| 中文摘要: |
| 在寒冷的室内环境中，营造满足个性化需求的局部热环境有可能保持甚至提高人员的舒适感。考虑到改善身体下半部分冷感觉对于改善整体热舒适的重要性，通过模拟冬季室内冷环境，采用5种加热措施（单独穿戴加热鞋垫、加热腿带，联合穿戴前述两种加热装置，单独使用电辐射器、暖风机）对12℃和14℃气候室中26名受试者的身体下半部进行加热，研究对人员整体热感觉、整体热舒适以及皮肤温度等的影响。结果表明：身体下半部局部加热可显著改善受试者整体热感觉；较高环境温度下局部单独加热脚部和腿部对整体热感觉的改善效果会受到限制，不会影响整体热舒适；使用电辐射加热器能发挥更大的改善效果，但会造成小腿前后部受热不均匀。 |

| In cold indoor environments, creating a localized thermal environment that meets personalized needs may maintain or even improve personnel comfort. Considering the importance of improving cold sensation in the lower part of the body for improving overall thermal comfort, the effects on the overall thermal sensation, overall thermal comfort, and skin temperature of the personnel were investigated by simulating a cold indoor environment in winter and heating the lower part of the body of 26 subjects in 12°C and 14°C climate chambers by using five types of heating measures (wearing heating insoles, heating leg straps, wearing the front two heating devices in combination, using electric radiation heater and warm air blower alone).The results indicate that local heating to the low parts of the body can significantly improve the overall thermal sensation of the subjects; The improvement effect of locally heating the feet and legs separately at higher ambient temperatures on overall thermal sensation will be limited and will not affect overall thermal comfort; The use of electric radiation heaters can have a greater improvement effect, but it can cause uneven heating in the front and back of the calves. |
