Latent Dehumidification Load Calculator
Determine latent heat gains (\(Q_L\)) and daily moisture removal capacity requirements.
Latent Heat Equation:
\( Q_L = 0.68 \times \text{CFM} \times \Delta G \)
Where \(\Delta G = G_{\text{return}} - G_{\text{supply}}\) represents moisture ratio difference in grains of water per pound of dry air (\(7,000 \text{ grains} = 1 \text{ lb water}\)).
Moisture Parameters
Typical 75°F / 50% RH = ~65 grains/lb
Typical conditioned air = ~45 grains/lb
Moisture Delta ($\Delta G$)
20 grains/lb
Latent Heat Load ($Q_L$)
16,320 BTU/hr
Dehumidification Capacity
373 Pints/Day
Moisture Removal Rate Summary
Removing 20 grains/lb from 1,200 CFM equates to 15.5 lbs of water removal per hour (373 pints/24 hrs).
