Page 51: Appendix C: Airflow Management
Irflow anaGement The Livezi Connect airflow management system modulates the speed of the indoor fan based on the condition of the VAV system as a whole. The position of the VAV damper to each load segment is monitored and at any given time the status of the VAV system can be expressed as a nominal system airflow requirement in litres per second. -
Page 52: Airflow Profile
C.1 Airflow Profile The airflow profile represents the nominal maximum airflow for each individual load segment when the VAV damper is fully open. By adjusting the airflow profile setting for each segment, the system’s airflow management algorithm may be fine tuned to compensate for variations in room and duct size to optimise the airflow. -
