<p>The invention provides a fan control system that, when a plurality of fans is started up and one fan starts to rotate ahead of the others, suppresses an increase in the loads at start-up on these other fans. In this fan control system, when a first fan (21) and a second fan (22) are started up and their rotational speeds have reached target rotational speeds, which are lower than required rotational speeds, a control unit (4) controls a first motor (31) and a second motor (32) such that the rotational speeds of the first fan (21) and the second fan (22) reach the required rotational speeds.</p> |
