Clothing Thermal Insulation for Typical Seasonal Clothing of Infant with Infant Thermal Manikin

摘要

Infants are less thermally adapted to their environment and can be considered as needing protective measures against thermal environments. It is not ethical to conduct subject experiments on infants. Thermal insulation in clothing is an essential control coefficient for the evaluation of the thermal environment of an infant. A thermal manikin can be used as an alternative method for carrying out experiments and to control the thermal manikin based on heat balance. The purpose of this study was to clarify the thermal insulation of infants’ clothing. An infant thermal manikin was used to clarify the thermal insulation (Icl style="font-family:Verdana;">) of typical summer, mid-season, and winter cloth style="font-family:Verdana;">ing combinations for infants. The thermal insulation of typical seasonal clothing combinations was 0.30 clo for summer clothing, 0.57 clo for style="font-family:Verdana;"> mid-season clothing and 1.02 clo for winter clothing. It was clarified that it is essential to consider clothing conditions by taking into account differences in posture and to define the clothing thermal insulation ( style="font-family:Verdana;">I _{style="font-family:Verdana;">cl} style="font-family:Verdana;">) when designing and evaluating thermal environments. When designing and evaluating an infant’s thermal environment, it is essential to investigate using data from infants.
