(1000 × 2.01) and 1.381 V (volts), the voltage drop E2 of the second unit is (2 × 17.8 × (7.8
+7.8) × 15) / (1000 × 2.01) = 4.1
4V (volt), and the allowable voltage drop Es is E1 + E2
The voltage becomes 5.521 V (volt) of 1.381 + 4.14.

Therefore, since the voltage drop is large because 5.521> 4 volts, the thickness of the electric wire is calculated by one rank higher.

That is, a thickness of 2 mm (a sectional area of 3.14 m)
m ² ), the first voltage drop E1 is (2 × 17.8 × 7.8 × 10) / (1000 × 3.1)
4), it becomes 0.884 V (volt), and the voltage drop E2 of the second unit is (2 × 17.8 × (7.8 + 7.8) × 15).
/(1000×3.14) is 2.653V (volt), and the allowable voltage drop Es is 0.884+ in E1 + E2.
It becomes 3.537V (volt) of 2.653.

Accordingly, since 3.537 ≦ 4 volts, the voltage drop is satisfied, and thus the thickness of 2 mm is suitable.

As described above, the CPU of the terminal 3 selects (calculates) the wire diameter of each wire, and as a result, the thickness (diameter) of the wire between the indoor units A1 and A2 of Company A and the result Indoor unit A
The wire (diameter) between the wire 2 and the breaker is 2.00 m
m is controlled to be displayed on the screen of the terminal 3. In addition, the selection of a breaker, a three-phase power supply, and the like is also selected according to the above-described extension.

Therefore, a facility contractor or the like can print this screen using a printer (not shown) and use it for facility design.

Next, a second embodiment in which the application software is used via a browser without installing the application software on its own terminal 3 will be described.

In this case, first, as described above, the arrangement of the equipment and the respective wiring lengths are input on the display device of the terminal 3, and then the information is transmitted to the information control unit 1 via the Internet line 4. Then, the information control unit 1 selects the optimum wiring diameter (capacity) of the facility in the same manner as described above.
