Abstract:

Clothing ventilation air exchange can be deduced from energy balance results of clothing insulation studies on dry and sweating thermal manikins over a range of air speeds. This paper demonstrates that energy balances at the skin of the clothed dry heated manikin operating in a 20 deg. C 50 RH environment can determine the energy carried away by ventilation air. The volume flow rates are calculated assuming intrinsic insulation is unchanged by air speed and that the ventilation air leaves the clothing system at skin temperature. Similarly energy balances on the clothed sweating manikin operating in a 35 deg. C 50 RH environment air temperature skin temperature can determine the latent energy carried away by the ventilation air assuming the ventilation air leaves saturated. Clothing ventilation rate estimates at three air speeds determined on the dry and sweating manikin are compared. Demonstration is conducted on military clothing with and without body armour and on fuel handlers protective coverall.
