Fluctuating air movement has possibility of improving the quality of hot or warm thermal environment. The purpose of the present study is to investigate it by subjective experiment. Conclusions are follows, i) Mean convective heat tranfer coefficient of constant air movement for sitting man is indicated. ii) Physical and phsiolosical effects of fluctuating air movement is indicated by mean convective heat tranfer coefficient for sitting man. iii) Psychological effects of fluctuating air movement is indicated by the relationship between mean body temperature with thermal and comfort sensation, iv) Thermal and comfort sensation of fluctuating air movement is predicted by physical, phsiolosical and psychological effects.thermal comfort
