When the input device 13 is operated, the input device 13 outputs a signal corresponding to the operation content to the computer 11.

  The storage unit 14 is a storage device including a semiconductor memory or a hard disk drive. The storage unit 14 may be built in the computer 11 or may be externally attached to the computer 11. The storage unit 14 stores a design program 20 that can be read and executed by the computer 11. The design program 20 is design software that realizes BIM (Building Information Modeling) and CAD (Computer-Aided Design). BIM and CAD are realized when the computer 11 executes the design program 20.

Identify the mass collection. The computer 11 specifies the outline 67 of the aggregate and the area 69 inside the aggregate. By doing so, the computer 11 extracts a region 69 inside the outer shape 67 from the region 63 inside the closed curve 61 including the straight line portion. A region 69 inside the outer shape 67 is referred to as an interior zone 69. The outer shape 67 of the interior zone 69 has right-angled corners E1 to E6 and right-angled corners I1 to I10. The outgoing corners E1 to E6 and the incoming corners I1 to I10 are inner angles of the outer shape 67, the inner corners of the outgoing corners E1 to E6 are 270 °, and the inner angles of the incoming corners I1 to I10 are 90 °. The outgoing corners E1 to E6 are arranged in the order of the outgoing corner E1, the outgoing corner E2, the outgoing corner E3, the outgoing corner E4, the outgoing corner E5, and the outgoing corner E6 along the outer shape 67 in the counterclockwise direction.

The unit air-conditioning area data 33 may be acquired. In addition, the computer 11 may acquire the area as the unit air-conditioning area data 33 when the user inputs the area that the air conditioner is responsible for air-conditioning to the computer 11 by the input device 13.

  Next, as shown in FIG. 5, the computer 11 sets a scanning point 73 and a line segment 75 from the scanning point 73 to the outer shape 67 at an arbitrary position on the closed curve 61 including the straight line portion (hereinafter referred to as a starting point P0). To do. For example, the line segment 75 is a tangential perpendicular at the scanning point 73.

  Next, the computer 11 makes the scanning point 73 and the line segment 75 go around along the closed curve 61 including the straight line portion. At this time, the computer 11 displaces the scanning point 73 and the line segment 75 along the closed curve 61, and draws a minute region drawn by the line segment 75 along with the minute displacement of the scanning point 73 (the line segment 75 and minute line before the minute displacement). The area of the region drawn by the line segment 75 from the start point to each position on the closed curve 61 including the straight line portion is calculated by integrating the area of the region between the line segment 75 after displacement). In other words, the computer 11 integrates the function representing the length of the line segment 75 by displacing the scanning point 73 and the line segment 75 along the closed curve 61 including the straight line portion, and the closed curve including the straight line portion from the start point. The area of the region drawn by the line segment 75 up to each position on 61 is calculated. When the scanning point 73 and the line segment 75 go around, the line segment 75 draws the entire perimeter zone 71, and the integrated value at that time represents the area of the perimeter zone 71.

  After calculating the area of the region drawn by the line segment 75 from the start point to each position on the closed curve 61 including the straight line portion, the computer 11 determines that the integrated value (that is, the area of the region drawn by the line segment 75) is the unit air conditioning area. The positions P1 to Pm of the scanning points 73 that are integral multiples of the value of the data 33 are specified. Here, m is an integer, and m = 8 in the example shown in the drawing.

Here, n = m + 1, and n = 9 in the example shown in the drawing. The area of each region A1 to Am is equal to the value of the unit air-conditioning area data 33, and the area of the region An is equal to or less than the value of the unit air-conditioning area data 33.
