[Equest-users] zones/hvac system assignments

In the attached you will see a simple building which is (supposed to be)
served by just two HVAC systems, each serving one-half the building.  In DD
wizard, I defined only two systems accordingly, however you will see how the
four zones on one half of the building each have separate systems
(referencing model tree on left), whereas the red highlighted zone is on the
same system as the four other zones on that half of the building as
intended.  How do I get the four zones on the other half of the building
assigned to the same system in DD edit (and then delete the other three HVAC
systems)?

Hi Kent,

 

Another approach could be to have 2 instances of eQuest open - one looking
at your wizard level zonal names/inputs for reference only, and the other
open to a separate "working" detailed model (these being 2 separate project
files).  Multiple monitors makes this sort of exercise notably simpler.

 

For the detailed model, I'd suggest navigating to the airside HVAC tab, and
from here you can double click on systems and zones to rename as you wish
to.  Note that highlighting a zone on the left will highlight the
corresponding zone in the 2D zone window.  Between these visuals, you can
almost certainly figure out which is which in 9 out of 10 cases.  If you
have lots of shells, multiple floors, or other contributing factors making
this tricky, you can navigate over to the space tab to review where spaces
are from the 3D view as needed.

 

Lots of ways to skin this cat.  For future reference, I too only very rarely
invest time trying to name stuff in the wizards, as very little carries
forward into detailed mode (note some prefix/suffix options that are of use
for shells and systems however).  Naming of stuff basically happens in
detailed edits, to the extent needed.

 

Hope this helps too!

Hi Kent:

 

Unfortunately, the wonderful names you established in the Wizard do not
translate into the Detailed Edit mode. You will need to rename them in the
Detailed edit Mode (always save a copy of your Wizard Mode in case you need
to recreate). To figure out which zone and HVAC systems are which in Detail,
go back to Wizard and take a screen shot (or sketch) the shapes of your
zones (with names). Go to the Detail Edit mode and gp to a zone and ompare
the shape to your Wizard mode. Now you can retype the name into the Detail
mode.

 

Just the way it is. Good luck.

I have an existing building that has been renovated and expanded.  The
existing area and new addition area are basically an open area with only a
service counter separating the two areas (new pharmacy).  The existing HVAC
system is left in place to serve the existing floor area, and the addition
is getting a new system.  There are two restrooms; one served by the
existing HVAC, and the other served by the new HVAC.  An elec/data room has
its own little mini-split, and one other room has a unit heater.  So this
brings a total of four different HVAC systems.  I defined these systems in
the DD wizard, and wasn't able to utilize the zone assignments screen after
drawing new zones to coincide with these systems and different occupancy
types, so I intended to finish assigning zones in detailed edit.  I did not
separate existing floor area vs new area since it is open area.  After
defining the HVAC four systems in the DD wizard, I can't seem to find any
trace of them in detailed edit.  Where do I best define these six thermal
zones and HVAC systems?
