Psychrometric Enthalpy Multi-Zone Sizer
Evaluate combined sensible plus latent total heat load (\(Q_T\)) using psychrometric enthalpy differences (\(\Delta h\)).
Total Enthalpy Heat Equation:
\( Q_T = 4.5 \times \text{CFM} \times \Delta h \)
Where \(\Delta h = h_{\text{return}} - h_{\text{supply}}\) is the total enthalpy change in BTU per pound of dry air.
