RE: [EnergyPlus_Support] Variable Fan - fans in series





Dear Jean,

 

Why are you not just using a VAV fan with “Fan power minimum flow fraction” set for 30%?

Subject: [EnergyPlus_Support] Variable Fan - fans in series

 

 

Hallo All,
I need to model that the frequency converters reduce fan volume to 30% during off hours. I'm thinking of building 2 fans in series, where the one fan can only manage 30% of the other fan's volume capacity as it's maximum volume flow rate. Then I can simply switch between them using schedules.
What do you think?
