Constant Variable air volume boxes – CAV

CAV application the terminals maintain the required constant airflow independent to inlet statis pressure.
CAV systems are often used due to their simplicity, low cost, and reliability in small buildings and residences.
CAV systems often have on/off control, rather than supply air temperature modulation, to vary their heating or cooling capacities to serve a single thermal zone.
CAV systems are usually used in spaces with large open areas having uniform loads like theaters, auditoriums and exhibition halls.
