Description

In order to use SET^* as a thermal index for the prediction of thermal sensation and the evaluation of thermal environment, it is necessary to clarify the correlation between SET^* and thermal sensation. In our previous paper (Part 1), the regression line between SET^* and the whole body thermal sensation was shown as a result of the winter subjective experiment, and then the sexual difference of the regression line and SET^* at neutral thermal sensation calculated from the regression line were examined. This paper (Part 2) discusses the seasonal difference in a correlation between SET^* and thermal sensation by comparing the results of the above winter subjective experiment and similar summer subjective experiment. The main results in the winter and summer experiments are shown as follows. 1) The seasonal difference was not found in the regression lines between SET^* and the whole body thermal sensation. 2) In both winter and summer seasons, the sexual difference was not found in those regression lines. 3) The zone of thermal neutrality for Japanese in which thermal sensation votes were from 4: slightly cool to 6: slightly warm was around 22〜26℃ SET^* through winter and summer seasons. 4) The seasonal difference in a percentage change of thermally neutral votes from subjects was small, and a SET^* range which gave more than 80% thermally neutral votes coincided with the zone of thermal neutrality, which was around 22〜26℃ SET^* as described above.
