Description

Technical Field

[0001] The present application relates to the technical field of building components, and in particular to a flip-type wall and a method for using the flip-type wall. Background Art

[0002] Buildings with climate adaptability are the focus of future building energy conservation work. In winter, the outdoor temperature is low, and buildings need good insulation to reduce indoor heat loss; in summer, the outdoor temperature is high, the solar radiation is strong, and the energy consumption required for indoor cooling is high. The patent with announcement number CN104018587B proposes a phase change energy storage rotating wall. This technology can use the phase change layer on the wall and the rotation of the wall to store energy in the phase change layer using the outdoor environment. The phase change layer releases energy after rotating into the room, thereby providing free cooling or heat for the room. In summer, the phase change material side is rotated to the outer surface of the building at night to store cold using the lower temperature at night in summer; during the day, the phase change material side is rotated to the inner surface of the building, and the cold storage of the phase change material at night is released indoors. In winter, the phase change material side is rotated to the outer surface of the building during the day to store heat using the higher outdoor temperature during the winter daytime; at night, the phase change material side is rotated to the inner surface of the building, and the heat storage of the phase change material during the day is released indoors.

[0003] The existing technology mainly has the following shortcomings:

[0004] 1. Phase change materials have the problem of heat storage and heat release hysteresis, and the frequent flipping of the wall further amplifies this problem. Taking summer as an example, the wall uses phase change materials to discharge heat to the outside at night in summer to store cold, but after the phase change material is flipped to the inside of the building during the day, due to the problem of heat storage and release hysteresis of the phase change material, the cold cannot be quickly dissipated to the room, and even before the cold is fully provided to the room, the wall has been flipped at night. At the same time, the wall uses phase change materials to store heat on the outside of the wall during the day in winter. Although the daytime temperature in winter is higher than at night, for most areas that need heating, the outdoor temperature during the day in winter is still very low. It is difficult to directly use phase change materials to store heat during the day in winter and the operating efficiency is low.

[0005] 2. The existing technology adopts a flipping method with the middle of the wall as the rotation axis. The wall flipping process needs to form a cylindrical space with the rotation axis as the center and the wall width as the diameter. This flipping method will occupy a large amount of indoor space and affect the space utilization efficiency inside the room.

[0006] 3. In winter and summer, the wall rotates inward and outward on a daily basis, and the number of wall rotations is relatively high. Long-term and frequent wall flipping may have a certain impact on the safety and stability of the wall. In addition, each wall flipping process is equivalent to ventilating the room. In summer, a large amount of high-temperature outdoor air can directly enter the room, while in winter, a large amount of low-temperature outdoor air can also directly enter the room. Therefore, too frequent daily wall flipping may have opposite negative effects on the room's summer cooling and winter heating. Summary of the invention

[0007] In view of the problems existing in the prior art, the present application provides a flip wall and a method for using the flip wall.

[0008] The present application provides a flip-type wall, the flip-type wall comprising:

[0009] Wall body;

[0010] a rotating shaft connected to the wall body and located at one end of the wall body in the left-right direction, so that the wall body can rotate around the central axis of the rotating shaft; and

[0011] The guide rail is used to be fixedly connected to the load-bearing structure, and the rotating shaft is connected to the guide rail, so that the wall body can move along the guide rail and rotate relative to the guide rail.

[0012] In at least one embodiment, the guide rail is U-shaped, comprising two arms extending along the thickness direction of the wall body and a bottom connecting the two arms, the length of the arm is greater than 1 / 2 of the thickness of the wall body, and the length of the bottom is greater than 80% of the length of the wall body in the left and right directions.

[0013] In at least one embodiment, an extension direction of the arm portion is perpendicular to an extension direction of the bottom portion.

[0014] In at least one embodiment, the wall body comprises:

[0015] Wall structure layer;

[0016] A material with high solar radiation absorption rate located on one side of the wall structure layer in the thickness direction,

[0017] A material with high visible light reflectivity is located on the other side of the wall structure layer in the thickness direction.

[0018] In at least one embodiment, the high visible light reflectance material has a high long-wave emissivity.

[0019] In at least one embodiment, the high visible light reflectance material is a radiative cooling material.

[0020] In at least one embodiment, the high solar radiation absorptivity material comprises a solar photovoltaic / thermal panel.

[0021] In at least one embodiment, the flip-type wall further includes a heat-insulating layer, and the heat-insulating layer is located between the wall structure layer and the high visible light reflectivity material.

[0022] In at least one embodiment, in the left-right direction of the wall body, a ratio of a distance between the rotation axis and one end of the wall body to a distance between the rotation axis and the other end of the wall body is less than 3:7.

[0023] The present application provides a method for using a flip-type wall, wherein the flip-type wall is the flip-type wall disclosed in the present application, and the method for using the flip-type wall comprises:

[0024] The wall body is turned inside out by moving and rotating the rotating shaft relative to the guide rail.

[0025] By adopting the above technical solution, one aspect of the present application proposes a flip-type wall. By setting the rotating shaft at one end of the wall body in the left and right directions, the wall body can be flipped outward, reducing the problem of occupying too much indoor space when the wall body flips.

[0026] Another aspect of the present application is to propose a flip-type wall. By arranging heat storage materials and heat dissipation materials on both sides of the flip-type wall, the wall can have two stable thermodynamic states before and after flipping. This solves the hysteresis problem of phase change materials and improves the heat storage demand, especially in winter.

[0027] Furthermore, the present application saves indoor space and improves the utilization rate of the interior space of the building through the structural design of the rotating shaft and the track on the wall and the outward flipping form of the wall.

[0028] By adopting the above technical solution, the present application proposes a method for using a flip-type wall. The method can (but is not limited to) flip the wall in units of seasons. By setting heat storage and heat dissipation materials on both sides of the wall, the technical effect of heat storage in winter and heat dissipation in summer is achieved, thereby reducing the heating and cooling energy consumption of the building throughout the year, achieving the purpose of energy saving and emission reduction.

[0039] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0040] This application proposes a flip-type wall, which does not participate in load-bearing and can be directly used as an external protective wall. Figure 1 According to the present application, the flip-type wall includes a wall body, a rotating shaft 5 and a guide rail 6.

[0041] like Figure 1 As shown, the wall body includes a wall structure layer 2, and the two sides of the wall structure layer 2 are provided with heat storage and heat removal materials respectively. (It can be understood that the heat storage material and the heat removal material are not on the same side) The heat storage material can be a material 1 with high solar radiation absorption rate, which is located on one side in the thickness direction of the wall body. The heat removal material can be a material 4 with high visible light reflectivity, which is located on the other side in the thickness direction of the wall body. It can be understood that the heat storage material or the heat removal material can be located outdoors by flipping the wall.

[0042] The material 1 with high solar radiation absorption rate may specifically include, for example, PV / T (solar photovoltaic / thermal) panels, etc., which can increase the temperature of the building exterior wall by absorbing solar radiation and further reduce the indoor heating load. Among them, high solar radiation absorption rate may refer to a solar radiation absorption rate greater than 0.9.

[0043] The high visible light reflectivity material 4 may specifically include glass, silver-plated coating, and aluminum-plated coating. By reflecting solar radiation, the solar radiation heat gain of the building can be reduced. Preferably, the high visible light reflectivity material 4 also includes a characteristic of high long-wave emissivity, such as using a radiation cooling material, which can reduce the solar radiation heat gain of the building by reflecting solar radiation, while further reducing the indoor heat by utilizing the cold radiation of the sky, thereby reducing the indoor air conditioning refrigeration load. Among them, high visible light reflectivity can refer to a visible light reflectivity greater than 0.9, and high long-wave emissivity can refer to a long-wave radiation emissivity greater than 0.8. Long wave refers to sunlight with a frequency of 30 to 300 kHz and a wavelength of 1000 to 10000 m.

[0044] Preferably, a heat-insulating layer 3 may be provided between the wall structure layer 2 and the high visible light reflectivity material 4. The heat-insulating layer 3 may be, for example, a flame-retardant polystyrene foam board, or an extruded board, a polyurethane board, rock wool, or the like.

[0045] For winter conditions, Figure 2 As shown, by flipping the wall body so that the material 1 with high solar radiation absorption rate is located on the outer surface of the building, that is, facing the outdoor O, a stable thermodynamic state can be formed to continuously store heat for the building. On the basis of meeting the basic requirements of winter wall insulation, the heat provided by renewable resources is fully utilized. At the same time, the insulation layer 3 is located inside the wall structure layer 2, which helps to increase the influence of the wall on the thermal inertia of the room temperature, reduce the heat dissipation of the room, and help to ensure the thermal stability of the room under the condition of no solar energy at night in winter.

[0046] For summer conditions, Figure 3 As shown, by flipping the wall body so that the high visible light reflectance material 4 is located on the outer surface of the building, that is, facing the outside O, a stable thermodynamic state can be formed to continuously discharge heat from the building. At the same time, the insulation layer 3 is located outside the wall structure layer 2, which helps to reduce the impact of the wall body on the thermal inertia of the indoor temperature I, thereby reducing the impact on the heat dissipation of the room.

[0047] For transitional seasons or other periods where ventilation is required, the flip wall can be fully utilized for natural ventilation. Figure 4a , Figure 4b As shown, for example, by rotating the wall body to a certain angle so that the wall remains in an open state and an opening is formed, the ventilated opening area of ​​the room can be increased, and the indoor heat can be taken away with the help of the lower outdoor temperature, thereby providing a more comfortable environment for the indoor room without consuming additional energy.

[0048] Here, for the purpose of convenience of explanation, the thickness direction (inside-outside direction) of the wall body when the flip wall is closed is taken as the front-to-back direction, and the direction perpendicular to both the front-to-back direction and the up-down direction is taken as the left-to-right direction. The rotating shaft 5 can be located at one end of the wall body in the left-to-right direction. Preferably, in the left-to-right direction of the wall body, the ratio of the distance between the rotating shaft 5 and one end of the wall body to the distance between the rotating shaft 5 and the other end of the wall body can be less than 3:7, more preferably, less than 2:8, and even more preferably, less than 1:9. The rotating shaft 5 can be fixedly connected to the wall body for rotation of the wall body. Preferably, as Figure 1 As shown, the rotating shaft 5 in this embodiment is located at the corner of the wall body.

[0049] like Figures 5a to 5f As shown, the flip-type wall can be flipped to the outside of the building (it can be understood that flipping outward means that when the wall body flips, the part of the wall body located outside the building is more than the part located inside the building). The outside flipping form reduces the indoor space occupied by the flipping process, which can improve the utilization rate of the internal space of the building.

[0050] The guide rail 6 can be fixedly connected to the load-bearing structure of the building, for example, the guide rail 6 is fixed to the upper and lower floors (similar to the way of fixing the outer wall panels of the assembled building). The rotating shaft 5 can slide and rotate in the guide rail 6, thereby satisfying the movement of the wall body.

[0051] It is understandable that a motor or other device can be used to control the rotation angle and movement (sliding) distance of the rotating shaft 5, thereby satisfying the movement and rotation process of the flip wall and maintaining a closed or non-closed state.

[0052] In this embodiment, the guide rail 6 is U-shaped, and includes two arms 61, 62 extending in the front-back direction and a bottom 63 connecting the two arms 61, 62. The bottom 63 can extend in the left-right direction. The length of the arms 61, 62 can be approximately equal to the thickness of the wall body. In one example, the length of the arms 61, 62 is greater than 1 / 2 of the thickness of the wall body. The length of the bottom 63 can be approximately equal to the length of the wall body in the left-right direction. In one example, the length of the bottom 63 can be greater than 80% of the length of the wall body in the left-right direction.

[0053] The extension direction of the arms 61, 62 may be perpendicular to the extension direction of the bottom 63. Here, the arms 61, 62 being perpendicular to the bottom 63 does not exclude the provision of a corner such as a circular arc transition at the connection portion of the arms 61, 62 and the bottom 63.

[0054] The present application also proposes a method for using a flip-type wall, wherein heat storage and heat dissipation materials are fixed on both sides of the flip-type wall, and the wall can be flipped in units of seasons (but not limited to). In winter, the heat storage material side of the flip-type wall faces outward, and in summer, the heat dissipation material side of the flip-type wall faces outward.

[0055] It can be understood that the flip wall can be the flip wall mentioned in the above embodiment. The material 1 with high solar radiation absorption rate is fixed on one side of the wall structure layer 2 as a heat storage material; the material 4 with high visible light reflectivity is fixed on the other side of the wall structure layer 2 as a heat dissipation material.

[0056] It can be understood that the flipping mode of the flip wall can be: in summer, the material 4 with high visible light reflectivity is located on the outer surface of the building; in winter, the material 1 with high solar radiation absorption rate is located on the outer surface of the building; and in transitional seasons and other periods requiring ventilation, the flip wall can remain in a non-closed state to form an opening.

[0057] Preferably, the flip-type wall is flipped toward the outside of the building, which improves the flipping method of the prior art using the middle of the wall as the axis of rotation, can reduce the large amount of indoor space occupied by the flipping process, and improve the utilization rate of the building's internal space.

[0058] by Figures 5a to 5f Taking the flipping process shown as an example, the present application shows the external flipping process of a group of flipping walls (specifically flipping walls 11, 12, 13, 14). The specific translation and rotation directions of the walls are shown by arrows.

[0059] Figure 5a Schematic diagram of the initial (closed) working condition of the wall.

[0060] like Figure 5b As shown, after the flipping process is started, the flipping walls 12 and 14 move outward (translationally) by the rotation shaft 5 moving outward along the arm 61 or 62 of the guide rail 6.

[0061] like Figure 5c As shown, the outwardly moved flip-type walls 12, 14 are transformed into a 90° state (open state) by the rotation shaft 5 moving horizontally along the bottom 63 of the guide rail 6 and rotating 90° clockwise.

[0062] like Figure 5d As shown, the remaining walls (flip walls 11, 13) are similarly transformed into a 90° state (open state) by the shaft 5 moving outwards along the guide rail 6, moving horizontally and rotating 90° clockwise.

[0063] like Figure 5e As shown, the flip-type walls 12 and 14 continue to move horizontally along the guide rail 6 through the rotating shaft 5 and rotate 90° clockwise, and then move inward along the guide rail 6 to transform into a 180° state (closed state).

[0064] like Figure 5f As shown, the remaining walls (flipping walls 11, 13) are similarly moved horizontally along the guide rail 6 and rotated 90° clockwise, and then moved inward along the guide rail 6 to turn into a 180° state (closed state), thus completing a wall flip. It can be understood that when the wall needs to be flipped during the season change, it can return along the original path.

[0065] During transitional seasons or other periods where ventilation is required, you can move only some walls, or all walls. For example, when moving all walls, all walls are rotated and moved to the same position as above. Figure 5d Then, the whole is rotated counterclockwise, for example, by 45°, to achieve Figure 4a , Figure 4b Status shown.

[0066] The above scheme is only a representative and preferred example. Other similar schemes, such as the situation of more modules that can be inferred from the above scheme, the position of each component of the module in a non-moving state, and similar rotation angles, displacements and operation sequences during movement, should all be considered as the protection scope of this application.

[0067] The walls can be flipped and switched on a seasonal basis, which greatly reduces the frequency of wall flipping and the impact of frequent wall flipping on wall safety and stability. At the same time, it reduces the ventilation of the room during the flipping process, thereby reducing the negative impact of too frequent wall flipping on the room's summer cooling and winter heating, reducing the building's cooling and heating energy consumption throughout the year, and achieving the goal of energy conservation and emission reduction.

[0068] The above is a preferred embodiment of the present application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
