CO2 Control In School Classrooms - AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation 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 ...

Inadequate Ventilation and High CO2 Levels

The legal exposure limit is a TWAEV (time weighted average exposure value) of 5000 ppm which will unlikely be reached outside of heavy industry (Regulation 833 Control of Exposure to Biological or Chemical Agents). Levels of 600-800 ppm are typical in office environments. Guidelines suggest CO2 levels do not exceed 1000 ppm (700 ppm above outdoor levels), the ASHRAE action level. Some ...
