Effective Thermal Insulation of Body Segments by Summer Clothing

The aim of this study is to create a database of the effective thermal insulation provided to thebody segments by various types of summer clothing (Rclei). In a climatic chamber with calmair conditions (v ? 0.15 m/s), Rclei was obtained for 52 garments and 97 ensembles. In themeasurements, a female thermal manikin that had twenty segments was arranged in a sittingposture. In the chamber, operative temperature was set to 27.0C, 25.0C, and 24.0C for anude manikin, a manikin clothed in a garment, and one clothed in an ensemble, respectively.Rclei were calculated for the nine segmentsthe chest, back, abdomen, buttock, upper arms,forearms, thighs, legs, and feet. The common regression for all the body segments, Rclei.en =0.784 ?Rclei.gr, was proposed for estimating the Rclei for the ensembles (Rclei.en) from the sum ofthe components Rclei (?Rclei.gr).
