篷网织物网孔参数对篷内温变性能的影响

The effect of the mesh parameters of canopy mesh on temperature change properties

在帐篷外给帐篷"穿衣"可以调节帐篷内的热环境,以改善人在帐篷内的居住环境。经过测试多种织物的透气量、孔隙率、孔径大小,确定出在相关参数上具有同等梯度差的篷网织物;采用对比试验法研究篷网透气量和孔径分布两个参数对帐篷内温度变化的影响,以确定降温性能、保温性能优良的篷网织物所具有的结构参数。

For the purpose of improving the people＇s living conditions in tents, the thermal environment in the tent could be adjusted by putting clothes on the tent. After testing a variety of fabrics, and their quantity such as air permeability, porosity and pore size, the canopy mesh fabrics with the same gradient were determined for comparative test when the temperature changed. The effect of the quantity of air perme ability of canopy mesh and pore size distribution on the change of the temperature, inside the tent, was studied by comparative experiment. The structure parameters of canopy mesh fabric, having better properties for reducing temperature and heat retention, could be determined resoectivelv.
