How to calculate de-himidification requirement for the indoor swimmingpool?

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.
