Description

Technical Field

[0001] This invention relates to the field of air conditioning room construction technology, and in particular to a containerized modular air conditioning room and its preparation method. Background Technology

[0002] Currently, data center air conditioning rooms are typically constructed and installed on-site. Air conditioning equipment, water pipes, ductwork, electrical components, and control systems need to be installed, connected, and debugged on-site, involving cross-disciplinary construction across equipment and piping. With the development of modular construction technology, air conditioning rooms are increasingly adopting a factory prefabrication and on-site assembly approach. This involves pre-processing some equipment or piping and transporting it to the construction site for installation, reducing on-site construction workload.

[0003] Existing modular air conditioning rooms are mostly prefabricated based on single equipment or components, with relatively limited integration between the enclosure, equipment, and pipelines. The layout of equipment and pipelines lacks unified zoning and interface standards. Water pipes, air ducts, electrical systems, and automation interfaces between modules and between modules and the main building still require significant on-site adaptation in terms of spatial positioning and connection sealing. Furthermore, the lack of continuous precision control between factory prefabrication, on-site assembly, and civil engineering connections allows positional deviations at each stage to accumulate, potentially causing interface misalignment, difficulties in module splicing, and increased on-site adjustment workload. This negatively impacts the standardization and quality stability of modular air conditioning room construction.

[0004] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a containerized modular air conditioning room and its preparation method, which is rationally designed, improves the modular integration of the air conditioning room, reduces the accumulation of positional deviations at each construction stage and the amount of on-site adjustment work.

[0010] The adjustable support assembly includes multiple adjustable steel supports, which are spaced apart between the bottom of the container body and the building foundation. The bottom of each adjustable steel support is connected to the building foundation, and the top of each adjustable steel support is connected to the bottom of the container body. The vertical adjustment stroke of the adjustable steel support is 0-50mm.

[0011] A construction method for a containerized modular air conditioning unit room includes the following steps: S1. Establish a digital model using a unified three-dimensional coordinate system based on building parameters and air conditioning system parameters. Determine the quantity, size, and partitions of the container body. Determine the design coordinates of equipment foundations, layered pipeline supports, water pipe interfaces, air duct interfaces, electrical interfaces, automatic control interfaces, the installation reference of the container body, and the building connection openings in the unified three-dimensional coordinate system. Set the factory interface pre-embedded deviation, on-site container body splicing deviation, and building connection opening deviation respectively. S2. Based on the digital model, prefabricate the container body, equipment foundation, layered pipeline support, water pipe interface, air duct interface, electrical interface, and automatic control interface in the factory. Fix the pre-embedded positioning steel plates and positioning pins of the water pipe interface, air duct interface, electrical interface, and automatic control interface with positioning fixtures. Complete the partitioned assembly of air conditioning equipment, pipeline components, and electrical control components inside the container body. S3. Measure the actual coordinates of the centers of the water pipe interface, the air duct interface, the electrical interface and the automatic control interface in the unified three-dimensional coordinate system, and adjust the position of the pre-embedded positioning steel plate until the absolute value of the factory pre-embedded deviation of each interface along the X, Y and Z directions is no greater than 2mm. Then, complete the single-unit debugging, container system joint debugging, factory testing and interface sealing protection of the air conditioning equipment in each container. S4. Based on the unified three-dimensional coordinate system, re-measure the building foundation, the installation benchmark of the container body, and the building connection opening. Repair the building connection opening where the absolute value of the deviation in any coordinate direction is greater than 5mm. Hoist the container body to the building foundation. Adjust the container body along the X direction, Y direction, and vertically using the adjustable support assembly until the absolute value of the coordinate deviation of the splicing surface of adjacent container bodies is no greater than 3mm. Then fix the container body to the building foundation. S5. Connect the water pipe interface, air duct interface, electrical interface and automatic control interface of the adjacent container boxes respectively, connect the pipeline assembly in the container box to the building pipeline at the building connection opening, and seal the position where it passes through the building wall or building floor. S6. Perform water pressure test on the water pipe interface, air leakage test on the air duct interface, insulation test on the electrical interface, communication test on the automatic control interface, and overall linkage debugging of the containerized combined air conditioning room in sequence. After completing continuous trial operation, conduct acceptance.

[0012] In step S1, the digital model includes a building model, a structural model, a heating, ventilation, air conditioning (HVAC) model, a water supply and drainage model, an electrical model, a fire protection model, and an automatic control model. The origin and three coordinate axes of the unified three-dimensional coordinate system are determined by the intersection of the building structural axes and the building elevation reference point. The three-dimensional coordinates of the positioning point of the container body, the center point of the water pipe interface, the air duct interface, the electrical interface, the center point of the automatic control interface, and the center point of the building connection opening are output respectively. The factory interface pre-embedded deviation is set to ±2mm, the on-site container body splicing deviation is set to ±3mm, and the building connection opening deviation is set to ±5mm.

[0013] In step S2, the frame and load-bearing reinforcing ribs of the container body are welded sequentially; the equipment foundation and the layered pipeline support are welded; the air conditioning unit and water pump in the air conditioning equipment are installed; the prefabricated sections of the water pipes and air ducts in the pipeline assembly are connected; the cable tray in the pipeline assembly is installed; the distribution box, instruments, sensors and switches in the electrical control assembly are installed; and the electrical interface and the automatic control interface are installed. In step S3, the center coordinates of the water pipe interface, the air duct interface, the electrical interface and the automatic control interface are remeasured using a coordinate measuring machine. When the absolute value of the deviation in any coordinate direction is greater than 2mm, the pre-embedded positioning steel plate corresponding to the interface with the excessive deviation is cut, and the pre-embedded positioning steel plate is repositioned and fixed according to the positioning fixture until the remeasurement is qualified. After the factory inspection, sealing parts are installed on the water pipe interface and the air duct interface, a protective cover is installed on the electrical interface and a moisture-proof protective cap is installed on the automatic control interface.

[0014] In step S4, the three-dimensional coordinates of the center point of the building connection opening and the positioning point of the container body are measured by a total station, and the horizontality and verticality of the container body are measured by a laser level. The measured actual coordinates are compared with the design coordinates determined in step S1 in the X, Y and Z directions. Before hoisting, the building connection openings with an absolute deviation of more than 5 mm in any coordinate direction are repaired and re-measured. After hoisting, the container body and adjustable steel support are moved along the X and Y directions to adjust the horizontal position of the container body, and the support height of the adjustable steel support is adjusted to adjust the height of the container body. After the absolute deviation of the splicing surface coordinates is not greater than 3 mm, the adjustable steel support is locked and fixed to the building foundation and the bottom of the container body respectively.

[0015] In step S5, after the water pipe interface is aligned by the positioning pin, a heat-resistant rubber sealing gasket is placed between the two flanges, and the anti-loosening bolts are tightened by a torque wrench. After the duct interface is aligned with the positioning pin, a flame-retardant rubber sealing ring is pressed between the two flanges. The electrical interface is inserted and locked along the guide groove, and then fitted with a waterproof and dustproof sleeve; the automatic control interface is then connected to the switch. The size of the building connection opening is 50-100mm larger than the outer diameter of the building pipeline passing through the building connection opening. A sleeve with a waterproof wing ring is installed inside the building connection opening, and fireproof sealant is installed between the sleeve and the building pipeline. The continuous trial run time in step S6 shall not be less than 72 hours.

[0016] The beneficial effects of this invention are as follows: The containerized modular air conditioning room and its construction method provided by this invention integrate air conditioning equipment, pipeline components, and electrical control components into the container body in advance, and divide the interior of the container into an equipment area, a pipeline integration area, and an operation and maintenance area. This allows the equipment and different professional pipelines to be arranged in predetermined positions. With the help of equipment foundations and layered pipeline supports, it is beneficial to improve the regularity and modular integration of the internal layout of the room, and reserve corresponding space for equipment operation and later maintenance. By setting water pipe interfaces, air duct interfaces, electrical interfaces, and automatic control interfaces on the splicing side of the container body, the interface positions and connection forms between different modules are standardized, so that adjacent containers can be spliced ​​and connected according to predetermined interface relationships, reducing the work of readjusting and adapting the interface positions on site. Furthermore, this invention employs a unified three-dimensional coordinate system throughout the design, factory prefabrication, and on-site installation stages. This system allows for the corresponding positioning of the container, various interfaces, installation benchmarks, and building connection points. Precision re-measurement and deviation control are performed at each stage of factory prefabrication, on-site assembly, and building connection. The adjustable support structure at the bottom of the container allows for adjustments to the on-site installation position, thereby reducing interface misalignment and difficulties in container assembly caused by the gradual accumulation of positional errors at different construction stages. Simultaneously, the main assembly work of the container, equipment, and pipelines is moved to the factory for completion, with corresponding testing and debugging performed before delivery. On-site work mainly involves container positioning, module assembly, interface connection, and overall debugging. This helps reduce the workload of cross-installation and adjustments on-site, improving the standardization and installation quality stability of the containerized combined air conditioning unit construction process.

[0032] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0033] See Figures 1 to 14As shown, this embodiment is a containerized modular air conditioning room and its preparation method. This embodiment uses at least two container bodies 1 joined together to form a modular air conditioning room as an example. Each container body 1 houses air conditioning equipment 2, pipeline components 3, and electrical control components 4. The interior of the container is divided into an equipment area, a pipeline integration area, and an operation and maintenance area according to usage requirements. The equipment area is located in the middle of the container. The air conditioning equipment 2 includes an air conditioning unit 21, which is installed on an equipment foundation 23 with shock-absorbing pads at the bottom. The equipment foundation 23 is set on the load-bearing reinforcing rib plate 11 at the bottom of the container, with a height of 150mm, and is fully welded to the bottom plate of the container. Bolt holes are reserved at the equipment connection positions, and the load-bearing parameters are entered into the BIM model. A clearance of not less than 800mm is maintained between the air conditioning unit 21 and the inner wall of the container for equipment hoisting and replacement. Piping assembly 3 includes water pipes 31, air ducts 32, and cable trays. The pipeline integration area is located on the top and sides of the enclosure. Water pipes 31, air ducts 32, and cable trays are respectively installed on layered pipeline supports 34 on different levels. The layered pipeline supports 34 use channel steel supports and are welded to the side wall frame and top plate frame. The typical layer spacing is 350mm. The elevation of each layer, pipeline slope, and support spacing are consistent with the BIM model, and no holes are drilled on the back of the enclosure for fixing on site. Electrical control assembly 4 includes distribution boxes, PLCs, instruments, sensors, and switches, and is centrally located in an independent enclosed electrical compartment on the side of the enclosure. The operation and maintenance area is located on one side of the equipment area and forms a through maintenance passage along the length of the enclosure. The clear width of the passage is not less than 1200mm, and maintenance doors 15 are installed at the corresponding positions of the passage. The width of maintenance doors 15 is not less than 1000mm. Louvered ventilation openings 12 are installed on the upper sides of both sides of the enclosure. Airflow guide ducts welded to the enclosure frame are installed inside the louvers. The heat dissipation airflow is checked based on the equipment's heat output, with the ambient temperature of the equipment inside the enclosure not exceeding 40℃ under design conditions used as the heat dissipation check index for this embodiment. The top plate of the enclosure is designed with a slope for drainage towards the outer edge of the enclosure. The bottom plate of the enclosure has an additional 1.5% internal drainage slope, sloping towards the four corners. Water collection drains 13 are installed at the four corners to distinguish between external rainwater drainage from the top plate and internal drainage from the bottom plate. The inner and outer walls of the enclosure, the load-bearing reinforcing ribs 11, and the layered pipeline supports 34 are sequentially treated with epoxy zinc-rich primer and polyurethane topcoat for corrosion protection, with a total coating thickness of not less than 120μm. A grounding system is simultaneously installed inside the enclosure, and necessary pipeline insulation, internal lighting, and fire alarm facilities are installed at the factory stage.

[0034] On the splicing side of each container body 1, water pipe interfaces 61, air duct interfaces 62, electrical interfaces 63, and automatic control interfaces 64 are uniformly arranged. Within the same project, the pipe diameter or cross-sectional specifications, elevation, center distance, plug type, number of cores, and wiring standards of the same type of interface are consistent. Water pipe interfaces 61 adopt water pipe flange interfaces and are arranged in layers. The center distance between adjacent interfaces in the same layer is 300mm, the interface is 200mm from the splicing end face, and the clear operating space on the perimeter is not less than 200mm. A 5mm thick heat-resistant rubber sealing gasket is installed between two flanges and anti-loosening bolts are used for connection. The center coordinates of the flanges are used as the BIM positioning reference. The non-splicing prefabricated sections of water pipes 31 inside the container can use standardized quick-connect couplings according to the design, but the splicing ends of the container body uniformly use water pipe interfaces 61. Duct interface 62 is located at the top of the pipeline integration area, with its bottom edge 400mm from the top plate of the enclosure and 180mm from the splicing end face. The perimeter disassembly and assembly space is no less than 150mm. A flame-retardant rubber sealing ring is installed between the two flanges, and the four corners are aligned using locating pins and locating pin holes. Electrical interface 63 uses an aviation plug and is located at the bottom of a separately enclosed electrical compartment on the side of the enclosure. The center of the plug is 300mm from the bottom plate and 220mm from the splicing end face. The clearance on the plug-in side is no less than 180mm, and a guide groove and a waterproof and dustproof sleeve are provided on the outside. Automatic control interface 64 uses a prefabricated Ethernet connector and is located above electrical interface 63, with a vertical distance of 250mm between them. The clearance on the plug-in side of automatic control interface 64 is no less than 150mm, and a moisture-proof protective cap is provided. All four types of interfaces are positioned in the factory using pre-embedded positioning steel plates and specialized positioning fixtures. Interfaces requiring mechanical alignment are positioned using positioning pins, with the coaxiality deviation of the positioning pins controlled within 0.5mm. The applicable temperature range for the heat-resistant rubber gaskets and flame-retardant rubber sealing rings is -20℃ to 120℃. Electrical interface 63 and automatic control interface 64 are each equipped with independent waterproof sealed junction boxes, with a protection rating of IP65. Strong and weak current cable trays are physically separated within a closed electrical compartment, and electrical interface 63 and automatic control interface 64 are arranged in separate zones.

[0035] After construction begins, the following project boundary parameters are collected: building area, cooling and heating requirements, machine room operating conditions, floor height and dimensions, site conditions, hoisting opening dimensions, road height and weight restrictions, operation and maintenance inspection requirements, indoor maintenance passage width, and fire protection zones. The standardized BIM module library is then called up. The module library includes container bodies of different specifications, equipment families of different cooling capacities, standard pipeline parts, four types of interface families, and ventilation, heat dissipation, waterproofing and corrosion protection component families. Based on the boundary parameters, the number of container bodies, their outer contour dimensions, and the three types of functional zones are determined. A comprehensive BIM model was established, encompassing architecture, structure, HVAC, water supply and drainage, electrical, fire protection, and automation. A unified three-dimensional coordinate system was created using the intersection of building structural axes and building elevation benchmarks. Equipment foundations (23), layered pipeline supports (34), air conditioning units (21), water pipes (31), air ducts (32), cable trays, distribution boxes, PLCs, sensors, and four types of interfaces were embedded into the model. The X, Y, and Z design coordinates of the box installation benchmarks, the center points of each interface, and the center points of building connection openings were determined. Simultaneously, the box load verification, equipment foundation design, support layout, grounding, ventilation and heat dissipation, waterproofing and corrosion protection, and maintenance space verification were completed. During pipeline integration, the layout followed the principles of smaller pipes avoiding larger pipes, pressurized pipes avoiding unpressurized pipes, and separating low-voltage and high-voltage wiring. Hard and soft collision checks were performed on equipment and boxes, pipelines and pipelines, pipelines and equipment or box frames, module splicing interfaces, and boxes and building reserved openings. Detected conflicts were adjusted item by item and re-verified. After the detailed design is completed, the output includes module floor plans, elevations, sections, equipment location diagrams, pipeline fabrication diagrams, component details, and interface standard details. These are then reviewed by relevant personnel from design, prefabrication, construction, operation and maintenance, and equipment supply to confirm the component disassembly method, module splicing standards, module connection standards with the main building, and conditions for prefabrication, assembly, and maintenance.

[0036] In this embodiment, the deviations of factory interface pre-embedded parts, on-site box splicing parts, and main building connection openings are controlled to ±2mm, ±3mm, and ±5mm, respectively. All three stages are based on the design coordinates of the same three-dimensional coordinate system. The three-level precision control is not a simple arithmetic addition of 2mm, 3mm, and 5mm, but rather the actual coordinates are measured at each stage of factory, on-site hoisting, and civil engineering connection. These coordinates are then compared axis by axis with the same design coordinates and the measured data from the previous stage. When the subsequent actual connection exceeds the allowable fit of the flange, plug, or opening, the corresponding link is returned to adjust the box position, adjustable steel support, or building connection opening. Only after passing the adjustment can the next process be initiated, thus forming a continuous verification relationship.

[0037] Simultaneously, component data traceability rules are established. Each enclosure, equipment, interface, and pipeline component is assigned a unique 16-digit BIM code, consisting of a 2-digit project number, a 2-digit stage code, a 4-digit component type code, and an 8-digit serial number. To prevent changes in the same entity code due to stage changes, the 2-digit stage code in this embodiment indicates the initial stage of the entity's archiving. 01, 02, 03, and 04 correspond to design, factory prefabrication, on-site assembly, and operation and maintenance sources, respectively. Once an entity code is generated, it is not rewritten with the current construction stage. Subsequent design changes, processing, testing, construction, acceptance, and operation and maintenance records are all linked to the same entity code. The design stage is bound to technical parameters, drawings, and collision rectification records; the prefabrication stage is bound to processing data, raw material batches, and factory inspection reports; the construction stage is bound to hoisting coordinates, interface retesting, and test records; and the commissioning and acceptance stage is bound to continuous trial operation curves, acceptance data, and rectification records. QR codes serve as on-site reading carriers; test, acceptance, and operation and maintenance data not associated with the corresponding entity code are not included in the formal archive dataset.

[0038] During factory prefabrication, the BIM model is exported as an IFC4.0 structured file, and processing, material, and precision control data are broken down according to the factory's established data interfaces. Processing data extracts the lengths, bend angles, flange dimensions, and box-type steel plate cutting dimensions for water pipes 31 and air ducts 32. The factory's CAD / CAM software then generates processing data recognizable by CNC cutting machines, pipe bending machines, and welding equipment according to the processing equipment rules. Material data forms a BOQ list and is associated with corresponding BIM codes. Precision control data outputs the three-dimensional coordinates and allowable deviation thresholds for the four types of interfaces and synchronizes them to the factory collaboration platform. CNC machining equipment, the factory collaboration platform, on-site mobile terminals, and the intelligent operation and maintenance platform all read the same coding field. The factory platform associates production plans, bills of materials, processing progress, and quality inspection information with the BIM model and establishes a ledger between codes, components, processing equipment, and processing time. Processing data is recorded by scanning codes at each stage of the process. When pipes, steel plates, cables and electrical components are put into storage, corresponding QR code labels are affixed. Then, prefabricate water pipes 31, air ducts 32, layered pipeline supports 34, distribution boxes and cabinets, equipment foundations 23 and integrated junction boxes, and record information such as processing dimensions, anti-corrosion construction time and inspection personnel.

[0039] During container manufacturing, the container frame 1 and bottom load-bearing reinforcing ribs 11 are welded first. A coordinate measuring machine (CMM) is used to verify the overall dimensions. Then, the equipment foundation 23 and layered pipeline supports 34 are welded. The grounding system, louvered ventilation openings 12, air ducts, and water collection drains 13 are installed, and waterproofing and anti-corrosion construction are completed. Simultaneously, dimensional deviations, weld quality, and the load-bearing capacity required by the design are checked. Water pipe interfaces 61, air duct interfaces 62, electrical interfaces 63, and automatic control interfaces 64 are fixed with pre-embedded positioning steel plates using dedicated positioning molds according to BIM coordinates. After pre-embedding, a CMM is used to re-measure the center coordinates of the interfaces. If the absolute value of the deviation of any interface in any of the X, Y, or Z directions is greater than 2mm, the corresponding pre-embedded positioning steel plate is repositioned and fixed until the absolute value of the deviation in all three directions is no greater than 2mm. The re-measurement results are then associated with the corresponding BIM code. Subsequently, the integrated assembly of the enclosure was completed in the following sequence: fixing the equipment foundation 23, positioning the air conditioning unit 21, installing the layered pipeline supports 34, connecting the prefabricated sections of water pipes 31 and air ducts 32, installing the cable trays and distribution boxes, pre-burying aviation plugs and automatic control network cables, and installing instruments and sensors. After assembly, a water system pressure test, an air system air tightness test, and an electrical insulation test were conducted. Any deviations found were rectified, and then pipeline insulation, necessary interior decoration, lighting, and fire alarm device installation were completed.

[0040] Before leaving the factory, individual unit debugging of equipment such as air conditioning unit 21 was carried out, and operating parameters such as speed, pressure, temperature and flow were collected. Then, the water system, air system, electrical control system and fire protection system were jointly debugged according to the typical cooling and heating load conditions selected in the design, and Profinet or Modbus TCP communication tests were performed on the PLC and automatic control network. The interface coordinates of multiple container bodies 1 were simulated and aligned using the BIM model to verify the module splicing relationship. The water pipe interface 61, air duct interface 62, electrical interface 63 and automatic control interface 64 were re-measured. If the absolute value of the deviation exceeded 2mm, rework and adjustment were carried out. After passing the test, a module factory inspection report was generated, and the inspection data and image data were bound to the corresponding BIM code. Sealing parts were installed on water pipe interface 61 and air duct interface 62, a protective cover was installed on electrical interface 63, and a moisture-proof protective cap was installed on automatic control interface 64.

[0041] Before on-site construction, a specialized BIM site layout model consistent with the actual site scale is established. Temporary module storage areas, formal installation positions, and hoisting paths are planned according to the actual site locations. An operating space of no less than 1.5m is reserved in equipment hoisting and module adjustment areas. The main construction passage is no less than 4m wide, and the secondary construction passage is no less than 2m wide. Temporary water and electricity routes, cross-operation isolation zones, and construction time windows for each specialty are also planned. Installation benchmarks and building connection opening coordinates are sent to the on-site mobile terminal. A BIM engineer, MEP installation engineer, electrical engineer, control engineer, and fire protection engineer are deployed on-site. Equipment includes a total station, laser level, laser rangefinder, torque wrench, flange connection tools, water pressure testing equipment, air tightness testing equipment, air leakage testing equipment, multimeter, megohmmeter, and fire protection system commissioning terminal. Relevant personnel complete the corresponding professional training according to project requirements before starting work.

[0042] Finished modules are transported using flatbed trailers. Before transport, the equipment and pipelines inside the box are secured, and plastic protective covers and cushioning supports are installed at the splicing interfaces. After the modules arrive on site, on-site personnel scan the box's BIM code to retrieve factory prefabrication and factory inspection data. They then check the box's external dimensions, interface appearance, equipment status, and component codes against the model. If obvious damage to the box's appearance or deformation of the interfaces is found, the module will not proceed to the hoisting process and will be returned for processing. Before hoisting, a total station is used to verify the three-dimensional coordinates of the building foundation, the box's installation benchmark, and the building's connection openings. If the absolute value of the deviation from the design value in any coordinate direction is greater than 5mm, the building's connection opening must be repaired and remeasured. It is forbidden to rely on forcibly squeezing pipelines to complete the connection. After passing inspection, the container body 1 is hoisted to the concrete foundation by hoisting equipment. Existing adjustable steel supports are set between the bottom of each container and the building foundation. The vertical adjustment stroke of the adjustable steel supports is 0-50mm. Before the supports are finally locked, the X and Y directions are corrected by hoisting and positioning and slight horizontal movement of the container and supports. The Z direction is corrected by adjusting the height of the supports. The horizontality and verticality are checked with a laser level until the absolute value of the deviation of each coordinate direction of the splicing surface of adjacent containers is no more than 3mm. Then the supports are locked and fixed to the building foundation and the bottom of the container. The adjustment amount and the re-measured coordinates are written into the corresponding container data record.

[0043] During module assembly, the coordinates of the factory interface, the on-site splicing surface, and the building connection openings are compared again using a total station and the on-site BIM terminal. Water pipe interface 61 is aligned using the positioning structure, a 5mm heat-resistant rubber gasket is placed between the two flanges, and the anti-loosening bolts are tightened sequentially using a torque wrench according to the uniform tightening torque determined for the project. After connection, a water pressure test is performed. Air duct interface 62 is aligned using the positioning pin and positioning pin hole, and the flame-retardant rubber sealing ring is tightened. After connection, air tightness and air leakage are tested. Electrical interface 63 is inserted along the guide groove and locked, then fitted with a waterproof and dustproof sleeve. Continuity and insulation are tested using a multimeter and megohmmeter. Automatic control interface 64 is plugged into and connected to the switch; Modbus or Profinet communication is tested, and the communication response is recorded. When the enclosure is connected to the main building, the size of the connection opening should be 50-100mm larger than the outer diameter of the pipeline passing through the opening. A sleeve with a waterproof flange should be installed at the location where the pipeline passes through the floor slab or exterior wall. After the pipeline is connected, fireproof sealant should be used to seal the space between the sleeve and the pipeline. At the same time, the corresponding connection with the electrical and fire protection systems of the main building should be completed. The data for pressure testing, air leakage, insulation, communication and sealing acceptance should be associated with the corresponding BIM codes.

[0044] After all modules are connected, overall linkage debugging is performed. Equipment operating parameters and control logic are checked and adjusted according to on-site conditions. Subsequently, continuous trial operation is conducted for no less than 72 hours, collecting equipment pressure, temperature, energy consumption, and communication status every 2 hours, while simultaneously checking operational stability and noise levels. If abnormal pressure, communication interruption, or noise occurs, the abnormal point and rectification process are recorded at the corresponding component location in the BIM model. Re-verification is performed after rectification. A trial operation report is generated upon completion. The construction, design, supervision, construction, and operation and maintenance units conduct acceptance testing on installation accuracy, operating parameters, system functions, interface sealing performance, and fire linkage. Acceptance forms, image data, test reports, and rectification records are all linked to the corresponding entity's 16-bit BIM code and entered into the as-built dataset.

[0045] After acceptance, design, production, construction, commissioning, and acceptance data are integrated to form a BIM digital as-built model. The model includes equipment and pipeline technical parameters, installation records, test reports, warranty information, and unique codes. It is then transferred to the construction and operation and maintenance units according to the digital delivery standards adopted for the project. A link is then established between the BIM 3D model, equipment codes, and real-time collected data with the building intelligent operation and maintenance platform. The platform includes modules for equipment ledger, operational status monitoring, fault early warning, maintenance plans, energy consumption analysis, space management, and auxiliary upgrades. In this embodiment, the absolute value of the deviation of the air supply temperature of air conditioning unit 21 from the set value exceeding 2℃, the electrical current exceeding the rated value by 10%, and the automatic control communication delay exceeding 500ms are used as project early warning thresholds. When these thresholds are reached, the platform locates the corresponding equipment and retrieves the factory parameters, maintenance records, and warranty information under that code. The platform also generates monthly or quarterly maintenance work orders based on the equipment maintenance cycle recorded in the BIM. After maintenance is completed, the records are updated by scanning the code, and the equipment operation strategy is optimized based on operation and energy consumption data. After equipment repair or component replacement, information such as part model, repair time, and repair personnel will continue to be written into the original entity file. During subsequent expansion or renovation, the original interface coordinates and equipment parameters will be called back to perform collision checks and detailed design based on the existing as-built model. Standardized modules can also be added, replaced, or migrated as a whole according to the established interface relationships.

[0046] In this embodiment, over 90% of the cutting, welding, corrosion protection, insulation, and assembly processes are moved to the factory for completion, based on project workflow statistics. On-site work primarily focuses on transportation acceptance, hoisting and positioning, module assembly, building connection, and overall commissioning, thereby reducing on-site dust, noise, wastewater, and construction waste. Statistical results for the corresponding project in this embodiment show that compared to the original on-site assembly method, the on-site construction cycle is shortened by over 60%, on-site labor input is reduced by approximately 50%, construction waste is reduced by approximately 90%, material utilization is increased by approximately 15%, and operation and maintenance efficiency or manual inspection workload is improved by approximately 40%. The project also records a reduction of approximately 40% in later modification costs. These figures are specific project implementation records and are not intended as mandatory indicators for all construction projects. Project collaboration can adopt an EPC and BIM collaborative management approach, enabling design, equipment supply, factory prefabrication, on-site construction, and operation and maintenance data to be integrated within the same model and coding system.

[0047] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
