Fabric membrane structure has a very good application prospect in the field of industrial material storage because it can effectively reduce the dust pollution of open storage yard. However, architectural fabrics material can neither store heat nor insulate. In addition, the high solar heat absorption coefficient and the spontaneous heat dissipation of coal lead to a poor indoor thermal environment. At present, there is still a lack of studies on the indoor thermal environment of industrial buildings enclosed by fabric membranes. In order to study the indoor thermal environment and natural ventilation of such buildings, field measurements and simulation calculation were carried out. The influence of outdoor air temperature and solar radiation on the indoor thermal environment was analyzed based on the measured data. Furthermore, in order to make full use of natural ventilation, a natural ventilation model was established by using computational fluid dynamics (CFD). The influences of different ventilation areas and air vents heights on the indoor thermal environment were analyzed, the corresponding optimization and improvement methods were proposed in this paper.

织物膜结构可以有效减少露天堆场的粉尘污染，在工业材料存储领域具有很好的应用前景。但是，建筑织物材料既不能储热也不能隔热。另外，高的太阳热吸收系数和煤的自发散热导致差的室内热环境。目前，仍然缺乏关于用织物膜封闭的工业建筑物的室内热环境的研究。为了研究此类建筑物的室内热环境和自然通风，进行了现场测量和模拟计算。根据实测数据分析了室外气温和太阳辐射对室内热环境的影响。此外，为了充分利用自然通风，利用计算流体力学（CFD）建立了自然通风模型。分析了不同通风区域和通风口高度对室内热环境的影响，提出了相应的优化和改进方法。
