Abstract
In this study, the physiological and psychological effects of preferred air velocity on the human body were investigated. The air temperatures were 26°C, 28°C and 30°C, and the relative humidities were 30 %, 50 % and 80 %. The subjects were 10 healthy women sedentary in summer wear, who could regulate air velocity for 60 minutes according to their feeling of comfort. The results were as follows : (1) Increase in air temperature and humidity was compensated by increase in air velocity. (2) At the preferred air velocity, the subjects reported "slightly cool", and "comfortable". (3) At 26°C and 28°C, the preferred air velocity was faster than the air velocity predicted by SET* and Fanger's comfort equation.
