VENTILATION SYSTEM

摘要

A ventilation system (S) is provided with a connection determination unit (5c) that drives the fans (25, 26) of a second and a sixth humidity-controlling ventilation device (10b, 10f), and when the rotational frequency of the fans (25, 26) of the N-th humidity-controlling ventilation device (10n) has been changed, if a power detection unit (5b) detects a change in the power consumption of the fans (25, 26) of the second and sixth humidity-controlling ventilation devices (10b, 10f), determines that the N-th humidity-controlling ventilation device (10n) and the second and sixth humidity-controlling ventilation devices (10b, 10f) are connected to the same second duct bank (2).
