🏊 ASHRAE Applications Ch 6 (Water Evaporation Lbs/hr, Heat Recovery Dehumidifier)

Indoor Pool Dehumidification Calculator

Size commercial indoor natatorium mechanical dehumidifiers (Desert Aire / Dectron / PoolPak) under ASHRAE Applications Chapter 6: calculate moisture evaporation rate (Lbs/hour based on pool water temperature [82°-86°F], room air dewpoint [50%-60% RH], and occupant activity factor), calculate required supply airflow (CFM = 4 to 6 CFM per sq ft wetted area), and HVAC profits.
