摘要:
实验制备了高性能定形相变板材，基于该板材热物性参数搭建了装配式相变储能墙体模型，利用ANSYS软件模拟研究该墙体在郑州地区高温夏季的传热特性，对比该相变墙体与传统墙体内侧壁温变化和传热热负荷，分析了墙体的热阻、蓄热系数、热惰性指标，结果表明相变板材能显著提升墙体隔热性能，降低室内温度波动，能耗分析表明该墙体能节省居民空调用电。
Abstract:
Shape stabilized phase change materials board (PCMB)with high performance was prepared.Based on the tested thermal physical parameters of PCMB,phase change wall model was set up.Simulation analysis on the wall heat transfer characteristics in summer in Zhengzhou region was conducted by ANSYS software.Variation of indoor wall temperature and heat load in PCMB were compared with those of traditional wall.The wall thermal resistance,heat storage coefficient,thermal inertia index were analyzed.The results showed that the phase-change plate could significantly improve the thermal insulation performance of the wall,reduce the fluctuation of indoor temperature.Besides,the energy consumption analysis showed that the wall could save electricity for air conditioning.
