What Is Variable Air Volume?

required to move this air. The amount of energy saved depends on the method

 

the air volume reduction creates an opportunity to reduce the fan energy

 

used to modulate the capacity of the fan (to be discussed in Period Four).

 

Second, the reduced airflow across the cooling coil causes the refrigeration

 

system to throttle back in order to stabilize the primary air temperature. In turn,

 

this results in a reduction in refrigeration energy compared to full load.

Another reason for VAV is to cost-effectively provide improved comfort. A VAV system is capable of controlling space temperature in many spaces with dissimilar cooling and heating requirements, while using only one central air handling unit (AHU). This is accomplished by providing one VAV terminal unit and thermostat for each independently controlled space. When the sun is beating against the west side of the building in the late afternoon, a VAV system can provide an increased amount of cool supply air to keep the spaces on the west exposure comfortable, while throttling back the airflow to the spaces on the east exposure so as not to overcool them.
