Human Thermal Comfort Study Based on Average Skin Temperature

As an important evaluation index of indoor environmental quality, human thermal comfort is affected by various factors. As human physiological signal, the skin temperature is closely related to human thermal comfort. To investigate the model's mapping relationship between the skin temperature and the human thermal comfort, the skin temperatures of six parts of human body were chosen as research object, the linear mapping relationship between the average skin temperature and the human thermal comfort was analyzed by using Fisher discriminant method under five different experimental conditions and subjective voting. As a result, the mathematical evaluating model between the average skin temperature and human thermal comfort was obtained based on experiments. The results indicate the average precision of this model is high and the discriminant result is reliable, which provides valuable reference for human thermal comfort modeling under homogeneous environmental condition.
