<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Everyone, after stumbling around a little,
I discovered that eQuest/DOE-2 does take into account the maximum relative
humidity limit during unoccupied hours and operates the zone HVAC fan energy,
cooling and heating with the OSA closed. I figured this out by running the fan
system 24/7 (it was running 24/7 anyway according to SS-C) and noticing that
the total energy consumption did not change. Humidity and temperature data then
appeared in SS-N and SS-O reports. I also found some help files that state that
0 in the MinOA schedule means closed OSA so I know there is no OSA going into
the pool area at night. So the model I had was working fine, I just couldn’t
prove it. Running the HVAC system 24/7 proves it.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>So, now I am at the point of introducing
my dehumidifier system to the pool zone. I am planning on using the pool PSZ HVAC
cooling coil to represent the dehumidifier cooling coil since the specified PSZ
HVAC does not use a cooling coil. What I would like to do, is decrease the PSZ SUPPLY-KW/FLOW
value during unoccupied hours to represent the lower dehumidifier fan rate.
Does anybody know how to do this? In other words, I want the pool zone PSZ HVAC
supply fan to run at 0.0007 kw/cfm during the day and run at 0.0003 kw/cfm
during unoccupied hours. If I can’t change SUPPLY-KW/FLOW, is there a way
to develop a schedule that DECREASES the electric load by some amount during unoccupied
hours? I have found ways to add a load, but not subtract.<o:p></o:p></span></font></p>

w:st="on"><st1:place w:st="on">Alaska</st1:place></st1:State>. I have figured
out how to model the pool's 24/7 latent load and required the pool area HVAC
system to maintain 88 F even for Night Cycle. I also gave the pool HVAC the
task of maintaining 60% max RH. The SS-C report shows the pool HVAC fan running
8747 hours out of the year, 2357 of those hours running during unoccupied
hours. This is what I expected. I looked at the SS-O and SS-N reports for my
pool area and pool HVAC and noticed that 6390 hours of temperature and relative
humidity data are showing up, not 8740 hours. In other words all the 2357
unoccupied hours are not showing up. How do I verify if my pool HVAC
system succeeded in managing to keep 88 F and below 60% RH during the
unoccupied period? I assume it can manage the temperature problem, but how well
did it manage the humidity problem? Or did it just bag the humidity problem, in
which case, do I have to run the fan system 24/7 to get it to pay attention to
the 60% max RH?</span></font><o:p></o:p></p>
