CORE ARRAY
Determine the airflow paths for your job. The two airstreams are the Supply Air (air from
outside) and Return Air (air from the conditioned space).
If the Supply and Return Air enter the Core Array on OPPOSITE sides, use Arrangements 1 or 3.
(See Figures 2.0.0 and 2.0.2)
If the Supply and Return Air enter the Core Array on the SAME side, use Arrangements 2 or 4.
(See Figures 2.0.1 and 2.0.3)
If the airstreams enter the Core Array low, and leave the Core Array high (or the other way
around), this airflow orientation is called “crossflow.” Use Arrangements 1 or 2.
If one airstream enters the Core Array high and leaves high, and the other enters low and leaves
low, this airflow orientation “parallel.” Use Arrangements 3 or 4. This airflow configuration
requires a performance derate.
