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 ...

Why Measure Carbon Dioxide Inside Buildings?

2 measurement taken in the same classroom during the last period of the day. Assuming the ventilation rate and occupancy of the classroom have remained fairly consistent throughout the day, it is reasonable to assume that a CO 2 concentration below about 1,000 ppm indicates 15 cfm per person, assuming also that the outside air CO 2 is in the 350 ppm range (650 ppm differential inside minus ...

Suggested CO Control Sequence Of Operation

2 Control Sequence Of Operation Installation Coverage: One sensor should be used for each zone of major occupancy or per air handling device if a number of devices serve a large zone. If occupancy density/patterns/usage are different in two adjacent areas each area should be considered a separate zone. Generally one sensor can serve up to 5,000 sq feet. Larger coverage is possible in theaters ...
