Both sensible (qs, v) and latent (q;, v) rates of heat gain result from the incoming air, which may be estimated from qs,v = maCp (to - ti) (6.15)
where ma = air mass flow rate (kg/s). cp = specific heat of air (J/kg-K).
(to - t;) = temperature difference between incoming and room air (°C). (wo - w;) = humidity ratio difference between incoming and room air (kg/kg). ifg = enthalpy of evaporation (J/kg-K).
