An investigation of air inlet types in mixing ventilation

The aim of that research is to obtain contaminant concentrations in a room, to perform qualitative and quantitative comparison for a wall jet air inlet and a ceiling diffuser air inlet, and to determine more efficient inlet and outlet configuration. The effect of air inlet types in mixing ventilation was investigated in an experimental room under two conditions, with no occupant and with an occupant present north of the source. The results have shown that the air inlet type is an important physical determinant to the distribution of airborne contaminant concentrations. And this investigation enhanced understanding of the interactions between concentration field, airflow and air inlet types.
