[0002] With the rapid development of new-generation information and communication technologies such as the Internet, cloud computing, big data, and artificial intelligence, computing centers that provide data services are experiencing rapid growth. In order for servers to operate normally, they need to continuously dissipate heat to prevent them from overheating and causing malfunctions. However, the energy consumption of the cooling control system used for heat dissipation accounts for approximately 40% of the total energy consumption of the servers. Therefore, there is currently a problem of high energy consumption in the operation of the cooling control system. Summary of the Invention

[0003] Based on this, the purpose of the embodiments of the present application is to provide a refrigeration control system, method, electronic device and storage medium, which can reduce the switching frequency of the working state of the refrigeration control system by formulating a refrigeration strategy and cooperating with a cold storage module to cool the working equipment, thereby reducing the operating energy consumption of the refrigeration control system.

[0004] In a first aspect, an embodiment of the present application provides a refrigeration control system, comprising:

[0005] A refrigeration module, a cold storage module and a control module; wherein the control module is communicatively connected to the refrigeration module and the cold storage module respectively;

[0006] The refrigeration module is used to provide cold capacity to cool the working equipment;

[0007] The cold storage module is used to cooperate with the refrigeration module to perform refrigeration based on the refrigeration demand of the working equipment, or to store the cold energy released by the refrigeration module;

[0008] The control module is used to control the refrigeration module and the cold storage module to provide cold capacity based on a first refrigeration strategy;

[0009] The first cooling strategy may include:

[0010] Controlling the refrigeration module to release cooling capacity based on a first required cooling capacity at a first moment; wherein the first required cooling capacity is determined based on the cooling capacity required by each of the working devices and a cooling correction factor, or based on the cooling capacity required by each component of the working device and the cooling correction factor;

[0011] Obtaining a second required cooling capacity of the working equipment at a second moment, and comparing the second required cooling capacity with the first required cooling capacity to obtain a comparison result; wherein the second moment is a moment after any interval of the first moment;

[0012] When the comparison result indicates that the second required cooling capacity is greater than the sum of the first required cooling capacity and the current cooling capacity of the cooling storage device, controlling the cooling module to increase the cooling capacity; and

[0013] When the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cooling storage device reaches the maximum cooling capacity, the cooling module is controlled to reduce the cooling capacity.

[0014] In the above implementation process, the working equipment can be cooled and cooled based on the formulated cooling strategy. The working condition change of the cooling module is controlled only in two cases: when the increase in the cooling demand of the server is greater than the cooling capacity of the current cold storage module, or when the cooling demand of the server decreases and the cooling capacity stored in the cold storage module reaches the maximum. This can reduce the switching frequency of the working state of the refrigeration control system, thereby reducing the operating energy consumption of the refrigeration control system.

[0015] Optionally, the first cooling strategy may further include:

[0022] and controlling the refrigeration module and the cold storage module to provide cold capacity based on a second refrigeration strategy;

[0023] The second cooling strategy includes:

[0024] Controlling the refrigeration module to release cooling capacity based on a first required cooling capacity at a first moment; wherein the first required cooling capacity is determined based on the cooling capacity required by each of the working devices and a cooling correction factor, or based on the cooling capacity required by each component of the working device and the cooling correction factor;

[0025] Obtaining a second required cooling capacity of the working equipment at a second moment, and comparing the second required cooling capacity with the first required cooling capacity to obtain a comparison result; wherein the second moment is a moment after any interval of the first moment;

[0026] When the comparison result indicates that the second required cooling capacity is greater than the sum of the first required cooling capacity and the cooling capacity currently provided by the cold storage device, controlling the refrigeration module to increase the cooling capacity;

[0027] When the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cooling storage device reaches the maximum cooling capacity, the cooling module is controlled to reduce the cooling capacity.

[0028] In the above implementation process, the amount of cold that the cold storage module can safely provide can be determined based on the safety factor of the cold storage module, and based on this, the working state of the cold storage module can be controlled to cooperate with the refrigeration module to cool down the working equipment in a safe state, which can improve the control accuracy and safety of the refrigeration control system.

[0029] Optionally, the refrigeration module may include at least one air-cooled refrigeration module and at least one liquid-cooled refrigeration module, and both the air-cooled refrigeration module and the liquid-cooled refrigeration module are communicatively connected to the control module.

[0031] The method may include:

[0032] At a first moment, the control module controls the refrigeration module to release cooling capacity based on a first required cooling capacity; wherein the first required cooling capacity is determined based on the cooling capacity required by each of the working devices and a cooling correction factor, or based on the cooling capacity required by each component of the working device and the cooling correction factor;

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. For example, the flowcharts and block diagrams in the accompanying drawings illustrate the possible architectures, functions, and operations of the systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each box in the flowchart or block diagram may represent a module, program segment, or portion of code, which contains one or more executable instructions for implementing the specified logical functions. It should also be noted that in some alternative implementations, the functions marked in the boxes may also occur in an order different from that marked in the drawings. For example, two consecutive boxes may actually be executed substantially in parallel, or they may sometimes be executed in the opposite order, depending on the functions involved. It should also be noted that each box in the block diagram and / or flowchart, as well as the combination of boxes in the block diagram and / or flowchart, may be implemented using a dedicated hardware-based system that performs the specified functions or actions, or may be implemented using a combination of dedicated hardware and computer instructions. In addition, the functional modules in the various embodiments of the present invention may be integrated together to form a separate part, or each module may exist separately, or two or more modules may be integrated to form a separate part.

[0056] During the research process, the applicant found that currently, the data center refrigeration control system's heat monitoring of the computer room mostly focuses on the server inlet and outlet temperatures and the refrigeration control system's inlet and return air temperatures. The monitoring of the computer room heat and server temperature is inaccurate. In order to reduce the impact of monitoring errors on the server, the refrigeration control system adopts a high-power operation method, and the total cooling capacity is usually higher than the actual cooling capacity required.

[0057] Secondly, most existing data centers experience localized hotspots when their load fluctuates significantly. This is because factors such as the cooling control system piping can cause temperature delays in the room, making it difficult to achieve optimal cooling. To reduce the risk of overheating in data centers, the cooling control system is typically operated at high power.

[0058] In addition, the cooling capacity currently required by the server is not well matched with the cooling capacity provided by the refrigeration control system. At the same time, there is a lack of effective and reasonable refrigeration control system control strategies. The refrigeration control system will usually choose to operate at high power, and the total cooling capacity is higher than the actual needs, thus causing a lot of unnecessary energy consumption.

[0059] Therefore, the embodiment of the present application provides a refrigeration control system 10, which operates a refrigeration strategy through the control module 13 of the refrigeration control system 10 and cooperates with the cold storage module 12 of the refrigeration control system 10 to cool down the working equipment 20, thereby reducing the switching frequency of the working state of the refrigeration control system 10, thereby reducing the operating energy consumption of the refrigeration control system 10. Figure 1, Figure 1 A schematic diagram of a refrigeration control system provided in an embodiment of the present application, wherein the refrigeration control system 10 may include: a refrigeration module 11, a cold storage module 12 and a control module 13; wherein the control module 13 is communicatively connected to the refrigeration module 11 and the cold storage module 12, respectively, so as to be able to send a control signal to the refrigeration module 11 or the cold storage module 12 to control the refrigeration module 11 or the cold storage module 12.

[0060] Exemplarily, the refrigeration module 11 is used to provide cold energy to cool the working equipment 20; the cold storage module 12 is used to cooperate with the refrigeration module 11 to cool based on the refrigeration requirements of the working equipment 20, or to store the cold energy released by the refrigeration module 11; the control module 13 is used to control the refrigeration module 11 and the cold storage module 12 to provide cold energy based on a first refrigeration strategy.

[0061] Specifically, please Figure 1 Based on the reference Figure 2 , Figure 2 This is a schematic diagram illustrating the principle of the refrigeration control system provided in an embodiment of the present application, applied to cooling of a working device. The working device 20 can be a single server or a server cluster consisting of multiple servers. The refrigeration module 11 can include an air-cooled refrigeration module 111 and a liquid-cooled refrigeration module 112. The number of air-cooled refrigeration modules 111 and liquid-cooled refrigeration modules 112 can be set based on the actual application scenario. In this embodiment of the present application, one air-cooled refrigeration module 111 and one liquid-cooled refrigeration module 112 are used for illustration.

[0062] The air-cooling module 111 may specifically include a condenser 1111 and an evaporator 1112. The evaporator 1112 removes heat from the server and delivers it to the condenser 1111 through a pipe, thereby releasing the server heat. The liquid-cooling module 112 may specifically include a refrigerated liquid distribution unit (CDU) 1121 and a liquid-cooled refrigeration air conditioner 1122. The refrigeration air conditioner in the liquid-cooling module 112 produces chilled water for the CDU 1121 and stores it in the CDU 1121. The chilled water is then delivered to the server cold plate liquid cooling components through pipes, removing heat from the cold plate liquid cooling components and thereby cooling the cold plate liquid cooling components.

[0063] The structural diagram of the cold storage module 12 can be found in Figure 3 , Figure 3The structural schematic diagram of the cold storage module provided in the embodiment of the present application, the cold storage module 12 may include: an air-cooled cold capacity inlet 121, an air-cooled cold capacity outlet 122, a cold storage medium 123, a liquid-cooled cold capacity inlet 124 and a liquid-cooled cold capacity outlet 125; the cold storage module 12 collects excess cold capacity of the air-cooled refrigeration module 111 and the liquid-cooled refrigeration module 112 through the air-cooled cold capacity inlet 121 and the liquid-cooled cold capacity inlet 124, respectively, and stores the cold capacity through the cold storage medium 123 to cooperate with the refrigeration module 11 to cool the working equipment 20.

[0064] The cold storage medium 123 may be a phase change material or water.

[0065] In the embodiment of the present application, taking the setting of multiple servers as an example, the multiple servers can be set in the cabinet 30, and the cold storage module 12 can be set next to the cabinet 30, thereby assisting the refrigeration module 11 to cool the servers.

[0066] Specifically, the first cooling strategy may include:

[0067] At a first moment, the refrigeration module 11 is controlled to release cooling capacity based on a first required cooling capacity; wherein the first required cooling capacity is determined based on the cooling capacity required by each of the working devices 20 and a cooling correction coefficient, or based on the cooling capacity required by each component of the working device 20 and the cooling correction coefficient.

[0068] The cooling capacity required by each working device 20 can be calculated by the monitoring module 14 of the refrigeration control system 10 based on the law of conservation of energy. The monitoring module 14 is respectively connected to the refrigeration module 11, the cold storage module 12, the control module 13, and the working device 20 to monitor the operating status of each module. For example, a single monitoring module 14 can simultaneously monitor the operating status of both the air-cooled refrigeration module 111 and the liquid-cooled refrigeration module 112. Alternatively, multiple monitoring modules 14 can be provided to separately monitor the operating status of each air-cooled refrigeration module 111 and the liquid-cooled refrigeration module 112, thereby making the control strategies independent of each other and operating more efficiently.

[0069] For the air-cooling refrigeration module 111, the formula W sn =cρq△T to obtain the air cooling capacity W required for a single server sn , where c is the specific heat capacity of air, ρ is the air density, q is the air flow rate passing through the server, and △T is the temperature difference between the inlet and outlet of the server.

[0070] For the liquid cooling module 112, the formula W can be used to calculate the yn =c y ρ y q y △T yGet the liquid cooling capacity W required for a single server yn , where c y is the specific heat capacity of the refrigerant liquid, ρ y is the density of the refrigeration liquid, q y is the flow rate of the refrigerant liquid, △T y is the temperature difference between the inlet and outlet of the liquid cooling component.

[0071] After obtaining the cooling capacity required by each server respectively, the cooling capacity required by the working equipment 20 can be determined by adding up the cooling capacities required by all servers and multiplying it by the cooling correction coefficient. The cooling correction coefficient can be mainly determined based on the length of the air-cooled or liquid-cooled cooling pipe, the server position and the error of the monitoring data. The determination method can be to obtain the historical data of the working equipment, and determine the influence of the cooling pipe length, the server position and the error of the monitoring data on the cooling capacity by simulating the historical data, thereby obtaining the value of the cooling correction coefficient.

[0072] In addition, when determining the cooling capacity required by the working equipment 20, the environmental impact and the cooling capacity required by other equipment may also be taken into consideration. The cooling capacity required by the working equipment 20 and the cooling capacity required by other equipment are combined to obtain the total required cooling capacity.

[0073] At a second moment, a second required cooling capacity of the working equipment 20 is obtained, and the second required cooling capacity is compared with the first required cooling capacity to obtain a comparison result; wherein the second moment is a moment after any interval of the first moment.

[0074] When the comparison result indicates that the second required cooling capacity is greater than the sum of the first required cooling capacity and the current cooling capacity of the cold storage device, the cooling module 11 is controlled to increase the cooling capacity.

[0075] When the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cold storage device reaches the maximum cooling capacity, the cooling module 11 is controlled to reduce the cooling capacity.

[0076] It should be noted that the above-mentioned first moment and second moment are not unique. During the operation of the working equipment, the above-mentioned control strategy can be repeatedly executed periodically or multiple times according to demand. After a second moment, the second moment can be used to represent a moment when the working equipment is working, and the second moment in the previous control strategy can be used as the first moment in this control strategy.

[0077] It can be seen that the refrigeration control system provided in the embodiment of the present application can cool down the working equipment based on the formulated refrigeration strategy, and control the working condition changes of the refrigeration module only in two cases: when the increase in the server's cooling demand is greater than the current cooling capacity of the cold storage module, or when the server's cooling demand decreases and the cooling capacity stored in the cold storage module reaches the maximum. This can reduce the switching frequency of the working state of the refrigeration control system, thereby reducing the operating energy consumption of the refrigeration control system.

[0078] In an optional embodiment, the first cooling strategy may further include:

[0079] When the comparison result indicates that the second required cooling capacity is greater than the first required cooling capacity and less than the sum of the first required cooling capacity and the current cooling capacity of the cooling storage device, the cooling storage module 12 is configured to provide cooling capacity; or

[0080] When the comparison result indicates that the second required cooling capacity is equal to the first required cooling capacity, the refrigeration module 11 is configured to maintain the same working state as at the first moment, and the cold storage module 12 is configured to be in an idle state of stopping working; or

[0081] When the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cold storage device has not reached the maximum cooling capacity, the refrigeration module 11 is configured to maintain the same working state as the first moment, and the cold storage module 12 is configured to a working state of storing cooling capacity.

[0082] It can be seen that the refrigeration control system provided in the embodiment of the present application can cool down the working equipment based on the formulated refrigeration strategy. When the increase in the server's cooling demand is greater than the cooling capacity of the current cold storage module, or when the server's cooling demand decreases and the cooling capacity stored in the cold storage module reaches the maximum, the cold storage module is used to participate in the cooling control of the server, ensuring that the refrigeration module maintains the original working condition for a longer period of time, reducing the switching frequency of the working state of the refrigeration control system, and realizing peak shaving and valley filling of energy consumption, thereby reducing the operating energy consumption of the refrigeration control system and extending the working life of the refrigeration module.

[0083] Optionally, the control strategy provided in the embodiment of the present application can also be optimized according to the actual operating conditions of the refrigeration control system 10. A cold storage module cold capacity safety factor can be added thereto, and the cold capacity that the cold storage module 12 can safely provide can be determined based on the cold storage module cold capacity safety factor, thereby improving the control accuracy and the safety of the refrigeration control system 10.

[0084] The control module 13 may also be used to:

[0085] The cold capacity that the cold storage module 12 can provide is determined based on the safety factor of the cold storage device; wherein the cold capacity that the cold storage module 12 can provide is equal to the product of the safety factor and the current cold storage capacity of the cold storage device; and the refrigeration module 11 and the cold storage module 12 are controlled to provide cold capacity based on the second refrigeration strategy.

[0086] The second strategy is obtained by combining the first strategy and the safety factor of the cold storage module 12. The second refrigeration strategy may include:

[0087] At a first moment, the refrigeration module 11 is controlled to release cooling capacity based on a first required cooling capacity; wherein the first required cooling capacity is determined based on the cooling capacity required by each of the working devices 20 and a cooling correction coefficient, or based on the cooling capacity required by each component of the working device 20 and the cooling correction coefficient.

[0088] At a second moment, a second required cooling capacity of the working equipment 20 is obtained, and the second required cooling capacity is compared with the first required cooling capacity to obtain a comparison result; wherein the second moment is a moment after any interval of the first moment.

[0089] When the comparison result indicates that the second required cooling capacity is greater than the sum of the first required cooling capacity and the cooling capacity that can currently be provided by the cold storage device, the cooling module 11 is controlled to increase the cooling capacity.

[0090] When the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cold storage device reaches the maximum cooling capacity, the cooling module 11 is controlled to reduce the cooling capacity.

[0091] For example, continue with Figure 2 The control strategy of the control module 13 may specifically include:

[0092] According to the formula W=k(W s1(t) +W s2(t) +W s3(t) +…+W sn(t) )+W h as well as

[0093] W y =k y (W y1(t) +W y2(t) +W y3(t) +…+W yn(t) )+W h Determine the first required cooling capacity of the server at the first moment, where W is the cooling capacity provided by the air cooling module 111, and W yThe cooling capacity provided for the liquid cooling refrigeration module 112, where k is the refrigeration correction coefficient, W s1(t) to W sn(t) and W y1(t) to W yn(t) The air-cooling or liquid-cooling capacity required for each server, W h The cooling capacity required due to environmental impact or other equipment.

[0094] Determine the second required cooling capacity of the server at the second moment again in the above manner, and compare it with the first required cooling capacity. When the second required cooling capacity is less than the first required cooling capacity, continue to compare whether the cooling capacity Wc(t) of the current cold storage module 12 is the maximum cooling capacity Wc(MAX). If Wc(t) < Wc(MAX), that is, the cooling capacity of the current cold storage module 12 has not reached the maximum cooling capacity, control the air-cooling inlet 121 and liquid-cooling inlet 124 of the cold storage module 12 to open, and the air-cooling outlet 122 and liquid-cooling outlet 125 to close, so that the cold storage module 12 starts to store cold. At this time, the refrigeration module 11 continues to operate under the original working conditions. If Wc(t) = Wc(MAX), that is, the cooling capacity Wc(t) of the current cold storage module 12 reaches the maximum cooling capacity Wc(MAX), control the cold storage module 12 not to work, and the refrigeration module 11 continues to operate under the original working conditions.

[0095] If the second required cooling capacity is equal to the first required cooling capacity, control the cold storage module 12 not to work at this time, and the refrigeration module 11 continues to operate under the original working conditions.

[0096] If the second required cooling capacity is greater than the first required cooling capacity, calculate and judge the difference between Wn(t) - Wn(t - 1) and m * Wc(t), where Wn(t) is the second required cooling capacity, Wn(t - 1) is the first required cooling capacity, m is the cold storage module cooling capacity safety factor, and the value of this coefficient is between 0 and 1, and Wc(t) represents the cooling capacity of the current cold storage module.

[0097] If Wsn(t) - Wsn(t - 1) < m * Wc(t), that is, the increased cooling capacity demand of the server is less than m times the cooling capacity of the current cold storage module. At this time, the air-cooling inlet 121 and liquid-cooling inlet 124 of the cold storage module 12 are closed, and the air-cooling outlet 122 and liquid-cooling outlet 125 are opened. The cold storage module 12 starts to provide the increased cooling capacity demand for the server, and the refrigeration module 11 continues to operate under the original working conditions.

[0098] If Wsn(t) - Wsn(t-1) ≥ m*Wc(t), the server's increased cooling demand is greater than or equal to m times the cooling capacity of the current cold storage module. At this point, the air cooling inlet 121 and liquid cooling inlet 124 of the cold storage module 12 are closed, while the air cooling outlet 122 and liquid cooling outlet 125 are opened. Meanwhile, the cooling capacity of the refrigeration module 11 is increased. Together, the cold storage module 12 and refrigeration module 11 provide the air cooling capacity required by the server.

[0099] It should be understood that in the above implementation process, the air-cooled refrigeration module 111 and the liquid-cooled refrigeration module 112 are controlled simultaneously. In actual application, the air-cooled refrigeration module 111 and the liquid-cooled refrigeration module 112 can also be controlled separately. The method of separate control is consistent with the above implementation process and will not be repeated here.

[0100] It can be seen from this that the embodiment of the present application can determine the amount of cold that the cold storage module can safely provide based on the safety factor of the cold storage module, and based on this, realize the control of the working state of the cold storage module, so as to cooperate with the refrigeration module to cool the working equipment in a safe state, which can improve the control accuracy and safety of the refrigeration control system.

[0101] Based on the same inventive concept, the present application also provides a refrigeration control method. Figure 4 , Figure 4 This is a schematic diagram of the steps of the refrigeration control method provided in an embodiment of the present application. The refrigeration control method can be applied to the refrigeration control system provided in the above implementation. The steps of the method may include:

[0102] In step S41, the control module controls the refrigeration module to release cooling capacity based on a first required cooling capacity at a first moment.

[0103] The first required cooling capacity is determined based on the cooling capacity required by each of the working devices and a cooling correction factor, or based on the cooling capacity required by each component of the working device and the cooling correction factor.

[0104] In step S42, a second required cooling capacity of the working equipment is obtained at a second moment, and the second required cooling capacity is compared with the first required cooling capacity to obtain a comparison result.

[0105] The second moment is a moment after any interval of the first moment. The first moment and the second moment are not unique. During the operation of the working device, the above control strategy can be repeatedly executed periodically or multiple times as needed. After a second moment, another second moment can be used to represent a moment in the operation of the working device, and the second moment in the previous control strategy is used as the first moment in this control strategy.

[0106] In step S43, when the comparison result indicates that the second required cooling capacity is greater than the sum of the first required cooling capacity and the current cooling capacity of the cold storage device, the control module controls the cooling module to increase the cooling capacity.

[0107] In step S44, when the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cold storage device reaches the maximum cooling capacity, the control module controls the cooling module to reduce the cooling capacity.

[0108] The implementation of controlling the refrigeration control system by the above method can be specifically referred to the workflow of the above refrigeration control system, which will not be described in detail here.

[0109] It can be seen from this that the embodiment of the present application can control the operating condition changes of the refrigeration module only in two cases: when the increase in the server's cooling demand is greater than the current cooling capacity of the cold storage module, or when the server's cooling demand decreases and the cooling capacity stored in the cold storage module reaches the maximum. This can reduce the switching frequency of the working state of the refrigeration control system, thereby reducing the operating energy consumption of the refrigeration control system.

[0110] Optionally, the refrigeration control method may further include the following steps based on the above steps:

[0111] When the comparison result indicates that the second required cooling capacity is greater than the first required cooling capacity and less than the sum of the first required cooling capacity and the current cooling capacity of the cooling storage device, the control module controls the cooling storage module to provide cooling capacity.

[0112] Or when the comparison result indicates that the second required cooling capacity is equal to the first required cooling capacity, the control module controls the refrigeration module to maintain the same working state as at the first moment, and controls the cold storage module to be in an idle state of stopping working.

[0113] Or when the comparison result indicates that the second required cooling capacity is less than the first required cooling capacity and the current cooling capacity of the cold storage device has not reached the maximum cooling capacity, the control module controls the refrigeration module to maintain the same working state as the first moment, and controls the cold storage module to store cold capacity.

[0114] It can be seen from this that the embodiment of the present application can also use the cold storage module to participate in the cooling control of the server when the increase in the server's cooling demand is greater than the cooling capacity of the current cold storage module, or when the server's cooling demand decreases and the cooling capacity stored in the cold storage module reaches the maximum. This ensures that the cooling module maintains the original operating conditions for a longer period of time, reduces the switching frequency of the working state of the cooling control system, and achieves peak shaving and valley filling of energy consumption, thereby reducing the operating energy consumption of the cooling control system and extending the working life of the cooling module.

[0115] In an optional embodiment, after step S42, the present application embodiment also provides an implementation method for refrigeration control in combination with the safety factor of the cold storage equipment, see Figure 5 , Figure 5 A schematic diagram of the steps for performing refrigeration control in combination with the safety factor of the cold storage equipment provided in an embodiment of the present application may include:

[0116] In step S51, the cooling capacity that can be provided by the cold storage module is determined based on the safety factor of the cold storage device.

[0117] The cold storage capacity that can be provided by the cold storage module is equal to the product of the safety factor and the current cold storage capacity of the cold storage device.

[0118] In step S52, when the comparison result indicates that the second required cooling capacity is greater than the sum of the first required cooling capacity and the cooling capacity currently provided by the cold storage device, the control module controls the refrigeration module to increase the cooling capacity.

[0119] It can be seen from this that the embodiment of the present application can determine the amount of cold that the cold storage module can safely provide based on the safety factor of the cold storage module, and based on this, realize the control of the working state of the cold storage module, so as to cooperate with the refrigeration module to cool the working equipment in a safe state, which can improve the control accuracy and safety of the refrigeration control system.
