[0047] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0049] Figure 1 is a block diagram showing an air conditioning control system of a data center according to an exemplary embodiment. Figure 2 is a structural diagram of an air conditioning control system for a data center according to an exemplary embodiment. Figure 3 is a structural diagram of another air conditioning control system for a data center according to an exemplary embodiment, Figure 1-Figure 3 The air conditioning control system 100 of the data center includes: a monitoring device 110 and a controller 120.

[0050] The monitoring device 110 is connected to the air-conditioning system 200 and is configured to monitor the water consumption of the air-conditioning system 200, which is the total water consumption of each air-conditioning unit in the air-conditioning system 200 within a set time. The controller 120 is connected to the air-conditioning system 200 and the monitoring device 110 respectively, and is configured to obtain the total water consumption of the air-conditioning system 200 within a set time, and determine whether the air-conditioning system 200 meets the first working mode switching condition based on the total water consumption. If it is determined that the air-conditioning system 200 meets the first working mode switching condition, a first working mode switching instruction is generated, wherein the first working mode switching instruction is used to instruct the air-conditioning system 200 to switch to the water-saving working mode.

[0051] Specifically, combined Figure 2 and Figure 3As shown, the air-conditioning system 200 includes at least one air-conditioning unit, and a corresponding electric valve V1-n is set at the water inlet of each air-conditioning unit. For example, an electric valve V1-1 is set at the water inlet of the first air-conditioning unit, an electric valve V1-2 is set at the water inlet of the second air-conditioning unit, and an electric valve V1-n is set at the water inlet of the nth air-conditioning unit. In addition, a water meter is set at the water inlet and the water outlet of each air-conditioning unit to respectively obtain the amount of water flowing into and out of the air-conditioning unit. For example, water meter FM1-1 is set at the water inlet of the first air-conditioning unit, and water meter FM2-1 is set at the water outlet; water meter FM1-2 is set at the water inlet of the second air-conditioning unit, and water meter FM2-2 is set at the water outlet; water meter FM1-3 is set at the water inlet of the second air-conditioning unit, and water meter FM2-3 is set at the water outlet; water meter FM1-n is set at the water inlet of the nth air-conditioning unit, and water meter FM2-n is set at the water outlet.

[0052] The monitoring device 110 can monitor the water meters at the water inlet and outlet of each air-conditioning unit, and calculate the water consumption of each air-conditioning unit within a set time, such as subtracting the value of the water meter at the water inlet from the value of the water meter at the water outlet to obtain the water consumption of each air-conditioning unit within the set time, and then calculate the water consumption of the air-conditioning system 200 according to the water consumption of each air-conditioning unit within the set time, such as adding the water consumption of each air-conditioning unit within the set time to obtain the total water consumption of the air-conditioning system 200 within the set time. Among them, the operation and maintenance personnel can input the set time through the human-computer interaction interface of the air-conditioning system 200, such as inputting 0 o'clock to 24 o'clock.

[0053] After obtaining the total water consumption within the set time period, the controller 120 determines whether the air-conditioning system 200 meets the first working mode switching conditions, such as determining the relationship between the total water consumption and the first preset water supply upper limit. If the total water consumption reaches the first preset water supply upper limit, it is determined that the air-conditioning system 200 meets the first working mode switching conditions. At this time, the first working mode switching instruction is generated to switch the air-conditioning system 200 to the water-saving working mode.

[0054] The operation and maintenance personnel can input the capacity of the water reservoir, the capacity of the water tank, and the model of each air-conditioning unit through the human-computer interaction interface, so that the controller 120 can calculate the first preset upper limit of water supply. It should be noted that the first preset upper limit of water supply can be set according to the theoretical calculation value first, or it can be adjusted according to the operation and maintenance strategy after accumulating certain operation and maintenance data.

[0055] As a feasible approach, Figure 2 and 3As shown, the above-mentioned air-conditioning control system 100 includes: an electric valve V1, which is arranged on the water supply pipeline of the air-conditioning system 200. The first working mode switching instruction includes a closing instruction of the electric valve. When the closing instruction is triggered, the electric valve V1 disconnects the water supply of the water supply pipeline.

[0056] That is to say, when the total water consumption reaches the first preset water supply upper limit, a first working mode switching instruction is generated and sent to the electric valve V1 to control the electric valve V1 to close, disconnect the water supply of the water supply pipeline, and link the water supply pump to stop running. At the same time, it is sent to the compressor to control the compressor to start running, that is, to switch the air-conditioning system 200 to the water-saving working mode.

[0057] The air conditioning control system of the data center provided by the embodiment of the present disclosure monitors the water consumption of the air conditioning system through a monitoring device, and the water consumption is the total water consumption of each air conditioning unit in the air conditioning system within a set time. The total water consumption of the air conditioning system within the set time is obtained through a controller, and whether the air conditioning system meets the first working mode switching condition is judged based on the total water consumption. If it is judged that the air conditioning system meets the first working mode switching condition, a first working mode switching instruction for instructing the air conditioning system to switch to the water-saving working mode is generated. Therefore, the system can take into account both water-saving performance and power-saving performance while ensuring sufficient air conditioning cooling capacity, and is easy to implement.

[0058] As an implementable manner, the air conditioning control system 100 includes: a spray device (not shown in the figure), which is connected to the air conditioning system 200. The controller 120 is further configured to determine whether the air conditioning system 200 meets the spray condition based on the total water consumption, and if it is determined that the air conditioning system 200 meets the spray condition, generate a spray instruction, which is used to instruct the air conditioning system 200 to start the spray device.

[0059] Specifically, after obtaining the total water consumption within the set time period, the controller 120 determines whether the air-conditioning system 200 meets the spraying conditions, such as determining the relationship between the total water consumption and the first preset water supply upper limit. If the total water consumption does not reach the first preset water supply upper limit, it is determined that the air-conditioning system 200 meets the spraying conditions. At this time, a spray instruction is generated to control the air-conditioning system 200 to start the spray device.

[0060] To ensure that the water in the water tank can meet the preset time (such as 12 hours) of full load operation of the air conditioning system 200, Figure 2 and Figure 3As shown, the above-mentioned air-conditioning control system 100 also includes: a water storage pump, which is arranged on the pipeline between the water reservoir and the water tank of the air-conditioning system 200; the controller 120 is also configured to detect whether the water level in the water tank is lower than the predetermined water level, and if the water level in the water tank is lower than the predetermined water level, a water replenishment instruction is generated, wherein the water replenishment instruction is used to start the water storage pump, and the water storage pump replenishes the water in the water reservoir into the water tank under the triggering of the water replenishment instruction.

[0061] The predetermined water volume is the water volume set according to actual needs.

[0062] Specifically, a water meter FM0-0 can be set on the pipe at the water inlet of the water reservoir to detect the amount of water flowing into the water reservoir; a water meter FM0-1 can be set on the pipe at the water outlet of the water reservoir to detect the amount of water flowing out of the water reservoir, that is, the amount of water flowing into the water tank; a water meter FM0-2 can be set on the pipe at the water outlet of the water tank to detect the amount of water flowing out of the water tank.

[0063] The controller 120 subtracts the water level of water meter FM0-2 from the water level of water meter FM0-1 to obtain the water level in the water tank, and determines whether the water level in the water tank is lower than the predetermined water level. If the water level in the water tank is lower than the predetermined water level, the controller 120 generates a water replenishment instruction and sends it to the water storage pump to start the water storage pump, so that the water in the water reservoir can be replenished into the water tank.

[0064] In order to further ensure sufficient cooling capacity of the air conditioner, while taking into account water-saving performance and power-saving performance, such as Figure 2 As shown, the controller 120 is configured to determine whether the air-conditioning system 200 is in a predetermined normal working mode period when the air-conditioning system 200 is in a normal working mode, and if it is determined that the air-conditioning system 200 is not in the predetermined normal working mode period, a water-saving mode switching instruction is generated, wherein the water-saving mode switching instruction is used to instruct the air-conditioning system 200 to switch from the normal working mode to the water-saving mode.

[0065] Among them, the preset normal working mode period is to ensure that the water spray volume is supplied according to standard working conditions during the highest temperature period within the set time. In summer, the preset time period can be set to 10:00-18:00, and in spring and autumn, the preset time period can be set to 9:00-19:00.

[0066] It should be noted that the air conditioning unit can achieve three operating modes (called normal operating modes):

[0067] Mode 1: When the outdoor dry-bulb temperature is low, the outdoor air can be directly used to cool the indoor air (the air inside the computer room); Mode 2: When the outdoor dry-bulb temperature rises, the indoor air exchanges heat with the outdoor air through the heat exchanger, but the indoor air supply temperature is still higher than the air supply temperature required by the equipment. At this time, the water supply unit can be turned on to spray water on the surface of the heat exchanger core. In the process of evaporation of the sprayed water, the temperature is lowered and the humidification is increased, and finally the wet-bulb temperature is used to exchange sensible heat with the indoor air; Mode 3: When the indoor return air of the data center still cannot meet the indoor air supply temperature requirements after being processed by Mode 2, the mechanical supplementary refrigeration unit needs to be turned on, that is, the compressor module needs to be operated to ensure that the indoor air supply temperature of the data center meets the air inlet temperature of the server and other equipment.

[0068] At present, when switching the operating mode of the air-conditioning system 200, the outdoor temperature is mostly used to control the switching of the system operating mode. This normal mode is suitable for use in areas with sufficient water and electricity. However, in areas with limited resources, if the system is still allowed to switch the operating mode according to the outdoor temperature, the system's consumption of water and electricity can only rely on the performance of the equipment. However, when the equipment performance is limited and there is a performance degradation problem, it is not conducive to resource utilization and operating costs.

[0069] Assuming that a single data center park has about 380 indirect evaporative cooling units installed and the maximum daily water consumption is 10t / unit, the maximum daily water consumption of the park is 3,800t / day, while the municipal pipe network water supply is only 1,000t / day, which cannot meet the operating water requirements of all units in the park. The park needs to build a reservoir. When the park's daily water consumption exceeds the daily municipal water supply, the water stored in the reservoir is used to ensure the normal operation of the air conditioning system 200. According to calculations, if the reservoir is built according to the water consumption of the unit under standard operating conditions, the volume of the reservoir is very large, which is not conducive to construction and water conservation.

[0070] Therefore, the operation and maintenance personnel can input the capacity of the water reservoir, the capacity of the water tank and the model of each air-conditioning unit through the human-computer interaction interface so that the controller 120 can calculate the first preset water supply upper limit and input the air-conditioning system 200 in a predetermined normal working mode period so that the controller 120 can monitor the current period in real time.

[0071] When the controller 120 determines that the current time period is not in the predetermined normal working mode period, it generates a water-saving mode switching instruction and sends it to the electric valve V1 to control the electric valve V1 to close, stop the linked water supply pump, and control the compressor to start running, that is, switch from the normal working mode to the water-saving mode.

[0072] When the controller 120 determines that the current period is in the predetermined normal working mode period and the total water consumption has not reached the first preset water supply upper limit, the controller 120 generates a spray instruction to control the electric valve V1 to open and link the water supply pump to operate.

[0073] After the set time ends, the next cycle begins, and the controller 120 of the air-conditioning system 200 controls the electric valve V1 to open automatically. At the same time, a reminder message can be sent to the operation and maintenance personnel so that the operation and maintenance personnel can check whether the electric valve V1 of the water supply unit is open. If not, the operation and maintenance personnel can send an opening command to the electric valve V1 of the water supply unit through the human-computer interaction interface to control the electric valve V1 of the water supply unit to open.

[0074] For example, the set duration is set to 0:00-24:00, the first preset water supply upper limit is A, and the preset time period in summer is set to 10:00-18:00. In this way, during the two time periods of 0:00-10:00 and 18:00-24:00, the working mode of the air-conditioning system 200 is an abnormal working mode, and the order of the working modes is: mode 1, mode 3, mode 2; during the time period of 10:00-18:00, the working mode of the air-conditioning system 200 is a normal working mode, and the order of the working modes is: mode 1, mode 2, mode 3.

[0075] When the controller 120 determines that the current time is 6:00 or 21:00, the heat exchange unit alone cannot provide sufficient cooling capacity. At this time, the compressor is used for cooling, and the electric valve V1 is controlled to be closed, and the linked water supply pump stops running to achieve water-saving performance.

[0076] When the controller 120 determines that the current time is 14:00 and the total water consumption reaches A, it controls the electric valve V1 to close, stops the linked water supply pump, and controls the compressor to start running to achieve water-saving performance.

[0077] When the controller 120 determines that the current time is 14:00 and the total water consumption has not reached A, the electric valve V1 is controlled to remain open, the linked water supply pump is controlled to remain in operation, and the compressor is controlled to remain in a stopped state to achieve power saving performance.

[0078] In the air conditioning control system of a data center provided by the embodiment of the present disclosure, when the air conditioning system is in the normal working mode, the controller determines whether to generate a water-saving mode switching instruction by judging whether the air conditioning system is in a predetermined normal working mode period, wherein, when it is judged that the air conditioning system is not in the predetermined normal working mode period, a water-saving mode switching instruction is generated to control the air conditioning system to switch from the normal working mode to the water-saving mode. Thus, the system can further take into account both water-saving performance and power-saving performance while ensuring sufficient air conditioning cooling capacity, and is easy to implement.

[0079] In order to further ensure sufficient cooling capacity of the air conditioner, while taking into account water-saving performance and power-saving performance, such as Figure 3As shown, the controller 120 is configured to obtain the water consumption of each air-conditioning unit in the air-conditioning system 200 within a set time period, and determine whether each air-conditioning unit meets the second working mode switching conditions based on the water consumption. If it is determined that there is an air-conditioning unit among the air-conditioning units that meets the second working mode switching conditions, a second working mode switching instruction is generated, wherein the second working mode switching instruction is used to instruct the air-conditioning unit that meets the second working mode switching conditions to switch to the water-saving working mode.

[0080] Specifically, the operation and maintenance personnel can input the capacity of the water reservoir, the capacity of the water tank and the model of the air-conditioning unit through the human-computer interaction interface of each air-conditioning unit to calculate the second preset water supply upper limit, wherein the sum of the second preset water supply upper limits of all air-conditioning units in the air-conditioning system 200 is less than or equal to the first preset water supply upper limit.

[0081] After obtaining the water consumption of each air-conditioning unit within the set time, the controller 120 determines whether each air-conditioning unit meets the second working mode switching conditions based on the water consumption, such as determining whether the water consumption of any air-conditioning unit within the preset time reaches the second preset water supply upper limit.

[0082] If the water consumption of an air-conditioning unit reaches the second preset water supply upper limit within the preset time, a second working mode switching instruction is generated and sent to the air-conditioning unit that meets the second working mode switching condition, so as to control the electric valve at the water inlet of the air-conditioning unit that meets the second working mode switching condition to close, and control the compressor to operate, so that the air-conditioning unit that meets the second working mode switching condition switches to the water-saving working mode. For example, assuming that the water consumption of the first air-conditioning unit reaches the second preset water supply upper limit within the preset time, but the total water consumption does not reach the first preset water supply upper limit, at this time, the electric valve V1-1 at the water inlet of the first air-conditioning unit is controlled to close, and the compressor of the first air-conditioning unit is started to operate.

[0083] If the total water consumption reaches the first preset water supply upper limit, a first working mode switching instruction is generated, and the first working mode switching instruction is sent to the electric valve V1 to control the electric valve V1 to close, disconnect the water supply of the water supply pipeline, and link the water supply pump to stop running. At the same time, it is sent to the compressor to control the compressor to start running, that is, to switch the air-conditioning system 200 to the water-saving working mode.

[0084] After the set time ends, the next cycle begins, and the controller 120 controls the electric valve V1 of the water supply unit and the electric valve V1-n at the water inlet of the air-conditioning unit to open automatically. At the same time, a reminder message can be sent to the operation and maintenance personnel so that the operation and maintenance personnel can check whether the electric valve V1 and the electric valve V1-n at the water inlet of the air-conditioning unit are opened. If not, the operation and maintenance personnel can send an opening command to the electric valve V1 of the water supply unit and the electric valve V1-n at the water inlet of the air-conditioning unit through the human-computer interaction interface to control the opening of the electric valve V1 of the water supply unit and the electric valve V1-n at the water inlet of the air-conditioning unit.

[0085] In the air conditioning control system of a data center provided by the embodiment of the present disclosure, the controller obtains the water consumption of each air conditioning unit in the air conditioning system within a set time, and judges whether each air conditioning unit meets the second working mode switching condition based on the water consumption. If it is judged that there is an air conditioning unit among the air conditioning units that meets the second working mode switching condition, a second working mode switching instruction is generated to control the air conditioning unit that meets the second working mode switching condition to operate in a water-saving mode. As a result, the system can further take into account water-saving performance and power-saving performance while ensuring sufficient air conditioning cooling capacity, and is easy to implement.

[0087] In step S401, the total water consumption of the air conditioning system within a set time period is obtained.

[0088] In step S402, based on the total water consumption, it is determined whether the air conditioning system meets the working mode switching conditions.

[0089] In step S403, if it is determined that the air-conditioning system meets the working mode switching condition, a first working mode switching instruction is generated, wherein the first working mode switching instruction is used to instruct the air-conditioning system to switch to the water-saving working mode.

[0090] The first working mode switching instruction includes a closing instruction of the electric valve, and the electric valve disconnects the water supply of the water supply pipeline when triggered by the closing instruction.
