Preface
As a leading HVAC manufacturer, we deem it our responsibility to serve the
building industry by regularly disseminating information that promotes the
effective application of building comfort systems. For that reason, we regularly
publish educational materials, such as this one, to share information gathered
from laboratory research, testing programs, and practical experience.
This guide discusses HVAC systems that use:
• a dedicated outdoor air unit to treat all of the outdoor air brought into the
building for ventilation, and …
• zone-mounted terminal units to treat the indoor air.
Treating the outdoor air separately from recirculated return air makes it easy to
verify sufficient ventilation airflow and enables enforcement of a maximum
humidity limit in occupied zones.

outdoor air systems (DOAS), refer to the
