Sensible Heat Ratio
Imagine conditioned supply air as a sponge. As it enters a room, it absorbs heat
and moisture. The amount of heat and moisture absorbed depends on the
temperature and humidity of the supply air. This “sponge,” the supply air, must
be cool enough to pick up the room's excess sensible heat gain and dry enough
to pick up the room's excess latent heat (i.e., moisture.)
Therefore, the excess sensible and latent heat in the room determine the
required dry-bulb and wet-bulb temperatures of that supply air.
