 Full text | Abstract: The humidification phenomenon of the space closed by the body and clothing fabric was investigated using physical simulation of mass and heat transfer on a Hy-tester computer system. Measurements were performed at fixed conditions, including water supply rate, temperature and pressure gradients. The humidity of air in the closed space above the specimen was maintained at a fixed level by using an adjustment drying system with a pump. Changes of air properties, such as relative humidity and temperature under the specimen versus time, were measured and recorded. On the basis of the model of water vapour concentration in a cell closed by the specimen and the model of drying pump voltage, a kinetic balance of water vapour mass was determined. The kinetic curves of humidification flux obtained, sorption flow and transferred flow are characteristic for tested materials and they display the moisturising and drying process of a clothing microclimate. |
