  • 摘要:

    The objective of this paper is to analyze the simultaneous heat and moisture transfer from a heated plate on which a wet filter paper is placed to simulate sweaty skin. A parallel model of sensible and latent heat transfer is used for the analysis. In Part 1, the sensible heat transfer rate was measured without placing a wet filter paper on the heated plate (Experiment I). The sensible heat transfer resistance R t, one of the components of the parallel model, was derived in Part 1 from a series model of the resistance of the air layer under the fabric, the resistance of the fabric itself, and the resistance of the fabric surface to the surrounding environment. As for the latent heat transfer, the same series model was used to analyze the water vapor transfer resistance W t, measured in Experiment II. These experiments were conducted under two sets of conditions. In Experiment II, the plate temperature T b, was set to the same temperature as the environmental air temperature T a, the measured heat transfer rate was taken as the pure latent heat of evaporation of water, and then the water vapor resistance W t was evaluated. In Experiment III, Tb was set 10°C higher than T a and the measured heat transfer rate Q w includes both sensible and latent heat. The simultaneous heat and moisture transfer was described by an equation of R t and W t, which include the parameters for air, thermal and water vapor resistances of materials, air gap length and wind velocity.
