HVAC Design Overview of Variable Air Volume Systems
pdhonline.comVAV Systems – Benefits Here are a few of the advantages of VAV systems: 1. Efficiency – VAV systems are low on energy consumption. During lean periods, the air handling unit fan can run at a slower speed (through the use of a variable speed drive) and the amount heating and cooling mediums running through the coil can be reduced (through

www.energystar.gov8. Air Distribution Systems 8.2 Air-Handling System Types There are two types of air-handling systems: constant volume (CV) and variable air volume (VAV). In a CV system, a constant amount of air flows through the system whenever it is on. A VAV system changes the amount of airflow in response to changes in the heating and cooling load.

At design cooling conditions, primary airflow required for the ACBs serving this space is 60 percent less than for the conventional VAV system. However, this does not translate to a 60 percent reduction in fan energy use, as will be discussed later in this EN under the claimed advantage 3 section.

The fan coil unit provides sensible cooling or heating at the zone (Figure 2). This configuration has several advantages over a conventional VAV system. Decoupling the
