7.3 System curves
A system requires different pressures at different airflows, which can be represented by a system curve.
The intersection between the system line and the fan curve, is the unit's working point. It is showing the
airflow the system is going to have. Every change in the pressure of the ventilation system, will give
rise to a new system curve.
If you choose to do the commissioning with l/s or m
3
/h, you need to know the system’s pressure in order to
choose a suitable system curve.
