Based on ASHRAE Application CH. 4 (places of assembly) Natatoriums
* Evaporation rate which sould be removed can be estimated from the next equation
Wp = (4 / 100000) A( Pw – Pa)Fa
Where,
Wp = evaporation of water, Kg/S.
A = area of pool surface.
Pw = saturation pressure taken at surface water temperature.
Pa = saturation pressure at room air dew point
Fa = activity factor (Table 2 page 4.6)
* Surface water temperature can be determined from next equation:
Ts = Ti - {(K / R) x (Ti - To)}
Where,
Ts = Surface temperature.
Ti = Indoor temperature.
K = 0.68 constant of vertical surface.
R = R value of structural panel.
To = Outdoor temperature.
* For Design condition use (Table 1 page 4.6)
* You have to add all indoor loads as usual.
wish it could help & if there is more information let me know
Calculate de-himidification :
1. Must calculate total heat load for room swimming pool (included koefisien heat material floor, wall, roof & equipment & tools at room swimming pool.
2. Temperature & Humidity needs looking at Psycometric Chart
3. Selection Air Conditioning with corresponding heat load calculation.
4. Selection Electric Heater or Dehumidifier with corresponding at Psycometric Chart.
