Swimming Pool Dehumidification Calculator
Calculate pool evaporation rate, moisture removal, latent load, and recommended dehumidifier capacity for preliminary engineering assessment.
For preliminary engineering guidance only. Final system selection must consider ventilation, outdoor air latent load, condensation control, and manufacturer data.
INPUTS
Enter pool and indoor conditions
Pool Length (m)
Pool Width (m)
Room Air Temperature (°C)
Room Relative Humidity (%)
Water Temperature (°C)
Safety Factor (%)
recommended : 5% - 20%
Pool Type / Activity Level
higher activity = higher evaporation
Occupancy Mode
unoccupied = reduced evaporation
Enter the pool details and click Calculate.

Notes
-
Results are based on steady-state evaporation from the pool water surface only.
-
Actual load may increase due to ventilation, outdoor air, wet deck evaporation, and infiltrations.
-
Typical indoor pool RH target: 50% - 60% for comfort and building protection
-
This tool provides preliminary sizing only. Final system design must be performed by a qualified HVAC professional.
