Description

Technical Field

[0001] The present invention relates to the field of building technology, and more specifically, it relates to a Trombe wall. Background Art

[0002] A Trombe wall is a green building wall that makes full use of solar energy resources and has good energy-saving effects. Generally, a Trombe wall is applied to the south facade of a building and is composed of a glass on the outer layer of the building and a heavy heat storage wall with a certain distance from it. There is an air interlayer in the middle, and ventilation and air exchange devices are configured on both the glass panel and the heavy heat storage wall. During the day, the heat collection wall absorbs solar energy to heat the air passage, and the heated air floats up and supplies heat to the room through the upper ventilation opening; at night, the heat stored in the south wall is slowly released into the room for heating to avoid too large temperature fluctuations during the day. Traditional Trombe walls are mostly used for ventilation or heating. Under summer working conditions, the wall will absorb heat and cause the indoor temperature to be too high, affecting the comfort of users. Summary of the Invention

[0003] The present invention discloses a Trombe wall, which solves the problem that the Trombe wall in the prior art continuously absorbs heat under summer working conditions and causes the indoor temperature to be too high.

[0004] The present invention discloses a Trombe wall, including:

[0005] A wall;

[0006] A glass structure, which is arranged on the outer surface of the wall, and there is a first distance between the glass structure and the wall. A first communication port is arranged at the upper part of the glass structure, and a second communication port is arranged at the lower part. The first distance is communicated with the outside through the first communication port and the second communication port;

[0007] A louver structure, which is arranged in the first distance and has a first state and a second state;

[0008] When the louver structure is in the first state, sunlight cannot irradiate the wall through the louver structure;

[0009] When the louver structure is in the second state, sunlight can penetrate the louver structure and irradiate the wall;

[0010] A driving mechanism, which is arranged on the wall and / or the glass structure, and the driving mechanism is in transmission connection with the louver structure;

[0011] The driving mechanism can obtain the ambient temperature of the location where the Trombe wall is located to drive the louver structure to switch between the first state and the second state.

[0012] The driving mechanism includes a bimetallic strip, which is arranged on the wall and / or the glass structure, and the bimetallic strip is in transmission connection with the louver structure.

[0013] The bimetallic strip is in a spiral shape, and the first end of the spiral shape is fixedly arranged on the wall and / or the glass structure, and the second end is in transmission connection with the louver structure.

[0014] The driving mechanism further includes a first rotating shaft, which is rotatably arranged on the wall. The bimetallic strip is wound around the first rotating shaft, and the second end of the bimetallic strip is connected to the first rotating shaft. The louver structure is in transmission connection with the first rotating shaft, and the rotation of the first rotating shaft can drive the louver structure to rotate.

[0015] The number of the louver structures is multiple. All the louver structures are arranged in parallel within the first spacing, and all the louver structures are in transmission connection with the driving mechanism. When the louver structure is in the first state, among the adjacent two layers of the louver structures, the shadow of the upper layer of the louver structure is at least partially located on the lower layer of the louver structure. When the louver structure is in the second state, sunlight can irradiate the wall through the spacing between two adjacent louver structures.

[0016] A second rotating shaft is arranged on the louver structure, and the louver structure is rotatably arranged within the first spacing through the second rotating shaft.

[0017] The axis of the second rotating shaft is parallel to the horizontal plane; and / or, all the louver structures are arranged side by side in the vertical direction.

[0018] The cross-section of the louver structure is in a "one" shape, and the "one" shape has a first side surface capable of reflecting sunlight. When the louver structure is in the first state, the first side surface faces the glass structure; when the louver structure is in the second state, the first side surface faces the wall.

[0019] When the louver structure is in the first state, the plane where the first side surface is located has a first included angle α with the sunlight irradiation direction, and the angle range of the first included angle α is 75°≤α≤105°; when the louver structure is in the second state, the plane where the first side surface is located has a second included angle β with the sunlight irradiation direction, and the angle range of the second included angle β is -15°≤α≤15°.

[0020] A sunlight reflecting material layer is arranged on the first side surface of the louver structure; and / or, sunlight reflecting material is coated on the first side surface of the louver structure.

[0021] For the Trombe wall of the present invention, by arranging a louver structure between the glass structure and the wall, and enabling the louver structure to reflect sunlight or allow sunlight to pass through and irradiate the wall, the heating ability of sunlight on the wall can be controlled. In winter, the wall can absorb sunlight through the louver structure to increase the energy absorbed by the wall and improve the heating ability for the interior. In summer, the louver structure can reflect sunlight to reduce the energy absorbed by the wall and lower the heating ability for the interior, thereby solving the problem in the prior art that the wall still absorbs a large amount of heat in summer, resulting in too high indoor temperature, effectively improving the comfort of users. Moreover, by using a driving mechanism to automatically drive the louver structure based on the obtained ambient temperature, automatic adjustment is achieved, avoiding problems such as misoperation and forgetting to operate that may occur when users need to actively adjust, and further improving the user experience.

[0031] The following further describes the present invention in conjunction with embodiments, but is not limited to the content in the specification.

[0032] AsFigures 1 to 8 As shown in the figure, the present invention discloses a Trombe wall, comprising: a wall body 1; a glass structure 2, the glass structure 2 is arranged on the outer surface of the wall body 1, and there is a first spacing 3 between the glass structure 2 and the wall body 1. A first communication port is arranged at the upper part of the glass structure 2, and a second communication port is arranged at the lower part. The first spacing 3 is communicated with the outside through the first communication port and the second communication port; a louver structure 4, the louver structure 4 is arranged in the first spacing 3, and the louver structure 4 has a first state and a second state; when the louver structure 4 is in the first state, sunlight cannot irradiate the wall body 1 through the louver structure 4; when the louver structure 4 is in the second state, sunlight can penetrate the louver structure 4 and irradiate the wall body 1; a driving mechanism, the driving mechanism is arranged on the wall body 1 and / or the glass structure 2, and the driving mechanism is in transmission connection with the louver structure 4; the driving mechanism can obtain the ambient temperature at the location of the Trombe wall to drive the louver structure 4 to switch between the first state and the second state. By arranging the louver structure 4 between the glass structure 2 and the wall body 1, and enabling the louver structure 4 to reflect sunlight or allow sunlight to pass through and irradiate the wall body 1, the heating ability of sunlight on the wall body 1 can be controlled. As Figure 4 shown, in winter, the wall body 1 can absorb sunlight through the louver structure 4 to increase the energy absorbed by the wall body 1 and improve the heating ability for the interior. And as Figure 5 shown, in summer, the louver structure 4 can reflect sunlight to reduce the energy absorbed by the wall body 1 and lower the heating ability for the interior, thus solving the problem that the wall body 1 in the prior art still absorbs a large amount of heat in summer, resulting in too high indoor temperature, effectively improving the comfort of users. Moreover, by using the driving mechanism to obtain the ambient temperature to automatically drive the louver structure 4, automatic adjustment is realized, avoiding problems such as misoperation and forgetting to operate due to the need for users to actively adjust, and further improving the user experience.

[0033] As an implementation manner, the driving mechanism includes a bimetallic strip 5, the bimetallic strip 5 is disposed on the wall body 1 and / or the glass structure 2, and the bimetallic strip 5 is in transmission connection with the louver structure 4. The bimetallic strip 5 is a composite material composed of two or more metals or other materials with suitable properties. Due to the different thermal expansion coefficients of the component layers of the bimetallic strip 5, when the temperature changes, the deformation of the active layer is greater than that of the passive layer. As a result, the whole bimetallic strip 5 will bend towards the passive layer side, and then the curvature of this composite material changes to generate deformation. Utilizing the principle of deformation caused by such temperature changes, the bimetallic strip 5 can directly deform automatically according to the ambient temperature, and further drive the louver structure 4 to adjust between the first state and the second state. Specifically, during the process of changing from winter to summer, the ambient temperature gradually increases. At this time, the bimetallic strip 5 will deform with the change of temperature, thereby driving the louver structure 4 to gradually switch from the first state to the second state. And when changing from summer to winter, the ambient temperature gradually decreases. At this time, the bimetallic strip 5 will gradually return to its original shape with the change of temperature, thereby driving the louver structure 4 to gradually switch from the second state to the first state, thus achieving the purpose of automatically adjusting the louver structure 4, realizing the automatic adjustment of the Trombe wall, and improving the user experience.

[0034] In order to further improve the driving ability brought by the deformation of the bimetallic strip 5, the shape of the bimetallic strip 5 is a spiral shape, and the first end of the spiral shape is fixedly disposed on the wall body 1 and / or the glass structure 2, and the second end is in transmission connection with the louver structure 4. By setting the bimetallic strip 5 as a spiral shape, when the bimetallic strip 5 deforms, the torque generated by the bimetallic strip 5 is greater than the torque of the bimetallic strip 5 in the flattened state. Furthermore, it can ensure the driving effect on the louver structure 4, ensure the reliable switching of the louver structure 4 between the first state and the second state, and improve the structural reliability of the Trombe wall.

[0035] The driving mechanism further includes a first rotating shaft 61. The first rotating shaft 61 is rotatably disposed on the wall body 1. The bimetallic strip 5 is wound around the first rotating shaft 61, and the second end of the bimetallic strip 5 is connected to the first rotating shaft 61. The louver structure 4 is in transmission connection with the first rotating shaft 61, and the rotation of the first rotating shaft 61 can drive the louver structure 4 to rotate. By setting the first rotating shaft 61, it is convenient to install the bimetallic strip 5, and at the same time, it is also convenient to transmit the torque generated by the deformation of the bimetallic strip 5. The deformation of the bimetallic strip 5 can directly drive the first rotating shaft 61 to rotate, and then the rotation of the first rotating shaft 61 can be transmitted to the louver structure 4 through a transmission mechanism to adjust the louver structure 4.

[0036] To avoid an excessive thickness of the Trombe wall, the size of the first spacing 3 is made smaller. Therefore, the size of a single louver structure 4 is reduced, and the number of the louver structures 4 is multiple. All the louver structures 4 are arranged side by side within the first spacing 3, and all the louver structures 4 are in transmission connection with the driving mechanism. When the louver structure 4 is in the first state, in adjacent two layers of the louver structures 4, the shadow of the upper louver structure 4 at least partially lies on the lower louver structure 4, so as to ensure that sunlight cannot irradiate the wall body 1 through the louver structure 4. Most of the sunlight will be reflected by the glass structure 2, thereby reducing the sunlight absorption efficiency. At this time, the wall body 1 cannot receive sunlight irradiation and has a lower temperature. At the same time, the louver structure 4 reflects sunlight and also has a lower temperature. At this time, the heating capacity of the wall body 1 for the interior can be reduced, so that the indoor temperature is reduced compared with the prior art, and the comfort of the user is improved. When the louver structure 4 is in the second state, sunlight can irradiate the wall body 1 through the spacing between two adjacent louver structures 4. Sunlight can directly irradiate the wall body 1 to ensure the sunlight absorption efficiency and ensure the temperature of the wall body 1 and the heating capacity of the wall body 1 for the interior.

[0037] To ensure the reliability of the switching between the first state and the second state of the louver structure 4, a second rotating shaft 62 is provided on the louver structure 4. The louver structure 4 is rotatably arranged within the first spacing 3 through the second rotating shaft 62. By rotating the second rotating shaft 62, the adjustment of the louver structure 4 can be realized. At this time, the first rotating shaft 61 can directly drive the second rotating shaft 62 to rotate only through transmission means such as cables and chains, and further achieve the purpose of driving the louver structure 4 by the bimetallic strip 5. The second rotating shaft 62 can also be a virtual shaft. The first rotating shaft 61 can directly drive the louver structure 4 and make the louver structure 4 rotate along its corresponding second rotating shaft 62.

[0038] Wherein, the axis of the second rotating shaft 62 is parallel to the horizontal plane. At this time, the weights of the louver structures 4 distributed on both sides of the second rotating shaft 62 are basically the same. When the driving mechanism drives the louver structure 4 to rotate, only the inertia of the louver structure 4 needs to be overcome, thereby reducing the torque required to be provided by the driving mechanism and improving the adjustment reliability of the bimetallic strip 5 for the louver structure 4.

[0039] Preferably, all the louver structures 4 are arranged side by side in the vertical direction. At this time, the second rotating shafts 62 of the louver structures 4 can be parallel to the first rotating shaft 61, which is convenient for the first rotating shaft 61 to drive the second rotating shaft 62 and improves the adjustment reliability of the bimetallic strip 5 for the louver structure 4.

[0040] Such as Figure 1As shown, the Trombe wall further includes a driving disc and a pull rod. There is a transmission connection between the first rotating shaft 61 and the driving disc. The pull rod is hinged to the driving disc, and there is a second distance between the end of the pull rod and the rotating shaft of the driving disc. All the louver structures 4 are connected to the pull rod. The first rotating shaft 61 drives the driving disc to rotate, thereby controlling the pull rod to move in an arc. The pull rod then drives all the louver structures 4 to move in an arc, enabling the louver structures 4 to rotate along the second rotating shaft 62, achieving the purpose of adjusting the louver structures 4.

[0041] Preferably, the number of pull rods is two, and the two pull rods are symmetrically distributed on both sides of the driving disc. At this time, the two pull rods can connect different positions of the louver structure 4, thereby further improving the driving reliability of the driving disc for the louver structure 4.

[0042] The cross-section of the louver structure 4 is in the shape of a "one", and the "one" shape has a first side 41 that can reflect sunlight. When the louver structure 4 is in the first state, the first side 41 faces the glass structure 2; when the louver structure 4 is in the second state, the first side 41 faces the wall 1. By rotating the "one" shape, the louver structure 4 can block and reflect sunlight and allow sunlight to pass through using the spacing, thereby ensuring the automatic adjustment of the Trombe wall and improving the user experience.

[0043] As Figure 3 shown, the two pull rods are respectively connected to the left and right parts of the "one" shape. When the driving disc rotates, one pull rod will move relatively downward, and the other pull rod will move relatively upward, thereby achieving the purpose of rotating the "one" shape along its center and improving the driving reliability of the driving disc for the louver structure 4.

[0044] Preferably, when the louver structure 4 is in the first state, the plane where the first side 41 is located has a first included angle α with the sunlight irradiation direction, and the angle range of the first included angle α is 75° ≤ α ≤ 105°. At this time, the first side 41 is basically perpendicular to the sunlight irradiation direction, thereby ensuring the reflection effect of sunlight and achieving the purpose of preventing the wall 1 from being heated by sunlight irradiation.

[0045] When the louver structure 4 is in the second state, the plane where the first side 41 is located has a second included angle β with the sunlight irradiation direction, and the angle range of the second included angle β is -15° ≤ α ≤ 15°. At this time, the louver structure 4 is basically parallel to the sunlight irradiation direction, and sunlight can pass through the louver structure 4 from the spacing between the louver structures 4 and irradiate the wall 1, thereby realizing the heating of the wall 1 and ensuring the temperature of the wall 1 and the heating ability of the wall 1 for the interior.

[0046] A solar light reflecting material layer is provided on the first side 41 of the louver structure 4. By providing a solar light absorbing material layer, the absorption efficiency of sunlight and the ability of the Trombe wall to obtain solar energy are reduced, thereby reducing the heating capacity of the room and avoiding the problem of over-high indoor temperature in summer.

[0047] Alternatively, a solar light reflecting material is coated on the first side 41 of the louver structure 4, and a solar light absorbing material is directly coated on the first side 41 to reduce the absorption efficiency of sunlight and the ability of the Trombe wall to obtain solar energy, thereby reducing the heating capacity of the room and avoiding the problem of over-high indoor temperature in summer.

[0048] A third communication port and a fourth communication port are provided on the wall 1. The third communication port is located above the fourth communication port, and the third communication port is at the same height as the first communication port, and the fourth communication port is at the same height as the second communication port. The first communication port and the second communication port can be used to allow outdoor air to enter the first spacing 3. At the same time, the third communication port and the fourth communication port can connect the first spacing 3 with the room. At this time, the indoor and outdoor can perform gas exchange through the first spacing 3. In winter, the louver structure 4 absorbs sunlight and generates heat in the first spacing 3. The outdoor air flows through the first spacing 3 and is heated by the louver structure 4, thereby reducing the problem that cold air flows into the room and affects the indoor temperature.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
