Description

Technical Field

[0001] This invention belongs to the field of thermal management technology, and specifically relates to a thermal management system and thermal management method. Background Technology

[0002] In related technologies, the thermal management and energy-saving renovation of old communication equipment buildings faces objective conditions such as fixed building structure, rigid business operation, and inability to carry out large-scale renovations. The optimization of thermal management airflow in old communication equipment buildings is limited by the structural and operational characteristics of the old communication equipment buildings themselves, and the results achieved are limited. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems: The inventors recognized that communication buildings, as fundamental nodes of operator networks, operate continuously throughout the year, with air conditioning systems accounting for over 40% of energy consumption. This is especially true in many older, existing communication buildings, which suffer from enclosed building structures, outdated air conditioning systems, and uneven heat load distribution, resulting in energy consumption per unit area far exceeding that of newly built standardized data centers. The telecommunications industry has continuously promoted technological innovation and transformation practices in the field of green energy conservation, gradually forming various energy-saving transformation paths applicable to communication scenarios, covering multiple dimensions from upgrading cooling equipment, optimizing air conditioning system control, adjusting air supply organization, to intelligent operation and maintenance platforms. In the practice of energy-saving renovation of old communication buildings, due to the fixed building structure, rigid business operation, and inability to carry out large-scale renovation, the industry has gradually formed several feasible renovation technology paths, mainly including: (1) energy-saving control schemes for air conditioning systems, such as dynamically adjusting the ratio of fresh air and return air according to indoor and outdoor temperature, humidity and enthalpy conditions to optimize the air conditioning operation load; (2) heat source control schemes for local equipment, such as deploying cabinet-level fans, heat exchange units, heat pipe modules, etc. to improve heat dissipation efficiency; (3) air supply path reconstruction schemes, including underfloor air supply, duct layout, ceiling exhaust, etc. However, due to the structural and operational characteristics of old communication buildings, the technology has obvious shortcomings and is difficult to apply.

[0004] The inventors recognized that older telecommunications buildings commonly suffer from non-standard equipment layouts, high cabinet density, and a high proportion of non-standard equipment. This leads to unbalanced airflow, severe mixing of hot and cold air, and traditional air conditioning systems struggle to cover the effective cooling surface, creating localized heat islands. Existing airflow optimization products are mostly static air guides and fixed louvers—structured components lacking intelligent control capabilities linked to on-site environmental parameters, making them ill-suited to dynamic changes in IT load. Furthermore, existing air guide components are often designed for standard-sized cabinets, failing to effectively adapt to non-standard deployment environments, resulting in low deployment accuracy and poor adjustability.

[0005] The inventors also recognized that the solutions in related technologies are generally geared towards standardized data center environments, and still have significant shortcomings in terms of adaptability, deployment flexibility, and intelligent response capabilities. Most of the aforementioned solutions address issues such as cold source optimization, ventilation structure adjustment, or airflow path guidance, which can be effective under certain conditions. However, in the numerous existing buildings in the telecommunications industry, complex realities such as limited space, unalterable structures, non-standard equipment arrangements, and rigid business operations often hinder the practical implementation of most of these solutions. Particularly concerning are typical problems such as frequent hotspots and severe mixing of hot and cold air currents; the solutions in these technologies often lack targeted and localized intelligent control mechanisms, making it difficult to fundamentally improve cooling efficiency and cold capacity utilization.

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0010] The thermal management system of this invention can optimize airflow by arranging air guide devices and air wall devices without affecting the operation of existing services. The air guide devices and air wall devices of this application can be modularly arranged, have strong adaptability and flexible arrangement, and can better realize the airflow optimization system with local perception and intelligent control capabilities.

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The inventors recognized that the thermal management systems in old communication buildings in related technologies generally have the following common problems, which can be summarized into three categories: (1) Limited applicable scenarios: Many solutions rely on standardized building structures or ventilation renovation spaces, but old communication buildings are densely packed with equipment and have closed structures, making it difficult to achieve renovation conditions; (2) Rigid deployment methods: Methods such as fresh air path layout and floor duct construction all require shutdown construction or large-scale intervention, which violates the operation and maintenance principle of "7×24-hour uninterrupted operation" of communication systems; (3) Lagging control strategies: Most solutions fail to introduce environmental perception and dynamic control mechanisms, and cannot achieve regional on-demand cooling, load balancing adjustment and coordinated optimization of cold and hot flow fields. Therefore, even under conditions of significant changes in equipment heat dissipation load, existing technologies still cannot provide effective coping strategies, and problems such as cold and hot mixed flow and local hot spots are still difficult to alleviate.

[0027] Therefore, embodiments of the present invention propose a thermal management system and thermal management method with good cooling distribution effect and good thermal management performance.

[0028] See Figures 1-3 The thermal management system of this invention includes an air guide device 1 and an air wall device 2. The air guide device 1 and the air wall device 2 are located inside a communication building. The air guide device 1 includes multiple air guide components, with adjacent air guide components joined together to guide the flow of cold air. The air guide device 1 can guide the flow of cold air from the air conditioning duct 3, allowing the cold air to be delivered more concentratedly to the vicinity of the server rack 4. Especially when the inside of the server rack 4 is not enclosed, more cold air can enter the server rack 4, improving the cooling effect of the cold air on the electrical components inside the server rack 4 and increasing the utilization rate of the cold air.

[0029] The airflow control device 2 includes multiple airflow control components 21. Each airflow control component 21 has an air outlet 212 and an air damper 213. The air damper 213 controls the opening of the air outlet 212. The airflow control components 21 are used to adjust the airflow state at their location to work with the air guide device 1 to regulate the distribution of cool air in the communication building. For example, a fan is arranged inside the airflow control component 21 to blow out air, and the air damper 213 controls the size of the opening of the air outlet 212. This can adjust the airflow distribution at the location of the airflow control component 21, prevent hot air from returning to the front channel, and increase the residence time of cool air, thereby achieving thermal management of specific areas and specific points.

[0030] This embodiment, through the cooperation of the air guide device 1 and the air wall device 2, not only achieves the guidance of a large flow of cold air, making the cold air distribution in the communication building more uniform and consistent, but also uses the air control component 21 to adjust the airflow state in the cold and hot air convergence area or typical hot spot area, avoiding local heat accumulation, ensuring that the airflow can flow fully, optimizing the flow path of cold and hot air, avoiding mutual interference, improving the consistency of indoor temperature, and improving the cooling effect on the electrical components in the cabinet 4.

[0031] The thermal management system of this invention requires no demolition or modification of the original cabinets, ceiling, or floor structure during deployment, possessing high adaptability and engineering feasibility. Without affecting existing business operations, airflow optimization can be achieved by arranging air guide devices 1 and air wall devices 2. The air guide devices 1 and air wall devices 2 of this application can be modularly arranged, exhibiting strong adaptability and flexible deployment. This allows for a better realization of an airflow optimization system with local sensing and intelligent control capabilities, providing a superior thermal management solution for the green energy-saving renovation of existing communication buildings, demonstrating good practicality. The system as a whole, through the coordinated operation of structural air guidance and intelligent control, significantly improves cooling efficiency, reduces the risk of localized overheating, and achieves a systematic improvement in the operational energy efficiency of old communication buildings.

[0032] In some embodiments, the air guide assembly includes an air guide frame body 111, an adjusting member 112, and a connecting portion 113. The adjusting member 112 is disposed on at least one side of the air guide frame body 111 in the circumferential direction, the adjusting member 112 is connected to the air guide frame body 111, and the adjusting member 112 is movable relative to the air guide frame body 111; the connecting portion 113 is disposed in the circumferential direction of the air guide frame body 111 and / or the circumferential direction of the adjusting member 112, and two adjacent air guide assemblies are connected by the connecting portion 113.

[0033] The air guide frame body 111 is the main structure of the air guide assembly. The adjustment component 112 can be located on one side of the air guide frame body 111, for example, the right side of the air guide frame body 111 shown in the figure. This allows adjustment of the distance between the two edges of the air guide assembly in the left and right directions, facilitating the connection between the air guide assemblies and enabling them to adapt to different types of communication equipment cabinets 4 and computer room structures, thus improving deployment flexibility.

[0034] Because the rack models inside old server rooms vary and are not standardized, the spacing between adjacent racks also differs. If the size of the air guide components cannot be adjusted, multiple air guide components will often be spliced ​​together and will not match the structure of the racks and server room, failing to guide the cold airflow to the racks effectively and affecting the cooling effect.

[0035] The adjusting component 112 includes an end plate and a circumferential side plate located on the end plate. A portion of the adjusting component 112 can be sleeved together with the air guide duct body, thereby maintaining the stability and sealing of the connection between the air guide frame body 111 and the adjusting component 112 when the adjusting component 112 moves. Alternatively, one of the adjusting component 112 and the air guide frame body 111 is provided with a slide rail 114, and the other is provided with a slider. The slide rail 114 and the slider slide in cooperation to allow the adjusting component 112 to move relative to the air guide frame body 111. The slide rail 114 can be provided on the edge of the air guide frame body 111, and the slider can be provided on the adjusting component 112. When moving, the slider moves within the slide rail 114 to ensure parallelism between the two and prevent the adjusting component 112 from disengaging from the air guide frame body 111.

[0036] Of course, after the adjusting component 112 is moved into place, it can be secured by a snap fastener or fastener to prevent the adjusting component 112 and the air guide frame body 111 from moving relative to each other again.

[0037] This invention addresses the problems of chaotic airflow, severe mixing of hot and cold air, high energy consumption, and low heat dissipation efficiency caused by complex cabinet layouts and irregular spaces in old communication equipment rooms. It proposes an airflow optimization and energy-saving system that can be quickly deployed without dismantling or modifying existing servers, integrating structural optimization and intelligent control. The system consists of two parts working together: a modular air guide device 1 and a local intelligent airflow wall device 2. Its aim is to achieve effective separation and dynamic control of hot and cold airflow, thereby improving the overall energy efficiency of the equipment room.

[0038] Furthermore, the air guide assembly also includes a sealing component 115, which is disposed at the connection between two adjacent air guide assemblies to seal the gap between the two adjacent air guide assemblies. The sealing component 115 can be a sealing strip, for example, made of high-elasticity silicone or polyurethane foam, thereby ensuring a sealed air guide path, preventing cold air leakage or hot air backflow, and improving the utilization rate of cold air.

[0039] In this embodiment, the circumferential side lengths of the air guide frame body 111 orthogonal to its thickness direction are the same. That is, the cross-section of the air guide frame body 111 orthogonal to its thickness direction is generally positive, facilitating assembly. The adjusting component 112 can typically be completely retracted within the air guide frame body 111. When adjustment is needed, a portion of the adjusting component 112 is pulled out without affecting the overall stability of the air guide frame body 111. Alternatively, the air guide frame body 111 and the adjusting component 112 can be detachable. When the size of the air guide frame body 111 needs adjustment, the adjusting component 112 is assembled onto the air guide frame body 111 for size adjustment, offering high flexibility and practicality. The circumferential side length of one part of the multiple air guide components is n times the circumferential side length of another part, where n is an integer. n can be 2, 3, 4, etc. For example, the air guide components have multiple specifications, one being 600mm*600mm and another being 300mm*300mm. During assembly, different quantities of two specifications of air guide components can be selected and spliced ​​together according to requirements.

[0040] The maximum adjustment stroke of the adjusting component 112 is 50mm to 200mm. Specifically, the maximum adjustment stroke of the adjusting component 112 is 50mm, 60mm, 85mm, 100mm, 125mm, 155mm, or 200mm. For example, if the maximum adjustment stroke of the adjusting component 112 is 50mm, and the initial dimension of the air guide assembly in the left-right direction is 600mm, the dimension of the air guide assembly in the left-right direction can be 600mm after the adjusting component 112 is fully retracted into the air guide frame body 111, and the dimension of the air guide assembly in the left-right direction can be 650mm when the adjusting component 112 is extended to its maximum stroke.

[0041] For example, the adjusting component 112 is part of the air guide frame body 111. The adjusting component 112 has an initial state, a retracted state, and an extended state. In the initial state, the air guide frame body 111 has a dimension of 600mm in the left and right direction. When the adjusting component 112 moves from the initial state to the limit position of the retracted state, the air guide frame body 111 has a dimension of 550mm in the left and right direction. When the adjusting component 112 moves from the initial state to the limit position of the extended state, the air guide frame body 111 has a dimension of 650mm in the left and right direction.

[0042] The adjustment accuracy of this embodiment can reach 1mm, which meets the adaptation requirements of complex environments such as non-standard cabinet spacing and cabling obstacles.

[0043] The air guide device 1 in this embodiment can be made of aluminum alloy to form a standardized unit module, which facilitates production and processing.

[0044] In this embodiment, the connecting part 113 can be a mounting groove or mounting boss provided in the circumferential direction of the air guide frame body 111 and / or the circumferential direction of the adjusting component 112. When two adjacent air guide components are assembled, the mounting boss in one air guide component is embedded in the mounting groove of the other air guide component, thereby achieving quick connection and avoiding air leakage, which is practical.

[0045] Optionally, two adjacent air guide components can be connected by magnetic attraction, snap-fit ​​connection, fastener connection, or adhesive bonding. The connection structure offers diverse forms, good practicality, and convenient operation, greatly improving assembly efficiency. It enables rapid on-site installation and non-destructive dismantling, providing greater adaptability to site space and high deployment flexibility.

[0046] In this embodiment, the air guide device 1 can be installed on the top or side of the cabinet 4 in the communication building. Depending on the distribution characteristics of the cabinets 4 in the communication building and the size of the gap between adjacent cabinets 4, the air guide device 1 can be flexibly arranged in the space on the top of the cabinet 4 or in the gap on the side of the cabinet 4, so as to deploy an airflow path in the room that facilitates the flow of cold air and improves the heat exchange effect of the cabinet 4.

[0047] The modular air guide device 1 in this embodiment adopts a standard unitized structure and quick-installation connection method, and has multiple adaptation mechanisms such as splicing, extension, and sealing, making it suitable for non-standard cabinet 4 layout scenarios with different heights and spacings. This device guides cold air to the air inlet surface through top, side, or front air guiding methods, while blocking the backflow of hot air, thus constructing a quasi-hot and cold aisle structure.

[0048] In this embodiment, the edges of the air guide assembly are closed. The structural closure and physical support for the module splicing ends are achieved through end limiting structures, edge chamfering structures, and right-angle splicing structures, which prevents structural deformation and improves structural stability.

[0049] In some embodiments, the air control assembly 21 includes a housing 211, a driver, and a controller 215. An air vent 212 is located on at least one side of the housing 211, and a damper 213 is located at the air vent 212 to open or close it. The driver controls the movement of the damper 213. The damper 213 can be a louvered damper 213, with the blades opening from 0 to 90 degrees, thereby effectively adjusting the direction and opening of the airflow, offering good practicality. The driver can be a motor, which drives the shaft of the louvered damper 213 to rotate, thereby achieving the oscillation of the blades in the louvered damper 213. In this embodiment, the housing 211 can be generally cubic in shape. The controller 215 can be used to control the driver's operation based on control signals.

[0050] The air control component 21 in this embodiment also includes a detection component 214, which is disposed on the outer shell 211. The detection component 214 is used to detect the circumferential environmental parameter information of the air control component 21. The environmental parameter information includes at least one of temperature, humidity and airflow speed. The detection component 214 can be a temperature sensor, humidity sensor, wind speed sensor, etc. The environmental parameter information detected by the detection component 214 can be further analyzed and judged by the controller 215, thereby issuing control signals to control the action of the driver and achieve airflow adjustment at the corresponding location. The airflow control assembly 21 also includes a communication module, which can be integrated into the controller 215. Multiple airflow control assemblies 21 in the air wall device 2 can be stacked vertically, thereby achieving fine-tuning of the vertical hot and cold airflow distribution through the opening and closing of the air vents 212 of the airflow control assembly 21. The multiple airflow control assemblies 21 operate independently without affecting each other, improving response efficiency and thermal management performance.

[0051] When the air control components 21 are arranged in the convergence zone of hot and cold air currents or in typical hot spot areas, each air control component 21 can be numbered to achieve individual control of the dampers 213 within each component. This allows for control of airflow interruption in specific areas, preventing hot air from returning to the front channel or increasing the residence time of cold air. Temperature, humidity, and wind speed sensors serve as environmental sensing units, including integrated temperature and humidity sensors and wind speed sensors. These sensors are installed on the front or sides of the air wall to collect real-time data on the local thermal environment and airflow status. The controller 215 integrates a microprocessor chip, data interface, and communication module. It receives sensor data, determines whether local heat accumulation occurs, and sends control signals to adjust the angle of the dampers 213 accordingly. Each air control component 21 is a relatively independent working unit, and its deployment quantity and location can be set as needed. For example, based on the height of the cabinet 4, multiple air control components 21 can be arranged vertically to form an air wall device 2 in that area, enabling precise response control for hot spots. The module has power independence and communication address allocation capabilities, facilitating distributed deployment and unified management within the system.

[0052] In this embodiment, the outer casing 211 is equipped with a display screen 216 and a control panel 217. The display screen 216 can display environmental parameters such as temperature, humidity, and wind speed of the corresponding area, so that staff can intuitively observe the temperature differences between different areas. The control panel 217 can be a button or a touch panel, which assists staff in adjusting and setting corresponding parameters on-site, so as to make timely adjustments according to the on-site conditions and improve debugging efficiency.

[0053] Furthermore, the air control assembly 21 also includes a protection module connected to the detection component 214 and the actuator. This protection module controls the actuator to close the air vent 212 when the temperature detected by the detection component 214 exceeds a first temperature threshold. The first temperature threshold can be set to 65 degrees Celsius, 70 degrees Celsius, or 80 degrees Celsius, etc. In this embodiment, the protection module can automatically close the air vent 212 after the local temperature exceeds the corresponding temperature threshold, meeting the needs of fire alarm linkage and improving the safety of system operation.

[0054] This invention proposes an innovative energy-saving solution for the complex environment of old communication buildings, which has the following features: (1) Modular structure and strong adaptability, which can be flexibly deployed between non-standard cabinets, on the top or side space to realize the construction of quasi-hot and cold aisles. (2) Intelligent control and real-time response, which can automatically adjust the airflow path according to local temperature, humidity and wind speed changes to achieve local adjustment rather than global intervention. (3) Low-intrusion deployment and uninterrupted service, which can complete the deployment and upgrade through non-shutdown and quick-installation components, shortening the transformation cycle and reducing construction costs. This embodiment is a new type of energy-saving system with structural flexibility, self-sensing ability and intelligent adjustment function, which proposes a highly reliable thermal management solution for the green upgrade of old communication buildings.

[0055] The modular air guide device 1 adopts a splicable and adjustable structural design, supporting flexible installation of the front, top, or side air guide components 11, and can adapt to the messy rack arrangements of different heights and spacings. Its structure includes a magnetic or snap-on quick-installation mechanism, which facilitates rapid on-site assembly and adjustment; the flexible sealing component 115 can effectively reduce airflow leakage and improve the hot and cold aisle isolation effect; the adjustable component 112 can be finely adjusted in height and width according to the actual rack layout 4, ensuring that the device fits tightly with the rack 4, thereby creating a quasi-hot and cold aisle environment and significantly reducing the mixing of hot and cold airflows.

[0056] The controller 215 in this embodiment has data acquisition, threshold judgment, and command output functions. It can judge the acquired data based on the set strategy and control the electric damper 213 to respond to opening and closing. The air control component 21 is equipped with a communication interface with the upper computer room BMS or air conditioning system (supporting RS-485 / Modbus or BACnet protocol) to receive strategy commands or feedback on the operating status. The damper 213 has an independent fuse protection module embedded in its structure. When the detected temperature exceeds 70°C, it automatically closes the air duct to meet the fire linkage requirements and enhance the safety of system operation. The entire air wall device 2 supports quick installation and has independent power supply, independent addressing and distributed deployment capabilities, which are suitable for distributed intelligent regulation in multi-point heterogeneous thermal environments.

[0057] A locally intelligent air wall device 2 is deployed at a hot-cold air flow intersection area or a local hot spot position, integrates a temperature and humidity sensor, an electric damper and a microcontroller 215, and has environment sensing and linkage adjustment capabilities. The system dynamically adjusts the opening and closing state of the damper 213 by collecting real-time temperature and wind speed data in combination with a preset control logic, so as to achieve accurate isolation of hot and cold air flows and suppression of hot spots. Meanwhile, the air wall module is provided with a linkage interface for connection with a fire fighting system, ensuring that the air duct can be automatically closed in an emergency to improve system safety. This embodiment achieves dynamic response to local air flow states, has functions such as linkage regulation and strategy following, and has good practicability and high safety.

[0058] The cooperative work of the air guiding device 1 and the air wall device 2 realizes optimization of hot and cold air flow paths and adaptive adjustment of energy saving strategies through a unified control platform, supports data linkage with a computer room BMS system or an air conditioning system to form closed-loop control and improve overall operation efficiency. The system is suitable for the arrangement scenario of non-standard cabinets 4, has strong compatibility and engineering implementability, can be rapidly deployed without interrupting communication services, has short construction period and low cost, and has remarkable energy saving benefits and engineering practical values.

[0059] In some embodiments, there are a plurality of air wall devices 2 and a plurality of air guiding devices 1.

[0060] Refer to Figure 4 , the thermal management method according to an embodiment of the present invention uses the thermal management system described in any one of the above items to perform environment regulation, and the thermal management method includes:

[0061] S1, acquiring environment parameter information of a target area, and preprocessing the environment parameter information. The environment parameter information may include one or more of temperature, humidity and wind speed. Specifically, preprocessing the environment parameter information includes: performing moving average processing on the environment parameter information to smooth instantaneous fluctuation data, performing outlier elimination processing on the environment parameter information to remove abnormal values, and performing unified dimension standardization processing on the environment parameter information, thereby improving the reliability of the environment parameter information and improving the accuracy and practicability of thermal management.

[0062] S2, analyzing the environment parameter information to generate a control instruction. After analyzing the environment parameter information by a controller, whether it is necessary to adjust the air flow state of the corresponding target area and the adjustment amplitude are determined.

[0063] S3, adjusting the opening degree of the damper 213 of at least part of the wind control assemblies 21 based on the control instruction. Thereby, the air flow state of the target area can be accurately adjusted, heat accumulation in the area is avoided, the cooling effect of cabinets in the area is improved, and accurate adjustment and control of thermal management are realized.

[0065] S5. If not, repeat the above steps. When parameters such as temperature, humidity, and wind speed do not meet the preset values, repeat the adjustment.

[0066] S6. If yes, determine whether to update the preset values ​​of the environmental parameters of the target area. If not, end the adjustment.

[0067] S7. If so, repeat steps S1 to S6. If the load on the rack changes or a new adjustment strategy is adopted, repeat the above steps to perform a new round of adjustments.

[0068] Specifically, this embodiment operates around a closed-loop logic of "sensing-control-regulation-feedback." By deploying modular air-guiding devices and locally intelligent airflow barriers within the equipment room of the communication building, it achieves the reconstruction of hot and cold airflow paths and dynamic control of the local thermal environment. The system collects local environmental conditions in real time through temperature, humidity, and wind speed sensors. The controller comprehensively analyzes and adjusts the opening of the airflow barriers to optimize the cold air delivery path, alleviate local overheating problems, and automatically adjusts strategies and provides energy-saving responses based on the operating status, thus constructing an environmental optimization system that combines intelligence, adaptability, and energy efficiency.

[0069] Specifically, the system operation follows a path of "sampling—transmission—control—execution—feedback" to achieve continuous dynamic optimization of the local microenvironment. At the initial stage of system operation, the detection unit collects parameters such as temperature, humidity, and wind speed in the target area in real time. The collected data first enters the control unit for preprocessing. The preprocessing includes moving average processing to smooth instantaneous fluctuations, outlier removal to eliminate abnormal value interference, and standardization processing to improve the stability and consistency of control decisions.

[0070] The pre-processed data is centrally analyzed by the controller, which generates control commands to drive the opening adjustment of the electric damper. The damper's action enhances the efficiency of cold air delivery or blocks the recirculation of hot air by changing the airflow path and velocity in a local area. After adjustment, the controller continuously samples the environmental status and determines whether the current temperature and wind speed have returned to the set target range. If the set range has not been reached, the system will continue to sample and reissue adjustment commands, forming a stable adaptive closed-loop adjustment process. In several consecutive cycles, if the system determines that the current regional environment has been stably maintained within the target range, the controller will further determine whether there is a need to update the strategy target. For example, when the load decreases at night or a new strategy command is received from the BMS system, the controller can dynamically adjust the current control target, such as appropriately widening the temperature control range or reducing the wind speed target, thereby entering an energy-saving operation state. If no update is required, the system maintains the existing operating logic and continues to execute the environmental maintenance and inspection mechanism.

[0071] Through this collaborative logic, the airflow control system can continuously sense and respond to the local thermal environment, achieving intelligent energy-saving goals while ensuring temperature control accuracy. The system structure features modular independence and adaptive control capabilities, allowing for flexible adaptation to multi-area distributed deployments in complex thermal environments during data center renovations. It is particularly suitable for scenarios in older communication buildings where localized hotspots are frequent and cold airflow organization is disordered, providing an engineering-ready system solution for improving cooling efficiency and reducing energy consumption.

[0072] In applications, air guide devices are deployed between non-standard cabinets, on top, or in side spaces. Through a splicing structure, they form closed or semi-closed air guide channels in the communication equipment room to guide the concentrated flow of cold air to the front door area of ​​the cabinet, while preventing hot air from flowing back to the cold area, thus achieving a "quasi-cold and hot aisle" layout. Locally intelligent air wall devices are deployed at the end of the air guide path or at the junction of cold and hot air to control and regulate the airflow at both ends of the channel. When heat load accumulation or air supply efficiency is detected, the dampers are automatically opened or closed to adjust the airflow interruption status. The entire system operates based on a closed-loop control process of environmental perception, state judgment, and control execution. The air guide structure is responsible for basic path construction and cold air containment, while the air wall module is responsible for dynamic adjustment and hotspot response. The two form a collaborative mechanism between physical structure and intelligent control. The controller can dynamically adjust target parameters according to the set strategy and instructions issued by the BMS system to achieve on-demand cooling, zone response, and time-based energy-saving mode switching. While maintaining cooling capacity delivery efficiency and temperature control stability, the system can dynamically balance system energy efficiency and control load through delay adjustment, control cycle optimization, and zone priority configuration to achieve a highly adaptable energy-saving operation strategy.

[0073] The system design of this invention fully considers the common non-standard cabinet layout characteristics in old communication buildings, including: inconsistent cabinet heights, unequal spacing, irregular arrangement, lateral equipment insertion, and cable interference; the modular air guide assembly adopts a layout combining standard units and adjustable structures, assembled by splicing units of different sizes (such as 300mm and 600mm), combined with ±50mm... The sliding rail adjustment mechanism and flexible sealing components enable adaptability to complex spacing and spatial heights; the air wall device has independent working capability and a quick-installation interface design, allowing for flexible jump installation, insertion, or point deployment based on local hotspot distribution, eliminating the need for row-by-row installations and improving deployment accuracy and cooling capacity delivery efficiency; the system adopts a non-destructive deployment method, with a quick-installation structure supporting various forms such as magnetic suction, nano-adhesive, and clips, allowing direct installation on the top of the cabinet, between two cabinets, or on the side frame without removing the cabinet, floor, or ceiling, and without interfering with the original cable layout or air conditioning system; all components can be deployed in sections and phases without interrupting communication services, supporting rolling construction and uninterrupted service upgrade modes, significantly reducing engineering upgrade cycles and implementation costs, and improving engineering feasibility.

[0074] By constructing a cooling air path using modular air guide components and coordinating with the flow regulation of intelligent air walls, the system can achieve localized adjustment based on heat load distribution, forming a closed-loop control process of structural control + intelligent judgment + response execution. It possesses a strategy response mechanism for linkage with the BMS system: the system supports standard protocols (Modbus, BACnet) and data interface with the BMS platform, can upload operating status, receive control strategy commands, and realize functions such as strategy cascading and dynamic optimization of regional energy consumption, enhancing the system's scalability and integration capabilities. This embodiment achieves quantifiable energy-saving benefits: in classic communication building deployment tests, the system can effectively improve cooling capacity utilization, reduce the frequency of air conditioning overload operation, and significantly reduce PUE, achieving energy consumption visualization and closed-loop verification of energy-saving effects while ensuring safe equipment operation. This embodiment has high cost-effectiveness and adaptability for widespread application: the system components have high versatility, low manufacturing and installation costs, and a short deployment cycle, balancing the economic efficiency and technological advancement of renovation projects, making it suitable for large-scale distributed energy-saving renovation projects for aging communication infrastructure.

[0075] The embodiments of this invention construct an energy-saving system for communication building that integrates structural adaptation, intelligent control, engineering practicality and strategic linkage. It breaks through the bottleneck of existing technologies that are difficult to balance intelligence and low-intrusion deployment, and has significant innovation, practicality and promotion value.
