Description

TECHNICAL FIELD

[0001] The present application relates to the field of tunnel system noise reduction cooling technology, in particular to a noise reduction ventilation cooling device and a tunnel system. BACKGROUND

[0002] In a subway station and other tunnel systems, there are electrical and mechanical facilities such as power supply equipment and central air conditioning equipment. These electrical and mechanical facilities generate a large amount of heat and noise when they are running. Cooling towers, ventilation devices and other heat dissipation and ventilation facilities are needed to dissipate heat and ventilate the internal environment of the tunnel system. However, the cooling tower also generates a large amount of noise when it is working. The staff of the subway station will suffer from hearing fatigue, headache, tinnitus and other symptoms due to long-term exposure to noise. Therefore, a noise reduction device needs to be installed inside the tunnel system. In the traditional tunnel system, the noise reduction device is often independently arranged with the cooling tower, ventilation device and other heat dissipation and ventilation facilities, resulting in poor overall noise reduction effect of the tunnel system, and the noise reduction device and the heat dissipation and ventilation facilities occupy a large tunnel space. SUMMARY

[0003] Therefore, it is necessary to provide a noise reduction ventilation cooling device and a tunnel system to solve the problem of poor overall noise reduction effect of the traditional tunnel system and the problem that the noise reduction device and the heat dissipation and ventilation facilities occupy a large tunnel space.

[0004] The present application provides a noise reduction ventilation cooling device, comprising:

[0005] A ventilation and noise reduction assembly, the ventilation and noise reduction assembly comprises a first shell and a sound absorbing piece, the first shell is provided with a first air inlet, a ventilation cavity and a second air inlet for communicating with the inside of the tunnel system, the sound absorbing piece forms part of the cavity wall of the ventilation cavity, the first air inlet is used for communicating the outside with the ventilation cavity, the sound absorbing piece is provided with at least two sound absorbing through holes, all the sound absorbing through holes are arranged at intervals, the ventilation cavity is communicated with the second air inlet through part of the sound absorbing through holes, and the noise reduction ventilation cooling device communicates the outside with the inside of the tunnel system through the ventilation and noise reduction assembly to ventilate and exchange air between the outside and the inside of the tunnel system.

[0006] The cooling assembly comprises a second shell, a blast pipe and a heat exchange loop, the second shell is arranged in the ventilation cavity, the second shell is provided with a cooling cavity which is communicated with the ventilation cavity and the sound insulation hole of the sound insulation member, the blast pipe is arranged at one end of the sound insulation member away from the ventilation cavity, one end of the blast pipe is communicated with the cooling cavity through the sound insulation hole of the sound insulation member, and the other end of the blast pipe is used for communicating the outside and / or the inside of the tunnel system, the heat exchange loop is internally circulated with a heat exchange medium, part of the heat exchange loop is arranged in the electromechanical facilities of the tunnel system so that the heat exchange medium absorbs the heat generated by the electromechanical facilities of the tunnel system, and part of the heat exchange loop is arranged in the cooling cavity so that the heat exchange medium releases heat to the cooling cavity, and the cooling assembly is used for communicating the cooling cavity with the outside and / or the inside of the tunnel system, so that the air of the outside or the air of the inside of the tunnel system carries away the heat released by the heat exchange medium in the cooling cavity.

[0007] In the ventilation and noise reduction assembly, the air of the outside can enter the inside of the tunnel system through the first air inlet, the ventilation cavity, the sound insulation hole of the sound insulation member and the second air inlet in sequence, so that the inside of the tunnel system can be communicated with the outside through the ventilation and noise reduction assembly, the air of the outside can enter the inside of the tunnel system through the ventilation and noise reduction assembly, or the air in the inside of the tunnel system can be discharged to the outside through the ventilation and noise reduction assembly, so as to realize ventilation and air exchange between the outside and the inside of the tunnel system; in the process of ventilation and air exchange, the air passes through the sound insulation hole of the sound insulation member, and the noise generated in the process of ventilating the inside of the tunnel system is absorbed by using the sound insulation effect of the sound insulation member, so as to reduce the ventilation noise; compared with the traditional way of independently arranging the noise reduction device and the ventilation device in the tunnel system, the noise reduction and ventilation cooling device arranges the sound insulation member close to the first air inlet communicated with the outside, which is beneficial to reduce the noise when the air enters or discharges the tunnel system, so as to reduce the noise at the source and enhance the overall noise reduction effect of the tunnel system, thereby reducing the overall noise of the tunnel system.

[0008] In the cooling assembly, the first air inlet, the ventilation cavity, the cooling cavity, the sound reduction through hole of the sound reduction member, and the air supply pipe member are sequentially communicated, and the first air inlet is used to communicate with the outside, and the air supply pipe member is used to communicate with the outside and / or the inside of the tunnel system. In this way, the air from the outside or the air from the inside of the tunnel system can flow between the first air inlet, the ventilation cavity, the cooling cavity, the sound reduction through hole of the sound reduction member, and the air supply pipe member, so that the heat released by the heat exchange medium in the cooling cavity can be taken away by the air from the outside or the air from the inside of the tunnel system. Generally, the high temperature generated by the electromechanical facilities of the tunnel system is higher than the temperature of the air from the outside or the air from the inside of the tunnel system. After the heat exchange medium absorbs the heat generated by the electromechanical facilities of the tunnel system, the temperature of the heat exchange medium is also higher than the temperature of the air from the outside or the air from the inside of the tunnel system. In this way, when the air from the outside or the air from the inside of the tunnel system flows through the cooling cavity, the temperature of the heat exchange medium is higher than the temperature of the air in the cooling cavity, so that the heat exchange medium releases heat to the cooling cavity, the air flowing through the cooling cavity takes away the released heat, the temperature of the heat exchange medium decreases, and the heat exchange medium after cooling circulates along the heat exchange loop to the electromechanical facilities of the tunnel system to continue to absorb the heat generated by the electromechanical facilities of the tunnel system to continue to cool the electromechanical facilities of the tunnel system. Therefore, the cooling assembly realizes the cooling function of the electromechanical facilities of the tunnel system. In the cooling process, since the cooling cavity is arranged in the ventilation cavity and the heat exchange medium of the heat exchange loop is cooled in the cooling cavity, the sound reduction member on the cavity wall of the ventilation cavity can absorb the noise generated when the heat exchange medium of the heat exchange loop is cooled. In this way, the cooling assembly can cool the electromechanical facilities and maintain a low noise level. Compared with the traditional cooling tower which generates a large amount of noise when working, the cooling assembly is beneficial to reduce the overall noise of the tunnel system, thereby reducing the impact of noise on the health of the staff in the subway station.

[0009] In addition, compared with the traditional tunnel system in which the noise reduction device, the cooling tower, and the ventilation device are independently arranged, the noise reduction, ventilation, and cooling are integrated into one device, which is equivalent to a combination of noise reduction, ventilation, and cooling. The sound reduction member is used to reduce noise during the ventilation process and the cooling process. In this way, the tunnel space occupied by the noise reduction, ventilation, and cooling device can be reduced, and the problem of large tunnel space occupied by the noise reduction device and the heat dissipation and ventilation facility in the traditional technical solution can be solved.

[0032] In an embodiment, a noise reduction ventilation cooling device 10, please refer to 1 to Figure 4 , comprising a ventilation noise reduction assembly 100 and a cooling assembly 200, the ventilation noise reduction assembly 100 comprises a first shell (not shown) and a silencer 130, the first shell is provided with a first air inlet 110, a ventilation cavity 120 and a second air inlet (not shown) for communicating with the inside of the tunnel system, the silencer 130 forms part of the cavity wall of the ventilation cavity 120, the first air inlet 110 is used to communicate with the outside and the ventilation cavity 120, the silencer 130 is provided with at least two sound reduction holes 131, all sound reduction holes 131 are arranged at intervals, the ventilation cavity 120 communicates with the second air inlet through part of the sound reduction holes 131, the noise reduction ventilation cooling device 10 communicates with the outside and the inside of the tunnel system through the ventilation noise reduction assembly 100 to ventilate and exchange air between the outside and the inside of the tunnel system;

[0033] The cooling assembly 200 comprises a second shell (not shown), an air supply pipe (not shown) and a heat exchange loop 220. The second shell is arranged in the ventilation cavity 120 and is provided with a cooling cavity 210 which is in communication with the ventilation cavity 120 and the rest of the sound-absorbing through hole 131. The air supply pipe is arranged at the end of the sound-absorbing member 130 away from the ventilation cavity 120. One end of the air supply pipe is in communication with the cooling cavity 210 through the rest of the sound-absorbing through hole 131. The other end of the air supply pipe is used to communicate with the outside and / or the inside of the tunnel system. The heat exchange loop 220 is internally circulated with a heat exchange medium (not shown). Part of the heat exchange loop 220 is arranged in the electromechanical facilities of the tunnel system so that the heat exchange medium absorbs the heat generated by the electromechanical facilities of the tunnel system. Part of the heat exchange loop 220 is arranged in the cooling cavity 210 so that the heat exchange medium releases heat to the cooling cavity 210. The cooling assembly 200 is used to communicate the cooling cavity 210 with the outside and / or the inside of the tunnel system so as to use the air outside or the air inside the tunnel system to take away the heat released by the heat exchange medium in the cooling cavity 210.

[0034] In the ventilation and noise reduction assembly 100, the air outside can enter the inside of the tunnel system through the first air inlet 110, the ventilation cavity 120, the sound-absorbing through hole 131 of the sound-absorbing member 130 and the second air inlet in sequence. Thus, the inside of the tunnel system can be communicated with the outside through the ventilation and noise reduction assembly 100. The air outside can enter the inside of the tunnel system through the ventilation and noise reduction assembly 100 or the air inside the tunnel system can be discharged to the outside through the ventilation and noise reduction assembly 100, so as to realize ventilation and air exchange between the outside and the inside of the tunnel system. In the process of ventilation and air exchange, the air passes through the sound-absorbing through hole 131 of the sound-absorbing member 130 and the noise generated in the process of ventilating the inside of the tunnel system is absorbed by the sound-absorbing effect of the sound-absorbing member 130, so as to reduce the ventilation noise. Compared with the conventional way of independently arranging the noise reduction device and the ventilation device in the tunnel system, the noise reduction ventilation and cooling device 10 arranges the sound-absorbing member 130 close to the first air inlet 110 which is in communication with the outside, which is conducive to reducing the noise when the air enters or is discharged from the tunnel system, so as to reduce the noise at the source and enhance the overall noise reduction effect of the tunnel system, thereby reducing the overall noise of the tunnel system.

[0035] In the cooling assembly 200, the first air inlet 110, the ventilation cavity 120, the cooling cavity 210, the sound reduction through hole 131 of the sound reduction member 130, and the air supply pipe member are sequentially communicated, and the first air inlet 110 is used to communicate with the outside, and the air supply pipe member is used to communicate with the outside and / or the inside of the tunnel system. In this way, the air from the outside or the air from the inside of the tunnel system can flow between the first air inlet 110, the ventilation cavity 120, the cooling cavity 210, the sound reduction through hole 131 of the sound reduction member 130, and the air supply pipe member, so that the air from the outside or the air from the inside of the tunnel system can take away the heat released by the heat transfer medium in the cooling cavity 210. Generally, the high temperature generated by the electromechanical facilities of the tunnel system is higher than the temperature of the air from the outside or the air from the inside of the tunnel system. After the heat transfer medium absorbs the heat generated by the electromechanical facilities of the tunnel system, the temperature of the heat transfer medium is also higher than the temperature of the air from the outside or the air from the inside of the tunnel system. In this way, when the air from the outside or the air from the inside of the tunnel system flows through the cooling cavity 210, the temperature of the heat transfer medium is higher than the temperature of the air in the cooling cavity 210, so that the heat transfer medium releases heat to the cooling cavity 210, the air flowing through the cooling cavity 210 takes away the released heat, the temperature of the heat transfer medium decreases, and the heat transfer medium after cooling circulates along the heat transfer loop 220 to the electromechanical facilities of the tunnel system to continue to absorb the heat generated by the electromechanical facilities of the tunnel system to continue to cool the electromechanical facilities of the tunnel system. Therefore, the cooling assembly 200 realizes the cooling function of the electromechanical facilities of the tunnel system. In the cooling process, since the cooling cavity 210 is arranged in the ventilation cavity 120 and the heat transfer medium of the heat transfer loop 220 is cooled in the cooling cavity 210, the sound reduction member 130 on the cavity wall of the ventilation cavity 120 can absorb the noise generated when the heat transfer medium of the heat transfer loop 220 is cooled. In this way, the cooling assembly 200 can cool the electromechanical facilities and maintain a low noise level. Compared with the traditional cooling tower which generates a large amount of noise during operation, the cooling assembly 200 is beneficial to reduce the overall noise of the tunnel system, thereby reducing the impact of noise on the health of the staff in the subway station.

[0036] In addition, compared with the traditional tunnel system in which the noise reduction device, the cooling tower, and the ventilation device are independently arranged, the noise reduction, ventilation, and cooling are integrated in the noise reduction ventilation cooling device 10, which is equivalent to a combined device for noise reduction, ventilation, and cooling. The sound reduction member 130 is used to reduce noise during the ventilation process and the cooling process. In this way, the tunnel space occupied by the noise reduction ventilation cooling device 10 can be reduced, and the problem of large tunnel space occupied by the noise reduction device and the heat dissipation ventilation facility in the traditional technical solution can be solved.

[0037] Optionally, the first shell can be a metal shell, a plastic shell, or a composite material shell.

[0038] Optionally, the second shell can be a metal shell, a plastic shell, or a composite material shell.

[0039] Optionally, the ventilation and noise reduction assembly 100 further comprises a first pipe (not shown) for connecting the first air port 110 and the ventilation cavity 120.

[0040] Optionally, the ventilation and noise reduction assembly 100 further comprises a second pipe (not shown) for connecting the partial sound reduction through hole 131 and the second air port.

[0041] Optionally, the sound reduction member 130 can be a sound reduction wall formed by sound reduction cotton, and at least two sound reduction through holes 131 are formed in the sound reduction wall.

[0042] In some embodiments, referring to Figure 1 , the air supply pipe is used to connect the outside and one end of the tunnel system interior, and comprises a first sub-air port (not shown) and a second sub-air port (not shown), the first sub-air port is used to communicate with the outside, and the second sub-air port is used to communicate with the tunnel system interior; the noise reduction ventilation cooling device 10 has an air intake state and an air exhaust state, in the air intake state, the first air port 110 serves as an air inlet of the noise reduction ventilation cooling device 10, the ventilation and noise reduction assembly 100 is used to send air from the outside to the tunnel system interior, the first sub-air port is opened, the second sub-air port is closed, and the cooling assembly 200 is used to connect the cooling cavity 210 and the outside to cool the heat exchange medium by using air from the outside; in the air exhaust state, the first air port 110 serves as an air outlet of the noise reduction ventilation cooling device 10, the ventilation and noise reduction assembly 100 is used to exhaust air from the tunnel system interior to the outside, the first sub-air port is closed, the second sub-air port is opened, and the cooling assembly 200 is used to connect the cooling cavity 210 and the tunnel system interior to cool the heat exchange medium by using air from the tunnel system interior.

[0043] In the air intake state, the first air port 110 serves as an air inlet of the noise reduction ventilation cooling device 10, in the ventilation and noise reduction assembly 100, air from the outside enters the ventilation cavity 120 from the first air port 110, and then passes through the sound reduction through hole 131 of the sound reduction member 130, the second air port, and reaches the tunnel system interior, and the second air port becomes an air outlet of the ventilation and noise reduction assembly 100, thereby, fresh air from the outside can be sent to the tunnel system interior to realize ventilation and air exchange of the tunnel system interior; at the same time, in the cooling assembly 200, air from the outside enters the ventilation cavity 120 from the first air port 110, and then passes through the cooling cavity 210, the sound reduction through hole 131 of the sound reduction member 130, the air supply pipe, and the first sub-air port in sequence, and finally is exhausted to the outside, thereby, fresh air from the outside is cooled after heat exchange with the heat exchange medium in the cooling cavity 210, and then is exhausted to the outside again, thereby, heat generated by the operation of the mechanical and electrical facilities of the tunnel system is removed to realize the cooling function.

[0044] In the air-out state, the first air port 110 serves as an air outlet of the noise-reducing ventilation cooling device 10. In the ventilation and noise reduction assembly 100, the gas inside the tunnel system passes through the second air port, the sound reduction through hole 131 of the sound reduction piece 130, the ventilation cavity 120, and then is discharged from the first air port 110 to the outside, so that the old gas and waste gas inside the tunnel system can be discharged, and ventilation of the tunnel system can be achieved. At the same time, in the cooling assembly 200, the gas inside the tunnel system passes through the second sub-air port, the air supply pipe piece, the sound reduction through hole 131 of the sound reduction piece 130, the cooling cavity 210, and the ventilation cavity 120, and then is discharged from the first air port 110 to the outside, so that the heat exchange medium in the cooling cavity 210 can be cooled by the gas inside the tunnel system, and the heat generated by the mechanical and electrical facilities of the tunnel system during operation can be taken away, and the cooling function can be achieved. The old gas and waste gas inside the tunnel system can be used. By setting the air-in and air-out states of the noise-reducing ventilation cooling device 10, the use flexibility of the noise-reducing ventilation cooling device 10 can be increased. The noise-reducing ventilation cooling device 10 can be used as an air-in section of the tunnel system to input fresh air into the tunnel system, or as an air-out section of the tunnel system to discharge old gas and waste gas from the tunnel system.

[0045] It is easy to understand that the use state of the noise-reducing ventilation cooling device 10 can be switched according to the real-time demand of the tunnel system. When more fresh air is needed inside the tunnel system, the noise-reducing ventilation cooling device 10 is set to the air-in state; when more old gas and waste gas needs to be discharged from the tunnel system, the noise-reducing ventilation cooling device 10 is set to the air-out state.

[0058] As can be easily understood, the second driving member 230 is arranged between the ventilation cavity 120 and the cooling cavity 210, when the second driving member 230 drives air to enter the cooling cavity 210 from the ventilation cavity 120, the air pressure in the cooling cavity 210 rises, and the air pressure difference between the cooling cavity 210 and the air supply pipe drives the air in the cooling cavity 210 to flow to the air supply pipe through the sound-reducing through hole 131 of the sound-reducing member 130, thereby achieving the flow of air from the first air inlet 110 to the air supply pipe; when the second driving member 230 drives air to enter the ventilation cavity 120 from the cooling cavity 210, the air pressure in the cooling cavity 210 decreases, and the air pressure difference between the air supply pipe and the cooling cavity 210 drives the air in the air supply pipe to flow to the cooling cavity 210 through the sound-reducing through hole 131 of the sound-reducing member 130, and then enters the ventilation cavity 120 and is discharged to the first air inlet 110, thereby achieving the flow of air from the air supply pipe to the first air inlet 110.

[0059] Optionally, the second driving member 230 can be a fan.

[0060] Preferably, the second driving member 230 is a second fan capable of forward and reverse rotation, in the air intake state of the noise-reducing ventilation cooling device 10, the second fan rotates in the second direction to deliver fresh air from the outside to the air supply pipe from the first air inlet 110; in the air outlet state of the noise-reducing ventilation cooling device 10, the second fan rotates in the reverse direction of the second direction to deliver air in the tunnel system from the air supply pipe to the first air inlet 110.

[0061] It is easily understood that, in the air intake state of the noise reduction ventilation cooling device 10, the rotating directions of the first fan and the second fan are coordinated with each other, so that the air outside can enter the first air inlet 110 under the joint action of the first fan and the second fan; in the air outlet state of the noise reduction ventilation cooling device 10, the rotating directions of the first fan and the second fan are coordinated with each other, so that the air inside the tunnel system can be discharged from the first air inlet 110 under the joint action of the first fan and the second fan.

[0062] In some embodiments, referring to Figure 3 , the cooling assembly 200 further comprises a filler 240 and a water distribution device (not shown), the filler 240 is wrapped around the part of the heat exchange loop 220 arranged in the cooling cavity 210, one end of the water distribution device is used to communicate with a water source (not shown), and the other end of the water distribution device is used to sprinkle water to the filler 240. In this way, the part of the heat exchange loop 220 arranged in the cooling cavity 210 can be cooled by the air flowing in the cooling cavity 210 on the one hand, and can also be cooled by the heat exchange between the water on the surface of the filler 240 and the heat exchange loop 220 on the other hand, and the air flowing in the cooling cavity 210 can also carry away the water vapor generated on the surface of the filler 240 due to the heating of the heat exchange loop 220, further enhancing the cooling capacity of the cooling assembly 200. It is easily understood that the filler 240 is used to provide a water adhesion surface, i.e. the surface of the filler 240 is the water adhesion surface, so as to increase the contact area and contact time of the water and the heat exchange loop 220, and enhance the heat absorption capacity of the water to the heat exchange loop 220.

[0063] Optionally, the cooling assembly 200 further comprises a water collecting tray (not shown), which is used to collect the water falling from the filler 240.

[0064] Optionally, the cooling assembly 200 further comprises a water return pipe (not shown), one end of the water return pipe is connected with the water collecting tray, and the other end of the water return pipe is used to communicate with the water source to return the water in the water collecting tray to the water source.

[0065] The tunnel system of one embodiment comprises the noise reduction ventilation cooling device 10 of any of the foregoing embodiments. In the tunnel system, when ventilation is performed, the air passes through the sound reduction holes 131 of the sound reduction member 130, and the noise generated during the ventilation of the tunnel system is absorbed by the sound reduction effect of the sound reduction member 130, thereby reducing the ventilation noise. Compared with the conventional tunnel system in which the noise reduction device and the ventilation device are independently arranged, the noise reduction ventilation cooling device 10 is arranged close to the first air inlet 110 that communicates with the outside, which is conducive to reducing the noise when the air enters or exits the tunnel system, thereby reducing the noise at the source to enhance the overall noise reduction effect of the tunnel system and reduce the overall noise of the tunnel system. When cooling is performed, since the cooling cavity 210 is arranged in the ventilation cavity 120 and the heat exchange medium of the heat exchange loop 220 is cooled in the cooling cavity 210, the sound reduction member 130 on the cavity wall of the ventilation cavity 120 can absorb the noise generated when the heat exchange medium of the heat exchange loop 220 is cooled. In this way, the cooling assembly 200 can cool the electromechanical facilities while maintaining a low noise level. Compared with the conventional cooling tower that generates a large amount of noise during operation, the cooling assembly 200 is conducive to reducing the overall noise of the tunnel system, thereby reducing the impact of noise on the health of the staff in the subway station. Compared with the conventional tunnel system in which the noise reduction device, the cooling tower, and the ventilation device are independently arranged, the noise reduction ventilation cooling device 10 integrates noise reduction, ventilation, and cooling, which is equivalent to a combined device for noise reduction, ventilation, and cooling. The sound reduction member 130 is used to reduce noise during ventilation and cooling, which is conducive to reducing the tunnel space occupied by the noise reduction ventilation cooling device 10 and solving the problem of large tunnel space occupied by the noise reduction device and the heat dissipation ventilation facility in the conventional technical solution.

[0066] In some embodiments, at least two noise reduction ventilation cooling devices 10 are provided, and the noise reduction ventilation cooling devices 10 are arranged at intervals. The provision of at least two noise reduction ventilation cooling devices 10 in the tunnel system can enhance ventilation and air exchange in the tunnel system and enhance cooling of the electromechanical facilities in the tunnel system, which is conducive to reducing the overall noise of the tunnel system.

[0067] In some embodiments, the noise reduction ventilation cooling device 10 has two use states of air intake and air exhaust, and the use state of each noise reduction ventilation cooling device 10 can be switched according to the real-time needs of the tunnel system. When more fresh air is needed in the tunnel system, more noise reduction ventilation cooling devices 10 are arranged in the air intake state, the number of noise reduction ventilation cooling devices 10 in the air intake state is increased, and the intake of fresh air is enhanced. When more old air or exhaust air needs to be exhausted from the tunnel system, more noise reduction ventilation cooling devices 10 are arranged in the air exhaust state, the number of noise reduction ventilation cooling devices 10 in the air exhaust state is increased, and the exhaust of air in the tunnel system is enhanced.
