To determine the starting and final enthalpy, locate
the intersection to 70
OF
dry bulb and 20% RH and
follow the diagonal line from this intersection to scale
C and read the enthalpy (20.3 BTU's per pound of
dry air).
Since atomizing humidification does not increase
enthalpy, the final enthalpy will be the same.
However, if you follow the diagonal line from 70
O
F
dry bulb and 20% RH to its intersection with 60% RH
and then follow the vertical line from this intersection
to scale A you will now read a dry bulb temperature
of 57.2
0
F.
You will note that the dry bulb temperature will have
been reduced while the enthalpy has remained
constant. This evaporative cooling effect is what
makes the Herrmidicool invaluable in applications
where full or partial year-round cooling is required.
