  Conventionally, a facility designer calculates the necessary ventilation volume in a building based on laws and regulations such as the Building Standard Law or the number of ventilation times in a room, the amount of heat generated, etc., and designs equipment components based on the calculation result. doing. In addition, basically, ventilation in the building is air-balanced so that the sum of the air supply (OA) and the exhaust (EA) of each floor becomes zero based on the calculation result of the required ventilation. Designed.

Specifically, the worker uses the spreadsheet software such as Excel to calculate the required ventilation rate of the building to create the ventilation calculation table, and the CAD software is used to calculate the necessary ventilation of each room. An air balance diagram for air balance design is created by inputting the amount of air supplied and the amount of exhaust air of each room obtained based on the quantities in the building drawing (CAD drawing) of the building. However, in this method, the operator must manually create the ventilation calculation table, and manually enter the air supply amount and the exhaust amount numerically into the CAD drawing to create the air balance diagram. , The work is complicated. In particular, in the case of a large building such as an office building or various facilities, since there are a large number of rooms, it is burdensome to manually input the air supply amount and the exhaust amount of each room to a CAD drawing.
In addition, as described above, since the facilities of the building are designed using the ventilation calculation table, while the building itself is designed using the CAD drawing, the ventilation calculation table The ventilation rate may not be consistent with the ventilation rate of the air balance chart. Therefore, in order to match these ventilation rates, after confirming whether the ventilation rate entered in the ventilation calculation table matches the ventilation rate entered in the CAD drawing, if they do not match, correction work is performed There must be.

  Furthermore, in air balance design, work is usually performed because the positive pressure / negative pressure of the room is determined from the air supply amount and exhaust amount of each room, and the sum of positive pressure and negative pressure of each floor is adjusted to zero. When creating the air balance diagram, the person needs to manually correct the values of the air supply amount and the exhaust amount input to the CAD drawing as needed.

  Especially in recent years, it is often required to create a ventilation chart and an air balance chart at the design stage of a building as a measure against a sick house, and to meet such demands, the ventilation chart and the air balance chart must be accurate and quick. There is a need for a way to create

  Here, there is used a method of calculating a thermal load such as an air conditioning thermal load, a shell performance, or a primary energy consumption of a building such as a building using building attribute information for realizing BIM. At this time, the computer takes out information necessary for the calculation, such as the material, thickness, stacking order and area of the part of the material constituting each part of the building, from the three-dimensional model created based on the BIM information. The air conditioning heat load and the like are calculated based on the extracted information. As a thermal load calculation method using BIM information, for example, for at least a plurality of parts such as a wall, at least materials and stacking order of one or more materials constituting the parts are specified from three-dimensional CAD data, for example The site configuration information is acquired, and based on the acquired site configuration information, the site configuration information common to at least a plurality of sites common in material and stacking order is generated, and the common site configuration information for common calculation is It is disclosed that heat load calculation is performed using it (patent document 1).

  In addition, as a method of adjusting the air balance of the building, using the existing air conditioner, the rotational speed of the return air fan or the exhaust damper so that the differential pressure between the vertical space and the room or the movement amount of air becomes zero. A technique is disclosed that can control the loss of air conditioning energy and the deterioration of the indoor environment due to the air flow and the like by adjusting the opening degree (Patent Document 2).

Further, in the display area 43A, the value obtained by subtracting the exhaust amount (EA) from the air supply amount (OA) is “−350 m ³ / h”, which is smaller than 0, so WC (W) 43 is under negative pressure. I know that there is.

In the display area 44A, the room No. The room name “hallway” of 4, the air supply amount (OA) “0 m ³ / h” and the exhaust amount (EA) “0 m ³ / h” are input, and information indicating the ventilator is not input. Further, it is understood that the value obtained by subtracting the exhaust gas amount (EA) from the air supply amount (OA) in the display area 44A is “0 m ³ / h”, and the corridor 44 is in a pressure state equal to the external pressure.

In the display area 45A, the room No. A room name "machine room" of 5, an air supply amount (OA) "0 m ³ / h" and an exhaust amount (EA) "900 m ³ / h" are input. Information indicating ventilation equipment installed in the room, for example, "FE-103" indicating the machine number of the exhaust fan may be input to the display area 45A based on the ventilation calculation table 30 of FIG. "-" Is input to the air supply side, which indicates that natural ventilation is performed. Further, since the value obtained by subtracting the exhaust gas amount (EA) from the air supply amount (OA) in the display area 45A is “−900 m ³ / h”, it can be seen that the machine room is in a negative pressure state.

  Thus, in the air balance diagram 40, the chamber No. 1 to No. By displaying the display areas 41A to 45A for indicating the ventilation information of No. 5, the user can easily visually recognize the air supply amount (OA) and the exhaust amount (EA) of each room. In addition, since it is possible to recognize whether each chamber is in the positive pressure state or the negative pressure state, it is possible to easily adjust the sum of the positive pressure and the negative pressure of each floor to zero in the air balance design. it can.

  Further, in the air balance diagram 40, a frame 50 which defines each ventilation system is automatically displayed. With this frame 50, for example, the office room 41, WC (M) 42, WC (W) 43, and the corridor 44, which are the first ventilation system to be subjected to air balance, are zoned (range designation). Moreover, "301" which shows that it is a 1st ventilation system is displayed on the one part display area 50a in the zoning range. Room No. The machine room 45 is out of the range of the frame 50 because it is designed in advance so that the sum of the air supply amount (OA) and the exhaust amount (EA) becomes zero in the room alone. Thus, the user can confirm and adjust the air balance on each floor of the building by displaying each ventilation system, in particular, the frame 50 that defines the first ventilation system to be air balanced, in the air balance diagram 40 in this manner. It is easy to see the area that should be.

  Furthermore, in the air balance diagram 40, the chamber No. 1-Room No. Arrows indicating the ventilation paths respectively corresponding to 5 are automatically displayed, preferably in a form that distinguishes intake, exhaust or path.

  Specifically, room no. An arrow 41B-1 displayed in the 1 office room 41 indicates an air supply path of the office room 41, and is displayed as a solid line representing the air supply, for example. An arrow 41B-2 indicates an exhaust path of the office 41, and is displayed, for example, by an alternate long and short dash line representing exhaust. An arrow 44B-1 indicates an exhaust path from the office 41 to the corridor 44, and is displayed, for example, by a broken line representing a path. Thus, in the office room 41, arrows 41B-1, 41B-2, and 44B-1 indicating three ventilation routes are displayed in different line types.

  Room No. An arrow 42B displayed on the second WC (M) 42 indicates an exhaust path of the WC (M) 42, and is displayed, for example, by a dashed dotted line. An arrow 44B-2 indicates a path from the corridor 44 to the WC (M) 42, and is displayed by, for example, a broken line. That is, in WC (M) 42, arrows 42B and 44B-2 indicating two ventilation routes are displayed in different line types.

  Room No. Similarly to the case of WC (M) 42, an arrow 43B displayed on WC (M) 43 of No. 3 indicates an exhaust path of WC (M) 43, and is displayed by, for example, an alternate long and short dash line. An arrow 44B-3 indicates a path from the corridor 44 to the WC (W) 43, and is displayed by, for example, a broken line. That is, in WC (W) 43, arrows 43B and 44B-3 indicating two ventilation paths are displayed in different line types.

  Room No. Arrows 44B-1, 44B-2, and 44B-3 displayed in the four corridors 44 indicate paths as described above, and are displayed, for example, by broken lines. That is, in the corridor 44, arrows 44B-1, 44B-2, and 44B-3 indicating three ventilation paths are displayed with the same line type.

At this time, areas 44a, 44b, 44c indicating the ventilation volume of the path may be provided corresponding to the arrows 44B-1, 44B-2, 44B-3 respectively indicating the path. For example, since the office room 41 is adjacent to the corridor 44, and the value obtained by subtracting the exhaust rate from the air supply rate is 800 m ³ / h in the office room 41, the ventilation volume of the path is in the vicinity of the arrow 44B-1. “800 m ³ / h” indicating is displayed. Similarly, in consideration of the air supply / discharge of WC (M) 42, “450 m ³ / h” indicating the ventilation volume of the path is displayed near the arrow 44B-2. Further, in consideration of the air supply amount / displacement amount of WC (W) 43, “350 m ³ / h” indicating the ventilation amount of the path is displayed in the vicinity of the arrow 44B-3.

  Room No. An arrow 45B-1 displayed in the machine room 45 of No. 5 indicates an air supply path of the machine room 45, and is displayed by a broken line representing a path, for example. An arrow 45B-2 indicates an exhaust path of the machine chamber 45, and is displayed, for example, by a dashed dotted line representing the mechanical exhaust. That is, in the machine room 45, arrows 45B-1 and 45B-2 indicating two ventilation paths are displayed with different line types.

  Thus, the user can easily visually recognize the ventilation path of each room by displaying a plurality of arrows indicating the ventilation path corresponding to each room in the air balance diagram 40. Also, the arrow indicating the ventilation route is displayed in a form that distinguishes the air supply, the exhaust, or the path, so that the user can easily visually recognize which of the air supply, the exhaust, or the path corresponds to each ventilation route. be able to.

  FIG. 6 is a flowchart for explaining the ventilation design method according to the present embodiment. The ventilation calculation process as the ventilation design method is executed by the control unit 2A, and various data stored in the storage unit 3 or the server 10 are read out according to each step of the ventilation calculation process.

  First, from the server 10 that can communicate via the input unit 4 or the communication I / F 7, each room No. 1 to No. A plurality of pieces of room information on 5 are acquired (step S11). The room information is, for example, information read from the server 10, such as floor, room name, floor area, ceiling height, floor height, etc. (BIM information), and information using BIM information, for example, building use, room use, air conditioning target It includes room information (BIM ZONE information).

  Next, based on the acquired plurality of pieces of room information, ventilation calculation conditions of each room can be set (step S12). For example, room number no. In (1), since the room application is the office, using the ventilation calculation method by general ventilation, the amount of fresh external air required for one person based on the amount of carbon dioxide contained in the storage personnel and human breath, prevention of a sick house, etc. Set the ventilation calculation conditions in consideration of the required ventilation frequency etc. based on the hygiene aspect. Room No. 2 and No. Since the room use is a toilet, 3 sets the ventilation calculation conditions from the necessary number of times of ventilation etc. required for the exhaustion of odor using the ventilation calculation method by general ventilation. Room No. 5 is a machine room such as an electric machine room, so that the ventilation calculation condition is set according to the calorific value emitted from the machine. The setting of the ventilation calculation condition may not necessarily be performed, and the step S12 can be omitted by fixing to the default ventilation calculation method according to the application of the room.

Then, based on the plurality of pieces of room information acquired in step S11 and the ventilation calculation conditions acquired in step S12, each room No. 1 is obtained. 1 to No. The necessary ventilation volume of 5 is calculated (step S13). For example, the room numbers No. 1 and 2 shown in FIGS. In case of 1 office room 41, general ventilation is based on room name, floor area, information about ceiling height and ventilation calculation condition (the necessary number of people, required ventilation per person, required ventilation frequency for prevention of sick house etc.) The required ventilation rate is calculated to be 1800 m ³ / h using the ventilation calculation method according to Similarly, all the room numbers to be subjected to the ventilation calculation. 1 to No. Determine the required ventilation rate of 5. When the above step S12 is omitted, the control unit 2A uses the predetermined ventilation calculation method based on the plurality of pieces of room information acquired in step S11, for example, the room name and the floor area, and sets each room No. 1 to No. The required ventilation rate of 5 can be calculated.

  Next, each room No. calculated in step S13. 1 to No. Based on the required ventilation volume of 5, the ventilation calculation table 30 of the building shown in FIG. 4 is created (step S14).

  Furthermore, the CAD drawing of the building obtained from the BIM information is acquired from the server 10 that can communicate via the input unit 4 or the communication I / F 7, and the room No. 1 calculated in step S13 is obtained. 1 to No. The air balance diagram 40 of the building shown in FIG. 5 is created based on the required ventilation rate of 5 and the above-mentioned CAD drawing of the building (step S15).

  FIG. 7 is a flowchart for explaining the air balance diagram creation process of step S15 in FIG. 6, and FIGS. 8 (a) to 8 (d) are diagrams for explaining each step of the air balance diagram creation process of FIG. It is. This air balance diagram creation processing is executed by the control unit 2A, as in the ventilation calculation method described above.

  First, each room in the CAD drawing obtained from the BIM information is displayed separately for each ventilation type (step S21) (FIG. 8A). For example, since office room 41 on the third floor is type 1 ventilation, it is displayed as a thin dot, and WC (M) 42, WC (W) 43 and machine room 45 are all type 3 ventilation, so they are dark dots. Since the corridor 44 does not correspond to any of the ventilation types, it is indicated by hatching. Moreover, the space 46 which is not the target of the ventilation calculation is displayed in white.

  Next, the ventilation amount and the machine number of the ventilator are displayed on the display area of each room displayed in the CAD drawing (step S22) (FIG. 8 (b)). For example, display area 41A corresponding to office room 41 is displayed, and room No. 1 is displayed in display area 41A. 1. Display the ventilation volume (OA), ventilation volume (EA), ventilation equipment unit number (OA) and equipment number (EA). Similarly, the ventilation volume (OA) and the ventilation volume of each room corresponding to the display areas 42A, 43A, 44A and 45A respectively corresponding to WC (M) 42, WC (W) 43, corridor 44 and machine room 45 (EA), Ventilation equipment machine number (OA) and ventilation equipment machine number (EA) are displayed.

  Next, the plurality of rooms displayed in the CAD drawing are zoned for each ventilation system of the ventilation calculation table 30, and are totaled (step S23) (FIG. 8 (c)). For example, a frame 50 obtained by zoning the office room 41, the WC (M) 42, the WC (W) 43, and the corridor 44, which is the first ventilation system to be subjected to air balance, is displayed. Then, the sum of the air supply amount and the sum of the ventilation amount of the four rooms zoned by the frame 50 are totalized.

  Thereafter, an arrow indicating the ventilation path of each room zoned in the frame 50 is displayed (step S24) (FIG. 8 (d)). For example, for the office room 41, a solid-line arrow 41B-1 and a dashed-dotted arrow 41B-2 are displayed. Similarly to the above, the dashed-dotted arrow 42B and the broken line 44B-2 are displayed for the WC (M) 42, and the dashed-dotted arrow 43B and the broken line 44B-3 are displayed for the WC (W) 43. Then, the broken line 44B-1 is displayed for each of the corridors 44 which become the pass. Furthermore, for the machine room 45, a solid-line arrow 45B-1 and a dashed-dotted arrow 45B-2 are displayed. Each arrow displayed in this step can be moved and edited to an arbitrary position such as the boundary of the outer wall according to an instruction input by the designer.

  Returning to the processing of FIG. 6, after that, the control unit 2A displays both the ventilation calculation table 30 created in step S14 and the air balance diagram 40 created in step S15 on the display unit 6 in real time (step S16). For example, the ventilation calculation table 30 and the air balance diagram 40 are displayed on one screen of the display unit 6 (see FIG. 7). After the process of step S16, the present ventilation design process is ended.

FIG. 9 is a view showing an example of a screen displayed on the display unit 6 of FIG. 1 at step S16 of FIG.
In FIG. 9, the screen 70 includes a window 71 for displaying the ventilation calculation table 30, a window 72 for displaying the air balance diagram 40, and a window 73 for displaying a three-dimensional CAD drawing prepared based on BIM information. . At this time, the display processing unit 26 can select two or all of the window 71 of the ventilation calculation table 30, the window 72 of the air balance diagram 40, and the window 73 of the 3D CAD drawing and can simultaneously display them on the screen 70. . In addition, the display processing unit 26 may select one of the windows 71, 72, 73 and display it on the screen 70, and then switch to another window according to the user's input instruction. it can.

  As described above, according to the present embodiment, the control unit 2A acquires, from the BIM information, a plurality of room information related to each room of the building, and based on the plurality of room information, the necessary ventilation volume of each room of the building Calculate the building ventilation calculation table 30 based on the required ventilation volume of each room, and based on the required ventilation volume of each room and the two-dimensional architectural CAD drawing of the building obtained from the BIM information, Since the air balance diagram 40 of the building concerned is created, it is possible to unify and create the ventilation calculation chart 30 of the building and the air balance chart 40 on the BIM, and the ventilation calculation chart 30 and the air balance chart 40 which are consistent. Can be created simply and quickly.

  Further, the ventilation calculation condition setting unit 22 sets the ventilation calculation condition of each room based on the use information of each room, and the necessary ventilation amount calculation unit 23 determines the room name and floor area of each room and the above-mentioned ventilation calculation condition Since the required ventilation of each room is calculated based on the above, the required ventilation according to the room use of each room can be calculated more accurately.

  In addition, since the display processing unit 26 displays both the ventilation calculation table 30 and the air balance diagram 40 in real time, the user may consider the air balance while looking at both the ventilation calculation table 30 and the air balance diagram 40. This makes it easy to create the air balance diagram 40, and the convenience can be improved.

FIG. 10 is a diagram showing a modification of the control unit 2A of FIG. In FIG. 10, the same functional blocks as in FIG. 3 will be assigned the same reference numerals and descriptions thereof will be omitted.
10, the control unit 2B is similar to the control unit 2A of FIG. 3 in that the room information acquisition unit 21, the required ventilation amount calculation unit 23, the ventilation calculation table creation unit 24, the air balance diagram creation unit 25, and the display processing unit 26. In addition to these, the display information changing unit 27, the ventilator information transmitting unit 28, and the output processing unit 29 are further included.

  The display information changing unit 27 rearranges the ventilation related information corresponding to a plurality of rooms of the building in the ventilation calculation table 30 displayed by the display processing unit 26 for each ventilation system. For example, the display information changing unit 27 targets the plurality of rooms on the third floor in the ventilation calculation table 30, and inputs "301" to the room belonging to the first ventilation system to be subjected to air balance, that is, the ventilation system It is possible to sort and display the rooms where the air balance is present and the rooms not subject to air balance, that is, the rooms in which "-" is input to the ventilation system. The display information changing unit 27 can also sort and display only the rooms belonging to the first ventilation system to be subjected to air balance.

  Further, the display information changing unit 27 is a dot or hatching indicating the ventilation type of each room in the air balance diagram 40 displayed by the display processing unit 26, a ventilation amount or ventilation equipment displayed in a display area corresponding to each room, And the position and direction of the arrow indicating the ventilation path of each room, the line type and the like can be changed according to the user's change instruction input. In addition, the display information changing unit 27 can adjust the range of zoning with the frame 50 in accordance with the user's change instruction input.

  The ventilation device information transmission unit 28 transmits a part of the ventilation related information included in the ventilation calculation table 30 to the outside. For example, the ventilation device information transmission unit 28 includes the room name, the air supply amount (OA), the exhaust amount (EA), the ventilation device (OA), the ventilation device (EA), the machine number (OA). Unit number (EA), route (OA) and route (EA) can be transmitted outside for each ventilation system.

  The storage processing unit 29 stores the ventilation calculation table 30 and the air balance diagram 40 in the storage unit 3 in association with each other. The memory processing unit 29 may associate the ventilation calculation table 30 and the air balance diagram 40 and transmit the ventilation calculation table 30 and the air balance diagram 40 in order to store the ventilation calculation table 30 and the air balance diagram 40 outside the server 10 or the like.

  FIG. 11 is a flowchart for explaining a modification of the ventilation design method according to the present embodiment. The ventilation design method of FIG. 11 is executed by the control unit 2B, and various data stored in the storage unit 3 or the server 10 are read according to each step of the ventilation calculation process. In FIG. 11, the same steps as those in FIG.

  In FIG. 11, after step S16, the ventilation related information corresponding to a plurality of rooms in the ventilation calculation table 30 displayed on the display unit 6 is rearranged for each ventilation system (step S31).

Next, using the ventilation calculation table 30 rearranged for each ventilation system, adjustment is performed so that the sum of the air supply amount (OA) and the exhaust amount (EA) of the first ventilation system becomes zero (step S32) . For example, the user changes the air supply amount, the air discharge amount, or the path of the ventilation calculation table 30 via the input unit 4 while looking at the ventilation calculation table 30 and the air balance diagram 40 displayed on the display unit 6 And the control unit 2 changes the air supply amount (OA) / the exhaust amount (EA) etc. displayed in each display area of the air balance diagram 40 based on the input change instruction input. be able to. For example, when a value obtained by subtracting the sum of exhaust amount (EA) from the sum of air supply amount (OA) of the first ventilation system is larger than 0, at least one of the air supply amounts (OA) in the plurality of chambers The air balance can be achieved by reducing or by increasing at least one of the displacements (EA) in the plurality of chambers.
Specifically, the user can adjust and determine the air supply (OA) and the exhaust (EA) while looking at the required ventilation and the air balance of each ventilation system. For example, in the case of the first ventilation system “301” shown in FIGS. 4 and 5, since the sum of the displacements of WC (M) 42 and WC (W) 43 is 800 m ³ / h the 800 m ³ / h of the gas has been 1800 m ³ / h, is supplied as the path to the WC (M) 42 and WC (W) 43 through the corridor 44. Therefore, the overall air balance is set to 0 by reducing the displacement of the office room 41 from 1800 m ³ / h to 1000 m ³ / h and supplying the excess exhaust (800 m ³ / h) as a path to the corridor.
In addition, even if the air balance is not obtained in the initial stage or after adjustment in the first ventilation system that is the object of air balance, even if an error display indicating that the air balance is not obtained is performed on the screen 70 Good. In the case of a design that does not take an air balance, the error display can be set so as not to be performed.

  Next, the ventilation calculation table 30 and the air balance diagram 40 are output through the output unit 5 (step S33). At this time, various output forms such as data output and print output can be selected. In addition, the control unit 2 stores in advance the predetermined form of the ventilation statement and the air balance chart in the storage unit 3, and outputs the predetermined form from the storage unit 3 when outputting the ventilation statement and the air balance chart. It is possible to read out the ventilation calculation table 30 and the air balance diagram 40 in a predetermined format and then output.

  Then, if necessary, part of the ventilation related information included in the ventilation calculation table 30, for example, room name, air supply (OA), exhaust (EA), ventilator (OA), ventilator (EA), The machine number (OA), the machine number (EA), the route (OA) and the route (EA) are transmitted to the outside such as the server 10 (step S34). As a result, it is possible to easily create a ventilation device and a rough list including detailed information of the ventilation device and the structure using a building design format and the like.

  In the present step S34, the control unit 2 creates a ventilation device / dagger selection table based on the name of the ventilator selected in the ventilation calculation table 30, the machine number of the ventilator, and the model number of the remote, etc. You may transmit an apparatus and a selection list outside.

  Next, the control unit 2B stores the ventilation calculation table 30 and the air balance diagram 40 in association with the storage unit 3 (step S35), and ends the ventilation design process.

  According to this modification, the display information changing unit 27 rearranges the plurality of ventilation related information corresponding to the plurality of rooms of the building in the ventilation calculation table 30 displayed by the display processing unit 26 for each ventilation system. This allows the user to perform air balance tabulation at a glance, making it possible to create an air balance diagram accurately and easily.

  In addition, while the user looks at the ventilation calculation table 30 and the air balance chart 40 displayed on the screen 70 of the display unit 6, the air supply amount (OA) and the discharge amount (EA of each room displayed in the ventilation calculation table 30) The sum of the air supply amount (OA) and the exhaust amount (EA) of the first ventilation system to be air-balanced can be made zero by simple adjustment such as changing the numerical value of). Therefore, the user can easily perform the air balance design, and furthermore, the contents changed in one of the ventilation calculation table 30 and the air balance diagram 40 can be automatically reflected on the other, and the air balance diagram 40 Can be created more easily.

  In addition, since the output processing unit 29 outputs the ventilation calculation table 30 and the air balance diagram 40, the document can be created easily and quickly when submission of a building ventilation statement or an air balance diagram is required by measures such as sick house measures. can do.

  Although the ventilation design apparatus and the ventilation design method according to the embodiment of the present invention have been described above, the present invention is not limited to the described embodiment, and various modifications and changes may be made based on the technical concept of the present invention.
