Thermal Climate in Confined Spaces- Measurement and Assessment using a Thermal Manikin 881111

Thermal climate in automobiles, buses, trucks arid indoors has been evaluated using a newly developed thermal manikin. Heatman. Test results indicate a noticeable difference among cars. In a cold environment, the general problem is distribution between wind screen and lower part and asymmetry for right and left sides of individuals. In a warm climate, air is often distributed unevenly, thus resulting in discomfort. The results are shown as heat flow (W/m2) from 36 areas of the body or as equivalent (sensed) temperatures. The PMV-PPD comfort index is also derived from these measurements.Measurement and assessment of thermal climate using a thermal manikin will make it possible to evaluate the best solution for thermal control. It can also be used to measure clothing and chair insulation.
