Re: [EnergyPlus_Support] Re: Modeling Heating w/ "Chilled" Beams





Appologies...I see it is treated as a terminal unit, not a zone equipment. I would also switch to a fancoil for the heating scenario and apply a recirculation factor to match the induction air of the real unit.

I don't recall being able to put a zone on more than one airloop. You can do more than one system, for example DOAS and an FCU, but I don't know about two different air terminals.

However, the designers have opted to remove the baseboard radiant and go with dual mode "chilled beams" that will also do the zone heating.
