Abstract

A cable route setting method according to the present disclosure includes: defining unit areas in a floor where a cable is to be wired; and specifying a cable route of the cable passing through each of the unit areas to any of a route between a left side and a right side, a route between the left side and an upper side, a route between the upper side and the right side, a route between the left side and a lower side, a route between the lower side and the right side, a route between the upper side and the lower side, a route between the left side and a center, a route between the right side and the center, a route between the upper side and the center, and a route between the lower side and the center.

Claims12

Dependent claims

A cable wiring method, comprising:

setting unit areas in a floor where cable is to be wired;
setting both end points for the cable to be laid among the unit areas of the floor where the cable is to be wired;
setting a bottom surface of each of the unit areas as a bottom surface of a rectangular parallelepiped;
calculating a total sum of cable cross-sectional areas of cables in each of the unit areas included in a route from one of the end points to another end point not passing through a same unit area twice or more, from a cable wiring state management database;
calculating an apparent cross-sectional area from the calculated total sum of the cable cross-sectional areas;
calculating a height of the rectangular parallelepiped by dividing the apparent cross-sectional area by average of long side and short side of the set bottom surface of the rectangular parallelepiped;
performing computational fluid dynamics (CFD) analysis by approximating cables passing through each of the unit areas to rectangular parallelepiped;
and
in response to performing the CFD analysis, estimating an air conditioning efficiency in the floor where the cable is to be wired.
