Transient response of the human-clothing system

Abstract 1. 1. A transient clothing model which considers the effects of adsorption and thermal capacitance on the dynamic thermal response of clothing was developed. 2. 2. Moisture adsorption and desorption by the fabric are the major factors that affect the transient response of clothing. 3. 3. This moisture can come from evaporated sweat or from the environment. 4. 4. The clothing model was combined with a modified version of the two-node thermal model of the human body. 5. 5. The combined model shows that, during transients, the mix of latent and sensible heat flow from the skin may differ considerably from the corresponding heat flows from the clothing surface to the environment. 6. 6. The alteration of the heat flows can have a significant impact on the thermal response of the body by changing the sweat rate required to achieve the heat loss necessary to maintain thermal balance.
