[0001] This invention relates to the field of building technology, specifically to a temporary prefabricated building with integrated ventilation for curtain walls and roofs. Background Technology

[0002] Temporary prefabricated houses (such as container houses and mobile homes) are currently widely used in construction sites, disaster relief, and other scenarios. However, these types of buildings typically suffer from poor thermal insulation and ventilation. Especially in summer, direct sunlight causes the interior temperature of these prefabricated houses to rise sharply, resulting in low living comfort and significant energy consumption due to reliance on air conditioning for cooling.

[0003] While some prefabricated houses utilize thickened insulation layers in existing technologies, this does not solve the ventilation problem. Furthermore, traditional prefabricated houses have a limited structural form, lack targeted passive energy-saving designs, and are complex to assemble on-site, making rapid construction and disassembly for reuse difficult.

Utilizing the principle of thermal pressure ventilation (chimney effect), when the outside air is heated or the photovoltaic panels generate heat, the hot air rises along the air ducts and is discharged through regulating valves, simultaneously carrying away heat from the prefabricated building envelope, significantly reducing indoor temperature and reducing air conditioning energy consumption. Furthermore, this structure achieves an organic combination of building-integrated photovoltaics (BIPV) and passive ventilation. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Those skilled in the art will understand that, in this specification, the term "comprising" is an open-ended expression, meaning that the stated feature is present but other features are excluded. Directional terms such as "upper," "lower," "left," and "right" refer to exemplary directions based on the accompanying drawings. Features specified as "first" or "second" implicitly include one or more of that feature. Singular expressions can also be used in plural forms. "Multiple" means two or more. The terms "installed," "connected," and "linked" can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection via an intermediate medium, and it can be a connection within two components. Furthermore, "linked" can include wireless connections.

[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a temporary prefabricated building with integrated ventilation of curtain wall and roof, thereby solving the technical problems of poor heat insulation and ventilation performance and high energy consumption of existing temporary prefabricated buildings.

[0022] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: like Figure 1 As shown, this embodiment provides a temporary prefabricated building with integrated ventilation for curtain wall and roof, the main body of which includes prefabricated building unit 100, curtain wall unit 200, curtain wall top cover unit 300 and photovoltaic roof unit 400.

[0023] The prefabricated unit 100 serves as the core space for living or working, employing a standard box-type structure. Curtain wall units 200 are installed and fixed to the sun-facing side or both sides of the prefabricated unit 100, forming a vertical air duct 230 between the inner side of the curtain wall and the outer wall of the prefabricated unit. Windows 240 are provided on the outer facade of the curtain wall corresponding to this vertical air duct 230, serving both as lighting and part of the ventilation path.

[0024] A curtain wall top cover unit 300 is installed on top of the curtain wall unit 200. Inside the top cover unit is a hollow horizontal air duct 310. The lower end of the horizontal air duct 310 directly connects to the vertical air duct 230, serving to deflect airflow. The photovoltaic roof unit 400 is mounted above the prefabricated house unit 100, forming a mezzanine space of a certain height between it and the prefabricated house roof frame; this space serves as a buffer air duct 410. The lateral outlet of the horizontal air duct 310 connects to the beginning of the buffer air duct 410. At the end of the buffer air duct 410, i.e., the end furthest from the curtain wall, a regulating valve 420 is installed to control the opening, closing, and size of the air outlet.

[0025] Working Principle: This embodiment utilizes the "chimney effect" and the "thermal pressure principle." In summer, solar radiation irradiates the curtain wall unit 200 and the photovoltaic roof unit 400. The air in the vertical air duct 230 and buffer air duct 410 becomes less dense after being heated, generating upward buoyancy. The hot air rises along the vertical air duct 230, passes through the horizontal air duct 310 of the curtain wall roof unit 300, enters the buffer air duct 410, and is finally discharged from the opened regulating valve 420. This process creates negative pressure within the air ducts, continuously drawing in cooler outdoor air from the windows at the bottom of the curtain wall, forming a continuous airflow circulation. This circulation removes the heat accumulated on the exterior of the prefabricated building and blocks heat transfer to the interior of the prefabricated building unit 100. A complete integrated ventilation path is constructed, achieving fully passive natural cooling and effectively reducing the air conditioning energy consumption of the temporary prefabricated building in hot weather.

[0026] In addition, the photovoltaic roof unit 400, as an additional roof structure, can reduce the direct effect of solar radiation on the roof of the prefabricated house unit 100, lower the temperature of the roof and ceiling, reduce the heat gain from human body heat radiation, and thus improve indoor thermal comfort. The buffer air duct 410 formed between the photovoltaic roof and the prefabricated house roof can reduce the heat entering the room through the roof, reduce the air conditioning load, and achieve energy-saving effect.

[0027] During winter operation, the regulating valve 420 at the roof's end is closed. A relatively enclosed space is formed within the buffer duct 410, horizontal duct 310, and vertical duct 230. Under solar radiation, the air temperature inside the photovoltaic roof unit 400 and curtain wall unit 200 rises, thus forming an air buffer layer on the roof and corridor area of ​​the prefabricated building unit 100. This improves the thermal environment of the corridor area; furthermore, the increased air temperature within the roof's air gaps helps raise the roof and ceiling temperature of the prefabricated building, reducing radiative heat loss from people and minimizing heat loss through the roof, thereby reducing the air conditioning load and achieving energy savings.

[0028] To facilitate transportation and rapid on-site assembly, this embodiment employs a modular design for the aforementioned structure. The curtain wall unit 200, curtain wall roof unit 300, and photovoltaic roof unit 400 are all assembled from standard modular prefabricated components 500. Each modular prefabricated component 500 mainly includes a base frame, columns 520, and a top frame. Both the base frame and the top frame are designed as rectangular frame structures with high load-bearing capacity. The columns 520 are vertically installed, with both ends bolted to the corners of the top frame and base frame, respectively.

[0029] By using a standardized slab-column system, complex building structures are broken down into mass-producible modular units. During on-site construction, each module simply needs to be hoisted into place and bolted together. This significantly improves construction efficiency, reduces installation difficulty, and facilitates transportation and relocation after dismantling the prefabricated buildings.

[0030] like Figures 2A-2D As shown, Figure 2A For the overall picture, Figure 2B and Figure 2C This is a magnified view of the port. Figure 2D This is an enlarged view of the column. This embodiment details the specific structure of the curtain wall unit 200. The curtain wall unit 200 is divided into two layers in the height direction, with a first curtain wall 210 and a second curtain wall 220 connected sequentially from bottom to top. Both layers of curtain walls are assembled using the aforementioned modular prefabricated components 500.

[0031] The first curtain wall 210, located on the ground floor, uses a closed base frame 511, meaning the bottom is not airtight; while the base frame of the second curtain wall 220, located on the second floor, is replaced with a ventilated base frame 512. Both the first and second curtain walls 210 and 220 use hollow, open top frames 531 to ensure unobstructed upward airflow. The windows 240 are not directly perforated in the panels, but are fitted into recessed frames formed by columns 520, base frames, and top frames. During installation, clips are used to secure the window frames into the recesses, and sealant is applied to the joints for fixation and waterproofing.

[0032] Outside air enters the interiors of the first curtain wall 210 and the second curtain wall 220 through windows. Air in the first curtain wall 210 passes through the opening at the top of the first curtain wall 210 and the ventilation frame at the bottom of the second curtain wall 220, mixing with the air. It then flows upwards through the opening at the top of the second curtain wall 220 and along the vertical air duct 230. The recessed installation of the windows 240 utilizes the structural slots within the frame itself. This recessed installation simplifies the node construction and ensures water tightness and air tightness.

[0033] This embodiment describes in detail the material hierarchy of the base frame. The enclosed base frame 511 is constructed as follows: the foundation is a metal frame structure 540, on which a multi-layer composite floor 550 is laid. The composite floor 550, from bottom to top, consists of: cement fiberboard (providing strength and moisture resistance), water-based floor adhesive (for bonding), and linoleum (a wear-resistant finish). This structure allows the base frame within the curtain wall to effectively form a maintenance access floor that allows personnel to walk through.

[0034] The ventilation base frame 512 is constructed as follows: it also includes a frame structure 540 and the aforementioned multi-layer composite floor 550, but several ventilation openings 551 are opened at specific locations on the composite floor 550 to introduce air.

[0035] The composite floor layer provides sufficient load-bearing capacity and wear resistance, allowing the interior of the curtain wall to function not only as an air duct but also as a corridor. Ventilation vent 551 combines structural load-bearing with ventilation, improving space utilization and offering excellent material durability.

[0036] like Figure 3 As shown in the figure. This embodiment describes the specific structure of the curtain wall roof unit 300. Its base frame is an open base frame 513, which communicates with the curtain wall unit 200 below; its top frame is a solid closed top frame 532, used for wind and rain protection. Ventilation louvers 320 are installed between the columns 520 of the curtain wall roof unit 300. The ventilation openings of the ventilation louvers 320 face the buffer air duct 410 of the photovoltaic roof unit 400.

[0037] Upon reaching the roof unit, the rising hot airflow is blocked by the enclosed roof frame 532 and forced to deflect through the side ventilation louvers 320, smoothly entering the roof's buffer duct 410. This achieves a smooth transition of airflow from vertical to horizontal.

[0038] This embodiment describes the thermal insulation and waterproofing structure of the enclosed ceiling frame 532. The enclosed ceiling frame 532 is built on top of the metal frame structure 540, and consists of, from bottom to top, a protective layer (such as galvanized iron sheet), a thermal insulation layer (such as rock wool board), and a waterproofing layer (such as waterproof membrane or steel plate). A decorative ceiling frame is suspended below the frame structure 540.

[0039] The multi-layered structure blocks the transfer of solar radiation heat from the top to the interior of the curtain wall roof unit 300, while also preventing rainwater penetration. This ensures that the roof unit has excellent thermal insulation and waterproof performance, guaranteeing the weather resistance of the prefabricated house system.

[0040] like Figures 4A-4B As shown, Figure 4A For the overall picture, Figure 4B An internal schematic diagram of the photovoltaic panel and top frame structure is shown below. This embodiment describes the construction of the photovoltaic roof unit 400. Its base frame is an open base frame 513, directly fixed to the top of the prefabricated house unit 100, and supported to a certain height by columns 520. The photovoltaic panels 430 are directly fixed to the top frame, replacing the traditional roof panels. The regulating valve 420 is installed in the end groove formed by the column 520 and the top frame, located on the side away from the curtain wall top cover unit 300.

[0041] The photovoltaic panel 430 generates a significant amount of heat while generating electricity. The underlying buffer duct 410 allows airflow, which carries away the heat from the back of the photovoltaic panel. This BIPV (Building Integrated Photovoltaics) design not only provides electricity to the building but also reduces the operating temperature of the photovoltaic modules through rear ventilation, thereby improving photovoltaic power generation efficiency.

[0042] This embodiment specifically describes the structure of the regulating valve 420. The regulating valve 420 is a split-leaf multi-blade regulating valve, including a rectangular valve body, multiple parallel-arranged blades, and a drive shaft passing through the blades. The blades are rotatably mounted in the valve body via the drive shaft. By rotating the drive shaft, the angle of all blades can be changed simultaneously, thereby switching between open (ventilation mode) and closed (insulation mode) states.

[0043] The user or automatic control system adjusts the ventilation cross-sectional area by rotating the drive shaft. This provides precise control over the ventilation volume, enabling the system to adapt to different seasons and weather conditions.

[0044] like Figures 5A-5F As shown, Figure 5A It is an open-frame structure. Figure 5B For enclosed base frame, Figure 5C and Figure 5D For ventilation base frame, Figure 5E It is an open top frame. Figure 5F This is a closed base frame. This embodiment describes in detail the common frame structure 540 for each unit. The frame structure 540 includes four main beams 541, multiple crossbeams 542, and four end pieces 543. The four main beams 541 are connected end-to-end to form a rectangular outer frame. The multiple crossbeams 542 are arranged parallel between the opposing main beams to enhance planar stiffness. The end pieces 543 are welded to the connecting corners of adjacent main beams, serving as the main load-bearing nodes.

[0045] This forms a stable planar grid structure capable of withstanding its own weight, wind loads, and snow loads. The structure is simple, the stress distribution is reasonable, and it is easy to standardize production.

[0046] This embodiment further defines the profile specifications. The main beam 541 uses high-strength bent plate, and the crossbeam 542 uses standard C-shaped steel to reduce weight. The end 543 is prefabricated with lifting holes (for crane operations), connection holes (for bolt connections between modules), and rainwater holes (for drainage). The column 520 also uses bent plate with holes at both ends.

[0047] The combination of bent plates and C-shaped steel achieves a balance between lightweight and high strength. Prefabricated holes enable dry construction. This not only reduces material costs but also eliminates the need for on-site cutting and drilling, improving corrosion resistance and construction precision.

[0048] Metal protective mesh or grilles are installed at the ventilation openings 551 of the ventilation base 512 of the second curtain wall 220. Physical barriers are installed at the air inlets of the vertical duct 230 to prevent birds, insects, or large floating debris from entering the duct, thus avoiding duct blockage or equipment damage, while ensuring smooth ventilation.

[0049] This embodiment represents an intelligent upgrade of the aforementioned system. The system also includes an intelligent environmental control module, which comprises indoor and outdoor temperature sensors, an electric actuator connected to the drive shaft of the regulating valve 420, and a central controller.

[0050] The controller monitors the indoor and outdoor temperature difference and the temperature inside the buffer duct 410 in real time. When the temperature inside the buffer duct is higher than the outdoor temperature and also higher than the indoor temperature in summer, the controller instructs the electric actuator to fully open the regulating valve 420, utilizing the maximum thermal pressure difference for heat dissipation. When insulation is needed in winter or at night, the controller instructs the regulating valve 420 to close, using the enclosed air layer as insulation. This achieves 24 / 7 automated thermal environment management, and compared to manual operation, it can more accurately capture favorable natural ventilation opportunities, further improving energy efficiency.

[0051] This embodiment relates to improved safety performance. The input terminal of the aforementioned intelligent controller is connected to the smoke alarm or fire control center signal within the prefabricated building.

[0052] When a fire occurs inside prefabricated unit 100 and triggers the smoke alarm, regardless of the current temperature control mode, the controller forcibly drives the regulating valve 420 to switch to the fully open state. Existing ventilation ducts are used as emergency smoke exhaust shafts. Utilizing the immense thermal pressure of the high-temperature smoke generated by the fire, the smoke is rapidly expelled outdoors, buying valuable time for evacuation and significantly improving the safety of the temporary prefabricated housing.

[0053] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: Through standardized modular assembly, a complete integrated air circulation system encompassing vertical, horizontal, and buffer zones is constructed on the exterior of the temporary prefabricated houses. Utilizing the thermal pressure difference generated by solar radiation, it drives natural airflow, carrying away heat from the building envelope and cooling the photovoltaic modules. This significantly reduces the summer air conditioning load and improves photovoltaic power generation efficiency. The fully modular, bolted-connection design adapts to the rapid construction and dismantling needs of temporary building projects. Integrating multiple functions such as sun shading, ventilation, power generation, insulation, and fire smoke extraction, it greatly enhances the living quality and safety level of the temporary prefabricated houses.

[0054] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0055] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
