Investigation of Human Thermal Comfort in Sleeping Environments Based on the Effects of Bed Climate

摘要

The purpose of this study is to investigate the thermal environment while sleeping through experiment. Twelve health volunteers were selected as subjects. The indoor thermal environment and bed climate were obtained via objective measurement, and the subjective thermal perceptions were collected by questionnaires. The results showed that thermal evaluations on face perceived comfort when exposed to the indoor temperature in the range of 11.3 ℃ to 21.9℃; it was a range of 30.3 ℃ to 32.5 ℃ for a comfortable bed climate which directly affected the body trunk. This may because the bed cover allowed of an isolated high bed climate temperature, and facilitated a better thermal sensation under low temperature indoor environment. The results may contribute to a more preferable thermal design for civil building, and be beneficial for energy conservation.
