The airflow set point may be user defined, or could be
specified by the project design engineer. Most typically, an air
change per hour (ACH) recommendation would be provided. In
2020, the CDC and ASHRAE recommended the utilisation of a
portable HEPA filtered unit for the safe-reopening of schools to
be applied at a 2ACH airflow set point. Airflows corresponding
to different ACH and Area (m²) requirements based on a 2.7m
ceiling height can be seen below:

The calculation equation for the above table utilises the
following equation:
Airflow (l/s) = Area x ceiling height x ACH X (1/3.6)
Where m² is the area the zone, the ceiling height is the floor
to ceiling measurement of the zone in meters, and ACH is the
specified number of air changes.
NoTe:
If required, the airflow could be further validated with a
flow hood assembly.
