Description

Technical Field

[0001] The present application relates to the field of architectural design technology, and in particular to a method, equipment, and medium for arranging an exhaust system based on a pump room. Background Art

[0002] In the field of building HVAC design, the layout of the pump room exhaust system is a key link to ensure the safe operation of the equipment. The current design process mainly relies on manual experience combined with two-dimensional drawings: designers need to manually extract the spatial parameters in the building model, calculate the exhaust volume according to the specifications, and then complete the fan selection through sample comparison. Finally, draw the duct routing and component layout. This model has significant flaws: First, the manual calculation and selection process is cumbersome, and the exhaust volume calculation relies on the designer's subjective interpretation of the specifications, which can easily lead to deviations in the results due to differences in experience; second, there is a lack of standardized methods for duct path planning. Designers need to repeatedly adjust to avoid building obstacles, which is not only time-consuming but also difficult to ensure the rationality of the path; finally, the component layout relies entirely on manual arrangement, and the connection spacing is arbitrarily controlled, which can easily conflict with the building model or violate the design specifications.

[0003] While some existing 3D BIM-assisted tools exist, their functionality is limited to improving the efficiency of a single step and they fail to achieve full-process collaboration. For example, duct routing generation is disconnected from component selection, requiring manual secondary adjustments to component dimensions after path planning. Design results also lack real-time compliance verification, with conflicts only passively detected during the drawing phase, leading to frequent rework. More critically, existing tools are unable to achieve standardized output at the system level: The outputs of different projects and even different designers vary significantly in fan configuration, accessory connection methods, spacing control, and other aspects, reducing design reliability and increasing construction coordination costs. Summary of the Invention

[0005] On the one hand, an embodiment of the present application provides a method for arranging an exhaust system based on a pump room, comprising: Obtaining spatial parameters in a building information model, and calculating the minimum exhaust volume of the pump room using an air change method based on the spatial parameters, wherein the spatial parameters include room area, floor height, beam height, and obstacle location information; Identify the distribution of obstacles in the pump room, define the priority of the passage area, and generate the air duct routing path based on the path planning algorithm; Calculating the components of the duct based on the minimum exhaust volume, the duct routing path, and the preset wind speed limit, selecting fan parameters corresponding to the exhaust system, and determining the duct cross-sectional area; the fan parameters include model parameters and air volume; According to the cross-sectional area of ​​the air duct and the fan parameters, the corresponding air duct components are automatically matched, and the air duct components are spatially arranged and combined according to preset standardized connection rules.

[0006] In one implementation of the present application, the obstacle distribution in the pump room is identified, the priority of the passage area is defined, and the air duct routing path is generated based on the path planning algorithm, specifically including: The building area is divided into free-traffic areas, one-way-traffic areas, and restricted-traffic areas, and multiple candidate paths are generated based on the user-entered starting and ending locations and the area division results; the free-traffic areas include exhaust shafts and walkways, and the restricted-traffic areas include stairwells and elevator areas; Based on a preset path optimization strategy, a final route is determined from multiple candidate paths; the final route represents a path with the fewest turns or the fewest wall penetrations.

[0007] In one implementation of the present application, automatically matching corresponding duct components according to the duct cross-sectional area and the fan parameters specifically includes: Based on the calculation results of the duct cross-sectional area, candidate duct sizes that meet the preset aspect ratio threshold are screened from the preset duct size table; Among the candidate duct sizes, a target duct size having a duct cross-sectional area greater than the calculated result and an aspect ratio less than a preset aspect ratio threshold is preferentially selected; The target duct size is matched with the interface parameters of adjacent components and checked. If the check fails, a duct size that matches the interface parameters is selected from the candidate duct sizes.

[0008] In one implementation of the present application, after spatially arranging and combining the air duct components according to a preset standardized connection rule, the method further includes: Comparing the spatial layout combination of the exhaust system with the spatial position relationship of the structural columns and walls in the building information model to determine whether the spatial layout combination meets the building design specifications; Detect whether there is a conflict area in the air duct routing path that collides with an obstacle. If so, mark the conflict area and trigger a model correction instruction to push corresponding model correction suggestions to the user.

[0009] In one implementation of the present application, fan parameters corresponding to the exhaust system are selected, specifically including: According to the minimum exhaust volume, a fan model with a matching air volume range is selected from a preset fan sample library; Extract the 7 motor power parameters of the fan model and bind the 7 motor power parameters to the three-dimensional model of the pump room.

[0010] In one implementation of the present application, the air duct components are spatially arranged and combined according to preset standardized connection rules, specifically including: According to the air duct routing plan, determine the relative position and connection method between the components of the air duct; The air duct components are spatially arranged and combined according to predetermined standardized connection rules, the relative positions and the connection methods to ensure that a preset distance is maintained between the exhaust system and the structural components of the pump room.

[0011] In one implementation of the present application, based on the space parameters, the minimum exhaust volume of the pump room is calculated by the air change rate method, specifically including: Determine the type of the water pump room and the standard air change rate corresponding to the water pump room type, and calculate the minimum exhaust volume of the water pump room by the air change rate method; Calibrate the minimum exhaust volume to determine whether the minimum exhaust volume meets preset building design specifications; the building design specifications include requirements for exhaust fan area and wind speed; If the calibration fails, a modification prompt corresponding to the model data of the building information model is generated until the calculated minimum exhaust volume matches the preset design specification.

[0015] The embodiments of the present application provide a method, device, and medium for arranging an exhaust system based on a pump room, which have at least the following beneficial effects: By automatically parsing the spatial parameters of the building information model, the minimum exhaust volume is calculated directly based on the standard air change frequency method, avoiding the subjective errors of manual calculations. The path planning algorithm is combined to dynamically generate duct routes, intelligently avoid obstacles such as structural columns and walls, and optimize the path based on the priority of the traffic area, significantly reducing the time required for traditional manual trial-and-error layout. Fan parameters are selected based on the minimum exhaust volume, duct route path, and preset wind speed limit, and the duct cross-sectional area is calculated based on the fan parameters. Component sizes that meet the aspect ratio threshold and interface compatibility are automatically selected to resolve the rework problem caused by the disconnect between manual selection and path selection. Pre-set standardized connection rules are used for spatial layout combination to ensure that the exhaust system strictly matches the building model and eliminate construction conflicts caused by differences in design habits. The collision risk between the duct path and obstacles is checked in real time during the layout combination stage, and model correction instructions are triggered to achieve a concomitant closed loop of design, verification, and correction, eliminating the output of solutions that violate building design specifications from the source.

DETAILED DESCRIPTION

[0017] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0019] Figure 1 A flow chart of a method for arranging an exhaust system based on a pump room provided in an embodiment of the present application.

[0020] The analysis method involved in the embodiments of the present application can be implemented by a terminal device or a server, and the present application does not impose any special restrictions on this. For ease of understanding and description, the following embodiments are described in detail using a server as an example.

[0021] It should be noted that the server can be a single device or a system composed of multiple devices, that is, a distributed server, and this application does not make any specific restrictions on this.

[0022] like Figure 1 As shown, an embodiment of the present application provides a method for arranging an exhaust system based on a pump room, comprising: Step 101: Acquire space parameters in a building information model, and calculate the minimum exhaust volume of the pump room based on the space parameters using an air change rate method.

[0023] It should be noted that the spatial parameters in the embodiment of the present application include room area, floor height, beam height and obstacle location information.

[0024] The pump room exhaust system is a mechanical ventilation method designed for special scenarios, such as domestic water pump room or fire water pump room, which should be met by architectural design requirements. It mainly uses exhaust fans to extract the air in the domestic water pump room or fire water pump room, and then uses supply fans to transport air to the domestic water pump room or fire water pump room to ensure the normal organization of the air flow in such rooms, and prevent the air in the enclosed space from being unable to be replaced for a long time, resulting in excessively high CO concentration and people being unable to enter the room to repair the machine.

[0025] Figure 2 This is a schematic diagram of the internal structure of an exhaust system arrangement device based on a pump room provided in an embodiment of the present application. Figure 2 As shown, this application mainly includes a model acquisition module, a data calculation and verification module, a duct routing planning module, a duct component data calculation module, and a pump room exhaust system assembly module. The model acquisition module is used to read the civil engineering and structural models in the Building Information Modeling (BIM), which mainly include spaces such as rooms, components such as structural columns and walls, and spatial data such as area, floor height, and beam height. The data calculation and verification module processes the data obtained by the model acquisition module, such as room area, floor height, and beam height, and combines it with the air change rate method to calculate the minimum exhaust volume of the room, providing assistance for the subsequent selection of fans for the exhaust system.

[0026] In this example, the system first uses the Model Acquisition panel to read the civil and structural models in the BIM and automatically obtain the spatial parameters of the pump room. For example, these spatial parameters include key information such as room area, floor height, beam height, and obstacle location. These spatial parameters together form the basic data for calculating the minimum exhaust volume.

[0027] By parsing the spatial information in the Building Information Model (BIM), the system identifies the pump room area and its adjacent spatial boundaries, and extracts the coordinates and dimensions of structural components such as columns and walls. The system then calls the BIM software's API to automatically locate the pump room's enclosed contour and calculate its projected area. It also dynamically determines the effective floor height by reading the difference between the floor slab elevation and the beam bottom elevation. It's important to note that obstacle location information directly impacts subsequent duct routing. For example, the location of structural columns serves as a key constraint for path avoidance.

[0028] The air change rate method calculates exhaust air volume based on the pump room type (e.g., domestic water pump room or fire pump room) and the specified air change rate. Specifically, the system uses a specific formula based on acquired space parameters and the specified air change rate to determine the minimum exhaust air volume for the pump room.

[0029] It should be noted that by automatically obtaining space parameters and calculating the minimum exhaust volume, the system can ensure that the design of the exhaust system not only meets the regulatory requirements but also effectively meets the ventilation needs of the pump room.

[0030] After calculating the minimum exhaust volume for the pump room, verify that the calculated results meet the building design code requirements for exhaust shaft cross-sectional area and wind speed. If the calibration fails, a model modification prompt is generated. For example, if the exhaust shaft is undersized, the user is prompted to expand the shaft cross-section or adjust its position.

[0031] In this embodiment, for the water pump room scenario, the calculation is performed based on the area parameters of the domestic water pump room or the fire water pump room and the height information of the room. The main calculation method used is the air change rate method, and the calculation formula is as follows:

[0032] Where L (exhaust volume) represents the calculated minimum exhaust volume for the pump room, S (room) represents the area of ​​the pump room obtained from the model reading module, H (height) represents the height within the pump room obtained from the model reading module, and N (air changes) is determined based on the standard value. For example, the air changes for the domestic water pump room are 4 times / hour, and the air changes for the fire water pump room are 6 times / hour.

[0033] This application also includes a model review phase, which mainly reviews whether the basic model results provided for the building meet the minimum design parameters. The main object of the review is the area of ​​the exhaust shaft, which is calculated using the formula:

[0034] Among them, L exhaust volume represents the minimum exhaust volume of the pump room calculated by the air change frequency method, and V exhaust shaft represents the preset wind speed limit specified in the specification, which is an interval range value, such as 6-10m / s. It should be noted that the embodiment of the present application is mainly aimed at the exhaust shaft in the basement, and the exhaust shaft wind speed required in different scenarios has different limit intervals. For example, the basement uses a lower wind speed to reduce noise. The embodiment of the present application uses the maximum wind speed as a reference value for calculation, and the verified parameters are the minimum design standards. The calculated S exhaust fan is compared with the exhaust shaft value obtained in the model reading module. If the calculated result is greater than the read result, it indicates that the basic model data does not meet the design requirements, and the design is terminated. The model needs to be returned to the building side for modification. If the calculated result is less than the read result, it indicates that the basic data meets the design requirements, and the design continues.

[0035] Step 102: Identify the distribution of obstacles in the pump room, define the priority of the passage area, and generate the air duct routing path based on the path planning algorithm.

[0036] In this embodiment, the duct routing plan section is used to determine the length and position of the exhaust system on a planar surface. The system further identifies the distribution of obstacles within the pump room, which may include structural columns, walls, and other structures. For example, the system automatically identifies and marks the locations of these obstacles by reading component information from the BIM model.

[0037] Understandably, to plan a reasonable duct routing, the system needs to prioritize traffic areas. Specifically, based on the actual usage requirements and design specifications of the pump room, the system defines areas like exhaust shafts and walkways as high-priority traffic areas, while areas like stairwells and vestibules are defined as low-priority or non-traffic areas.

[0038] Next, the system automatically generates a duct routing path based on a path planning algorithm, such as the A* algorithm, and preset traffic zone priorities. For example, the algorithm considers factors such as the location of obstacles, traffic zone priorities, and the length and smoothness of the path to find the optimal duct routing path.

[0039] In this embodiment, the duct routing planning module mainly includes two different forms of expression. The first form is that the user manually draws the duct routing line according to the prompts of the interactive interface as the basis for subsequent system generation. The second form is that the user specifies the starting point and end point of the route, and the program automatically generates multiple results of the duct routing based on the specified starting and end points.

[0040] Specifically, the user manually draws the start and end points, using a two-point pathfinding method (A* algorithm). The specific algorithm is not described in detail in this application. The pathfinding width is determined. The pathfinding width is the expected width of the air duct. Its main purpose is to generate the automatically generated path with a virtual width, so as to determine whether the final pipeline will collide with obstacles such as walls and columns.

[0041] After defining the traversable categories for each room or area, possible rooms are screened in the configuration table, mainly divided into three categories: free passage, one-way passage, and impassable. It should be noted that the rooms defined as free passage are exhaust shafts, corridors, parking areas, and other rooms. Corridors and parking areas have a higher priority, while other rooms have a lower priority. Rooms with keywords containing "electricity" and "pump" in their names should be avoided as much as possible and have a lower priority. One-way passage is defined as the pump room, which only allows entry but not exit, and the exhaust shaft room, which only allows exit but not entry. Impassable rooms are defined as stairwells, vestibules, supply (supplement) fan rooms, elevators, elevator halls, and entrance lobbies.

[0042] Define potential obstacles during the traversal process, such as columns, structural walls, building walls, and parking spaces. For columns, the path cannot enter this obstacle. For structural walls, the path cannot enter this obstacle. For building walls, the path can traverse this obstacle. For parking spaces, the path can traverse this obstacle. Next, define the pathfinding strategy. There are two main pathfinding strategies for the pump room's exhaust system: fewer turns and fewer wall penetrations. These two strategies are provided primarily for user selection on the interface. Once the above automatic pathfinding requirements are met, a pathfinding strategy can be generated between two points using the program algorithm.

[0043] Step 103: Calculate the components of the duct according to the minimum exhaust volume, the duct routing path, and the preset wind speed limit, select the fan parameters corresponding to the exhaust system, and determine the duct cross-sectional area.

[0044] It should be noted that the fan parameters in the embodiment of the present application include model parameters and air volume.

[0045] In this embodiment, models with matching air volume are screened from a preset sample library based on the minimum exhaust volume, and motor power parameters are extracted and bound to the three-dimensional model of the pump room.

[0046] In this embodiment, the system performs detailed calculations on the components of the duct based on the previously calculated minimum exhaust volume, the planned duct routing path, and the preset wind speed limit. For example, the system calculates the cross-sectional area of ​​the duct based on the minimum exhaust volume and wind speed limit. The calculation formula is as follows:

[0047] in, Represents the cross-sectional area of ​​the duct. It should be noted that the calculated cross-sectional area of ​​the duct will be used for subsequent sizing. For example, if the fan outlet has a circular flange, the square-to-circular reducer selection logic is automatically triggered.

[0048] It's understandable that determining the duct cross-sectional area is fundamental to selecting fan parameters. Specifically, the system automatically selects a fan model that meets design requirements based on the calculated duct cross-sectional area, combined with the fan's performance curve and sample library. Furthermore, the system further determines the size and type of the air outlet based on parameters such as the fan's air volume and pressure. It's important to note that by automatically selecting fan parameters and calculating the duct cross-sectional area, the system ensures that the exhaust system's performance meets both design requirements and achieves efficient operation.

[0049] In this embodiment, when selecting the fan parameters corresponding to the exhaust system, based on the minimum exhaust volume, the fan model that matches the air volume range is screened from the preset fan sample library, and then the motor power parameters of the fan model that matches the screened air volume range are extracted, and then the motor power parameters are bound to the three-dimensional model of the pump room.

[0050] In this embodiment, the duct component data calculation module calculates the duct components one by one based on the previously calculated results and automatically selects the components. The duct components mainly consist of fans, ducts, air outlets, duct accessories, and silent devices.

[0051] First, the fan is selected based on the calculated minimum exhaust volume value. The selection principle is based on the following formula:

[0052] After calculating the fan's selected air volume, enter the background preset samples to select the fan model, and record the data in the fan itself in the form of parameters. The recording method is to automatically add instance parameters to the fan family for data recording. Service partitions are recorded by room name, such as the basement domestic water pump room and the above-ground fire water pump room; the motor power is obtained from the sample; the installation method provides options, ground-mounted and hoisted, which are determined based on the actual generated results.

[0053] This application primarily provides fixed duct accessory generation to meet user needs. These are provided through custom families, primarily for the self-built M_Duct Check Valve, the self-built M_70°C Fire Damper, and the self-built M_Electric Damper. This application primarily provides mufflers as system silencing devices, also provided through custom families, primarily for the self-built M_Muffler.

[0054] Based on the fan air volume value selected previously and the fixed duct wind speed limit in the standard, the cross-sectional area of ​​the duct is determined. The duct size is automatically generated based on the cross-sectional area and the duct size selection table is provided.

[0055]

[0056] The wind speed value of the air duct in this application is determined by the user when using the function. The function also provides a preset default value, which can also be used as a data source input. The air duct cross-sectional area is calculated based on the air volume value accommodated by the selected fan model and the above formula. After the calculation is completed, the air duct size is selected. Common air duct size values ​​are provided in this application. The selection method is to determine the cross-sectional area calculated by the air outlet size and compare it with the result of the above calculation. The calculated air duct cross-sectional area value is required to be less than the cross-sectional area of ​​the size in the table. The table is as follows:

[0057] There are multiple result values ​​obtained in the above manner, and further selection and judgment are made based on the aspect ratio of the size. Duct sizes with similar aspect ratios are preferred, and the height value of the style duct diameter is ≤400mm. The aspect ratio should not be greater than 4 and should not be greater than 6.

[0058] The principle of selecting the exhaust vent is similar to that of the air duct. Calculate the cross-sectional area of ​​the vent according to the formula

[0059] After obtaining the cross-sectional area of ​​the air outlet, screen the air outlet cross-sectional area according to the commonly used air outlet size values. The screening principles are as follows: 1. The air outlet cross-sectional area value is less than the cross-sectional area of ​​the size in the table; 2. The length-to-width ratio of the air outlet should not be greater than 4 and should not be greater than 6; 3. Unlike the cross-sectional area of ​​the air duct, when the cross-sectional area of ​​the air duct is determined, the width value of the selected air outlet should be less than the width of the air duct.

[0060] Step 104: Automatically match corresponding duct components according to the duct cross-sectional area and fan parameters, and spatially arrange and combine the duct components according to preset standardized connection rules.

[0061] In this embodiment, candidate specifications with an aspect ratio ≤ 4 are screened from the size table based on the cross-sectional area of ​​the duct. Dimensions with a cross-sectional area greater than the calculated value and compatible interfaces are preferentially selected, such as matching the fan outlet flange with the duct flange. If the verification fails, a suboptimal dimension is iteratively selected.

[0062] Determine the relative position of components according to the routing path, such as the preset distance between the fire damper and the wall. When there is insufficient space, insert the elbow and compress the distance to the minimum allowable value, and maintain the second preset distance between the silencer and the adjacent accessories.

[0063] Scan for spatial conflicts between ducts and structural beams and columns, mark collision areas, and provide correction suggestions, such as adjusting elevations or adding detour elbows. The system also outputs a 3D BIM model and parts list with avoidance annotations.

[0064] It's important to note that standardized connection rules incorporate economic and construction feasibility constraints, such as a standard 90° elbow angle to simplify fabrication. For example, if the distance between a fire damper and the wall is insufficient, the system automatically shortens the straight pipe section and inserts a flexible joint to compensate for installation errors.

[0065] In this embodiment, the system automatically matches the corresponding duct components from a pre-set component library based on the previously calculated duct cross-sectional area and selected fan parameters. For example, these components include ducts, fans, air outlets, and duct accessories such as check valves, fire dampers, electric dampers, and mufflers.

[0066] Understandably, to ensure the effectiveness and safety of the duct system, the system requires the spatial layout and combination of these components according to pre-set standardized connection rules. Specifically, the system automatically determines the connection method and relative position of each component based on the duct routing and component size, shape, and other information. The system also considers the spacing requirements between components to ensure ease of installation and maintenance.

[0067] For example, the system first determines the fan's location and then arranges the ducts, air outlets, and other accessories based on the duct's orientation and dimensions. During the layout process, the system checks in real time whether the spacing and connection methods between components meet standardized requirements, making timely adjustments and optimizations. Ultimately, the system generates a complete and effective pump room exhaust system design, including a 3D model, 2D drawings, or data reports.

[0068] In this embodiment, in the pump room exhaust system assembly module, the fire damper is placed outside the exhaust shaft wall with a distance of 100 mm between the valve edge and the wall edge. If there is space behind the fire damper for a check valve, the distance between the fire damper and the check valve edge is 100 mm. If there is insufficient space for a check valve, a corresponding elbow is generated based on the path, with no specific distance requirement. If there is sufficient space behind the elbow for a muffler, the distance between the check valve and the elbow edge is 50 mm. The fire damper width is fixed at 260 mm.

[0069] If there's enough space behind the check valve to place a muffler, the distance from the muffler edge is 100mm. If there's no space, an elbow is placed based on the path, and the distance is not controlled. If there's enough space behind the elbow to place a muffler, the distance from the muffler edge to the elbow edge is 50mm. The check valve width is fixed at 300mm.

[0070] The silencer is followed by an electric damper. If there's enough space behind the muffler to place the damper, the distance between the damper and the edge of the damper is 100mm. If there's not enough space, an elbow is placed based on the path, and the distance is not controlled. If there's enough space behind the elbow to place the damper, the distance between the damper and the elbow is 50mm. The muffler width is fixed at 1000mm.

[0071] The electric damper is followed by a reducer, flexible connector, fan, and reducer. If there's enough space behind the electric damper to place the reducer, flexible connector, fan, and reducer, the distance between them is 50mm. If there's not enough space, an elbow is placed based on the path, and the distance between them is not controlled. If there's enough space behind the elbow to place the electric damper, the distance between the reducer, flexible connector, fan, and reducer is 50mm. The width of the reducer, flexible connector, fan, and reducer is not fixed and is determined primarily by the size of the reducer and the fan.

[0072] Reducer + flexible connector + fan + reducer, followed by a muffler. If there is enough space to place the muffler after the reducer + flexible connector + fan + reducer, the distance from the muffler is 50mm. If there is not enough space to place the muffler, an elbow is placed according to the path search, and the distance is not controlled. If there is enough distance after the elbow to place the muffler, the distance between the muffler and the elbow is 50mm. The muffler width is fixed at 1000mm.

[0073] Air ducts are generated for all subsequent paths, and exhaust vents are placed 100 mm away from the end of the path.

[0074] The above is an embodiment of the method proposed in this application. Based on the same inventive concept, the embodiment of this application also provides an exhaust system arrangement device based on a water pump room, the structure of which is as follows: Figure 3 shown.
