THERMAL EFFECT OF AIR MOVEMENT VENTILATED BY CEILING INLET ON THE HUMAN PHYSIOLOGICAL AND PSYCHOLOGICAL RESPONSES

The effects of air movement from the floor to the ceiling on the human physiological and psychological responses were examined by the subjective experiments. In this study three male students were exposed to the combined eight conditions of air temperature (24℃ and 28℃) and air velocity (0.3m/s, 0.5m/s and 0.7m/s) under humidity 60%RH. To evaluate the effect of air movement on local position of the body, the corrected humid operative temperature HOTV was applied to the local position. There were high correlation between HOTV and the skin temperature on both of local positions and the whole body. The effect of air velocity could be represented by use of the air velocity effect index based on the thermal velocity field.
