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.

摘要： 为了提高夏季办公室工作人员的热舒适性,在不使用空调制冷设备的情况下,设计开发了3款微型风扇阵列通风服。该通风服由通风系统和基础服装组成,风扇置于服装不同的部位。在气候室模拟了夏季办公室工作环境,采用真人着装实验,通过测量客观和主观指标,对通风服进行了降温效果和热湿舒适性评价。结果表明:微型风扇阵列通风服轻便,穿着舒适;3款通风服均使衣下温度下降;受试者穿着通风服与对照组相比,平均皮肤温度、平均躯干温度均降低,耳道温度不存在显著性差异,对平均皮肤湿度影响不明显,同时受试者的热感觉、湿感觉、热舒适度也显著优于对照组。前后均带有风扇的通风服对躯干降温效果最好,与其风速最大有关,达到较为显著的改善人体热舒适的效果。
