Measured Outlet Temperature = 115°F
Measured Outlet %RH = 12%
Outlet Air Moisture Content (Graph 2) = 0.72 ppd/CFM
Dehumidifier Capacity = (Inlet Air Moisture Content – Outlet Air Moisture Content) * Airflow
(1.31 ppd/CFM – 0.72 ppd/CFM)*120 CFM = 70ppd
14. Compare the capacity to the approximate performance in the table below. Performance should
be within about 20% of the capacity listed below due to the estimation of airflow through the
unit:
