The cooling load is calculated in the exact same way. The enthalpy difference over the cooling coil from the psych chart is about 10 or 11 btu/lbm, we will assume 10. Given the same volumetric flowrate, this will require a cooling load twice that of the heating. The calculated load on the cooling coil is about 1400 Kbtu/hr.
