The number of pressure transducers and the measuring range can be defaulted via a
parameter.
The number of pressure transducers and the measuring range can be defaulted via a
parameter.
In ventilation systems with a pressure transducer, the supply air pressure is captured
and compared with the selected set value. The supply air fan is then switched in
line with the deviation. The extract air fan is switched according to the switching of
DISPLAY
the supply air fan (in %) + "Diff. extract fan". By entering the k factor, the captured
pressure will be converted into flow rate.
For this, the respective fan type must be selected for every fan.
Furthermore, a number for supply/or extract air fans is adjustable. The measured
volume flow for supply or extract air is multiplied accordingly by this setting. The
prerequisite for correct calculation is that the design of the supply or extract air fans is
identical and that they are actuated parallel to one another.
Please note
Fan type 1 corresponds to the formula
Fan type 2 corresponds to the formula
The formulae for calculating the flow rate can also be found on the fan type plate.
