All,

Has anyone tried implementing evaporative cooling with chilled beams (induction units) in eQuest?

If I implement Indirect/Direct in the VAV System that supplies the outside air to the chilled beam zones I get a massive increase in fan energy (about 10 times).
If I just implement the Direct evap cooling, I get a 90% fan energy savings.
The results I should be getting is a slight increase in fan energy, and a cooling energy savings, but that's not happening.

If I implement it in the Induction Unit system itself, I get a NAN error in the BEPS report.

Any help would be appreciated,
