Effects of Chairs on the Thermal Insulation of Nude Skin Surface

摘要

Thermal insulation of clothing is usually measured using a standing thermal manikin. In real life, however, people often sit on chairs and thermal insulation of the nude skin surface and that of clothing should be affected by the chairs. The purpose of this study is to determine the effects of chairs on thermal insulation of the nude skin surface. Seventeen chairs, usually used in an office, were selected for this study. A thermal manikin was used for the thermal evaluation of the chairs. It was found that the area of the back of the chairs influenced the thermal insulation of the manikin in general and the thermal insulation of the back of the manikin in particular as well as the contact area between the chair and the skin surface.
