Abstract

A cubic experimental chamber with 2.5m of sides was designed to measure the impact of the ventilation on the indoor particle concentration. Particles of 0.3 - 15µm diameter were used. Two ventilation parameters were studied: the ventilation rate (0.5 and 1.0 ach) and the inlet and outlet locations (four different strategies were tested). Results show that the ventilation acts differently according to the particle size. For small particles (particle diameter lower than 5µm), deposition depends both on the airflow path within the room and on the strength of the ventilation. The effect of the inlet and outlet locations is less notable for coarse particles. This experimental study reveals that the ventilation strategy has to be well adapted to the
