HAP AnalysisMethodology
Proper U-value calculation of surfaces
Lighting Load: 1.0 W/sq.ft.
Occupancy ~ 10 people
Evaporation load of pool (2003 ASHRAE HVAC Applications)
wp = 0.1A(pw - pa)Fa = 2.499 lb/h
Btuh = wp * 45Btu/lb = 112.5 Btuh (latent load)
Where:
pa = saturation pressure at room air dew point
pw = saturation vapor pressure taken at surface water temperature
Fa = 0.65, Condominium Pool Water Temperature = 80 F
Dry Bulb Air Temperature = 78 F % Relative Humidity = 55
