VAV Variable Air Volume

The video tutorial explains Variable Air Volume (VAV) systems, highlighting their energy efficiency compared to Constant Air Volume (CNV) systems. It covers the components of VAV systems, including air handling units, supply and return ducts, and VAV terminals. The tutorial details how thermostats regulate temperature by controlling dampers and discusses airflow measurement using sensors. It also explores fan-assisted VAV systems and pressure control in ductwork using variable frequency drives to optimize energy use.
