Packaged rooftop units provide air conditioning through direct contact between condenser coils and outdoor air, eliminating hydronic piping from the air-conditioning system. Many RTU models can also be equipped with a gas boiler to use the same air duct system for heating.
When using a VAV system, it is important to ensure that a minimum outdoor airflow is maintained, even when the total airflow is diminished in response to a reduced cooling load. This feature is sometimes overlooked, which has a negative effect on indoor air quality.
