Description

Technical Field

[0001] This invention relates to the field of chiller air volume control technology, specifically to a high-speed railway station chiller air volume control device and method based on environmental parameter self-adaptation. Background Technology

[0002] The high-speed railway station chiller air volume control device based on environmental parameters mainly uses fan coil units to precisely adjust the air supply volume of air conditioning in public areas such as waiting halls and platforms of high-speed railway stations. It can adjust the air supply volume in real time according to environmental needs to ensure the comfort and energy efficiency of the indoor environment of high-speed railway stations.

[0003] Patent CN222480625U discloses an easy-to-install fan coil unit, including a base, a support, an adjustment component, a chassis, a fan coil body, and an installation component. The installation component is located at the lower end of the fan coil body. By moving a fixed plate, a locking block is inserted into the chassis. At this time, the fixed plate abuts against the upper side of the chassis, and the locking block exerts a pushing force on a fixed ball. Under the action of a telescopic rod and a spring, the fixed ball generates a reaction force on the locking block, fixing it in place. This achieves the fixation of the fan coil body, which is convenient, quick, and time-saving. An adjustment component is located on the upper side of the base. By starting a motor, a second slider moves a lower slider, causing an outer connecting rod to move an inner connecting rod. This, in conjunction with the upper slider, allows the support to move up and down, adjusting the height of the fan coil body from the ground to meet different usage needs and improve the flexibility of the device.

[0004] However, the currently easy-to-install fan coil units have the following problems: when the fan coil unit is running in the subway station, the passenger flow in the high-speed rail station changes constantly during the fan coil unit's operation, making it difficult for the fan coil unit to adjust the air volume in real time according to environmental needs, which leads to unsuitable indoor temperature in the high-speed rail station. Therefore, we propose a high-speed rail station chiller air volume control device and method based on environmental parameter self-adaptation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device and method for regulating the air volume of chillers in high-speed railway stations based on adaptive environmental parameters, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed railway station chiller airflow control device based on adaptive environmental parameters, comprising a shroud and a fan coil unit. The shroud has three air chambers on its back, which are used to fan airflow into the fan coil unit. An air inlet is located on the left side of each air chamber, and an air outlet is located on the front. A circular rod is rotatably mounted through and on the right side of each air chamber. Three fan blades are fixed to the outer wall of the circular rod and are located inside the air chamber. A bracket is fixed to the right side of the back of the shroud, and a servo motor is fixedly mounted on the top surface of the bracket. The left side of the servo motor's shaft is fixedly connected to the right side of the circular rod. Two U-shaped perforated frames are fixed to the back of the shroud, and these U-shaped perforated frames are located within the three air chambers. Two I-shaped tubes are fixed to the outer wall of the round rod. The outer wall of the I-shaped tubes is rotatably connected to the inner wall of the U-shaped frame. An electric telescopic rod is fixed to the top of the back of the cover. A hole block is fixed to the back of the telescopic end of the electric telescopic rod. A U-shaped rod is fixed to the inner wall of the hole block. Two rubber rollers are fixed to the bottom of the U-shaped rod. The rubber rollers are used to slow down the rotation speed of the round rod. The rubber rollers press against the I-shaped tubes. Under the action of the extrusion force, the rotation speed of the I-shaped tubes slows down. The rotation speed of the round rod in the I-shaped tubes slows down, and the rotation speed of the fan blades on the round rod slows down, thus reducing the air volume of the air chamber. Conversely, when the telescopic end of the electric telescopic rod extends, the rubber rollers release the I-shaped tubes, and the rotation speed of the fan blades on the round rod increases, thus increasing the air volume of the air chamber.

[0007] According to the above technical solution, a fan coil unit is fixedly installed on the front of the hood, an air outlet mesh is provided on the front of the fan coil unit, a base frame is fixedly installed on the bottom of the fan coil unit, a cold pipe is fixedly installed through and on the top left side of the fan coil unit, a heat pipe is fixedly installed through and on the bottom left side of the fan coil unit, a temperature sensor is fixedly installed on the top surface of the fan coil unit, and the data cable on the back of the temperature sensor is fixedly connected to the top surface of the electric telescopic rod.

[0008] According to the above technical solution, two round holes are opened on the back of the machine cover, the electric telescopic rod is located above several air chambers, and the inner wall of the I-shaped tube is on the outer wall of the rubber roller.

[0009] According to the above technical solution, the outer wall of the U-shaped rod is provided with an anti-dust accumulation device, which is used to push away the floating dust accumulated at the upper air outlet. The front of the anti-dust accumulation device is provided with a moisture-proof device, which is used to reduce the moisture inside the fan coil unit.

[0010] According to the above technical solution, the anti-ash accumulation device includes two ring blocks, which are fixed on the outer wall of the U-shaped rod. Short pipes are fixed to the inner walls of the two round holes of the machine cover. An L-shaped rod is fixed to the back of the ring blocks. The outer wall of the L-shaped rod is slidably connected to the inner wall of the short pipe. A strip plate is fixed to the end of the L-shaped rod away from the ring blocks. The strip plate is located at the bottom front of the machine cover. Three L-shaped plates are fixed to the front of the strip plate. A mesh cover is installed on the front of the air outlet of the air chamber. The bottom front of the mesh cover is on the movement trajectory of the back of the L-shaped plate. When the telescopic end of the electric telescopic rod extends backward, the L-shaped plate pushes against the mesh surface of the mesh cover backward, causing the mesh surface of the mesh cover to become arc-shaped.

[0011] According to the above technical solution, a ring block is fixed to the bottom of the outer wall of the L-shaped rod, a spring is fixed to the back of the ring block, a square plate is fixed to the end of the spring away from the ring block, the square plate is fixed to the front of the machine cover, the ring block is used to stretch and compress the spring, and under the action of the spring force, the spring force is used to reduce the shaking of the L-shaped rod.

[0012] According to the above technical solution, the moisture-proof device includes two curved plates, which are fixed to the front of the ring block. A U-shaped long frame is fixed to the bottom of the back of the curved plates. A calcium chloride column is rotatably installed through the inner wall of the U-shaped long frame. Wheels are fixed to the left and right sides of the rotating shaft of the calcium chloride column. Two strips are fixed to the bottom of the front of the machine cover. The outer wall of the wheel rolls in contact with the top surface of the strip. The wheel rolls on the strip and drives the calcium chloride column to rotate. The calcium chloride column rotates in the U-shaped long frame, so that the calcium chloride column comes into large-area contact with the airflow in the fan coil unit during the rotation.

[0013] According to the above technical solution, two groove blocks are fixed on the top surface of the U-shaped long frame, and T-shaped sliders are slidably installed on the inner wall of the groove blocks. A strip mesh is fixedly installed on the top surface of the T-shaped slider. The strip mesh is used to reduce floating dust falling onto the surface of the calcium chloride column. The T-shaped slider drives the strip mesh to move forward, and the strip mesh blocks floating dust from contacting the surface of the calcium chloride column.

[0014] A method for using a high-speed railway station chiller air volume control device based on adaptive environmental parameters includes the following steps:

[0015] S1. The fan blades drive the airflow into the air outlet of the air chamber, and the airflow enters the fan coil unit;

[0016] S2. The cold pipe cools the airflow, and the heat brought in by the airflow is discharged through the heat pipe. The fan blows out cold air into the high-speed rail station.

[0017] S3. When the rubber roller presses against the I-shaped tube, the rotation speed of the fan blades on the round rod slows down, the air volume of the air chamber decreases, and when the rubber roller releases the I-shaped tube, the air volume of the air chamber increases.

[0018] S4. The L-shaped plate pushes back against the mesh surface of the mesh cover, causing the mesh surface of the mesh cover to become arc-shaped;

[0019] S5. The spring force reduces the jitter of the L-shaped rod during its movement.

[0020] S6. The calcium chloride column rotates in the U-shaped long frame, so that the calcium chloride column comes into large contact with the airflow in the fan coil unit during the rotation process.

[0021] S7. The T-shaped slider moves the strip mesh forward, and the strip mesh prevents floating dust from contacting the surface of the calcium chloride column.

[0022] This invention provides a high-speed railway station chiller airflow control device based on adaptive environmental parameters. It has the following beneficial effects:

[0023] (1) The present invention uses a cover, a wind chamber, a round rod, fan blades, a U-shaped frame, an I-shaped tube, a support, a servo motor, an electric telescopic rod, a hole block, a U-shaped rod, a rubber roller, a base frame, and a fan coil unit in conjunction with a temperature sensor. The rubber rollers press against the I-shaped tube. Under the action of the extrusion force, the rotation speed of the I-shaped tube slows down, the rotation speed of the round rod in the I-shaped tube slows down, and the rotation speed of the fan blades on the round rod slows down, thus reducing the air volume of the wind chamber. Conversely, the telescopic end of the electric telescopic rod extends, the rubber rollers loosen the I-shaped tube, and the rotation speed of the fan blades on the round rod increases, thus increasing the air volume of the wind chamber. This allows the temperature sensor to adjust the air volume of the wind chamber in real time according to the temperature of the high-speed railway station, preventing the equipment from being unable to adjust the air volume of the wind chamber in real time according to the passenger flow of the station, which would cause the indoor temperature of the high-speed railway station to be unsuitable.

[0024] (2) By setting up an anti-dust accumulation device, the present invention enables the ring block, short pipe, L-shaped rod, strip plate and L-shaped plate to cooperate with the mesh cover. When the telescopic end of the electric telescopic rod extends backward, the L-shaped plate pushes against the mesh surface of the mesh cover backward, so that the mesh surface of the mesh cover becomes arc-shaped. The floating dust falls off from the gaps in the mesh surface, so that the gaps in the mesh surface of the mesh cover will not be covered with a large amount of floating dust, thus preventing the poor air outlet effect of the wind chamber caused by a large amount of floating dust adhering to the gaps in the mesh surface of the mesh cover.

[0025] (3) By setting up an anti-ash accumulation device, the circular block and the spring cooperate with the square plate to reduce the shaking during the movement of the L-shaped rod under the elastic force of the spring, and prevent the L-shaped rod from shaking violently and causing unstable operation of the equipment.

[0026] (4) The present invention, through the setting of the moisture-proof device, makes the curved plate, U-shaped long frame, calcium chloride column and round wheel cooperate with the frame. The round wheel rolls on the frame and drives the calcium chloride column to rotate. The calcium chloride column rotates in the U-shaped long frame, so that the calcium chloride column comes into contact with the airflow in the fan coil machine in a large area during the rotation process. The calcium chloride column quickly absorbs the moisture in the fan coil machine and prevents the equipment from being damaged by moisture due to a large amount of moisture in the fan coil machine.

[0027] (5) The present invention uses a moisture-proof device to make the trough block and the T-shaped slider work together with the strip mesh. The T-shaped slider drives the strip mesh to move forward, and the strip mesh blocks the floating dust from contacting the surface of the calcium chloride column, thus preventing the floating dust from adhering to the surface of the calcium chloride column and causing poor dehumidification effect of the equipment.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Please see Figures 1-9One embodiment of the present invention is: a high-speed railway station chiller air volume control device based on environmental parameter adaptive design, comprising a cover 1 and a fan coil unit 14. The back of the cover 1 has three air chambers 2, which are used to fan airflow into the fan coil unit 14. An air inlet is opened on the left side of each air chamber 2, and an air outlet is opened on the front side. A circular rod 3 is rotatably mounted through the right side of the air chamber 2. Three fan blades 4 are fixed to the outer wall of the circular rod 3, located inside the air chamber 2. A bracket 7 is fixed to the right side of the back of the cover 1, and a servo motor 8 is fixedly mounted on the top surface of the bracket 7. The left side of the rotating shaft of the servo motor 8 is fixedly connected to the right side of the circular rod 3. The rotating shaft of the servo motor 8 drives the circular rod 3 to rotate clockwise. The circular rod 3 rotates clockwise within the air chamber 2, and the circular rod 3 drives the fan blades 4 to rotate clockwise. When blade 4 rotates clockwise, the airflow enters through the air inlet of the air chamber 2 and is fanned by blade 4 into the air outlet of the air chamber 2. The airflow then enters the fan coil unit 14. Two U-shaped brackets 5 are fixed to the back of the cover 1, located between the three air chambers 2. Two I-shaped tubes 6 are fixed to the outer wall of the round rod 3, and their outer walls are rotatably connected to the inner walls of the U-shaped brackets 5. An electric telescopic rod 9 is fixed to the top of the back of the cover 1. A perforated block 10 is fixed to the back of the telescopic end of the electric telescopic rod 9. A U-shaped rod 11 is fixed to the inner wall of the perforated block 10. Two rubber rollers 12 are fixed to the bottom of the U-shaped rod 11 to slow down the rotation speed of the round rod 3. The fan coil unit 14 is fixed to the front of the cover 1. 4. The fan coil unit 14 has an air outlet mesh on its front. A base frame 13 is fixedly installed on the bottom of the fan coil unit 14. A cold pipe 141 is fixedly installed through the top left side of the fan coil unit 14, and a heat pipe 142 is fixedly installed through the bottom left side of the fan coil unit 14. A temperature sensor 15 is fixedly installed on the top surface of the fan coil unit 14. The cold pipe 141 cools the airflow, and the heat brought in by the airflow is discharged through the heat pipe 142, allowing the fan coil unit 14 to blow cold air into the high-speed rail station. The data cable on the back of the temperature sensor 15 is fixedly connected to the top surface of the electric telescopic rod 9. Two round holes are opened on the back of the cover 1. The electric telescopic rod 9 is located above several air chambers 2. The inner wall of the I-shaped tube 6 is on the outer wall of the rubber roller 12. The temperature sensor 15 passes through... When the electric telescopic rod 9 is started via the data cable, the rubber roller 12 presses against the I-shaped tube 6. Under the action of the extrusion force, the rotation speed of the I-shaped tube 6 slows down, the rotation speed of the round rod 3 in the I-shaped tube 6 slows down, and the rotation speed of the fan blade 4 on the round rod 3 slows down, thus reducing the air volume of the air chamber 2. Conversely, when the telescopic end of the electric telescopic rod 9 extends, the rubber roller 12 releases the I-shaped tube 6, and the rotation speed of the fan blade 4 on the round rod 3 increases, thus increasing the air volume of the air chamber 2. This allows the temperature sensor 15 to adjust the air volume of the air chamber 2 in real time according to the temperature of the high-speed railway station, avoiding the problem that the cold air volume control device cannot adjust the air volume of the air chamber 2 in real time according to the passenger flow in the high-speed railway station, which would cause the indoor temperature of the high-speed railway station to be unsuitable.

[0040] The outer wall of the U-shaped rod 11 is provided with an anti-dust accumulation device 16, which is used to push away the floating dust accumulated at the upper air outlet. The front of the anti-dust accumulation device 16 is provided with a moisture-proof device 17, which is used to reduce the moisture inside the fan coil unit 14.

[0041] Because the passenger flow in the high-speed rail station changes constantly during the operation of the fan coil unit 14, it is difficult for the fan coil unit 14 to adjust the air volume in real time according to environmental needs. When using this equipment, the base frame 13 supports the fan coil unit 14, which in turn supports the cover 1. The cold pipe 141 and heat pipe 142 on the fan coil unit 14 are connected to the outdoor unit of the central air conditioning system. The operator starts the servo motor 8 on the bracket 7. The shaft of the servo motor 8 begins to rotate forward, driving the round rod 3 to rotate forward. The round rod 3 rotates forward in the air chamber 2, driving the fan blades 4 to rotate forward. The fan rotates within the air chamber 2, with airflow entering through the air inlet. Fan blades 4 fan the airflow into the air outlet of the air chamber 2, where it enters the fan coil unit 14. Cooling pipes 141 cool the airflow, and the heat carried by the airflow is discharged through heat pipes 142, allowing the fan coil unit 14 to blow cool air into the high-speed rail station. Simultaneously, temperature sensor 15 senses the temperature inside the high-speed rail station. When there are fewer people inside the high-speed rail station, temperature sensor 15 detects a decrease in temperature and activates the electric telescopic rod 9 via a data cable. The telescopic end of the electric telescopic rod 9 begins to retract. The round rod 3 drives the I-shaped tube 6 to rotate. The I-shaped tube 6 rotates within the U-shaped frame 5. The telescopic end of the electric telescopic rod 9 drives the hole block 10 forward. The hole block 10 drives the U-shaped rod 11 forward. The U-shaped rod 11 drives the rubber roller 12 forward. During its forward movement, the rubber roller 12 contacts the I-shaped tube 6. Under the action of friction, the rubber roller 12 rolls within the I-shaped tube 6. Under the action of extrusion pressure, the rotational speed of the I-shaped tube 6 slows down. Consequently, the rotational speed of the round rod 3 within the I-shaped tube 6 slows down, and the rotational speed of the fan blade 4 on the round rod 3 also slows down. The airflow from the air chamber 2 is reduced, while the telescopic end of the electric telescopic rod 9 extends, the rubber roller 12 loosens the I-shaped tube 6, and the rotation speed of the fan blade 4 on the round rod 3 increases, thus increasing the airflow from the air chamber 2. This allows the temperature sensor 15 to adjust the airflow from the air chamber 2 in real time based on the temperature of the high-speed railway station. This prevents the equipment from being unable to adjust the airflow from the air chamber 2 in real time according to the passenger flow during use, thereby avoiding the problem of unsuitable indoor temperature in the high-speed railway station caused by the equipment's inability to adjust the airflow from the air chamber 2 in real time according to the passenger flow during use.

[0042] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the anti-ash accumulation device 16 includes two ring blocks 161, which are fixed to the outer wall of the U-shaped rod 11. Short pipes 162 are fixed to the inner walls of the two round holes of the machine cover 1. An L-shaped rod 163 is fixed to the back of the ring blocks 161. The outer wall of the L-shaped rod 163 is slidably connected to the inner wall of the short pipe 162. A strip plate 164 is fixed to the end of the L-shaped rod 163 away from the ring blocks 161. The strip plate 164 is located at the bottom of the front of the machine cover 1. Three L-shaped plates 165 are fixed to the front of the strip plate 164. A mesh cover 166 is installed on the front of the air outlet of the air chamber 2. The front bottom of 66 is on the movement trajectory of the back of L-shaped plate 165. The strip 164 drives L-shaped plate 165 to move forward. L-shaped plate 165 leaves the mesh cover 166. When the telescopic end of electric telescopic rod 9 extends backward, L-shaped plate 165 pushes against the mesh surface of mesh cover 166, causing the mesh surface of mesh cover 166 to become arc-shaped. Dust falls from the mesh gaps, preventing a large amount of dust from adhering to the mesh gaps of mesh cover 166. This avoids the poor air outlet effect of air chamber 2 caused by a large amount of dust adhering to the mesh gaps of mesh cover 166 during the use of the air volume control device in the high-speed railway station.

[0043] A ring block 167 is fixed to the bottom of the outer wall of the L-shaped rod 163. A spring 168 is fixed to the back of the ring block 167. A square plate 169 is fixed to the end of the spring 168 away from the ring block 167. The square plate 169 is fixed to the front of the cover 1. The ring block 167 is used to stretch and compress the spring 168. The elastic force of the spring 168 is used to reduce the vibration of the L-shaped rod 163. The spring 168 is stretched by the ring block 167. Under the action of the elastic force of the spring 168, the vibration of the L-shaped rod 163 during movement is reduced, so as to avoid the L-shaped rod 163 from vibrating violently and causing unstable operation of the equipment during the use of the air volume control device in the high-speed railway station.

[0044] The moisture-proof device 17 includes two curved plates 171, which are fixed to the front of the ring block 167. A U-shaped long frame 172 is fixed to the bottom of the back of the curved plate 171. A calcium chloride column 173 is rotatably installed through the inner wall of the U-shaped long frame 172. A round wheel 174 is fixed to the left and right sides of the rotating shaft of the calcium chloride column 173. Two strips 175 are fixed to the bottom of the front of the cover 1. The outer wall of the round wheel 174 rolls in contact with the top surface of the strip 175. Under the action of friction, the round wheel 174 rolls on the strip 175, and the round wheel 174 drives the calcium chloride column 173 to rotate. The calcium chloride column 173 rotates in the U-shaped long frame 172, so that the calcium chloride column 173 comes into large-area contact with the airflow in the fan coil unit 14 during the rotation. The calcium chloride column 173 quickly absorbs the moisture in the fan coil unit 14, avoiding the damage to the equipment caused by a large amount of moisture in the fan coil unit 14 during the use of the airflow control device in the high-speed railway station.

[0045] Two slots 176 are fixed to the top surface of the U-shaped long frame 172. T-shaped sliders 177 are slidably installed on the inner wall of the slots 176. A strip mesh 178 is fixedly installed on the top surface of the T-shaped sliders 177. The strip mesh 178 is used to reduce dust falling onto the surface of the calcium chloride column 173. The T-shaped sliders 177 drive the strip mesh 178 to move forward. The strip mesh 178 blocks dust from contacting the surface of the calcium chloride column 173, thus preventing dust from adhering to the surface of the calcium chloride column 173 and causing poor dehumidification effect of the equipment during the use of the chiller air volume control device in the high-speed railway station.

[0046] A method for using a high-speed railway station chiller air volume control device based on adaptive environmental parameters includes the following steps:

[0047] S1, the fan blades 4 fan the airflow into the air outlet of the air chamber 2, and the airflow enters the fan coil unit 14;

[0048] S2, the cold pipe 141 cools the airflow, and the heat brought in by the airflow is discharged through the heat pipe 142. The fan 14 blows out cold air into the high-speed rail station.

[0049] S3. When the rubber roller 12 presses against the I-shaped tube 6, the rotation speed of the fan blade 4 on the round rod 3 slows down, the air volume of the wind chamber 2 decreases, and the rubber roller 12 releases the I-shaped tube 6, and the air volume of the wind chamber 2 increases.

[0050] S4. The L-shaped plate 165 pushes back against the mesh surface of the mesh cover 166, causing the mesh surface of the mesh cover 166 to become arc-shaped.

[0051] S5. Under the elastic force of spring 168, reduce the shaking during the movement of L-shaped rod 163;

[0052] S6. The calcium chloride column 173 rotates in the U-shaped long frame 172, so that the calcium chloride column 173 comes into large-area contact with the airflow in the fan coil machine 14 during the rotation.

[0053] S7, T-shaped slider 177 drives strip mesh 178 to move forward, strip mesh 178 prevents floating dust from contacting the surface of calcium chloride column 173.

[0054] As the perforated block 10 moves the U-shaped rod 11 forward, the U-shaped rod 11 moves the ring block 161 forward, the ring block 161 moves the L-shaped rod 163 forward, the L-shaped rod 163 slides forward in the short pipe 162, the L-shaped rod 163 moves the strip 164 forward, the strip 164 moves the L-shaped plate 165 forward, the L-shaped plate 165 leaves the mesh cover 166, and when the telescopic end of the electric telescopic rod 9 extends backward, the L-shaped plate 165 pushes against the mesh surface of the mesh cover 166, causing the mesh surface of the mesh cover 166 to become arc-shaped, and the floating dust falls from the mesh surface gaps, so that the mesh surface gaps of the mesh cover 166 will not be covered with a large amount of floating dust. This prevents the mesh surface gaps of the mesh cover 166 from being covered with a large amount of floating dust during the use of the equipment, thus avoiding the problem of poor air outlet effect of the air chamber 2 caused by a large amount of floating dust attached to the mesh surface gaps of the mesh cover 166 during the use of the chiller air volume control device in the high-speed railway station.

[0055] While the ring block 161 drives the L-shaped rod 163 forward, the L-shaped rod 163 drives the ring block 167 forward, and the ring block 167 drives the spring 168 forward. Under the restriction of the square plate 169, the spring 168 is stretched by the ring block 167. Under the elastic force of the spring 168, the shaking of the L-shaped rod 163 during the movement is reduced, preventing the L-shaped rod 163 from shaking violently when moving during use. This avoids the problem of unstable operation of the equipment caused by the L-shaped rod 163 shaking violently during the use of the air volume control device in the high-speed railway station.

[0056] As the L-shaped rod 163 drives the ring block 167 forward, the ring block 167 drives the bent plate 171 forward, the bent plate 171 drives the U-shaped long frame 172 forward, the U-shaped long frame 172 drives the calcium chloride column 173 forward, and the calcium chloride column 173 drives the wheel 174 forward. Under the action of friction, the wheel 174 rolls on the frame 175, and the wheel 174 drives the calcium chloride column 173 to rotate. The calcium chloride column 173 rotates in the U-shaped long frame 172, so that the calcium chloride column 173 comes into large-area contact with the airflow in the fan coil unit 14 during the rotation. The calcium chloride column 173 quickly absorbs the moisture in the fan coil unit 14, preventing the fan coil unit 14 from having a large amount of moisture during use. This avoids the problem of the airflow control device being damaged by moisture in the fan coil unit 14 during use in the high-speed railway station.

[0057] As the bending plate 171 moves the U-shaped long frame 172 forward, the U-shaped long frame 172 moves the trough block 176 forward, the trough block 176 moves the T-shaped slider 177 forward, and the T-shaped slider 177 moves the strip mesh 178 forward. The strip mesh 178 blocks floating dust from contacting the surface of the calcium chloride column 173, preventing floating dust from adhering to the surface of the calcium chloride column 173 during use. This avoids the problem of poor dehumidification effect caused by floating dust adhering to the surface of the calcium chloride column 173 during the use of the chiller air volume control device in the high-speed railway station.

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.
