Return fan Flow Illustration 5.16 Drives Used in a Variable Air Volume System For more information, consult the Danfoss supplier for the Variable Air Volume: Improving VAV Ventilation Systems application note. 5.3.4.2 Constant Air Volume Constant air volume (CAV) systems are central ventilation systems used to supply large common zones with the minimum amounts of fresh tempered air.

Decreasing the airflow, reduces the energy used to heat or cool the fresh air, resulting in further savings. Several features of the Danfoss HVAC dedicated drive can be used to improve the performance of a CAV system. One concern of controlling a ventilation system is poor air quality. The programmable minimum frequency can be set to maintain a minimum amount of supply air regardless of the feedback or reference signal.
