Example
The lower limit for the airfl ow when the unit is operating in the airfl ow regulation mode.
Recommended range for the design working point.
Permissible operating range when the fan is controlled to operate at a lower speed. If pressure
regulation is used, the airfl ow can be regulated to zero, however this presupposes a certain static
pressure drop in the ducting (approx. 50 Pa).
Permissible operating range in accordance with regulation 1253/2014
Working point with the highest air fl ow shall be found within the permissible area. In case of
unbalanced air fl ows; mean working point, supply extract shall be used.
Working points with less air fl ow is allowed to be found outside the permissible range e.g. in case of
variable air fl ow.
Max. limit, Ecodesign 2018.
Outer limit - largest permissible air fl ow at maximum speed.
Remaining outer limits.
Recommended average working point.
