The following example, using an of f ice building, will calculate
the costs bet ween AC and EC technology. During the day the
employees need fresh air so all fans run at 10 0%. During the
night nobody is in the of f ice so the fans can be slowed down to
50%. To reduce AC fans to 50% you need a frequency inver ter
like the Fcontrol from Ziehl- Abegg. In our example we com pare 10 FE2owlet- AC fans (FN 071) with 10 FE2owlet- ECblue
(FN 071).
