Next, the operation of the floor cooling / heating design support system 1 will be described.
FIG. 4 is a flowchart showing the overall operation of the floor cooling / heating design support system 1.
First, in step S101, customer information is registered. Items necessary as customer information are displayed on the monitor 4, and the user inputs customer information from the keyboard 5 or the like for each item. The items of customer information are, for example, a house name, an adjacent district, a zip code, an address, and a building hierarchy.
FIG. 5 is a diagram showing a display example of the monitor 4 at step S101. The item of customer information is displayed on the monitor 4, and the control unit 30 stores the input information in the storage unit 31 as customer information 104.

In step S103, the house floor plan 15 of the house is taken into the personal computer 3. The scanner 7 reads the original floor plans 15a and 15b and converts the original floor plans into image data. The image floor plans 115 a and 115 b converted into image data are stored in the storage unit 31.
FIG. 6 is a diagram showing a screen of the monitor 4 on which the image floor plan 115a is displayed.
Hereinafter, a case where the floor plan 15a is captured by the scanner 7 and the image floor plan 115a is acquired will be described.

Step S105 is processing for determining the scale of the floor plan 15a from the image floor plan 115a. When the user designates a part where the actual dimension is known in the image floor plan 115a of FIG. 6 and inputs the actual dimension, the scale setting unit 32 calculates the scale of the image floor plan 115a. Here, it is assumed that the outer dimensions of the building are known.
The user first selects a range corresponding to the outside dimension of the building with the mouse 6. The selected range is indicated by a dotted line as a reference floor plan 116a. Next, the vertical dimension 117 a and the horizontal dimension 117 b of the reference floor plan 116 a are input from the keyboard 5 to the personal computer 3.
The scale setting unit 32 calculates the scale of the image floor plan 115a from the size on the image data of the reference floor plan 116a of the image floor plan 115a and the input actual dimension. As a result, the dimensions of the captured drawing can be calculated from the scale.

In step S107, a floor plan for the room where the panel is laid is created.
FIG. 7 is a flowchart for explaining in detail the procedure of creating a floor plan for laying a panel in step S107.
In step S201, work area information is acquired. As an example, an operation in the case where a panel is laid in the Japanese-style room in the image floor plan 115a of FIG. 6 will be described. The user selects the Japanese-style room area with the mouse 6 on the image floor plan 115 a displayed on the monitor 4. Then, the control unit 30 refers to the scale stored in the storage unit 31 and calculates the vertical and horizontal actual dimensions of the Japanese-style room from the vertical and horizontal sizes of the area selected by the mouse 6.
If the Japanese room area selected by the mouse 6 is set so as to overlap with the internal dimensions of the Japanese room, the actual vertical and horizontal dimensions can be calculated more accurately.
In the above description, when the area of the Japanese-style room is selected, the actual dimensions of the Japanese-style room are calculated from the scale. However, the actual dimensions of each area may be input from the keyboard 5.

In step S203, the user inputs the underfloor height of the room and the ceiling height of the room selected in step S201 from the keyboard 5.
In step S203, grid lines (reference lines) 114 are displayed in a grid pattern on the monitor 4 as shown in FIG. 6, and when the vertical and horizontal dimensions of the grid lines 114 are input from the keyboard 5, the intervals between the grid lines are set. Can be changed. Further, the control unit 30 can also display grid lines with a predetermined length corresponding to the scale as a unit of the grid line interval, even if the user does not specify.
Note that the position of the selection area of the room where the panel is laid may be reset according to the displayed grid line.

  After repeating steps S201 to S205 for the number of rooms scheduled to be laid out, in step 207, the information about the respective rooms scheduled to be laid out in steps S201 to S205 is integrated, and panel laying is performed between images on the monitor 4. The panel laying scheduled room is highlighted on the drawing 115a, and the room information of the panel laying scheduled room is displayed on the monitor 4 at the same time.

  In steps S201 to S207, the work area is specified by the mouse 6 or the actual size of the work area is input, but the work area is displayed by an icon or the work area is adjusted by the user by the user. Drawings may be created. For example, an icon group is displayed on the monitor 4 in FIG. 6, and icons corresponding to the type such as the name and size of the room are displayed. When the user selects the “Japanese style room 4.5 tatami” icon 118a with the mouse 6 and drags it to the image floor plan 115a while the image floor plan 115a is displayed, 4 corresponding to the scale of the floor plan is displayed. A work area of 5 tatami mats is displayed. In addition, the room name “Japanese-style room” and a work area simulating a tatami are displayed. This makes it easy to see the image floor plan 115a. Further, the user may change the work area with the mouse 6 as necessary to adjust the size of the Japanese-style room in the image floor plan 115a.

In step S209, a failure area is set. The obstacle area refers to an area where it is impossible to lay a panel, such as a fixed furniture such as a shelf or a bed, an underfloor storage area, etc. With regard to the setting of the failure area, the failure area is designated with the mouse 6 or the failure area displayed after the “failure area” icon is selected is adjusted with the mouse 6 as in the setting of the work area in step S201. To do. Further, similarly to step S205, information on the fault area is input from the keyboard 5 or the like.
Information on the positions and dimensions of the work area and the obstacle area is held in the storage unit 31. In particular, the information regarding the failure area and the information regarding the work area including the failure area are associated with each other.

In step S211 and step S213, the grid line is changed. When the user wants to change the vertical and horizontal intervals of the grid lines, the user selects the “grid / scale setting” icon 118c on the monitor 4 in FIG. 6 and changes the intervals. Regarding the change of the grid line interval, even when the user inputs a new interval from the keyboard 5, the grid line interval may be selected from a plurality of grid line interval candidates displayed on the monitor 4.
Further, if necessary, the image floor plan 115a may be reduced or enlarged so as to match the interval between the grid lines 114.

Further, in step S215, the user inputs room information such as the amount of heat generated from lighting and electrical appliances and the heat capacity for each room where the panel is to be laid. The input information is managed for each room together with the room dimension information obtained in steps S201 and S205, and stored in the storage unit 31.
Here, the information regarding the room where the panel is to be laid is acquired in the order of steps S201, S203, S209, and S215, but may be performed in a different order or may be performed in a single process.

In this way, after creating a floor plan for laying the panel as shown in FIG. 7, a panel laying area is set in step S109.
FIG. 8 is a flowchart for explaining in detail the procedure for setting the panel laying area in step S109. FIG. 9 is a diagram showing a state in which the panel laying area is displayed on the monitor 4 in the room where the panel is to be laid. In FIG. 9, the panel laying areas are M1 to M8 and are indicated by alternate long and short dashed lines. Moreover, let the panel laid for every panel laying area | region be P1-P8.

  In FIG. 8, in step S <b> 301, the panel placement unit 51 determines whether or not to automatically lay the panel in the floor joist direction. When the user selects the automatic placement, the panel placement unit 51 places the longitudinal direction and the joist direction of the panels P1 to P8 having the long side and the short side in step S303. .

  In step S305, the control unit 30 creates a mesh in the panel laying areas M1 to M8, and in step S307, the panel placement unit 51 creates a rectangular frame as a block in the mesh area. In FIG. 9, a mesh 121 and a rectangular frame 123 surrounded by the mesh are displayed in the panel laying area M7. The reason why the panel laying area is divided into meshes like the mesh 121 is to effectively arrange the panels P1 to P8 even when the panel laying area has a shape other than a quadrangle such as a polygon.

In step S309, the panel arrangement unit 51 determines whether or not a failure area exists in the block. A failure region S obtained in Step S2 09 is in the panel laying area, in step S311, from the panel laying region by excluding the fault area S, storing only area capable of laying of the panel as the panel laying area Stored in the unit 31.
Note that the determination of the presence or absence of the failure area S and the exclusion of the portion of the failure area S are performed in units of blocks indicated by the rectangular frame 123.

After setting the panel laying area in step S109, a panel to be laid for each panel laying area is selected and arranged in step S111.
FIG. 10 is a flowchart for explaining in detail the procedure for selecting and arranging the panel in step S111. FIG. 11 is a diagram showing a state where the panel is installed in the room where the panel is scheduled to be installed and further piped on the monitor 4. is there.

  When laying the panels P1 to P8, the panel placement unit 51 determines whether or not placement with a standard panel is possible in step S401. If the arrangement using the standard panel is possible, the standard panel is installed in step S403. The panel placement unit 51 selects an appropriate panel for each panel laying area with reference to room information such as the area of the panel laying area, the dimensions of the panel laying scheduled room, and the heat capacity.

  In step S405, for each panel laying area, it is determined whether or not the laying rate obtained by dividing the total panel area by the panel laying area is 70% or more. If it exceeds 70%, the panel laying in the panel laying area is determined. Is considered to be sufficient and exits. Note that the conditions used to determine whether panel laying in the panel laying area is sufficient may be not the panel area but the heat capacity, the amount of heat generation, and the like, and the laying rate is not limited to 70%. . Also, the condition types and numerical values may be set for each panel laying area.

  On the other hand, when the laying rate does not exceed 70%, in step S407, the panel placement unit 51 determines whether or not the special panel can be placed. A screen prompting manual panel placement is displayed on the monitor 4 and the process ends. If placement by a special panel is possible, a special panel is selected and placed in step S409, and it is determined in step S411 whether the laying rate is 70% or more. If the panel laying ratio using the special panel is 70% or more in step S411, the panel laying calculation in the panel laying area is finished. If the laying ratio does not exceed 70%, the manual panel is used in step S413. A screen prompting the placement is displayed on the monitor 4 and the process is terminated.

As described above, when the panel is selected and arranged in step S111, the monitor 4 displays a state in which the selected panel is arranged in each panel laying area as shown in FIG. The piping is selected and the layout is calculated.
FIG. 12 is a flowchart for explaining in detail the setting procedure of pipes and pipes connecting the panels P1 to P8 and the hot water feeder 201 in step S111.

Hereinafter, for convenience of explanation, it is assumed that two panel laying regions are connected to the hot water feeder 201 as one system.
In step S501, the piping unit 53 selects two panel arrangement areas included in one system and a connection part J in the two panel arrangement areas. The two panel laying areas and the connection portion J are selected based on the positional relationship between the panel laying areas, the heat capacity of the panel laying area, and the like.

In step S503, it is determined whether or not the positions of the two selected connecting portions J are in the same direction. If the position of the connecting portion J is in the same direction as in the connection between the panel P1 and the panel P2 or the connection between the panel P7 and the panel P8, the direction connecting the connecting portions J in step S505 is the X axis direction or Y It is determined whether or not it matches the axial direction, and if they match as in the connection between the panel P7 and the panel P8, the connecting portion J is connected using a straight pipe like the pipe h7 in step S509 and the process ends. To do. The X-axis direction and the Y-axis direction usually indicate the left and right directions and the up and down direction toward the displayed image floor plan, and the walls of buildings and rooms shown in the image floor plan are except for special cases. It is assumed that it is parallel to the X-axis direction or the Y-axis direction.
On the other hand, if the position of the connecting portion J does not match in the step S505 as in the connection between the panel P1 and the panel P2, the connecting portion J is connected using a crank-shaped pipe like the pipe h1 in the step S511. And exit.

Also, if the position of the connecting portion J is not in the same direction as in the connection between the panel P3 and the panel P4 in step S505 and the connection between the panel P5 and the panel P6, is it possible to connect with an L-shaped pipe in step S507? If the connection is possible if the L-shaped pipe h5 is used as in the connection between the panel P5 and the panel P6, the panel is connected using the L-shaped pipe and the process ends.
Further, if the connection with the L-shaped pipe is not possible as in the connection between the panel P3 and the panel P4 in step S507, the connection portion J is connected using the substantially U-shaped pipe h3 in step S515, and the process ends.

  FIG. 11 shows the connection state after the panel connection and piping shown in FIG. 12 are determined. Connection portions J corresponding to each of the panel laying regions M1 to M8 are arranged, and the two panel laying regions and the heat supply device 201 are connected by a pipe h group having a shape suitable for connection between the connection portions J. You can see how they are.

As described above, after the panel arrangement and piping are performed in step S113, the arrangement and piping are adjusted with reference to the information on the used parts and the information on each room stored in the plan master file 9.
In step S115, the hot water feeder 201 is selected, and a flow system diagram is created. The panel connection unit 55 reads the channel resistance values R1 to R8 corresponding to the panels P1 to P8 from the storage unit 31, and the entire panel when the panels are connected (a group when the panels are connected is referred to as “system”). ) Is obtained. This flow path resistance value needs to fall within a predetermined reference flow path resistance range value. The channel resistance value for each system is compared with the reference channel resistance value, and if the channel resistance value exceeds the range of the reference channel resistance value, the connection between the panels is changed.

When the panel connection unit 51 calculates the panel connection so that the channel resistance value of each system is within the range of the reference channel resistance value, the system creation unit 57 creates a channel system diagram.
FIG. 13 is a flow path system diagram created by the system creation unit 57 in Embodiment 1 of the present invention. In the example shown in FIG. 11 and FIG. 12, the series connection of the panels P1 and P2 is the system 1 and the combined flow path resistance is R12, the parallel connection of the panels P3 and P4 is the system 2 and the combined flow path resistance is R34, The series connection of panels P5 and P6 is system 3, and the combined flow resistance is R56, and the series connection of panels P7 and P8 is system 4, and the combined flow resistance is R78. In FIG. 13, the system 1 to which the panels P1 and P2 belong is connected to the hot water feeder 201 via the thermal valve 1, and the system 2 to which the panels P3 and P4 belong is connected to the hot water feeder 201 via the thermal valve 2. The system 3 to which the panels P5 and P6 belong is connected to the hot water supply 201 through the thermal valve 3, and the system 4 to which the panels P7 and P8 belong is connected to the hot water supply 201 through the thermal valve 4. Is shown.
If the combined flow path resistance value for each system exceeds the reference flow path resistance, the piping process in step S113 is repeated.

Next, in step S117, the flow rate calculation unit 59 obtains flow rates Q1, Q3, Q5, and Q7 from the heat supply device 201 for each of the systems 1, 2, 3, and 4.
In step S119, the flow rate determination unit 61 determines whether or not each flow rate exceeds the rated flow rate value of the hot water supply device 201. If the flow rate exceeds the rated flow rate value, steps S113 to S117 are repeated. The process ends when the flow rate is appropriate in all systems.
Further, if it is determined that the rated flow rate value is exceeded, the hot water supply device 201 having a different rated flow value may be selected again.

  When the panel laying and the automatic design of piping are completed as described above, the design content is displayed on the monitor 4 or entered in the cost estimate 15. The design contents used for the monitor 4 and the estimate sheet 15 include, for example, the types of panels to be laid for each panel laying planned room, the types of pipes to be used for each system, flow path resistance values and flow rates, unit prices of parts to be used, These are the cost for each room where the panel is scheduled to be installed, the overall cost, the layout of the panels, and the piping diagram.

As described above, according to the floor cooling and heating design support system 1 according to the first embodiment, the location where the actual dimension is known is specified and the location of the location is specified for the image floor plan that includes the original floor plan 15. By inputting actual dimensions, the scales of the original floor plan 15 and the image floor plan 115 can be obtained. If the scale is known, if a panel layout planned room or an area where panel layout is impossible on the original floor plan 15 or the image floor plan 115 is designated with the mouse 6 or the like on the image floor plan, the actual area of the designated area will be displayed. Dimensions can be obtained, and floor plans with accurate dimensions and positional relationships can be obtained.
In addition, if the floor plan is accurate, the panels and pipes can be accurately arranged.
In addition, since grid-like grid lines are displayed on the image floor plan, it is easy to confirm the scale of the image floor plan.

In addition, information on the parts to be used and files to be referred to at the time of design are given in advance. If information on the room where the panel is to be installed is entered, the selection and placement of the panel according to the room where the panel is scheduled to be installed, and piping are automatically performed. Calculated by
In general, when laying floor heating and cooling, it is necessary to design by changing a number of parameters such as room dimensions and heat capacity, panel and pipe size and performance, and combined channel resistance and flow rate when multiple panels and pipes are connected. There is. However, according to the first embodiment, the user only has to input known information such as room information, and performs complicated and complicated calculations, or changes parameters based on experience and intuition. Therefore, the design load can be reduced and the design accuracy can be increased.

  In addition, the panel connection and piping are calculated in consideration of the flow resistance value and the flow rate value for each system with the panel connected, so the accuracy of panel and pipe selection and placement can be improved. It is possible to prevent the connection of the panel and the pipe from being redone when arranging.

  In addition, it is possible to select whether or not to arrange the panel in consideration of the joist direction. When the case of considering the joist direction is selected, the panel arrangement is performed in consideration of the joist direction. Thereby, when installing a panel actually, it is not necessary to consider a joist anew, and it becomes easy to nail to a joist avoiding piping in a panel at the time of construction.

  Also, when calculating the piping of the panel, the connection portion J is selected in consideration of the positional relationship between the two panels, and the pipe to be used is selected by referring to the relationship between the connection portions. The panel can be installed with a good distribution balance between the amount of antifreeze supplied to the panel and the heating capacity, and thus with high heating efficiency.

  In addition, after creating the mesh 121 with a predetermined interval in the panel laying planned area, after forming the block 123 surrounded by the mesh 121, the fault area that becomes the fault in the block is specified, Since the block excluding the area is calculated as the panel laying area, an appropriate panel laying area can be obtained.

Embodiment 2. FIG.
In the second embodiment according to the present invention, a function is further added to the operation in the first embodiment.

  In the first embodiment, the original floor plan 15a on the first floor is read to acquire the image floor plan 115a, and the scale is acquired from the dimensions of known locations in the image floor plan 115a. If this operation is also performed on the original floor plan 15b on the second floor shown in FIG. 2B, the scale of the second floor can be obtained by performing the same operation as that on the original floor plan 15a.

  The user obtains the floor plan image of the first floor and the second floor, and selects the points and ranges that coincide in the vertical direction on the first floor and the second floor, for example, the four corners of the building, the area of the staircase, and the pillar. Select on floor plan and floor plan image floor plan. Then, the control unit 30 matches the positional relationship between the first floor and the second floor with reference to the image data of the floor plan and the scale. Specifically, the position information on the image data of the image floor plans 115a and 115b on the first floor is corrected with reference to a point that coincides in the vertical direction.

  As described above, even when the image floor plan is acquired for a plurality of floors, the scale of each image floor plan can be acquired. Therefore, the floor cooling and heating design support system 1 can perform the image floor plan of each floor in a state where the scales match.
