The air system is directing an air stream into the zone at some air mass flow rate. That air stream will typically have a different temperature and moisture content than the zone. The difference between the air stream's air properties and the zone's air properties is the basis for the cooling or heating sensible or latent energy transfer. It does not matter if a coil is on or off, or even present in the air stream. What matters is the difference in air temperature, or other air property, from the zone conditions.
Qtotal = Mdot * (Hin - Hzone)
Qsensible = Mdot * CpAir * (Tin - Tzone)
