Abstract
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.
