Experimental study on indoor thermal environment of industrial building spaces enclosed by fabric membranes

Nowadays with the development of science, many new technologies are being introduced to the fabric membrane material fields. Membrane structures have been widely used in industrial storage buildings to reduce the dust pollution from open storage depots. But the thermal environment of these buildings is poor due to its light weight and low thermal resistance. It is worth exploring appropriate measures to study this problem. Therefore, a monitoring platform was established in order to study the indoor thermal environment of the industrial storage building with membrane structure. The solar radiation heat model was established using MATLAB program based on the theory of thermal transfers. And studied the impact of the outdoor temperature and solar radiation intensity in the heat transfer characteristics of membrane material. The indoor air temperature distribution of the buildings was also analyzed. The results show that solar radiation has a significant effect on the surface temperature of the fabric membrane material. The solar radiation of different intensities incident on the surface of the fabric membrane causes its surface temperature to fluctuate rapidly and significantly. Without indoor heat source, the indoor thermal environment is mainly affected by the solar radiation heat exchange of the fabric material.
