Some Studies on Effect of Particle Source Locations on Ventilation Effectiveness in Displacement Ventilated Room (142285)

Abstract : Ventilation effectiveness is the ability of the ventilation system to fulfill the design goals such as provision of fresh, healthy air to the occupants, dilution and removal of contaminants from the occupied zone of the mechanically ventilated room. Computational fluid dynamics (CFD) has become an efficient tool for determining the airflow, heat transfer and contaminant transport in the enclosed room environments and for wide range of other HVAC&R applications. However, these CFD studies remain less relevant and useful unless and until these are backed up by proper experimental studies. Factors such as outdoor air quality, airflow rate, air supply method, moisture content, thermal environment and contaminant source location have greater impact on ventilation effectiveness. In this paper, the effect of contaminant source location on ventilation effectiveness in a displacement ventilated room is investigated. Both experimental and numerical approaches are used. The results indicate that the contaminant removal effectiveness in occupied zone is higher if the contaminant source location is in the room as against the source location in the supply air and the contaminant removal effectiveness in breathing zone is higher if the contaminant source location is in the supply air as compared to contaminant source location in the room
