1. A ventilation system comprising:
- a plurality of ventilation devices including at least one specific ventilation device and a determination ventilation device that each include an air blowing fan;
ducts to which the ventilation devices are connected;
a fan controller configured to control a rotational speed of the air blowing fan of each of the ventilation devices;
a power detector configured to detect a fluctuation in power consumed by the air blowing fan of each of the ventilation devices; and
a connection determinator configured to determine that the determination ventilation device and the specific ventilation device are connected to an identical one of the ducts in a situation where when the fan controller drives the air blowing fan of the specific ventilation device connected to a specific duct, and changes the rotational speed of the air blowing fan of the determination ventilation device, the power detector detects a fluctuation in the power consumed by the air blowing fan of the specific ventilation device, and determine that the determination ventilation device and the specific ventilation device are connected to different ones of the ducts in a situation where when the fan controller drives the air blowing fan of the specific ventilation device connected to a specific duct, and changes the rotational speed of the air blowing fan of the determination ventilation device, the power detector does not detect a fluctuation in the power consumed by the air blowing fan of the specific ventilation device.

Abstract
A ventilation system includes a connection determinator configured to determine that N-th, second, and sixth humidity controlling ventilation devices are connected to an identical second duct bank in a situation where when fans of the second and sixth humidity controlling ventilation devices are driven, and the rotational speed of a fan of the N-th humidity controlling ventilation device is changed, a power detector detects fluctuations in the power consumed by the fan of each of the second and sixth humidity controlling ventilation devices.
