Résumé
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 intemal 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.Concusion Thermal insulation coating applied to the tent relieves the solar overtemperature effect effectively,and thus enhances the the tent's thermal environment adaptability.
