Technical Field

[0001] This invention relates to the field of building construction technology, specifically a ventilation and air exchange device for indoor air purification in buildings. Background Technology

[0002] During construction, temporary prefabricated houses are often needed for use as offices, dormitories, warehouses, etc. In order to improve the reusability of prefabricated houses, mobile prefabricated houses have emerged. Mobile prefabricated houses are constructed with light steel as the frame and sandwich panels as the enclosure material. However, there are some shortcomings in the wall structure of mobile prefabricated houses on the market. The traditional installation and disassembly methods are inconvenient and easily cause damage and scrapping during the installation and disassembly process. In addition, the traditional wall structure of mobile prefabricated houses is relatively simple, with insufficient protection and practicality, and low thermal insulation performance.

[0003] Therefore, those skilled in the art have provided a near-zero-consumption prefabricated building wall structure to solve the problems mentioned in the background art. Summary of the Invention

The positioning base is anchored to the foundation, and an I-shaped clamping plate is fixed above the positioning base. A sealing gasket is adhered to the inner side of the I-shaped clamping plate, and the two I-shaped clamping plates are respectively engaged with the two sides of the prefabricated wall through sealing gaskets. The prefabricated wall includes a water tank, an outer wall, an inner wall, an insulation board, and interior panels arranged sequentially from left to right. A cavity 1 is provided between the exterior wall and the interior wall, and the exterior wall and the interior wall are connected together by horizontally spaced connecting plates. The connecting plates divide the cavity 1 into multiple unit spaces 1, and each unit space 1 is equipped with a vacuum component to reduce heat transfer. A cavity 2 is provided between the insulation board and the interior panel, and the insulation board and the interior panel are connected together by horizontally spaced partitions. The partitions divide the cavity 2 into multiple unit spaces 2, and each unit space 2 is filled with phase change material.

[0005] Furthermore, as a preferred embodiment, the vacuum assembly includes a sealing capsule and a support frame. The outer surface of the sealing capsule is attached to the inner wall of the unit space, and the inner surface of the sealing capsule is supported and fixed on the support frame. The size of the support frame matches the size of the unit space.

[0006] Furthermore, as a preferred embodiment, each of the two unit spaces is filled with 70% phase change material, which is a solid-liquid eutectic phase change material with a solid-liquid eutectic temperature of 23.3 degrees Celsius. The phase change material is heat-storaged using a water tank and water pipe assembly.

[0007] Furthermore, as a preferred embodiment, the water tank and water pipe assembly includes a water tank, a first water outlet pipe, and a second water outlet pipe. The water tank is detachably fixed to the outside of the outer wall. The outer wall of the water tank is coated with a heat-absorbing material. A floating plate is slidably disposed in the water tank. Sealing plates are fixed at both the upper and lower ends of the water tank to limit the movement of the floating plate. A first water inlet pipe and a second water inlet pipe are embedded and connected to the water tank from the outside. The first water inlet pipe and the second water inlet pipe are respectively located near the sealing plates at the upper and lower ends. The water tank is also connected to a first water outlet pipe and a second water outlet pipe.

[0008] Furthermore, as a preferred embodiment, the first water outlet pipe is located near the first water inlet pipe, and the first water outlet pipe passes through the connecting plate, the inner wall, and the insulation board in sequence to enter the second unit space, and extends out of the interior panel from top to bottom through multiple second unit spaces.

[0009] Furthermore, as a preferred embodiment, both the first and second water outlets in each of the second unit spaces are disc-shaped, thereby increasing their contact area with the phase change material.

[0010] Furthermore, as a preferred embodiment, the inner wall is made of foamed cement and has multiple horizontally arranged hollow studs fixed inside. The hollow studs extend out of the inner wall along their axial direction, and the number of hollow studs is the same as the number of sealing bladders.

[0011] Furthermore, as a preferred embodiment, the inner side of the I-shaped card plate is provided with multiple sets of positioning through holes corresponding to the hollow studs, so that the hollow studs can pass through them and be fixedly connected to the nuts.

[0013] Furthermore, as a preferred embodiment, the inner wall is provided with multiple X-shaped reinforcing ribs arranged at intervals.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The near-zero consumption prefabricated house wall structure of the present invention can be reused. It not only achieves good thermal insulation, but also has a good heat storage function. At the same time, it can exchange the heat in the phase change material with the indoor space, which greatly improves the comfort of the room. The phase change material uses a water tank and water pipe assembly for heat storage. The water in the tank gradually heats up under the sunlight. During domestic water use, hot water flows out through water outlet one or water outlet two, thereby heating and storing energy in the phase change material.

[0016] 2. In this invention, a vacuum assembly is provided in each of the unit spaces to reduce heat propagation. A connector is connected to the sealed bladder, which passes through the inner wall and is connected to the adjacent hollow stud. The two ends of the hollow stud are detachably sealed with plugs, which facilitates regular inspection of the vacuum level in the sealed bladder and timely handling. Attached Figure Description

The partitions 11 divide the cavity 2 into multiple unit spaces 2, and each unit space 2 is filled with phase change material.

[0024] In this embodiment, the vacuum assembly includes a sealing capsule 18 and a support frame 19. The outer surface of the sealing capsule 18 is attached to the inner wall of the unit space 1, and the inner surface of the sealing capsule 18 is supported and fixed on the support frame 19.

[0025] In a preferred embodiment, each of the two unit spaces is filled with 70% phase change material, which is a solid-liquid eutectic phase change material with a solid-liquid eutectic temperature of 23.3 degrees Celsius. The phase change material is heat-storaged using a water tank and water pipe assembly. Furthermore, the phase change material is first encapsulated and modified to prevent liquid leakage. During encapsulation, small spherical or rod-shaped particles are encapsulated in a thin polymer film to form phase change capsules. Generally, microencapsulation technology or nanocomposite technology is used to encapsulate the phase change material into energy microspheres.

[0026] In this embodiment, the water tank and water pipe assembly includes a water tank 7, a first water outlet pipe 20, and a second water outlet pipe 21. The water tank 7 is detachably fixed to the outside of the outer wall 8. The outer wall of the water tank is coated with a heat-absorbing material. A floating plate 15 is slidably arranged in the water tank 7. Sealing plates 16 are fixed at both the upper and lower ends of the water tank 7 to limit the floating plate 15. A first water inlet pipe 13 and a second water inlet pipe 14 are embedded and connected to the water tank 7 from the outside. The first water inlet pipe 13 and the second water inlet pipe 14 are respectively located near the sealing plates 16 at the upper and lower ends. The water tank 7 is also connected to the first water outlet pipe 20 and the second water outlet pipe 21. It should be noted that valves are provided on the first water inlet pipe, the second water inlet pipe, the first water outlet pipe, and the second water outlet pipe.

[0027] In this embodiment, the first water outlet pipe 20 is located near the first water inlet pipe 13, and the first water outlet pipe 20 passes through the connecting plate 17, the inner wall 9, and the insulation board 12 in sequence to enter the second unit space, and extends out of the interior panel 10 from top to bottom through multiple second unit spaces.

[0028] In this embodiment, both the first and second water outlet pipes in each of the second unit spaces are disc-shaped, thereby increasing their contact area with the phase change material.

[0029] In this embodiment, the inner wall 9 is made of foamed cement and has multiple horizontally arranged hollow studs 22 fixed inside. The hollow studs 22 extend out of the inner wall 9 along their axial direction, and the number of hollow studs 22 is the same as the number of sealing bladders 18.

[0031] In this embodiment, the sealing bladder 18 is connected to a connector, which passes through the inner wall 9 and is connected to the adjacent hollow stud 22. The two ends of the hollow stud 22 are detachably sealed with plugs, which facilitates regular inspection of the vacuum level in the sealing bladder 18 and timely handling.

[0032] In this embodiment, multiple X-shaped reinforcing ribs 23 are arranged at intervals in the inner wall 9.

[0033] The near-zero-consumption prefabricated house wall structure of this invention not only achieves excellent thermal insulation but also has good heat storage capabilities. Simultaneously, it can exchange heat from the phase change material with the interior space, greatly improving indoor comfort. In specific implementation, the initial state is as follows: Figure 3 As shown, the water tank 7 is filled with water and gradually heats up under sunlight. During domestic water use, the valves on the inlet pipe 14 and the outlet pipe 20 are opened. At this time, the valves on the inlet pipe 1 and the outlet pipe 2 are closed, and hot water flows out through the outlet pipe 20, thereby heating and storing energy for the phase change material. During use, the floating plate 15 slowly rises, and water is slowly added below the floating plate 15. When the water above the floating plate 15 is used up, the water below it can be used. Preferably, the water tank 7 has enough storage for one day's use.
