Sensible heating
During this process, the moisture content of air remains constant, and its temperature increases as it flows over a heating coil. The heat transfer rate during this process is given by:
Qh = ma(hB−ho) = macpm(TB−To)
where cpm is the humid specific heat (≈1.0216 kJ/kg dry air), tangent direction, and ma is the mass flow rate of dry air (kg/s).

During sensible heating of moist air, enthalpy increases.
Sensible cooling:
During this process, the moisture content of air remains constant, but its temperature decreases as it flows over a cooling coil.
