摘　　要：目的 :研究帐篷涂层隔热效果,改善帐篷系统"日照超温"效应。方法 :实验用帐篷样品为多腔室气柱支撑一体式结构,密闭空间由双层篷体构成。帐篷内部设置4个测量点,包括帐篷过滤器通风口处、帐篷内顶灯处(2个)及缓冲间门帘上部。测试时,将帐篷展开放置在夏季室外常温环境条件下,测试记录时间从上午8:00至下午17:00,用智能温度记录仪实时记录涂层帐篷与非涂层帐篷内部温度的变化情况,分析比较帐篷内4处温度记录仪测量的温度差异,在无明显差别(P>0.05)的情况下,根据数值趋势,采用方差分析对相关度进行分析。结果:涂层帐篷平均温度低于无涂层帐篷,涂层帐篷内温度降低效应明显,平均温度低,温度变化范围小,且中午和下午时间段涂层帐篷内温度低于环境温度,说明在阳光照射强度大的高温时间段,涂层帐篷有较好的降温效果。结论:帐篷系统应用隔热涂层可以明显改善太阳曝晒导致的帐篷"日照超温"现象,阻止热量向帐篷内部的传递,降低帐篷内部温度,提高应急防控帐篷或野战救护所热区环境适应性。Objective To explore the insulation effect of the coating so as to relieve the influence of solar overtemperature on the tent system. Methods The tent had an integrated structure with multi cavity and air column support, and the confined space was composed of the dual-layer tent body. There were 4 measuring points in the tent, of which, one was at the filter vent, two ones at the ceiling lamp and the remained one above the curtain in the buffer area. The tent was deployed in summer outdoor environment, four thermographs were used for real-time recording of internal temperature changes in the tents with or without coating, and the recording began at 8：00 am and stopped at 5：00 pm. Comparison proved there was no significant differences between the measured values by the four thermographs（P 0.05）, and correlation analysis was executed based on numerical trend and variance analysis. Results The coating tent had the internal temperature lower than that in the non-coating tent,which had low mean temperature and low temperature range. The internal temperature in the coating tent was lower than ambient temperature at noon and afternoon, which meant the coating tent could lower the temperature effectively even in the duration at high temperature. Conclusion Thermal insulation coating applied to the tent relieves the solar overtemperature effect effectively, and thus enhances the the tent′s thermal environment adaptability.
