Description

Technical Field

[0001] This utility model relates to the field of architectural design technology, and more specifically, to an energy-saving ventilation structure for architectural design. Background Technology

[0002] Energy-saving ventilation structures in building design can be achieved through both natural ventilation and mechanical ventilation. To achieve efficient heat dissipation and air circulation on the roof, natural ventilation technologies such as ventilated roof structures, streamlined roof skylights, and ridge ventilators are typically used, supplemented by intelligent ventilation devices or low-energy mechanical fans. Through a composite design of natural power, intelligent control, and mechanical assistance, the efficient exhaust of hot air from the roof and the circulation of internal and external air are achieved, thereby reducing building energy consumption.

[0003] In the field of natural ventilation in buildings, traditional ventilation designs often rely on skylights or exhaust vents for rooftop ventilation. Since the exhaust efficiency of skylights or exhaust vents is highly dependent on the synergistic effect of thermal pressure and wind pressure, when the surrounding buildings block the wind pressure and cause insufficient wind pressure, it is difficult to form a continuous airflow by thermal pressure alone. Especially in flat or enclosed roof structures, hot air tends to accumulate at the top and cannot be effectively exhausted. Furthermore, traditional designs lack a through-ventilation channel with the lower floors, and after the skylight exhausts air, the cold air at the lower floors cannot be replenished in time, resulting in stagnant air circulation on the rooftop.

[0004] Therefore, we propose an energy-saving ventilation structure for building design. Utility Model Content

[0005] This utility model provides an energy-saving ventilation structure for building design. It features a hollow roof with a grid-like steel frame at the top of the building. Z-shaped air inlet ducts, straight ducts, and outlet ducts are installed between the ground, basement, and the building and roof, respectively. This allows air to flow from the ground through the basement, building, and roof, forming a continuous ventilation path. The hollow grid-like steel frame structure further optimizes airflow on the roof by integrating its internal space into the air circulation path. Utilizing natural forces such as thermal pressure and wind pressure, along with the rational layout of the ducts, continuous air circulation and efficient exchange are achieved, thus solving the problems mentioned in the background art.

[0006] Traditional rooftop ventilation designs rely on skylights or exhaust vents, which are easily affected by wind pressure. They also lack a continuous ventilation channel, making it difficult to effectively remove hot air from the rooftop and causing air circulation to stagnate.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An energy-saving ventilation structure for building design includes a ground floor, a building on top of the ground floor, a basement at the bottom of the building, and the basement located inside the ground floor; a roof on top of the building, the roof having a hollow structure inside, and a steel frame inside the roof.

[0009] An air intake duct is provided between the ground floor and the basement, a straight-through duct is provided between the basement and the building and the roof, and an air outlet duct is provided inside the roof.

[0010] Preferably, the steel frame is grid-shaped, the interior of the steel frame is hollow, the steel frame is located inside the roof near the center, and gaps are left between the steel frame and the top and bottom of the roof inner wall.

[0011] Preferably, the steel frame has an internal ramp, and multiple ends of the steel frame are provided with windows, the ramp being used to guide seepage water inside the steel frame.

[0012] Preferably, the air intake duct has a Z-shaped structure, with one end of the air intake duct located above the ground and the other end located inside the basement, and both ends of the air intake duct are equipped with electrical grids.

[0013] Preferably, one end of the straight pipe is located inside the roof and the other end is located inside the basement, and the end of the straight pipe located in the basement is equipped with an electric grid.

[0014] Preferably, one end of the air outlet duct is located inside the roof and the other end is located above the roof, and the end of the air outlet duct located above the roof is equipped with an electric grid.

[0015] Preferably, the power grid is located at the inner end of the air inlet duct, the straight-through duct, and the air outlet duct.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In an energy-saving ventilation structure for building design, a hollow roof with a grid-like steel frame is set on the top of the building. Air inlet ducts, straight ducts, and outlet ducts are set on the ground, basement, and between the building and the roof. Natural forces such as thermal pressure and wind pressure are used to promote the continuous and stable circulation of air through the coordinated cooperation between the components. This overcomes the problems of traditional roof ventilation relying on skylights or exhaust vents being easily affected by wind pressure and air circulation easily stagnating. It improves ventilation efficiency and allows the internal space of the steel frame to be integrated into the air circulation path, forming a through ventilation channel and improving the ventilation and cooling effect of the roof.

[0018] 2. In an energy-saving ventilation structure for building design, the ground windows, in conjunction with the hollow structure inside the steel frame, play a positive role in ventilation. This allows outside air to enter the hollow structure through the ground windows and integrate into the ventilation path of the entire building, facilitating air circulation and exchange. Moreover, the ground windows also serve to block mosquitoes. Their structural design is similar to that of ancient ground windows, combining practicality with aesthetics. When water seepage occurs in the roof, the slope is used to guide the seepage water, allowing it to flow down the slope to the ground windows for discharge, preventing water accumulation inside the roof, protecting the roof structure, and ensuring the normal operation of the ventilation structure. This achieves a synergistic effect between waterproofing, drainage, and ventilation functions.

[0019] 3. In an energy-saving ventilation structure for building design, an electric grid is installed at the inner end of the air inlet duct, straight duct, and outlet duct. This inner placement of the grid prevents accidental injury to people or pets in the surrounding area, ensuring safety while effectively blocking birds, leaves, and other foreign objects from entering the ducts. This prevents the accumulation of foreign objects that could clog the ducts, thus avoiding impaired ventilation. It also eliminates potential safety hazards caused by foreign objects entering the ducts, such as affecting the normal operation of equipment. This ensures that each duct can function continuously and stably within the entire ventilation structure, maintaining smooth airflow and achieving a synergy between safety protection and ventilation function.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Current traditional rooftop ventilation designs, relying on skylights or exhaust vents, are susceptible to wind pressure fluctuations and lack a continuous ventilation channel, leading to technical challenges such as ineffective removal of hot air and stagnant air circulation. Please refer to [link to relevant documentation]. Figures 1-3 The building design energy-saving ventilation structure shown includes a ground 2, a building 1 on top of the ground 2, a basement 11 at the bottom of the building 1, the basement 11 being located inside the ground 2; a roof 12 on top of the building 1, the roof 12 having a hollow structure inside, and a steel frame 13 inside the roof 12.

[0029] An air intake duct 15 is provided between ground 2 and basement 11, a straight-through duct 16 is provided between basement 11, building 1 and roof 12, and an air outlet duct 17 is provided inside roof 12.

[0030] Outside air can be introduced into basement 11 through air intake duct 15 between ground floor 2 and basement 11. Straight duct 16 between basement 11 and building 1 and roof 12 connects the various parts, allowing air to be transported from basement 11 to roof 12. Air exhaust duct 17 inside roof 12 is responsible for exhausting hot air to the outside. When there are natural forces such as thermal pressure and wind pressure in the outside, air first enters basement 11 through air intake duct 15, then passes through each floor of building 1 and reaches roof 12 through straight duct 16, and finally is exhausted through air exhaust duct 17. The ducts and the internal structure of roof 12 work together to build a through ventilation channel, so that hot air on the top floor can be effectively exhausted. At the same time, when there is wind in the outside passing through roof 12, the space formed by the steel frame 13 in the hollow structure further optimizes the air circulation path of the top floor and improves the ventilation effect of the top floor.

[0031] For details, see Figure 4 and Figure 5 As shown, the steel frame 13 is grid-like and has a hollow interior. Located near the center of the roof 12, the steel frame 13 has gaps at its top and bottom relative to the inner wall of the roof 12. The steel frame 13 has an internal ramp 130, and multiple ends are equipped with floor windows 14. The ramp 130 is used to guide any seepage water within the steel frame 13.

[0032] When rainwater seeps into the internal steel frame 13 structure of the roof 12 during rainy weather, the rainwater will flow along the slope 130 because the steel frame 13 is grid-like and has an internal slope 130. The ground windows 14 set at multiple ends of the steel frame 13 become drainage channels for the seepage. Under the action of gravity, the rainwater that seeps into the steel frame 13 gradually gathers along the slope 130 and flows to the ground windows 14, and is finally discharged to the outside through the ground windows 14. This prevents rainwater from accumulating inside the steel frame 13, prevents damage to the roof 12 structure due to water accumulation, and ensures the normal operation of the roof 12 and the entire ventilation structure.

[0033] Meanwhile, the ground window 14 not only serves a drainage function, but also plays a role in ventilation when combined with the hollow structure inside the steel frame 13. Outside air can enter the hollow structure through the ground window 14, thereby helping the air circulation and exchange on the top floor. In addition, the ground window 14 can also block mosquitoes from entering by its own structure. While achieving waterproofing, drainage and ventilation functions, it is also aesthetically pleasing and practical.

[0034] Additionally, see Figure 3 and Figure 6 As shown, the air intake duct 15 has a Z-shaped structure, with one end located above ground level 2 and the other end located inside basement 11. Both ends of the air intake duct 15 are equipped with electrical grids 18. One end of the straight-through duct 16 is located inside roof 12 and the other end is located inside basement 11. The end of the straight-through duct 16 located in basement 11 is equipped with an electrical grid 18. One end of the air outlet duct 17 is located inside roof 12 and the other end is located above roof 12. The end of the air outlet duct 17 located above roof 12 is equipped with an electrical grid 18.

[0035] It should be noted that, in order to ensure the efficiency of thermal pressure ventilation and to avoid excessive airflow resistance due to excessive length of the straight pipe 16, the height of the building 1 should be controlled within 30 meters (approximately 10 stories or less) to ensure that the air can rise stably to the roof 12 with low resistance in the straight pipe 16.

[0036] Because the steel frame 13 inside the roof 12 has a grid-like structure and a hollow interior, and is located near the center of the roof 12, with gaps at the top and bottom of the roof 12's inner wall, when the ventilation system is running, air flows between the straight duct 16 and the outlet duct 17, circulating in the remaining space inside the roof 12 excluding the space occupied by the steel frame 13. The hollow design of the steel frame 13 itself creates an independent airflow channel within it. The airflow in these two parts proceeds independently, without interference or flow between them, effectively constructing two relatively independent yet coordinated ventilation structures. This optimizes the airflow path in the roof 12 area and improves the overall ventilation efficiency.

[0037] The air intake duct 15 adopts a Z-shaped structure, with one end above the ground 2 for better contact with outside air, and the other end extending into the basement 11. This special shape is conducive to introducing outside air more rationally according to factors such as terrain and wind direction. At the same time, the electric grid 18 set at both ends can block foreign objects such as birds and leaves from entering the duct when air enters, preventing foreign objects from accumulating in the duct with the air flow and ensuring smooth air intake.

[0038] The straight pipe 16 connects the basement 11 and the roof 12, with one end in the basement 11 and the other end inside the roof 12. The electric grid 18 located at the basement 11 end also plays the role of intercepting foreign objects, preventing debris that may exist around the basement 11 from entering the pipe, ensuring that air can be stably transmitted from the basement 11 to the roof 12, and maintaining the continuity of air circulation throughout the building.

[0039] One end of the exhaust duct 17 is inside the roof 12, and the other end is located above the roof 12. The electric grid 18 installed at the end above the roof 12 prevents foreign objects from entering the duct in reverse, thus avoiding affecting the exhaust of hot air and ensuring that hot air from the roof can be smoothly exhausted to the outside through the exhaust duct 17. Through their unique structures and the electric grid 18, each duct, together with the steel frame 13 structure inside the roof 12, ensures the stable and efficient operation of the entire building's ventilation structure, achieving good ventilation and air exchange effects and solving the problems existing in traditional roof ventilation.

[0040] Among them, the electrical grid 18 is located at the inner end of the air inlet duct 15, the straight-through duct 16, and the air outlet duct 17. On the one hand, it can effectively prevent foreign objects such as birds, leaves, and debris from entering the duct, preventing them from accumulating and blocking the duct with the airflow, ensuring smooth airflow in each duct, and maintaining the stable operation of the entire ventilation structure. On the other hand, the inner position can prevent the electrical grid 18 from being too close to the external environment of the building, thereby reducing the possibility of accidental injury to people, pets, etc. in the surrounding area, ensuring the normal functioning of ventilation while taking into account the safety of use.
