Ventilation par déplacement : mesures et calculs concernant l'écoulement d'air dans les pièces.

Measurements and computations of room airflow with displacement ventilation.

Résumé

The paper presents a set of detailed experimental data obtained from measurements conducted for three typical room configurations: a small office, a large office with partitions, and a classroom. The distributions of air velocity, air velocity fluctuation, and air temperature were measured by omnidirectional hot-sphere anemometers, and contaminant concentrations were measured by tracer gas at 54 points in the rooms. Smoke was used to observe airflow. The data also include the wall surface temperature distribution, air supply parameters, and the age of air at several locations in the rooms. A computational fluid dynamics program was also used to predict the indoor airflow.
