<DIV><FONT face=Arial size=2>First, if you use the wizards, you must change
to "detailed edit" mode</FONT></DIV>
<DIV><FONT face=Arial size=2>to get access to the full interactive DOE-2 program
input (BDL) and</FONT></DIV>
<DIV><FONT face=Arial size=2>then create/delete the needed/unwanted
equipment.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Create your building with the wizard using WLHP
system,</FONT></DIV>
<DIV><FONT face=Arial size=2>- switch to detail mode</FONT></DIV>
<DIV><FONT face=Arial size=2>- In the water-side module,right-click on the root
entry of the component tree</FONT></DIV>
<DIV><FONT face=Arial size=2> (the </FONT><FONT face=Arial size=2>project:
'name' item) and create a "ground loop heat exchanger" (be ready to</FONT></DIV>
<DIV><FONT face=Arial size=2> supply complete ground well/trench design
information) attaching it to </FONT><FONT face=Arial size=2>the
WLHP</FONT></DIV>
<DIV><FONT face=Arial size=2> circulation-loop</FONT></DIV>
<DIV><FONT face=Arial size=2>- delete any <FONT face=Arial size=2>dedicated
fluid cooler pump - not the WLHP loop - mostly will not exist in</FONT>
<DIV><FONT face=Arial size=2> wizard created
projects</FONT></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2>- delete the fluid cooler (if it not to run in
parallel with the GLHX, see</FONT></DIV>
<DIV><FONT face=Arial size=2> DOE-2 manuals for details on this
option) </FONT></DIV>
<DIV><FONT face=Arial size=2>- delete any dedicated (attached) boiler pump
- not the WLHP loop - important</FONT></DIV>
<DIV><FONT face=Arial size=2> that you do this so that an
"unattached" pump does not remain after you next</FONT></DIV>
<DIV><FONT face=Arial size=2> delete the boiler.</DIV>
<DIV></FONT><FONT face=Arial size=2>- delete the boiler </FONT></DIV>
<DIV><FONT face=Arial size=2>- create BOTH heating and cooling design days (this
is required for a decent</FONT></DIV>
<DIV><FONT face=Arial size=2> GLHX simulation as the design days are
used to initialize the ground field</FONT></DIV>
<DIV><FONT face=Arial size=2> temperature history - an annual
history is needed due to long term ground</FONT></DIV>
<DIV><FONT face=Arial size=2> response); do this by right clicking
on the project: entry of the component</FONT></DIV>
<DIV><FONT face=Arial size=2> tree in the Project & Site
module</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Next you need to convert the zonal HP units to be
"extended range" units that</FONT></DIV>
<DIV><FONT face=Arial size=2>can tolerate low and high loop temperatures without
shutdown due to temperature</FONT></DIV>
<DIV><FONT face=Arial size=2>limits for compressor protection. You can do
this manually, but we have posted</FONT></DIV>
<DIV><FONT face=Arial size=2>an "import" file for eQUEST that makes most of the
changes for you.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>
<DIV><FONT face=Arial size=2>First, extract the following linked file into your
eQUEST projects directory.</FONT></DIV>
<DIV><FONT face=Arial size=2> <A
href="http://doe2.com/download/equest/GroundLoopHP_curves.zip">http://doe2.com/download/equest/GroundLoopHP_curves.zip</A></FONT></DIV></DIV>
<DIV><FONT face=Arial size=2>- file/import the extracted file, SKIP the
pre-processing step (click 'No")</FONT></DIV>
<DIV><FONT face=Arial size=2> to prevent precessing errors by that
process (otherwise you import of this</FONT></DIV>
<DIV><FONT face=Arial size=2> file may not work
correctly)</FONT></DIV>
<DIV><FONT face=Arial size=2>- save then re-open the project to force all
defaults from the import</FONT></DIV>
<DIV><FONT face=Arial size=2> process to take effect (this step is
temporarily needed prior to an eQUEST</FONT></DIV>
<DIV><FONT face=Arial size=2> update scheduled for later this
month)</FONT><BR>---<BR>Jeff Hirsch<BR>James J. Hirsch &

GSHP in eQUEST and hourly zone/coil loads</DIV>
<DIV><BR></DIV>
<DIV id=idOWAReplyText55047 dir=ltr><FONT face=Arial size=2>Dear bldg-sim
users:</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>I have two questions with regard to
eQUEST. Is there anyone can help me out?</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>(1). As I know, eQUEST has the capability
of simulating GSHP, but it has to be done in the detailed mode. I'm wondering
whether there is any documentation, or even better, example to show how to
build a GSHP simulation in eQUEST?</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>(2).</FONT> Can eQUEST report hourly
zone loads and coil loads? If so, how to do it? </DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>Thanks in advance,</DIV>
<DIV dir=ltr> </DIV>
