<p>PROBLEM TO BE SOLVED: To provide a humidity conditioning ventilation device capable of preventing fan power accompanying an operation of other ventilation devices from increasing without performing transmission.SOLUTION: A humidity conditioning ventilation device (10) includes: a determination unit (103) for determining that other ventilation devices (80 and 90) in ventilation object space (S) have come into an ON-state when at least the variation of the rotation frequency increase of an air supply fan (26) or an exhaust fan (25) exceeds a predetermined value, during air amount constant control of the air supply fan (26) and the exhaust fan (25); and an air amount control unit (101) for lowering the rotation frequency of the air supply fan (26) or the exhaust fan (25) so that the whole air supply amount and the whole exhaust amount in the ventilation object space (S) are balanced when the determination unit (103) determines an ON-state of the other ventilation devices (80 and 90).</p> |
