This study investigated the perceptual and physiological responses of 10 college-aged subjects to square wave airflows of different cycles (2 min, 10 min and 30 min) under different temperature levels (28 and 32 ). Main conclusions are as follows:(1) The mean pleasantness was highest in the condition of 32℃ air temperature with square-wave airflow (10-min cycle).(2) The mean thermal sensations reported by subjects were lower than corresponding PMV values, indicating the cooling effect of dynamic airflows on human thermal comfort in warm environment.
