Abstract
Insensible perspiration is greatly related to the heat balance between the skin and environment, and the CO2 density in the space of clothing and skin is one of the factors representative of the condition of cutaneous respiration. Meanwhile we set the climate chamber in which we measured the CO2 density and the quantity of insensible perspiration excreted from the skin of the arms of four subjects comfortably clothed in, and also measured the CO2 density and the quantity of insensible perspiration in the space of clothing and skin around the chest under the different conditions of four clothing in respect of two materials and two types.
We studied the relation between the measured value and climatic factor. The results are as follows : 1) Insensible perspiration and CO2 exhaled from the skin were effected by not only ambient temperature but latent heat. 2) Maximum insensible perspiration from the skin was observed in medium climatic condition. 3) Material of clothing had an effect on the micro climatic condition of layer of air in the clothing. 4) The liner relation was found between dew point temperature and effective temperature. 5) With respect to the CO2 density in the space of clothing and skin, the bellow effect could be observed.
