Title:
VENTILATION DEVICE AND CONTROL METHOD FOR VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/019730
Kind Code:
A1
Abstract:
This ventilation device is provided with: a voltage value calculating unit (33) that acquires voltage values corresponding to an operating air volume indicated to the ventilation device and a pressure loss in the environment where the ventilation device is installed, to calculate a voltage command value by referring to a relationship between the operating air volume previously set in the ventilation device, the pressure loss in a flow path through which an airflow flows, and a voltage applied to a motor; and a bias value indicating unit (38) that indicates a bias value which is an adjustment amount of the voltage for air volume adjustment from the indicated operating air volume. The bias value indicating unit (38) can indicate a bias value for each of a plurality of operating air volumes. The voltage value calculating unit (33) calculates a command value for each of the plurality of operating air volumes by adjusting, on the basis of the bias value, the voltage values acquired for each of the plurality of operating air volumes.
