ギの無駄が多かつた。 Conventionally, the amount of air supplied to a paint booth was adjusted by opening and closing an air volume adjustment damper installed in an air supply duct connected to the paint booth, or by controlling the rotation speed of an air supply fan installed in the air supply duct. It was set to a predetermined amount. As the resistance of the filter, which is located downstream of the air volume adjustment damper in the supply gas direction, increases, the air supply volume decreases, so the opening of the air volume adjustment damper is periodically controlled to keep the supply air volume constant. Alternatively, the setting conditions such as the rotation speed control of the air supply fan were changed. In addition, when setting the air supply amount, it is important to avoid quality defects that occur due to a decrease in the air supply amount, that is, paint defects that occur due to paint mist scattered during painting adhering to other objects to be painted. Therefore, the air supply amount was always set to a large amount, resulting in a lot of wasted energy.

ない。 In view of this situation, methods have been proposed to continuously control the air supply amount. One of these methods is to detect the wind speed in the air supply system, and use the detection signal to control the opening of the air volume adjustment damper or the air supply fan. Attempts have been made to continuously control the rotation speed, etc. of the wind turbine, but this method has difficulty in stably detecting wind speed and has not been put to practical use.
