Evaluation of a vertical displacement ventilation system
AbstractThe effectiveness of a vertical displacement ventilation system was evaluated when contaminants including tobacco smoke were present. Air supply was through a perforated floor and carpet. System performance was evaluated using ADPI (Air Diffusion Performance Index), percentage dissatisfied due to draft, vertical temperature difference, and air change, and contaminant removal indices. Gaseous contaminants were simulated with tracer gas. Cigarettes and occupants also generated particulates, CO2, CO, and TVOC (total volatile organic compounds). Several combinations of supply air flow rate and thermal loads were evaluated. The risk of draft was found to be negligible. The air change effectiveness for the room varied from 126 to 145% and the contaminant removal effectiveness for the occupied zone varied from 80 to 700%.
