[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0024] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied to the intelligent control of the cooling system of a data center.

[0025] According to research, the control method of the cooling system of the data center is usually: when the indoor temperature is higher than the set temperature value, the water pump is controlled to start running and the outdoor dry cooler is powered on; when the indoor temperature is lower than the set temperature value, the water pump is controlled to stop working and the outdoor fan is powered off to ensure the constant temperature of the data center. However, during this adjustment process, the parameters of the refrigeration equipment in the cooling system vary greatly, and the temperature and flow in the cooling circuit fluctuate greatly, resulting in a large change in the system power, which not only increases the energy consumption of the refrigeration equipment, but also causes damage to the refrigeration equipment.

[0026] Based on this, embodiments of the present application provide a cooling system and a control method thereof, an electronic device, and a storage medium.

[0027] The cooling system here is specifically the cooling system of the data center, which is used to ensure that the operating temperature of the servers in the data center remains at a constant temperature. The servers in the data center are mostly set in cabinets or liquid cooling cabinets. The heat load of the cabinet is a dynamic variable. As the amount of data processed and the external ambient temperature change, the size of the heat load changes and its ability to adjust the heat load also changes. In order to achieve on-demand cooling of the heat load of the data center, achieve energy-saving effects and ensure the stable operation of the data center, it is necessary to intelligently control the cooling system of the data center.

[0028] See also Figure 1 , Figure 1The following is a flow chart of a method for controlling a cooling system provided in an embodiment of the present application. Figure 1 As shown in , the control method of the cooling system provided by the embodiment of the present application includes:

[0029] S101 , respectively determining an ambient temperature value and a temperature value of a water outlet of a cooler, wherein the ambient temperature value is a temperature value of a room where a server is located.

[0030] The ambient temperature here refers to the temperature of the room where the server is located, that is, the indoor temperature of the data center.

[0031] S102: Determine a regulation mode of the cooling system according to the determined ambient temperature value and the temperature value of the water outlet of the cooler.

[0032] See also Figure 2 , Figure 2 A flowchart of a step of determining an adjustment mode provided in an embodiment of the present application. In this step, the step of determining the adjustment mode of the cooling system according to the determined ambient temperature value and the temperature value of the water outlet of the cooler specifically includes:

[0033] S1010: Compare the ambient temperature value with a second preset temperature value.

[0034] S1012. When the ambient temperature value is greater than the second preset temperature value, the temperature value of the water outlet of the cooler is compared with the first preset temperature value, wherein the second preset temperature value is less than the first preset temperature value.

[0035] First, determine the range of the ambient temperature value. The second preset temperature value is generally set between 30°C and 40°C. In this embodiment, the second preset temperature value is 32°C. If the ambient temperature value is greater than the second preset temperature value, it means that the ambient temperature in the current data center is high. The first preset temperature value is generally set between 30°C and 45°C. In this embodiment, the first preset temperature value is 35°C.

[0036] When the ambient temperature value is not greater than the second preset temperature value, no adjustment is performed.

[0037] S1014: When the temperature value of the water outlet of the cooler is greater than the first preset temperature value, it is determined that the regulation mode of the cooling system is the frequency increase regulation mode.

[0038] S1016: When the temperature value of the water outlet of the cooler is less than the first preset temperature value, it is determined that the regulation mode of the cooling system is a frequency reduction regulation mode.

[0039] Here, when the water outlet temperature of the cooler 30 is greater than the first preset temperature value, it means that the data processing capacity of the server is high, and the cooler of the cooling system is smaller than the operating heat of the server, then the cooling capacity of the cooling system needs to be increased. When the water outlet temperature value of the cooler 30 is less than the first preset temperature value, it means that the current data processing capacity of the server is low, and the cooling capacity of the cooling system is greater than the operating heat of the server, then the cooling capacity of the cooling system can be appropriately reduced to save energy. If the temperature value of the water outlet of the cooler 30 is equal to the first preset temperature value, no adjustment is performed.

[0040] S103. When the regulation mode of the cooling system is the frequency-increasing regulation mode, the first operating frequency of the first controlled object in the frequency-increasing regulation mode is determined based on the temperature difference of the liquid outlet of the liquid cooling cabinet within a preset time interval, and the first controlled object is controlled to operate at the first operating frequency to reduce the temperature of the server.

[0041] In step S103, the step of determining the first operating frequency of the first controlled object in the frequency increase adjustment mode based on the temperature difference of the liquid outlet of the liquid cooling cabinet 10 within a preset time interval specifically includes:

[0042] The temperature variation coefficient is determined based on the temperature difference of the liquid outlet of the liquid cooling cabinet 10 within a preset time interval. The temperature variation coefficient is compared with the preset temperature variation coefficient. When the temperature variation coefficient is greater than the preset temperature variation coefficient, the step of determining the first operating frequency of the first controlled object in the frequency increase adjustment mode is performed.

[0043] Specifically, the temperature variation coefficient is determined by the following method:

[0044] The ratio between the temperature difference of the liquid outlet of the liquid cooling cabinet 10 within a preset time interval and the preset time interval is calculated as the temperature variation coefficient.

[0045] If the temperature variation coefficient is not greater than the preset temperature variation coefficient, no adjustment is performed.

[0046] It is understandable that the control method here can be executed in a loop, and the ambient temperature value is obtained according to a preset time interval, and the execution starts according to step S1010 for each ambient temperature value obtained. The liquid outlet of the liquid cooling cabinet 10 here is also obtained according to a preset time interval, and the ratio of the difference between the first temperature value of the liquid cooling cabinet 10 obtained last time and the second temperature value of the liquid cooling cabinet 10 obtained currently to the preset time interval is equivalent to the first-order derivative. According to the first-order derivative, the temperature change trend of the dry cooler outlet can be determined, and prediction and accurate judgment can be achieved, so as to achieve stable operation of the data center, small temperature fluctuations, and small system power fluctuations, and improve the reliability of product components and data center equipment.

[0047] Specifically, the first controlled object includes a liquid pump, a water pump and a cooler, the first operating frequency includes a first liquid pump operating frequency, a first water pump operating frequency and a cooler operating frequency, and the first liquid pump operating frequency is determined by:

[0048] The first liquid pump operating frequency is calculated according to the product of the first adjustment coefficient, the inverse of the temperature difference between the temperature value of the liquid inlet of the heat exchanger and the temperature value of the liquid outlet of the heat exchanger, and the current operating frequency of the liquid pump.

[0049] The calculation formula of the first liquid pump operating frequency F1 is:

[0050]

[0051] Among them, P, K1, and A are fixed values, P is the number of poles of the liquid pump, K1 is the safety factor of the liquid pump, A is the fluid density, f1 is the current operating frequency of the liquid pump 40, and ΔT1 is the temperature difference between the temperature value of the liquid inlet of the heat exchanger 20 and the temperature value of the liquid outlet of the heat exchanger 20.

[0052] And the operating frequency of the first water pump is determined by:

[0053] The first water pump operating frequency is calculated according to the product of the second adjustment coefficient, the inverse of the temperature difference between the temperature value of the water outlet of the heat exchanger and the temperature value of the water inlet of the heat exchanger, and the current operating frequency of the water pump.

[0054] The calculation formula of the first water pump operating frequency F2 is:

[0055]

[0056] Among them, P, K2, and A are fixed values, P is the number of poles of the water pump, K2 is the safety factor of the water pump, A is the fluid density, f2 is the current operating frequency of the water pump 50, and ΔT2 is the temperature difference between the temperature value of the water outlet of the heat exchanger 20 and the temperature value of the water inlet of the heat exchanger 20.

[0057] Specifically, the operating frequency of the cooler is determined by the following method:

[0058] The operating frequency of the cooler is calculated based on the second adjustment coefficient, the inverse of the temperature difference between the temperature value of the water outlet of the heat exchanger and the temperature value of the water inlet of the heat exchanger, and the product of the preset ratios, wherein the preset ratio is the ratio between the indoor temperature value and the first preset temperature value.

[0059] The calculation formula of the cooler operating frequency F3 is:

[0060]

[0061] Among them, P, K2, and A are fixed values, P is the number of water pump poles, K2 is the water pump safety factor, A is the fluid density, ΔT2 is the temperature difference between the temperature value of the water outlet of the heat exchanger 20 and the temperature value of the water inlet of the heat exchanger 20, T0 is the ambient temperature value, and M is the first preset temperature value.

[0062] Specifically, the operating frequency here is the operating frequency of the fan of the cooler 30 .

[0063] In the frequency-up regulation mode, the operating frequencies of the cooler 30, the water pump 50 and the liquid pump 40 are increased at the same time, the fluid temperature at the water inlet of the heat exchanger 20 is lower and the flow rate is increased, and the flow rate at the liquid outlet of the heat exchanger 20 is increased, so that the fluid in the second circuit and the fluid in the first circuit can quickly exchange heat in the heat exchanger 20, and the temperature of the fluid flowing out of the liquid outlet of the heat exchanger 20 is reduced, thereby reducing the temperature of the server and making it work in a constant temperature environment.

[0064] See also Figure 3 , Figure 3 A flowchart of another cooling system control method provided in an embodiment of the present application.

[0065] S201. Determine an ambient temperature value and a temperature value of a water outlet of a cooler respectively. The ambient temperature value is a temperature value of a room where a server is located.

[0066] S202: Determine a regulation mode of the cooling system according to the determined ambient temperature value and the temperature value of the water outlet of the cooler.

[0067] S203: When the adjustment mode of the cooling system is the frequency reduction adjustment mode, determine a second operating frequency of the second controlled object in the frequency reduction adjustment mode, and control the second controlled object to operate at the second operating frequency to reduce the temperature of the server.

[0068] In this step, the second controlled object includes a liquid pump and a water pump, the second operating frequency includes a second liquid pump operating frequency and a second water pump operating frequency, and the second liquid pump operating frequency is determined by:

[0069] The second liquid pump operating frequency is calculated according to the product of the temperature value of the water outlet of the cooler, the inverse of the first preset temperature value and the current operating frequency of the liquid pump.

[0070] The calculation formula of the second liquid pump operating frequency F4 here is:

[0071]

[0072] Wherein, N is the first preset temperature value, f4 is the current operating frequency of the liquid pump 40 , and T1 is the temperature value of the water outlet of the cooler 30 .

[0073] And the operating frequency of the second water pump is determined by:

[0074] The second water pump operating frequency is calculated according to the product of the temperature value of the water outlet of the cooler, the inverse of the first preset temperature value and the current operating frequency of the water pump.

[0075] The calculation formula of the second water pump operating frequency F5 is:

[0076]

[0077] Wherein, N is the first preset temperature value, f5 is the current operating frequency of the water pump 50 , and T1 is the temperature value of the water outlet of the cooler 30 .

[0078] In the frequency reduction adjustment mode, the operating frequencies of the water pump 50 and the liquid pump 40 are increased at the same time, the fluid flow at the water inlet of the heat exchanger 20 is reduced, and the flow at the liquid outlet of the heat exchanger 20 is reduced, so that the fluid in the second circuit and the fluid in the first circuit exchange heat in the heat exchanger 20, thereby reducing the temperature of the server and making it work in a constant temperature environment. Compared with the frequency increase adjustment mode, it can ensure the cooling effect while reducing the power consumption of the cooling system.

[0079] After step S103 or S203 , the process waits to obtain the next ambient temperature value and executes step S1010 .

[0082] A server is placed in the liquid cooling cabinet 10, the hot fluid side of the heat exchanger 20 forms a first loop with the liquid cooling cabinet 10, and the cold fluid side of the heat exchanger 20 forms a second loop with the cooler 30. The hot fluid side is provided with a liquid outlet and a liquid inlet, and the cold fluid side is provided with a water outlet and a water inlet. The liquid pump 40 is arranged between the liquid outlet of the heat exchanger 20 and the liquid inlet of the liquid cooling cabinet 10, and the water pump 50 is arranged between the water outlet of the cooler 30 and the water inlet of the heat exchanger 20. The controller 60 is respectively connected to the water pump 50, the liquid pump 40 and the cooler 30.

[0083] in, Figure 4 The arrows in FIG. 1 are used to indicate the flow direction of the fluid in the first circuit and the second circuit.

[0084] The controller 60 determines the ambient temperature value and the temperature value of the water outlet of the cooler 30 respectively. The ambient temperature value is the temperature value of the room where the server is located. The controller 60 determines the adjustment mode of the cooling system according to the determined ambient temperature value and the temperature value of the water outlet of the cooler 30.

[0085] When the regulation mode of the cooling system is the up-frequency regulation mode, the controller 60 determines the first liquid pump frequency of the liquid pump 40, the first water pump frequency of the water pump 50 and the cooler operating frequency of the cooler 30 in the up-frequency regulation mode based on the temperature difference of the liquid outlet of the liquid cooling cabinet 10 within a preset time interval, and controls the liquid pump 40 to operate at the first liquid pump frequency, the water pump 50 to operate at the first water pump frequency and the cooler 30 to operate at the cooler operating frequency, so as to reduce the temperature of the server.
