摘要
Abstract
EnergyPlus is used to simulate the application effect of phase change material(PCM)wall.Take Foshan area as an example,the optimal phase change temperature and design thickness of PCM applied to building envelope is discussed and the influence of internal heat source on the simulation results of energy consumption is analyzed.The research results show that PCM with phase change temperature of 30℃has better energy-saving effect for the case studied.Considering the contribution of PCM per unit thickness to energy saving of air conditioning,the thickness of PCM layer should be 20 mm.Considering the internal heat source,the annual energy consumption can be reduced by 9.38%after PCM is set on the wall.关键词
