We are trying to model an earth air heat exchanger (EAHX) applied to a
small office building in eQuest. The ventilation system schematic is
below.

Q: 745 cfm (continuous air flow) A: 1668 sf (building gross
area)
V: 15012 cf (building gross volume) E: 3/hr (average air changes)
The EAHX has been modeled for a year span with both a spreadsheet and
GAEA. I have searched the bldg-sim listserv archives on modeling EAHXs
in eQuest and read the posts I found. One post from Demba Ndiaye to
Neeraj Kapoor (Mon Jun 23 06:17:09 PDT 2008) stated; "I recently modeled
a ground-to-air heat exchanger using GAEA. You can download a free trial
version at WWW: http://nesa1.uni-siegen.de/. You can import back the
results into eQuest."
My question is: How do I import the EAHX simulation results into eQuest?
We have a working knowledge of eQuest and can comfortably run basic
scenarios, but are not experienced users.
Thanks!
