Abstract: In order to improve the thermal comfort of office workers in summer, we design and develop three types of micro-fan array ventilation clothing without using air conditioning and refrigeration equipment. The ventilation clothing is composed of a ventilation system and basic clothing, with the fan being placed in different parts of the clothing. The summer office working environment was simulated in the climatic chamber, and human subject dressing experiments were conducted to evaluate the cooling effect and thermal-wet comfort of the ventilating clothing by measuring objective and subjective indicators. The research results show that the micro-fan array ventilating clothing is light and comfortable to wear; all the three types of ventilating clothing reduce the temperatures under the clothes; compared with the control group, the average skin temperature and torso temperature of the human subjects wearing ventilation clothing decrease while the subjects' thermal sensation, wet sensation, and thermal comfort are much more better, though the ventilating clothing has an insignificant influence on auditory canal temperature and skin humidity. On the whole, the ventilating clothing with both front and back fans has the best cooling effect on the torso and significantly improves human thermal comfort, which is related to the maximum wind speed.
