[0091] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0092] The following description, with reference to the accompanying drawings, describes a cold source system and control method, electronic device, and storage medium according to embodiments of the present disclosure.

[0093] Please see Figure 1 , Figure 1 A schematic diagram of a cold source system provided in an embodiment of this application includes: an air-cooled heat exchanger, a first pipeline, a second pipeline, and a spray pipeline;

[0094] The inlet of the air-cooled heat exchanger is connected to the first end of the first pipeline;

[0095] The outlet of the air-cooled heat exchanger is connected to the first end of the second pipeline;

[0096] The wet curtain of the air-cooled heat exchanger is connected to the first end of the spray pipe.

[0097] The first pipeline is the inlet water pipeline of the air-cooled heat exchanger, and the second pipeline is the second pipeline of the air-cooled heat exchanger. After the liquid in the first pipeline flows through the air-cooled heat exchanger and undergoes heat exchange, it returns to the cooling equipment through the second pipeline. The spray pipeline is connected to the wet curtain in the air-cooled heat exchanger. The wet curtain is used to reduce the temperature of the natural wind to improve the heat exchange efficiency of the air-cooled heat exchanger.

[0098] The cold source system disclosed herein mainly includes: an air-cooled heat exchanger, a first pipeline, a second pipeline, and a spray pipeline; the inlet of the air-cooled heat exchanger is connected to the first end of the first pipeline; the outlet of the air-cooled heat exchanger is connected to the first end of the second pipeline; and the wet curtain of the air-cooled heat exchanger is connected to the first end of the spray pipeline. Compared with related technologies, the embodiments of this application achieve resource sharing between air cooling and liquid cooling, simplify the system architecture, and achieve high integration. Furthermore, by simplifying and optimizing the control strategy, not only is the system design more concise, but the stability and energy efficiency of the system are also improved, ensuring the reliability and energy-saving performance of the system during operation.

[0099] In one possible implementation of this disclosure, the first pipeline includes a first electric heating belt, a degassing tank, a first pressure sensor, a circulating pump, a second pressure sensor, an electric butterfly valve, and a first temperature sensor.

[0100] The first end of the circulating pump is connected to the inlet of the air-cooled heat exchanger via the second pressure sensor, the electric butterfly valve and the first temperature sensor.

[0101] The second end of the circulating pump is connected to the first end of the degassing tank via the first pressure sensor; the second end of the degassing tank is connected to the water inlet pipe via the first electric heating element.

[0102] The first end of the circulating pump is equipped with a first manual butterfly valve and a check valve, and the second end of the circulating pump is equipped with a second manual butterfly valve.

[0103] Before the circulating pump delivers cooling water to the air-cooled heat exchanger, it monitors water flow and temperature using a series of monitoring and control components, including pressure sensors, electric butterfly valves, and temperature sensors.

[0104] The outlet of the circulation pump is connected to a degassing tank to remove gas from the system, while a pressure sensor monitors the water pressure. An electric heating element is used to maintain the water temperature when necessary, preventing it from becoming too cold. A first manual butterfly valve, a second manual butterfly valve, and a check valve provide additional control and safety measures, allowing for manual adjustment of the water flow or prevention of backflow when needed.

[0105] The return water passes through the degassing tank, inlet pressure gauge, and first pressure sensor, then through the circulation pump, inlet manual butterfly valve, check valve, outlet manual butterfly valve, outlet pressure gauge, second pressure sensor, and electric butterfly valve before entering the air-cooled finned heat exchanger for heat exchange via the first temperature sensor.

[0106] In one possible implementation of this disclosure, the second pipeline includes a second temperature sensor, a third temperature sensor, a third pressure sensor, a filter, a fourth pressure sensor, a fourth temperature sensor, and a second electric heating element.

[0107] The first end of the filter is connected to the outlet of the air-cooled heat exchanger via the third pressure sensor, the third temperature sensor, and the second temperature sensor.

[0108] The second end of the filter is connected to the second pipeline via the fourth pressure sensor, the fourth temperature sensor, and the second electric heating band.

[0109] After heat exchange, the filtered water passes through the heat exchanger outlet valve, the second temperature sensor, the third temperature sensor, the third pressure sensor, the valve before the filter, the filter, the valve after the filter, the fourth pressure sensor, the flow sensor, and the fourth temperature sensor before entering the second pipeline.

[0110] Multiple sensors (third pressure sensor, third temperature sensor, second temperature sensor, fourth pressure sensor, and fourth temperature sensor) are installed in the second pipeline. The system can monitor the changes in water quality, temperature, and pressure after heat exchange in real time to ensure that the system operates in the best condition.

[0111] The filter removes impurities from the water. By filtering immediately after the water exits the heat exchanger, it maintains water quality, prevents scaling and corrosion within the system, and extends the equipment's lifespan. A second electric heating element is used to adjust the outlet water temperature when necessary.

[0112] By precisely controlling the temperature and flow rate of the cooling water, the system can use energy more efficiently, reduce waste, and lower its environmental impact.

[0113] In some embodiments, the second pipeline and the water inlet pipeline may be connected to cooling equipment, such as air conditioners, liquid cooling cabinets, etc. However, this application does not limit this specific embodiment.

[0114] The design, which connects the first and second pipelines to the air-cooled heat exchanger, achieves a complementary advantage of liquid cooling and air cooling. The liquid can efficiently remove the heat generated by the equipment and dissipate it into the air through the air-cooled heat exchanger, greatly improving heat dissipation efficiency, effectively reducing the operating temperature of the equipment, improving its performance and reliability, and extending its service life.

[0115] In one possible implementation of this disclosure, the system further includes: a first bypass valve and a second bypass valve;

[0116] The first end of the first bypass valve is disposed between the electric butterfly valve and the second pressure sensor; the second end of the first bypass valve is disposed between the second temperature sensor and the third temperature sensor.

[0117] The first end of the second bypass valve is located between the circulating pump and the first pressure sensor; the second end of the second bypass valve is located between the third temperature sensor and the third pressure sensor.

[0118] The primary function of the first bypass valve is to bypass the supply and return water, ensuring that the outlet water temperature is not lower than a predetermined value. When the outlet water temperature is detected to be lower than the set threshold, the first bypass valve can be opened, allowing some water that has not been cooled by the air-cooled heat exchanger to flow directly into the return water pipeline, thereby increasing the outlet water temperature. In some embodiments, the first bypass valve can be used to balance the water flow in the system during system startup or shutdown, reducing water hammer effects and protecting the system from damage.

[0119] The second bypass valve mainly controls the supply and return water pressure difference of the system to not exceed the limit, and plays the role of bypassing the system pressure; when the system needs to adjust the water flow path or pressure, the second bypass valve can provide a means of adjustment, such as maintaining a stable pressure when the system load changes.

[0120] In one possible implementation of this disclosure, the spray pipeline includes a water collection tray, a drain solenoid valve, a water replenishment solenoid valve, and a spray water replenishment pump;

[0121] The first end of the water collection tray is connected to the wet curtain of the air-cooled heat exchanger via the water replenishment solenoid valve, the spray water replenishment pump, and the wet curtain of the air-cooled heat exchanger.

[0122] The second end of the water collection tray is connected to the spray inlet;

[0123] The third end of the water collection tray is connected to the drain outlet via the drain solenoid valve.

[0124] The water collection tray is the main source of water for the spray system. When the wet curtain is supplied with water, the water replenishment solenoid valve will open, allowing the spray water replenishment pump to draw water from the water collection tray to replenish the wet curtain, so as to enhance the heat exchange effect or for cooling. The third end of the water collection tray is connected to the drain outlet through the drain solenoid valve, which is used to drain the water in the water collection tray when the system is shut down or when drainage is required.

[0125] In one possible implementation of this disclosure, the system further includes a water supply pipeline, which includes a water storage tank, a first manual valve, a water supply pump, and a second manual valve.

[0126] The first end of the water storage tank is connected to the first end of the water replenishment pump via the first hand valve;

[0127] The second end of the water replenishment pump is connected to the third end of the degassing tank via the second hand valve;

[0128] A water supply hose is provided between the water supply pump and the first hand valve.

[0129] Please see Figure 2 , Figure 2 This is a schematic diagram of another cold source system provided in an embodiment of this application; as shown. Figure 2 As shown, the first end of the water storage tank is connected to the first end of the water supply pump through a first-hand valve. The operator can manually control the first-hand valve to turn the water supply of the water supply pump on or off, thereby controlling the water supply process.

[0130] When the liquid level in the storage tank is below the limit, the tank is replenished directly using the water replenishment pump until the tank reaches the high liquid level, at which point the pump stops. Normal water replenishment is performed using the water replenishment pump. When the first pressure detection value is ≤0.08MPa, the system is replenished by opening the manual valve. When the system pressure exceeds 0.11MPa, the water replenishment pump is shut off.

[0131] In one possible implementation of this disclosure, the water supply pipeline further includes a solenoid valve;

[0132] The water storage tank is connected to the fourth end of the degassing tank via the solenoid valve.

[0133] Please continue reading. Figure 1 During the initial water replenishment, the first pressure value of the first pressure sensor is determined. When the first pressure value is lower than 0.1 MPa, the first manual valve is closed, and the water replenishment pump is turned on to replenish the system. When the water tank reaches a high level, the water replenishment pump is turned off. When the first pressure value is ≤0.08 MPa, the system is replenished, and the first manual valve is opened. When the first pressure value exceeds 0.11 MPa, the water replenishment pump is turned off. Only when the liquid level in the liquid tank is low will an alarm be issued, the first manual valve be closed, and the water replenishment pump be manually turned on through the water replenishment hose to replenish the system until a high liquid level in the liquid tank is detected, at which point the pump will automatically stop.

[0134] In one possible implementation of this disclosure, the system further includes a first liquid-cooled cabinet, a second liquid-cooled cabinet, and an air conditioner, wherein the air conditioner includes a condenser;

[0135] The water outlet of the first liquid cooling cabinet, the water outlet of the second liquid cooling cabinet, and the water outlet of the condenser are connected in parallel to the second end of the first pipeline;

[0136] The water inlet of the first liquid cooling cabinet, the water inlet of the second liquid cooling cabinet, and the water inlet of the condenser are connected in parallel to the second end of the second pipeline.

[0137] Please see Figure 3 , Figure 3 This is a schematic diagram of another cold source system provided in an embodiment of this application, such as... Figure 3 As shown, a parallel connection is used so that the cooling water in the second pipeline can be distributed to multiple liquid-cooled cabinets and condensers simultaneously. The cooling water from different liquid-cooled cabinets and condensers flows back to the first pipeline. In the event of a failure in one liquid-cooled cabinet or condenser, other components can still operate normally, reducing the impact of a single point of failure on the entire system.

[0138] The air-liquid direct drive unit can be directly connected to the liquid-cooled cabinet to provide liquid cooling for the liquid-cooled server; another line connects to the condenser of the air-cooled in-row air conditioner to provide air cooling for the server through compression refrigeration.

[0139] Please see Figure 4 , Figure 4 This is a schematic diagram of an air-cooled air conditioner provided in an embodiment of this application. The air-cooled air conditioner mainly consists of a fan, an evaporator, an expansion valve, and a plate heat exchanger condenser. The condenser heats the coolant after heat exchange through a first pipeline.

[0140] In one possible implementation of this disclosure, the system further includes: a cooling distribution unit;

[0141] The first outlet of the cooling distribution unit and the outlet of the condenser are connected in parallel to the first end of the first pipeline.

[0142] The first water inlet of the cooling distribution unit and the water inlet of the condenser are connected in parallel to the second end of the second pipeline;

[0143] The water outlets of the first liquid cooling cabinet and the second liquid cooling cabinet are connected in parallel to the second water inlet of the cooling distribution unit;

[0144] The water inlet of the first liquid cooling cabinet and the water inlet of the second liquid cooling cabinet are connected in parallel to the second water outlet of the cooling distribution unit.

[0145] Please see Figure 5 , Figure 5 This is a schematic diagram of another cold source system provided in an embodiment of this application. In this connection method, cooling water is distributed to the first and second liquid-cooled cabinets through a Cooling Distribution Unit (CDU). The cooling water distribution ratio can be determined according to the actual thermal management requirements of the first and second liquid-cooled cabinets to ensure that the coolant is effectively transferred to the areas requiring heat dissipation. The CDU is equipped with a water pump and a heat exchanger. The secondary side piping and the liquid cooling load of the server are carried through the CDU heat exchanger. Another path connects to the condenser of the air-cooled in-row air conditioner, providing air cooling to the server through compression refrigeration.

[0146] The integrated spray water tank of the heat exchanger comes with a drain solenoid valve. The valve's opening and closing is controlled by the ambient temperature T0. An alarm is triggered when T0 is below a first preset value (e.g., 10℃), and the drain solenoid valve opens when T0 is below a second preset threshold (e.g., 5℃), draining the water from the water pan. This triggers an anti-freeze alarm, reminding maintenance personnel to open the drain in the spray water pump to prevent it from freezing.

[0147] Figure 6 This is a schematic flowchart illustrating a cold source control method provided in an embodiment of this disclosure. Figure 6 As shown, the method is applied to the aforementioned cold source system, and the method includes the following steps:

[0148] Step 101: Obtain the first outlet water temperature detected by the second temperature sensor.

[0149] The second temperature sensor is installed near the water outlet to monitor the water temperature in real time, i.e., the first water temperature.

[0150] Step 102: Determine the temperature range that the first outlet water temperature meets based on the preset temperature level threshold.

[0151] To precisely regulate water temperature to meet diverse needs, a temperature range satisfying the first outlet water temperature is determined based on preset temperature level thresholds. In some feasible methods, temperature level thresholds can be set based on the highest and lowest temperatures. If the first outlet water temperature is below the low-temperature threshold, it is determined to be in the low-temperature range; if it is between the low-temperature and medium-temperature thresholds, it belongs to the medium-temperature range; and if it is above the high-temperature threshold, it naturally falls into the high-temperature range. Based on the range it falls into, the system intelligently adjusts to ensure that the water temperature is always within a suitable range.

[0152] Step 103: Control the fan speed of the air-cooled heat exchanger according to the temperature range satisfied by the first outlet water temperature, so that the first outlet water temperature meets the target outlet water temperature.

[0153] After determining the range of the first outlet water temperature, the fan speed of the air-cooled heat exchanger is precisely controlled according to this range. If the first outlet water temperature is in the low-temperature range and lower than the target outlet water temperature, the system will reduce the fan speed of the air-cooled heat exchanger to slow down the rate of water temperature drop. If necessary, other operations will be taken to promote the water temperature to rise and approach the target outlet water temperature.

[0154] When the initial outlet water temperature is in the high-temperature range and higher than the target outlet water temperature, the system increases the fan speed to enhance heat dissipation and prevent the water temperature from becoming too high, allowing the water temperature to gradually approach the target outlet water temperature. If it is in the medium-temperature range and close to the target outlet water temperature, the system will maintain the current fan speed to stabilize the water temperature near the target value.

[0155] By dynamically adjusting the fan speed of the air-cooled heat exchanger within the temperature range satisfied by the first outlet water temperature, the system can continuously and stably ensure that the first outlet water temperature meets the target outlet water temperature, ensuring a stable and suitable water temperature under various operating conditions, such as ensuring stable equipment operation in industrial cooling systems or providing users with a comfortable water temperature in domestic hot water supply systems.

[0156] In some embodiments, the preset temperature level threshold includes a first temperature threshold and a second temperature threshold, wherein the second temperature threshold is the target outlet water temperature; the step of controlling the airflow speed of the air-cooled heat exchanger according to the temperature range satisfied by the first outlet water temperature, so that the first outlet water temperature satisfies the target outlet water temperature, includes:

[0157] When the first outlet water temperature is greater than the second temperature threshold, the fan speed of the air-cooled heat exchanger is set to the maximum speed, and the spray pipeline is controlled to supply water to the wet curtain.

[0158] When the first outlet water temperature exceeds the second temperature threshold, it indicates that the current water temperature is too high. To quickly lower the water temperature, the fan speed of the air-cooled heat exchanger is set to its maximum speed to maximize airflow and enhance heat dissipation. Simultaneously, to further enhance the cooling effect, the spray pipes are opened to supply water to the evaporative cooling pads. The evaporative cooling pads absorb a large amount of heat during water evaporation; combined with the powerful ventilation from the fan, this significantly accelerates heat dissipation, causing the water temperature to drop rapidly and meet the target outlet water temperature requirement.

[0159] When the first outlet water temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold, the fan speed of the air-cooled heat exchanger is controlled so that the first outlet water temperature meets the target outlet water temperature.

[0160] In some embodiments, the minimum water temperature can be set as a first temperature threshold and the target water temperature can be set as a second temperature threshold. When the first outlet water temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold, it indicates that the water temperature meets the minimum temperature requirement. Based on the difference between the current first outlet water temperature and the target outlet water temperature, the fan speed is dynamically adjusted to gradually reduce the difference between the two, so that the first outlet water temperature can stably meet the target outlet water temperature, ensuring that the system always operates in a stable and efficient state.

[0161] If the first outlet water temperature is lower than the first temperature threshold, the fan speed of the air-cooled heat exchanger is set to zero.

[0162] When the first outlet water temperature is lower than the first temperature threshold, the water temperature does not meet the minimum temperature requirement. The fan speed of the air-cooled heat exchanger is set to zero, the fan stops running, and heat dissipation is reduced.

[0163] By differentiating the fan speed and spray piping of the air-cooled heat exchanger based on the relationship between the first outlet water temperature and different temperature thresholds, precise water temperature control can be achieved. This not only allows for rapid cooling when the water temperature is too high, preventing equipment damage and ensuring stable system operation, but also enables flexible adjustment of the fan speed when the water temperature is moderate, maintaining a constant water temperature, improving energy efficiency, and reducing unnecessary energy consumption. Furthermore, it stops the fan when the water temperature is too low, preventing excessive cooling and protecting the overall performance of the equipment and system.

[0164] In some embodiments, when the first outlet water temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold, after controlling the fan speed of the air-cooled heat exchanger to ensure that the first outlet water temperature meets the target outlet water temperature, the method further includes:

[0165] Obtain the second outlet water temperature detected by the third temperature sensor;

[0166] When the fan speed of the air-cooled heat exchanger is determined to be the lowest speed, and the duration for which the second outlet water temperature is less than the first temperature threshold is greater than or equal to a preset duration threshold, the first bypass valve is controlled to open, and the opening degree of the first bypass valve is controlled so that the second outlet water temperature is greater than or equal to the first temperature threshold.

[0167] When the central control unit receives information indicating that the fan speed of the air-cooled heat exchanger is at its lowest speed and the second outlet water temperature remains below the first temperature threshold for a preset duration, it indicates that the water temperature is too low and has failed to rise to a suitable range on its own within a certain period of time. This triggers a control command to the first bypass valve, controlling its opening. Based on the difference between the current second outlet water temperature and the first temperature threshold, and using a PID control algorithm, the opening of the first bypass valve is dynamically adjusted to allow the first and second pipelines to connect directly without passing through the air-cooled radiator. This allows the second outlet water temperature to gradually rise until it is greater than or equal to the first temperature threshold, restoring it to a suitable temperature range.

[0168] When the first bypass valve reaches its maximum opening and the second outlet water temperature is less than the first temperature threshold, the pipeline electric heating belt is turned on to perform heating.

[0169] If, after fully adjusting the first bypass valve to its maximum opening, the second outlet water temperature remains below the first temperature threshold, this indicates that simply changing the water flow path is insufficient to effectively raise the water temperature. In this extreme case, the pipeline electric heating element is activated. The heating element is evenly wound around the outer walls of the first and second pipelines. Its internal resistance wire rapidly generates heat upon energization and transfers this heat to the water within the pipelines via thermal conduction. In some embodiments, real-time monitoring of the second outlet water temperature precisely controls the heating power of the electric heating element, ensuring a steady rise in water temperature, ultimately reaching and maintaining the first temperature threshold or higher, thus guaranteeing the normal and stable operation of the entire system.

[0170] By intelligently adjusting the opening of the first bypass valve, the system optimizes the water flow path to regulate the water temperature. When the bypass valve reaches its limit, the pipeline electric heater intervenes to ensure that the water temperature is always maintained within the suitable operating range. This control scheme comprehensively enhances the system's temperature management capabilities, playing a crucial role in ensuring normal equipment operation, saving energy, and improving overall system performance, providing a reliable and efficient temperature control solution.

[0171] Optionally, after controlling the fan speed of the air-cooled heat exchanger according to the temperature range satisfied by the first outlet water temperature, the method further includes:

[0172] The difference between the first pressure value detected by the first pressure sensor and the second pressure value detected by the second pressure sensor is determined, and the frequency of the circulating pump is controlled according to the difference to eliminate the pressure difference between the first pressure value and the second pressure value.

[0173] When there is a difference between the first pressure value and the second pressure value, it indicates a pressure imbalance in the circulation system. Based on the PID control algorithm, the frequency of the circulation pump is adjusted according to the magnitude and trend of the pressure difference.

[0174] If the pressure difference is positive, it indicates that the first pressure value is higher than the second pressure value. The system will reduce the frequency of the circulation pump and decrease the fluid flow rate, thereby lowering the first pressure value. Conversely, if the pressure difference is negative, the system will increase the frequency of the circulation pump and increase the fluid flow rate to raise the second pressure value. Through this dynamic adjustment, the pressure difference between the two pressure values ​​is gradually eliminated, ensuring stable pressure in the circulation system, guaranteeing the normal operation of all equipment in the system, and avoiding equipment damage or efficiency reduction caused by uneven pressure.

[0175] When the frequency of the circulating pump is at its lowest frequency, the second bypass valve is opened, and the opening degree of the second bypass valve is controlled to eliminate the pressure difference between the first pressure value and the second pressure value; or,

[0176] When the circulation pump frequency has been reduced to its minimum, but the pressure difference between the first and second pressure values ​​has not been eliminated, adjusting the circulation pump frequency cannot resolve the current pressure imbalance. In this case, the second bypass valve is opened, and its opening degree is dynamically adjusted based on the real-time pressure difference and system operating conditions. By changing the flow rate and velocity of the fluid in the bypass pipeline, the overall pressure distribution of the system is altered.

[0177] The frequency of the circulation pump is controlled by determining the temperature difference between the second temperature threshold and the third outlet water temperature detected by the fourth temperature sensor.

[0178] When the temperature difference is positive, meaning the third outlet water temperature is lower than the second temperature threshold, it indicates that the system requires more heat transfer. In this case, the system will increase the frequency of the circulation pump. This increases the fluid circulation speed, allowing more heat to be carried to the required area, thereby raising the third outlet water temperature. Conversely, if the temperature difference is negative, meaning the third outlet water temperature is higher than the second temperature threshold, the system will decrease the frequency of the circulation pump, reducing heat transfer.

[0179] Precise monitoring of the pressure values ​​from the first and second pressure sensors, and adjusting the circulation pump frequency based on the pressure difference, enables rapid and effective pressure balancing within the system. This ensures stable operation of all equipment under stable pressure, preventing equipment damage and leaks caused by uneven pressure, and extending equipment lifespan. When a pressure difference still exists even at the lowest circulation pump frequency, opening and adjusting the second bypass valve ensures pressure balance, enhancing the system's ability to handle complex pressure conditions and improving operational stability and reliability. Controlling the circulation pump frequency based on the temperature difference between the second temperature threshold and the third outlet water temperature achieves precise temperature control, ensuring the water temperature remains within a suitable range. This not only optimizes the system's heat exchange efficiency but also provides reliable protection for processes or equipment reliant on stable water temperatures.

[0180] Optionally, after controlling the fan speed of the air-cooled heat exchanger according to the temperature range satisfied by the first outlet water temperature, the method further includes:

[0181] When the ambient temperature is below the third temperature threshold, control the shut-off of the spray pipe to supply water to the wet curtain;

[0182] When the ambient temperature sensor detects that the ambient temperature is lower than the preset third temperature threshold, the water supply valve of the wet curtain spray system will shut off to prevent unnecessary energy consumption and ensure that no water flows to the wet curtain. This avoids unnecessary spraying operations in low-temperature environments and ensures the rational use of energy.

[0183] In some embodiments, the third temperature threshold is an empirical value, which can be set according to actual needs, such as 30 degrees or 33 degrees. However, this application does not limit this aspect in the embodiments.

[0184] When the ambient temperature is higher than the third temperature threshold, the spray pipeline is controlled to supply water to the wet curtain.

[0185] When the ambient temperature sensor detects that the ambient temperature is higher than the third temperature threshold, the system needs to use the evaporation of water from the wet curtain to lower the ambient air temperature in order to meet the system's requirements for ambient temperature regulation.
