Human response to five designs of personalized ventilation

The objective of the study was to investigate the human response to five air terminal devices (ATD) for a personalized ventilation system (PVS). All the systems were tested in an experimental office, they all improved the perceived air quality at the workstation. The round movable panel was the ATD most preferred for the subjects, among the systems studied : it provided high perceived air quality and thermal comfort for subjects. The thermal environment created with all the systems was assessed as acceptable.
