The purpose of this study was to determine the effects of active clothing microclimate regulation on human thermophysiological response. For the study method, we developed a prototype for a personal chiller and conducted experiments on seven healthy male university students under various conditions. Subjects with a hot environment clothing microclimate (34°C; 80%R.H.) were moved to an air conditioned environment (28°C; 50% R.H.) and allowed to recover their microclimate under the following two conditions: (1) while sitting at rest (experiment N) with no cooling and (2) after 10 minutes of active clothing microclimate regulation with a personal chiller (experiment P; 25°C; 45% R.H.). The results of the two experiments were then compared. The increase in core body temperature was controlled better in experiment P than in experiment N. A lower mean skin temperature was better maintained, and the warm-cold sense of the entire body recovered more quickly in experiment P compared with experiment N. These results indicated that the use of a personal chiller reduced absolute humidity and removed residual moisture from within the clothing of the subjects
