| 为探究人体在典型劳动姿势时着装不同管路结构矿用通风服所形成的衣下非均匀空间分布对人体热舒适性的影响,通过真人着装试验测量人体各个部位皮肤温度并进行主观评价,分析不同环境温度、不同管路结构通风服在抬臂、弯腰典型劳动姿势时人体的热舒适性。结果表明：在同一抬臂姿势,同一环境温度条件下,人体各个部位皮肤温度变化差异不大；在抬臂不同角度时,在同一环境温度下人体不同部位皮肤温度变化差异较大。在同一劳动姿势下,由于环境温度较高且逐渐升高,人体对吹风感知程度逐渐下降,人体热舒适性逐渐降低；在同一环境温度、管路结构下,随着抬臂角度增加,人体较舒适、吹风感较强；横向型管路对人体降温效果较平稳,各部位皮肤温度较平衡,在抬臂、弯腰时人体热感觉与吹风感较舒适。 |

| In order to explore the influence of non-uniform spatial distribution under clothing formed by wearing different pipeline structure mine ventilation clothing on human comfort in typical working postures, the skin temperature and subjective evaluation of various parts of the human body were measured by human dressing test, and the thermal comfort of human body in typical working postures of arm lifting and bending was analyzed under different ambient temperatures and different pipeline structure ventilation clothing. The results show that under the same arm lifting posture and the same ambient temperature, the skin temperature of each part of the human body does not change much. When the arm is raised at different angles, the skin temperature changes of different parts of the human body at the same ambient temperature are quite different. Under the same working posture, due to the high and gradually increasing ambient temperature, the human body "s perception of blowing gradually decreases, and the human body "s thermal comfort gradually decreases. Under the same ambient temperature and pipeline structure, with the increase of arm lifting angle, the human body is more comfortable and the sense of blowing is stronger. The transverse pipeline has a stable cooling effect on the human body, and the skin temperature of each part is relatively balanced. The human body "s thermal feeling and blowing feeling are more comfortable when lifting the arm and bending the waist. |
