Demand control ventilation systems: performances of CO2 detection

Résumé et principaux résultats

Publication à la 24e Conférence de l'AIVC, Washington D.C., USA, 12-14 October 2003.
This paper presents laboratory tests methods to assess the performances of CO2 sensors for the control of ventilation systems, the working performances of these sensors, and particularly the long term stability in a meeting room, and a methodology to assess the performances of CO2 DCV system in French technical agreement.
The main results of this study are: it is easy to characterize (to calibrate) the sensors; the long term stability is good enough; the slight concentration gradient makes the choice of sensor location easier.
