10.0pt;font-family:Arial;color:navy'>James, thanks for the thought about the
fan curve. That might do it. However, I think what I am going to do is split my
Natatorium in 2 zones with a large air wall between the zones. One zone will
handle the outside air HAVC system with OSA requirements, and the other zone
will have no OSA and all of the pool evaporation load. This will solve my
different fan power problem and will represent my proposed system better.<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'>Your system looks like a heat pump
horseshoe where you use the hot gas to dehumidify and then what ever is left
over heats the pool? I think I have modeled something like this before with a
DX coil and a downstream hot water coil attached to an electric boiler that has
a efficiency much greater than 1, in other words, free, since it represents the
hot gas bypass. You have to make sure the DX coil and boiler sizes match the horseshoe
equipment capabilities. As for adding the pool load, the only thing I can think
to do is put a meter on the boiler and subtract whatever amount you are using
for dehumidification from the maximum amount the hot gas can produce and say
that is how much is available to heat your pool. Maybe something like that?<o:p></o:p></span></font></p>

exactly sure what you are trying to model either. But, I think the only
way (I can think of) to do what you are mentioning (or close to) is to create a
custom fan power curve that provides the fan power values that you expect at
the occupied and unoccupied (dehumidifier) airflows. I would then program
a minimum airflow schedule that set the minimum airflow at one value during the
occupied hours and then switched to a value equal to the dehumidifier airflow
during unoccupied periods.<o:p></o:p></span></font></p>

will completely condition both temperature and humidity for the indoor pool
environment. This equipment contains a refrigerant to water heat
exchanger to preheat the pool water using condenser heat rejection. See
the diagrams on page 10 (PDF 14) in the above referenced PDF. This is a
good match because the majority of the pool heat loss is due to
evaporation. This unit manages the pool room humidity using the
refrigeration cycle while recycling condenser heat rejection back into the
pool. Pretty cool. I don’t think eQuest can model this heat
recovery however, or at least I don’t know how. We will probably
end up with some kind of side exceptional calc based on heat recovery data
provided by the mfg (PoolPAK). The idea is that the heat recovery will
offset the gas usage of the conventional pool heating boiler, used in the
Baseline (and Proposed as supplemental heater).<o:p></o:p></span></font></p>

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>

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>

interesting to model. We are working on a project right now with one. One
challenge we have is how/where to get the heat recovery data from the equipment
vendors that sell the systems that can provide condenser heat rejection for use
in heating the pool. I’m sure we will figure that out at some
point.<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>
