Ventilator and control method of ventilator

摘要

Ventilation deviceBy referring to the relationship between the pressure drop in the flow path which is set beforehand in the ventilator and the flow in which the air flows, and the voltage applied to the motor.The voltage value corresponding to the amount of operating air instructed to the ventilator and the pressure loss in the environment where the ventilator was installed was obtained.A voltage value calculating section (33) for calculating the command value of voltage andA bias value indicator (38) indicating a bias value which is an adjustment amount of the voltage for adjusting the wind quantity from the designated operating wind quantity.The bias value indicator (38) can designate a bias value for each of the plurality of operating air volumes.The voltage value calculating section (33) calculates the command value for each of the plurality of operating air volumes by adjusting the voltage value obtained for each of the plurality of operating air volumes based on the bias value.
