13 o'clock and 14 o'clock in sequence.

[0070] It is understandable that the height of the absorption step can be adjusted according to the curvature radius of the lens component 700, and the height of the absorption step cannot be too high or too low, so that the size and position of the light spot are appropriately distributed on the absorption area of ​​the absorption step. If the height of the absorption step is too high, the distance between the upper surface of the absorption step and the lens component 700 is too small, and the light spot where the sunlight converges is too large, which is not conducive to zoning the light spot. If the height of the absorption step is too low, the distance between the upper surface of the absorption step and the lens component 700 is too large, and the light spot will overflow the range of the absorption step used to regulate absorption.

[0071] In order to ensure the utilization rate of sunlight, the support frame 600 is tilted when in use, and its tilt angle is the latitude of the actual placement position. Taking Beijing as an example, Beijing is located at 40 degrees north latitude, the front of the solar intelligent temperature control and energy saving device is located on the south side, and the rear is located on the north side. The support frame 600 is tilted toward the south, that is, the upper surface of the support frame 600 is tilted downward from the back to the front, and the tilt angle is 40 degrees.

[0072] In some embodiments, the lens component 700 is detachably connected to the inner wall of the absorption chamber, and the absorption base 800 is also detachably connected to the inner wall of the absorption chamber. It is understandable that the left side or right side of the support frame 600 is open, and the user can remove the lens component 700 and the absorption base 800 located in the absorption chamber through the opening position of the left side or right side of the support frame 600, or install the lens component 700 and the absorption base 800 into the absorption chamber from the opening position.

[0073] In some embodiments, a support member for supporting the lens component 700 is provided at the bottom of the first mounting portion 610, the support member is connected to the front and rear side walls of the absorption chamber, the lens component 700 is installed on the support member, and can be pulled out of the absorption chamber to the left or right. A support plate for supporting the absorption base 800 is provided at the bottom of the second mounting portion 620, the support plate is connected to the bottom surface of the absorption chamber, the absorption base 800 is slidably connected to the upper surface of the support plate, and the absorption base 800 can be pulled out of the absorption chamber to the left or right.

[0074] In other embodiments, a groove is provided at the bottom of the first mounting portion 610, the groove extends in the left-right direction and is provided at the front and rear walls of the absorption chamber and is open to the left or right, and the lens component 700 is provided with a protrusion corresponding to the groove, and the protrusion is slidably connected to the groove to achieve a detachable connection between the lens component 700 and the first mounting portion 610. A groove is provided at the bottom of the second mounting portion 620, the groove extends in the left-right direction and is open to the left or right, and the absorption base 800 is provided with a protrusion corresponding to the groove, and the protrusion is slidably connected to the groove, so that a detachable connection between the absorption base 800 and the second mounting portion 620 can be achieved.

[0075] It is understandable that since the lens component 700 and the absorption base 800 can be removed from the support frame 600 and connected by assembly, it is more conducive to the production of the lens component 700, the absorption base 800 and the support frame 600, and is also conducive to the subsequent maintenance of the lens component 700 and the absorption base 800. Moreover, by assembling the support frame 600, the lens component 700 and the absorption base 800 through the above embodiment, the structure is simple and the assembly is convenient.

[0076] In some embodiments, a plurality of support frames 600 are provided, and the plurality of support frames 600 are arranged in a matrix, and each support frame 600 is respectively provided with a lens component 700 and an absorption base 800. Such an arrangement can expand the adjustment area of ​​the solar intelligent temperature adjustment and energy saving device and improve the efficiency of temperature adjustment. In this embodiment, the solar intelligent temperature adjustment and energy saving device is provided with 10×10 support frames 600.

[0077] In some embodiments, two adjacent support frames 600 are detachably connected, and the user can change the number of support frames 600 according to actual conditions. It is understandable that two adjacent support frames 600 can be connected by connecting members such as hinges and buckles.

[0078] On the other hand, the embodiment of the present invention also proposes a method for preparing a solar intelligent temperature control and energy saving device, which is used to prepare a solar intelligent temperature control and energy saving device as proposed in any of the above embodiments. Specifically comprising steps S100, S200, S300, S400 and S500, refer to Figure 4 .

[0079] Step S100, determining the sizes of the support frame 600, the lens component 700 and the absorption base 800. It is understandable that the sizes of the support frame 600, the lens component 700 and the absorption base 800 need to be determined according to the actual needs of the user, and the reserved installation position needs to be measured, and the size of the support frame 600 is determined according to the measured size, and then the size of the lens component 700 and the size of the absorption base 800 are determined according to the size of the support frame 600 and the material thickness and other data.

[0080] It is understandable that step S100 can use drawing tools such as solid work to assist in the design, obtain the design drawings of the support frame 600, the lens component 700 and the absorption base 800, ensure that the dimensions of the lens component 700 and the absorption base 800 match the installation position of the support frame 600, thereby ensuring the adaptability and stability of the subsequent assembly.

[0081] Step S200 , preparing a support frame 600 . The support frame 600 is made of transparent low-absorption materials such as PMMA, and the formed support frame 600 has an absorption cavity for mounting the lens component 700 and the absorption base 800 .

[0082] Step S300, preparing the lens component 700. This step can obtain a convex lens with an upper surface convex upward, which is used to collect sunlight. In this embodiment, step S300 includes steps S310, S320 and S330. Figure 5 .

[0083] Step S310, determining the material for preparing the lens component 700. The lens component 700 is made of BK7 material, which has good light transmission performance.

[0084] Step S320, cutting the lens component 700 according to the required size. In this embodiment, according to the size of the support frame 600, the curvature radius of the lens component 700 is designed to be 8.3 cm and the height is 2.2 cm. At this time, the bottom diameter of the lens component 700 is 11 cm, which matches the size of the absorption chamber.

[0085] It can be understood that when the material is determined, the larger the radius of curvature of the lens component 700, the greater the focal length; when the radius of curvature is determined, the smaller the height of the lens component 700, the smaller the aperture, and the smaller the corresponding controllable area of ​​the absorption base 800. Therefore, the size of the lens component 700 can be optimized according to different requirements.

[0086] Step S330, coating the surface of the lens component 700 with an anti-reflection film. When sunlight is incident at different times, the reflectivity of the surface of the lens component 700 is related to the incident angle. The lower the altitude angle, the greater the reflectivity. By coating the surface of the lens component 700 with an anti-reflection film, the transmittance can be improved, and the reflection at oblique incidence during the winter solstice can be effectively reduced, thereby improving the light utilization rate of the solar intelligent temperature control and energy-saving device.

[0087] Step S400, preparing an absorption base 800. The absorption base 800 is used to absorb the solar spot in different areas to adjust the absorption effect of sunlight in different seasons, so as to achieve intelligent temperature control and energy saving in a zero-energy consumption manner, and achieve the effect of warm in winter and cool in summer.

[0088] In this embodiment, step S400 includes step S410, step S420 and step S430. Figure 6 .

[0089] Step S410, determining the material for preparing the absorption base 800. The material for preparing the absorption base 800 is a transparent low-absorption material such as PMMA.

[0090] Step S420, design the absorption base 800 to form a plurality of absorption steps. When the incident angle changes, since the focal length of the lens component 700 changes with the incident angle, in order to be able to receive light spots formed by different oblique incident angles, absorption steps of different heights and widths need to be designed.

[0091] It is understandable that if the height of the absorption step is too high, the distance between the upper surface of the absorption step and the lens component 700 is too small, and the spot where the sunlight converges is too large, which is not conducive to zoning the spot. If the height of the absorption step is too low, the distance between the upper surface of the absorption step and the lens component 700 is too large, and the spot will overflow the range of the absorption step used to regulate absorption.

[0092] Step S430: coating a first absorption layer and a second absorption layer on the surface of the absorption base 800. The first absorption layer and the second absorption layer are absorption materials with different absorption rates, wherein the absorption rate of the first absorption layer is greater than that of the second absorption layer.

[0093] It can be understood that the surface of the absorption base 800 is covered with materials with different absorption rates, and the optical property of the lens component 700 that the focus spot positions are different at different incident angles is utilized to achieve effective separation of radiation areas with different solar radiation intensities. Among them, the first absorption area 810 is an area with low solar radiation irradiation, and the first absorption layer is a high absorption material layer, such as a black paint sheet, with an absorption rate of 0.90-0.95. The second absorption area 820 is an area with high solar radiation irradiation, and the second absorption layer is a low absorption and high reflection material, such as an aluminum sheet, etc., with a reflectivity range of 0.90-0.98.

[0094] It is understandable that the specific division of the first absorption zone 810 and the second absorption zone 820 can be determined according to the solar radiation intensity and ambient temperature of the area where the solar intelligent temperature control and energy saving device of this embodiment is installed. In areas where the solar radiation intensity is low at noon and the ambient temperature is continuously below 20°C, that is, the ambient temperature T is less than 20°C, the sunlight is converged to the first absorption zone 810 through the lens component 700 to maximize the absorption of solar heat for heating. In the case of high solar radiation intensity, the sunlight is converged to the second absorption zone 820 to reduce heat absorption, thereby adjusting the temperature.

[0095] The ambient temperature varies greatly in different regions. Taking Beijing, Shanghai and Shenzhen as examples, according to the temperature distribution statistics at noon in Beijing, Shanghai and Shenzhen throughout the year, it can be observed that the temperature in Beijing is continuously below 20°C from early October to the end of March. Therefore, when the solar intelligent temperature control and energy-saving device of this embodiment is applied in Beijing, the position of the center of the light spot in early October can be used as the boundary between the first absorption zone 810 and the second absorption zone 820. But this does not apply to Shanghai and Shenzhen. When using the solar intelligent temperature control and energy-saving device of this embodiment in Shanghai and Shenzhen, it is necessary to set the boundary between the first absorption zone 810 and the second absorption zone 820 to the position of the center of the light spot in early November according to the temperature characteristics of Shanghai; and set the boundary between the first absorption zone 810 and the second absorption zone 820 to the position of the center of the light spot in early December according to the temperature characteristics of Shenzhen.

[0096] Step S500, assembling the support frame 600, the lens component 700 and the absorption base 800. In this embodiment, step S500 specifically includes step S510, step S520 and step S530. Figure 7 .

[0097] Step S510, the lens component 700 is mounted on the first mounting portion 610 of the support frame 600. In this embodiment, the lens component 700 is assembled and disassembled from the support frame 600 by pulling, which is convenient and quick.

[0098] Step S520, the absorption base 800 is mounted on the second mounting portion 620 of the support frame 600. In this embodiment, the absorption base 800 is assembled and disassembled from the support frame 600 by pulling, which is convenient and quick.

[0099] It is understandable that the order of step S510 and step S520 is not specifically limited here, and step S510 may be performed first and then step S520, or step S520 may be performed first and then step S510.

[0100] Step S530, tilt the support frame 600 according to the actual geographical location. In this embodiment, the tilt angle of the support frame 600 is the latitude of the actual geographical location. Taking Beijing as an example, Beijing is located in the northern hemisphere, at a latitude of 40 degrees north. The support frame 600 is tilted toward the south, and its tilt angle is 40 degrees, which can greatly improve the utilization rate of sunlight.

[0101] Taking the winter solstice and summer solstice in Beijing as an example, when the solar intelligent temperature control and energy saving device of the embodiment of the present invention is placed 40 degrees southward, the trajectory distribution diagram of the sun's movement on the summer solstice and winter solstice is as follows: Figure 8 shown.

[0102] It can be seen from the trajectory diagram of the sun's movement that the altitude angles of sunlight on the winter solstice and the summer solstice are symmetrically distributed on both sides of the normal line of the ground. That is, sunlight will be incident from both sides of the bottom surface normal line of the lens component 700 on the winter solstice (low radiation intensity) and the summer solstice (high radiation intensity). Therefore, the sunlight passing through the lens component 700 can be divided and focused to the north and south sides of the lens component 700, and finally reach the areas of different absorption materials of the absorption base 800 (i.e., the first absorption area 810 or the second absorption area 820), thereby achieving temperature control.

[0103] Taking Beijing as an example, when the solar intelligent temperature control and energy saving device of the embodiment of the invention is placed at a 40 degree tilt to the south, the distribution diagram of the light spots formed on each absorption step after the sunlight passes through the lens component 700 from 10:00 to 14:00 on the winter solstice and the summer solstice is as follows: Fig. 9 shown.

[0104] It is understandable that when the light spot moves to the junction of the absorption steps, since the upper surface and the side surface of the absorption step are covered with the first absorption layer or the second absorption layer for regulating absorption, the light spot at the junction of two adjacent absorption steps can also be regulated.

[0105] When the light spot converges on the north side (i.e., the first absorption zone 810), the north side is covered with a material with a high absorption rate, and the sunlight will be absorbed by the first absorption layer with a high absorption rate, and the absorption base 800 will be in a high temperature state, which is suitable for keeping warm during low solar radiation. When the light spot converges on the south side (i.e., the second absorption zone 820), the sunlight is concentrated on the second absorption layer with a low absorption rate, and the sunlight is less absorbed, and the absorption base 800 will be in a low temperature state, which is suitable for cooling during high solar radiation.

[0106] It can be understood that since the front and rear walls of the support frame 600 have a limiting effect on the absorption base 800 and the lens component 700, the inclination of the support frame 600 will not allow the absorption base 800 and the lens component 700 to automatically escape from the absorption chamber. During use, the absorption base 800 and the lens component 700 are stably placed in the absorption chamber.

[0107] Fig.10 This is an experimental temperature curve diagram of the solar intelligent temperature control and energy saving device of an embodiment of the present invention on the winter solstice and summer solstice in Beijing in 2023, wherein the absorptivity of the high-absorption material on the north side (i.e., the first absorption layer) is 0.9, and the emissivity is 0.75, and the absorptivity of the low-absorption material on the south side (i.e., the second absorption layer) is 0.25, and the emissivity is 0.75. Simulation calculations were performed on ideal heating materials (absorptivity is 1, and emissivity is 0) and ideal cooling materials (absorptivity is 0, and emissivity is 1). Among them, the upper boundary of area 1 is the temperature curve of the ideal heating material on the summer solstice, and the lower boundary is its temperature curve on the winter solstice; the upper boundary of area 2 is the temperature curve of the ideal cooling material on the summer solstice, and the lower boundary is its temperature curve on the winter solstice; the upper boundary of area 3 is the temperature curve of the solar intelligent temperature control and energy saving device using this embodiment on the summer solstice, and the lower boundary is its temperature curve on the winter solstice.

[0108] Depend on Fig.10 It can be seen that when using the solar intelligent temperature control and energy-saving device of the embodiment of the present invention, under the conditions of high radiation (summer solstice) and low radiation (winter solstice), the temperature change range (area 3) is significantly smaller than the temperature change range of a single heating material (area 1) and the temperature change range of a single cooling material (area 2).

[0109] Since the existing refrigeration or heating materials have fixed absorption and emission properties, their own temperature is prone to extreme heat or cold when the external environment changes. The solar energy intelligent temperature control and energy saving device of the embodiment of the present invention realizes adaptive adjustment to environmental changes through the linkage between the lens component 700 and the first absorption area 810 and the second absorption area 820 of the absorption base 800, thereby controlling absorption and emission, and then adjusting the temperature. This makes the temperature range of the space using the solar energy intelligent temperature control and energy saving device of this embodiment closer to the comfortable living environment temperature, especially when the external radiation changes.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
