[0040] refer to Figures 1 to 6This utility model provides a window-type ventilation system 100, including a window structure 1, an air supply module 2, and an exhaust module 3. The air supply module 2 is located below the window structure 1; it includes a first outer shell 4; the surface of the first outer shell 4 is coated with a heat-insulating coating; the first outer shell 4 has a first ventilation duct 5, one end of which has a first air inlet 6, and the other end of which has a first air outlet 7, located at the left and right ends of the window structure 1; the inner wall of the first ventilation duct 5 is provided with a sound-absorbing material layer; the first air inlet 6 has a first filter structure 8, and the first air outlet 7 has a second filter structure 9, which are used to filter particulate matter and reduce noise; the exhaust module 3... The ventilation module 3 and exhaust module 3 are located above the window structure 1. The air supply module 2 includes a second housing 10. The second housing 10 has a second ventilation duct 11. One end of the second ventilation duct 11 has a second air inlet 12, and the other end has a second air outlet 13.

The second air inlet 12 is provided with a third filter structure 14, and the second air outlet 13 is provided with a fourth filter structure 15. The third filter structure 14 and the fourth filter structure 15 are used to filter particulate matter and reduce noise. In this embodiment, the window structure 1 is mounted on a wall. One side of the window structure 1 is indoors, and the other side is outdoors. The first air inlet 6 faces and connects to the outdoors, and the first air outlet 7 faces and connects to the indoors. The second air inlet 12 faces and connects to the indoors, and the second air outlet 13 faces and connects to the outdoors.
[0041] This system incorporates a first filter structure 8, a second filter structure 9, a third filter structure 14, and a fourth filter structure 15 in the air supply module 2 and the exhaust module 3, respectively, to reduce the transmission of particulate matter and noise. A sound-absorbing material layer further reduces noise transmission. A heat-insulating coating is applied to the exterior of the first outer shell 4. This coating can be a metal oxide coating, such as zinc oxide, or an organic heat-insulating coating, such as a polyester film coating. This reduces external heat transfer, helps control external heat transfer, and further enhances the thermal pressure ventilation effect, causing outdoor air to enter the room through the air supply module and indoor air to exit through the exhaust module, thus improving the system's energy efficiency. This system offers advantages in high-efficiency sound insulation, air purification, and heat control, making it suitable for noise-sensitive areas and urban environments with heavy air pollution.
[0042] refer to Figure 2The first ventilation duct 5 has opposing first side 16 and second side 17. A first air inlet 6 is located on the first side 16, and a first air outlet 7 is located on the second side. In this embodiment, the first outer shell 4 is made of aluminum alloy. The first outer shell 4 is rectangular, and a rectangular cavity within it forms the first ventilation duct 5. The first side 16 and second side 17 of the first ventilation duct 5 are parallel. At least one baffle 20 is provided inside the first ventilation duct 5. The baffle 20 is used to create a curved path within the first ventilation duct 5. The width of the baffle 20 is smaller than the width of the rectangular cavity. Multiple baffles 20 are staggered and perpendicularly arranged on the first side 16 and second side 17. Air enters the first ventilation duct 5 through the first air inlet 6, passes through the curved path formed by the multiple baffles, and exits from the first air outlet 7. The baffles 20 obstruct noise and extend the airflow channel, thereby increasing the area of the sound-absorbing material, improving the sound absorption effect, and better reducing noise.
[0043] like Figure 3 The second ventilation duct 11 has opposing third side 18 and fourth side 19. A second air inlet 12 is located on the third side 18, and a second air outlet 13 is located on the fourth side 19. In this embodiment, the second outer shell 10 is made of aluminum alloy. The second outer shell 10 is cuboid in shape, and a cuboid cavity within it forms the second ventilation duct 11. The third side 18 and fourth side 19 of the second ventilation duct 11 are parallel. At least one baffle 20 is provided within the second ventilation duct 11. The baffle 20 is used to create a bent path inside the second ventilation duct 11. The width of the baffle 20 is smaller than the width of the cuboid cavity. Multiple baffles 20 are staggered and perpendicularly arranged on the third side 18 and fourth side 19. Air enters the second ventilation duct 11 through the second air inlet 12, passes through the bent path formed by the multiple baffles 20, and is discharged from the second air outlet 13. The baffle 20 obstructs noise and extends the airflow channel to increase the area of sound-absorbing material, improve the sound absorption effect, and better reduce noise.
[0044] In this embodiment, the second air outlet 13 and the first air inlet 6 are staggered and positioned at the top and bottom ends of the window structure 1, facing outwards. Figure 1 The second air inlet 12 and the first air outlet 7 are staggered and placed at the top and bottom of the window structure 1 and face the room.
[0045] refer to Figure 2 and Figure 3One end of the first air inlet 6 is provided with a first end plate 21 perpendicular to the first side 16, and the first end plate 21 and one end of the first ventilation duct 5 form a first groove 22; one end of the first air outlet 7 is provided with a second end plate 23 perpendicular to the second side 17, and the second end plate 23 and the other end of the first ventilation duct 5 form a second groove 24; one end of the second air inlet 12 is provided with a third end plate 25 perpendicular to the third side 18, and the first end plate 21 and one end of the second ventilation duct 11 form a third groove 26; one end of the second air outlet 13 is provided with a fourth end plate 27 perpendicular to the fourth side 19, and the second end plate 23 and the other end of the second ventilation duct 11 form a fourth groove 28.
[0046] Specifically, the first filter structure 8 includes a first stainless steel wire mesh 29 and a first composite filter 30; the second filter structure 9 includes a second stainless steel wire mesh 31 and a first filter 32; the first stainless steel wire mesh 29 is disposed at one end of the first groove 22 away from the second side 17, and the first composite filter 30 is disposed at the other end of the first groove 22 facing the second side 17; the second stainless steel wire mesh 31 is disposed at one end of the second groove 24 away from the first side 16, and the first filter 32 is disposed at the other end of the second groove 24 facing the first side 16.
[0047] In this embodiment, the end of the first end plate 21 away from the first side 16 and the end of the second end plate 23 away from the second side 17 are respectively provided with protrusions 37. A first stainless steel wire mesh 29 is snapped into one end of the first groove 22, and a first composite filter 30 is disposed between the first stainless steel wire mesh 29 and the protrusions 37. A second stainless steel wire mesh 31 is snapped into one end of the second groove 24, and a first filter 32 is disposed between the second stainless steel wire mesh 31 and the protrusions 37. In this embodiment, the first filter 32 is used for secondary filtration to ensure clean indoor air.
[0048] Specifically, the third filter structure 14 includes a third stainless steel wire mesh 33 and a second filter 34; the fourth filter structure 15 includes a fourth stainless steel wire mesh 35 and a second composite filter 36. The third stainless steel wire mesh 33 is disposed at one end of the third groove 26, and the second filter 34 is disposed at the other end of the third groove 26 facing the fourth side 19. The fourth stainless steel wire mesh 35 is disposed at one end of the fourth groove 28, and the second composite filter 36 is disposed at the other end of the fourth groove 28 facing the third side 18. In this embodiment, the ends of the third end plate 25 and the fourth end plate 27 away from the third side 18 and the fourth side 19 are respectively provided with protrusions 37. The third stainless steel wire mesh 33 is snapped into one end of the third groove 26, and the second filter 34 is disposed between the third stainless steel wire mesh and the protrusion 37. The fourth stainless steel wire mesh 35 is snapped into one end of the fourth groove 28, and the second composite filter 36 is disposed between the fourth stainless steel wire mesh 35 and the protrusion 37.
[0049] Specifically, the first stainless steel wire mesh 29 and the second stainless steel wire mesh 31 are used to intercept larger particles. The principle for selecting the aperture of the first stainless steel wire mesh 29 and the second stainless steel wire mesh 31 is to be able to intercept larger particles without causing excessive air resistance. In this embodiment, the preferred aperture range of the stainless steel wire mesh is approximately 200 to 400 mesh, where mesh number refers to the number of openings per inch. In another embodiment, the selection of the optimal aperture and mesh number needs to be optimized through experiments or simulations based on the airflow rate of the specific system, the expected size of the particles to be filtered, and the overall energy consumption requirements of the system. For example, for applications requiring a large airflow but with a low particle load, a mesh with a larger aperture can be selected; conversely, a mesh with a smaller aperture can be selected to improve filtration efficiency.
[0050] In this embodiment, the first composite filter 30 and the second composite filter 36 are the same composite filter. The first composite filter 30 includes two layers of wire mesh, with a foam layer, a HEPA material layer, and a filter cotton layer arranged sequentially between the two wire mesh layers. During installation, the side with the foam layer is placed close to the first stainless steel wire mesh 29. In this embodiment, the wire mesh is galvanized steel wire mesh; the foam layer is open-cell polyurethane foam 40; the HEPA material layer is HEPA filter material 40, including glass fiber type, polypropylene nonwoven type, synthetic fiber blend type, electrostatic reinforced material, etc.; the filter cotton layer is polyester fiber filter cotton 39. The composite filter consists of galvanized steel wire mesh, polyester fiber filter cotton 39, HEPA filter material 40, and open-cell polyurethane foam 40, which absorbs and reduces mid-to-high frequency noise while ensuring ventilation. The galvanized steel wire mesh initially filters larger particles. The polyester fiber filter cotton 39 further filters finer particles. The HEPA filter material 40 efficiently filters microparticles, such as PM2.5. The open-cell polyurethane foam 40 utilizes its sound-absorbing properties to absorb mid-to-high frequency noise. Both the first and second composite filters are composed of galvanized steel wire mesh, polyester fiber filter cotton, HEPA filter material, and open-cell polyurethane foam, respectively. Their main function is to absorb and reduce mid-to-high frequency noise while ensuring ventilation, and to perform preliminary filtration of larger and medium-sized particles.
[0051] Specifically, the first filter 32 and the second filter 34 are both HEPA high-efficiency filters. HEPA high-efficiency filters are high-efficiency particulate air filters used to efficiently remove fine particulate matter such as PM2.5. HEPA high-efficiency filters must be able to capture at least 99.97% of particles with a diameter of 0.3 micrometers. When designing or selecting HEPA high-efficiency filters, it is necessary to balance filtration efficiency with airflow resistance and select appropriate HEPA filter materials to ensure the overall energy efficiency and economy of the system.
[0052] Specifically, in the air supply module, a first composite filter is used as the inlet filtration unit to perform primary filtration and noise reduction on the incoming air, followed by fine filtration through the first filter at the outlet to ensure clean air entering the room. In the exhaust module, a second filter is installed at the inlet to prevent fine particles from the indoor air from directly escaping; a second composite filter is used at the outlet to absorb potential noise in the exhaust airflow. This combination design allows air purification and noise control to work together, ensuring air quality while suppressing indoor and outdoor noise. Using only a single filter or swapping the positions of the two filters would result in insufficient primary filtration or noise reduction, thus affecting the overall system performance.
[0053] Specifically, the sound-absorbing material layer includes a polyester fiber cotton board 42 and a thin-film acoustic metamaterial 43. The polyester fiber cotton board 42 is installed on the inner wall of the first ventilation duct 5 and the second ventilation duct 11; the thin-film acoustic metamaterial 43 is installed on the outside of the baffle 20, as shown in the reference. Figure 5 The thin-film acoustic metamaterial 43 is a silicone film structure, which includes a circular silicone mass block 44 and a silicone film 45. It absorbs low-frequency noise, and the low-frequency sound absorption can be increased by arranging the acoustic metamaterials of different masses 44 at unequal intervals. In another embodiment, the sound-absorbing material layer includes a polyester fiber cotton board and a mineral wool sound-absorbing board. The mineral wool sound-absorbing board is installed on the inner wall of the first ventilation duct 5 and the second ventilation duct 11, and the polyester fiber cotton board is installed on the outside of the baffle 20.
[0054] Specifically, the air supply module 2 also includes a first fan 46, which is located within the first ventilation duct 5 near the first air inlet 6. In this embodiment, the air outlet direction of the first fan 46 is parallel to the first side 16, and the air blown by the first fan 46 blows from one end of the first ventilation duct 5 to the other. The first fan 46 is a DC brushless fan, which reduces operating noise and provides aerodynamics to ensure effective entry of fresh air into the room. Specifically, the exhaust module 3 also includes a second fan 47, which is located within the second ventilation duct 11 near the second air outlet 13. In this embodiment, the air outlet of the second fan 47 faces outward from the second air outlet 13. The first fan 46 can be a DC brushless fan, and the second fan 47 provides aerodynamics to ensure effective exhaust of air outdoors. Through the arrangement of the first fan 46 and the second fan 47, it can be further ensured that outdoor air enters the room from the air supply module 2, and indoor air is transferred to the outside from the exhaust module 3.
[0055] Specifically, the window structure 1 includes a window frame 48 and a multi-layered glass structure 49, with the multi-layered glass structure 49 housed within the window frame 48. The window frame 48 can be made of aluminum alloy, and the multi-layered glass structure 49 is housed within the aluminum alloy window frame 48 to form the window structure 1. (Reference) Figure 6 The multi-layer glass structure 49 is composed of glass 50, air layer 51, and PVB laminated glass 52. The edges of the multi-layer glass structure 49 are sealed with silicone sealing strips to ensure the overall sound insulation performance and airtightness of the system. In this embodiment, a 5mm glass 50, a 12mm air layer 51, and PVB laminated glass 52 are used to form the multi-layer glass structure 49. PVB laminated glass 52 is a composite glass material in which polyvinyl butyral (PVB) film is sandwiched between two or more layers of glass, such as 6mm glass 50, 0.76mm PVB laminate 53, and 6mm glass 50. The combination of glass 50, air layer 51, and PVB laminated glass 52 enhances the sound insulation performance. The silicone sealing strips ensure the seal between the glass 50s, prevent air leakage, and enhance airtightness and sound insulation.
[0056] Specific working principle:
[0057] This system utilizes the principle of thermo-pressure ventilation, through the cooperation of air supply module 2 and exhaust module 3, to achieve indoor and outdoor air exchange. In this system, thermo-pressure ventilation refers to using the pressure difference created by the temperature difference between indoors and outdoors to promote natural airflow. When the indoor temperature is higher than the outdoor temperature, the hot indoor air rises. Since the air supply module is installed below the window structure 1 and the exhaust module 3 is installed above it, this arrangement naturally creates air convection, ensuring that hot air flows upwards. This creates negative pressure in the upper part, i.e., the exhaust module 3, allowing fresh outdoor air to enter the room through the lower air supply module 2. The thermo-pressure ventilation principle effectively improves ventilation efficiency and reduces energy consumption. Simultaneously, the aluminum alloy shell of the air supply module 2 is coated with a heat-insulating coating, which helps control the transfer of external heat and further enhances the thermo-pressure ventilation effect. The exhaust module 3 does not have a heat-insulating coating on its outer shell. Its structural design works in conjunction with the second fan 47 and the bend-shaped second ventilation duct 11, and the supply air module 2 works in conjunction with the first fan 46 and the bend-shaped first ventilation duct 5, thereby ensuring that air flows along a predetermined path and preventing the supply air module 2 and exhaust module 3 from directly connecting to the indoor and outdoor environments and causing a short-circuit effect. The effective air exchange is further ensured by setting up the first fan 46 and the second fan 47.
[0058] External air passes through the first stainless steel wire mesh 29 and the first composite filter 30 located at the first air inlet 6 in the air supply module 2, and enters the first ventilation duct 5, which has a baffle forming a bent path and is covered with a layer of sound-absorbing material. This removes particulate matter and pollutants, reducing noise transmission. The air then passes through the first filter 32 and the second stainless steel wire mesh 31 before entering the room from the first air outlet 7. Indoor air passes through the second stainless steel wire mesh 31 and the second filter 34 located at the second air inlet 12 in the exhaust module 3, and enters the second ventilation duct 11, which has a baffle forming a bent path and is covered with a layer of sound-absorbing material. This removes particulate matter and pollutants, reducing noise transmission. The air then passes through the second composite filter 36 and the fourth stainless steel wire mesh 35 before exiting to the outside from the second air outlet 13. Indoor air is exhausted through exhaust module 3, which also has sound absorption and filtration functions. On the one hand, it prevents external noise and pollutants from entering the room through exhaust module 3 to a certain extent; on the other hand, it prevents noise and pollutants from leaking out when the filtered indoor air is exhausted. The design takes into account both preventing indoor noise from spreading outward and suppressing the backflow of external noise. The multi-layer glass structure 49 of the window structure 1 enhances the sound insulation and heat preservation performance of the system, realizing the functions of air purification, noise control, and heat management, providing a quiet, clean, and comfortable indoor environment. This system combines a composite filter and a thin-film acoustic metamaterial 43 to meet the needs of high-efficiency air filtration and full-frequency noise absorption, making it particularly suitable for noise-sensitive urban environments. The tortuous path design of the first ventilation duct 5 and the second ventilation duct 11 increases the area of sound-absorbing material and improves sound absorption performance. The heat insulation coating of the first shell 4 and the sealing design of the window structure 1 enhance the heat control and heat insulation effect of the system based on the thermal pressure ventilation principle.
