Owing to effect of air permeability

thermal radiation adsorption and thin thickness

low thermal inertia and resistance of tent envelope become one fundamental reason causing poor indoor thermal environment of tent. For the sake of improving thermal performance of tent envelope

composite structure was proposed and applied in tent

including outer fabric layer

phase change material (PCM) layer and inner fabric layer. Meanwhile

the heat transfer model of this new type structure was established and verified. In addition

for the climatic conditions of Chengdu in China

the thermal performance of composite structure was evaluated and effectiveness of improving tent envelope thermal performance based on PCM was determined with the aid of numerical simulation under the influence of different PCM thermophysical properties

containing PCM thermal conductivity coefficient

latent heat

specific heat capacity and phase-transition temperature.
