Description

Technical Field

[0001] This application relates to the field of data center technology, specifically to a data center airflow organization and control system and method. Background Technology

[0002] Data center server rooms typically employ a raised floor structure with underfloor air supply and top return. They may incorporate cold aisle or hot aisle designs. Ventilation vents are installed in the floor. Precision air conditioners cool the air and then deliver it into the cavity beneath the raised floor, from where it is distributed to the floor above the server room via the vents, thereby dissipating heat from the IT equipment.

[0003] Data center thermal management needs to avoid localized hotspots. IT equipment (such as servers and network devices) experiences significant variations in heat generation due to operational status (e.g., changes in CPU load), and the operating status of cooling fans will dynamically change accordingly. To prevent IT equipment from overheating, the temperature of the cooling air needs to be lowered, which can be achieved by increasing the number of precision air conditioners online and increasing their airflow to enhance cooling capacity.

[0004] Traditionally, server room control relies on manually adjusting the number of precision air conditioners connected, with the air conditioners automatically adjusting the airflow based on return air temperature. Since floor vents typically have fixed or manually adjustable openings, dynamic adjustment of the floor openings is usually impossible, as is precise airflow control over the area above each perforated floor panel. This conventional control method easily leads to uneven airflow within the server room, creating localized hotspots for IT equipment, and also results in high energy consumption, hindering energy conservation.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0023] Please see Figure 1 The data center airflow organization and control system provided in this application embodiment includes a data center controller, an air conditioner, an electrically adjustable ventilation floor, and a temperature sensor, wherein... The temperature sensor is used to collect real-time temperature data from various areas of the computer room and transmit the real-time temperature data to the computer room controller. The data center controller is used to receive the real-time temperature data, determine the local overheating situation in the data center based on the real-time temperature data, and dynamically adjust the on / off status and air volume of the air conditioner and the opening degree of the electrically adjustable ventilation floor according to the local overheating situation in the data center and the working status of the IT equipment.

[0024] In one optional embodiment of this application, the electrically adjustable ventilation floor consists of a perforated floor cover, a floor baffle, a drive device, sensors, etc., and can achieve stepless adjustment of the opening from 0 to 100%. Compared with fixed openings or limited manual adjustment, it can accurately match the air volume according to the actual temperature requirements, avoiding the problems of excessive air volume causing energy waste or insufficient air volume failing to effectively cool down.

[0025] In an optional embodiment of this application, the temperature sensor can be a temperature and humidity sensor, and the temperature sensor array is deployed around the IT equipment and in key locations of the cold and hot aisles, rather than relying solely on a single return air temperature detection.

By automatically controlling the number of precision air conditioners in operation, airflow intensity, and the opening size of the floor vents, it achieves precise airflow control within the data center, resolving the problem of uneven airflow.

[0027] In an optional embodiment of this application, see [link to relevant documentation]. Figure 2 The data center controller includes a computing module, an interface processing module, a communication module, a power supply module, and a display module, wherein... The calculation module is used to analyze the received real-time temperature data and the working status of IT equipment, determine whether the local area of ​​the computer room is overheated, and generate air conditioning adjustment instructions and electrically adjustable ventilation floor adjustment instructions based on the overheating situation. The interface processing module is used to output motor drive signals for multiple electrically adjustable ventilation floors, and simultaneously receive the opening status of the ventilation floors.

The interface processing module is responsible for controlling the opening of multiple electrically adjustable ventilation floors in the computer room, outputting motor drive signals for multiple electrically adjustable ventilation floors, and simultaneously receiving the opening status of the ventilation floors. The adjustable opening of the electrically adjustable ventilation floors is 0-100%, dynamically adjusting the opening of multiple electrically adjustable ventilation floors. The communication module is responsible for outputting control commands to multiple precision air conditioners and collecting their status inputs; collecting status inputs from the computer room temperature sensor array; communicating with the Data Center Management System (DCIM) to obtain real-time IT equipment load data fed back by the Power Distribution Unit (PDU); and communicating with the Data Center Management System.

The display module provides status display for each HVAC device in the computer room. The display module adopts a touchscreen design, enabling automatic control while allowing administrators to view system operating data in real time and perform manual intervention in special circumstances, balancing system automation and emergency handling capabilities. The communication module of the data center controller supports multiple communication protocols, making it compatible with different types of temperature sensors, precision air conditioners, and electrically adjustable ventilation floors. It is suitable for data center rooms of varying sizes and equipment configurations. Furthermore, it supports manual intervention for adjustments, enabling it to handle emergency scenarios such as system failures or special temperature requirements, offering high flexibility. The communication module supports multiple communication protocols including Ethernet, RS485, and serial ports, ensuring compatible communication with different types of temperature sensors, precision air conditioners, DCIM systems, and data center management systems.

[0029] In an optional embodiment of this application, determining the local overheating situation in the computer room based on the real-time temperature data includes: Set preset temperature thresholds for each region and preset continuous over-temperature time thresholds; If the real-time temperature data of the current area exceeds the temperature threshold corresponding to the current area and the continuous temperature exceedance time exceeds the preset continuous temperature exceedance time threshold, the current area is determined to be a local temperature exceedance area in the computer room.

[0030] In an optional embodiment of this application, such as Figure 3 As shown, in the precise control of air conditioning, electrically adjustable ventilation floor opening, and thus the HVAC equipment and airflow organization in the computer room, when the computer room temperature is detected to be within acceptable limits and operating stably, a normal state is displayed, and the next cycle of control begins. When the computer room temperature is detected to be continuously exceeding the limit and cannot be adjusted, an audible and visual alarm is triggered, all air conditioners are turned on, the air conditioning airflow is set to maximum, all ventilation floor openings are adjusted to 100% full, and manual operation is initiated.

[0031] In an optional embodiment of this application, such as Figure 4 As shown, the criterion for judging local continuous overheating is: preset temperature thresholds for each area, and when the real-time temperature of a certain area collected by the temperature sensor continuously exceeds the corresponding temperature threshold within a preset time period t, the area is judged as a local overheating area.

Figure 5 Based on filtering and interpolation algorithms, the temperature data of the IT equipment area in the computer room is determined according to the real-time temperature data of each area of ​​the IT equipment. The steps include: Taking a row of cabinets as an example, calculate the temperature value of each area. Let the sampling data of a certain temperature sensor be t(s,n), t(s,n-1), t(s,n-2)..., where s is the s-th sensor, n is the sampling period, T(s,n) is the calculated temperature value of the s-th sensor, T(s-1,n) is the calculated temperature value of the adjacent point above the current point, and T(s+1,n) is the calculated temperature value of the adjacent point below the current point.

[0035] The calculated T(s,n) is: T(s,n) = a t(s,n) + b T(s,n-1) + c (t(s,n-1) - t(s,n-2)) Where a, b, and c are weighting coefficients.

[0036] An IT server rack is divided into e spaces from top to bottom. The calculated temperature for each space is set as follows: TS(1,n), TS(2,n), ..., TS(e,n).

[0037] If the installation location of a certain sensor s coincides with the p-th interval in e spatial intervals, then: TS(p,n) = T(s,n).

[0038] The other es temperature calculation values ​​TS are interpolated using average interpolation. This results in e TS temperature calculation data for e spaces in a row of cabinets.

[0039] In an optional embodiment of this application, the step of dynamically adjusting the on / off status and air volume of the air conditioner according to the local overheating situation in the computer room and the working status of the IT equipment includes: Obtain the power data of each column of IT devices, and determine the total cooling power of the computer room at time n based on the power data of each column of IT devices; The number of air conditioners to be online at time n is determined based on the total cooling capacity of the computer room and the rated power of the air conditioners at time n.

[0040] In an optional embodiment of this application, the communication module of the data center controller is connected to the DCIM to obtain the PDU power data of each row of IT equipment (racks). Assuming the data center has m rows of racks, and the real-time power data of the i-th rack is P(i,n), then the total cooling power of the data center at time n is determined according to the power data of each row of IT equipment using the following expression:

[0041] Where PC(n) represents the total cooling power of the computer room at time n, and P(i,n) represents the power data of the IT equipment in the i-th column. , These are weighting coefficients. The number of air conditioners in operation at time n is determined using the following expression, based on the total cooling capacity of the computer room and the rated power of the air conditioners at time n:

[0042] Where d(n) is the number of air conditioners online at time n. The weighting factor for air conditioning is greater than 1, PC(n) is the total cooling power of the computer room at time n, r is the rated power of the air conditioner, and the ROUNDUP() function is the floor function. The following expression determines the percentage of airflow from the air conditioners, based on the power data of each IT device, the number of air conditioners online at time n, and the rated power of the air conditioners:

[0043] in, Let P(i,n) represent the percentage of airflow delivered by the air conditioner, P(i,n) represent the power data of the IT devices in the i-th column, d(n) represent the number of air conditioners connected at time n, and r represent the rated power of the air conditioner. The safety factor is a constant between 0 and 1.

[0044] The data center airflow organization and control system of this application collects temperature sensor array data in real time, uses filtering and interpolation algorithms to obtain temperature calculation data of the IT equipment area in the data center, calculates the cooling power of the air conditioner in real time, controls the number of air conditioners in operation and the air volume of the fan, calculates the opening percentage of the ventilation floor in real time, and dynamically adjusts the air volume of different areas of the entire data center to achieve dynamic and refined control of airflow organization in the data center.

[0046] In an optional embodiment of this application, the temperature-weighted value of each column of IT devices is obtained using the following expression: TA i = p TS(max) + q TS(avs) Among them, TA i Let TS(max) be the maximum value of TS(1,n), TS(2,n), ..., TS(e,n), and TS(avs) be the average value of TS(1,n), TS(2,n), ..., TS(e,n). Let p and q be the weighting coefficients. Let TS(1,n), TS(2,n), ..., TS(e,n) be the temperature of the IT equipment in the i-th column, divided into e spaces from top to bottom. The opening size of the electrically adjustable ventilation floor corresponding to the current column of IT equipment is determined using the following expression, based on the power data, total rated power of the load, and temperature weighting value of each column of IT equipment:

[0047]

[0048] in, Let P(i,n) be the opening of the electrically adjustable ventilation floor corresponding to the IT equipment in column i, where P(i,n) is the power data of the IT equipment in column i, W is the total rated power of the load, and TA is the opening of the electrically adjustable ventilation floor. i The temperature weighted value for the IT equipment in the i-th column. , .

[0049] This application's data center airflow organization and control system effectively solves the problems of uneven air supply and localized hotspots in existing technologies by dynamically and collaboratively adjusting precision air conditioners and electrically adjustable ventilation floors. This ensures that IT equipment is always in a suitable temperature environment, improving its operational stability and lifespan. The precise control method, which strengthens air supply to high-load areas and weakens air supply to low-load areas, avoids the energy waste caused by maintaining a fixed cooling intensity regardless of the area load in traditional control systems. This significantly reduces the power consumption of the data center cooling system, meeting the needs of green data center development and demonstrating significant energy-saving benefits. Compared to traditional manual adjustment of precision air conditioners, this system achieves automated and refined control of airflow organization in the data center, reducing manual operation steps and lowering management costs. It also avoids the subjectivity and errors of manual adjustments, improving the standardization and efficiency of data center cooling management.
