[0042] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Reference Figure 1 , Figure 1 The structure block diagram of the first embodiment of the control system of the efficient computer room of the present invention comprises: an operation state setting module 10, a joint optimization module 20, a variable parameter determination module 30 and a target PLC controller 40 connected in sequence.

[0045] In this embodiment, the operating status setting module 10 in the control system 100 of the high-efficiency computer room refers to a module for setting the operating status of the equipment, and the real-time operating parameters refer to the operating parameters of each device in the current computer room. The operating parameters adopt a time series database, that is, a single piece of data occupies fewer bytes, which makes the data extremely efficient in the query process. After obtaining the real-time operating parameters, the operating status of each device is set according to the real-time operating parameters. After the setting is completed, each device in the current computer room starts to run in the operating status, that is, the entire current computer room starts working, and as the environment changes and the weather conditions change, the operating status of the current computer room will also change accordingly, for example, the number of control devices, the matching of equipment operating parameters, etc.

[0046] In this embodiment, the joint optimization module 20 in the control system 100 of the high-efficiency computer room refers to optimizing the working state of the current computer room when the total energy consumption is lowest on the basis of meeting the cooling load required in the specified area. Specifically, it is obtained by using the target energy consumption mathematical model based on the preset demand cooling load. The target energy consumption mathematical model refers to a mathematical model for calculating the total energy consumption of the current computer room, and the preset demand cooling load refers to the cooling load required in the specified area. The following rules need to be followed in the overall joint optimization process: avoid local optimal feedforward calculation to ensure stable operation, and continuously revise the target energy consumption mathematical model.

[0047] Furthermore, the preset demand cooling load is calculated by the target cooling load device within a preset time interval, that is, the required load is measured by the target cooling load device in the specified area every preset time. After obtaining the preset demand cooling load, the energy balance of the entire target computer room is first ensured through the target energy balance mathematical model, and then the target energy consumption mathematical model is used to solve the working state of the current computer room when the total energy consumption is lowest according to the preset global optimization algorithm.

[0048] Furthermore, the current cooling load refers to the total cooling load when each device is operating in the set operating state. Then, it is determined whether the current cooling load meets the preset demand cooling load. If so, it indicates that the current computer room meets the cooling load requirements. At this time, the target energy consumption mathematical model is directly used to solve the current computer room's working state when the total energy consumption is the lowest according to the preset global optimization algorithm. If not, it is necessary to adjust the cooling parameters of each device in the current computer room through the cooling load adjustment strategy. The cooling load adjustment strategy refers to the strategy for adjusting the cooling load of each device. The cooling load adjustment strategy is determined by the cooling load difference between the current cooling load and the preset demand cooling load. Specifically, the cooling load adjustment strategy can increase or decrease the cooling load of each device until the adjusted cooling load of each device meets the preset demand cooling load. Then, the target energy consumption mathematical model is used to solve the current computer room's working state when the total energy consumption is the lowest according to the preset global optimization algorithm.

[0049] Furthermore, the current total energy consumption refers to the total energy consumption of each device in the current computer room, which is specifically obtained by calculating the energy consumption of each device through the target energy consumption mathematical model. When the current total energy consumption is much greater than the preset energy consumption threshold, it indicates that the total energy consumption of the current computer room is not the lowest. At this time, it is necessary to adjust the energy consumption parameters of each device in the current computer room. The historical cooling load range refers to the range composed of the historical maximum cooling load and minimum cooling load of each device. The maximum cooling load is then extracted from the historical cooling load range. According to the maximum cooling load and the preset cooling load threshold, the devices are divided into the first energy-influencing device and the second energy-influencing device. The first energy-influencing device refers to the device that has a great impact on the energy consumption of the current computer room. Specifically, when the energy consumption parameter of the device is adjusted by 1 unit, The energy consumption of the current computer room changes by 10 units or more. The second energy-influencing equipment refers to equipment that has a smaller impact on the energy consumption of the current computer room. Specifically, the energy consumption parameters of the equipment are adjusted by 1 unit. The energy consumption of the current computer room changes by less than 10 units. When it is determined that the total energy consumption difference is greater than the target energy consumption threshold, it indicates that the energy consumption of the current computer room needs to be significantly adjusted. In order to improve the adjustment efficiency, a strategy is adopted to first adjust the energy consumption parameters of the first energy-influencing equipment and then adjust the energy consumption parameters of the second energy-influencing equipment. Then, the preset global optimization algorithm is used to iterate in the above manner to obtain an energy consumption set, and then the lowest energy consumption is selected from the energy consumption set. At this time, each device is controlled to operate with the parameters corresponding to the lowest energy consumption of the current computer room, which is the working state of the current computer room.

[0050] In this embodiment, the control system 100 of the high-efficiency computer room also includes a model construction module. After obtaining the characteristic information of each device in the current computer room, an energy consumption mathematical model corresponding to each device is constructed based on the characteristic information. That is, different devices correspond to different energy consumption mathematical models. The association relationship refers to the relationship between the various devices in the current computer room, for example, the connection relationship between the refrigeration host and the cooling tower. Then, the target energy consumption mathematical model of the entire current computer room is established based on the energy consumption mathematical model of each device.

[0051] In this embodiment, the control system 100 of the high-efficiency computer room also includes an high-efficiency computer room judgment module, which specifically calculates the comprehensive energy efficiency of the current computer room based on the total cooling capacity of the current computer room and the energy consumption of each device. When the comprehensive energy efficiency is greater than a preset comprehensive energy efficiency threshold, the current computer room is determined to be a high-efficiency computer room. The formula for calculating the comprehensive energy efficiency is comprehensive energy efficiency EERs = total cooling capacity of the current computer room / power consumption of each device. When the current comprehensive energy efficiency is greater than the preset comprehensive energy efficiency threshold, the current computer room is determined to be a high-efficiency computer room. The preset comprehensive energy efficiency threshold can be set to 5.0. In this embodiment, it includes but is not limited to a refrigeration host, a chilled water pump, a cooling water pump and a cooling tower, specifically a refrigeration host, a cooling tower, a water pump, an energy valve, a plate heat exchanger, a terminal device and a water processor.

[0052] Understandably, the reference Figure 2 , Figure 2 Schematic diagram of comprehensive energy efficiency. Specifically, comprehensive energy efficiency is calculated by the ratio of power consumption of all relevant equipment, such as the total cooling capacity, the refrigeration main unit, the chilled water pump, the cooling water pump, and the cooling tower. Compared with the traditional computer room, the comprehensive energy efficiency of the high-efficiency computer room constructed in this embodiment is greater than the preset comprehensive energy efficiency threshold. For example, the current comprehensive energy efficiency is between 5.0 and 6.0, while the comprehensive energy efficiency of the traditional computer room is 3.5. In addition, the energy consumption of the chiller in the high-efficiency computer room is also much lower than that of the chiller in the traditional computer room.

[0053] It should be understood that reference Figure 3 , Figure 3 This is a schematic diagram of energy efficiency trends. Specifically, as time goes by, the energy efficiency of the traditional computer room shows a downward trend, and the decline is large. However, the energy efficiency of the high-efficiency computer room constructed in this embodiment shows a stable trend over time, that is, the high-efficiency computer room continues to work efficiently in a high-energy-efficiency manner.

[0054] Furthermore, after the various devices are installed, the entire target high-efficiency computer room needs to be monitored in real time. Specifically, this involves 24-hour, remote, and non-delayed monitoring via a network cloud platform. Equipment operation reports are automatically generated, and efficiency anomalies are diagnosed. Specifically, the monitoring module monitors the target high-efficiency computer room and generates corresponding equipment operation reports. The corresponding work efficiency is analyzed based on the equipment operation reports. If the work efficiency falls below a preset efficiency threshold, an efficiency anomaly is detected. In this case, the equipment operation report needs to be sent to the diagnosis module for diagnosis. After receiving the equipment operation report, the diagnosis module uses an artificial intelligence algorithm to compare the working status of the high-efficiency computer room before installation with the working status of the target high-efficiency computer room installed at the equipment installation location to identify factors affecting efficiency. Based on these factors, a corresponding efficiency improvement strategy is then formulated. The parameter setting module then performs a rationality analysis. If the analysis results meet the requirements, the operating parameters of each target device in the target high-efficiency computer room are adjusted according to the efficiency improvement strategy. After adjustment, the current computer room achieves the lowest overall energy consumption while meeting the cooling load, and the current comprehensive energy efficiency exceeds the preset comprehensive energy efficiency threshold. A hybrid data source engine is used to automatically identify faults, ensuring fault-tolerant operation of the high-efficiency computer room system.

[0055] In this embodiment, the variable parameter determination module 30 in the control system 100 of the high-efficiency computer room refers to a module for determining the controlled variable parameters. The joint optimization module 20 solves the energy consumption parameters that can reduce the total energy consumption of the current computer room, and the controlled variable parameters refer to the parameters in the energy consumption parameters that can quickly and accurately reduce energy consumption to the minimum value. After determining the controlled variable parameters, the controlled variable parameters are forwarded to the target PLC controller 40.

[0056] In this embodiment, after the target PLC controller 40 in the control system 100 of the high-efficiency computer room obtains the controlled variable parameters, the PLC controllers corresponding to each device adjust the controlled variable parameters. During the adjustment process, the operating status of each device will change from an operating state to an operating state that meets the preset required cooling load and has the lowest total energy consumption of the current computer room, that is, the current computer room operates at the highest efficiency.

[0057] When the preset cooling load is met and the current computer room has the lowest total energy consumption, the target computer room constructed by each target device will be assembled in the target area according to the equipment assembly rules. The equipment assembly rules refer to the rules for assembling the designed target computer room, including assembling each target device first, then connecting each target device, and finally setting the target device to operate with the adjusted operating parameters to achieve the lowest overall energy consumption under the premise of meeting the cooling load. Generally, multiple hosts will be installed, that is, for backup and normal use, and run the cooling system at the same time when the cooling demand is large. For example, a shopping mall requires 2 chilled water hosts, 3 chilled water pumps, 3 cooling water pumps, 1 set of strong and weak current control cabinets, 1 set of BMS control cabinets, 1 set of water treatment, 8 electric butterfly valves, 1 set of constant pressure water supply, 6 Y-type filters, sensors. For air-conditioning systems with multiple host requirements such as data centers, they are mainly divided into multiple modules, including host modules, freezing modules, cooling modules, and cooling towers. For large commercial complexes, venues, District cooling, etc., requires system modular design and splicing. After each device is transported to the specified area, each device is installed in an assembled manner. The above method can improve installation efficiency and reduce errors.

[0058] In this embodiment, the real-time operating parameters of each device in the current computer room are obtained through the operating status setting module 10, and the operating status of each device is set according to the real-time operating parameters; the joint optimization module 20 solves the working status of the current computer room when the total energy consumption is lowest according to the target energy consumption mathematical model and the preset required cooling load; the variable parameter determination module 30 determines the controlled variable parameters according to the working status of the current computer room when the total energy consumption is lowest, and sends the controlled variable parameters to the target PLC controller; the target PLC controller 40 adjusts the operating status of each device according to the controlled variable parameters, so that the current computer room operates efficiently in the adjusted state; controlling the operating status of each device in the current computer room in the above manner so that the current computer room operates in an efficient state can effectively improve the cooling efficiency and greatly reduce energy consumption.

[0059] refer to Figure 4 , based on the above Figure 4 The embodiment shown provides the second embodiment of the control system for a high-efficiency computer room of the present invention.

[0060] In this embodiment, the selection module 01, since there are multiple target devices for building an efficient computer room, and the efficient selection rules used in selecting different target devices are different, it is necessary to adopt proprietary efficient selection rules to select corresponding devices, that is, to match the type of each device with each selection rule of the target efficient selection rule. The types of each device include refrigeration host type, cooling tower type, water pump type, energy valve type, plate heat exchanger type, terminal device type and water treatment device type. Accordingly, each device includes a refrigeration host, cooling tower, water pump, energy valve, plate heat exchanger, terminal device and water treatment device.

[0061] Furthermore, the matching results show that the refrigeration host is selected using the high-efficiency refrigeration host selection rule, the cooling tower is selected using the high-efficiency cooling tower selection rule, the water pump is selected using the high-efficiency water pump selection rule, the terminal equipment is selected using the high-efficiency terminal equipment selection rule, the plate heat exchanger is selected using the high-efficiency plate heat exchanger selection rule, the energy valve is selected using the high-efficiency energy valve selection rule, and the water processor is selected using the high-efficiency water processor selection rule. The refrigeration host is selected using the high-efficiency refrigeration host selection rule. As the most important equipment in a high-efficiency cold station, its selection is particularly important. This embodiment, based on the implementation of a standard high-efficiency computer room and in combination with relevant domestic and international standards, provides key requirements for refrigeration host selection, providing a good foundation for efficient operation of the air-conditioning system. Specifically, the requirements for selecting the refrigeration host are obtained based on the high-efficiency refrigeration host selection rule, including but not limited to: ① configuring a fixed-frequency variable-frequency ratio based on annual load analysis (a peak of 2400 RT can be configured with a certain high-efficiency fixed-frequency host); ② national standard operating performance requirements for the host (level 1 energy efficiency): variable-frequency host: (GB) IPLV ≥ 8.5, national standard COP ≥ 6.1; fixed-frequency host: (GB) COP ≥ 6.6, national standard IPLV ≥ 7.0; ③ Each host must provide cooling water at 18℃ 132℃ at each temperature of 10% 1100% of the two-device variable flow performance parameters (two-device flow ≥ 60% variable flow, less than 60% is 60% flow); ④ For systems with a maximum load of more than 1200RT, a small-capacity host must be configured, depending on the annual load analysis, generally 5% 115% of the maximum load; ⑤ For systems with ≤ 3 hosts, it is recommended to use full frequency conversion; for systems with ≥ 4 hosts, it is recommended to use N+2 (small machine) configuration, with the small machine using a variable frequency host, and the total capacity of the two hosts not less than 70% of the capacity of a single large machine; ⑥ For magnetic levitation hosts, it is recommended to select according to the specific needs of the owner and select the cooling tower using the high-efficiency cooling tower selection rules. The correct selection of the cooling tower will affect the success or failure of the high-efficiency computer room.During actual operation, the number of cooling towers and fan frequency are directly controlled according to the wet-bulb approximation, which not only reduces the energy consumption of the cooling tower, but also ensures that the host operates in the high-efficiency range. Specifically, the requirements for selecting the cooling tower are obtained according to the high-efficiency cooling tower selection rules, including but not limited to ① The cooling tower capacity is the same and is not configured with the host size; ② Approximate selection of cooling tower capacity: 1m3 / h water volume of cooling tower = 1RT cooling capacity of chiller; ③ The approximation under the three conditions of 5-degree temperature difference of cooling water, 27.5*(wet-bulb temperature), and actual condenser flow is ≤2.5℃; ④ Cooling tower motor power: ≤0.03w / m3 / h (water volume); ⑤ Equipped with uniform water distribution technology at 30% flow (cross-flow tower is preferred in most cases); ⑥ The cooling tower motor supports a wide frequency conversion range of 20HZ150HZ; ⑦ Clarify the noise control indicators based on the noise sensitive points around the project (generally, it is necessary to clarify the distance between the noise sensitive point or the building red line and the nearest cooling tower outlet and the corresponding noise indicators); ⑧ Adequate air intake and exhaust conditions must be ensured around the cooling tower. Minimize the number of large-sized items such as various fans, heat pumps, and air ducts, and use efficient water pump selection rules to select water pumps, which are the power source for the cooling water and chilled water circulation of the air-conditioning system.However, cooling water pumps and chilled water pumps account for an average of 15% to 120% of the system's energy consumption throughout the year. Therefore, in addition to system temperature differences and variable frequency control logic, reducing water pump energy consumption also requires that the pump selection meet certain criteria, including but not limited to: ① Variable frequency motors: Use a forced ventilation cooling system to ensure effective heat dissipation at any motor speed, enabling long-term high or low speed operation; ② Flow rate requirements: The design flow rate must not exceed 75% of the maximum flow rate; ③ Efficiency requirements: Pumps with a water flow of 200 m³ / h or more must have an efficiency of at least 80% (depending on the project's computer room conditions, vertical pumps are generally preferred); ④ Pump head: Based on the experience of many successful and efficient computer rooms, the chilled water pump is approximately 25 m, and the cooling water pump is approximately 20 m. The terminal equipment selection rules for efficient terminal equipment are used to select the terminal equipment. The selection of the terminal equipment directly affects the chilled water pump head, which in turn affects the chilled water pump energy consumption and the chilled water supply temperature, which in turn affects the energy efficiency of the main unit. Specifically, the requirements for terminal equipment selection are determined based on the efficient terminal equipment selection rules, including but not limited to: ① Each terminal unit must have an AHRI selection. ② The selected heat exchange rate ≥ 105% of the designed heat exchange rate; ③ All surface cooler coils must be equipped with hydrophilic aluminum foil fins; ④ The water pressure drop ≤ 50KPa, and the energy valve selected according to the high-efficiency energy valve selection rules consists of a set of high-precision energy meters + an electric regulating seat valve (DC motor) + a set of control logic. The requirements for selecting the energy valve are obtained according to the high-efficiency energy valve selection rules, including but not limited to ① Effectively solve the dynamic and static hydraulic balance of the air-conditioning system, and realize one-key debugging on the computer network to replace the traditional method (static valve + control valve + dynamic pressure differential valve) to install without adjustment or even if debugging, there will be huge repeated debugging; ② Realize effective temperature difference control at the terminal; ③ Realize digital management of the water system of the terminal equipment The plate heat exchanger is selected using the high-efficiency plate heat exchanger selection rules. Specifically, the plate heat exchanger with the best total heat transfer coefficient, heat transfer efficiency, logarithmic mean temperature difference, number of plates and heat exchange area is selected using the high-efficiency plate heat exchanger selection rules. The flow direction and mode of the liquid will affect the logarithmic mean temperature, and the higher the logarithmic mean temperature, the better the heat transfer effect. Therefore, it is necessary to select a plate heat exchanger with a generally parallel or countercurrent flow of the fluid and a very high logarithmic mean temperature. The water processor is selected using the high-efficiency water processor selection rules. Specifically, the requirements for selecting the water processor according to the high-efficiency water processor selection rules include but are not limited to ① giving priority to the side flow physical and chemical form; ② no water resistance and low power; ③ selecting according to 5% of the system water flow.

[0062] In this embodiment, the type of each device is obtained through the selection module 01, and the type of each device is matched with the target high-efficiency selection rule. According to the matching results, the refrigeration host, cooling tower, water pump, energy valve, plate heat exchanger, terminal device and water treatment device are selected from the several devices. At this time, the selected devices meet the requirements for building an efficient computer room, which can effectively improve the accuracy and efficiency of building an efficient computer room.

[0063] Reference Figure 5 The control system of the efficient computer room of the present invention provides a control method for the efficient computer room. FIG5 is a flow chart of a first embodiment of the control method for the efficient computer room of the present invention. The control system of the efficient computer room includes: an operation state setting module, a joint optimization module, a variable parameter determination module, and a target PLC controller connected in sequence;

[0064] The control method of the high-efficiency computer room includes:

[0065] Step S10: the operation status setting module obtains the real-time operation parameters of each device in the current computer room, and sets the operation status of each device according to the real-time operation parameters.

[0066] It can be understood that configuration parameters refer to the basic parameters configured on the equipment. Different equipment has different corresponding configuration parameters. For example, for the refrigeration host, the real-time operating parameters refer to the operating parameters of each device in the current computer room. After obtaining the real-time operating parameters, the operating status of each device is set according to the real-time operating parameters. After the setting is completed, each device in the current computer room starts to operate in the operating state, that is, the entire current computer room starts working, and as the environment changes and the weather conditions change, the operating status of the current computer room will also change accordingly, for example, the number of control devices, the matching of equipment operating parameters, etc.

[0067] In step S20, the joint optimization module solves the working state of the current computer room when the total energy consumption is lowest according to the target energy consumption mathematical model and the preset required cooling load.

[0068] It should be understood that, on the basis of meeting the cooling load required in the specified area, the current working state of the computer room when the total energy consumption is the lowest is specifically obtained by using the target energy consumption mathematical model to solve according to the preset demand cooling load. The target energy consumption mathematical model refers to the mathematical model for calculating the total energy consumption of the current computer room, and the preset demand cooling load refers to the cooling load required in the specified area.

[0069] It can be understood that the preset demand cooling load is calculated by the target cooling load equipment within a preset time interval, that is, the required load is measured by the target cooling load equipment in the specified area every preset time. After obtaining the preset demand cooling load, the energy balance of the entire target computer room is first ensured through the target energy balance mathematical model, and then the target energy consumption mathematical model is used according to the preset global optimization algorithm to solve the working status of the current computer room when the total energy consumption is the lowest.

[0070] It should be understood that the current cooling load refers to the total cooling load when each device is operating in the set operating state. Then, it is judged whether the current cooling load meets the preset demand cooling load. If so, it indicates that the current computer room meets the cooling load requirements. At this time, the target energy consumption mathematical model is directly used to solve the working state of the current computer room when the total energy consumption is the lowest according to the preset global optimization algorithm. If not, it is necessary to adjust the cooling parameters of each device in the current computer room through the cooling load adjustment strategy. The cooling load adjustment strategy refers to the strategy for adjusting the cooling load of each device. The cooling load adjustment strategy is determined by the cooling load difference between the current cooling load and the preset demand cooling load. Specifically, the cooling load adjustment strategy can increase or decrease the cooling load of each device until the adjusted cooling load of each device meets the preset demand cooling load. Then, the target energy consumption mathematical model is used to solve the working state of the current computer room when the total energy consumption is the lowest according to the preset global optimization algorithm.

[0071] It can be understood that the current total energy consumption refers to the total energy consumption of each device in the current computer room, which is specifically obtained by calculating the energy consumption of each device through the target energy consumption mathematical model. When the current total energy consumption is much greater than the preset energy consumption threshold, it indicates that the total energy consumption of the current computer room is not the lowest. At this time, it is necessary to adjust the energy consumption parameters of each device in the current computer room. The historical cooling load range refers to the range composed of the historical maximum cooling load and minimum cooling load of each device. The maximum cooling load is then extracted from the historical cooling load range. According to the maximum cooling load and the preset cooling load threshold, the various devices are divided into the first energy-influencing device and the second energy-influencing device. The first energy-influencing device refers to the device that has a great impact on the energy consumption of the current computer room. Specifically, the energy consumption parameters of the device are adjusted. When the energy consumption parameter of the equipment is adjusted by 1 unit, the energy consumption of the current computer room changes by 10 units or more. The second energy-influencing equipment refers to the equipment that has a smaller impact on the energy consumption of the current computer room. Specifically, when the energy consumption parameter of the equipment is adjusted by 1 unit, the energy consumption of the current computer room changes by less than 10 units. When it is determined that the total energy consumption difference is greater than the target energy consumption threshold, it indicates that the energy consumption of the current computer room needs to be significantly adjusted. In order to improve the adjustment efficiency, the strategy of first adjusting the energy consumption parameters of the first energy-influencing equipment and then adjusting the energy consumption parameters of the second energy-influencing equipment is adopted. Then, the preset global optimization algorithm is used to iterate in the above manner to obtain an energy consumption set, and then the lowest energy consumption is selected from the energy consumption set. At this time, each device is controlled to operate with the parameters corresponding to the lowest energy consumption of the current computer room, which is the working state of the current computer room.

[0072] It should be understood that after obtaining the characteristic information of each device in the current computer room, an energy consumption mathematical model corresponding to each device is constructed based on the characteristic information, that is, different devices correspond to different energy consumption mathematical models. The association relationship refers to the relationship between the various devices in the current computer room, for example, the connection relationship between the refrigeration host and the cooling tower, and then the target energy consumption mathematical model of the entire current computer room is established based on the energy consumption mathematical model of each device.

[0073] It can be understood that the comprehensive energy efficiency of the current computer room is calculated by combining the total cooling capacity of the current computer room and the energy consumption of each device. When the comprehensive energy efficiency is greater than the preset comprehensive energy efficiency threshold, the current computer room is determined to be a high-efficiency computer room. The formula for calculating the comprehensive energy efficiency is comprehensive energy efficiency EERs = total cooling capacity of the current computer room / energy consumption of each device. When the current comprehensive energy efficiency is greater than the preset comprehensive energy efficiency threshold, the current computer room is determined to be a high-efficiency computer room. The preset comprehensive energy efficiency threshold can be set to 5.0. In this embodiment, it includes but is not limited to chillers, chilled water pumps, cooling water pumps and cooling towers, specifically refrigeration hosts, cooling towers, water pumps, energy valves, plate heat exchangers, terminal equipment and water processors.

[0074] Understandably, the reference Figure 2 , Figure 2 Schematic diagram of comprehensive energy efficiency. Specifically, the comprehensive energy efficiency is calculated based on the total cooling capacity, water units, chilled water pumps, cooling water pumps, and cooling towers. Compared with the traditional computer room, the comprehensive energy efficiency of the high-efficiency computer room constructed in this embodiment is greater than the preset comprehensive energy efficiency threshold. For example, the current comprehensive energy efficiency is between 5.0 and 6.0, while the comprehensive energy efficiency of the traditional computer room is 3.5. In addition, the energy consumption of the chiller in the high-efficiency computer room is also much lower than that of the chiller in the traditional computer room.

[0075] It should be understood that reference Figure 3 , Figure 3 This is a schematic diagram of energy efficiency trends. Specifically, as time goes by, the energy efficiency of the traditional computer room shows a downward trend, and the decline is large. However, the energy efficiency of the high-efficiency computer room constructed in this embodiment shows a stable trend over time, that is, the high-efficiency computer room continues to work efficiently in a high-energy-efficiency manner.

[0076] Step S30: the variable parameter determination module determines controlled variable parameters according to the current working state of the computer room when the total energy consumption is lowest, and sends the controlled variable parameters to the target PLC controller.

[0077] It can be understood that the energy consumption parameters that can reduce the total energy consumption of the current computer room are solved in the joint optimization module, and the controlled variable parameters refer to the parameters in the energy consumption parameters that can quickly and accurately reduce energy consumption to the minimum value. After determining the controlled variable parameters, the controlled variable parameters are forwarded to the target PLC controller.

[0078] In step S40, the target PLC controller adjusts the operating status of each device according to the controlled variable parameters, so that the current computer room operates efficiently in the adjusted state.

[0079] It should be understood that after obtaining the controlled variable parameters, the PLC controller corresponding to each device adjusts the controlled variable parameters. During the adjustment process, the operating status of each device will change to an operating state that meets the preset required cooling load and has the lowest total energy consumption in the current computer room, that is, the current computer room operates at the highest efficiency.

[0080] When the preset cooling load is met and the current computer room has the lowest total energy consumption, the target computer room constructed by each target device will be assembled in the target area according to the equipment assembly rules. The equipment assembly rules refer to the rules for assembling the designed target computer room, including assembling each target device first, then connecting each target device, and finally setting the target device to operate with the adjusted operating parameters to achieve the lowest overall energy consumption under the premise of meeting the cooling load. Generally, multiple hosts will be installed, that is, for backup and normal use, and run the cooling system at the same time when the cooling demand is large. For example, a shopping mall requires 2 chilled water hosts, 3 chilled water pumps, 3 cooling water pumps, 1 set of strong and weak current control cabinets, 1 set of BMS control cabinets, 1 set of water treatment, 8 electric butterfly valves, 1 set of constant pressure water supply, 6 Y-type filters, sensors. For air-conditioning systems with multiple host requirements such as data centers, they are mainly divided into multiple modules, including host modules, freezing modules, cooling modules, and cooling towers. For large commercial complexes, venues, District cooling, etc., requires system modular design and splicing. After each device is transported to the specified area, it is installed in an automated assembly manner. The above method can improve installation efficiency and reduce errors.

[0081] This embodiment obtains the real-time operating parameters of each device in the current computer room through the operating status setting module, and sets the operating status of each device according to the real-time operating parameters; the joint optimization module solves the working status of the current computer room when the total energy consumption is lowest according to the target energy consumption mathematical model and the preset required cooling load; the variable parameter determination module determines the controlled variable parameters according to the working status of the current computer room when the total energy consumption is lowest, and sends the controlled variable parameters to the target PLC controller; the target PLC controller adjusts the operating status of each device according to the controlled variable parameters, so that the current computer room operates efficiently in the adjusted state; controlling the operating status of each device in the current computer room in the above manner so that the current computer room operates in an efficient state can effectively improve the cooling efficiency and greatly reduce energy consumption.
