Abstract
An energy-efficient ventilation system comprises a ventilation fan, ductwork, system controller, and a plurality of ventilation points, each comprising a damper, a differential pressure sensor, a ventilation point controller, and a fume detector. When a ventilation point does not require ventilation, a signal is sent to the system controller to reduce the ventilation fan speed thereby using only as much energy as is needed to provide service to the ventilation points that need ventilation. The fume detector, damper, and differential pressure sensor for each ventilation point are used to determine whether ventilation is needed at a ventilation point and to control the ventilation point accordingly.
