[0091] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0092] The cold source system and control method, electronic device and storage medium according to the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0093] See also Figure 1 , Figure 1 A schematic diagram of a cold source system provided in an embodiment of the present application, comprising: an air-cooled heat exchanger, a first pipeline, a second pipeline, and a spray pipeline;

[0094] The water inlet of the air-cooled heat exchanger is in communication with the first end of the first pipe;

[0095] The water outlet of the air-cooled heat exchanger is in communication with the first end of the second pipe;

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

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

[0098] The cold source system provided by the present disclosure mainly includes the following technical solutions: an air-cooled heat exchanger, a first pipeline, a second pipeline, and a spray pipeline; the water inlet of the air-cooled heat exchanger is connected to the first end of the first pipeline; the water outlet of the air-cooled heat exchanger is connected to the first end of the second pipeline; the wet curtain of the air-cooled heat exchanger is connected to the first end of the spray pipeline. Compared with the related art, the embodiment of the present application realizes the resource sharing of air cooling and liquid cooling, simplifies the system architecture, and achieves high integration. In addition, by streamlining and optimizing the control strategy, not only the system design is made simpler, but also the stability and energy-saving efficiency of the system are improved, ensuring the reliability and energy-saving performance of the system during operation.

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

[0100] The first end of the circulation pump is connected to the water 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 circulation 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 belt;

[0102] Wherein, a first manual butterfly valve and a check valve are arranged at the first end of the circulation pump, and a second manual butterfly valve is arranged at the second end of the circulation pump.

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

[0104] The outlet of the circulation pump is connected to the degassing tank to remove gas from the system, while the water pressure is monitored by a pressure sensor. The electric heating belt is used to maintain the water temperature when necessary to prevent the water temperature from being too low. The first manual butterfly valve, the second manual butterfly valve and the check valve provide additional control and safety measures to manually adjust the water flow or prevent water backflow when necessary.

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

[0106] In one possible implementation of the embodiment of the present disclosure, the water outlet pipe 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 belt;

[0107] The first end of the filter is connected to the water 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 communicated with the water outlet pipeline via the fourth pressure sensor, the fourth temperature sensor and the second electric heating belt.

[0109] The filtered water after heat exchange enters the outlet pipe after passing through the outlet valve of the heat exchanger, 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.

[0110] By installing multiple sensors (third pressure sensor, third temperature sensor, second temperature sensor, fourth pressure sensor, fourth temperature sensor) in the second pipeline, the system can monitor the water quality, temperature and pressure changes after heat exchange in real time to ensure that the system operates in the best state.

[0111] The filter is used to remove impurities in the water. By filtering the water immediately after it leaves the heat exchanger, the water quality is maintained, scaling and corrosion inside the system are prevented, and the service life of the equipment is extended. The second electric heating belt is used to adjust the outlet water temperature when necessary.

[0112] By precisely controlling the temperature and flow of cooling water, the system can use energy more efficiently, reducing waste while also lowering the impact on the environment.

[0113] In some embodiments, the water outlet pipe and the water inlet pipe may be connected to a cooling device, such as an air conditioner, a liquid cooling cabinet, etc. Specifically, the embodiments of the present application do not limit this.

[0114] The design of connecting the first pipe and the second pipe to the air-cooled heat exchanger realizes the complementary advantages of liquid cooling and air cooling. The liquid can efficiently take away the heat generated by the equipment and dissipate the heat into the air through the air-cooled heat exchanger, which greatly improves the heat dissipation efficiency, effectively reduces the operating temperature of the equipment, improves the performance and reliability of the equipment, and extends the service life of the equipment.

[0115] In one possible implementation of the embodiment of the present 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 disposed between the circulation pump and the first pressure sensor; the second end of the second bypass valve is disposed between the third temperature sensor and the third pressure sensor.

[0118] The main function of the first bypass valve is to bypass the supply and return water to ensure that the outlet water temperature is not lower than the limit value; when the outlet water temperature is detected to be lower than the set threshold, the first bypass valve can be opened to allow 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, when the system is started or stopped, the first bypass valve can be used to balance the water flow in the system, reduce the water hammer effect, and protect the system from damage.

[0119] The second bypass valve mainly controls the supply and return water pressure difference of the system so as not to 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 regulation, such as maintaining a stable pressure when the system load changes.

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

[0121] The first end of the water collecting tray is connected to the wet curtain of the air-cooled heat exchange gas via the water replenishment solenoid valve and the spray water replenishment pump;

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

[0123] The third end of the water collecting tray is communicated with the water drain port via the water drain solenoid valve.

[0124] The water collection pan is the main water source for the sprinkler system. When the wet curtain slowly supplies water, the water replenishment solenoid valve will open, allowing the sprinkler water replenishment pump to draw water from the water collection pan to replenish the wet curtain to enhance the heat exchange effect or for cooling; the third end of the water collection pan is connected to the drain port through the drain solenoid valve, which is used to drain the water in the water collection pan when the system is shut down or needs to be drained.

[0125] In an implementable manner of the embodiment of the present disclosure, the system further comprises a water replenishment pipeline, the water replenishment pipeline comprising a water storage tank, a first hand valve, a water replenishment pump and a second hand valve;

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

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

[0128] Wherein, a water supply hose is arranged between the water supply pump and the first hand valve.

[0129] See also Figure 2 , Figure 2 A schematic diagram of another cooling source system provided in an embodiment of the present application; Figure 2 As shown, the first end of the water replenishment tank is connected to the first end of the water replenishment pump through a first manual valve, and the operator can manually control the first manual valve to open or close the water source of the water replenishment pump, thereby controlling the water replenishment process.

[0130] When the liquid level in the liquid storage tank is lower than the limit value, the liquid storage tank is directly replenished by the water replenishment pump until the high liquid level of the liquid storage tank is reached and the pump is stopped. The water replenishment pump is used for normal water replenishment. When the first pressure detection value is ≤0.08MPa, the system is started to replenish liquid. At this time, the manual valve is opened. When the detection system pressure exceeds 0.11MPa, the water replenishment pump is closed. In an implementable manner of the embodiment of the present disclosure, the water replenishment pipeline also includes a solenoid valve;

[0131] The water storage tank is communicated with the fourth end of the degassing tank via the solenoid valve.

[0132] Please continue reading Figure 1 During the initial water replenishment, determine the first pressure value of the first pressure sensor. When the first pressure value is lower than 0.1Mpa, close the first manual valve, start the water replenishment pump to replenish the system. When the water storage tank is detected to have reached a high liquid level, turn off the water replenishment pump. When the first pressure value is ≤0.08MPa, start replenishing the system. At this time, the first manual valve is opened. When the first pressure value is detected to exceed 0.11MPa, turn off the water replenishment pump. Only when the liquid level in the liquid storage tank is low, an alarm is issued, the first manual valve is closed, and the water replenishment pump is manually started through the water replenishment hose to replenish the liquid until the high liquid level in the liquid storage tank is detected and the pump is automatically stopped.

[0133] In an implementable manner of the embodiment of the present disclosure, the system further includes a first liquid cooling cabinet, a second liquid cooling cabinet and an air conditioner, and the air conditioner includes a condenser;

[0134] 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 with the second end of the first pipeline;

[0135] 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 with the second end of the second pipeline.

[0136] See also Figure 3 , Figure 3 A schematic diagram of another cooling source system provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, a parallel connection is adopted so that the cooling water in the second pipeline can be distributed to multiple liquid cooling cabinets and condensers at the same time, and the cooling water from different liquid cooling cabinets and condensers flows back to the first pipeline. In the event of a failure in a liquid cooling cabinet or a condenser, other components can still work normally, reducing the impact of single point failures on the entire system.

[0137] The air-liquid direct drive device can be directly connected to the liquid-cooled cabinet to provide liquid cooling for the liquid-cooled server; another way is connected to the condenser of the air-cooled inter-row air conditioner to provide air cooling for the server through compression refrigeration.

[0138] See also Figure 4 , Figure 4 A schematic diagram of an air-cooled air conditioner provided in an embodiment of the present application, the air-cooled air conditioner is mainly composed of a fan, an evaporator, an expansion valve, and a plate exchange condenser. The condenser heat exchanges the coolant through a first pipe.

[0139] In one possible implementation of the embodiment of the present disclosure, the system further includes: a cooling distribution unit;

[0140] The first water outlet of the cooling distribution unit and the water outlet of the condenser are connected in parallel with the first end of the first pipe;

[0141] The first water inlet of the cooling distribution unit and the water inlet of the condenser are connected in parallel with the second end of the second pipe;

[0142] The water outlet of the first liquid cooling cabinet and the water outlet of the second liquid cooling cabinet are connected in parallel with the second water inlet of the cooling distribution unit;

[0143] The water inlet of the first liquid cooling cabinet and the water inlet of the second liquid cooling cabinet are connected in parallel with the second water outlet of the cooling distribution unit.

[0144] See also Figure 5 , Figure 5 This is a schematic diagram of another cold source system provided in an embodiment of the present application. In this connection mode, cooling water is distributed to the first liquid cooling cabinet and the second liquid cooling cabinet through a cooling distribution unit (CDU). The cooling water distribution ratio can be determined according to the actual thermal management requirements of the first liquid cooling cabinet and the second liquid cooling cabinet to ensure that the coolant is effectively delivered to the place where heat dissipation is required. The CDU device is equipped with a water pump and a heat exchanger, and the liquid cooling heat dissipation load of the secondary side pipeline and the server is transported through the CDU heat exchanger; another way is connected to the condenser of the air-cooled inter-row air conditioner to provide air cooling for the server through compression refrigeration.

[0145] The spray water tank integrated in the cold heat exchanger is equipped with a drainage solenoid valve, which controls the valve switch according to the ambient temperature T0. When T0 is lower than the first preset value (such as 10°C), an alarm is triggered. When it is lower than the second preset threshold (such as 5°C), the drainage solenoid valve opens to drain the water in the water pan. The anti-freeze alarm is triggered to remind the operation and maintenance personnel to open the drainage in the spray water pump to prevent the water pump from freezing.

[0146] Figure 6 The following is a flow chart of a method for controlling a cold source provided by an embodiment of the present disclosure. Figure 6 As shown, the method is applied to the aforementioned cold source system, and the method comprises the following steps:

[0147] Step 101, obtaining a first outlet water temperature detected by a second temperature sensor.

[0148] The second temperature sensor is installed near the water outlet and is used for real-time monitoring of the outlet water temperature, ie, the first outlet water temperature.

[0149] Step 102: determining a temperature range satisfied by the first outlet water temperature according to a preset temperature level threshold.

[0150] In order to accurately control the water temperature to meet various needs, the temperature range that the first water outlet temperature meets is determined based on the preset temperature level threshold. In some implementable methods, the temperature level threshold can be set according to the maximum temperature and the minimum temperature. For example, if the first water outlet temperature is lower than the low temperature threshold, it is judged 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; if it is higher than the high temperature threshold, it naturally falls into the high temperature range. According to the range, intelligent adjustment is made to ensure that the water temperature is always in an appropriate range.

[0151] Step 103: Controlling 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 satisfies the target outlet water temperature.

[0152] After determining the first outlet water temperature range, 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 increase the water temperature so that it approaches the target outlet water temperature.

[0153] When the first outlet water temperature is in the high temperature range and higher than the target outlet water temperature, the system increases the fan speed to increase heat dissipation to prevent the water temperature from being too high and 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.

[0154] By dynamically adjusting the fan speed of the air-cooled heat exchanger within the temperature range that the first outlet water temperature meets, the system can continuously and stably allow the first outlet water temperature to meet the target outlet water temperature, ensuring that a stable and appropriate water temperature can be provided under various working conditions, such as ensuring stable operation of equipment in industrial cooling systems, or providing users with a comfortable water temperature in domestic hot water supply systems.

[0155] In some embodiments, the preset temperature level threshold includes a first temperature threshold and a second temperature threshold, the second temperature threshold is the target outlet water temperature; and the controlling of the air 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:

[0156] 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 pipe is controlled to supply water to the wet curtain;

[0157] When the first outlet water temperature is greater than the second temperature threshold, it indicates that the current water temperature is too high. In order to quickly reduce the water temperature, the fan speed of the air-cooled heat exchanger is set to the maximum speed to maximize the air flow and enhance the heat dissipation effect. At the same time, in order to further enhance the cooling effect, the spray pipe is controlled to open and water is supplied to the wet curtain. The wet curtain absorbs a lot of heat during the evaporation of water. With the strong ventilation of the fan, it can significantly accelerate the heat dissipation, causing the water temperature to drop rapidly and meet the target outlet water temperature requirements.

[0158] When the first outlet water temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold, controlling the fan speed of the air-cooled heat exchanger so that the first outlet water temperature meets the target outlet water temperature;

[0159] In some embodiments, the minimum water temperature can be set to a first temperature threshold, and the target water temperature can be set to a second temperature threshold. When the first water outlet temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold, it means that the water temperature meets the minimum temperature requirement. Based on the difference between the current first water outlet temperature and the target water outlet temperature, the fan speed is dynamically adjusted to gradually reduce the difference between the two, so that the first water outlet temperature can steadily meet the target water outlet temperature, ensuring that the system always operates in a stable and efficient state.

[0160] When the first outlet water temperature is less than the first temperature threshold, the fan speed of the air-cooled heat exchanger is set to zero.

[0161] When the first outlet water temperature is lower than the first temperature threshold, the water temperature does not meet the minimum temperature requirement, and the fan speed of the air-cooled heat exchanger is set to zero, the fan is stopped, and heat dissipation is reduced.

[0162] By differentially controlling the fan speed of the air-cooled heat exchanger and the spray pipes according to the relationship between the first outlet water temperature and different temperature thresholds, the water temperature can be precisely controlled. Not only can the water temperature be quickly cooled down when it is too high to avoid damage to the equipment due to high temperature and ensure stable operation of the system, but also the fan speed can be flexibly adjusted when the water temperature is moderate to maintain a constant water temperature, improve energy efficiency, and reduce unnecessary energy consumption. At the same time, the fan can be stopped when the water temperature is too low to prevent excessive cooling and protect the overall performance of the equipment and system.

[0163] 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 so that the first outlet water temperature meets the target outlet water temperature, the method further includes:

[0164] Acquire a second outlet water temperature detected by a third temperature sensor;

[0165] When it is determined that the fan speed of the air-cooled heat exchanger is the minimum speed and the time length during which the second outlet water temperature is less than the first temperature threshold is greater than or equal to a preset time length threshold, the first bypass valve is controlled to be opened, 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;

[0166] When the information received by the central control unit indicates that the fan speed of the air-cooled heat exchanger is at the lowest speed state, and the second outlet water temperature continues to be lower than the first temperature threshold for a preset time threshold, it means that the water temperature is too low and fails to recover to the appropriate range by itself within a period of time, the control instruction for the first bypass valve is triggered to control the opening of the first bypass valve, and according to the difference between the current second outlet water temperature and the first temperature threshold, based on the PID control algorithm, the opening of the first bypass valve is dynamically adjusted to make the first pipeline directly connected to the second pipeline without passing through the air-cooled radiator, so that the second outlet water temperature gradually rises until it is greater than or equal to the first temperature threshold and returns to an appropriate temperature range.

[0167] When the first bypass valve reaches the maximum opening and the second outlet water temperature is lower than the first temperature threshold, the pipeline electric heating belt is turned on to perform heating.

[0168] If the first bypass valve has been fully adjusted to its maximum opening, but the second water outlet temperature is still lower than the first temperature threshold, this indicates that the water temperature cannot be effectively increased by simply changing the water flow path. In this extreme case, the pipeline electric heating belt is turned on, and the pipeline electric heating belt is evenly wrapped around the outer walls of the first pipe and the second pipe. The resistance wire inside it will quickly generate heat after being energized, and transfer the heat to the water in the pipe by heat conduction. In some embodiments, the second water outlet temperature is monitored in real time, and the heating power of the electric heating belt is accurately controlled to ensure that the water temperature can rise steadily, and finally reach and maintain at or above the first temperature threshold, to ensure the normal operation and stable operation of the entire system.

[0169] The water temperature is adjusted by intelligently adjusting the opening of the first bypass valve and optimizing the system's own water flow path. When the bypass valve reaches its limit, the electric heating belt of the pipeline intervenes to ensure that the water temperature is always maintained within the appropriate working range. This control solution comprehensively improves the temperature management capability of the system, plays a key role in ensuring the normal operation of the equipment, saving energy, and improving the overall performance of the system, and provides a reliable and efficient temperature control solution.

[0170] Optionally, after controlling the speed of a fan of the air-cooled heat exchanger according to the temperature range satisfied by the first outlet water temperature, the method further includes:

[0171] Determine a difference between a first pressure value detected by the first pressure sensor and a second pressure value detected by the second pressure sensor, and control the frequency of the circulation pump according to the difference to eliminate the pressure difference between the first pressure value and the second pressure value;

[0172] When there is a difference between the first pressure value and the second pressure value, it indicates that there is pressure imbalance in the circulation system. Based on the PID control algorithm, the frequency of the circulation pump is regulated according to the size and change trend of the pressure difference.

[0173] If the difference is positive, it means that the first pressure value is higher than the second pressure value, and the system will reduce the frequency of the circulation pump and reduce the amount of fluid delivered, thereby reducing the first pressure value; conversely, if the difference is negative, the system will increase the frequency of the circulation pump and increase the fluid flow to increase the second pressure value. Through this dynamic adjustment, the pressure difference between the two pressure values ​​is gradually eliminated, ensuring the stability of the pressure of the circulation system, ensuring the normal operation of each device in the system, and avoiding equipment damage or reduced efficiency due to uneven pressure.

[0174] When the frequency of the circulation pump is the lowest frequency, the second bypass valve is controlled to open, 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,

[0175] When the frequency of the circulating pump has been reduced to the minimum, but the pressure difference between the first pressure value and the second pressure value has not been eliminated, the current pressure imbalance problem cannot be solved by adjusting the frequency of the circulating pump. At this time, the second bypass valve is controlled to open, and the opening of the second bypass valve is dynamically adjusted according to the real-time pressure difference and system operation status. By changing the flow rate and flow rate of the fluid in the bypass pipeline, the overall pressure distribution of the system is changed.

[0176] The temperature difference between the second temperature threshold and the third water outlet temperature detected by the fourth temperature sensor is determined, and the frequency of the circulation pump is controlled.

[0177] When the temperature difference is positive, that is, the third outlet water temperature is lower than the second temperature threshold, it means that the system needs more heat transfer, and the system will increase the frequency of the circulation pump. Increasing the circulation speed of the fluid allows more heat to be brought to the required area, thereby increasing the third outlet water temperature. Conversely, if the temperature difference is negative, that is, the third outlet water temperature is higher than the second temperature threshold, the system will reduce the frequency of the circulation pump and reduce heat transfer.

[0178] Accurately monitoring the pressure values ​​of the first pressure sensor and the second pressure sensor and adjusting the frequency of the circulation pump according to the difference can quickly and effectively balance the pressure in the system, ensure that each device operates in a stable pressure environment, avoid equipment damage, leakage and other failures caused by uneven pressure, and extend the service life of the equipment. When the circulation pump reaches the lowest frequency and there is still a pressure difference, the pressure balance is ensured by opening and adjusting the opening of the second bypass valve, which enhances the system's ability to cope with complex pressure conditions and improves the stability and reliability of the system's operation. The circulation pump frequency is controlled based on the temperature difference between the second temperature threshold and the third outlet water temperature, achieving precise control of the system temperature and ensuring that the water temperature is always maintained in an appropriate range. This not only optimizes the system's heat exchange efficiency, but also provides reliable protection for processes or equipment that rely on stable water temperatures.

[0179] Optionally, after controlling the speed of a fan of the air-cooled heat exchanger according to the temperature range satisfied by the first outlet water temperature, the method further includes:

[0180] When the ambient temperature is lower than the third temperature threshold, the spray pipe is controlled to close to supply water to the wet curtain;

[0181] When the ambient temperature sensor detects that the ambient temperature is lower than the preset third temperature threshold, the wet curtain spraying water supply will cause unnecessary energy consumption. Closing the water supply valve of the spray pipe ensures that no water flows to the wet curtain, thereby avoiding unnecessary spraying operations in a low temperature environment and ensuring the rational use of energy.

[0182] In some embodiments, the third temperature threshold is an empirical value, which can be set according to actual needs, such as being set to 30 degrees or 33 degrees, etc. Specifically, this embodiment of the present application does not limit this.

[0183] When the ambient temperature is higher than the third temperature threshold, the spray pipe is controlled to supply water to the wet curtain.

[0184] When the ambient temperature sensor detects that the ambient temperature is higher than the third temperature threshold, the water evaporation of the wet curtain is required to reduce the ambient air temperature to meet the system's demand for ambient temperature regulation.
