Constant Air Volume Type VAV

Download Product Catalogue for Constant Air Volume Type VAV


AEROVAC Constant Air VolumeType VAV is a type of Heating, Ventilating & Air Conditioning (HVAC) System. Designed to achievesteady level of airfow at two different temperatures, and maintains a standard air pressure throughout the system. Constant airvolume is achieved through a differential sensing system by regulating the CAV damper. The differential pressure is measured atthe flow grid then trasmitted to the actuator through a controller and adjusting the control damper thereby keeping the air volumfow constant with the set value.
