摘　　要：建筑围护结构对室内热环境与人员热舒适影响巨大,合理设计围护结构对提升建筑节能性能与室内热环境具有重要作用,也是建筑热工设计的关键。GB 50176—2016《民用建筑热工设计规范》以外墙内表面最高温度、外墙内表面温度与室内空气温度的温差作为隔热、保温设计的指标,热舒适依据不足。此外,传统热舒适理论仅适用于均匀稳态环境,对于围护结构和供暖空调设备形成的不均匀辐射环境下人体的热舒适研究尚属空白。从人体热舒适角度出发,结合冷、热墙暴露实验结果与PMV模型,发现满足20%热不可接受百分比的热感觉范围为-0.2~0.5,得到冬季室内温度为18℃时,满足热舒适需求的外墙内表面温度与空气温度的温差为4.4℃,夏季室内温度为26℃时,满足热舒适需求的温差为5.4℃。The performance of the building envelope has a huge influence on the indoor environment and occupants’ thermal comfort. It is the key to building thermal design that optimizing building envelope to improve building energy-saving performance and indoor environment. The Thermal Design Code for Civil Building recommends the limits on building envelope by the temperature difference between the surface temperature of exterior walls and indoor air temperature, which is lacking evidence of thermal comfort. However, the traditional thermal comfort theory is only applicable to a uniform steady-state environment. There is little research on human thermal comfort under the asymmetric radiation environment formed by the building envelope and heating and air-conditioning equipment. Based on human thermal comfort, the study combined the experimental data and the PMV model and found that the cool wall and warm wall on human thermal comfort significantly affected human thermal comfort. The range of thermal sensation satisfying the 20% thermal unacceptable percentage is-0.2~0.5. When the indoor temperature was 18 ℃ in winter, the comfort limit of the temperature difference is 4.4 ℃. And when the indoor temperature is 26 ℃ in summer, the comfort limit of the temperature difference is 5.4 ℃.
