On the basis of the wearing test in the controllable artificial climate room, the dependencies of the climate in the room on the clothing climate were discussed.
1) Each Temp. T(C) and relative humidity RH(C) of the clothing climate increases and decreases abruptly just when worn only the next-to-skin wear. And by adding the numbers of worn clothes, T(C) increases gradually, but the change of RH(C) comes firstly by the moisture transmission through the worn clothes under the exsistense of a certain variance between relative humidity RH(R) in the room and RH(C). For example, in case of clothes having 0.937 K pa·s/m in resistivity of air-permeability, the moisture transmission through the worn clothes comes when having the variance about 5%RH.
2) Each part such as the substernale, the side at navel hight and the scapulae point of the body has its own T(C) which relates to the skin temp. at each part of body.
3) The increase of T(C) is a factor to decrease RH(C), and the insensible perspiration and sweating are the factors to increase RH(C) undoubtedly.
But T(C)=32.5℃ and over, the latter factor gets ahead of the former one, and the sharp increases of RH(C) perhaps resulted from sweating of the pannel were observed.
4) By wearing the clothes, the clothing climate was formed to astringe T(R) and RH(R) to our comfort level. But temp. T(R) in the room and RH(R) effect on the largeness orders T(C) and RH(C) respectively within their astringed ranges. And the slight controls of T(C) and RH(C) owe much the worn condition such as the qualities of clothes and how to wear one garment over another.
