The temperature control roof system comprises at least one reflecting plate; the two supporting plates are symmetrically arranged at the two ends of the reflecting plate so as to support the reflecting plate between the roof and the reflecting plate; the supporting plate is provided with two supporting edges which are intersected at an acute angle; wherein one supporting edge is used for being attached to the roof, and the other supporting edge is attached to the reflecting plate, so that an opening is defined between the reflecting plate and the supporting plate; the opening is used for emitting light to the roof. In combination with sun angle change and temperature dynamic change in four seasons of the year, when the sun angle is low and the environment temperature is low, most solar rays are emitted to the roof from the opening, and indoor heat is increased; when the sun angle is high and the environment temperature is high, most solar rays are reflected by the reflecting plate, the reflecting plate shields light rays for the roof, indoor heat is reduced, and therefore self-adaptive temperature adjustment based on dynamic changes of the sun angle is achieved.

Description

Technical Field

[0001] The present invention relates to the technical field of roof systems, and in particular to a temperature control roof system based on the sun angle. Background Art

[0002] With the increasing intensification of global climate change, energy conservation and emission reduction have become the core issues of global concern, and the thermal management performance of building envelopes has a direct impact on the overall energy consumption level. Heat loss in building energy consumption mainly stems from heat conduction and thermal radiation, and solar radiation is one of the main external heat sources. The peak value of solar radiation intensity received on the earth's surface can reach 1000 W / m2, of which about 47% is the energy of the infrared spectrum, which is the main component causing the thermal effect; therefore, effective regulation of solar radiation is of great significance for achieving building energy conservation.

[0003] Traditional building energy-saving designs mostly rely on changing the building orientation, optimizing the natural ventilation structure or using heat-insulating materials, etc. Although such static envelopes have the advantages of low cost and simple construction, their adjustment ability is fixed and it is difficult to adapt to the dynamic changes of solar radiation, so it is impossible to adaptively change the indoor temperature according to the continuous changes of the sun angle in different seasons.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a temperature control roof system based on the sun angle in view of the above-mentioned defects of the existing technology, aiming to adapt to the dynamic changes of solar radiation and thus adjust the indoor temperature.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0007] A temperature control roof system based on the sun angle, which includes:

[0008] At least one reflector;

[0009] Two support plates, symmetrically arranged at both ends of the reflector to support the reflector between the roof and the reflector; the support plates have two support edges intersecting at an acute angle; one of the support edges is used to fit with the roof, and the other support edge fits with the reflector to form an opening between the reflector and the support plate; the opening is used for light to shine on the roof.

[0010] In the temperature control roof system based on the sun angle, the support plate and the reflector are of an integrally formed structure.

[0011] The temperature control roof system based on the solar angle, wherein there are a plurality of the reflector plates, and the orientations of all the openings are the same; the plurality of the reflector plates are arranged in sequence in a direction perpendicular to the orientation of the openings.

[0012] The temperature control roof system based on the solar angle, wherein there are a plurality of the reflector plates, and the plurality of the reflector plates are arranged in sequence along the orientation of the openings.

[0013] The temperature control roof system based on the solar angle further includes:

[0014] A plurality of partition plates for being laid on the roof surface; one of the partition plates is arranged at each of the openings, and the partition plates are respectively connected to the support plates corresponding to the openings and the reflector plates opposite to the openings.

[0015] The temperature control roof system based on the solar angle, wherein the partition plates are reflective partition plates.

[0016] The temperature control roof system based on the solar angle, wherein the partition plates and the connected reflector plates are of an integrally formed structure.

[0017] The temperature control roof system based on the solar angle further includes:

[0018] A transparent plate laid on the roof surface and located within the projection area of the reflector plates towards the roof.

[0019] The temperature control roof system based on the solar angle, wherein the reflector plates are metal reflector plates.

[0020] Beneficial effects: When it is in a season with a lower solar angle, most of the sunlight can directly shine on the roof through the openings, thereby increasing the indoor temperature; while when it is in a season with a higher solar angle, most of the sunlight shines on the reflector plates and is reflected by the reflector plates, so that the light received by the roof is reduced, thereby lowering the indoor temperature. In this way, combined with the changes in the solar angle and the dynamic changes in temperature throughout the four seasons, when the solar angle is low and the ambient temperature is low, more sunlight shines on the roof through the openings, increasing the indoor heat; when the solar angle is high and the ambient temperature is high, more sunlight is reflected by the reflector plates, and the reflector plates block the light for the roof, reducing the indoor heat, thereby realizing the adaptive temperature adjustment based on the solar angle.

[0032] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms used herein (including technical terms and scientific terms) have the same meaning as the general understanding of those of ordinary skill in the art to which this application belongs. It should also be understood that terms defined in a general dictionary, for example, should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless specifically defined as here.

[0033] The present invention provides a temperature control roof system based on the sun angle, as Figure 1 and Figure 2 shown, the temperature control roof system based on the sun angle includes: at least one reflector 1 and two support plates 2; the two support plates 2 are symmetrically arranged at both ends of the reflector 1 to support the reflector 1 between the roof and the reflector 1; the support plate 2 has two support edges intersecting at an acute angle; one of the support edges is used to fit with the roof, and the other support edge fits with the reflector 1 to form an opening 3 between the reflector 1 and the support plate 2; the opening 3 is used for light to shine on the roof.

[0034] Specifically, the reflector 1 is used to reflect the received sunlight. Therefore, when the reflector 1 is arranged on the roof, the light irradiated on the reflector 1 will be reflected by the reflector 1, thereby reducing the light received by the roof at the position corresponding to the reflector 1, so as to achieve the purpose of reducing the indoor temperature. The two support plates 2 support the reflector 1 from both ends of the reflector 1, and there is an acute angle between the two support edges, so that after the reflector 1 and the support plate 2 are combined, the side of the reflector 1 close to the acute angle can be close to the roof, and the side of the reflector 1 away from the acute angle is tilted upward relative to the roof, like an inclined baffle; and an opening 3 is formed between the reflector 1 and the support plate 2.

[0035] After the support plate 2 is attached to the roof, the combination of the reflector 1 and the two support plates 2 forms a "cover" with the opening 3, covering the roof, and the reflector 1 creates a certain blockage on the roof. When it is in a season with a lower sun angle, most of the sunlight can directly shine on the roof through the opening 3, thus increasing the indoor temperature; while when it is in a season with a higher sun angle, most of the sunlight shines on the reflector 1 and is reflected by the reflector 1, reducing the light received by the roof and thus lowering the indoor temperature. In this way, combining the changes in the sun angle and temperature throughout the four seasons, when the sun angle is low and the ambient temperature is low, more sunlight shines on the roof through the opening 3, increasing the indoor heat; when the sun angle is high and the ambient temperature is high, more sunlight is reflected by the reflector 1, and the reflector 1 blocks the light for the roof, reducing the indoor heat, thereby achieving adaptive temperature regulation based on the sun angle.

[0036] Since China is located in the Northern Hemisphere and the sunlight comes from the south, and most of the housing buildings are designed with the orientation of facing south and north, the temperature control roof system based on the sun angle is laid on the roof surface, and the opening 3 is arranged facing south. Since the sun angle is low in winter and the sunshine path is inclined, the light enters from a lower angle, and the light can be guided to the roof through the opening 3, increasing the indoor heat; in summer, the sun angle is high and the sunshine path is steep, the light enters from a larger angle, so the light shining on the opening 3 is reduced, and the light is mainly concentrated on the reflector 1 and is reflected by the reflector 1, thereby reducing the indoor heat and achieving adaptive temperature adjustment.

[0037] At the same time, since the opening 3 is surrounded by the reflector 1 and the support plate 2, when the light shines on the roof from the opening 3, the inner side of the reflector 1 facing the roof will also receive a certain amount of light and reflect the light to the roof area within the opening 3, further increasing the indoor heat.

[0038] As Figure 3 shown, the slashes in the figure represent light; as the incident angle of the light changes, the reception and reflection of light by the temperature control roof system based on the sun angle will change dynamically. It can be found that the lower the incident angle of the light, the more light enters from the opening 3, and the less light is received and reflected by the reflector 1; the higher the incident angle of the light, the less light enters from the opening 3, and the more light is received and reflected by the reflector 1.

[0039] In this application, the end of the reflector 1 away from the opening 3 is attached to the roof to improve the stability of the assembly of the temperature control roof system based on the sun angle on the roof. The support plate 2 is a triangular support plate to improve the stability of the support of the support plate 2 for the reflector 1.

[0040] The support plate 2 can be a right - angled triangular support plate. One of the right - angled sides of the support plate 2 is used to fit the roof surface, the hypotenuse of the support plate 2 is used to fit the reflector 1, and the other right - angled side of the support plate 2 is used to support the reflector 1 and form the opening 3. The right - angled triangular shape of the support plate 2 is such that when the sun shines directly and the outdoor temperature is the highest, the roof surface exposed in the opening 3 can just coincide with the projection of the reflector 1 facing the roof, so that it is completely blocked by the reflector 1, improving the performance of the solar - angle - based temperature - controlled roof system in reducing heat entering the room when the temperature is the highest.

[0041] In one embodiment of the present application, the support plate 2 and the reflector 1 are of an integrally - formed structure.

[0042] Specifically, two support plates 2 are integrally formed and arranged on both sides of the reflector 1. If the support plate 2 and the reflector 1 are made of the same material, then the two support plates 2 are bent towards the same side of the reflector 1 and the support plate 2 is made perpendicular to the reflector 1, and thus the opening 3 can be formed.

[0043] In one embodiment of the present application, the reflector 1 is a metal reflector and the support plate 2 is also a metal support plate. Compared with the coated plate, both the reflector 1 and the support plate 2 being made of metal can better support their own structures; the metal material can more effectively reflect visible light and infrared light, reduce the heat load, further reduce the indoor temperature, and thus reduce the indoor cooling demand in summer. And the metal material is not easy to age and will not produce the phenomena of peeling, blooming, and blistering caused by the coating process.

[0044] In one implementation of this embodiment, both the reflector 1 and the support plate 2 are silver plates or aluminum plates to maximize the reflection of sunlight, while being durable, lightweight, easy to process, not easily degraded by ultraviolet rays, and suitable for long - term outdoor use.

[0045] There are multiple "cover" structures composed of the reflector 1 and the two support plates 2, and the arrangement of the "cover" structures can be distributed in rows horizontally or in columns vertically. Specifically:

[0046] Embodiment 1

[0047] There are multiple reflectors 1 and the orientations of all the openings 3 are the same; the multiple reflectors 1 are arranged in sequence along the direction perpendicular to the orientation of the opening 3. Specifically, the openings 3 are all arranged facing south, and the multiple reflectors 1 are arranged along the east - west direction, such that multiple "cover" structures are arranged horizontally along the roof surface, as Figure 1 shown.

[0048] In this embodiment, when the plurality of reflective panels 1 are arranged horizontally, every two adjacent reflective panels 1 are attached to each other, so that the temperature control roof system based on the sun angle can cover as much roof surface area as possible.

[0049] Embodiment 2

[0050] There are multiple reflective plates 1, and all openings 3 have the same orientation; multiple reflective plates 1 are arranged in sequence along the orientation of the openings 3. Specifically, the openings 3 are all arranged facing south, and multiple reflective plates 1 are arranged along the north-south direction, so that multiple "hood" structures are arranged longitudinally along the roof surface, such as Figure 2 shown.

[0051] In one implementation of the present embodiment, the temperature control roof system based on the sun angle also includes a plurality of isolation panels 4 for laying on the roof surface; an isolation panel 4 is provided at each of the openings 3, and the isolation panels 4 are respectively connected to the support panel 2 corresponding to the opening 3 and the reflective panel 1 opposite to the opening 3.

[0052] Specifically, the isolation plate 4 is between two adjacent reflecting plates 1 and is respectively connected to the adjacent supporting plate 2 and the reflecting plate 1, thereby isolating the two "cover" structures to extend the distance between the two adjacent reflecting plates 1 and reduce the shielding of the reflecting plate 1 on the opening 3 arranged opposite to it, thereby ensuring that when the sun angle is low, as much light as possible can pass through the opening 3 and reach the roof surface.

[0053] In one implementation of the present embodiment, the isolation plate 4 is a reflective isolation plate, and the isolation plate 4, the reflective plate 1 and the support plate 2 are made of the same material, so that the isolation plate 4 also has a reflective effect on light, thereby increasing the reflective area of the temperature control roof system based on the sun angle.

[0054] It can be seen that the isolation plate 4 can not only connect the two adjacent "cover" structures, so that the temperature control roof system based on the sun angle can form a whole, thereby facilitating the layout of the temperature control roof system based on the sun angle on the roof surface; the isolation plate 4 can also reflect light from the side of the reflective plate 1 away from the opening 3, thereby cooperating with the reflective plate 1 to increase the reflection area, enhance the light reflection effect, and further reduce the increase in indoor heat when the sun angle is large and the ambient temperature is high.

[0055] The isolation plate 4 and the connected reflective plate 1 are an integrally formed structure and are made of the same material, thereby further improving the structural strength of the temperature control roof system based on the sun angle and improving its stability in assembly on the roof surface.

[0056] The temperature control roof system based on the sun angle further includes a transparent plate 5 (as Figure 10 shown), and the transparent plate 5 is laid on the roof surface and is located within the projection area of the reflector 1 towards the roof.

[0057] Specifically, the transparent plate 5 is used to transmit light; when light enters from the opening 3, the transparent plate 5 receives the light and transmits the light, so that the light can enter the roof. The transparent plate 5 is respectively connected to the reflector 1 and the two support plates 2, thereby forming a three-dimensional triangular structure with the opening 3, further enhancing the structural strength of the "cover" structure and avoiding deformation due to environmental impact outdoors.

[0058] At the same time, the transparent plate 5 has a smooth surface, which is easier to wipe off the surface dust, shields the roof surface, reduces the coverage of dust on the roof surface, and enhances the effect of enhancing indoor heat after the light enters from the opening 3.

[0059] Applying the temperature control roof system based on the sun angle described in this application to the roof surface, comparing it with an absorptive roof (laying a light-absorbing material layer on the roof surface) and a reflective roof (laying a light-reflective material layer on the roof surface) respectively, and combining the annual temperature and sun angle data of places A and B (such as place A is Beijing and place B is Hong Kong), as Figures 4 - 9 shown, the results show that:

[0060] Whether it is place A or place B, in the first quarter (January to March), the heating demand is relatively high. The heating demand of the temperature control roof system based on the sun angle (as Figure 6 and Figure 9 shown) is higher than that of the absorptive roof (as Figure 5 and Figure 8 shown), but it is significantly better than that of the reflective roof (as Figure 4 and Figure 7 shown); as the temperature gradually rises (April and May), the heating demand drops significantly. This shows that the temperature control roof system based on the sun angle can effectively capture solar heat in the cold winter and reduce the demand for additional heating.

[0061] In summer (July to September), the cooling demand is relatively significant. The cooling demand of the temperature control roof system based on the sun angle (as Figure 6 and Figure 9 shown) is relatively lower than the cooling demand of the absorptive roof (as Figure 5 and Figure 8 shown), indicating that it adaptively reduces heat accumulation using the sun angle in summer, thereby reducing the demand for air conditioning energy consumption; compared with the reflective roof (as Figure 4 andFigure 7 As shown in [figure number], the peak refrigeration demand of the temperature control roof system based on the solar angle is also relatively close, indicating its effectiveness in blocking the incident sunlight in summer.

[0062] In summary, the present invention provides a temperature control roof system based on the solar angle, which includes: at least one reflector; two support plates symmetrically arranged at both ends of the reflector to support the reflector between the roof and the reflector; the support plate has two support edges intersecting at an acute angle; one of the support edges is used to fit with the roof, and the other support edge fits with the reflector to form an opening between the reflector and the support plate; the opening is used for light to shine on the roof. When in a season with a lower solar angle, most of the sunlight can directly shine on the roof through the opening, thereby increasing the indoor temperature; while when in a season with a higher solar angle, most of the sunlight shines on the reflector and is reflected by the reflector, so that the light received by the roof is reduced, thereby reducing the indoor temperature. In this way, combining the changes in the solar angle throughout the year and the dynamic changes in temperature, when the solar angle is low and the ambient temperature is low, more sunlight shines on the roof through the opening, increasing the indoor heat; when the solar angle is high and the ambient temperature is high, more sunlight is reflected by the reflector, and the reflector blocks the light for the roof, reducing the indoor heat, thereby realizing adaptive temperature adjustment based on the solar angle.
