Pressure drop BEP
Air side pressure drop ENY–P3/P4
NOTE: these are the voltage
values for initial calibration
and must be correct in relation
to the actual flow rate
measurements carried out
during commissioning of the
system.
• Design imbalance between the supply and return air flow rate.
In this case, the supply/return ratio is 80% due to the presence of extractors in the bathrooms
and the desire to ensure overpressure in the space in relation to outside.

The Flow Rate/Available Static Pressure diagrams allow you to identify the calibration control voltage
for the two circuits and estimate the power absorbed by the machine with the resistance disabled.
• the design static pressure of the supply and return air circuits of the machine with the addition
of the pressure drops due to the accessories.
