Research Abstract

In this study, we recorded psychophysiological responses of human to evaluate the differences of thermal comfort in different indoor thermal environments: a household air conditioner versus a radiant heating and cooling system. First, we conducted an experiment on cooling. There were significant differences in perception time and brain wave amplitude (especially beta and gamma waves) between those two systems. Second, we conducted an experiment on heating. There were also significant differences in brain wave amplitude (especially alpha wave). From these results, we showed the psychophysiological differences of comfort between those systems about both cooling and heating.
