| 摘要: |
| 为探索由月球表面特殊光热环境导致的驻人月球科研站围护结构传热过程与地球建筑的差异性,基于月球表面太阳辐射模型,根据有限差分法建立围护结构的传热模型,对影响内表面温度的物性参数、朝向等因素进行模拟分析。结果表明:当防热层、隔热层和阻气层分别取20 mm Nextel BF-20、240 mm Pyrogel 6650、20 mm Kapton时,水平屋顶内表面温度的波动范围为16.8~22.4 ℃；厚度和导热系数是影响围护结构传热性能最重要的因素,综合考虑建造成本与隔热性能,应尽量降低围护结构的厚度与导热系数,采用低密度、高比热的材料；内表面的对流换热系数与外表面的发射率直接影响围护结构的边界换热量,可结合不同朝向的辐射特点与热舒适要求,个性化定制具有差异化热惰性和外表面发射率的材料。 |

| Abstract: |
| To explore the differences between the heat transfer processes of the envelope of the manned lunar research station caused by the special solar-thermal environment on the lunar surface and those of the buildings on the earth. a heat transfer model of lunar building envelope was established based on the finite difference method and the model of the solar radiation on the lunar surface. Various factors affecting the temperature on the inner surface, such as the surface parameters and the orientation of the envelope, were analyzed by simulation. The results showed that when the thermal protection layer, thermal insulation layer, and gas barrier layer were respectively made of 20 mm Nextel BF-0,0 mm Pyrogel 6650, and 20 mm Kapton,the surface temperature of inner horizontal roof fluctuated between 16.8 ℃ to 22.4 ℃. In addition, the thickness and thermal conductivity were found to be the most important factors affecting the heat transfer performance of the building envelope. To balance construction costs and thermal insulation performance, the thickness and thermal conductivity of the building envelope should be reduced as much as possible by using low-density, high-specific-heat materials. It was also concluded that the convective heat transfer coefficient of the inner surface and the emissivity of the outer surface directly affected the boundary heat transfer of the envelope. Therefore, materials with differential thermal inertia and emissivity of the outer surface can be customized based on the radiation characteristics of different orientations and thermal comfort requirements. |
