Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically to a prefabricated substation with a built-in temperature and humidity-linked heat dissipation system and its control method. Background Technology

[0002] The prefabricated substation with a built-in temperature and humidity-linked cooling system is a new type of power equipment that deeply integrates the traditional prefabricated substation with an intelligent temperature and humidity control cooling system. By integrating components such as temperature sensors, humidity sensors, intelligent controllers, cooling fans, and dehumidification modules (such as heaters or condensation dehumidification devices), it achieves real-time monitoring and coordinated adjustment of the internal environment (temperature and humidity) of the enclosure. This ensures that core electrical equipment such as transformers and switchgear operate under optimal conditions, extends equipment life, and reduces the failure rate.

[0003] When a prefabricated substation with a built-in temperature and humidity linkage cooling system is in operation, the air discharged from the substation contains a certain amount of heat. If this heat is not utilized, it will lead to heat waste. Moreover, in winter, the external ambient temperature is low, and the air entering the prefabricated substation needs to be heated before it can be input into the substation. Heating the air requires a lot of electrical energy. Therefore, a prefabricated substation with a built-in temperature and humidity linkage cooling system and its control method are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated substation with a built-in temperature and humidity linkage heat dissipation system and its control method, which solves the problems of wasted heat from exhaust air, high energy consumption for heating intake air in winter, and ineffective utilization of condensate in the operation of the prefabricated substation. Through waste heat recovery, temperature and humidity linkage control and water resource recycling, energy saving, consumption reduction and environmental protection are achieved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A prefabricated substation with a built-in temperature and humidity-linked heat dissipation system includes a prefabricated substation. The prefabricated substation internally houses a transformer room, a low-voltage room, and a high-voltage room. Air boxes are fixedly connected to the top and bottom of the prefabricated substation. Multiple conduits are fixedly connected to opposite sides of the two air boxes, and one end of each set of conduits is connected to the transformer room, low-voltage room, and high-voltage room. An installation cabinet is fixedly connected to the left side of the prefabricated substation. A humidifier, a dehumidifier, and a heat exchanger are fixedly connected to the inner wall of the installation cabinet. An air inlet pipe is fixedly connected to the left side of the station, and a fan and humidity sensor are installed on the air inlet pipe.

The cold pipe on the right is connected to the air inlet pipe... The system is indirectly connected by an air pipe three. Solenoid valves are installed on the two cold pipes, two air pipes two, one air pipe one, one air pipe three, the heat pipe on the right side, and the air outlet pipe. A temperature control mechanism is installed on the air box at the top. A controller for controlling the humidifier, dehumidifier, fan, humidity sensor, and the opening and closing of the solenoid valves is fixedly connected to the inner wall of the installation cabinet. The controller integrates a humidity analysis module. The input terminal of the humidity analysis module is connected to the humidity sensor signal, and the output terminal of the temperature and humidity analysis module is connected to the controller signal.

[0007] As a further description of the above technical solution:

[0008] The temperature control mechanism includes a temperature sensor. The bottom of the temperature sensor is fixedly connected to the air inlet pipe. The probe of the temperature sensor penetrates and extends into the interior of the air inlet pipe. The controller integrates a temperature analysis module. The output of the temperature sensor is connected to the temperature analysis module. An electric heating plate and a cooling chip are fixedly connected to the inner wall of the top air box. The inputs of the electric heating plate and the cooling chip are both connected to the controller. The heat absorption surface of the cooling chip is located inside the top air box, and the heat dissipation surface of the cooling chip penetrates and extends to the back of the top air box. A fan for cooling the cooling chip is located on the back of the top air box.

[0009] As a further description of the above technical solution:

[0010] The left end of the air intake pipe is fitted with a cylinder threaded to it, and a filter plate is fixedly connected to the inner wall of the cylinder.

[0011] As a further description of the above technical solution:

[0012] A pressure sensor is fixedly connected to the inner wall of the air intake pipe, and an alarm is fixedly connected to the inner wall of the mounting cabinet. The output end of the pressure sensor is connected to the alarm signal.

[0013] As a further description of the above technical solution:

[0014] The transformer substation has three cavities inside. The inner walls of the three cavities are connected to the top conduit. The inner walls of the three cavities are provided with evenly distributed air vents, which are connected to the transformer chamber, the low-voltage chamber, and the high-voltage chamber, respectively.

[0015] As a further description of the above technical solution:

[0016] A water tank is fixedly connected to the inner wall of the installation cabinet. The condensate pipe of the heat exchanger is connected to the water tank. A horizontal pipe is fixedly connected to the left side of the water tank. The left end of the horizontal pipe passes through and extends to the left side of the installation cabinet. A valve is installed on the horizontal pipe. A liquid filling pipe is fixedly connected to the top of the water tank and communicates with it. The top end of the liquid filling pipe is fixedly connected to the liquid filling port of the humidifier. A water pump is installed on the liquid filling pipe. The output end of the humidifier is connected to the controller signal, and the output end of the controller is connected to the water pump signal.

[0017] This invention also provides a control method for a prefabricated substation with a built-in temperature and humidity-linked heat dissipation system, applicable to the aforementioned prefabricated substation with a built-in temperature and humidity-linked heat dissipation system, comprising the following steps:

[0018] S1. When the work starts, the controller controls the fan to start, and the fan will draw outside air into the air intake pipe. When the air flows, the humidity sensor will detect the humidity of the air and send the detected data to the humidity analysis module.

[0019] S2. The humidity analysis module compares the real-time humidity with the set threshold humidity. If the real-time humidity is higher than the threshold humidity, the humidity analysis module will send an over-humidity signal to the controller. If the real-time temperature is lower than the threshold humidity, the humidity analysis module will send an under-humidity signal to the controller. If the real-time temperature is within the normal range, the humidity analysis module will send a normal humidity signal to the controller.

[0020] S3. After receiving the over-humidity signal, the controller will open the solenoid valves on the two cold pipes, the right hot pipe, and the gas pipe.

[0021] S4. Air will flow from the intake pipe into the left-side cold pipe, and the air will flow in the heat exchanger, eventually flowing into the dehumidifier from the right-side cold pipe.

[0022] S5. When air enters the dehumidifier, the controller will turn on the dehumidifier. The dehumidifier will dehumidify the air. The dehumidified air will enter the air inlet pipe through the air pipe and finally enter the top air box.

[0023] S6. After the dehumidified air enters the top air box, the temperature sensor will detect the air temperature and send the detected temperature data to the temperature analysis module. The temperature analysis module will compare the real-time temperature with the threshold humidity of the device. If the real-time humidity is higher than the threshold humidity, the temperature analysis module will send an overheat signal to the controller. If the real-time temperature is lower than the threshold temperature, the temperature analysis module will send an undertemperature signal to the controller. If the real-time temperature is within the normal range, the temperature analysis module will send a normal temperature signal to the controller.

[0024] S7. When the controller receives an overheat signal, it will turn on the cooling coil to cool the air; when the controller receives a low temperature signal, it will turn on the heating plate to heat the air; when the controller receives a normal temperature signal, both the cooling coil and the heating plate will be turned off.

[0025] S8. The internal temperature of the top air box will be adjusted to the normal value. Air at the normal temperature will enter the transformer room, low-voltage room and high-voltage room through the top duct. Then the air will be discharged into the bottom air box through the bottom duct. The air flow will regulate the temperature and humidity in the transformer room, low-voltage room and high-voltage room, and complete the ventilation of the transformer room, low-voltage room and high-voltage room.

[0026] S9. The air discharged from the transformer room, low-pressure room and high-pressure room will flow into the heat pipe on the right side through the air outlet pipe. The air will flow in the heat exchanger and finally be discharged from the heat pipe on the left side.

[0027] S10. The residual heat in the air discharged from the transformer room, low-pressure room and high-pressure room will be used to heat the outside air entering the dehumidifier through the heat exchanger. After the outside air is heated, its relative humidity will decrease, and the power and energy consumption of the dehumidifier will decrease.

[0028] S11. If the controller receives a signal that the humidity is too low, the controller will open the solenoid valves on the two air pipes and one air outlet pipe. The outside air will flow into the humidifier from the air inlet pipe. The controller will turn on the humidifier, and the humidifier will humidify the air to the normal humidity. The humidified air will enter the air box at the top.

[0029] S12. If the controller receives a signal indicating that the humidity is normal, the controller will open the solenoid valves on the left side of the cold pipe, an air outlet pipe, and an air pipe 3. The air with residual heat will be discharged directly. The outside air will only pass through the heat exchanger and eventually flow into the top air box through the air pipe 3 and the air inlet pipe. The air humidity will not be processed.

[0030] Compared with the prior art, the advantages of this invention are:

[0031] This solution uses the waste heat from the air discharged from the transformer room, low-voltage room and high-voltage room to heat the outside air entering the dehumidifier through a heat exchanger. After the outside air is heated, its relative humidity will decrease, the power and energy consumption of the dehumidifier will decrease, thereby effectively reducing the power consumption of the dehumidifier and improving the environmental protection capability of the device.

[0032] When the ambient humidity is normal and the temperature is low, the outside air enters the heat exchanger and exchanges heat with the exhaust air, which raises the air temperature and effectively reduces the energy consumption of the electric heating plate, thus improving the environmental protection capability of the device.

[0033] The condensate from the heat exchanger flows into a water tank for collection through a condensate pipe. A water pump can then pump the condensate into the humidifier's water box through a liquid filling pipe, thus achieving automatic water replenishment. At the same time, the condensate can be reused, improving the device's environmental protection capabilities. Attached Figure Description

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0046] In order to utilize the heat in the air discharged from transformer substation 1, this solution provides Example 1:

[0047] Please see Figures 1-9In this invention: a prefabricated substation with a built-in temperature and humidity linkage heat dissipation system includes a prefabricated substation 1. The prefabricated substation 1 contains a transformer room, a low-voltage room, and a high-voltage room. Air boxes 2 are fixedly connected to the top and bottom of the prefabricated substation 1. Multiple conduits 3 are fixedly connected to opposite sides of the two air boxes 2, and one end of each set of conduits 3 is connected to the transformer room, low-voltage room, and high-voltage room. An installation cabinet 4 is fixedly connected to the left side of the prefabricated substation 1. A humidifier 5, a dehumidifier 6, and a heat exchanger 7 are fixedly connected to the inner wall of the installation cabinet 4. An air inlet pipe 8 is fixedly connected to the left side of the prefabricated substation 1, and a fan 9 and a humidity sensor 10 are installed on the air inlet pipe 8. An air inlet pipe 11 is fixedly connected to the left side of the top air boxes 2, and the air inlet pipe... The left end of 11 extends through and into the interior of the mounting cabinet 4. The left end of the air inlet pipe 11 and the right end of the air inlet pipe 8 are both closed. The left side of the bottom air box 2 is fixedly connected to the air outlet pipe 12, and the left end of the air outlet pipe 12 extends through and into the left side of the mounting cabinet 4. The two cold ports and two hot ports of the heat exchanger 7 are respectively fixedly connected to cold pipes 14 and hot pipes 15. The top ends of the two cold pipes 14 are respectively connected to the bottom of the air inlet pipe 8 and the air inlet of the dehumidifier 6. The bottom end of the right hot pipe 15 is connected to the air outlet pipe 12, and the bottom end of the left hot pipe 15 extends through and into the left side of the mounting cabinet 4. The air outlet of the dehumidifier 6 is fixedly connected to an air pipe 16, and the top end of the air pipe 16 is connected to the air inlet pipe 11. The air inlet and outlet of the humidifier 5 are connected through the air outlet. Each of the two air pipes 17 is fixedly connected to an air inlet pipe 8 and an air inlet pipe 11, respectively. An air pipe 18 connects the right-side cold pipe 14 to the air inlet pipe 11. Solenoid valves 19 are installed on the two cold pipes 14, the two air pipes 17, the one air pipe 16, the one air pipe 18, the right-side hot pipe 15, and the air outlet pipe 12. A temperature control mechanism 20 is installed on the top air box 2. A controller 13 that controls the opening and closing of the humidifier 5, the dehumidifier 6, the fan 9, the humidity sensor 10, and the solenoid valves 19 is fixedly connected to the inner wall of the mounting cabinet 4. The controller 13 integrates a humidity analysis module 21. The input of the humidity analysis module 21 is connected to the signal of the humidity sensor 10, and the output of the humidity analysis module 21 is connected to the controller. 13 Signal Connection; The temperature control mechanism 20 includes a temperature sensor 201, the bottom of which is fixedly connected to the air inlet pipe 11. The probe of the temperature sensor 201 extends through and into the interior of the air inlet pipe 11. The controller 13 integrates a temperature analysis module 204. The output end of the temperature sensor 201 is signal-connected to the temperature analysis module 204. The inner wall of the top air box 2 is fixedly connected to an electric heating plate 202 and a cooling chip 203. The input ends of the electric heating plate 202 and the cooling chip 203 are both signal-connected to the controller 13. The heat absorption surface of the cooling chip 203 is located inside the top air box 2. The heat dissipation surface of the cooling chip 203 extends through and into the back of the top air box 2. The back of the top air box 2 has a fan for cooling the cooling chip 203.

[0048] In this invention, when the operation begins, the controller 13 controls the fan 9 to start, and the fan 9 draws outside air into the air intake pipe 8. When the air flows, the humidity sensor 10 detects the humidity of the air and sends the detected data to the humidity analysis module 21. The humidity analysis module 21 compares the real-time humidity with the set threshold humidity. When the real-time humidity is higher than the threshold humidity, the humidity analysis module 21 sends an over-humidity signal to the controller 13. When the real-time temperature is lower than the threshold humidity, the humidity analysis module 21 sends an under-humidity signal to the controller 13. When the real-time temperature is within the normal range, the humidity analysis module 21 sends a normal humidity signal to the controller 13.

[0049] After receiving an overhumidity signal, the controller 13 will open the solenoid valves 19 on the two cold pipes 14, the right heat pipe 15, and the air pipe 16. Air will flow from the air inlet pipe 8 into the cold pipe 14 on the left. The air will flow in the heat exchanger 7 and finally flow from the cold pipe 14 on the right into the dehumidifier 6. The controller 13 will turn on the dehumidifier 6 and the dehumidifier 6 will dehumidify the air. The dehumidified air will enter the air inlet pipe 11 through the air pipe 16 and finally enter the top air box 2.

[0050] After the dehumidified air enters the top air box 2, the temperature sensor 201 detects the air temperature and sends the detected temperature data to the temperature analysis module 204. The temperature analysis module 204 compares the real-time temperature with the threshold humidity of the device. If the real-time humidity is higher than the threshold humidity, the temperature analysis module 204 sends an overheat signal to the controller 13. If the real-time temperature is lower than the threshold temperature, the temperature analysis module 204 sends an undertemperature signal to the controller 13. If the real-time temperature is within the normal range, the temperature analysis module 204 sends a normal temperature signal to the controller 13.

[0051] When the controller 13 receives an overheating signal, the controller 13 will turn on the cooling chip 203 to cool the air temperature.

[0052] When the controller 13 receives a signal that the temperature is too low, the controller 13 will turn on the heating plate 202 to heat the temperature.

[0053] When the controller 13 receives a normal temperature reading, both the cooling chip 203 and the heating plate 202 are in the off state.

[0054] The internal temperature of the top air box 2 will be adjusted to a normal value. Air at a normal temperature will enter the transformer room, low-voltage room and high-voltage room through the top duct 3. Then the air will be discharged into the bottom air box 2 through the bottom duct 3. The air flow will regulate the temperature and humidity in the transformer room, low-voltage room and high-voltage room, thus completing the ventilation of the transformer room, low-voltage room and high-voltage room.

[0055] The air discharged from the transformer room, low-pressure room and high-pressure room will flow from the air outlet duct 12 into the heat pipe 15 on the right. The air will flow in the heat exchanger 7 and finally be discharged from the heat pipe 15 on the left.

[0056] The residual heat from the air discharged from the transformer room, low-pressure room, and high-pressure room will be used by the heat exchanger 7 to heat the outside air entering the dehumidifier 6. After the outside air is heated, its relative humidity will decrease, the power and energy consumption of the dehumidifier 6 will decrease, thereby effectively reducing the electricity consumption of the dehumidifier 6 and improving the environmental protection capability of the device.

[0057] If the controller 13 receives a signal that the humidity is too low, the controller 13 will open the solenoid valves 19 on the two air pipes 17 and the air outlet pipe 12. At this time, the outside air will flow into the humidifier 5 from the air inlet pipe 8. The controller 13 will turn on the humidifier 5, and the humidifier 5 will humidify the air to the normal humidity. The humidified air will enter the air box 2 at the top.

[0058] If the controller 13 receives a signal that the humidity is normal, the controller 13 will open the solenoid valve 19 on the left side cold pipe 14, an air outlet pipe 12 and an air pipe 18. At this time, the air with residual heat is directly discharged, and the outside air only passes through the heat exchanger 7 and finally flows into the top air box 2 through the air pipe 18 and the air inlet pipe 11 without processing the air humidity.

[0059] In winter, the outside air temperature is low, and the electric heating plate 202 needs to operate at high power continuously to heat the outside air, which consumes a lot of electrical energy. In order to reduce energy consumption in winter, this solution provides an embodiment two:

[0060] When the outside air humidity is normal and the temperature is low in winter, the worker opens the solenoid valves 19 on the left cold pipe 14, air pipe 3 18 and right heat pipe 15 through the controller 13. At this time, the outside air enters the heat exchanger 7 and exchanges heat with the exhaust air, and the air temperature will rise. After the air temperature rises, it will enter the air box 2 at the top through air pipe 3 18. At this time, the air temperature rises, thereby effectively reducing the energy consumption of the electric heating plate 202 and improving the environmental protection capability of the device.

[0061] Please see Figures 1-7The left end of the air intake pipe 8 is fitted with a cylinder 22 that is threadedly connected to it, and a filter plate 23 is fixedly connected to the inner wall of the cylinder 22.

[0062] In this invention, the arrangement of the cylinder 22 and the filter plate 23 can filter the air, preventing dust in the air from contaminating the internal components of the transformer substation 1 and improving the practicality of the device.

[0063] Please see Figure 4 and 5 Among them: a pressure sensor 24 is fixedly connected to the inner wall of the air intake pipe 8, and an alarm 25 is fixedly connected to the inner wall of the mounting cabinet 4. The output end of the pressure sensor 24 is connected to the alarm 25.

[0064] In this invention, the pressure sensor 24 can detect the pressure in the air intake pipe 8 in real time. When the filter plate 23 is blocked by dust particles, the air intake is obstructed and the pressure in the air intake pipe 8 will decrease. When the filter plate 23 is severely blocked and needs cleaning and maintenance, the value detected by the pressure sensor 24 will be lower than the threshold. The pressure sensor 24 will send a signal to the alarm 25, and the alarm 25 will sound an alarm to remind the worker to clean the filter plate 23 in time.

[0065] Please see Figure 4 The transformer substation 1 has three cavities 26 inside. The inner walls of the three cavities 26 are all connected to the top conduit 3. The inner walls of the three cavities 26 are all provided with evenly distributed air vents 27, which are connected to the transformer room, the low-voltage room and the high-voltage room respectively.

[0066] In this invention, after the temperature and humidity of the air are adjusted, it enters the cavity 26 through the conduit 3. The air is then evenly sprayed from the evenly distributed air outlets 27 onto the components installed inside the transformer room, low-voltage room and high-voltage room, thereby improving the uniformity of heat dissipation for the components and improving the practicality of the device.

[0067] When heat exchanger 7 exchanges heat with the incoming and outgoing air, it will generate a certain amount of condensate. Directly discharging the condensate would be a waste of resources. In order to utilize the condensate, this solution provides Embodiment 3:

[0068] Please see Figure 4 , 67, wherein: a water tank 28 is fixedly connected to the inner wall of the installation cabinet 4, the condensate pipe of the heat exchanger 7 is connected to the water tank 28, a horizontal pipe 29 is fixedly connected to the left side of the water tank 28, the left end of the horizontal pipe 29 passes through and extends to the left side of the installation cabinet 4, a valve is installed on the horizontal pipe 29, a liquid filling pipe 30 is fixedly connected to the top of the water tank 28 and communicates with it, the top end of the liquid filling pipe 30 is fixedly connected to the liquid filling port of the humidifier 5, a water pump 31 is installed on the liquid filling pipe 30, the output end of the humidifier 5 is signal connected to the controller 13, and the output end of the controller 13 is signal connected to the water pump 31.

[0069] In this invention, during the heat exchange process, the condensate from the heat exchanger 7 flows into the water tank 28 through the condensate pipe for collection. The water pump 31 can pump the condensate into the water box of the humidifier 5 through the liquid filling pipe 30, thereby achieving the effect of automatic water replenishment. At the same time, the condensate can be reused, improving the environmental protection capability of the device.

[0070] This invention also provides a control method for a prefabricated substation with a built-in temperature and humidity-linked heat dissipation system, applicable to the aforementioned prefabricated substation with a built-in temperature and humidity-linked heat dissipation system, comprising the following steps:

[0071] S1. When the work starts, the controller 13 controls the fan 9 to start. The fan 9 will draw outside air into the air intake pipe 8. When the air flows, the humidity sensor 10 will detect the humidity of the air and send the detected data to the humidity analysis module 21.

[0072] S2. The humidity analysis module 21 compares the real-time humidity with the set threshold humidity. If the real-time humidity is higher than the threshold humidity, the humidity analysis module 21 will send an over-humidity signal to the controller 13. If the real-time temperature is lower than the threshold humidity, the humidity analysis module 21 will send an under-humidity signal to the controller 13. If the real-time temperature is within the normal range, the humidity analysis module 21 will send a normal humidity signal to the controller 13.

[0073] S3. After receiving the over-humidity signal, the controller 13 will open the solenoid valves 19 on the two cold pipes 14, the right heat pipe 15, and the air pipe 16.

[0074] S4. Air will flow from the intake pipe 8 into the left-side cold pipe 14, and the air will flow in the heat exchanger 7, eventually flowing from the right-side cold pipe 14 into the dehumidifier 6.

[0075] S5. When air enters the dehumidifier 6, the controller 13 will turn on the dehumidifier 6. The dehumidifier 6 will dehumidify the air. The dehumidified air will enter the air inlet pipe 11 through the air pipe 16. Finally, the dehumidified air will enter the top air box 2.

[0076] S6. After the dehumidified air enters the top air box 2, the temperature sensor 201 will detect the air temperature and send the detected temperature data to the temperature analysis module 204. The temperature analysis module 204 will compare the real-time temperature with the threshold humidity of the device. If the real-time humidity is higher than the threshold humidity, the temperature analysis module 204 will send an overheat signal to the controller 13. If the real-time temperature is lower than the threshold temperature, the temperature analysis module 204 will send an undertemperature signal to the controller 13. If the real-time temperature is within the normal range, the temperature analysis module 204 will send a normal temperature signal to the controller 13.

[0077] S7. When the controller 13 receives an overheat signal, the controller 13 will turn on the cooling chip 203 to cool the air temperature; when the controller 13 receives a low temperature signal, the controller 13 will turn on the heating plate 202 to heat the temperature; when the controller 13 receives a normal temperature signal, both the cooling chip 203 and the heating plate 202 will be in the off state.

[0078] S8. The internal temperature of the top air box 2 will be adjusted to the normal value. Air at the normal temperature will enter the transformer room, low-voltage room and high-voltage room from the top duct 3. Then the air will be discharged into the bottom air box 2 from the bottom duct 3. The air flow will regulate the temperature and humidity in the transformer room, low-voltage room and high-voltage room, and complete the ventilation of the transformer room, low-voltage room and high-voltage room.

[0079] S9. The air discharged from the transformer room, low-pressure room and high-pressure room will flow from the air outlet duct 12 into the heat pipe 15 on the right. The air will flow in the heat exchanger 7 and finally be discharged from the heat pipe 15 on the left.

[0080] S10. The residual heat in the air discharged from the transformer room, low-pressure room and high-pressure room will be used to heat the external air entering the dehumidifier 6 through the heat exchanger 7. After the external air is heated, its relative humidity will decrease, and the power and energy consumption of the dehumidifier 6 will decrease.

[0081] S11. If the controller 13 receives a signal that the humidity is too low, the controller 13 will open the solenoid valves 19 on the two air pipes 17 and the air outlet pipe 12. The outside air will flow into the humidifier 5 from the air inlet pipe 8. The controller 13 will turn on the humidifier 5. The humidifier 5 will humidify the air and humidify the outside air to the normal humidity. The humidified air will enter the air box 2 at the top.

[0082] S12. If the controller 13 receives a signal that the humidity is normal, the controller 13 will open the solenoid valves 19 on the left heat pipe 15, air pipe 16, an air outlet pipe 12 and an air pipe 3 18. The air with residual heat will be discharged directly. The outside air will only pass through the heat exchanger 7 and finally flow into the top air box 2 through the air pipe 3 18 and the air inlet pipe 11. The air humidity will not be processed.

When the work starts, the controller (13) controls the fan (9) to start. The fan (9) will draw outside air into the air intake pipe (8). When the air flows, the humidity sensor (10) will detect the humidity of the air and send the detected data to the humidity analysis module (21). S2. The humidity analysis module (21) compares the real-time humidity with the set threshold humidity.
