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.
