RE: [EnergyPlus_Support] Re: Chilled beam modeling

["Simon Rees" <sjrees@xxxxxxxxx>]

Are the chilled beams in question passive or active? Passive chilled
beams are physically very similar to baseboard heaters - pipes with fins
that work by natural convection. I will need to  model a passive chilled
beam system shortly and wondered if the baseboard heater model could be
used. Would the model work in cooling mode?
Thanks, Simon

That's a good choice.
