双顶帐篷隔热效果的研究

Research on Thermal Insulation Effect of Double-roof Tent

帐篷在救灾过程中发挥了巨大的作用,但是内部热环境较差。为了改善居住条件,笔者设计并制作了双顶帐篷。在相同外部条件下,对双顶帐篷和普通单顶帐篷进行了对比测试,数据显示,相比普通单顶帐篷,双顶帐篷内部空气温度和顶部内表面温度有一定幅度的降低,具有明显的隔热效果,可以有效改善内部热环境。在此基础上,使用FLUENT软件对不同间层厚度的双顶帐篷内的空气温度进行了模拟计算,并对计算得出的帐篷顶部得热量和内表面温度进行了分析,在不影响安装简便性和稳定性的基础上,帐篷顶部间距取为0.2 m为较优选择。

Tents play an important role in the relief process,while the indoor thermal environment is bad. In this paper,in order to improve the living conditions, a double-roof tent was designed and produced. Under the same external conditions, the comparison tests were carried out for the ordinary single-roof tent and double-roof tent. The results indicated that the indoor air temperature and inner surface temperature in the double-roof tent were lower than those of the ordinary one, it had obvious thermal insulation effect, and therefore the indoor thermal environment was improved. Furthermore, the indoor air temperature in the double-roof tent with different inter-layer thicknesses were simulated with the software of FLUENT, also the heat gain and inner surface temperature of roof were studied. It was concluded that double-roof tent had better insulation effect when inter-layer thickness was 0. 2 m.
