[BLDG-SIM] Modeling a pool in eQuest [mistake in 1st email]

Sure, pools have been "modeled" in DOE-2.2/eQuest. But:

 

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. 

 

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)

 

For heat recovery in Vermont winters, be sure to turn FROST-CONTROL on
in the HR settings. And hope the program doesn't hang. 

 

I thought someone, in Canada perhaps, had a single-purpose indoor pool
program. Or there's TRNSYS.

Oos.  That's 55 lbs/hr total, not per sf.

Hello All,

 

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. 

 

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.

 

Thanks,
