Abstract
Description
Technical Field
[0001] This invention specifically relates to a self-regulating closed-loop enclosure wall for all seasons and the airflow regulation method thereunder, belonging to the field of building structure technology. Background Technology
[0002] Temperature is a crucial adaptability indicator affecting buildings. It influences the indoor living environment because indoor air constantly exchanges heat with the building envelope and outdoor air, resulting in constantly changing room temperature. Currently, there are many methods for regulating indoor temperature, but these are all energy-intensive. According to a building energy consumption research report, building operation energy consumption accounts for 22% of the country's total energy consumption, making it crucial to reduce building operation energy consumption. The thermal performance of the building envelope plays a decisive role in reducing building operation energy consumption. Currently, building envelope energy-saving technologies have limitations in heat (cold) loss or severe seasonal limitations. Corresponding technologies can be summarized into three categories: increasing the thickness of the insulation layer, adding sunrooms, and applying radiant cooling coatings. However, increasing the thickness of the insulation layer can only reduce heating and cooling energy consumption, but still results in heat (cold) loss; adding a sunroom can heat the building by collecting solar energy on sunny days in winter, but it has no advantage at night and in summer, and will increase cooling energy consumption in summer; applying a radiant cooling coating can actively cool by reflecting sunlight and radiating heat to the atmosphere through windows, and the roof cooling effect is significant in summer, but the cooling efficiency is limited by the reflection angle of the exterior wall, and the radiant cooling coating will increase heating energy consumption during the heating season.
[0003] Recently, to address the issue of seasonal limitations, researchers have integrated motors into building envelopes, switching operating modes by power to achieve radiant cooling in summer and heating in winter. While this method solves the seasonal limitation problem, this "active" approach results in additional energy consumption. From a total energy perspective, this technology offers no advantage over traditional techniques that involve thickening the insulation layer, thus failing to meet the demand for low-energy use throughout the year and lacking a building configuration structure capable of self-circulation. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, a self-regulating closed-loop enclosure wall with airflow regulation for all seasons and the airflow regulation method thereunder are provided to solve the above problems.
[0005] The all-season self-regulating closed-loop enclosure wall includes an outer light-concentrating cover and a main wall. The outer light-concentrating cover is provided outside the main wall. A pre-positioned cavity is formed between the inner wall of the outer light-concentrating cover and the outer wall of the main wall. A light-absorbing layer and a reflective coating are vertically arranged from top to bottom on the outer wall of the main wall. Both the light-absorbing layer and the reflective coating face the outer light-concentrating cover. At least one upper airflow communication hole connected to the pre-positioned cavity is machined on the top of the main wall. At least one lower airflow communication hole connected to the pre-positioned cavity is machined on the bottom of the main wall.
[0006] A method for quantitatively configuring the height of the enclosure is implemented using the all-season self-regulating closed-loop enclosure wall described in specific embodiments one, two, three, or four. The prerequisite for the quantitative configuration method of the enclosure height is that after selecting the maximum limit value of the solar incident angle in winter and the minimum limit value of the solar incident angle in summer on the south facade of the building, the height of the light-absorbing layer and the reflective coating is set to 0.5m, the distance from the solar incident ray to the top of the outer concentrating enclosure is h, the maximum limit value of the solar incident angle in winter is 20°, and the minimum limit value of the solar incident angle in summer is 60°.
[0007] When 0 < h < 0.5m, ensure that the light deflection angle δ meets the requirement of being within the deflection angle range formed between curve b and curve e;
[0008] When h = 0, the light deflection angle δ is set to 0°, where δ is the change in angle of the refracted ray relative to the incident ray. To ensure the position of curve e is achieved, the distance from the outer focusing cover to the main wall is: d = 0.5 × tan30° = 0.28868m. When h = 0.5m, to ensure the position of curve b is achieved, the light deflection angle δ is set to 20°. When the light deflection angle is 20°, the corresponding curve for summer is f, which meets the requirements of the deflection angle range.
[0009] When 0.5m < h < 1m, ensure that the light deflection angle δ at least satisfies curve d. At this time, the light deflection angle δ is 80°, and h = 1m. When h = 0.5m, the light deflection angle is 32°, which is curve c. When the light deflection angle is within the range of curves c and d, the focusing angle requirements for winter and summer can be met simultaneously.
[0010] The specific process of the quantitative configuration method for the hood height is as follows:
[0011] The relationship between the distance h from the top of the outer concentrator to the incident sunlight and the angle δ of the sunlight is as follows:
[0012] δ=δ 左 +δ 右 , where δ 左 It is the light deflection angle on the left side of the outer focusing mask, δ 右 It is the light deflection angle on the right side of the outer focusing mask;
[0013] When 0 < h < 0.5 m,
[0014]
[0015] Right now,
[0016] When 0.5m < h < 1m,
[0017]
[0018] Right now,
[0019] From the condition of equal optical path length, the formulas relating the convexity angle α to the incident angle and δ angle can be derived:
[0020]
[0021] In the above formula, n' is the refractive index of air; n is the refractive index of the outer light-concentrating mask.
[0022] Substituting the angle of incidence, δ angle, etc., into the above formula, we can further derive:
[0023] ① When 0 < h < 0.5 m, the outer wall of the centrally placed vertical plate is a plane wall, i.e., ɑ 左 =0, when the inner wall of the central vertical plate is integrally connected with an inner convex ridge; that is, δ 左 =7°, U2=-13°, U3=-13°+δ 右 ;ɑ 左 The angle between the convex ridge and the central axis along the height direction of the outer light-gathering cover; α 右 U1 is the angle between the inner convex ridge and the central axis of the outer light-concentrating cover in the height direction; U2 is the angle between the backward extension of the incident light ray when it passes through the outer convex ridge and the horizontal ground; U3 is the angle between the backward extension of the incident light ray when it passes through the inner convex ridge and the horizontal ground.
[0024]
[0025]
[0026] so,
[0027] ② When 0.5m < h < 1m, the outer and inner walls of the central vertical plate are integrally connected with multiple outwardly protruding ribs and multiple inwardly protruding ribs, respectively. This area is arranged according to δ 左 =δ 右 To deduce, specifically:
[0028] Left side: U3 = 20°, U2 = U3 - δ 左 =20°-δ 左
[0029] so,
[0030] because And δ 左 =δ 右
[0031] so,
[0032] so
[0033] Right side: U2 = δ 左 -20°, U3=U2+δ 右 δ 左 +δ 右 =δ m ;
[0034]
[0035]
[0036] That is, when 0 < h < 0.5 m,
[0037] δ 左 =7°;
[0038] α 左 =0,
[0039] When 0.5m < h < 1m,
[0040]
[0041]
[0042]
[0043] An airflow regulation method is implemented using the all-season self-regulating closed-loop enclosure wall described in specific embodiments one, two, three, four, five, six, seven, or eight. The airflow regulation method involves using the differences in solar altitude angles across seasons to achieve real-time and continuous adjustment of the indoor temperature. Specifically:
[0044] When the all-season self-regulating closed-loop building envelope is in use during the heating season, the light-absorbing layer is in its main operating state. During the daytime hours of the heating season, the spectral adaptive coating located in the adaptive zone absorbs the light refracted by the outer focusing cover, and the concentrated radiation raises the temperature. The temperature control critical value of the spectral adaptive coating is 81.1-83.7℃. When the temperature of the spectral adaptive coating exceeds the temperature control critical value, the spectral adaptive coating is in a heat-absorbing state, transferring the heat to the energy storage layer for storage. At the same time, the spectral adaptive coating heats the air in the pre-air cavity. The heated air generates buoyancy and carries the heat back into the room through the upper airflow connection hole. The cold air in the room enters the pre-air cavity through the lower airflow connection hole under the action of thermosiphon and is heated by the spectral adaptive coating, forming hot air that enters the room through the upper airflow connection hole. This cycle repeats, achieving the process of providing continuous heat to the room during the day.
[0045] During the nighttime hours of the heating season, the energy storage layer releases heat as a heat source to heat the air, thus providing continuous heating for the building even at night. The energy storage layer located in the adaptive zone releases heat to heat the air in the pre-heating cavity. The heated air generates buoyancy and carries the heat back into the room through the upper airflow connection hole. The cold air in the room enters the pre-heating cavity through the lower airflow connection hole under the action of thermosiphon and is mixed with the heat released by the energy storage layer, forming warmer air that enters the room through the upper airflow connection hole. This cycle repeats, thus providing continuous heat to the room at night.
[0046] When this invention is used during the cooling season, the reflective coating is mainly used during the daytime of the cooling season when it is in the main operating state. The working process is as follows: During the daytime of the cooling season, sunlight shines into the front nanocavity through the outer concentrator. The reflective coating in the reflective area reflects most of the solar energy to the outer concentrator, with a reflectivity between 93% and 97%. The spectral adaptive coating in the adaptive area has no solar radiation and its temperature is below the temperature control threshold, so it is in radiation cooling mode. Since the concentrator glass can change its emission direction, the spectral adaptive coating continuously emits heat toward the outer concentrator, and the reflected sunlight penetrates to the outside through the outer concentrator.
[0047] The beneficial effects of this invention are as follows:
[0048] I. This invention enables the main wall to coordinate the regulation of indoor airflow and temperature by working together with the outer light-concentrating cover, the main wall, the front-mounted cavity, the light-absorbing layer, the reflective coating, the upper airflow connecting hole, and the lower airflow connecting hole. This helps to improve the comfort of indoor living and allows for the use of temperature differences throughout the seasons to adapt to different usage modes for heating and cooling seasons.
[0049] Second, the outer light-concentrating cover in this invention is a light-concentrating component specially adapted to the main wall, which can achieve a large-area effective light-concentrating effect and provide continuous and stable heat energy for the heat absorption of the main wall.
[0050] Third, in daily use, when the invention is used during the day, the outer light-concentrating cover, the main wall and the light-absorbing layer work together to absorb solar radiation and store heat in the light-absorbing layer. When used at night, the light-absorbing layer releases the stored heat into the room to increase the room temperature, ensuring that the temperature of the main wall has the maximum effect on maintaining the balance of the indoor thermal environment, especially the nighttime temperature.
[0051] Fourth, when this invention is used during the heating season, the outer light-concentrating cover, the main wall, and the light-absorbing layer work together to achieve the energy storage process. At the same time, when needed, a cold air flow is formed through the lower airflow connection hole, while the light-absorbing layer releases heat. The cold air forms a hot air flow under the influence of the heat release of the light-absorbing layer. The hot air flow enters the indoor position behind the main wall through the upper airflow connection hole, thereby forming a process of raising the indoor temperature during the heating season.
[0052] Fifth, when used during the cooling season, the outer light-concentrating cover, the main wall, the light-absorbing layer, and the reflective coating work together to refract solar energy, preventing direct sunlight from entering the room. When it is necessary to further reduce the indoor temperature, the heat energy of the light-absorbing layer and the reflective coating is released and further discharged outdoors through the outer light-concentrating cover, thereby further reducing the indoor temperature and forming a process of reducing the indoor temperature during the cooling season.
[0053] VI. This invention allows for self-adjustment of heating during the heating season and cooling during the cooling season, without consuming excessive additional electrical or mechanical energy. This invention also features a low-energy-consumption process for the building envelope during both heating and cooling seasons. Furthermore, this invention improves the effective utilization rate of solar energy. After concentrating the light, the temperature in the adaptive zone is significantly increased, resulting in a larger temperature gradient and thus enhancing the effective utilization rate.

Detailed Implementation
[0084] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
[0085] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 , Figure 27 , Figure 28 and Figure 29 This embodiment describes a self-regulating closed-loop enclosure wall that operates in all seasons. It includes an outer light-concentrating cover 1 and a main wall 2. The outer light-concentrating cover 1 is a transparent material with a varying thickness, designed to allow light to pass through under different seasons, temperatures, and angles. The outer light-concentrating cover 1 is positioned around the main wall 2, enclosing its front side. A front-mounted cavity 3 is formed between the inner wall of the outer light-concentrating cover 1 and the outer wall of the main wall 2. This front-mounted cavity 3 is a sealed cavity formed between the outer light-concentrating cover 1 and the main wall 2, serving as the main wall... 2. The released heat provides a buffering space to achieve the initial heat release buffering process. The outer wall of the main wall 2 is vertically arranged with a light-absorbing layer 4 and a reflective coating 5 from top to bottom. Both the light-absorbing layer 4 and the reflective coating 5 are arranged facing the outer light-concentrating cover 1. The top of the main wall 2 is processed with at least one upper airflow communication hole 6 connected to the front-mounted cavity 3. The bottom of the main wall 2 is processed with at least one lower airflow communication hole 7 connected to the front-mounted cavity 3. The front-mounted cavity 3, the upper airflow communication hole 6 and the lower airflow communication hole 7 are interconnected to form an airflow channel. The airflow channel is used to connect with the indoor space to regulate and affect the indoor temperature.
[0086] In the front nanocavity 3, the front nanocavity 3 is divided into an adaptive region and a reflective region by setting the light-absorbing layer 4 and the reflective coating 5. The space between the outer wall of the light-absorbing layer 4 and the inner wall of its corresponding outer light-concentrating cover 1 is the adaptive region, and the space between the outer wall of the reflective coating 5 and the inner wall of its corresponding outer light-concentrating cover 1 is the reflective region. The adaptive region is located above the reflective region.
[0087] Furthermore, the light-absorbing layer 4 includes a spectrally adaptive coating 4-1 and an energy storage layer 4-2. The spectrally adaptive coating 4-1 and the energy storage layer 4-2 are vertically arranged sequentially from the outside to the inside on the outer wall of the main wall 2, with the outer wall of the energy storage layer 4-2 closely adhering to the inner wall of the spectrally adaptive coating 4. The spectrally adaptive coating 4-1 is obtained by using magnetron sputtering deposition or pulsed laser deposition to composite vanadium dioxide, a heat-absorbing material, and a radiation-cooling material. The specific performance requirements for the spectrally adaptive coating 4-1 are as follows:
[0088] Furthermore, the height of the outer light-concentrating cover 1 is equal to the height of the main wall 2.
[0089] The spectral adaptive coating 4-1 can absorb and release heat after sensing its own temperature without the need for electronic control. The temperature control critical value of the spectral adaptive coating 4-1 is 67.8-68.9℃. When the temperature of the spectral adaptive coating 4-1 is below the temperature control critical value, it operates in radiative cooling mode. The corresponding wavelength range for the spectral adaptive coating 4-1 is the atmospheric window band of 8-13μm, with an emissivity greater than 0.85, and in the solar radiation band of 0.3-2.5μm, with an absorptivity less than 0.73. When the temperature of the spectral adaptive coating 4-1 is above the temperature control critical value, it operates in heat absorption mode. The corresponding wavelength range for the spectral adaptive coating 4-1 is the atmospheric window band of 8-13μm, with an emissivity less than 0.18, and in the solar radiation band of 0.3-2.5μm, with an absorptivity greater than 0.91.
[0090] Among them, the energy storage layer 4-2 is composed of a composite of foamed metal and organic matter, with a thermal conductivity greater than 6.63 W / (m·K) and a latent heat of phase change greater than 417 kJ / kg.
[0091] A reflective coating 5 is formed by coating the main wall 2 with reflective paint. The reflective coating 5 is composed of a high reflectivity composite material or a high reflectivity metal layer. The reflective coating 5 can reflect solar incident light with wavelengths between 180-2500nm and ensure a reflectivity of over 93%, with a maximum value of 97%.
[0092] Specific Implementation Method Two: Combining Figures 1 to 6 This embodiment is a further limitation of the first specific embodiment. The outer light-concentrating cover 1 is a glass cover, and the outer light-concentrating cover 1 is a U-shaped straight cover. The outer light-concentrating cover 1 includes an upper component plate 11-1, a middle vertical plate 11-2, and a lower component plate 11-3. The upper component plate 11-1 and the lower component plate 11-3 are arranged horizontally from top to bottom. The middle vertical plate 11-2 is arranged vertically between the upper component plate 11-1 and the lower component plate 11-3. The outer wall of the middle vertical plate 11-2 has a plurality of outwardly protruding ribs 12-1 arranged sequentially along its height direction. The plurality of outwardly protruding ribs 12-1 are arranged near the bottom of the middle vertical plate 11-2. The inner wall of the middle vertical plate 11-2 has a plurality of inwardly protruding ribs 12-2 arranged sequentially along its height direction.
[0093] Furthermore, the outer light-concentrating cover 1 has a high degree of fine structure, with the spacing between two adjacent outer convex ribs 12-1 reaching less than 0.3 mm and the spacing between two adjacent inner convex ribs 12-2 reaching less than 0.3 mm.
[0094] Furthermore, multiple outward protruding ribs 12-1 are concentrated on the lower half of the outer wall of the central vertical plate 11-2, the upper half of the outer wall of the central vertical plate 11-2 is a straight wall, and multiple inward protruding ribs 12-2 are distributed on the entire inner wall of the central vertical plate 11-2.
[0095] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. In this implementation method, the outer focusing cover 1 is a glass cover. The outer focusing cover 1 is a U-shaped inclined cover, that is, the longitudinal cross-sectional shape of the outer focusing cover 1 along its height direction is an inclined U-shape. The outer focusing cover 1 includes a narrow plate 1-1, a wide plate 1-2 and an inclined corrugated plate 1-3. The narrow plate 1-1 and the wide plate 1-2 are arranged horizontally from top to bottom. The length of the narrow plate 1-1 is less than the length of the wide plate 1-2. The inclined corrugated plate 1-3 is inclined between the narrow plate 1-1 and the wide plate 1-2. The high side of the inclined corrugated plate 1-3 is integrally connected to the outer side of the narrow plate 1-1. The inner side of the narrow plate 1-1 is connected to the outer wall of the main wall 2. The bottom side of the inclined corrugated plate 1-3 is integrally connected to the outer side of the wide plate 1-2. The inner side of the wide plate 1-2 is connected to the outer wall of the main wall 2.
[0096] In this embodiment, the outer light-concentrating cover 1 has a bottom-to-top converging structure, which is more conducive to adapting to the angle of light in different seasons, ensuring that it matches different angles of solar radiation in all four seasons, and facilitating the collection and storage of heat.
[0097] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One, Two or Three. In this implementation method, the inclined corrugated plate 1-3 includes a plate body 1-3-1. The inner wall of the plate body 1-3-1 is integrally connected with a plurality of protrusions 1-3-2 from top to bottom. The top of the protrusions 1-3-2 is a plane, the outer wall of the protrusions 1-3-2 is an arc-shaped wall, the top of the protrusions 1-3-2 is a straight part, and the thickness of the protrusions 1-3-2 decreases from top to bottom.
[0098] In this embodiment, the plate body 1-3-1 is a flat plate structure made of glass, and multiple protrusions 1-3-2 are integrally connected to the plate body 1-3-1 to form a light-concentrating inner wall structure with multiple continuous serrations.
[0099] Furthermore, the vertical distance between the straight portions of two adjacent protrusions 1-3-2 is 1.3 cm.
[0100] Furthermore, the shape of the protrusions 1-3-2 allows them to create different light-gathering effects. The light-gathering multiple protrusions 1-3-2 increase sequentially from top to bottom along the length of the plate body 1-3-1, thereby increasing the angle at which the outer light-gathering cover 1 changes the incident sunlight. The outer light-gathering cover 1 can handle a spectrum with wavelengths between 180-2500nm and a transmittance greater than 98%, and a reflectance greater than 40% and a transmittance less than 10% in the 2500nm-25000nm range.
[0101] The structure of the focusing glass cover 1 in this embodiment can be adapted to the solar altitude angle in different seasons.
[0102] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Method 1, 2, 3 or 4. In this implementation method, each upper airflow communication hole 6 is detachably connected to an upper sealing plug 8, and each lower airflow communication hole 7 is detachably connected to a lower sealing plug 9.
[0103] The upper sealing plug 8 is designed to promptly seal the upper airflow communication hole 6 on the main wall 2, enabling on-demand sealing. The lower sealing plug 9 is designed to promptly seal the lower airflow communication hole 7 on the main wall 2, enabling on-demand sealing. This facilitates the use of the plug during the transition between heating and cooling seasons.
[0104] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. When there are multiple upper airflow connecting holes 6, the multiple upper airflow connecting holes 6 are arranged along the length direction of the main wall 2, and all the multiple upper airflow connecting holes 6 are located at the top of the main wall 2. The horizontal distance between two adjacent upper airflow connecting holes 6 is 1.5 to 2 meters. Correspondingly, when there are multiple lower airflow connecting holes 7, the multiple lower airflow connecting holes 7 are arranged along the length direction of the main wall 2, and all the multiple lower airflow connecting holes 7 are located at the top of the main wall 2. The horizontal distance between two adjacent lower airflow connecting holes 7 is 1.5 to 2 meters.
[0105] Furthermore, multiple upper airflow connecting holes 6 and multiple lower airflow connecting holes 7 can be staggered to facilitate the uniform penetration of cold and warm air, reduce the discomfort caused by indoor temperature differences due to cold and warm convection, and improve the comfort level of ventilation for heating or cooling.
[0106] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, or Six. In this implementation method, the structure of the upper airflow connecting hole 6 can be identical to that of the lower airflow connecting hole 7, and they are symmetrically arranged. Both ends of the upper airflow connecting hole 6 are wide-diameter openings, and the diameter of the upper airflow connecting hole 6 increases sequentially from the middle to both ends. This arrangement of the upper airflow connecting hole 6 creates an arc-shaped inner wall structure, which reduces useless energy consumption caused by vortices, thereby increasing energy utilization efficiency. The same principle applies to the purpose of the inner wall structure of the lower airflow connecting hole 7.
[0107] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six, or Seven. In this implementation method, the thickness of the reflective coating 5 is less than the thickness of the light-absorbing layer 4, and the length of the reflective coating 5 is equal to the length of the light-absorbing layer 4. This invention is applicable to walls exposed to sunlight, especially south-facing walls.
[0108] Specific Implementation Method Nine: Combining Figures 1 to 6 This embodiment describes a method for quantitatively configuring the height of a light-absorbing layer. The prerequisites for this method are: after selecting the maximum limit value of the solar incident angle in winter and the minimum limit value of the solar incident angle in summer on the south facade of the building, the height of the light-absorbing layer 4 and the reflective coating 5 are both set to 0.5m, the distance from the incident solar rays to the top of the outer light-concentrating cover 1 is h, the maximum limit value of the solar incident angle in winter is 20°, and the minimum limit value of the solar incident angle in summer is 60°.
[0109] When 0 < h < 0.5 m, at least the location requirements of curves b and e must be met;
[0110] When h = 0, the light deflection angle δ is set to 0°, where δ is the change in angle of the refracted light relative to the incident light. To ensure the realization of curve e, the distance from the outer focusing dome 1 to the main wall 2 is: d = 0.5 × tan30° = 0.28868m. When h = 0.5m, to ensure the realization of curve b, the light deflection angle δ is set to 20°. When the light deflection angle is 20°, the corresponding curve for summer is f, which meets the requirements of the location.
[0111] When 0.5m < h < 1m, at least curve d is satisfied. At this time, the light deflection angle δ is 80° and h = 1m. When h = 0.5m, the light deflection angle is 32°, which is curve c. It has been verified that when the light deflection angle is within the range of curves c and d, the focusing angle requirements for winter and summer can be satisfied at the same time.
[0112] The specific process of the quantitative configuration method for the hood height is as follows:
[0113] The relationship between the distance h from the top of the outer concentrator 1 to the incident sunlight and the angle δ of the sunlight is as follows:
[0114] δ=δ 左 +δ 右 , where δ 左 It is the light deflection angle on the left side of the outer focusing mask 1, δ 右 It is the light deflection angle on the right side of the outer focusing cover 1;
[0115] When 0 < h < 0.5 m,
[0116]
[0117] Right now,
[0118] When 0.5m < h < 1m,
[0119]
[0120] Right now,
[0121] From the condition of equal optical path length, the formulas relating the convexity angle α to the incident angle and δ angle can be derived:
[0122]
[0123] In the above formula, n' is the refractive index of air; n is the refractive index of the outer light-concentrating cover 1, where the refractive index of the outer light-concentrating cover 1 is the same as the refractive index of glass;
[0124] Substituting the angle of incidence, δ angle, etc., into the above formula, we can further derive:
[0125] ① When 0 < h < 0.5m, the outer wall of the central vertical plate 11-2 is a plane wall, i.e., ɑ 左 =0, when the inner wall of the central vertical plate 11-2 is integrally connected with the inner protruding rib 12-2; that is, δ 左 =7°, U2=-13°, U3=-13°+δ 右 ;ɑ 左 The angle between the convex ridge 12-1 and the central axis of the outer light-concentrating cover 1 in the height direction; α 右 U1 is the angle between the inner convex ridge 12-2 and the central axis of the outer light-concentrating cover 1 in the height direction; U2 is the angle between the backward extension of the incident light ray when it passes through the outer convex ridge 12-1 and the horizontal ground; U3 is the angle between the backward extension of the incident light ray when it passes through the inner convex ridge 12-2 and the horizontal ground; U2 is also the angle between the backward extension of the incident light ray when it passes through the outer convex ridge 12-1 and the thickness direction of the outer light-concentrating cover 1; U3 is also the angle between the backward extension of the incident light ray when it passes through the inner convex ridge 12-2 and the horizontal ground;
[0126]
[0127]
[0128] so,
[0129] ② When 0.5m < h < 1m, the outer and inner walls of the central vertical plate 11-2 are integrally connected with multiple outwardly protruding ribs 12-1 and multiple inwardly protruding ribs 12-2, respectively. This area is arranged according to δ 左 =δ 右 To deduce, specifically:
[0130] Left side: U3 = 20°, U2 = U3 - δ 左 =20°-δ 左
[0131] so,
[0132] because And δ 左 =δ 右
[0133] so,
[0134] so
[0135] Right side: U2 = δ 左 -20°, U3=U2+δ 右 ,δ 左 +δ 右 =δ m ;
[0136]
[0137]
[0138] That is, when 0 < h < 0.5 m,
[0139] δ 左 =7°;
[0140] α 左 =0,
[0141] When 0.5m < h < 1m,

[0145] In practical use, this embodiment obtains the maximum solar incidence angle in winter and the minimum solar incidence angle in summer on the south facade of the specific region. Then, it combines the specific height values of the light-absorbing layer 4 and the reflective coating 5 in the building design and substitutes them into the above-mentioned quantitative configuration method for the height of the cover to calculate the corresponding dimensions of the outer convex rib 12-1 and the inner convex rib 12-2 in the light-concentrating glass cover 1. This ensures that the present invention can continuously and effectively absorb sunlight and self-regulate the indoor temperature airflow during all seasons.
[0146] Specific Implementation Method Ten: Combining Figure 24 and Figure 25 This embodiment further defines embodiment nine. In this embodiment, the light deflection angle δ has an extreme value, exceeding which total internal reflection occurs. This extreme value is related to the refractive indices of the two media. When the refractive index n' of air is 1 and the refractive index n of glass is 1.5, the light deflection angle δ satisfies the following formula:
[0147] Specific Implementation Method Ten: Combining Figure 24 and Figure 25 This embodiment further defines embodiment nine. In this embodiment, the light deflection angle δ has an extreme value, exceeding which total internal reflection occurs. This extreme value is related to the refractive indices of the two media. When the refractive index n' of air is 1 and the refractive index n of glass is 1.5, the light deflection angle δ satisfies the following formula:
[0148]
[0149] δ 最大 ≈48°; δ 最大 This is the maximum angle of deflection of light on one side (i.e., the maximum value on one side);
[0150] Therefore, when n' = 1 and n = 1.5, the maximum ray deflection angle δ 最大 The angle is 48°. The maximum ray deflection angle required by the calculations for this invention is 40°, that is, when h = 1m, α 右 =40°, which is less than the extreme value of 48°, thus meeting the requirements and realizing the relevant conditions for the light deflection angle δ required by the present invention.
[0151] Detailed Implementation Method Eleven: Combining Figures 1 to 20 This embodiment describes an airflow regulation method achieved using an enclosing wall.
[0152] Combination Figure 14As shown, this invention can utilize the differences in solar altitude angles in different seasons to achieve corresponding indoor temperature regulation. Due to its structural characteristics, the outer concentrator 1 can focus solar incident rays 13 at different altitude angles onto different areas. When this invention is used during the heating season, the light-absorbing layer 4 is in its main operating state, and the working process is as follows:
[0153] During the daytime hours of the heating season, the spectral adaptive coating 4-1 located in the adaptive zone absorbs the light refracted by the outer concentrator 1. After concentrating and radiating light, the temperature rises. When the temperature exceeds the critical value, the spectral adaptive coating 4-1 automatically transforms into a heat-absorbing material and transfers the heat to the energy storage layer 4-2 for storage. At the same time, the spectral adaptive coating 4-1 heats the air in the pre-cavity 3. The heated air generates buoyancy and carries the heat back into the room through the upper airflow connection hole 6. The cold air in the room enters the pre-cavity 3 through the lower airflow connection hole 7 under the action of thermosiphon and is heated by the spectral adaptive coating 4-1. The hot air then enters the room through the upper airflow connection hole 6. This cycle repeats, achieving the process of providing continuous heat to the room during the day.
[0154] The principle behind the automatic transformation of the spectrally adaptive coating 4-1 into an endothermic material when the temperature exceeds the critical temperature control value is that the spectrally adaptive coating is prepared by deposition of modified VO2, an endothermic layer, and an infrared emitting layer. Because modified VO2 undergoes a phase transition under temperature influence—specifically, it is in an insulating state at lower temperatures and a metallic state above the phase transition temperature—its optical properties change before and after the phase transition. Therefore, a spectrally self-adjusting coating can be prepared using VO2 as the base material. The spectral characteristics of the coating are completely different when the temperature is below and above the phase transition critical value, thus achieving spectral self-adjustment and self-regulation through its own temperature.
[0155] During the nighttime hours of the heating season, the energy storage layer 4-2 acts as a heat source, releasing heat to heat the air and providing continuous heating for the building even at night. Located in the adaptive zone, the energy storage layer 4-2 releases heat to heat the air in the pre-cavity 3. The heated air generates buoyancy and carries the heat back into the room through the upper airflow connection hole 6. The cold indoor air enters the pre-cavity 3 through the lower airflow connection hole 7 under the action of thermosiphon and is mixed with the heat released by the energy storage layer 4-2, forming warmer air that enters the room through the upper airflow connection hole 6. This cycle repeats, providing continuous heat to the room at night.
[0156] When this invention is used during the cooling season, the reflective coating 5 is mainly used during the daytime during the cooling season when it is in its main operating state. The working process is as follows:
[0157] During the daytime hours of the cooling season, sunlight shines into the front nanocavity 3 through the outer concentrator 1. The reflective coating 5 in the reflective area reflects most of the solar energy to the outside of the outer concentrator 1. The spectral adaptive coating 4-1 in the adaptive area has no solar radiation and its temperature is below the temperature control threshold, so it is in radiative cooling mode. Since the concentrator glass cover 1 can change its emission direction, the spectral adaptive coating 4-1 can continuously emit heat toward the outer concentrator 1. The reflected sunlight 14 is penetrated to the outside through the outer concentrator 1, thereby achieving the effect of cooling the room and achieving the purpose of indirect shading.
[0158] This invention provides both shading and passive cooling functions during the cooling season, thereby achieving the goal of passive cooling. Through automatic light-gathering technology, spectral self-adjustment technology, and breathable technology, this invention achieves energy harvesting, storage, and release during the heating season, and shading and radiative cooling during the cooling season. This ensures that the building envelope has no heat or cold loss throughout the year, while simultaneously providing heating or cooling for the building, achieving continuous, low-energy regulation of indoor air temperature. This invention is beneficial for studying the temporal and spatial variations of wall temperature with air temperature, providing a scientific basis for indoor temperature management and wall design and construction in buildings.
[0159] After conducting specific experiments and tests, the relevant conclusions of this invention are as follows:
[0160] The temperature control critical value of this invention is determined based on the phase transition temperature characteristics of VO2, which will undergo a phase transition at 68℃. Through "ultraviolet-visible-near-infrared spectrophotometry" test, it was found that the spectral adaptive coating undergoes a transition in absorptivity and emissivity at 67.8-68.9℃.
[0161] In winter, i.e. the heating season, the higher the absorptivity in the solar radiation band of 0.3-2.5μm, the better, and the lower the emissivity in the atmospheric window of 8-13μm, the better.
[0162] In summer, during the cooling season, the lower the emissivity of the atmospheric window in the range of 8-13 μm, the better. There is no mandatory requirement for the absorptivity in the solar radiation band in the range of 0.3-2.5 μm, mainly because sunlight is concentrated and does not reach this area, but it is still better to ensure that it is as low as possible.
[0163] Combination Figure 26 and Figure 27 As shown, experimental research has shown that when the emissivity is greater than 0.85 in the atmospheric window band of 8-13μm, it can achieve a cooling state throughout the day in summer; when the emissivity is less than 0.18 in the atmospheric window band of 8-13μm and the absorptivity is greater than 0.91 in the solar radiation band of 0.3-2.5μm, it can achieve a heating state throughout the day in winter.
[0164] Although the invention is limited by varying external temperatures in different regions, as long as the two main parameters of the external conditions are determined—the minimum and maximum solar incidence angles on the south facade in summer and winter—and the height of the outer concentrating cover 1 or the main wall 2, and by combining these three main parameters, the protrusions can be designed, and a research model can be established to study the outward and inward convex structures of the outer concentrating cover 1. The process involves using a quantitative configuration method for the cover height to configure a suitable all-season self-regulating closed-loop enclosure wall for the region, and then using this enclosure to achieve airflow regulation. Specifically, the light deflection angle δ at different positions h of the outer concentrating cover 1 is first determined, and then the protrusion angle at different positions h of the outer concentrating cover 1 is determined based on the light deflection angle δ.
[0165] Through several modeling calculations and experimental tests, this invention demonstrates that during winter use, the temperature of the light-absorbing layer 4, after being focused by the outer light-concentrating cover 1, can reach 107℃-189℃, while the indoor temperature mostly does not exceed 25℃. The daytime temperature difference is very large, and regardless of whether the indoor temperature is 0℃ or 25℃, strong natural convection will be formed, carrying the heat absorbed by the light-absorbing layer 4 into the room. At night, due to the absence of sunlight, the heat accumulated by the energy storage layer 4-2 during the day begins to be released. Experimental tests have shown that the temperature of the energy storage layer 4-2 at night is 87℃-71℃, which also has a large temperature gradient with the indoor temperature, and the temperature variation within the range of 107℃-189℃ is very small. Therefore, this invention is less affected by changes in the external ambient temperature, and this invention can achieve the purpose of indoor heating through natural convection.

An airflow regulation method, implemented using the all-season self-regulating closed-loop enclosure wall as described in any one of claims 1 to 8, characterized in that: The airflow regulation method utilizes the differences in solar altitude angles across seasons to achieve real-time and continuous adjustment of indoor temperature, specifically as follows: When the all-season self-regulating closed-loop enclosure wall is used during the heating season, the light-absorbing layer (4) is in the main operating state. During the daytime of the heating season, the spectral adaptive coating (4-1) located in the adaptive zone absorbs the light refracted by the outer light-concentrating cover (1), and heats up after concentrated radiation. The temperature control critical value of the spectral adaptive coating (4-1) is 67.8-68.9℃. When the temperature of the spectral adaptive coating (4-1) exceeds the temperature control critical value, the spectral adaptive coating (4-1) is in the heat-absorbing state and transfers the heat to the energy storage layer (4-2) for storage. At the same time, the spectral adaptive coating (4-1) heats the air in the pre-cavity (3). The air is heated and generates buoyancy. The heat is brought back to the room through the upper airflow connecting hole (6). The cold air in the room enters the pre-cavity (3) through the lower airflow connecting hole (7) under the action of thermosiphon and is heated by the spectral adaptive coating (4-1). The hot air enters the room through the upper airflow connecting hole (6). This cycle repeats, realizing the process of providing continuous heat to the room during the day. During the nighttime hours of the heating season, the energy storage layer (4-2) releases heat as a heat source to heat the air, thus achieving continuous heating for the building during the nighttime hours of the heating season. The energy storage layer (4-2) located in the adaptive zone releases heat to heat the air in the pre-mounted cavity (3). The heated air generates buoyancy and carries the heat back into the room through the upper airflow connection hole (6). The cold air in the room enters the pre-mounted cavity (3) through the lower airflow connection hole (7) under the action of thermosiphon and is mixed with the heat released by the energy storage layer (4-2) to form warmer air that enters the room through the upper airflow connection hole (6). This cycle repeats, thus achieving continuous heating for the room at night. When the all-season self-regulating closed-loop enclosure wall is used in the cooling season, the reflective coating (5) is mainly used during the daytime of the cooling season when it is in the main operating state. The working process is as follows: During the daytime of the cooling season, sunlight shines into the front nanocavity (3) through the outer concentrator (1). The reflective coating (5) in the reflective area reflects most of the solar energy to the outside of the outer concentrator (1), with a reflectivity between 93% and 97%. The spectral adaptive coating (4-1) in the adaptive area has no solar radiation and its temperature is below the temperature control threshold, so it is in radiation cooling mode. Since the concentrator glass cover (1) can change its emission direction, the spectral adaptive coating (4-1) continuously emits heat towards the outer concentrator (1), and the reflected sunlight (14) penetrates to the outside through the outer concentrator (1).
