Latent System Capacity
The total capacity of an air conditioner is made up of the
Sensible capacity, the output of the unit used to remove heat
from the air in the area being conditioned, and the Latent
capacity, the output of the unit used to dehumidify the air
in the area being conditioned. For humid climates and
applications, the Sensible/Latent capacity split of the unit
should be considered. The Sensible capacity listed in the
specification charts on pages 52 and 53 are at standard
rating conditions of 95°F. dry bulb/75°F. wet bulb outdoors;
80°F. dry bulb/67°F. wet bulb indoors. The Latent system
capacity is 1.00 minus the Sensible capacity. (If the Sensible
capacity is listed at .74 the Latent capacity is .26. This means
that 74% of the capacity of the unit is used to remove heat
from the air and 26% is used to remove moisture from the
air at standard test conditions).

In some applications information about the Sensible/Latent
split, or ratio, at conditions other than the standard rating
conditions is needed. The charts below provide data at
various indoor conditions. To use the charts, first determine
which Zoneline model is being considered and refer to the
appropriate chart. Next, locate the indoor dry bulb
temperature under consideration across the horizontal axis
of the chart and draw a line straight up until it touches the
line representing the indoor wet bulb temperature of the
area; from this point draw a horizontal straight line to the
vertical axis. The point where the line touches the axis
represents the latent percent of the total capacity of the unit.
An example is shown for the standard indoor conditions of
80°F. dry bulb/67°F. wet bulb.
