<p> The DOAS will be the system you need to add the ERV to. I
normally do this in the DD wizard and that was what the previous
instructions were for. Take a copy and go back to the DD wizard,
it will warn you that you are going to lose information you have
added in the detailed edit and you will. Go back anyway, you have
a copy to use later in the detailed edit. Follow my instructions
to turn on the ERV, you may or may not want to set it up as stand
alone, that will depend on how you are modelling your system.
Once you have the enthalpy wheel turned on you should be able to
select your custom curve and replace the default one Equest is
using. Run your simulation and then compare your run in the
wizard to your detailed edit file. Before you start adjusting the
detailed edit file make another copy. You should be able to look
at your summary sheets on the 2 runs and determine which settings
are different and adjust the detailed edit so it is similar the
the output of the DD wizard. I have never done it this way but I
think once you create a template in the DD wizard to refer to you
should be able to spot the differences in the detailed edit and
make changes to get you back on track. You might also steal
portions of the INP file from the DD wizard and place them in the
detailed edit. If you don't have too much information in the
detailed edit added you could just restart with the DD wizard.
Make sure you use copies so you don't lose what you have. Also
note a DOAS can be tricky in Equest. Make sure your difficulties
are not due to how you have modelled it. Good luck.<br>
Just as a general observation, don't get into the detailed
edit too quickly. The DD wizard should handle 95% of all
situations, if you can't get it to run in the DD wizard going into
the detailed edit will just magnify your problems. I stay here
and continually go back into the DD wizard to tune my model. If
you don't add anything in the detailed edit you have nothing to
lose. To do this go to the project & site tab, go to the top
and select mode, select wizard data edit. Using this method I
incrementally build my model, making sure each addition runs. It
makes it easier to find errors because you add to the model in
sections. <font size="3" color="black" face="Times New Roman"><span
style="font-size: 12pt;">If it doesn't run you have a smaller
number of variables to work on to get it running. I just use
the detailed edit to modify control points etc to fine tune
everything but that can also be done by going back into the
wizard.<br>

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.<o:p></o:p></span></font></p>

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.<br>

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?</span></font><o:p></o:p></p>

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.<br>
<br>
Good luck!<br>

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.</span></font><o:p></o:p></p>
