CO2 In the Classroom |

In addition to indoor pollutants, studies also found that carbon dioxide levels rose in sealed classrooms throughout the day. While humans can learn to adapt to high levels of CO2 over long periods (for example, in a submarine) over short periods, even moderate increases in CO2 will result in children who are tired, have headaches or cannot concentrate.

CO2 Control In School Classrooms sensors for commercial ...

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...

"Ventilation Control Options" Modular Building Institute

CO2 Sensors CO2 is a very stable trace gas. When exhaled by the occupants, CO2 can then be used to control ventilation systems. Many codes/standards require either a minimum ventilation rate of 15 cfm per person, intake and exhaust, continuous ventilation during occupied times, or a maximum CO2 of 1000 parts per million (ppm) (ASHRAE) as the set point. CO2 sensors can open the ventilation ...
