Abstract

It is necessary to control the room temperature for comfortable and deep sleep during a tropical night. We need to investigate thermal transport and parameter between human and environment for comfortable sleep. Therefore this study is performed to evaluate the comfortable room temperature based on the change of skin temperature under variations in thermal conditions and several reports. Five female subjects of 20~22 years with similar sleeping pattern were participated for the experiment. The subjects arrived in chamber at 9 pm and adapted to thermal circumstances during 2 hours. The sensors was sticked in body for skin temperatures. If subjects fall asleep in chamber, lights off and then sleep during 8 hours.As results, indoor temperature range for comfort sleep was $23.9{\sim}28.4^{\circ}C$ based on comfort mean skin temperature. But considering transition of time, minimum indoor temperature was $21.6^{\circ}C$, $22.9^{\circ}C$, $24.1^{\circ}C$, $23.9^{\circ}C$ and maximum indoor temperature was $28.2^{\circ}C$, $30.1^{\circ}C$.
