An experimental study on the improvement of indoor thermal environment of tents by shading in summer

Because of the simple structure and easy to carry, tents are widely used in military camps, rescue and disaster relief, site construction, tourism, nomadic people living and so on. However, the tent is very hot and humid in summer which seriously affects people's rest and work. By the method of erecting a shading net on the top of the tent, the influence of solar radiation on the indoor thermal environment of tents in summer can be reduced. The indoor thermal environment of tents with different density shading nets was tested at a university campus of Tianjin, China. The experimental results showed that, comparing with the tent with no shading, the cooling effect of "six pins" net with shading rate of 96% is very good, the indoor temperature of the tent in summer can drop 8°C; while the indoor temperature of tent shaded by "three pins" net with shading rate of 75% can drop 5°C. The results also showed that: the internal surface temperature of the tent with shading nets can decrease about 12°C ∼17°C, the cooling effect is very obvious. The sun shading is conducive to improve the thermal environment of the tent.
