Vav hoods reduce the total quantity fo supply
and exhaust air to a space when not needed, threrby reducing total operating coasts.
The addition of the Vav fume hood vontrol system significantly
increases the hood's ability to protect against exposure to chemical vapors or other contaminants.
Many Vav hoods are also equipped with visual
and audible alarms and gauged to notify the laboratory worker of hood malfunction or insufficient face velocity.
Variable air volume(Vav) hoods differ from constant air volume(CAV)
hoods because of their ability to vary air volume exhausted through the hood depending on the hood sash position.
A Vav hood maintains a constant face velocity regardless of sash position.
To ensure accurate control of the average face vellocity, Vav hoods incorporate a closed loop control system.
