COMPARISON OF HUMAN RESPONSES TO FACE, CHEST AND BACK COOLING
Face, chest and back are the most sensitive and commonly exposed body parts for local cooling. The effects of face, chest and back cooling on human responses under the environment ranging from neutral to warm were investigated and compared systematically in the present study. Thirty randomly selected college-age male subjects participated in the experiment. They reported their local thermal sensations of each body part, overall thermal sensation and acceptability on voting scales during each exposure. It is shown that local thermal sensation is a 2-segment linear function of local skin temperature for face and chest, and a function of local skin temperature and ambient room temperature for back. The influencing factor of face, chest and back on overall thermal sensation is 0.61, 0.47 and 0.45. Compared with chest and back cooling, face cooling improves whole body thermal sensation while producing less non-uniformity, resulting in a higher improvement of thermal acceptability.
