Purpose of this study is first to show the effects of vertical air temperature differences on thermal comfort and physiological responses, and second to examine the acceptable vertical air temperature differences. In this experiments, 12 subjects (6 males and 6 females) were exposed at 12 test conditions. The subjects voted each 10 min, about his thermal feeling, and 7 skin surface temperature, the air temperature were measured every 20 second. From this experiments, it was found that the upper part temperature affects the thermal sensation more strongly than lower part temperature. In winter, the acceptable temperature differences drawn by this study are 3℃ in the case that the upper part temperature is higher than the lower part temperature.
