2.0 PRINCIPLE OF OPERATION
Enthalpic cores work most efficiently when the two airstreams are balanced. The cores are
stacked on their respective bases and the gaps between the core stacks are sealed. Vertical
sheet metal panels are installed to form plenums.
Plenums are either 2 Core or half Core wide. Every Core Array has a pair of half Core wide
plenums on each end and all other plenums are 2 Core wide.
All plenums extend full height, from the floor of the Core Array to the ceiling panels. The
exterior surface of each plenum has sheet metal panels that cover half the frontal surface of
the plenum. These panels provide rigidity to the structure and provide a means of access to
perform annual maintenance of the cores.
Every adjoining plenum has an opposite-direction airflow. In other words, if a plenum is used for
entering air, the adjacent two plenums are used for leaving air. The installer must select which
plenums are to be used for entering air or leaving air.
The two frontal elevations of the Core Array are mirror images of each other. This means that
for every opening on one side of the Core Array, the opening straight through the Core Array on
the opposite side is in the same position. See the dimension drawing for reference on page 5
and Airflow Arrangements Figures on page 13.
Enthalpic cores work by forcing airflows to follow paths at right angles. This means that air that
is entering a plenum is shifted sideways into an adjacent plenum on the downstream side.
