[Equest-users] eQuest Activating the Packaged Desiccant Option

[Michael Andelman]

Kathryn,

I believe if you read the documentation, the solid desiccant model is "hard
wired" - no curves are available.

The only work-around I know of is to model it as a liquid desiccant system
and enter the curves that are appropriate for the solid desiccant system.

Bruce, I am trying to enable the Packaged Desiccant option in Detailed Edit.
The system I want to model is a packaged unit to be added to a DOAS.  This
unit contains proprietary desiccant wheels and heaters. It has performance
curves. I wish to make performance curves and activate them in the Detailed
Edit mode Packaged Desiccant tab. The curves that I made show up as
selectable in the Packaged Desiccant tab, along with other curves, but I
can't get any of these curves to appear as a selected in the Packaged
Desiccant tab. I can't get any of the curves selections that show up in the
drop down menus on this tab to select, either. I also can't access the
library or create selection that shows up in the drop down menu.

 

So my question is, what do I need to do to get the Packaged Desiccant tab to
work?

I'm not quite sure what you are getting at or want to do.  Speculating I
would assume you are working with outside air and heat recovery.  If that is
the case, in the DD wizard, under the air side HVAC tab right click on your
system, select properties.  Go to outdoor air, heat recovery 1, ERV device
installed, select yes, in the pop-up select enthalpy wheel.  You can also
select stand alone in one of the tabs as well.  There are various
performance items you can specify, and I would assume Equest would then
allow you to select a performance curve as well.

I can do that, and indeed I activated the the liquid heat pump option to get
some idea what kind of dew point I was looking for. But that is not really
what I want and the solid desiccant doesn't option doesn't have curves you
can adjust (at least none that I could find). So you can't get the Packaged
Desiccant to work either? Anyone else have success?

I could not enable the packaged desiccant curves but setting the "maximum
humidity" value on the basics tab of the system enables the Desiccant
Performance Curves and you can set your add on desiccant type to Solid Vent
Air 1 and select the appropriate control mode/configuration to (hopefully)
give you the closest system.

Good luck!

Does anybody know how to activate the Packaged Desiccant option in eQuest? I
have created some curves that I think might work and they show up as part of
the possible selectable curves when I click on the Packaged Desiccant Tab
curves individually, but I can't get the Design Wizard to select this curve
or indeed, any curve from the possible list that appears. What am I missing?
Some other part of another tab that needs to be activated? If so, where? I
just assumed that this option worked and if I could make curves, I could use
it. Maybe it doesn't work? If this is true, I am going to be peeved.

 

Thanks for listening.
