Summary

The purpose of this study was to investigate the influence of the direction and continuous time of airflow on thermal comfort. Ten collegiate female subjects were exposed to airflow of twenty types. The air velocity of fluctuating airflow counted for 0 to 0.8 m/s (mean 0.3 m/s) and air velocity of uniform airflow for 0.3 m/s. The air temperature was kept constant at 28 °C. Relative humidity was kept constant at 50%. Two fans were located in front of and behind the sedentary subjects. The skin temperatures were measured, and the subjects were asked about thermal sensation, thermal comfort and evaluation of airflow. The skin temperatures fell in many places that were exposed to airflow, and there were some statistically significant differences. The dispersion of general thermal sensation votes was small. The most numerous reports in general thermal sensation were "0:neutral" at any condition. The airflow which blew longer from in front than behind obtained a higher comfort sensation vote.
