[Fundamental study regarding the characteristics of wetness under constant average skin temperature].
This paper deals with the characteristics of wetness under constant average skin temperature and its effect on the equal skin temperature lines. From the basic measurements of both environmental parameters and human physiological responses, the following results were obtained: Under the condition of constant activity level, clothing worn, air movement and constant average skin temperature, 1. there is a positive correlation between the wetness and the environmental humidity. 2. there is a negative correlation between the wetness and the air temperature. 3. there is a negative correlation between the wetness and the evaporative heat loss. 4. both the maximum and the minimum wetness values corresponding to each average skin temperature exist. The theoretical examinations regarding the above-mentioned items--the characteristics of wetness under the constant average skin temperature were extended, and we finally obtained the following; the locus of equal skin temperature is not a straight one but a curve on the psychometric chart.
