[Equest-users] Questions Regarding SS-N and SS-O Reprts and Unoccupied Heating and Hummidty Requirements

[James Hess]

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.

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.

Can you please let us know what you find out?  The community at large might be interested in knowing.

Here are some "Thermal Zone" variables that might be useful for diagnosing the operation.

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?
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?

Peculiar questions, I know.
