Abstract
A humidity control and ventilation device includes: a determiner determining that another ventilation device has turned on, if at least one of an increasing variation in the rotation speed of the air supply fan and an increasing variation in the rotation speed of the exhaust fan exceeds a corresponding one of predetermined values while the air supply fan and the exhaust fan are under the constant airflow rate control; and an air-flow-rate controller decreasing one of the rotation speed of the air supply fan or the rotation speed of the exhaust fan if the determiner determines that the ventilation device is on, such that a total air supply rate and a total air exhaust rate in the ventilation target space are balanced with each other.
