Description

Technical Field

[0001] This application relates to the field of automatic control technology for data center environmental control rooms, and in particular to an automatic control method and device for data center environmental control rooms. Background Technology

[0002] A data center is a facility specifically designed to host and manage a large number of computer servers, network devices, and storage devices. It provides a secure, stable, and efficient environment for operating and maintaining an organization's IT infrastructure. The data center should have a reliable power supply system, including backup generators, UPS (Uninterruptible Power Supply), and power distribution equipment. This ensures that the equipment in the data center can operate normally during sudden power outages or power fluctuations. Due to the high-density operation of a large number of devices, the data center needs to maintain stable temperature and humidity. Air conditioning and cooling systems ensure that the equipment does not overheat, affecting its performance and lifespan. Furthermore, the data center should have remote monitoring and management capabilities, allowing administrators to remotely access and manage the equipment at any time, perform maintenance and troubleshooting, and ensure the safe, stable, and efficient operation of the equipment and data.

[0003] Currently, in data center environmental control rooms, the terminal air conditioning and cooling systems primarily rely on operators to manually turn the equipment on and off at the site and adjust the machine's operating status based on monitoring data. This not only wastes manpower and increases costs, but also hinders real-time monitoring and adjustment, making rapid adjustments and energy conservation inefficient. Furthermore, it fails to promptly detect and issue alarm signals when faults occur. Therefore, this application proposes an automatic control method and device for data center environmental control rooms to at least partially solve the problems that may exist in the prior art. Summary of the Invention

[0004] In view of the aforementioned problems, this application is made to provide an automatic control method and apparatus for data center environmental control rooms that overcomes or at least partially solves the aforementioned problems, comprising: An automatic control method for the environmental control room of a data center includes: acquiring COP data of indirect evaporative cooling; Based on the comparison between the indirect evaporative cooling COP data and a preset threshold, the environmental and equipment status of the environmental monitoring room are determined according to the comparison results. Based on the environmental and equipment conditions, the automatic on / off logic control of the indirect evaporative cooling system is executed.

[0005] Optionally, obtaining COP data includes: The humidity, power, supply air temperature, return air temperature, and motor speed parameters in the motorized cooling room are obtained, and the COP data of indirect evaporative cooling are calculated based on these parameters.

[0006] Optionally, the step of acquiring humidity, power, supply air temperature, return air temperature, and motor speed parameters in the motorized cooling room, and calculating indirect evaporative cooling COP data based on these parameters includes: Obtain the flow rate and return water temperature difference of chilled water pipe A, as well as the flow rate and return water temperature difference of chilled water pipe B; The cooling capacity of the refrigeration unit can be obtained using the formula: Flow rate of chilled water pipe A * Temperature difference of return water in pipe A * 1.163 + Flow rate of chilled water pipe B * Temperature difference of return water in pipe B * 1.163. Based on the formula: Refrigeration capacity / (Refrigeration unit active power + Cooling pump active power + Chilled water pump active power + Cooling tower active power), the COP data of the refrigeration system is obtained. Based on the formula: Total cooling capacity of the chiller system + Total energy consumption of the chiller / 4.2 / (Average supply water temperature of cooling mains A and B - Average return water temperature of cooling mains A and B), the total flow rate of the cooling tower can be obtained. Based on the formula: (Average supply water temperature of cooling main pipes AB - Average return water temperature of cooling main pipes AB) * Total cooling tower flow rate * 1.163, the total heat dissipation of the cooling tower is obtained. Based on the formulas: chilled pump flow rate (L / s) * [rated frequency head of chilled pump * (actual frequency / rated frequency)²] / 10² / chilled pump power, and the formula: cooling pump flow rate (L / s) * [rated frequency head of cooling pump * (actual frequency / rated frequency)²] / 10² / cooling pump power, the efficiency data of the chilled pump and the cooling pump are obtained respectively. Based on the formula: (evaporative cooling return air temperature - evaporative cooling supply air temperature) * 46400 * 0.325 / 1000 * indoor fan speed (%) / 100 + (100 - return air temperature) * 0.04, the indirect evaporative cooling capacity data is obtained. Based on the formula: Indirect evaporative cooling capacity / Indirect evaporative cooling power, the COP data for indirect evaporative cooling is obtained.

[0007] Optionally, the step of comparing the indirect evaporative cooling COP data with a preset threshold, and determining the environmental and equipment status of the environmental control room based on the comparison result, includes: When the indirect evaporative cooling COP data is greater than 4, it is determined that the unit in the dynamic environment room is in the start-up operation state; After a 15-minute delay, a status check is performed. The status check includes the following: if the unit's own COP data is greater than the chiller system's COP data plus 0.2, the unit continues to run; otherwise, a shutdown command is used to switch the unit to a shutdown state.

[0008] Optionally, the step of comparing the indirect evaporative cooling COP data with a preset threshold and determining the environmental and equipment status of the environmental control room based on the comparison result further includes: When the indirect evaporative cooling COP data is less than 4, determine whether the outdoor wet-bulb temperature is stable relative to the preset temperature threshold. When the outdoor wet-bulb temperature is not less than the temperature threshold or fluctuates around the temperature threshold, the outdoor wet-bulb temperature is reassessed to determine whether it is stable relative to the preset temperature threshold. If the result remains unchanged, a start command is sent to confirm that the unit is in start-up operation mode.

[0009] Optionally, it also includes: when the temperature of the outdoor heating bulb is greater than a preset temperature threshold, issuing a shutdown command to determine that the unit is always in standby mode.

[0010] Optionally, when the indirect evaporative cooling COP data is less than 4, determining whether the outdoor wet-bulb temperature is stable relative to a preset temperature threshold includes: When the indirect evaporative cooling COP data is less than 4, determine whether the outdoor temperature bulb temperature is less than 25°C for a continuous period of 10 minutes; if it is less than 25°C, send a start command to start the unit.

Based on the detailed data, determine whether there are any abnormalities in the environmental monitoring room. If an abnormality is found, issue an alarm.

[0012] Optionally, the step of calculating pPUE data using measured energy consumption data and corresponding energy efficiency formulas includes: By measuring the energy consumption of the precision air conditioner and using the calculation formula: [(actual fan speed / rated fan speed) 3 * total rated fan power] + energy consumption of the precision air conditioner, the power data of the precision air conditioner is obtained. The total rated fan power is the sum of the power of the total number of fans. The standby power data of the precision air conditioner was obtained through measurement. Transformer loss data can be obtained using the formula: Input power of front-end transformer - Output power of transformer. The UPS loss data can be obtained using the formula: Front-end UPS input power - UPS output power; The transformer efficiency data can be obtained using the formula: (Transformer output power / Transformer front-end input power) * 100; The UPS efficiency can be obtained using the formula: (UPS output power / UPS front-end input power) * 100.

Attached Figure Description

[0017] To more clearly illustrate the technical solution of this application, the drawings used in the description of this application will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0018] Figure 1 This is a flowchart illustrating the steps of an automatic control method for a data center environmental control room according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of an automatic control device for a data center environmental control room according to an embodiment of this application; Figure 3 This is a schematic diagram of the structure of a computer device provided in an embodiment of this application. Detailed Implementation

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Reference Figure 1 The diagram illustrates a flowchart of the steps of an automatic control method for a data center environmental control room according to an embodiment of this application, which includes: Step S101: Obtain indirect evaporative cooling COP data; Step S102: Based on the comparison of the indirect evaporative cooling COP data and the preset threshold, determine the environmental status and equipment status of the environmental control room based on the comparison results; Step S103: Based on the environmental and equipment conditions, execute the indirect evaporative cooling automatic start-up and shutdown logic control.

[0021] In this embodiment, the above method addresses the drawbacks of current manual control and monitoring of environmental control rooms. The aforementioned automatic control method for environmental control rooms collects and analyzes indirect evaporative cooling COP data and compares this data with preset thresholds to determine the environmental and equipment status of the environmental control room. Based on the comparison results, it automatically executes the on / off logic control of the indirect evaporative cooling system. The entire process is automatic, essentially achieving unattended operation. It eliminates the need for operators to monitor and adjust the air conditioning and cooling systems in real time, relying instead on automatic control. By automatically acquiring and analyzing monitoring data and comparing it with preset thresholds, the system can automatically determine the environmental and equipment status, thereby automatically executing the on / off logic control. Compared to manual operation, the automatic control method can respond and adjust the system status more quickly. It can acquire and analyze monitoring data in real time, enabling timely decisions and adjustments, which helps improve the energy efficiency and operational efficiency of the data center, reducing energy waste and costs. Automatic control methods can monitor equipment status and promptly detect and issue alarm signals when malfunctions occur, improving the reliability and security of the computer room. This allows administrators to handle faults promptly and reduce potential losses and risks. The aforementioned methods can monitor the cooling efficiency (COP) of operating equipment in real time. When the equipment's COP is higher than the chiller system's COP, it can continue operating; when it falls below the chiller system's COP, the equipment shuts down, effectively reducing computer room energy consumption and achieving optimal equipment operating efficiency. When equipment malfunctions, the indirect evaporative cooling COP data is reflected promptly and can be notified to data center personnel via environmental alarms for handling, preventing energy waste.

[0022] The following will further describe an automatic control method for the environmental control room of a data center in this exemplary embodiment.

[0023] In one embodiment of the present invention, the specific process of "acquiring indirect evaporative cooling COP data" in step S101 can be further described in conjunction with the following description, including acquiring humidity, power, supply air temperature, return air temperature and motor speed parameters in the motor room, and calculating indirect evaporative cooling COP data based on these parameters.

[0024] Furthermore, the acquisition of humidity, power, supply air temperature, return air temperature, and motor speed parameters in the motorized cooling room, and the calculation of indirect evaporative cooling COP data based on these parameters, includes: Obtain the flow rate and return water temperature difference of chilled water pipe A, as well as the flow rate and return water temperature difference of chilled water pipe B; The cooling capacity of the refrigeration unit can be obtained using the formula: Flow rate of chilled water pipe A * Temperature difference of return water in pipe A * 1.163 + Flow rate of chilled water pipe B * Temperature difference of return water in pipe B * 1.163. Based on the formula: Refrigeration capacity / (Refrigeration unit active power + Cooling pump active power + Chilled water pump active power + Cooling tower active power), the COP data of the refrigeration system is obtained. Based on the formula: Total cooling capacity of the chiller system + Total energy consumption of the chiller / 4.2 / (Average supply water temperature of cooling mains A and B - Average return water temperature of cooling mains A and B), the total flow rate of the cooling tower can be obtained. Based on the formula: (Average supply water temperature of cooling main pipes AB - Average return water temperature of cooling main pipes AB) * Total cooling tower flow rate * 1.163, the total heat dissipation of the cooling tower is obtained. Based on the formulas: chilled pump flow rate (L / s) * [rated frequency head of chilled pump * (actual frequency / rated frequency)²] / 10² / chilled pump power, and the formula: cooling pump flow rate (L / s) * [rated frequency head of cooling pump * (actual frequency / rated frequency)²] / 10² / cooling pump power, the efficiency data of the chilled pump and the cooling pump are obtained respectively. Based on the formula: (evaporative cooling return air temperature - evaporative cooling supply air temperature) * 46400 * 0.325 / 1000 * indoor fan speed (%) / 100 + (100 - return air temperature) * 0.04, the indirect evaporative cooling capacity data is obtained. Based on the formula: Indirect evaporative cooling capacity / Indirect evaporative cooling power, the COP data for indirect evaporative cooling is obtained.

[0025] As an example, the real-time COP of the equipment is calculated by collecting data such as humidity, power, supply air temperature, return air temperature, and motor speed from the dynamic environmental monitoring (VORM) device. Simultaneously, the COP data of the chiller system is calculated using data from the existing VORM device. Once both devices have COP values, the outdoor wet-bulb temperature collected by the VORM is used. Since each indirect evaporator was previously started up and operated at multiple different outdoor wet-bulb temperatures, it is determined at which outdoor wet-bulb temperature is generally better than the chiller system's COP data. This outdoor wet-bulb temperature is then used as the start-up condition to execute the automatic shutdown logic control of the indirect evaporative chiller.

[0026] The operating efficiency of each device is calculated using formulas, and real-time data is then generated through program logic. This allows for real-time evaluation of operating efficiency, enabling on-duty personnel to promptly identify and address any anomalies. This solves the problem of traditional environmental monitoring systems (EHS) data being collected from single points, making it impossible to determine if device operating efficiency is within normal ranges. Previously, EHS data had to be exported and recalculated later, increasing labor costs and causing energy waste due to the lack of real-time data and delayed anomaly detection. This new system effectively reduces data center energy consumption while ensuring equipment operates under optimal conditions, extending equipment lifespan.

[0027] In one embodiment of the present invention, the specific process of step S102, "comparing the indirect evaporative cooling COP data with a preset threshold and determining the environmental and equipment status of the environmental control room based on the comparison results," can be further explained in conjunction with the following description.

[0028] The automatic start / stop logic for indirect evaporative cooling is as follows: the COP of indirect evaporative cooling is typically 5 or higher during normal system operation. If the COP of the indirect evaporative cooling unit (the value obtained by running the calculation program through the previous formula) is greater than 4, a conditional judgment is made. If it is greater than 4, it is judged that the unit has been started and is running normally. The purpose is to prevent the program from issuing a shutdown command when the unit has already started running but the indirect evaporative cooling program has not yet read the COP value of the unit due to the data acquisition cycle. When the indirect evaporative cooling COP data is greater than 4, it is determined that the unit in the dynamic environment room is in the start-up operation state; After a 15-minute delay, a status check is performed. The status check includes the following: if the unit's own COP data is greater than the chiller system's COP data plus 0.2, the unit continues to run; otherwise, a shutdown command is used to switch the unit to a shutdown state.

[0029] When the evaporative chiller's COP data is greater than 4, the program determines that the unit has started up and is running. A 15-minute delay is implemented (this delay prevents the unit's COP from dropping below the chiller system's COP at startup, thus avoiding shutdown). If the unit's COP is higher than the chiller system's COP plus 0.2 (for evaporative chillers to operate at a higher COP, which is more cost-effective), the unit will continue running. When the unit's COP falls below the chiller system's COP plus 0.2, the program issues a shutdown command, and the unit stops. The above logic is then repeated for subsequent start-ups and shutdowns.

[0030] When the indirect evaporative cooling COP data is less than 4, determine whether the outdoor wet-bulb temperature is stable relative to the preset temperature threshold. When the temperature of the outdoor heating bulb is not less than the temperature threshold or fluctuates around the temperature threshold, the temperature of the outdoor heating bulb is re-evaluated to determine whether it is stable relative to the preset temperature threshold. If the result remains unchanged, a start command is sent to confirm that the unit is in start-up operation state.

[0031] As an example, when the indirect evaporative cooling COP data is less than 4, determining whether the outdoor wet-bulb temperature is stable relative to a preset temperature threshold includes: When the indirect evaporative cooling COP data is less than 4, determine whether the outdoor temperature bulb temperature is less than 25°C for a continuous period of 10 minutes.

[0032] When the COP data of indirect evaporative cooling is less than 4, and the outdoor wet-bulb temperature is less than or equal to 25℃ (can be changed), a conditional judgment is made. If the outdoor wet-bulb temperature is less than 25℃ for 10 minutes (the delay is to prevent large fluctuations in the outdoor wet-bulb temperature, sometimes greater than 25℃ and sometimes less than 25℃, to avoid the program issuing start and stop commands multiple times), a comparison is made again. If the outdoor wet-bulb temperature is less than or equal to 25℃, the program issues a start command and the unit starts running. If the temperature is greater than 25℃, the program will continuously issue a stop command and the unit will remain in standby mode.

[0033] It also includes: when the temperature of the outdoor heating bulb is greater than a preset temperature threshold, issuing a shutdown command to ensure that the unit remains in standby mode.

[0034] In one embodiment of the present invention, it further includes: The pPUE data is obtained by calculating the measured energy consumption data and the corresponding energy efficiency formula. The detailed data for each day is determined by the pPUE data, which includes data for each cold aisle, COP data for each chiller system, and pump efficiency data. Based on the detailed data, determine whether there are any abnormalities in the environmental monitoring room. If an abnormality is found, issue an alarm.

[0035] The step of calculating pPUE data using measured energy consumption data and corresponding energy efficiency formulas includes: By measuring the energy consumption of the precision air conditioner and using the calculation formula: [(actual fan speed / rated fan speed) 3 * total rated fan power] + energy consumption of the precision air conditioner, the power data of the precision air conditioner is obtained. The total rated fan power is the sum of the power of the total number of fans. The standby power data of the precision air conditioner was obtained through measurement. Transformer loss data can be obtained using the formula: Input power of front-end transformer - Output power of transformer. The UPS loss data can be obtained using the formula: Front-end UPS input power - UPS output power; The transformer efficiency data can be obtained using the formula: (Transformer output power / Transformer front-end input power) * 100; The UPS efficiency can be obtained using the formula: (UPS output power / UPS front-end input power) * 100.

[0036] It should be noted that PUE (Power Usage Effectiveness) is a comprehensive indicator widely accepted and adopted by data centers both domestically and internationally to measure the energy efficiency of data center infrastructure. Its calculation formula is: PUE = PTotal / PIT. Where PTotal is the total power consumption of the data center, and PIT is the power consumption of IT equipment within the data center.

[0037] The practical meaning of PUE (Power Usage Effectiveness) refers to the percentage of total electrical energy supplied to a data center that is actually used by IT equipment. PUE data ranges from 1.0 to infinity. A higher PUE value for a data center indicates greater energy consumption by its supporting infrastructure, such as cooling and power supply. PUE is simple to define and easy to calculate; by measuring both the total power consumption of the data center and the power consumption of IT equipment, the PUE of the entire data center can be calculated immediately.

[0038] Total power consumption in a data center includes all electricity used to maintain its normal operation, including IT equipment, cooling equipment, power distribution systems, and other facilities. If the building housing the data center is also used for other purposes such as offices, the electricity consumed by these purposes is not included in the total power consumption of the data center. Within a data center, only the power consumption of IT equipment is considered "meaningful" energy that generates effective output.

[0039] pPUE (Partial PUE) is an extension of the data center PUE concept, used to assess and analyze the energy efficiency of specific areas or equipment within a data center.

[0040] When using the pPUE metric to evaluate the energy efficiency of a data center, the first step is to divide the data center into different zones as needed. A server room in a multi-story data center building, or a container module in a containerized data center, can be considered a zone.

[0041] Partial PUE reflects the energy efficiency of a portion of a data center's equipment or area, and its value may be higher or lower than the overall PUE. To improve the overall energy efficiency of a data center, it is generally necessary to first improve the energy efficiency of the equipment or area with the higher pPUE. Partial PUE is suitable for assessing the partial energy efficiency of modular data centers built on containers or other modular units, or larger data centers consisting of multiple buildings and server rooms.

[0042] As an example, after all the data is calculated, the pPUE between different computer rooms can be compared, down to the comparison between each cold aisle, the COP between chillers, the pump efficiency, and daily data comparison. Any anomalies can be detected promptly (providing environmental alarm prompts). For instance, when an anomaly occurs in an indirect evaporative chiller, the unit's COP can be reflected immediately, allowing data personnel to handle it promptly. Compared to existing environmental monitoring rooms, where environmental monitoring is difficult to detect, resulting in continuous unit operation and energy waste, this application can promptly detect anomalies and provide environmental alarm prompts, which is beneficial for energy conservation in environmental monitoring rooms.

[0043] If a single server room has a normal IT power consumption of 500KW and a HVAC power consumption of 20KW, with a pPUE of 4%, we can determine if there is potential energy waste if it exceeds 4%, and immediately intervene manually. This could be due to issues such as cold aisle doors not being properly closed, blind flanges not being sealed, or air conditioning not slowing down after server traffic has stopped. pPUE can be broken down to the cold aisle level for each server room, effectively preventing energy waste and reducing overall server room energy consumption. Through pPUE, we can monitor the real-time status of each server room and each server room's cold aisle, and if any abnormalities are detected, the environmental monitoring system will issue an alarm, allowing on-duty personnel to handle the situation promptly.

[0044] The automatic start-up and shutdown control of the indirect evaporative cooling system in this application realizes the linkage control of the HVAC system, which can enable the indirect evaporative cooling system to achieve the optimal operating mode and reduce the energy consumption of the computer room.

[0045] This application can connect all the individual points collected by environmental monitoring into a whole through logical calculations, monitor the overall operating status of the equipment in real time, and implement linkage control through the calculated data, which can effectively reduce the energy consumption of the computer room (reduce PUE) and improve the life of the equipment.
