The acceptable air velocity range for local air movement in the tropics

This article deals with the perception of locally applied airflow from personalized ventilation air terminal devices by tropically acclimatized people. During the experiments, 24 subjects (male and female) were exposed to local airflow from the front and towards the face at six air velocities (from 0.15 up to 0.9 m/s), at ambient temperatures of 26 C and 23.5 C and local air temperatures of
26 C, 23.5 C and 21 C. During each combination that was maintained during 15 minutes, the subjects responded to questionnaires on their thermal and draft sensations.
The results are presented. That research suggests that there is a need for more research on preference for air movement in the hotter and more humid parts of the world.
