<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";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></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:navy"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";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></p>

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></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">There’s no way to add a negative value to a meter. I wish we could. I made that suggestion to the eQuest developers about 5 or 6 years ago, but never heard
anything back. I agree it would be a nice option. We could add in solar PV or solar thermal estimates from other programs, for example.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Basically, this unit 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></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";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></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:navy"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";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></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Pools are 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></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">For your project, I would recommend creating an hourly report for that zone with zone temp and humidity. Then run eQuest, export hourly report, and then analyze
to see what’s going on.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">Everyone, I have an indoor pool in Alaska. 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><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">If I have to run the fan system 24/7 will that 0 value in the MinOA WD schedule keep the outside from coming on or do I need to change it to a positive number? If so, which
positive number? 999?</span><o:p></o:p></p>
