air-conditioning system
Also known as: VAV system

Quick Summary

A variable air volume (VAV) system is a method used in air-conditioning to control the temperature in occupied spaces by supplying conditioned air in varying amounts as needed. This approach is widely implemented in both high-rise and low-rise commercial or institutional buildings.12

VAV systems offer energy economies compared to constant volume air supply methods. In these systems, conditioned air is delivered through ductwork, and thermostats within the space regulate the amount of air supplied to maintain the desired temperature. This allows for efficient and responsive climate control within buildings.1
