Occupancy-based demand controlled ventilation system

摘要

In a demand control ventilation (DCV) system, ID codes of tags worn by occupants are detected in each room by a tag detector and wirelessly communicated to a zonal occupancy compiler. The zonal occupancy count arrived at by the compiler is transmitted to a DCV microprocessor, which interfaces with the ventilation controller of the building's HVAC system and sets the zonal ventilation rate based on the occupancy count and applicable ASHRAE standards.
