[Equest-users] Modelling DOAS/MUA in eQUEST

[Mathew Higgins]

I typically follow this same methodology, but put the DOAS in the
unconditioned "plenum" space where it's actually going to be
installed. Don't know if there is a word of caution from anyone when
doing this, but that way I don't have to go through the dummy zone
process. I typically input a "self-contained" ERV on these respective
units to simulate energy recovery as well.

Hello,
 
I want to poll the group to make sure I haven’t missed a thread on the
subject. 
 
Is the only way to model a system that separates the ventilation
requirements and the space load (Heatpump, VRF, Fan coil, etc) by
creating a dummy shell with zero loads and then passing the OA from this
dummy shell to the individual zones with “OA-FROM-SYSTEM”? My specific
system this time is a GSHP with a RTU for ventilation air that is fired
by a condensing boiler.
 
>From what I understand, heat recovery is not available for these
systems either.
 
Thanks for you help,
