3668 -- Evaluation of Smoking Lounge Ventilation Designs PDF

Describes a study to test various air distribution systems for smoking lounges. Six variations on four configuration were tested - three diffusional systems, two displacement systems and one system that might behave as either a diffusional or displacement system. An occupant ballot was used to provide an indicator of air quality as it related to occupant comfort. Air motion and temperature were determined as they related to peoples' subjective evaluation of air quality. In addition, a number of air quality indicators were measured in real time during each experiment. Finds that smoking lounge air quality that is acceptable to the occupants can be attained by minor modifications of existing conventional air distribution systems.
