Influence of sidewall cold radiation on local thermal comfort of human body

 Taking twenty volunteers dressed in winter indoor clothing with 1.0 clo as study objects, studies the influences of sidewall cold radiation conditions on local and overall physiological and subjective responses at neutral ambient temperature of 22 ℃. Analyses the relationships between overall thermal sensation and local thermal sensation, skin temperature and thermal sensation, local thermal sensation and thermal acceptability. The results show that the lower-leg has the lowest local thermal sensation vote and is the most uncomfortable part of the body. The local (except the chest and arm) skin temperature has a strong linear relationship with the thermal sensation. There is a strong linear relationship between the overall and the local in thermal sensation and thermal comfort. Based on the influence weight of the local on the overall, establishes a human thermal sensation and thermal comfort evaluation model suitable for the sidewall cold radiation environment.
