Description

Technical Field

[0001] This invention relates to the field of ventilation equipment technology, specifically a ventilation system for green buildings. Background Technology

[0002] Green buildings refer to buildings that provide people with habitable, living, and productive spaces while conserving resources, protecting the environment, and reducing pollution. As people's living standards improve, the health, suitability, and efficiency of buildings are also receiving more attention. People hope to enjoy a comfortable life while minimizing their environmental impact.

[0003] Substations have strict requirements for temperature, humidity, and air cleanliness in their control rooms, relay protection rooms, communication equipment rooms, and other auxiliary buildings. The precision electronic equipment in these rooms needs to operate in a constant temperature and humidity environment; environmental fluctuations can lead to equipment malfunctions, performance degradation, or even damage. Traditional air conditioning systems are extremely energy-intensive, while simple ventilation systems cannot address the problems under extreme weather conditions: directly introducing hot air in summer increases the cooling load, while introducing cold air in winter can cause localized condensation on equipment. Furthermore, substations are typically located in suburban areas or outdoors, where dry winter air can easily generate static electricity, threatening the safety of electronic equipment. Therefore, a ventilation solution that provides stable, energy-efficient, and intelligently regulated humidity for substation auxiliary buildings is needed.

[0004] Existing ventilation systems need to maintain a constant temperature when introducing outdoor air to avoid excessive temperature differences between indoors and outdoors, which can cause discomfort. Conventional solutions use heat exchangers to exchange heat between exhaust air and fresh air, but this method has inherent drawbacks: with continuous ventilation, the indoor temperature will gradually approach that of the outdoor environment, eventually disrupting the thermal equilibrium and affecting human comfort.

[0005] Therefore, the present invention provides a ventilation system for green buildings to solve the problems mentioned above. Summary of the Invention

The combination of vortex tubes and the second heat exchange component deeply cools or heats fresh air without relying on refrigerant, ensuring suitable air temperature in critical areas such as the control room. In particular, the integrated humidification component actively humidifies the air under dry winter conditions, preventing static electricity and providing a safe and stable operating environment for the precision electronic equipment within the substation.

[0018] 2. This system ventilates the building, enabling heat exchange between indoor and outdoor gases, reducing the temperature difference between the two. When used for indoor living environment regulation, it can maintain thermal balance and prevent large temperature differences from causing sudden temperature changes that could affect the comfort of indoor occupants.

[0019] 3. This system ventilates the building. During operation, gas passes through the first piston plate and the second through-pipe into the adjacent inner pipe for circulation. The gas is gradually compressed, and the compressed gas enters the vortex tube through the nozzle. The compressed gas accelerates and expands inside the vortex tube, forming a high-speed rotating vortex field, which is divided into hot and cold airflows, which are discharged through the hot and cold airflow outlets respectively. The compression component and docking component heat the gas in the inner pipe, increasing the gas volume, improving the gas compression efficiency, and enhancing the cooling and heating effect of the vortex tube. The humidification component and docking component can increase the humidity of the air entering the room in winter, preventing excessive dryness from affecting the comfort of indoor occupants.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 and Figure 2 The green building ventilation system shown in this embodiment includes a ventilation box 100. The ventilation box 100 is configured as a box structure composed of six cover plate assemblies, which are connected and assembled by pins. The internal cavity of the box structure is a hollow rectangle. Ventilation components for air exchange inside the building are installed at both ends of the ventilation box 100. The ventilation components include a first air pipe 110, a second air pipe 111, a third air pipe 112, and a fourth air pipe 113. The first air pipe 110 and the second air pipe 111 are located outdoors, while the third air pipe 112 and the fourth air pipe 113 are located indoors. The ventilation components are connected to the interior of the ventilation box 100. The ventilation box 100 has ventilation components installed at both ends of its inner wall. The ventilation box 100 is equipped with partitions 140 for dividing the internal space. A heat exchange box 200 is installed in the middle of the inner wall of the ventilation box 100. The heat exchange box 200 is installed between the partitions 140 on both sides. The heat exchange box 200 and the partitions 140 on both sides divide the internal space of the ventilation box 100 into four chambers. The four chambers are the first chamber located in the upper left, the second chamber located in the lower left, the third chamber located in the upper right, and the fourth chamber located in the lower right. The second air pipe 111, the first air pipe 110, the fourth air pipe 113, and the third air pipe 112 are respectively connected to the first chamber, the second chamber, the third chamber, and the fourth chamber. The heat exchange box 200 is equipped with a first heat exchange component for exchanging heat between the incoming and outgoing gases. The second and fourth chambers inside the ventilation box 100 are equipped with vortex fans 121 for assisting gas entry and exit. The vortex fans 121 drive external gas into the ventilation box 100 through the first air pipe 110 and the third air pipe 112. An electrical box 120 is installed on one side of the ventilation box 100. The electrical box 120 is electrically connected to the vortex fans 121. When ventilation is required, the vortex fans 121 at both ends are turned on. The vortex fans 121 draw outdoor gas into the second chamber through the first air pipe 110, and the vortex fans 121 on the other side draw indoor gas into the fourth chamber through the third air pipe 112. After the gas is heat-exchanged in the heat exchange box 200, the outdoor gas is discharged into the room through the fourth air pipe 113, and the indoor gas is discharged to the outside through the second air pipe 111 on the first chamber, thus ventilating the building.

[0035] See Figure 5A control box 300 is installed in the third chamber of the ventilation box 100. The inner wall of the control box 300 is fixedly connected with a horizontal plate 320 and a vertical plate 321 that are perpendicular to each other. The horizontal plate 320 and the vertical plate 321 divide the internal space of the control box 300 into four chambers, namely the first air intake chamber located in the upper left, the second air intake chamber located in the lower left, the heat exchange chamber located in the upper right, and the control chamber located in the lower right.

[0036] The control box 300 has air inlet pipes 311 fixedly connected to both ends on the side near the heat exchange box 200. The air inlet pipes 311 on both sides are connected to the first air inlet chamber and the second air inlet chamber respectively. The side of the air inlet pipe 311 away from the control box 300 has an air inlet port 310 fixedly connected for air intake. The heat exchange chamber has through holes at both ends for gas to pass through. Outdoor gas passes through the heat exchange box 200 and enters the third chamber. At this time, the gas can pass through the air inlet port 310 and the air inlet pipe 311 to enter the first air inlet chamber and the second air inlet chamber.

[0037] A compression assembly for compressing gas is installed on one side of the inner wall of the control box 300, located inside the control cavity. A vortex tube 500 is installed on the other side of the inner wall of the control box 300, located inside the control cavity. A mounting bracket 501 is fixedly connected to the outer wall of the vortex tube 500. The mounting bracket 501 is installed on the inner wall of the control box 300.

[0038] A second heat exchange component is installed in the heat exchange chamber located in the upper right corner inside the control box 300. A humidification component for increasing gas humidity is also installed in the heat exchange chamber of the control box 300. A docking component for connection is installed on the vortex tube 500. The docking component is connected to the second heat exchange component, the humidification component, and the extrusion component. The gas in the second air inlet chamber can be compressed by the extrusion component and then enter the vortex tube 500. The vortex tube 500 converts the compressed gas into hot air and cold air. In summer, the hot air is delivered to the extrusion component through the docking component to heat the gas at the extrusion component and improve the gas compression efficiency. The cold air flows into the second heat exchange component. The gas in the first air inlet chamber enters the heat exchange chamber, is cooled by the second heat exchange component, and then enters the room. In winter, the hot air enters the second heat exchange component to heat the gas entering the room, and the cold air enters the humidification component to liquefy the water vapor in the gas and spray it to increase the humidity of the air entering the room.

[0039] For more details, please refer to Figure 2 and Figure 4The ventilation box 100 has two through sliding grooves on its side wall. A sliding frame 131 is slidably connected to the inner wall of the sliding groove. A filter plate 132 is fixedly connected to the inner wall of the sliding frame 131. An mounting plate 130 is fixedly connected to one end of the sliding frame 131. The mounting plate 130 is installed on the side wall of the ventilation box 100 by bolts. Specifically, when filtration is required, the mounting plate 130 is pushed to move the sliding frame 131 in the sliding groove, so that the filter plate 132 can cover both sides of the heat exchange box 200. The gas in the second chamber and the fourth chamber can enter the heat exchange box 200 for heat exchange after being filtered by the filter plate 132. The impurities on the filter plate 132 can be cleaned by removing the bolts on the mounting plate 130 and sliding the sliding frame 131 out.

[0040] See Figure 7 and Figure 8 The extrusion assembly includes an outer tube 400, a compression tube 410, and a control tube 420. Multiple outer tubes 400 are provided. An inner tube 401 is installed inside each outer tube 400, and a cavity is left between the outer tubes 400 and the inner tubes 401. Control tubes 420 are installed between adjacent outer tubes 400 and are connected to the inner tubes 401. One end of the inner tube 401 is connected to the vortex tube 500. The compression tube 410 is connected to the other end of the inner tube 401 and is connected to the second air intake chamber. Gas in the second air intake chamber enters the inner tube 401 through the compression tube 410, and is compressed sequentially by multiple control tubes 420 and inner tubes 401 before entering the vortex tube 500.

[0041] See Figure 6 A nozzle 504 is installed at one end of the vortex tube 500, and a hot flow outlet 503 is installed at the other end. A cold flow outlet 502 is installed on one side of the outer wall of the vortex tube 500. The nozzle 504 is connected to the inner tube 401. When the compressed gas enters the nozzle 504 through the inner tube 401, it accelerates and expands under the action of the vortex tube 500, forming a high-speed rotating free vortex. The hot gas flow can then be discharged through the hot flow outlet 503, and the cold gas flow can be discharged through the cold flow outlet 502. The docking assembly includes a first branch pipe 510, a second branch pipe 520, and a third branch pipe 530. The third branch pipe 530 is installed on the inner wall of the horizontal plate 320. The second branch pipe 520 and the first branch pipe 510 are respectively connected to the cold flow outlet 502 and the hot flow outlet 503. A third connecting pipe 521 is installed between the second branch pipe 520 and the third branch pipe 530. A second connecting pipe 512 is installed between the first branch pipe 510 and the third branch pipe 530. A fourth connecting pipe 522 is installed at the other end of the second branch pipe 520. A first connecting pipe 511 is installed at the other end of the first branch pipe 510. The first connecting pipe 511 is connected to the inside of the outer pipe 400. The first branch pipe 510, the second branch pipe 520, and the third branch pipe 530 are connected to the inner wall of the horizontal plate 320. Both the first branch pipe 520 and the third branch pipe 530 are equipped with control valves to control the gas flow direction. When it is necessary to heat the outdoor gas, the control valve on the first branch pipe 510 drives the hot gas flow through the second connecting pipe 512 into the third branch pipe 530. The control valve in the second branch pipe 520 drives the cold gas flow through the fourth connecting pipe 522 to discharge. When it is necessary to cool the outdoor gas, the control valve on the second branch pipe 520 delivers the cold gas flow through the second branch pipe 520 and the third connecting pipe 521 to the third branch pipe 530. The control valve in the first branch pipe 510 controls the hot gas flow to enter the outer pipe 400 through the first connecting pipe 511 to heat the gas in the inner pipe 401.

[0042] See Figure 10 and Figure 11 A fixed plate 412 is fixedly connected to the side of the compression pipe 410 near the outer pipe 400, and a sliding plate 411 is slidably connected to the side of the compression pipe 410 away from the outer pipe 400. A first passage pipe 413 for gas passage is installed on both the sliding plate 411 and the fixed plate 412. A first one-way valve for controlling the gas flow direction is installed in the first passage pipe 413. The first one-way valve controls the gas to enter the inner pipe 401 through the compression pipe 410.

[0043] A fixing bracket 430 is fixedly connected to the side of the compression pipe 410 away from the fixing plate 412. An electric telescopic rod 431 is fixedly connected to the side of the fixing bracket 431. The telescopic end of the electric telescopic rod 431 is fixedly connected to one end of the sliding plate 411. A control sleeve 432 is fixedly connected to the side of the fixing plate 412 near the sliding plate 411. A second piston plate 433 is slidably connected to the inner wall of the control sleeve 432. A second spring 434 is fixedly connected between the second piston plate 433 and the inner wall of the control sleeve 432. A trigger switch 435 is installed on the inner wall of one side of the control sleeve 432. The trigger switch 435 is electrically connected to the electric telescopic rod 431. A first one-way valve is located in the first through pipe 413 on the fixing plate 412. The valve is electrically connected to the electric telescopic rod 431. When gas enters the space between the sliding disc 411 and the fixed disc 412 through the first through pipe 413 on the sliding disc 411, the gas can compress the second piston plate 433 in the control sleeve 432. The second piston plate 433 slides under compression. When the gas pressure in the inner tube 401 reaches the threshold, the second piston plate 433 contacts the trigger switch 435, and the electric telescopic rod 431 starts to drive the sliding disc 411 to slide in the compression pipe 410, which can compress the gas between the sliding disc 411 and the fixed disc 412. At the same time, the first one-way valve at the fixed disc 412 opens, and the gas can be transported to the inner tube 401 through the compression pipe 410.

[0044] See Figure 9 A fixed sleeve 421 is installed inside the control tube 420. A first piston plate 422 is slidably connected to the inner wall of the fixed sleeve 421, and a sealing rod 423 is fixedly connected to one side of the fixed sleeve 421. The sealing rod 423 is slidably connected to the inner side of the first piston plate 422. A damping rod 424 and a first spring 425 are fixedly connected between the first piston plate 422 and the fixed sleeve 421. The first spring 425 resets the first piston plate 422, and the damping rod 424 reduces the moving speed of the first piston plate 422 during reset, preventing... To prevent incomplete exhaust of internal gas and the first piston plate 422 from resetting and blocking, thus affecting gas passage, a plurality of second passage pipes 426 arranged in a circular pattern are installed at one end of the fixed sleeve 421. A second one-way valve is installed inside the second passage pipe 426. When the gas in the inner tube 401 enters the control tube 420, the gas can squeeze the first piston plate 422. When the first piston plate 422 moves out of the blocking rod 423, the gas can pass through the first piston plate 422 and be transported to the adjacent inner tube 401 through the second passage pipe 426.

[0045] See Figure 5 and Figure 6The second heat exchange assembly includes a second heat exchange tube 700 and a mounting column 710. The mounting column 710 is fixedly connected to the outer wall of one side of the longitudinal plate 321. The second heat exchange tube 700 is spirally wrapped around the outer wall of the mounting column 710. One end of the second heat exchange tube 700 is connected to the third branch pipe 530, and the other end of the second heat exchange tube 700 passes through the longitudinal plate 321 and is connected to the first air inlet chamber. The gas in the third branch pipe 530 enters the second heat exchange tube 700, and the second heat exchange tube 700 can heat or cool the gas in the heat exchange chamber. After the gas in the second heat exchange tube 700 has completed heat exchange, it can enter the first air inlet chamber, pass through the heat exchange chamber again, and be discharged into the room through the fourth air pipe 113.

[0046] See Figure 12 The humidification assembly includes a humidification chamber 600 and an atomizer 620. The humidification chamber 600 is installed on the side of the horizontal plate 320 near the heat exchange chamber. A partition plate 610 is fixedly connected to the middle of the inner side of the humidification chamber 600. The partition plate 610 is inclined. A connecting pipe 601 is installed on one side of the humidification chamber 600. The connection point between the connecting pipe 601 and the inner side of the humidification chamber 600 is located at the top of the partition plate 610. The atomizer 620 is installed at the bottom of the inner side of the humidification chamber 600. A water inlet pipe 621 is installed on the top of the outer wall of the atomizer 620. The water inlet pipe 621 is fixedly connected to the partition plate 610. The inner wall of the humidifier 620 has a spray channel installed at its output end. The channel opening is located on the outer wall of the humidification chamber 600. The fourth connecting pipe 522 is connected to the top of the inner side of the humidification chamber 600. When the cold air is delivered to the humidification chamber 600 through the fourth connecting pipe 522, the gas in the heat exchange chamber enters the humidification chamber 600 through the connecting pipe 601. The cold air can liquefy the water vapor in the gas. The liquefied water enters the atomizer 620 through the water inlet pipe 621. The atomizer 620 atomizes the water and sprays it, which can increase the humidity of the air entering the room.

[0047] See Figure 3 The first heat exchange assembly includes a guide plate 210 and a first heat exchange tube 220. Both ends of the outer walls on both sides of the heat exchange box 200 are provided with air inlet slots. The guide plate 210 is installed at the slots at both ends of the inner side of the heat exchange box 200. A through fixing hole is provided on the guide plate 210. Both ends of the first heat exchange tube 220 are installed in the fixing holes on the guide plate 210. Both ends of the first heat exchange tube 220 are connected to the slots near the fourth chamber and the first chamber, respectively. The first heat exchange tube 220 is spiral-shaped. The gas in the chamber can enter the heat exchange box 200 through the fourth chamber and then enter the first chamber through the heat exchange box 200. The gas outside can enter the heat exchange box 200 through the second chamber and then enter the third chamber through the slot on the other side of the heat exchange box 200. The gas in the chamber can exchange heat with the gas outside entering the heat exchange box 200 in the first heat exchange tube 220.

[0048] The working principle of this invention is as follows: When ventilation is required, the two vortex fans 121 are activated. One vortex fan 121 drives the indoor gas through the third air pipe 112 into the fourth chamber of the ventilation box 100, and the other vortex fan 121 drives the outdoor gas through the first air pipe 110 into the second chamber of the ventilation box 100. The indoor gas passes through the first heat exchange pipe 220 into the first chamber and is discharged through the second air pipe 111. The outdoor gas passes through the heat exchange box 200 into the third chamber. The indoor gas in the first heat exchange pipe 220 can exchange heat with the outdoor gas entering the heat exchange box 200.

[0049] The gas entering the third chamber passes through the inlet 310 and the inlet pipe 311 into the first and second inlet chambers of the control box 300. The gas in the first inlet chamber enters the heat exchange chamber through the through hole and is discharged into the room through the through hole on the other side and the fourth gas pipe 113. The gas in the second inlet chamber enters between the sliding plate 411 and the fixed plate 412 through the first through pipe 413 on the sliding plate 411. The second piston plate 433 slides towards the trigger switch 435 under the action of air pressure. When the air pressure reaches the threshold, the second piston plate 433 contacts the trigger switch 435, and the electric telescopic rod 431 opens, driving the sliding plate 411 to slide closer to the fixed plate 412. At this time, the gas passes through the fixed plate 412. The first through-pipe 413 enters the inner pipe 401, and the gas in the inner pipe 401 can enter the control pipe 420 to compress the first piston plate 422. The first piston plate 422 is compressed by the gas and moves. When the gas pressure in the inner pipe 401 reaches the threshold, the first piston plate 422 slides out of the blockage of the sealing rod 423, and the gas can pass through the inner wall of the first piston plate 422 and the second through-pipe 426 to enter the adjacent inner pipe 401. By repeating this process, the gas can be gradually compressed. The compressed gas enters the vortex tube 500 through the nozzle 504. The compressed gas accelerates and expands in the vortex tube 500, forming a high-speed rotating vortex field, which is divided into hot gas flow and cold gas flow, and discharged through the hot flow outlet 503 and the cold flow outlet 502 respectively.

[0050] In summer, through the control valves in the first branch pipe 510 and the second branch pipe 520, the cold air flows through the cold air outlet 502 and the third connecting pipe 521 into the third branch pipe 530. The third branch pipe 530 delivers the cold air to the second heat exchange tube 700, where the gas in the heat exchange chamber can exchange heat with the cold air in the second heat exchange tube 700. After the heat exchange is completed, the gas is discharged into the room through the fourth gas pipe 113. The hot air flows through the first connecting pipe 511 into the outer pipe 400, heating the gas in the inner pipe 401. The gas expands due to the heat, improving the gas compression efficiency.

[0051] In winter, hot air flows through the first branch pipe 510 and the second connecting pipe 512 into the third branch pipe 530, and then through the second heat exchange pipe 700 to exchange heat with the gas in the heat exchange chamber. Cold air flows through the fourth connecting pipe 522 into the humidification chamber 600, liquefying the gas that enters the humidification chamber 600 through the connecting pipe 601. The condensate flows through the water inlet pipe 621 into the atomizer 620, which atomizes the water and sprays it out, increasing the humidity of the air entering the room.

[0052] When this invention is used, the second heat exchange component, the extrusion component and the vortex tube 500 can exchange heat with the gas entering the room, maintain the temperature of the gas entering the room, and avoid excessive temperature difference between the indoor and outdoor areas, which would affect the comfort of the people inside.

[0053] The first heat exchange component allows for heat exchange between outdoor and indoor air, reducing the temperature difference between them and preventing sudden temperature changes caused by excessive temperature differences, which could affect the comfort of indoor occupants.

[0054] By using the extrusion and docking components, the gas inside the inner tube 401 can be heated, increasing the gas volume, improving the gas compression efficiency, and enhancing the cooling and heating effect of the vortex tube 500.

[0055] By incorporating humidifying and connecting components, the humidity of the air entering the room can be increased during winter, preventing excessive dryness from affecting the comfort of indoor occupants.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
