Demand-Controlled Ventilation (DCV) - SVACH

DCV controls use CO2 as a surrogate. The term surrogate means that ventilation controls use CO2 concentration to control the concentration of other occupant-related pollutants. Designers assume that controlling CO2 controls all occupancy-related pollutants. CO2 sensors are relatively precise, reliable, and inexpensive compared to other types of DCV pollutant sensors. Occupancy sensors count ...
