The body temperature of five normal men was measured, and the changes of body surface temperature under different environmental conditions were investigated. It was concluded that chest, back and forehead were the areas with the highest body temperature, and the mathematical model of refrigeration system with "people-cooling shielding clothing-exterior" as the core was established. The cooling effect of shielding clothing under various environmental conditions was studied and simulated. It is found that the introduction of phase change agent or electric fan in the shield near the chest and back can effectively reduce the body temperature and improve the comfort of the body.展开更多
