you please describe your problem more specifically? What do you mean "choose the
DX Coils ground loop as my heat source"? Do you mean selecting the source
for heat pump in the wizard? A reminder is, eQUEST/DOE-2.2 does not
automatically size GHX and the default may be only good for light commercial
building. The default GHX may be too small for large building, which will result
in unrealistic high/low temperature and crash of the
program.</FONT></SPAN></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Hey everyone. Thank you for
the help so far. My current question is regarding the Heating via DX
coils with a ground loop. I have run every eQuest model successfully
with other systems (even the other DX coil options), but every time the ground
loop causes my eQuest model to crash. Literally, the program shuts down
each time I choose the DX Coils ground loop as my heat source and run the
building simulation. I would really like to see what the loads look like
for this system. Any thoughts??<o:p></o:p></SPAN></FONT></P>
