Swimming Pool Dehumidifcation
(OP)
Can anyone help me in determining how much cooling would be required in dehumidifcation a pool room. I understand the ASHRAE formula determining the evaporation rate of a swmming pool. This give you a water quantity in lb/hr that is evaporated into the air. Therefore, do I mulitply this amount by the latent heat of vaporization 1,050 Btu/lb of water, to determine the latent cooling load required on the cooling coil.

Reprints should still be available from ASHRAE.

I figured this is a fundamental question HVAC engineers should be able to understand, without a mfr's support.
RE: Swimming Pool Dehumidifcation
If we should be able to understand it without mfr's or others support why ask the question? You should already know the answer.
To directly answer your question. No, that only gets you part of the way there. You still have latent load from people and outside air.

Evaporation Rate = (0.1)xArea x (Vw-Vp)Activity Factor
Activity Factor varies from 0.5 to ~2 depending on application.
I use a spreadsheet to determine Vw and Vp at various temperatures (Vp is dependant on air temp and humidity, Vw is dependent on pool water temperature).
Once you have the spreadsheet you can vary pool air and water temperature as well as pool humidity to see the effect it has on evaporation rate.
Good luck!

He gave me a Dectron manual years back. Maybe he is retired now.
Take the "V" out of HVAC and you are left with a HAC(k) job.
