Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building equipment, in particular to a method for automatically arranging air outlets of an air conditioning system in a public area of a subway building. BACKGROUND

[0002] In the existing air conditioning system of a public area of a subway building, the arrangement of air outlets often depends on manual design. This design method is time-consuming and easily affected by human factors, resulting in unreasonable arrangement of air outlets.

[0003] In order to improve the efficiency and intelligent level of the air conditioning system, an algorithm is needed to automatically arrange air outlets according to the geometric shape of the room, the density of personnel and the position of obstacles, so as to realize efficient arrangement of air outlets and improve the uniformity and flexibility of air supply and return air. SUMMARY

[0004] The purpose of the present application is to provide a method for automatically arranging air outlets of an air conditioning system in a public area of a subway building, which optimizes the arrangement position of air outlets by analyzing the circumscribed rectangle of the room, generating scan lines, dividing air supply and return air areas, and arranging air outlets according to the scan lines, to ensure efficient implementation of air supply and return air functions, while avoiding obstacles in the building.

[0005] The technical solution adopted by the present application is:

[0006] A method for automatically arranging air outlets of an air conditioning system in a public area of a subway building can realize automatic arrangement of air outlets in a public area of a subway building, which specifically includes the following steps:

[0007] S1, obtaining geometric information of the room and generating a circumscribed rectangular area;

[0008] S2, selecting the long side of the circumscribed rectangle as the scanning direction, and dynamically adjusting the interval of the scan lines according to the distribution of obstacles in the room, to generate scan lines with a preset interval;

[0009] S3, deleting scan lines with a distance less than a preset distance threshold from the wall and column;

[0010] S4, determining the number of scanning areas according to the short side of the circumscribed rectangle and a preset area division interval, and setting at least two scanning areas;

[0011] S5, dividing the scan lines according to the number of scanning areas;

[0012] S6, selecting the middle position of each scan line as an air outlet arrangement line segment;

[0013] S7, determining the number of air outlets on each arrangement line segment according to the set air outlet interval, and then arranging the air outlets to ensure that the air outlets maintain a safe distance from the obstacles and are dynamically adjusted according to the area function.

[0014] S8, calculating the air volume of each air port and selecting the air port according to the air port sample database, and completing the air port arrangement.

[0015] Further, the specific method of step S1 is: generating an outer rectangular region by inputting the geometric shape data of the room, to serve as the basis for subsequent scanning and air port arrangement, wherein the long side of the outer rectangle is used to determine the generation direction of the scanning line, and the short side is used to divide the functional area.

[0016] Further, the specific method of step S2 is: generating a series of parallel scanning lines in the rectangle according to a certain interval based on the long side direction of the outer rectangle, covering the entire range of the room, to provide a reference line for subsequent air port arrangement.

[0017] The dynamic adjustment of the interval of the scanning line is based on the density of the obstacles in the room. Specifically, in the area where the obstacles in the room are dense (such as places with more obstacles such as columns and walls), the interval of the scanning line will be automatically reduced to ensure that the air port arrangement can avoid obstacles and achieve more accurate layout; while in the area where the obstacles in the room are sparse, the interval of the scanning line can be appropriately increased to improve the efficiency of the air port arrangement.

[0018] Further, the specific method of step S3 is: by detecting the interval distance between the scanning line and the walls and columns in the room, deleting the scanning line whose interval distance is less than a preset distance threshold, to avoid the air port arrangement at an inappropriate position; wherein the preset distance threshold is dynamically set according to the distribution characteristics of the internal obstacles of the room, and the default is 1 meter, i.e. deleting the scanning line whose distance to the wall or column is less than 1 meter.

[0019] Further, the specific method of step S4 is: determining the number of divided scanning areas by analyzing the short side of the outer rectangle and combining the preset area division interval; at least 2 scanning areas are set to ensure that the air port arrangement is in a reasonable functional area; wherein the default preset interval is 4m.

[0020] Further, the specific method of step S5 is: when the number of scanning areas can be divided by 4, then divide along the scanning direction in the order of "supply air, return air, return air, supply air" alternately; otherwise, the odd scanning lines are classified as supply air, and the even scanning lines are classified as return air. This division method ensures the uniform distribution of supply air and return air.

[0021] Further, the specific method of step S6 is: selecting the scanning line at the middle position in each scanning line class as the air port arrangement line segment, to ensure that the arranged air ports are uniformly distributed in each functional area.

[0022] Further, in step S7, the safety distance and special area function are adjusted according to the type of the obstacle when the air port is arranged, wherein:

[0023] The distance between the air vent and common obstacles (such as pillars) should be no less than 1 meter;

[0024] The distance between the air vent and special obstacles (such as smoke curtains) shall not be less than 5 meters;

[0025] The safe distance for other obstacles is dynamically set according to different obstacle types;

[0026] In the reception center's strategic location, ensure proper airflow by arranging air vents to guarantee air circulation and comfort;

[0027] In sensitive areas of the security checkpoint, air conditioner units should be installed away from air vents to prevent water from dripping onto the equipment below.

[0028] Furthermore, the specific method of step S8 is as follows: calculate the air volume required by each air outlet based on the air volume information required by the room, and select a suitable air outlet size based on the air outlet sample database to ensure that the performance of the air conditioning system reaches the expected effect.

[0029] The present invention, employing the above technical solution, offers the following advantages compared to existing technologies: By combining the room's geometric structure and air circulation requirements, the present invention automatically arranges air vents and avoids obstacles, thereby effectively improving the air supply and return efficiency of the air conditioning system. Compared to traditional manual design methods, this algorithm significantly reduces design time. Traditional manual design of air vent locations typically takes three to five minutes and often involves multiple modifications and adjustments; while the automated algorithm of this invention can complete the design within ten seconds, significantly improving work efficiency, reducing manual workload, and ensuring the rationality and flexibility of air vent placement, making it particularly suitable for complex public areas in subway buildings.

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0039] As shown in Fig. 1, the present application discloses an air outlet automatic arrangement method of a subway building public area air conditioning system, which comprises the following steps: Figures 1 to 7

[0040] S1, obtaining the geometric information of the room and generating a circumscribed rectangular region.

[0041] More specifically, by inputting the geometric shape data of the room, a circumscribed rectangular region is generated as the basis for subsequent scanning and air outlet arrangement, wherein the long side of the circumscribed rectangle is used to determine the generation direction of the scanning line, and the short side is used to divide the functional area. Room information and circumscribed rectangle schematic diagram can be seen in Fig. 2.

[0042] S2, selecting the long side of the circumscribed rectangle as the scanning direction, and dynamically adjusting the interval of the scanning line to generate the scanning line.

[0043] More specifically, based on the long side direction of the circumscribed rectangle, a series of parallel scanning lines are generated in the rectangle according to the preset interval, covering the entire range of the room, providing reference lines for subsequent air outlet arrangement. Wherein, the interval of the scanning line is dynamically adjusted based on the density of the obstacles in the room, in the area where the obstacles such as columns in the room are dense, the interval of the scanning line will automatically decrease; while in the area where the obstacles in the room are sparse, the interval of the scanning line can be appropriately increased. The scanning line in the room is shown in Fig. 3. Figure 3 .

[0044] S3, deleting the scanning line with a distance less than a preset distance threshold from the wall and column.

[0045] More specifically, by detecting the distance between the scanning line and the wall and column in the room, those scanning lines with too close distance are deleted to avoid the air outlet being arranged at these inappropriate positions. Wherein, the preset distance threshold is dynamically set according to the distribution characteristics of the internal obstacles of the room, and the default is 1 meter, that is, the scanning line with a distance less than 1 meter from the wall or column is deleted. The schematic diagram of the removed part of the scanning line is shown in Fig. 4. Figure 4 .

[0046] S4, determining the number of scanning regions according to the short side of the circumscribed rectangle and the preset region division interval. ​

[0047] More specifically, by analyzing the short side of the circumscribed rectangle and combining the preset regional division distance, the number of scanning regions that can be divided is determined. The minimum is set to 2 scanning regions, ensuring that the air outlet is arranged in a reasonable functional area. The default preset distance is 4m, i.e. the number of regions is max(2, S / 4).

[0048] S5, divide the scanning lines into several scanning line classes according to the scanning direction.

[0049] More specifically, the scanning lines are divided according to the number of scanning regions. If the number of scanning regions is divisible by 4, they are alternately divided along the scanning direction in the order of "supply air, return air, return air, supply air"; otherwise, the odd scanning line class is supply air and the even scanning line class is return air. This division ensures uniform distribution of supply air and return air. The schematic diagram of the above different division methods can be seen in Figure 5 and Figure 6 .

[0050] S6, select the middle line in each scanning line class as the air outlet arrangement line segment.

[0051] More specifically, the middle scanning line in each scanning line class is selected as the air outlet arrangement line segment, ensuring that the arranged air outlets are uniformly distributed in each functional area. The schematic diagram can be seen in Figure 5 and Figure 6 .

[0052] S7, avoid obstacles for air outlet arrangement on the arrangement line segment.

[0053] More specifically, on each arrangement line segment, the number N of air outlets is determined according to the preset air outlet distance, and the arrangement is made. The default air outlet distance is 3m, i.e. the number N of air outlets is the length of the arrangement line segment / 4. When arranging air outlets, the safety distance needs to be adjusted according to the type of obstacle and dynamically adjusted according to the function of the region, wherein:

[0054] The distance between the air outlet and the general obstacle (such as a column) is not less than 1 meter;

[0055] The distance between the air outlet and the special obstacle (such as a smoke screen) is not less than 5 meters;

[0056] The safety distance of other obstacles is dynamically set according to different obstacle types.

[0057] In special places such as reception centers, it is necessary to ensure that the air outlets are arranged to ensure air circulation and comfort;

[0058] In sensitive areas such as security checks, air outlets should be avoided to prevent air conditioner water from dripping onto the equipment below.

[0059] The method in the embodiment is to generate a plurality of point positions on the arrangement line segment, divide the selectable point positions and the eliminated point positions according to the distance from the obstacles, and then find out N evenly divided selectable point positions from the selectable point positions as the regular arrangement point positions, and the reception center needs special arrangement of the air outlets. The specific air outlet obstacle avoidance arrangement schematic diagram can be seen from Figure 7 .

[0060] S8, the air volume responsible for by each air outlet is calculated, and the air outlet selection is performed according to the air outlet sample database.

[0061] More specifically, after the number and position of the air outlets are determined, the required air volume responsible for by each air outlet is calculated according to the required air volume information of the room, and the appropriate air outlet size is selected based on the air outlet sample database to ensure that the performance of the air conditioning system reaches the expected effect. That is, the required air volume of each air outlet can be obtained according to the required air supply volume of the room and the number of room air supply outlets obtained in S7, the required air volume of each return air outlet can be obtained according to the required return air volume of the room and the number of room return air outlets obtained in S7, and the size selection is performed from the database according to the required air volume of a single air outlet.

[0062] Compared with the prior art, the application has the beneficial effects that: by combining the geometric structure of the room and the air flow demand, the air outlet arrangement is automatically performed and the obstacles are avoided, thereby effectively improving the air supply and return efficiency of the air conditioning system. Compared with the traditional manual design method, the design time is greatly reduced. The traditional manual design of air outlet position usually takes three to five minutes and is often accompanied by multiple modifications and adjustments. The automatic algorithm of the application can complete the design in ten seconds, significantly improving the work efficiency, reducing the manual workload, and ensuring the rationality and flexibility of the air outlet arrangement, especially suitable for complex subway building public areas.

The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
