Examining the Value of C02 Sensors in Green Buildings ...

· When CO2 sensors are used with demand control ventilation (DCV) systems, the amount of freshair ventilation is controlled based on how many people are actually in a space at any given time. When CO2 levels rise with increased occupancy, more fresh air is introduced by opening dampers. CO2 levels fall as people leave, so the dampers close to reduce the amount of air that must be heated or ...

Carbon Dioxide (CO HVAC Basics Honeywell

systems with proportional control use a CO2 sensor signal proportional to CO2 level. Control begins when indoor levels exceed outdoor levels by a defined difference (100 ppm). Air delivery to the space increases proportionally to provide 100% ventilation rate. Compared to setpoint control, this approach allows faster system reaction to varying occupancy
