Description

The present invention relates to a design support system that provides design support when introducing an air conditioning system in a building.

Buildings such as houses may be provided with an air-conditioning system for the entire building using a common air-conditioning device (see, for example, Patent Document 1). In the whole building air-conditioning system, the air-conditioning device installed in the machine room takes in the air in the machine room and generates air-conditioning air (that is, cold air or warm air), and transfers the generated air-conditioning air to a plurality of rooms to be air-conditioned. It is designed to be supplied via a ventilation duct. In this case, each room to be conditioned is provided with an outlet (outlet) for blowing out conditioned air on the ceiling or the like, and the conditioned air is supplied to these outlets through a ventilation duct. Then, the supplied conditioned air is blown out from each outlet to the room to be air-conditioned, and the blown-out conditioned air is used to cool and heat each room.

In a building equipped with an air-conditioning system in the entire building, a return path (return path) is generally provided in which the air-conditioned air supplied to each room returns (returns) to the machine room. This reflux path is a path that passes through a ventilation portion (vent) formed between adjacent rooms, and this ventilation portion is formed by, for example, an undercut portion of an entrance / exit door. In this case, the air conditioner has a return air portion that takes in the air returned to the machine room, and generates air conditioning air based on the air taken in from the return air portion. Therefore, in this case, the air conditioning of each room is performed while circulating the air conditioning air in the building.

By the way, in the above-mentioned circulation type conditioned whole building air-conditioning system, when the conditioned air blown out from each outlet returns to the machine room through the recirculation path, it is conceivable that the recirculated conditioned air merges in the middle. In this case, when the merged conditioned air flows through the ventilation section between adjacent rooms, it is considered that the amount of conditioned air passing through the ventilation section increases, so that a wind noise may be generated when the conditioned air passes through. ..

Therefore, in order to suppress the generation of wind noise, it is conceivable to increase the opening area (ventilation opening area) for each ventilation portion in the building. However, if this is done, the opening area will be increased even for the ventilation part that does not originally need to have a large opening area, such as the ventilation part where the amount of air-conditioned air passing through is small, so that light leakage and design through the ventilation part will occur. The problem of deterioration of sex is likely to occur.

In addition, when introducing an air-conditioning system for the entire building into a building, it is conceivable to determine which ventilation part produces wind noise in the building and to increase the opening area only for that ventilation part. However, since the return path of the conditioned air is different for each building floor plan, it is considered difficult to take such a measure for each building.

The present invention has been made in view of the above circumstances, and provides a design support system capable of designing an appropriate return path according to the floor plan of a building when introducing an air conditioning system in the entire building. Is the main purpose.

Therefore, in the indoor space where the return air portion is provided, it is assumed that the conditioned air that has flowed in is pushed out of the indoor space through the ventilation portion by the positive pressure, and it is conceivable that a wind noise is generated at that time. Therefore, in view of this point, in the present invention, a ventilation portion included in the reflux path created on the floor plan screen is provided in the partition portion for partitioning the return air space portion (indoor space in which the return air installation position is set). It is determined whether it is the first ventilation portion or the second ventilation portion provided in the other partition portion, and the type of the ventilation portion is determined based on the result of the determination. In this case, when the ventilation portion is the first ventilation portion, the generation of wind noise can be suitably suppressed by setting the type to have a relatively large opening area.

The position) and the installation position of the return air unit (return air installation position) are set. In this case, since the blowout installation position and the return air installation position are automatically set according to the floor plan of the building, the work can be facilitated in designing the return path. Then, when the outlet installation position and the return air installation position are set, a reflux path is created on the floor plan information from the outlet installation position to the return air installation position for each outlet installation position, and the created reflux is created. Based on the routes, the number of reflux routes that pass through the vents is determined for the vents included in those reflux routes.

Specifically, as shown in FIG. 4B, the air conditioner setting unit 43 displays the icon 21a of the air conditioner 21 on the floor plan screen C. The icon 21a is moved to and arranged at the installation position of the air conditioner 21 on the floor plan screen C by a drag operation by the user's operation unit 32 (specifically, a mouse). Then, when the icon 21a is arranged on the floor plan screen C, the air conditioner setting unit 43 sets the arranged portion as the air conditioning installation position. In this embodiment, the air conditioner installation position is set in the machine room 18 (see FIG. 4B).

Further, as described above, the air conditioner 21 has an intake unit 23 that takes in the conditioned air flowing into the machine room 18 as return air. Therefore, by setting the installation position (air conditioning installation position) of the air conditioner 21 on the floor plan screen C in the air conditioner setting unit 43, the installation position of the intake unit 23 (corresponding to the return air unit) on the floor plan screen C. Will also be set. Therefore, in this case, the air conditioner setting unit 43 can also be referred to as a return air unit setting means for setting the installation position of the return air unit on the floor plan screen C. Further, here, since the installation position of the intake unit 23 (return air unit) is set in the machine room 18, the machine room 18 corresponds to the return air space unit.

Based on the operation of the operation unit 32 by the user, the air outlet setting unit 44 sets the installation positions (outlet installation positions) where the air outlet 22 is installed on the floor plan screen C at a plurality of locations. Specifically, as shown in FIG. 5C, the air outlet setting unit 44 displays a plurality of icons 22a of the air outlet 22 on the floor plan screen C. For example, when the number of outlets 22 to be installed is input by the user by the operation of the operation unit 32, the outlet setting unit 44 displays the icons 22a corresponding to the input number on the floor plan screen C. These icons 22a are moved and arranged at the installation positions of the air outlets 22 on the floor plan screen C by a drag operation by the user's operation unit 32 (specifically, a mouse). Then, when the icons 22a are arranged on the floor plan screen C, the outlet setting unit 44 sets each of the arranged locations as the outlet installation position.

Based on the above, a reflux path S is created on the floor plan screen C so as to reach the air conditioning installation position from the air conditioner installation position for each outlet installation position. As a result, as shown in FIG. 5D, each of the created reflux paths S is displayed on the floor plan screen C. Specifically, the reflux path creating section 45 creates the reflux path S so as to pass through the indoor space and the ventilation section 25 on the floor plan C (in other words, not to pass through the partition section 19). In the following, in order to distinguish each of the created reflux paths S, each of the reflux paths S will also be referred to as a reflux path S1 to S6, respectively. Further, the reflux route creating unit 45 corresponds to the reflux route creating means.

In the example of FIG. 5D, the reflux path S created by the reflux path creation section 45 includes a plurality of (specifically, three) ventilation sections 25 (hereinafter, referred to as ventilation sections 25a to 25c). .. Then, the route number determination unit 46 determines the number of reflux routes S passing through the ventilation portions 25a to 25c for each of the ventilation portions 25a to 25c.

Specifically, in the example of FIG. 5D, of the ventilation portions 25a to 25c, the ventilation set in the partition portion 19 between the washroom 15 and the kitchen 13 (specifically, the corridor leading to the kitchen 13). Of the reflux paths S1 to S6, only the reflux path S1 passes through the portion 25a. Further, in the ventilation portion 25b set in the partition portion 19 between the living / dining room 12 (specifically, the corridor leading from the living / dining room 12) and the entrance hall 11, five return paths S1 to 5 of the return paths S1 to S6 are provided. S5 is passing through. Further, all of the return paths S1 to S6 pass through the ventilation portion 25c set in the partition portion 19 between the entrance hall 11 and the machine room 18. Therefore, the path number determination unit 46 determines that the number of reflux paths S passing through the ventilation section 25a is 1, the number of reflux paths S passing through the ventilation section 25b is 5, and the ventilation section 25c is determined to be 5. The number of reflux routes S passing through is determined to be 6. The route number determination unit 46 corresponds to the route number determination means.

In the ventilation unit position determination unit 47, the ventilation units 25a to 25c included in the reflux path S created by the reflux path creation unit 45 are provided in the partition portion 19 for partitioning the machine room 18 which is the return air space portion. It is determined whether it is a 1 vent or a second vent provided in the other partition 19. In the example of FIG. 5D, among the ventilation portions 25a to 25c, the ventilation portion 25c is determined to be the first ventilation portion, and the ventilation portions 25a and 25b are determined to be the second ventilation portions. The ventilation unit position determination unit 47 corresponds to the ventilation unit position determination means.

In the number determination unit 48, the number of first ventilation units included in each reflux path S (in other words, total reflux path S) created by the reflux path creation unit 45 is based on the determination result of the ventilation section position determination unit 47. Determine if there is one or more. In the example of FIG. 5D, since the first ventilation portion is only the ventilation portion 25c, it is determined that the number of the first ventilation portions is one. The number determination unit 48 corresponds to the number determination means.

Based on the determination results of the number of paths determination unit 46, the ventilation unit position determination unit 47, and the number determination unit 48, the ventilation unit type determination unit 49 sets the types of the ventilation units 25a to 25c to a plurality of types having different opening areas. Select from the ventilation section candidates of. FIG. 6 shows a plurality of types of ventilation unit candidates, and first, these ventilation unit candidates will be described below. As shown in FIGS. 6A to 6D, in the present embodiment, four types of ventilation unit candidates are defined as ventilation unit candidates, and the storage unit 34 contains information on these ventilation unit candidates in advance. It is remembered. Candidates for the ventilation portion include an undercut portion A formed under the door (see FIG. 6A) and a door slit portion B formed in the door (see FIG. 6B), which are arranged vertically. There are an inclined louver C (see FIG. 6 (c)) and a horizontal louver D (see FIG. 6 (d)) having a plurality of slats. Each of these ventilation portion candidates A to D has an opening (ventilation opening) capable of ventilating. In the undercut portion A, an opening is formed by the undercut portion A, and in the door slit portion B, an opening is formed by the slit portion B. Further, in the inclined louver C and the horizontal louver D, an opening that allows ventilation is formed by each gap between the vertically adjacent slats.

The openings of the ventilation portion candidates A to D are different from each other in the opening area. Specifically, the opening areas of the ventilation portion candidates A to D are larger in the door slit portion B than in the undercut portion A and in the inclined louver C than in the door slit portion B. , The horizontal louver D is larger than the inclined louver C (A <B <C <D). Therefore, among the ventilation unit candidates A to D, the ventilation unit candidate having the largest opening area is the horizontal louver D.

In addition to the inclined louver C and the horizontal louver D, in the inclined louver C, slats are arranged vertically on both sides in the thickness direction. Each of these slats is arranged in an inclined direction with respect to the horizontal direction. Specifically, the slats arranged on both sides of the inclined louver C in the thickness direction are opposite to each other in the inclined direction. In the inclined louver C, since each slat is inclined, light leakage is less likely to occur as compared with the horizontal louver D, which is advantageous in terms of design. Further, in the horizontal louver D, slats are arranged only on one side of both sides in the thickness direction. In the horizontal louver D, each slat is arranged in a horizontal orientation, whereby the gap between the slats (and thus the opening area) is made larger than that of the inclined louver C. The inclined louver C and the horizontal louver D are provided on the door in the partition portion 19 or are provided on the partition wall above the door.

Subsequently, the ventilation unit type determination process executed by the ventilation unit type determination unit 49 will be described with reference to the flowchart shown in FIG. 7. In the ventilation unit type determination unit 49, the ventilation unit type determination processing is executed in order for each ventilation unit 25a to 25c. Further, the ventilation unit type determination unit 49 corresponds to the ventilation unit type determination means.

As shown in FIG. 7, first, in step S11, based on the determination result of the ventilation unit position determination unit 47, the ventilation portions 25a to 25c (hereinafter, also referred to as the target ventilation portion) to be processed by the ventilation unit type determination processing. Is a first vent or a second vent. If the target ventilation portions 25a to 25c are the first ventilation portions, the process proceeds to step S12, and if the target ventilation portions 25a to 25c are the second ventilation portions, the process proceeds to step S15. Here, among the ventilation portions 25a to 25c, the ventilation portion 25c is the first ventilation portion and the ventilation portions 25a and 25b are the second ventilation portions. Therefore, when the target ventilation portion is the ventilation portion 25c, the step is performed. The process proceeds to S12, and if the ventilation portions 25a and 25b, the process proceeds to step S15.

In step S15, the type of the second ventilation unit is selected and determined from the respective ventilation unit candidates A to D based on the determination result in the number of routes determination unit 46. That is, in this step, the type of the second ventilation part is selected as each ventilation part candidate A based on the number of reflux paths S passing through the second ventilation parts (vention parts 25a and 25b) determined by the path number determination unit 46. Select from ~ D to decide. Specifically, in this step, when the number of reflux paths S passing through the second ventilation portion is 1 or 2, the undercut portion A is selected from the ventilation portion candidates A to D, and the undercut portion A is selected. Part A is determined as the type of the second ventilation part. When the number of reflux paths S passing through the second ventilation portion is 3 or 4, the door slit portion B is selected, and the door slit portion B is determined as the type of the second ventilation portion. Further, when the number of reflux paths S passing through the second ventilation portion is 5 or more, the inclined louver C is selected, and the inclined louver C is determined as the type of the second ventilation portion. In the example of FIG. 5D, the second venting portion is the venting portion 25a and the venting portion 25b, and among these venting portions 25a and 25b, the number of reflux paths S passing through the venting portion 25a is one. The number of reflux paths S via the ventilation portion 25b is five. Therefore, the type of the ventilation portion 25a is determined to be the undercut portion A, and the type of the ventilation portion 25b is determined to be the inclined louver C.

In step S12, it is determined whether there is one or a plurality of first ventilation units based on the determination result of the number determination unit 48. Then, in the following steps S13 and S14, the type of the first ventilation portion (ventilation portion 25c) is selected and determined from the ventilation portion candidates A to D based on the determination result. Specifically, when there is one first vent, a horizontal louver D is selected from the candidates A to D of the vents, and the horizontal louver D is determined as the type of the first vent (1). Step S13). When there are a plurality of (for example, two) first ventilation portions, an inclined louver C is selected from the respective ventilation portion candidates A to D, and the inclined louver C is determined as the type of the first ventilation portion. (Step S14). In the example of FIG. 5D, since the first ventilation portion is one ventilation portion 25c, the type of the ventilation portion 25c is determined to be the horizontal louver D. That is, when there is only one first vent, the vent candidate D (horizontal louver) having the largest opening area among the vent candidates A to D as the type of the first vent (vent 25c). D) is selected and decided.

Returning to the description of FIG. 2, the ventilation unit type display unit 50 causes the display unit 33 to display the types of the ventilation units 25a to 25c determined by the ventilation unit type determination unit 49. In this case, the ventilation unit type display unit 50 displays the types of the ventilation units 25a to 25c in characters (text) or in a figure (for example, a figure as shown in FIG. 6).

According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

When the floor plan information of the building 10 into which the entire building air conditioning system 20 is introduced is acquired, the acquired floor plan information is displayed on the display unit 33 as the floor plan screen C. On the floor plan screen C, the installation position of each outlet 22 (air-conditioning installation position) and the installation position of the air conditioner 21 (intake unit 23) (air-conditioning installation position) are set based on the user's operation. When each installation position is set, a reflux path S (S1 to S6) is created on the floor plan screen C so as to reach the air conditioning installation position (in other words, the return air installation position) from the outlet installation position for each outlet installation position. NS.

When each reflux path S is created, the number of reflux paths S via the vents 25a to 25c is determined for the vents 25a to 25c included in the reflux paths S based on the created reflux paths S. Will be done. Then, based on the result of the determination, the type of the ventilation portions 25a to 25c is selected and determined from a plurality of types of ventilation portion candidates A to D having different opening areas. As a result, when the number of reflux paths S passing through the ventilation portions 25a to 25c is large, that is, when it is considered that the amount of conditioned air flowing through the ventilation portions 25a to 25c is large, the type of the ventilation portions 25a to 25c Can be determined by selecting ventilation unit candidates A to D having a large opening area. Therefore, it is possible to suppress the generation of wind noise in the ventilation portions 25a to 25c. Further, when the number of reflux paths S passing through the ventilation portions 25a to 25c is small, that is, when it is considered that the amount of conditioned air flowing through the ventilation portions 25a to 25c is small, the type of the ventilation portions 25a to 25c is selected. Candidates A to D for ventilation portions having a small opening area can be selected and determined. Therefore, it is possible to suppress problems such as light leakage and deterioration of design in the ventilation portions 25a to 25c. As described above, according to the present design support system, the ventilation portions 25a to 25c included in the return path S are set to have an appropriate opening area according to the floor plan of the building 10 in which the entire building air conditioning system 20 is introduced. It becomes possible. Therefore, it is possible to design an appropriate return path S according to the floor plan of the building.

Since the machine room 18 in which the air conditioner 21 (intake unit 23) is provided is a space into which the conditioned air blown out from each outlet 22 flows in, it is considered that the pressure tends to be positive as compared with other indoor spaces 11 to 17. Be done. Therefore, in the machine room 18, it is assumed that the conditioned air that has flowed in is pushed out of the machine room 18 through the ventilation unit 25 by a positive pressure, and it is conceivable that a wind noise is generated at that time.

Therefore, in the above embodiment, in view of this point, the ventilation portions 25a to 25c included in the return path S created on the floor plan screen C are the machine room 18 (return air space portion) in which the return air installation position is set. It is determined whether it is the first ventilation portion provided in the partition portion 19 for partitioning the above, or the second ventilation portion provided in the other partition portion 19, and based on the result of the determination, the ventilation portion 25a is determined. The type of ~ 25c is determined. Specifically, when the ventilation portions 25a to 25c are the first ventilation portions, the ventilation portions 25a to 25c are selected from the ventilation portion candidates A to D having a relatively large opening area. I am going to choose a certain louver C, D. As a result, when the ventilation portions 25a to 25c are the first ventilation portions (in the above embodiment, the ventilation portions 25c are the first ventilation portions), the type is set to have a relatively large opening area. Therefore, the generation of wind noise can be suitably suppressed.

By the way, when the number of the first ventilation portions provided in the partition portion 19 for partitioning the machine room 18 (return air space portion) is one, compared with the case where the number of the first ventilation portions is a plurality. It is considered that when the conditioned air flows into the machine room 18, the pressure tends to be positive. Therefore, it is considered that wind noise is likely to be generated in the machine room 18. Therefore, in the above embodiment, in consideration of this point, it is determined whether the number of the first ventilation portions is one or a plurality, and the type of the first ventilation portion is determined based on the result of the determination. I try to do it. As a result, when the number of the first ventilation portions (in the above embodiment, the first ventilation portion is the ventilation portion 25c) is one, the type of the first ventilation portion is set to have a large opening area. The generation of wind noise can be suitably suppressed.

Specifically, when the number of the first ventilation portions is one, it is decided to select and determine the ventilation portion candidate D having the largest opening area among the plurality of types of ventilation portion candidates A to D. As a result, when the number of the first ventilation portions is one, the generation of wind noise can be reliably suppressed.

More specifically, since the ventilation portion candidate D having the largest opening area is a horizontal louver D, when the number of first ventilation portions is one, light leakage and deterioration of design are suppressed. , The generation of wind noise can be reliably suppressed.

The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

In the above embodiment, the case where the number of the first vents included in each reflux path S created by the reflux path creation unit 45 is one has been described as an example, but the number of the first vents is large. It can be assumed that there are more than one. FIG. 8 shows a building 60 having substantially the same floor plan as the building 10. In this building 60, two ventilation portions 25 are set in the partition portion 19 for partitioning the machine room 18. These ventilation portions 25 are provided in each of the partition portions 19 facing each other across the machine room 18, and the ventilation portion 25c of the ventilation portions 25 is set in the partition portion 19 between the entrance hall 11 and the machine room 18. , The ventilation portion 25d is set in the partition portion 19 between the washroom 15 and the machine room 18.

In FIG. 8, each return path S created by the return path creation unit 45 is also shown on the floor plan of the building 60. In the example of FIG. 8, among the reflux paths S, the reflux path S from the outlet 22 of the washroom 15 passes through the ventilation section 25d, and the reflux path S from the other outlets 22 passes through the ventilation section 25c. doing. In this case, since the ventilation portions 25c and 25d are provided in the partition portion 19 that partitions the machine room 18, they are the first ventilation portions, respectively. Therefore, in the example of FIG. 8, each of the created reflux paths S includes two first ventilation portions. Therefore, in this example, in step S12 of FIG. 7, it is determined that there are a plurality of first vents, and as a result of the determination, each of the first vents (each vent 25c, 25d) is classified as the type. The inclined louver C is selected and determined from the ventilation portion candidates A to D (step S14).

-In the above embodiment, when the ventilation portions 25a to 25c included in the created reflux path S are the first ventilation portions, the first ventilation portion is based on whether there is one or a plurality of the first ventilation portions. The type of the first vent is determined, but this may be changed. For example, even when the vents 25a to 25c included in the created reflux path S are the first vents, the number of reflux paths S via the first vents is the same as in the case of the second vents. The type of the first venting portion may be determined based on the above. Even in that case, if the number of reflux paths S passing through the first ventilation section is large, that is, if the amount of conditioned air passing through the first ventilation section is considered to be large, the type of the first ventilation section is used. Therefore, by selecting and determining a ventilation portion candidate having a large opening area, it is possible to suppress the generation of wind noise in the ventilation portion.

-In the above embodiment, the ventilation unit type determination unit 49 determines the types of the ventilation units 25a to 25c by selecting from four types of ventilation unit candidates A to D having different opening areas. Candidates A to D do not necessarily have to be four types, but may be two types, three types, or five or more types. For example, when there are three types of ventilation unit candidates, either the undercut portion A or the door slit portion B may be excluded from the ventilation unit candidates from the four types of ventilation unit candidates A to D of the above embodiment. Conceivable.

-In the above embodiment, the case where the intake unit 23 (return air unit) is provided in the air conditioner 21 has been described as an example, but the intake unit (return air unit) is provided in the air conditioner 21. However, it may be installed in a place different from the air conditioner 21. For example, it is conceivable that the return air portion is set as a return air port (return air grill) on the ceiling or floor of the indoor space. In that case, the return air port is connected to the air conditioner 21 via a ventilation duct. In such a configuration, the conditioned air blown out from each outlet 22 is taken into the return air port as return air, and the taken-in return air is supplied to the air conditioner 21 via the ventilation duct. Then, conditioned air is generated in the air conditioner 21 based on the supplied return air.

When the return air port is such a return air port, instead of the air conditioner setting unit 43 described above, the installation position (return air installation position) where the return air port is installed is set according to the user's operation. A return air port setting unit (corresponding to the return air unit setting means) to be set on the screen C may be provided. Then, based on the return air port or the like set by the return air port setting unit, a return path may be created on the floor plan screen C so as to reach the return air port.

-In the above embodiment, the floor plan information of the building 10 acquired by the floor plan information acquisition unit 41 does not include information on what kind of ventilation unit 25 is used, but such information is provisional. It may be included as information (default information). For example, it is conceivable to include information that the type of each ventilation portion 25 is the undercut portion A as temporary information. In this case, when the ventilation unit type determination unit 49 determines the type of the ventilation unit 25, the type of the ventilation unit 25 is replaced with the type determined by the determination unit 49 from the undercut portion A.

In the above embodiment, the air conditioner setting unit 43 sets the air conditioning installation position on the floor plan screen C displayed on the display unit 33 based on the operation by the user, and the air outlet setting unit 44 also performs the operation by the user. Based on this, the air conditioner installation position was set on the floor plan screen C, but this may be changed. For example, in the air conditioner setting unit, the air conditioning installation position is set on the floor plan information based on the floor plan information of the building 10 acquired by the floor plan information acquisition unit 41, and the floor plan information of the building 10 also acquired in the air outlet setting unit. Based on the above, it is conceivable to set the outlet installation position on the floor plan information. In this case, since the air conditioner installation position and the blowout installation position are automatically set according to the floor plan of the building 10, the work can be facilitated in designing the reflux path.

When setting the air conditioner installation position and the blowout installation position as described above, it is not always necessary to display the floor plan screen C of the building 10 on the display unit 33. In that case, the return route creation unit 45 creates the return route on the floor plan information (non-display information) of the building 10 acquired by the floor plan information acquisition unit 41.

Further, when setting the air conditioner installation position and the blowout installation position based on the floor plan information of the building 10, for example, based on the floor plan information of the building 10, the air conditioner installation position is set in the machine room of each indoor space in the building 10. It is conceivable to set the installation position of the air conditioner in the living room space. More specifically, when setting the blowout installation positions, for example, the number of blowout installation positions is set according to the area of the living room space, and the placement positions of the blowout installation positions are set (for example, predetermined intervals are set in advance). It is possible to set it (open). Further, when setting the blowout installation position, for example, the blowout installation position may be set near the window.

-In the above embodiment, the design support system in the present invention is configured by one device (specifically, the design support device 30), but by changing this, a plurality of devices connected to each other via a network such as the Internet. It may be configured by an apparatus. For example, it is conceivable that the design support system includes a design device having a design function of the building and a design support device having a design support function when introducing the whole building air conditioning system into the building. In this case, the building 10 is designed by the design device, and the design data of the designed building 10 is taken in (transmitted) to the design support device through the network. Then, it is conceivable that the design support device acquires the floor plan information of the building 10 based on the captured design data, and performs the design support process (FIG. 2) based on the acquired floor plan information.
