<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Sure, pools have been "modeled"
in DOE-2.2/eQuest. But:</span></font> <font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">The evaporation from the pool depends on
the temperature and moisture of air in the pool room which will depend on the
operation and setpoints of any HVAC alternatives. But in DOE-2, no feedback
exists. </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Furthermore, many of the interesting
options for dehumidification involve system configurations, and perhaps
controls, that are not represented by the program. (Wrap-around heat pipes,
etc., check the descriptions in the catalogs)</span></font> <font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">For heat recovery in
Vermont winters, be sure to turn
FROST-CONTROL on in the HR settings. And hope the program doesn't hang. </span></font></p>

<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">I thought someone, in
Canada perhaps, had a
single-purpose indoor pool program. Or there's TRNSYS.</span></font> <font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"></span></font></p>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Has anyone modeled a pool in eQuest? I am modeling a space that
contains a 24 X 44 foot pool. I'm estimating 55 lbs/hr of evaporation per
sf of surface area (for any period of time when the pool is uncoverd). At
a minimum I need to model space dehumidification and the energy needed to heat
the pool and replacement water. I checked the help files and am using a
reheat fan system, as suggested. </span></font></p>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I can simply input a latent load into the space to simmulate the
humidity, and manually calculate and input an energy load for pool heat, but
I'd like to do better. </span></font></p>
