Thermal Comfort Evaluation of Clothing using Thermal Mannequin with Sweating and Walking Function

We discussed the usefulness and problems of the thermal comfort evaluation of clothing using a thermal mannequin with sweating and walking function. The mannequin is able to supply liquid water to the skin surface from 141 pores corresponding to the sweat glands, and simulates walking motion. The distribution of surface temperature of the mannequin was approximated to that of human skin temperature. We determined the surface thermal resistance of nude mannequins during standing, walking, and sweating. Two types of waterproof jackets (made of regular or breathable waterproof fabrics) and two types of T-shirt (made of cotton or polyester) were used as test garments. The thermal resistances of these clothing were measured. There was no forced convection during walking because the mannequin did not move. With thermal resistance, it is important that the microclimate (temperature and humidity within clothing) between the surface of the mannequin and clothing is measured when evaluating the thermal comfort.
