Description

Technical Field

[0001] This application relates to the field of information security technology, and more specifically, to a control method and device, storage medium and electronic equipment for a precision air conditioner in a computer room. Background Technology

[0002] Currently, data center cooling systems typically use precision air conditioners to cool the server room. Due to the large heat dissipation in server rooms, multiple precision air conditioners are usually required. To ensure reliability, backup units are also deployed to cool the server room during equipment failures or maintenance. Furthermore, because server racks are arranged in rows, and the rack sizes and power consumption vary, the distribution of equipment and heat dissipation within the server room is uneven. Precision air conditioner manufacturers cannot access this information regarding equipment deployment and power consumption. Therefore, related technologies often only adjust the supply and return air temperatures, and to simplify operation, all units are adjusted identically, simply by adjusting fan speeds. Additionally, backup units are often deactivated based on the server rack configuration, without considering the overall power consumption of the server racks. This can lead to backup units being located in areas with high data volume and power consumption, potentially causing localized hotspots and compromising the safe and stable operation of the server room. Therefore, it is difficult to reasonably control the operation of precision air conditioners in computer rooms using related technologies, which can lead to poor performance of precision air conditioners in computer rooms. For example, it can result in low cooling efficiency, high operating costs of the cooling system, and the potential for localized hot spots in the computer room, making it difficult to ensure the safe and reliable operation of the computer room.

[0033] For ease of description, the following explains some of the nouns or terms used in the embodiments of this application:

[0034] Precision air conditioning for computer rooms: These are specialized air conditioners designed for modern electronic equipment rooms. Their working precision and reliability are much higher than those of ordinary air conditioners.

[0035] The present invention will now be described in conjunction with preferred implementation steps. Figure 1 This is a flowchart of a control method for a precision air conditioner in a computer room according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps:

[0036] Step S101: Determine N cold aisles and N precision air conditioners in the target computer room, wherein the cold aisles are located between every two server racks in the target computer room, and N is a positive integer.

[0037] For example, multiple server racks and multiple precision air conditioners (N precision air conditioners) can be deployed in the computer room (the target computer room mentioned above). Furthermore, when deploying these devices in the computer room, to increase the supply and return air temperature difference, the server racks are generally deployed face-to-face and back-to-back, with cold aisles. Cold air enters the cold aisle from the floor supply air and then serves the racks on both sides; that is, one cold aisle serves two racks. Therefore, considering the racks within a single cold aisle as a whole, we can uniformly represent the relevant information of rack 1 and rack 2 as Cold Aisle 1 for the control of the precision air conditioners. In addition, precision air conditioners generally adopt a K+1 deployment method, that is, K units are in operation, and 1 unit is a standby unit. When a precision air conditioner fails or requires maintenance, the standby unit is activated.

[0038] Step S102: Obtain the first location information of each cold aisle, the second location information of each precision air conditioner in the computer room, the power information of each cold aisle, and the current operating parameter set, wherein the current operating parameter set includes at least the current operating parameters of each of the N precision air conditioners in the computer room.

[0039] For example, the control system can first receive the cold aisle location (the first location information mentioned above) and power information f(s, p), as well as the location of the precision air conditioner (the second location information mentioned above) and various operating parameters (the current set of operating parameters mentioned above).

[0040] Step S103: Based on the first position information of each cold aisle, the second position information of each precision air conditioner in the computer room, and the power information of each cold aisle, determine the M precision air conditioners that need to be operated from the N precision air conditioners in the computer room, where M is a positive integer and M is less than or equal to N.

[0041] For example, the control system can determine the priority order of precision air conditioners serving the cold aisle based on the cold aisle location information f(s) and the precision air conditioner location information. Then, based on the cold aisle power information f(p) and the priority order of the precision air conditioners serving the cold aisle, it can determine which precision air conditioners (the aforementioned M precision air conditioners) need to operate in the computer room. For instance, if there are 5 precision air conditioners in the computer room, by using the cold aisle location information f(s), the precision air conditioner location information, and the cold aisle power information f(p), it can determine that the first three of the 5 precision air conditioners need to operate.

[0042] Step S104: Based on the current set of operating parameters, adjust the operating parameters of the M precision air conditioners in the computer room to obtain a target set of operating parameters, and control the operation of the M precision air conditioners in the computer room based on the target set of operating parameters. The target set of operating parameters includes at least the target operating parameters of each of the M precision air conditioners in the computer room.

[0043] For example, the control system can obtain the current operating parameters of the precision air conditioner to be operated from the previously acquired operating parameters of the precision air conditioner in the computer room (the aforementioned set of current operating parameters), adjust the operating parameters of the precision air conditioner to be operated, and after adjusting the parameters, make the precision air conditioner to be operated operate with the adjusted parameters (the aforementioned target operating parameters).

[0044] It should be noted that the control method for precision air conditioning in computer rooms provided in this application embodiment can be applied to financial scenarios.

[0045] Through the steps S101 to S104 described above, the operating parameters of the precision air conditioners in the computer room are adjusted based on the location and power information of each cold aisle in the computer room, as well as the location information of each precision air conditioner in the computer room. This yields the optimal operating parameters for the precision air conditioners, allowing them to operate more efficiently. This, in turn, improves cooling efficiency and reduces the operating costs of the cooling system. It also reduces the occurrence of local hot spots in the computer room, thereby ensuring the safe and reliable operation of the computer room.

[0046] Optionally, in the control method for precision air conditioners in a data center provided in this application embodiment, determining the M precision air conditioners that need to be operated from N precision air conditioners based on the first location information of each cold aisle, the second location information of each precision air conditioner, and the power information of each cold aisle includes: determining the priority order of the N precision air conditioners when they provide services to the cold aisles based on the first location information of each cold aisle and the second location information of each precision air conditioner; obtaining the maximum cooling capacity of each precision air conditioner among the N precision air conditioners; determining the number of precision air conditioners that need to be operated based on the maximum cooling capacity of each precision air conditioner and the power information of each cold aisle; and determining the M precision air conditioners from the N precision air conditioners based on the priority order and the number of precision air conditioners that need to be operated.

[0047] For example, the control system can determine the priority order of precision air conditioners serving the cold aisle based on the location information f(s) of the cold aisle and the location information of the precision air conditioners. For example, the priority order of precision air conditioners serving or adjusting cold aisle 1 is precision air conditioner 1 > precision air conditioner 2 > precision air conditioner 3 > precision air conditioner 4 > precision air conditioner 5, and the priority order of precision air conditioners serving or adjusting cold aisle 2 is precision air conditioner 2 > precision air conditioner 1 > precision air conditioner 3 > precision air conditioner 4 > precision air conditioner 5.

[0048] Then, the control system can compare the power information f(p) of the cold aisle with the maximum cooling capacity of a single precision air conditioner to determine the number of precision air conditioners that need to be operated. Based on the required number of precision air conditioners and their priority order for serving the cold aisle, the system selects the necessary precision air conditioners from the total number of precision air conditioners in the computer room. For example, if it is determined that 3 precision air conditioners need to be operated, and the priority order for serving or adjusting cold aisle 1 is Precision Air Conditioner 1 > Precision Air Conditioner 2 > Precision Air Conditioner 3 > Precision Air Conditioner 4 > Precision Air Conditioner 5, then it can be determined that of the total 5 precision air conditioners in the computer room, Precision Air Conditioner 1, Precision Air Conditioner 2, and Precision Air Conditioner 3 need to be operated.

[0049] Using the above method, based on the location information of the cold aisle, the location information of the precision air conditioner, and the power information of the cold aisle, the precision air conditioner that needs to be operated in the computer room can be quickly and accurately determined.

[0050] Optionally, in the control method for precision air conditioners in a computer room provided in this application embodiment, adjusting the operating parameters of M precision air conditioners based on the current set of operating parameters to obtain a target set of operating parameters includes: determining a first precision air conditioner and T second precision air conditioners from the M precision air conditioners, wherein the first precision air conditioner is the last precision air conditioner in the M precision air conditioners that provides services for the cold aisle, and the second precision air conditioner is the precision air conditioner in the M precision air conditioners other than the first precision air conditioner, where T is a positive integer and T is less than M; determining the current operating parameters of the first precision air conditioner and the current operating parameters of the T second precision air conditioners based on the current set of operating parameters; adjusting the current operating parameters of the first precision air conditioner to the target operating parameters; adjusting the current operating parameters of the T second precision air conditioners to the rated operating parameters; and obtaining the target set of operating parameters based on the target operating parameters and the rated operating parameters.

[0051] For example, after identifying the precision air conditioners that need to operate in the computer room, the last precision air conditioner to be running (the aforementioned first computer room precision air conditioner) can be determined. For instance, if it is determined that there are 3 precision air conditioners that need to operate, and the priority order for precision air conditioners serving or adjusting cold aisle 1 is precision air conditioner 1 > precision air conditioner 2 > precision air conditioner 3 > precision air conditioner 4 > precision air conditioner 5, then it can be determined that of the total 5 precision air conditioners in the computer room, precision air conditioner 1, precision air conditioner 2, and precision air conditioner 3 need to operate, and the operating order of these 3 precision air conditioners is precision air conditioner 1 > precision air conditioner 2 > precision air conditioner 3. Therefore, precision air conditioner 3 can be designated as the aforementioned first computer room precision air conditioner, and precision air conditioners 1 and 2 can be designated as the aforementioned T-type second computer room precision air conditioner. Then, the operating parameters of each of the three precision air conditioners (precision air conditioner 1, precision air conditioner 2, and precision air conditioner 3) can be obtained from the previously acquired operating parameters of the precision air conditioners in the computer room. The operating parameters of precision air conditioner 3 are then adjusted to the optimal operating parameters, and the operating parameters of precision air conditioner 1 and precision air conditioner 2 are adjusted to the rated operating parameters of each precision air conditioner. Finally, the optimal operating parameters of precision air conditioner 3 and the rated operating parameters of precision air conditioner 1 and precision air conditioner 2 are summarized into the target operating parameter set mentioned above.

[0052] The above method allows for quick and accurate adjustment of the parameters of the precision air conditioners that need to operate in the computer room.

[0053] Optionally, in the control method for a precision air conditioner in a computer room provided in this application embodiment, adjusting the current operating parameters of the first precision air conditioner in the computer room to the target operating parameters includes: obtaining the first cooling capacity allocated to the first precision air conditioner in the computer room; determining the first physical model of the first precision air conditioner in the computer room; determining the target operating parameters based on the first cooling capacity and the first physical model; and adjusting the current operating parameters of the first precision air conditioner in the computer room to the target operating parameters.

[0054] For example, the control system can first calculate the cooling capacity of the last operating precision air conditioner (the aforementioned first cooling capacity), and then obtain the specific physical model of the precision air conditioner (the aforementioned first physical model). Based on the calculated cooling capacity of the last operating precision air conditioner and the specific physical model of the precision air conditioner, a genetic algorithm is used to calculate the optimal operating parameters (the aforementioned target operating parameters) of the last precision air conditioner among those that need to be operated, and the operating parameters of the last precision air conditioner among those that need to be operated are adjusted to the calculated optimal operating parameters.

[0055] Using the above method, the optimal operating parameters for the last precision air conditioner that needs to be running in the computer room can be calculated quickly and accurately.

[0056] Optionally, in the control method for a precision air conditioner in a computer room provided in this application embodiment, obtaining the first cooling capacity allocated to the first precision air conditioner in the computer room includes: obtaining the second cooling capacity to be allocated; determining an allocation strategy for allocating cooling capacity to M precision air conditioners in the computer room; and determining the first cooling capacity allocated to the first precision air conditioner in the computer room based on the allocation strategy and the second cooling capacity to be allocated.

[0057] For example, the control system can first compare the power information f(p) with the maximum cooling capacity of a single precision air conditioner to determine the number of precision air conditioners that need to be operated. Then, based on the number of operating precision air conditioners, the cooling capacity allocation for each precision air conditioner is obtained. Following the strategy of operating one at full capacity before operating another, the cooling capacity of the last operating precision air conditioner is calculated.

[0058] Using the above method, the cooling capacity of the last precision air conditioner that needs to be running in the computer room can be calculated quickly and accurately.

[0059] Optionally, in the control method for a precision air conditioner in a computer room provided in this application embodiment, determining the first physical model of the first precision air conditioner in the computer room includes: obtaining the operating mechanism of the precision air conditioner in the computer room; determining the second physical model of the precision air conditioner in the computer room based on the operating mechanism of the precision air conditioner in the computer room; and determining the first physical model of the first precision air conditioner in the computer room based on the second physical model.

[0060] For example, the control system can obtain the physical model of the precision air conditioner (the second physical model mentioned above) based on the operating mechanism of the precision air conditioner, where P = f (required cooling capacity Q, fan speed r, chilled water supply temperature t, and supply air temperature t). Then, based on the physical model of the precision air conditioner, the specific physical model of the precision air conditioner (the first physical model mentioned above) can be obtained.

[0061] Based on the operating mechanism of precision air conditioners, the physical model of precision air conditioners can be determined quickly and accurately using the above method.

[0062] Optionally, in the control method for a precision air conditioner in a computer room provided in this application embodiment, determining the first physical model of the precision air conditioner in the first computer room based on the second physical model includes: acquiring historical operating data of the precision air conditioner in the first computer room; and using a model identification algorithm to identify the second physical model based on the historical operating data of the precision air conditioner in the first computer room to obtain the first physical model of the precision air conditioner in the first computer room.

[0063] For example, after obtaining the physical model of the precision air conditioner (the second physical model mentioned above), P = f (required cooling capacity Q, fan speed r, chilled water supply temperature t, and supply air temperature t), the physical model of the precision air conditioner (the second physical model mentioned above) can be analyzed based on the precise historical operating data and through an adaptive online model identification algorithm to obtain the specific physical model P of the precision air conditioner (the first physical model mentioned above).

[0064] Using the above method, based on the physical model of the precision air conditioner, the specific physical model of the last precision air conditioner that needs to be operated in the computer room can be quickly and accurately determined.

[0065] The method provided in this application embodiment, for example, can integrate the location information and real-time power information of server racks in a data center with the operation control of the precision air conditioner in the data center into a unified control platform. The operation control of the precision air conditioner is combined with the location and power information of the server racks within the data center to jointly achieve energy-efficient and optimized operation of the precision air conditioner. Simultaneously, a physical model of the precision air conditioner is obtained based on its operating mechanism. Combined with historical operating data, a specific physical model is obtained. Based on the rack power information, the physical model is analyzed using optimization methods to obtain the optimal operating parameters of the precision air conditioner, further reducing its energy consumption. Furthermore, the precision air conditioner energy-saving control strategy can reduce the occurrence of local hotspots in the data center, optimize airflow organization, and optimize the operation of the precision air conditioner, thereby reducing operating costs.

[0066] For example, Figure 2 This is a schematic diagram illustrating the arrangement of server racks and precision air conditioning equipment in an embodiment of this application, as shown below. Figure 2As shown, to improve the supply and return air temperature difference, server racks are generally deployed face-to-face and back-to-back, with cold aisles. Cold air enters the cold aisle from the floor supply air and then serves the racks on both sides. That is, one cold aisle serves two racks. Therefore, the racks within a single cold aisle are considered as a whole, and the relevant information for rack 1 and rack 2 is uniformly represented by Cold Aisle 1 for the control of precision air conditioning. Precision air conditioning systems generally use a K+1 deployment method, meaning K units are in operation and one unit is a standby unit. The standby unit operates when the precision air conditioning system fails or requires maintenance.

[0067] For example, Figure 3 This is a schematic diagram illustrating the energy-saving control principle of precision air conditioning in the embodiments of this application, such as... Figure 3 As shown, cold aisle 1 f(s, p) can represent the position and power information of cabinet 1 and cabinet 2, cold aisle 2 f(s, p) can represent the position and power information of cabinet 3 and cabinet 4, and so on.

Based on the cold aisle position information f(s), the control system compares it with the position information of the precision air conditioners to determine the priority order of the precision air conditioners serving the cold aisles. Based on the cold aisle power information f(p), the control system adjusts the operating parameters of the precision air conditioners in sequence, and obtains the optimal operating parameters of the precision air conditioners based on the physical model and genetic algorithm of the precision air conditioners.

[0068] For example, Figure 4 This is a flowchart of an optional control method for a precision air conditioner in a computer room, provided according to an embodiment of this application. Figure 4 As shown, the optional control method for a precision air conditioner in a computer room may include the following steps:

[0069] (1) First, the control system receives the cold aisle location and power information f(s, p), as well as the location and various operating parameters of the precision air conditioner.

[0070] (2) The control system determines the priority order of precision air conditioners serving the cold aisle based on the location information f(s) of the cold aisle and the location information of the precision air conditioners. For example, the priority order of precision air conditioners serving or adjusting cold aisle 1 is precision air conditioner 1>precision air conditioner 2>precision air conditioner 3>precision air conditioner 4>precision air conditioner 5, and the priority order of precision air conditioners serving or adjusting cold aisle 2 is precision air conditioner 2>precision air conditioner 1>precision air conditioner 3>precision air conditioner 4>precision air conditioner 5.

[0072] A) First, based on the power information f(p), compare it with the maximum cooling capacity of a single precision air conditioner to determine the number of precision air conditioners that need to be operated. Based on the number of operating units, obtain the cooling capacity allocation for each precision air conditioner. Following the strategy of operating one unit at full capacity before starting another, calculate the cooling capacity of the last operating precision air conditioner.

[0073] B) Based on the operating mechanism of precision air conditioning, a physical model of the precision air conditioning is obtained, P = f(required cooling capacity Q, fan speed r, chilled water supply temperature t, and supply air temperature t). Based on historical operating data of the precision air conditioning system, a specific physical model P is obtained through an adaptive online model identification algorithm.

[0074] C) Based on the calculated cooling capacity of the last operating precision air conditioner and the specific physical model P of the precision air conditioner, the optimal operating parameters (fan speed r, chilled water supply temperature t, and air supply temperature t) of the precision air conditioner are calculated using a genetic algorithm to minimize the energy consumption of the precision air conditioner.

[0075] Therefore, the energy-saving optimization control strategy for precision air conditioning in computer rooms provided in this application embodiment can make the operation of precision air conditioning more reasonable, improve cooling efficiency, reduce the operating cost of the cooling system, and ensure the safe and reliable operation of the computer room. In addition, the energy-saving control strategy for precision air conditioning provided in this application embodiment can reduce the occurrence of local hot spots in the computer room, optimize airflow organization, and optimize the operation of the precision air conditioning, thereby reducing operating costs.

[0076] In summary, the control method for precision air conditioners in a data center provided in this application determines N cold aisles and N precision air conditioners in a target data center, wherein the cold aisles are located between every two server racks in the target data center, and N is a positive integer; it acquires first position information of each cold aisle, second position information of each precision air conditioner, power information of each cold aisle, and a set of current operating parameters, wherein the set of current operating parameters includes at least the current operating parameters of each of the N precision air conditioners; and it controls the air conditioners based on the first position information of each cold aisle, the second position information of each precision air conditioner, and the power information of each cold aisle. The power information of the cold aisle is used to determine the M precision air conditioners that need to operate from N precision air conditioners in the computer room, where M is a positive integer and M is less than or equal to N. Based on the current set of operating parameters, the operating parameters of the M precision air conditioners are adjusted to obtain a target set of operating parameters. The operation of the M precision air conditioners is then controlled based on this target set of operating parameters. This target set of operating parameters includes at least the target operating parameters for each of the M precision air conditioners.

By adjusting the operating parameters of the precision air conditioners based on the location and power information of each cold aisle in the computer room, as well as the location information of each precision air conditioner, the optimal operating parameters are obtained. The precision air conditioners operate according to these optimal parameters, resulting in more rational operation, improved cooling efficiency, reduced operating costs of the cooling system, and reduced hot spots in the computer room, thus ensuring the safe and reliable operation of the computer room.
