[Equest-users] HVAC system

[Vikram Sami]

Hind,
You have to create a dummy space with a dummy zone attached to it. You
then assign it to your DOAS system. Make sure your DOAS system is the
first system defined on your inp file. You will then need to assign your
FCU system with an OA-From System (this will be your DOAS system).

Hi All,

I am trying to model a fan coil units serving each zone and a fresh air
air handling unit serving all these zones.

While looking in the archive I conclude that we can't assign 2 systems
for
one zone, and for this reason we have to create a DOAS with a dummy
zone.
But I didn't understand the concept. Is that what should be applied in
my
case?

Plz can you explain me the idea of DOAS, and how can I model my HVAC
system.

Any help will be appreciated. Thanks
