Sick Classrooms Caused by Rising CO2 Levels

· Sick Classrooms Caused by Rising CO2 Levels. “Exposure to CO2 can result in drowsiness, eye irritation, and inability to concentrate. If a ventilation system provides inadequate freshair intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.

CO2 Dashboards for Ventilation Monitoring in Schools

While the project began by looking at the impact of the ARated building on IAQ, and uncovered some serious issues with respect to the CO2 levels in classrooms, it was quickly realised that this method could also be used to monitor and control the ventilation levels in classrooms with respect to the spread of COVID19. This has been consolidated recently by John Wenger of the UCC school of ...

CO2 Control In School Classrooms AirTest Technologies

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 ...

classroom example. Therefore, the desired differential between indoor and outdoor CO2 concentrations remained constant, too, regardless of how many people actually occupied the zone (Figure 1). By controlling to this constant differential, Cs – Co, CO2based demandcontrolled ventilation maintains the same perperson ventilation rate (Vo) to

Carbon dioxide test procedure ProjectMask Delft ...

Screw the control valve for the CO2 completely shut. Open the CO2 tank main valve (nothing should flow). Using the measurements read out of the sensor, increase the flow using the CO2 flow control valve slowly until 5% is reached (50,000 ppm or 5000 readout from the SprintIRWF20 sensor). Check this value during each settling period. Stop the measurements. Test: Place the fan and make sure ...

Easy solutions for indoor air problems at schools Vallox

Classroom and spacespecific ventilation is a costeffective and quick way to improve the indoor air quality at schools and daycare centres. Humidity, carbon dioxide, and smells caused by people are easy to remove by boosting the ventilation. Also structural impurities can be removed by controlled supply and extract air ventilation that does not create underpressure in the rooms. In a ...

Why measure CO2 in HVAC applications? |

This device allows occupants to easily monitor and control CO2 levels specific for smart homes, classrooms, offices and commercial buildings. Do note, that outdoor CO2 measurement is not required for LEED credit, and may only be useful under certain scenarios. Companies seeking LEED certification for new buildings should consult a LEEDcertified engineer for the most recent rules. Also note ...
