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, T_b was set 10℃ 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.
