[Equest-users] eQuest Activating the Packaged Desiccant Option

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.
