Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to a method and related equipment for circulating cooling of equipment. Background Technology

[0002] Equipment cooling is crucial in industrial production and daily operation, as temperature affects equipment performance and lifespan. In high-temperature environments, electronic components in equipment are prone to electron migration, leading to signal errors, calculation deviations, and accelerated material aging, thus shortening equipment lifespan. Mechanical parts in the equipment may experience jamming or wear due to deteriorated lubricating oil and thermal expansion of metals.

[0003] In existing technologies, cooling water or coolant is typically used to cool equipment, primarily due to its excellent thermal conductivity. Water has a high specific heat capacity, allowing it to absorb a large amount of heat with minimal temperature change, thus efficiently removing heat generated by the equipment. Coolant is further optimized from cooling water by adding various additives to enhance its cooling performance. However, the cooling control mechanisms in existing technologies are not optimal. Some cooling systems operate at maximum power regardless of the actual heat generated by the equipment, resulting in excessive energy consumption. Other cooling systems fail to consider the impact of sudden temperature changes in the equipment, leading to inadequate cooling control mechanisms. Summary of the Invention

[0026] As described in the background section, high-density computing clusters in the power industry integrate a large number of high-power computing devices, resulting in a dramatic increase in heat generation per unit space. Uncontrolled temperature can trigger multiple risks, necessitating strict temperature control. Excessive temperatures accelerate chip aging due to thermal stress, leading to performance degradation or even permanent damage. Simultaneously, the failure rate of electronic components increases exponentially, raising the risk of equipment downtime and directly impacting the continuity of critical services such as power dispatching and smart grid analysis. Furthermore, high temperatures force cooling systems to operate under overload, significantly increasing energy consumption and worsening the data center's PUE (Power Usage Effectiveness). Therefore, cooling high-density computing clusters in the power industry is essential.

[0027] In existing technologies, cooling water or coolant is typically used to cool equipment, primarily due to its excellent thermal conductivity. Water has a high specific heat capacity, allowing it to absorb a large amount of heat with minimal temperature change, thus efficiently removing heat generated by the equipment. Coolant is further optimized from cooling water by adding various additives to enhance cooling performance. However, the cooling control mechanisms in existing technologies are not optimal. Some cooling systems operate at maximum power regardless of the actual heat generated by the equipment, resulting in excessive energy consumption. Other cooling systems fail to consider the impact of sudden temperature changes in the equipment; in the event of such changes, the original liquid control parameters are ineffective in cooling the equipment, leading to an inefficient cooling control mechanism.

[0028] In view of this, embodiments of this application propose a method for circulating cooling of equipment, referring to... Figure 1 This includes the following steps:

[0029] Step 101: Perform multiple cooling operations on the equipment to be cooled. Each cooling operation is performed as follows: Obtain the outdoor ambient temperature of the area where the equipment to be cooled is located.

[0030] In this step, to ensure stable operation of the equipment, it is necessary to cool the equipment to maintain it within a suitable operating temperature range. The equipment to be cooled is in operation; that is, cooling is required as soon as the equipment is turned on. Because the heat generated by the components in the equipment varies depending on the events processed, the larger the data volume corresponding to the event, the greater the heat generated by the components. Therefore, dynamic cooling is required throughout the entire operation of the equipment. Multiple rounds of cooling operations are performed on the equipment to be cooled. Each round of cooling operations is executed as follows: obtaining the outdoor ambient temperature of the area where the equipment to be cooled is located. This application uses cooling water to cool the coolant, and uses the cooled coolant to cool the equipment. The temperature of the cooling water is affected by the outdoor ambient temperature. For example, the cooling water temperature is low in winter and low in summer. The temperature of the cooling water is positively correlated with the outdoor ambient temperature, and since cooling water is used to cool the coolant, the temperature of the coolant is also positively correlated with the outdoor ambient temperature. By obtaining the outdoor ambient temperature, we can demonstrate the impact of outdoor ambient temperature on cooling water and coolant.

[0031] Step 102: Based on the outdoor ambient temperature, determine the first liquid control parameter, and control the liquid to cool the equipment to be cooled according to the first liquid control parameter, wherein the liquid includes cooling water and coolant.

[0032] In this step, a first liquid control parameter is determined based on the outdoor ambient temperature. Since the outdoor ambient temperature affects the temperature of the cooling water and coolant, this first liquid control parameter can be determined according to the outdoor temperature. For example, in winter, the low outdoor temperature leads to a low cooling water temperature, which in turn leads to a low coolant temperature, providing a good cooling basis for both the cooling water and coolant. In summer, the high outdoor temperature leads to a high cooling water temperature, which in turn leads to a high coolant temperature, providing a poor cooling basis for both the cooling water and coolant. Based on the above, the first liquid control parameter for the cooling water and coolant is determined. The liquid is then controlled to cool the equipment according to the first liquid control parameter. By considering the influence of natural factors on the liquid and determining the first liquid control parameter, the purpose of accurately determining the first liquid control parameter is achieved. Furthermore, by using the first liquid control parameter to control the liquid to cool the equipment, energy consumption can be effectively reduced, achieving the goal of precise cooling of the equipment.

[0033] It should be noted that this application utilizes both cooling water and coolant to cool the equipment, employing a dual-loop cooling system. If only coolant is used, it circulates in a single loop within the equipment's cooling circuit, absorbing heat generated during operation and causing its temperature to rise continuously. The high-temperature coolant carries a large amount of heat energy; if it continues to circulate directly, it cannot effectively remove the heat from the equipment and may even cause overheating and damage, requiring frequent start-ups and shutdowns of the liquid temperature regulating device. Since the outdoor ambient temperature regulates the temperature of the cooling water, this application introduces cooling water to cool the coolant, utilizing a natural cold source to save energy for cooling the equipment. The temperature of the cooling water is affected by the outdoor ambient temperature. The cooling water enters a specialized heat exchange device, such as a plate heat exchanger or a shell-and-tube heat exchanger. In the heat exchanger, the high-temperature coolant and the low-temperature cooling water achieve heat transfer through a specific flow channel design. The coolant transfers its own heat to the cooling water, gradually decreasing its temperature; while the cooling water absorbs heat and its temperature rises. The cooled water that has completed the heat exchange is discharged through a drain pipe for reuse. After being cooled by the heat exchanger, the coolant returns to a suitable temperature range and flows back into the equipment's cooling circuit. It then flows again through the heat-generating parts of the equipment, such as engine cylinder liners and heat sinks in electronic devices, quickly absorbing the heat generated by the equipment due to its excellent thermal conductivity, thus maintaining the equipment temperature within a safe operating range. This application provides a dual-cycle collaborative control method for a single-phase immersion liquid cooling system for low-carbon, high-reliability integrated computer computing devices. The single-phase immersion liquid cooling system is a highly efficient heat dissipation technology where the equipment is completely immersed in a special insulating coolant, and heat is removed through coolant circulation while the coolant remains liquid throughout the heat dissipation process. Based on the outdoor ambient temperature, first liquid control parameters are determined, and then the liquid is controlled to cool the equipment according to these parameters, ensuring stable and efficient cooling, avoiding energy waste. The cooling water and coolant work together to provide reliable temperature protection for the equipment. This application achieves the linkage adjustment of dual-cycle parameters, significantly improving the utilization rate of the cold source and the heat dissipation efficiency of the equipment.

[0034] Step 103: Obtain multiple first coolant temperatures at the coolant outlet within a predetermined time period.

[0035] In this step, the coolant is used to directly cool the equipment. If the coolant temperature continues to rise, it indicates that the equipment is generating relatively much heat. To maintain the equipment at a suitable operating temperature, the fluid control parameters need to be changed. First, multiple first coolant temperatures at the coolant outlet are obtained within a predetermined time period. These multiple first coolant temperatures reflect the change in coolant temperature within the predetermined time period. The predetermined time period is determined based on historical experience.

[0036] Step 104: Based on the plurality of first coolant temperatures, perform multiple rounds of monitoring operations. Each round of monitoring operations is performed as follows: Based on the plurality of first coolant temperatures and the predetermined time period, determine the temperature change rate.

[0037] In this step, since the temperature changes of the equipment are unpredictable, multiple rounds of monitoring are required based on multiple first coolant temperatures to ensure that temperature changes are monitored. For example, when the equipment load suddenly changes (e.g., server power jumps from 20% to 80%), the temperature change can reach ±5°C. Each round of monitoring is performed as follows: based on multiple first coolant temperatures and a predetermined time period, the temperature change rate is determined. For example, the temperature change rate is obtained by dividing the difference between the last and first first coolant temperatures by the predetermined time period. This allows for accurate determination of the temperature change rate using actual values. The temperature change rate reflects the amount of temperature change per unit time, and this temperature change is used to monitor the heat changes of the equipment.

[0038] Step 105: In response to determining that the absolute value of the temperature change rate is less than or equal to the first predetermined change rate, obtain multiple second coolant temperatures at the coolant outlet within the next predetermined time period, use the multiple second coolant temperatures as multiple first coolant temperatures in the next round of monitoring operations, and execute the next round of monitoring operations.

[0039] In this step, if the absolute value of the temperature change rate is less than or equal to the first predetermined change rate, it indicates that the heat of the equipment to be cooled has not changed significantly in a short period of time. Therefore, it is necessary to obtain multiple second coolant temperatures at the coolant outlet for the next predetermined time period and continue monitoring. The first predetermined change rate is determined based on historical experience. The multiple second coolant temperatures from the current round are used as multiple first coolant temperatures for the next round of monitoring. Through multiple rounds of monitoring, it is ensured that rapid changes in the heat of the equipment to be cooled can be monitored in a timely manner.

[0040] Step 106: In response to determining that the absolute value of the temperature change rate is greater than the first predetermined change rate, based on the temperature change rate and the plurality of first coolant temperatures, a second liquid control parameter is determined, and the liquid is controlled to cool the device to be cooled according to the second liquid control parameter and the predetermined cooling time. The current round of monitoring operation is exited, and the next round of cooling operation is executed.

[0041] In this step, if the absolute value of the temperature change rate is greater than the first predetermined change rate, it indicates that the heat of the equipment to be cooled has changed relatively significantly in a short period of time, and the heat of the equipment to be cooled may increase or decrease rapidly. The temperature change rate reflects the amount of temperature change per unit time, and multiple first coolant temperatures reflect the current coolant temperature. Based on the temperature change rate and multiple first coolant temperatures, second liquid control parameters are determined. According to the second liquid control parameters and the predetermined cooling time, the liquid is controlled to cool the equipment to be cooled. When the heat of the equipment to be cooled increases rapidly, to ensure the stable operation of the equipment, the temperature of the equipment to be cooled needs to be reduced rapidly. Therefore, the heat consumed when controlling the liquid through the second liquid control parameters is relatively large. However, controlling the liquid through the second liquid control parameters for a long time will lead to increased energy consumption. When the heat of the equipment to be cooled decreases rapidly, the heat consumed when controlling the liquid through the second liquid control parameters is relatively small, avoiding excessive cooling and energy waste. However, controlling the liquid through the second liquid control parameters for a long time will result in ineffective cooling of the equipment to be cooled. Therefore, after the predetermined cooling time, the temperature of the equipment to be cooled has been effectively changed, and the current round of monitoring operation needs to be exited to execute the next round of cooling operation. The predetermined cooling time is determined based on historical experience, ensuring effective cooling of the equipment after this time. Through multiple rounds of cooling operations, natural cold sources are introduced into the cooling process, effectively reducing energy consumption. Simultaneously, considering the possibility of sudden temperature changes, multiple monitoring operations are performed, allowing for timely adjustments to the liquid control parameters. This ensures the equipment remains in a stable operating state, guaranteeing the rationality of the cooling control mechanism.

[0042] It should be noted that the process of cooling the coolant with cooling water in this application is a primary closed-loop cooling water circulation, while the process of cooling the equipment with coolant is a secondary open-loop coolant circulation. For example... Figure 2 As shown, the primary side flow can be: liquid temperature regulating equipment (e.g., a dry cooler with a fan) → variable frequency water pump → plate heat exchanger water side → dry cooler. The above equipment operates under pressure, and the pressure is monitored in real time by a pressure sensor. The pressure range is 0.3–0.5 MPa. Figure 3As shown, the secondary side's composition can be: liquid-cooled cabinet (immersion server side) → variable frequency liquid pump → plate heat exchanger liquid side → Tank (a container for storing or immersing coolant, an open-type liquid storage tank). The tank has an open design: liquid level fluctuations of ±5cm are monitored by a liquid level gauge with a resolution of 1cm. The coolant flow rate (target 0.5–2 m / s) is controlled by adjusting the liquid pump frequency (10–50Hz), and the tank buffers heat load fluctuations. This application is applicable to dynamic heat dissipation, energy efficiency optimization, and autonomous controllable operation assurance for high-density computing clusters in the power industry. Through dual-cycle collaboration, multi-mode refined control, and dynamic prediction mechanisms, this application significantly improves the control accuracy and energy efficiency of the open-type liquid cooling system, exhibiting stronger scenario adaptability and technological advancement.

[0043] The above scheme involves multiple rounds of cooling operations on the equipment to be cooled. Each round of cooling operations is performed as follows: The outdoor ambient temperature of the area where the equipment is located is obtained; based on the outdoor ambient temperature, a first liquid control parameter is determined, and the liquid is controlled to cool the equipment according to the first liquid control parameter. The liquid includes cooling water and coolant; multiple first coolant temperatures at the coolant outlet within a predetermined time period are obtained; based on the multiple first coolant temperatures, multiple rounds of monitoring operations are performed. Each round of monitoring operations is performed as follows: Based on the multiple first coolant temperatures and the predetermined time period, the temperature change rate is determined; in response to determining that the absolute value of the temperature change rate is less than or equal to a first predetermined change rate, multiple second coolant temperatures at the coolant outlet within the next predetermined time period are obtained, and these multiple second coolant temperatures are used as multiple first coolant temperatures in the next round of monitoring operations. The next round of monitoring operations is then executed; in response to determining that the absolute value of the temperature change rate is greater than the first predetermined change rate, a second liquid control parameter is determined based on the temperature change rate and the multiple first coolant temperatures. The liquid is controlled to cool the equipment according to the second liquid control parameter and the predetermined cooling time, the current round of monitoring operations is exited, and the next round of cooling operations is executed.

[0044] In some embodiments, the first liquid control parameter includes a first control parameter corresponding to the cooling water and a second control parameter corresponding to the coolant; determining the first liquid control parameter based on the outdoor ambient temperature and controlling the liquid to cool the device to be cooled according to the first liquid control parameter includes: determining a working mode for cooling the device to be cooled based on the outdoor ambient temperature; determining the first control parameter and the second control parameter according to the working mode; controlling the water volume and temperature change of the cooling water according to the first control parameter, and controlling the liquid volume change of the coolant according to the second control parameter; using the controlled cooling water to cool the controlled coolant, and using the cooled coolant to cool the device to be cooled.

[0045] In this embodiment, the operating mode of the device to be cooled is determined based on the outdoor ambient temperature. Different outdoor ambient temperatures have different effects on cooling water; therefore, multiple operating modes can be determined according to the outdoor ambient temperature. This application uses both cooling water and coolant to cool the device. Therefore, the first liquid control parameters include a first control parameter corresponding to the cooling water and a second control parameter corresponding to the coolant. Different operating modes have different first liquid control parameters; the first and second control parameters are determined based on the operating mode. The volume and temperature of the cooling water are controlled according to the first control parameter, and the volume of the coolant is controlled according to the second control parameter. The controlled cooling water is used to cool the controlled coolant, and the cooled coolant is used to cool the device. This application uses a dual circulation of cooling water and coolant to cool the device, taking into account the influence of outdoor ambient temperature on the cooling process and utilizing natural cold sources to reduce energy consumption for cooling the device.

[0046] In some embodiments, the operating mode is a low-temperature operating mode; the first control parameter includes the load of a first liquid temperature regulating device and a first water pump frequency, and the second control parameter includes the frequency of a first sub-liquid pump and a second sub-liquid pump; determining the first control parameter and the second control parameter according to the operating mode includes: in response to determining that the operating mode is the low-temperature operating mode, calculating the load of the first liquid temperature regulating device based on the outdoor ambient temperature, the rated load of the liquid temperature regulating device, and a first adjustment coefficient; calculating the frequency of the first water pump based on the rated frequency of the water pump and the second adjustment coefficient; obtaining the third coolant temperature at the coolant outlet and the first power of the device to be cooled; in response to determining that the third coolant temperature is greater than a first predetermined temperature, calculating the frequency of the first sub-liquid pump based on the first power, the rated power of the device to be cooled, the rated frequency of the liquid pump, and the third adjustment coefficient; in response to determining that the third coolant temperature is less than or equal to the first predetermined temperature, determining the predetermined frequency as the frequency of the second sub-liquid pump.

[0047] In this embodiment, existing technologies typically only consider the impact of relatively high indoor ambient temperatures on equipment cooling, requiring increased cooling efforts. While increased cooling efforts are unnecessary when indoor or outdoor ambient temperatures are relatively low, existing technologies do not consider utilizing natural cold sources. This application utilizes natural cold sources in a low-temperature operating mode. Relatively low outdoor ambient temperatures result in lower cooling water temperatures; therefore, considering natural cold sources, the first and second control parameters are rationally determined. The cooling water temperature can be adjusted using a liquid temperature regulating device, such as a dry cooler; the cooling water flow rate can be adjusted using a water pump. By adjusting the cooling water temperature and flow rate, the coolant can be effectively cooled. The first control parameters include the first liquid temperature regulating device load and the first water pump frequency. A relatively high liquid temperature regulating device load indicates a relatively large adjustment to the cooling water temperature; a relatively high water pump frequency indicates a relatively large cooling water flow rate, and consequently, a relatively large volume of cooling water. Coolant has a relatively complex composition. Changing the temperature of cooling water using a liquid temperature regulating device is more energy-efficient than changing the temperature of coolant. Furthermore, directly heating the coolant can lead to evaporation, and frequent operation of the coolant may pose safety risks. Therefore, this application only requires using a liquid temperature regulating device to change the temperature of the cooling water, and subsequently using the cooling water to change the temperature of the coolant. For example, the liquid temperature regulating device is a dry cooler. The flow rate of the coolant can be regulated by a liquid pump. The second control parameters include the frequency of the first sub-liquid pump and the frequency of the second sub-liquid pump. A relatively high liquid pump frequency indicates a relatively high coolant flow rate, and consequently, a relatively large volume of coolant.

[0048] The load of the first liquid temperature regulating equipment is calculated based on the outdoor ambient temperature and the first adjustment coefficient. Since the outdoor ambient temperature affects the cooling water temperature, this influence must be considered when adjusting the cooling water temperature. The rated load of the liquid temperature regulating equipment refers to the maximum load that the equipment can withstand for long-term, safe, and stable operation under normal working conditions. The first load ratio is determined based on the outdoor ambient temperature and the first adjustment coefficient. Using this first load ratio and the rated load of the liquid temperature regulating equipment, the load of the first liquid temperature regulating equipment is determined, maximizing the utilization of natural cooling sources and reducing energy consumption. The load of the first liquid temperature regulating equipment is determined using the following formula:

[0049] Q1 = X1 * (T1 - T0)% * Q e Formula 1,

[0050] Where Q1 is the load of the first liquid temperature regulating device, X1 is the first regulating coefficient (e.g., X1 is 0.8), T1 is the predetermined maximum temperature corresponding to the low-temperature operating mode (e.g., T1 is 25℃), T0 is the outdoor ambient temperature, and Q e This is the rated load for the liquid temperature regulating equipment.

[0051] For example, when the outdoor ambient temperature is 20°C, the first load ratio is 0.8*(25-20)%=4%, where the first adjustment coefficient is 0.8, and the maximum predetermined temperature corresponding to the low temperature mode is 25°C.

[0052] The rated frequency of a water pump refers to the maximum frequency that the pump can withstand for long-term, safe, and stable operation under normal working conditions. Water pumps have variable frequency accuracy, for example, ±0.1Hz. Based on the rated frequency and a second adjustment coefficient, the first pump frequency is determined using the following formula:

[0053] H1 = X2 * H e1 Formula 2,

[0054] Where H1 is the frequency of the first water pump, X2 is the second adjustment coefficient, and H e1 The rated frequency of the water pump. For example, X2 is 0.6, resulting in a relatively low cooling water flow rate. Due to the relatively low outdoor ambient temperature, the cooling effect of the cooling water is relatively good, eliminating the need for a relatively large first liquid temperature regulating equipment load and a first water pump frequency control to regulate the cooling water temperature and flow rate. The liquid temperature regulating equipment operates at a low load, and the water pump operates at a low frequency.

[0055] The third coolant temperature at the coolant outlet is obtained to determine the heat generated by the equipment to be cooled. If the third coolant temperature is higher than the first predetermined temperature (e.g., 35°C), it indicates that the equipment generates relatively more heat, requiring adjustment of the pump frequency. The first power is the power of the equipment to be cooled at the current moment. The ratio of the first power to the rated power of the equipment is the load rate. The load rate reflects the workload of the equipment. A relatively high current power indicates a relatively heavy workload and significant heat generation during operation. Therefore, when cooling the equipment, the current power must be considered to balance energy efficiency and heat dissipation reliability, dynamically matching load changes. Directly using the current power to determine the pump frequency would lead to abnormal pump frequency; therefore, the pump frequency is determined using the load rate calculated from the current power. If the aforementioned load rate is greater than the predetermined minimum load rate, the aforementioned load rate is determined as the target load rate; if the aforementioned load rate is less than or equal to the predetermined minimum load rate, the predetermined minimum load rate is determined as the target load rate. For example, the predetermined minimum load rate is 10%. The rated power of the equipment to be cooled refers to the maximum power that the equipment to be cooled can withstand for long-term, safe, and stable operation under normal working conditions. Based on the first power, the rated power of the equipment to be cooled, the rated frequency of the liquid pump, and the third adjustment coefficient, the frequency of the first sub-liquid pump is determined by the following formula:

[0056] H2 = P% * X3 * H e2 Formula 3,

[0057] Where H2 is the frequency of the first sub-pump, P% is the target load rate, X3 is the third adjustment coefficient, and H e2 This is the rated frequency of the liquid pump.

[0058] When the temperature of the third coolant is less than or equal to the first predetermined temperature, it indicates that the heat of the equipment to be cooled is relatively low, and there is no need to adjust the frequency of the liquid pump. The frequency adjustment function of the liquid pump is turned off, and heat dissipation relies on the natural convection of the liquid pump. At this time, the frequency of the liquid pump is a fixed frequency, and the predetermined frequency (i.e., the aforementioned fixed frequency) is determined as the frequency of the second sub-liquid pump. In low-temperature operating mode, the influence of natural cold source is introduced, and the first and second control parameters are reasonably determined, which helps to reduce the energy consumption for cooling the equipment.

[0059] It should be noted that the rated load of the liquid temperature regulating equipment, the rated frequency of the water pump, the rated power of the equipment to be cooled, and the rated frequency of the liquid pump are all data that have been marked before the equipment leaves the factory and can be directly obtained. The first regulation coefficient, the second regulation coefficient, the third regulation coefficient, the first preset temperature, the preset maximum temperature, and the preset minimum load rate are all determined based on historical experience.

[0060] In some embodiments, the operating mode is a medium-temperature operating mode; the first control parameter includes the load of the second liquid temperature regulating device and the frequency of the second water pump, and the second control parameter includes the frequency of the second liquid pump; determining the first control parameter and the second control parameter according to the operating mode includes: in response to determining that the operating mode is the medium-temperature operating mode, calculating the initial load of the second liquid temperature regulating device based on the outdoor ambient temperature, the rated load of the liquid temperature regulating device, and a fourth adjustment coefficient, wherein the fourth adjustment coefficient is greater than the first adjustment coefficient; calculating the initial second liquid pump frequency based on the rated frequency of the liquid pump and a fifth adjustment coefficient; obtaining the second power of the device to be cooled, and based on the second power... The load rate corresponding to the equipment to be cooled is determined based on the load rate and the rated power of the equipment to be cooled; in response to determining that the load rate is less than a predetermined load rate, the initial second liquid temperature regulating equipment load is determined as the second liquid temperature regulating equipment load, and the initial second liquid pump frequency is determined as the second liquid pump frequency; in response to determining that the load rate is greater than or equal to the predetermined load rate, the initial second liquid temperature regulating equipment load is increased based on a first increase coefficient to obtain the second liquid temperature regulating equipment load, and the initial second liquid pump frequency is increased based on a second increase coefficient to obtain the second liquid pump frequency; the second water pump frequency is determined based on the second liquid pump frequency and a sixth adjustment coefficient.

[0061] In this embodiment, a single operating mode is not conducive to energy conservation. This application refines the operating mode based on the outdoor ambient temperature, implementing different control mechanisms for different outdoor ambient temperatures. Therefore, the operating mode in this application also includes a medium-temperature operating mode. The refined control mechanism designed for different outdoor ambient temperatures results in high-power cooling consumption even under low load. In the medium-temperature operating mode, the outdoor ambient temperature is relatively suitable. At this time, regardless of whether the outdoor environment is low or high, the impact on the cooling water is relatively small. Therefore, the first and second control parameters corresponding to the medium-temperature operating mode are determined.

[0062] The first control parameter includes the load of the second liquid temperature regulating equipment and the frequency of the second water pump. The second control parameter includes the frequency of the second liquid pump. The initial load of the second liquid temperature regulating equipment is calculated based on its rated load and the fourth adjustment coefficient. Since the outdoor ambient temperature corresponding to the medium-temperature operating mode has a relatively small impact on the cooling water temperature, the liquid temperature regulating equipment load needs to be relatively larger than that corresponding to the low-temperature operating mode to achieve the same cooling effect. Therefore, the fourth adjustment coefficient is greater than the first adjustment coefficient. The second load ratio is determined based on the outdoor ambient temperature and the fourth adjustment coefficient. The second liquid temperature regulating equipment load is then determined using the second load ratio and the rated load of the liquid temperature regulating equipment. The initial load of the second liquid temperature regulating equipment is determined using the following formula:

[0063]

[0064] Where Q2 is the initial load of the second liquid temperature regulating device, and X 41 The fourth adjustment coefficient includes the first sub-fourth adjustment coefficient, T2 is the predetermined judgment temperature corresponding to the medium temperature operating mode, and X 42 This is the second sub-fourth adjustment coefficient included in the fourth adjustment coefficient.

[0065] For example, when the outdoor ambient temperature is 30°C, the second load ratio is: Among them, the first sub-fourth adjustment coefficient is 5, the second sub-fourth adjustment coefficient is 1.2, and the predetermined judgment temperature corresponding to the medium temperature working mode is 20℃.

[0066] Based on the rated frequency of the liquid pump and the fifth adjustment coefficient, the initial second liquid pump frequency is determined using the following formula:

[0067] H3 = X5 * H e2 Formula 5

[0068] Where H3 is the initial second pump frequency, and X5 is the fifth adjustment coefficient, for example, X5 is 0.5.

[0069] Obtain the second power of the device to be cooled, where the second power is the power of the device at the current moment. Based on the second power and the rated power of the device, determine the corresponding load rate of the device. If the load rate is less than the predetermined load rate, for example, the predetermined load rate is 50%, it means that the heat generated by the device is relatively small, and it is not necessary to further increase the load of the liquid temperature regulating equipment and the frequency of the liquid pump. The initial second liquid temperature regulating equipment load and the initial second liquid pump frequency are directly determined as the second liquid temperature regulating equipment load and the second liquid pump frequency. If the load rate is greater than or equal to the predetermined load rate, it means that the heat generated by the device is relatively large, and in order to ensure the cooling effect, it is necessary to further increase the load of the liquid temperature regulating equipment and the frequency of the liquid pump. Based on the first increase coefficient, determine the load increase amount, for example, the first increase coefficient is 15%. Increase the initial second liquid temperature regulating equipment load according to the load increase amount to obtain the second liquid temperature regulating equipment load. Based on the second increase coefficient, determine the frequency increase amount, for example, the second increase coefficient is 20%. Increase the initial second liquid pump frequency according to the frequency increase amount to obtain the second liquid pump frequency. The ratio of water pump to liquid pump frequency is adjusted in real time to ensure maximum heat exchange efficiency of the plate heat exchanger. The water pump frequency is determined in relation to the liquid pump frequency. Based on the second liquid pump frequency and the sixth adjustment coefficient, the second water pump frequency is determined using the following formula:

[0070] Formula 6: H5 = H4 * X6

[0071] Where H5 is the second water pump frequency, H4 is the second liquid pump frequency, and X6 is the sixth adjustment coefficient, for example, X6 is 1.1. In medium-temperature operating mode, rationally determining the first and second control parameters is beneficial for energy saving in cooling the equipment.

[0072] It should be noted that, to meet the basic requirements for cooling the equipment, a minimum pump frequency needs to be set, for example, 30%. If the calculated pump frequency is lower than the minimum frequency, the minimum frequency should be used instead of the calculated frequency. Simultaneously, the natural convection heat transfer mechanism should be triggered (the liquid pump frequency converter should be turned off). The operating parameters of the equipment used for cooling must not exceed its rated operating parameters. Furthermore, the cooling water level should be monitored. If the cooling water level is lower than a predetermined level (e.g., half the height at full load), it indicates that the pressure sensor threshold has been reached. The calculated pump frequency should then be reduced by a predetermined reduction percentage (e.g., 10%) to minimize the impact of liquid-side flow fluctuations on the liquid level.

[0073] It should be noted that the fourth adjustment coefficient, the fifth adjustment coefficient, the sixth adjustment coefficient, the predetermined load rate, the first increase coefficient, the second increase coefficient, the predetermined judgment temperature, the predetermined water volume height, and the predetermined reduction ratio are all determined based on historical experience.

[0074] In some embodiments, the operating mode is a high-temperature operating mode; the first control parameter includes the load of the third liquid temperature regulating device, the frequency of the third water pump, and the load of the standby liquid temperature regulating device; the second control parameter includes the frequency of the third liquid pump and the amount of liquid added; determining the first control parameter and the second control parameter according to the operating mode includes: in response to determining that the operating mode is the high-temperature operating mode, determining the load of the third liquid temperature regulating device based on the rated load of the liquid temperature regulating device; calculating the frequency of the third water pump based on the rated frequency of the water pump and a seventh adjustment coefficient, wherein the seventh adjustment coefficient is greater than the second adjustment coefficient; determining the frequency of the third liquid pump based on the rated frequency of the liquid pump; obtaining the fourth coolant temperature at the coolant outlet; in response to determining that the fourth coolant temperature is greater than a second predetermined temperature, determining the load of the standby liquid temperature regulating device based on the rated load of the liquid temperature regulating device; detecting the actual liquid level of the coolant; in response to determining that the actual liquid level is less than a predetermined liquid level, calculating the amount of cooling water added based on the actual liquid level and the predetermined liquid level.

[0075] In this embodiment, the prior art only considers the impact of indoor ambient temperature on the heat dissipation of the cooling equipment when the indoor ambient temperature is relatively high, without considering the impact of outdoor ambient temperature on the cooling water when the outdoor ambient temperature is relatively high. Therefore, this application determines a first control parameter and a second control parameter for the high-temperature operating mode. The first control parameter includes the load of the third liquid temperature regulating device, the frequency of the third water pump, and the load of the standby liquid temperature regulating device. The second control parameter includes the frequency of the third liquid pump and the amount of liquid added. In the high-temperature operating mode, the relatively high outdoor ambient temperature not only affects the temperature of the cooling water but may also affect the indoor ambient temperature. Considering both of these situations, it is necessary to increase the cooling intensity of the equipment to be cooled. Figure 4 As shown, the rated load of the liquid temperature regulating equipment is determined as the load of the third liquid temperature regulating equipment, so that the liquid temperature regulating equipment operates at full load. Based on the rated frequency of the water pump and the seventh regulation coefficient, the frequency of the third water pump is calculated using the following formula:

[0076] H6 = H e1 *X7 Formula Seven,

[0077] Where H6 is the third water pump frequency and X7 is the seventh adjustment coefficient, for example, X7 is 0.9. Since the outdoor ambient temperature corresponding to the high-temperature operating mode has a relatively large impact on the cooling water temperature and the equipment to be cooled, the water pump frequency needs to be relatively higher than the water pump frequency corresponding to the low-temperature operating mode to achieve the same cooling effect. Therefore, the seventh adjustment coefficient needs to be greater than the second adjustment coefficient. For example, a seventh adjustment coefficient of 90% allows the water pump to operate close to full power. By using the third liquid temperature regulation equipment load and the third water pump frequency to control the cooling water temperature and flow rate, the cooling effect of the cooling water is increased. The rated frequency of the liquid pump is determined as the third liquid pump frequency, allowing the liquid pump to operate at full power.

[0078] The fourth coolant temperature at the coolant outlet is obtained. If this fourth coolant temperature is higher than a second predetermined temperature (e.g., 50°C), it indicates that the equipment generates relatively much heat, requiring the activation of the backup liquid temperature regulating device for cooling. The rated load of the backup liquid temperature regulating device is set as its load, ensuring it operates at full capacity to prioritize heat dissipation and ensure equipment safety. Conversely, insufficient coolant volume will also result in poor cooling. Therefore, the actual coolant level is detected. If the actual level is lower than a predetermined level, the required amount of coolant to be added is calculated based on both the actual and predetermined levels. For example, the predetermined level is 80% of the coolant level at full load. Furthermore, this application uses pressure sensors and level gauges to monitor the tank's pressure and level in real time. For example, when the pressure is lower than a predetermined atmospheric pressure (e.g., -0.5 kPa), the air supply valve is opened to replenish the pressure; when the coolant level is lower than a first predetermined coolant level (e.g., the first predetermined coolant level is 50% of the coolant level at full load), the water pump frequency is reduced. The frequency of the fifth pump is determined using the following formula: Where H7 is the frequency of the fifth liquid pump, H6 is the frequency of the third water pump obtained through the aforementioned calculation, and X 81 For example, X is the first sub-eighth adjustment coefficient. 81 At 25℃, X 82 For example, X is the second sub-eighth adjustment coefficient. 82 For 10, X 83 For example, X is the third sub-eighth adjustment coefficient. 83The coolant tank in this application is not completely sealed and is easily affected by ambient temperature fluctuations. Therefore, a dedicated pressure and level control mechanism has been designed to address the shortcomings of open-type coolant management in existing technologies, demonstrating significant practicality and innovation. By using the first and second control parameters corresponding to the high-temperature operating mode, the equipment can be rapidly cooled.

[0079] If the backup liquid temperature regulating device is always on, it will increase energy consumption. Therefore, a shutdown mechanism needs to be set for the backup liquid temperature regulating device. After determining the load of the backup liquid temperature regulating device based on its rated load, the method further includes: continuously acquiring a sixth cooling temperature at the coolant outlet; for each sixth cooling temperature, in response to determining that the sixth cooling temperature is less than a predetermined cooling temperature, for example, a predetermined cooling temperature of 45°C, shutting down the backup liquid temperature regulating device, and reducing the backup liquid temperature regulating device to zero.

[0080] This application addresses different operating modes by implementing different controls for the liquid temperature regulating equipment, water pump, and liquid pump. (I) Liquid temperature regulating equipment control: Based on the outdoor ambient temperature and multiple coolant temperatures at the coolant outlet under different operating modes, the load of the liquid temperature regulating equipment is dynamically adjusted to achieve reasonable utilization of the cold source. In low-temperature mode, natural cold source is utilized; in medium-temperature mode, the load is calculated based on the coolant temperature; in high-temperature mode, it operates at full load and activates the backup cold source when the temperature exceeds the limit. (II) Water pump control: Linked with the liquid pump frequency, a reasonable flow ratio between the water side and the liquid side is maintained through the aforementioned formula six or eight to ensure heat exchange efficiency. Simultaneously, when the liquid level is lower than the first predetermined liquid level (for example, the first predetermined liquid level is obtained by multiplying the liquid level when the coolant is fully loaded by 50%), the water pump frequency is reduced to reduce flow fluctuations. (III) Liquid pump control: The frequency is dynamically adjusted based on the load rate and multiple coolant temperatures at the coolant outlet. A first minimum lower limit is set in low-temperature mode; a second minimum lower limit is set in medium-temperature mode, and a first derivative prediction is introduced; in high-temperature mode, a forced 100% frequency is implemented. When the coolant temperature is ≤ the first predetermined temperature, the variable frequency pump is turned off, and natural convection is used for heat dissipation.

[0081] It should be noted that the seventh adjustment coefficient, the predetermined liquid level, the predetermined atmospheric pressure, the first predetermined liquid level, the first sub-eighth adjustment coefficient, the second sub-eighth adjustment coefficient, the third sub-eighth adjustment coefficient, and the predetermined cooling temperature are all determined based on historical experience.

[0082] In some embodiments, the second liquid control parameter includes the load of a fourth liquid temperature regulating device or a fifth liquid temperature regulating device corresponding to the cooling water, and the frequency of a fourth liquid pump corresponding to the coolant; determining the second liquid control parameter based on the temperature change rate and the plurality of first coolant temperatures includes: in response to determining that the temperature change rate is greater than a second predetermined change rate, and that there is a first coolant temperature among the plurality of first coolant temperatures that is lower than a first predetermined temperature, adjusting the load of the liquid temperature regulating device corresponding to the first liquid control parameter based on a positive adjustment parameter to obtain the fourth liquid temperature regulating device load; in response to determining that the temperature change rate is less than a third predetermined change rate, and that there is a first coolant temperature among the plurality of first coolant temperatures that is greater than a second predetermined temperature, adjusting the load of the liquid temperature regulating device corresponding to the first liquid control parameter based on a first negative adjustment parameter to obtain the fifth liquid temperature regulating device load; and adjusting the frequency of the liquid pump corresponding to the first liquid control parameter based on a second negative adjustment parameter to obtain the fourth liquid pump frequency.

[0083] In this embodiment, when the temperature change rate is greater than the second predetermined change rate (where the second predetermined change rate is a positive number, for example, 0.1℃ / s), and when there is a first coolant temperature lower than the first predetermined temperature among the multiple first coolant temperatures (for example, the first predetermined temperature is 45℃), it indicates that the equipment generates relatively a lot of heat. The presence of a first coolant temperature lower than the first predetermined temperature indicates that the heat generated by the equipment is still within a controllable range, and rapid cooling of the equipment is not required. The second liquid control parameter includes the load of the fourth liquid temperature regulating device corresponding to the coolant.

[0084] Based on the positive adjustment parameter, the load of the liquid temperature regulating equipment corresponding to the first liquid control parameter is adjusted to obtain the fourth liquid temperature regulating equipment load. This includes: within a first predetermined period, based on the positive adjustment parameter, performing at least one round of first adjustment operation on the liquid temperature regulating equipment load corresponding to the first liquid control parameter to obtain the fourth liquid temperature regulating equipment load. Each round of first adjustment operation is performed as follows: within the first predetermined period, the liquid temperature regulating equipment load is adjusted according to the positive adjustment parameter to obtain the first target liquid temperature regulating equipment load; according to the first target liquid temperature regulating equipment load, the liquid is controlled to cool the equipment to be cooled; after a predetermined adjustment time, multiple fifth coolant temperatures at the coolant outlet within the first predetermined period are obtained; based on the multiple fifth coolant temperatures and the first predetermined period, a second temperature change rate is determined; in response to determining that the second temperature change rate is greater than the fourth predetermined change rate, the first target liquid temperature regulating equipment load of the current round is used as the liquid temperature regulating equipment load in the next round, and the next round of first adjustment operation is executed; in response to determining that the second temperature change rate is less than or equal to the fourth predetermined change rate, the first target liquid temperature regulating equipment load is used as the fourth liquid temperature regulating equipment load, and the current round of first adjustment operation is exited.

[0085] Since rapid cooling of the equipment is not required, and a relatively large increase in the load of the liquid temperature regulating equipment would lead to an increase in its energy consumption, at least one round of first adjustment operation is performed on the liquid temperature regulating equipment load corresponding to the first liquid control parameter within a first predetermined period, for example, a first predetermined period of 5 seconds, based on the positive adjustment parameter, to obtain a fourth liquid temperature regulating equipment load. Each round of first adjustment operation is performed as follows: Within the first predetermined period, the liquid temperature regulating equipment load is adjusted according to the positive adjustment parameter to obtain a first target liquid temperature regulating equipment load, for example, an increase of 5%. The liquid is controlled to cool the equipment to be cooled according to the first target liquid temperature regulating equipment load. After a predetermined adjustment time, the adjustment effect is determined, and multiple fifth coolant temperatures at the coolant outlet within the first predetermined period are obtained. Based on the multiple fifth coolant temperatures and the first predetermined period, a second temperature change rate is determined. If the second temperature change rate is greater than the fourth predetermined change rate, it indicates that the change in heat generated by the equipment is still large, and the equipment temperature needs to be further adjusted; for example, the fourth predetermined change rate is 0.05℃ / s. The load of the first target liquid temperature regulating equipment in the current round is used as the load for the liquid temperature regulating equipment in the next round, and the first regulation operation in the next round is executed. If the second temperature change rate is less than or equal to the fourth predetermined change rate, it indicates that the change in the amount of heat generated by the equipment has decreased. The first target liquid temperature regulating equipment is then used as the fourth liquid temperature regulating equipment load, and the first regulation operation in the current round is terminated. Through at least one round of first regulation operation, the purpose of effectively cooling the equipment is achieved under the premise of energy saving.

[0086] If the temperature change rate is less than the third predetermined change rate (where the third predetermined change rate is negative, for example, -0.1℃ / s), and one of the multiple first coolant temperatures is higher than the second predetermined temperature (e.g., the second predetermined temperature is 30℃), it indicates that the reduction in heat generation by the equipment is relatively large. The existence of a first coolant temperature higher than the second predetermined temperature indicates that the heat generation by the equipment is still within a controllable range, and rapid temperature adjustment is not necessary. Since the temperature change rate is negative, it indicates that the heat generation by the equipment is decreasing. Therefore, it is necessary not only to precisely adjust the load of the temperature regulating equipment and the frequency of the liquid pump to reduce energy consumption, but also to ensure that the adjusted load of the temperature regulating equipment and the frequency of the liquid pump can still effectively cool the equipment.

[0087] Based on the first negative adjustment parameter, the load of the liquid temperature regulating equipment corresponding to the first liquid control parameter is adjusted to obtain the fifth liquid temperature regulating equipment load. Also, based on the second negative adjustment parameter, the pump frequency corresponding to the first liquid control parameter is adjusted to obtain the fourth pump frequency. This includes: within a second predetermined period, based on the first and second negative adjustment parameters, performing at least one round of second adjustment operations on the liquid temperature regulating equipment load and pump frequency corresponding to the first liquid control parameter to obtain the fifth liquid temperature regulating equipment load and the fourth pump frequency. Specifically, each round of second adjustment operations is performed as follows: within the second predetermined period, the liquid temperature regulating equipment load is adjusted according to the first negative adjustment parameter to obtain the second target liquid temperature regulating equipment load; the pump frequency is adjusted according to the second negative adjustment parameter to obtain the target pump frequency. Frequency; according to the second target liquid temperature regulating equipment load and the target liquid pump frequency, control the liquid to cool the equipment to be cooled; after a predetermined adjustment time, obtain multiple sixth coolant temperatures at the coolant outlet within a second predetermined period, and determine a third temperature change rate based on the multiple sixth coolant temperatures and the second predetermined period; in response to determining that the third temperature change rate is less than a fifth predetermined change rate, use the second target liquid temperature regulating equipment load of the current round as the liquid temperature regulating equipment load of the next round, and use the target liquid pump frequency of the current round as the liquid pump frequency of the next round, and execute the second adjustment operation of the next round; in response to determining that the third temperature change rate is less than or equal to the fifth predetermined change rate, use the second target liquid temperature regulating equipment load as the fifth liquid temperature regulating equipment load, use the target liquid pump frequency as the fourth liquid pump frequency, and exit the second adjustment operation.

[0088] Since rapid cooling of the equipment is not required, and rapid changes in the load of the liquid temperature regulating equipment would increase its energy consumption, at least one round of first adjustment operation is performed on the liquid temperature regulating equipment load corresponding to the first liquid control parameter within a second predetermined period, for example, a second predetermined period of 5 seconds, based on the first negative adjustment parameter and the second negative adjustment parameter, to obtain the fourth liquid temperature regulating equipment load. Each round of second adjustment operation is performed as follows: within the second predetermined period, the liquid temperature regulating equipment load is adjusted according to the first negative adjustment parameter to obtain the second target liquid temperature regulating equipment load; the pump frequency is adjusted according to the second negative adjustment parameter to obtain the target pump frequency; for example, the first negative adjustment parameter is a reduction of 3%, and the second negative adjustment parameter is a reduction of 5%. The liquid is controlled to cool the equipment to be cooled according to the second target liquid temperature regulating equipment load and the target pump frequency. After a predetermined adjustment time, the adjustment effect is determined, and multiple fifth coolant temperatures at the coolant outlet within the second predetermined period are obtained. Based on the multiple fifth coolant temperatures and the second predetermined period, a third temperature change rate is determined. If the third temperature change rate is less than the fifth predetermined change rate (e.g., the fifth predetermined change rate is -0.05℃ / s), it indicates that the heat generated by the equipment is still relatively large, requiring continued temperature adjustment. The load of the second target liquid temperature regulating equipment in the current round is used as the load for the liquid temperature regulating equipment in the next round, and the target liquid pump frequency in the current round is used as the liquid pump frequency for the next round, executing the second adjustment operation. If the third temperature change rate is greater than or equal to the fifth predetermined change rate, it indicates that the heat generated by the equipment is decreasing. The load of the second target liquid temperature regulating equipment is used as the fifth liquid temperature regulating equipment load, and the target liquid pump frequency is used as the fourth liquid pump frequency, exiting the second adjustment operation. Through multiple rounds of adjustment operations, the load of the liquid temperature regulating equipment is gradually reduced, achieving effective cooling of the equipment while saving energy. By calculating the temperature change rate in real time and predicting temperature change trends in advance, proactive control is achieved, significantly reducing temperature overshoot and response delay compared to traditional single-point threshold control. Specific effects can be summarized as: ① Fast response speed: Adjustment begins before the temperature reaches the threshold, shortening the response time. ② Minimal overshoot: Through early intervention, the temperature overshoot during sudden load changes is effectively reduced, from ±5℃ in existing technologies to within ±2℃. ③ Optimized energy consumption: Over-adjustment and frequent start-stop cycles are avoided, reducing energy consumption while ensuring effective heat dissipation.

[0089] In addition, the second liquid control parameter may also include the fourth pump frequency. Based on the target liquid pump frequency calculated in each round of the second adjustment operation, the fourth pump frequency in each round of the second adjustment operation is determined by Formula 8. In each round of the second adjustment operation, the equipment load and the target liquid pump frequency are adjusted according to the second target liquid temperature. While controlling the liquid to cool the equipment to be cooled, the liquid is also controlled to cool the equipment to be cooled according to the fourth pump frequency.

[0090] This application utilizes a three-dimensional control model of "ambient temperature-load power-cycle state" to achieve dynamic heat dissipation and energy efficiency optimization of high-density server clusters through the coordinated control of primary closed-loop water circulation and secondary open-loop coolant circulation. By integrating multi-dimensional parameters for control decisions, the control becomes more precise and intelligent, surpassing the single-parameter or limited-parameter control of existing technologies.

[0091] It should be noted that the data for the second predetermined rate of change, the first predetermined temperature, the third predetermined rate of change, the second predetermined temperature, the predetermined adjustment time, the positive adjustment parameter, the first predetermined cycle, the fourth predetermined rate of change, the second predetermined temperature, the first negative adjustment parameter, the second negative adjustment parameter, the second predetermined cycle, and the fifth predetermined rate of change are all determined based on historical experience.

[0092] In some embodiments, determining the working mode for cooling the device to be cooled based on the outdoor ambient temperature includes: searching for the working mode corresponding to the outdoor ambient temperature in a pre-built correspondence between outdoor ambient temperature and working modes.

[0093] In this embodiment, since different outdoor ambient temperatures have varying effects on equipment cooling, existing technologies only consider the impact of relatively high outdoor ambient temperatures on equipment heat dissipation, without considering the influence of outdoor ambient temperature on cooling water. This application determines different operating modes based on different outdoor ambient temperatures, pre-establishing a correspondence between outdoor ambient temperature and operating mode to achieve dynamic allocation of cold source resources. For example, when the outdoor ambient temperature is less than or equal to 25°C, the operating mode is a low-temperature operating mode, maximizing the utilization of natural cold sources; when the outdoor ambient temperature is greater than 25°C but less than or equal to 35°C, the operating mode is a medium-temperature operating mode, balancing energy efficiency and heat dissipation reliability; when the outdoor ambient temperature is greater than 35°C, the operating mode is a high-temperature operating mode, prioritizing heat dissipation safety. By fully considering the impact of different outdoor ambient temperatures on equipment cooling, optimal energy efficiency ratios can be achieved under different outdoor ambient temperatures, ensuring both precise equipment cooling and effective energy saving.

[0094] In another embodiment provided in this application, the solution in this application can be further improved. For example, a sensor redundancy design scheme, such as dual level gauge cross-validation or redundant temperature sensor configuration, can improve system reliability and avoid malfunctions caused by a single sensor failure. Figure 5 As shown, the system acquires identical data from the main sensor and its corresponding redundant sensor. When the data deviation between the main sensor and the redundant sensor exceeds a threshold (e.g., temperature sensor deviation > 1℃), it automatically switches to the redundant sensor and triggers an alarm. The fault is located using a fault location algorithm. Control parameters are compensated based on historical data averages. When the reading deviation between the main level gauge and the redundant level gauge exceeds 2cm, it automatically switches to the redundant level gauge and generates an alarm signal; control parameters are compensated based on historical averages.

[0095] In addition, energy efficiency optimization algorithms can be introduced: reinforcement learning can be used to dynamically optimize parameters (such as flow ratio) with the goal of reducing PUE to below 1.1. "Using ambient temperature, load power, and dry cooler load as state variables, water pump / liquid pump frequency as action variables, and PUE value as the reward function, deep reinforcement learning can be used to achieve dynamic parameter optimization, with PUE ≤ 1.1 set as the convergence target."

[0106] 3. Typical Scenario Examples

[0107] Scenario: Sudden increase in server power during low-temperature operation

[0108] Initial conditions: outdoor ambient temperature is 20℃, load rate is 20%, liquid pump frequency is 12% of the rated frequency of the liquid pump, and dry cooler load is 4% of the rated load.

[0109] Emergency situation: The load rate suddenly increased to 60%, and the coolant temperature at the coolant outlet rose from 30℃ to 38℃, with a temperature change rate of 0.3℃ / s.

[0110] Control Response:

[0111] The pump frequency immediately increases to 36% of the pump's rated frequency. Since 38℃ > 35℃, 60% × 0.6 = 36%.

[0112] Dry cooler load: Based on the first derivative, it is predicted to increase by 15% (4% + 15% = 19%), which is 19% of the rated load.

[0113] In addition, based on the liquid pump frequency, the water pump frequency needs to be linked to 36%×1.3+50%=96.8%, which is rounded up to 97%.
