Demand Controlled Ventilation (DCV) systems: performances of infrared detection

Résumé et principaux résultats

Publication à la 24e Conférence de l'AIVC, Washington D.C., USA, 12-14 October 2003.
For energy savings, DCV systems are more and more used in ventilation systems. In France, in non residential buildings, these systems are generally controlled by either a CO2 sensor, or an optical movement detection (infrared). The part of the study presented here was to determine laboratory tests methods to assess the performances of optical sensors for ventilation application. The point was to characterise them by checking their detection in front of some determined movements or events. Results on the different methods tested to characterise sensors and the best method chosen are given.
