When controlling a
Variable Air Supply unit (or VAV Unit - Variable Air Volume), two
methods are available:
- Damper Control - Unit discharge damper is adjusted using the damper
motor.
- VFD (Variable Frequency Drive) – Controller adjusts the speed of the
blower motor Discharge Damper adjustment is an older method of
controlling discharge air volume. Its main advantage is that it only
requires positional control of a small discharge damper motor. The
major disadvantage is the wasted Horsepower of the blower motor at
lower delivery rates. In either case, when the system is enabled, a
pressure sensor in the building space monitors room pressure. When a
high or low pressure reading is detected, the air supply or exhaust is
adjusted to compensate.
The air delivering capacity of axial flow fans ranges from 100 to
500,000 cubic feet per minute (3,000 to 15,000 cubic meters per
minute). Impellers usually have blades with airfoil cross-sections.
