Verfahren und Vorrichtung zum Betrieb einer Zentralabluftanlage insbesondere für holzverarbeitende Betriebe, womit ein Mindestwert des Gesamtvolumenstromes im Abluftsammelrohr aufrechterhalten wird

摘要

The invention defines a reference value (Vref) which can be used, particularly as a reference total flow rate, to determine whether the rate of flow of the air in the exhaust-air main (AR) is at a certain minimum value. In addition, characteristic values are defined for the intake pipes (AB1...ABn) on the exhaust-air main, which can be used, particularly in the form of intake flow rates, to determine the contribution of each intake pipe to the total flow rate in the exhaust-air main when a valve (VS1...VS2) in the intake pipe is opened. The characteristic values of the open intake pipes are summed to give a total intake flow rate (V), which is compared with the reference total flow rate. If the total intake flow rate is less than the reference flow rate, additional intake pipes are opened in order to match the total intake flow rate (V) as closely as possible with the reference flow rate.
