The purpose of this paper is to investigate the relationship between human thermal sensation and comfort sensation during exposure to thermal transients. Experiments were conducted under the following conditions. Five young male subjects in sedentary posture were exposed to 15, 18, 23, 25 and 30°C air temperature for 90 minutes following one hour exposure to 23°C air temperature. The following results were obtained. 1) Significant difference was not observed between 5 minutes exposure and 90 minutes exposure in relation to air temperature and thermal sensation vote. However, there was a difference in relation to exposure time between thermal sensation vote and comfort vote. 2) Change of thermal sensation is probably greater than that of comfort sensation when air temperature suddenly changes. However, change of comfort sensation is greater than that of thermal sensation throughout exposure time in constant temperature after air temperature changes. 3) Subjects vote their sensation which is warmer than thermal neutral when they feel most comfortable, because experiments were carried out in winter.
