Ventilator and control method of ventilator

摘要

VentilatorBy 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 amount of air from the indicated operating wind quantity and.The voltage value calculating section (33) calculates the command value by adjusting the acquired voltage value based on the bias value.
