Improving Indoor Air Quality with Cubic NDIR CO2 Sensor for DCV Systems

How do High Accuracy CO2 Sensors Help Maintain a Comfortable Indoor Air Environment?

Indoor air quality is essential in closed spaces with high occupancy levels. When the indoor CO2 concentration increases, the indoor air quality will be substandard, and occupants will gradually experience physical discomfort if the condition of high CO2 concentration continues. Especially when indoor CO2 concentration exceeds 1000ppm, people will feel uncomfortable. Therefore, a CO2-based DCV system is fundamental, as it could help maintain a comfortable indoor air environment.

DCV is a kind of effective control system used in fresh air systems to improve indoor air quality by automatically adjusting the ventilation rate. The functionality relies on strategically placed CO2 sensors, which provides continuous and precise monitoring of indoor CO2 levels within building spaces. Usually, before the CO2-based DCV system starts running, the corresponding indoor CO2 concentration threshold is set in advance, and the set thresholds are generally in accordance with ASHRAE standards. When the CO2 concentration exceeds a set threshold, the control unit will send a control signal to the fresh air system to increase ventilation, ensuring a healthy and comfortable environment for occupants. Once the CO2 concentration drops below the set CO2 threshold, the fresh air system will reduce indoor ventilation.

Therefore, CO2-based DCV systems can effectively manage indoor air quality through regulating ventilation volume. The flexibility of CO2-based DCV systems depends heavily on consistently accurate CO2 concentrations.
