摘　　要：以冬季日照率较高、太阳辐射强度大的北京地区为研究对象,依据建筑热物理学、传热学以及相变贮能理论,结合计算机模拟分析以及实验的方法,研究了复合相变墙体材料在被动式太阳房中应用的可行性,为相变蓄热技术以及可再生能源在建筑节能中的应用提供参考.The passive solar house in Beijing area where solar energy resource is abundant in winter was taken to study. The properties such as long-time sunshine and intense solar radiation. Based on building thermal physics, heat transfer and phase change storage theories, the feasibility and energy conservation characteristic of the composite phase change material（PCM） wallboard in the passive solar house were studied by the methods of computer simulation and experimental analysis were studied, which provides useful reference for the application of heat storing technology of the PCM and the utilization of renewable energy in the building energy conservation.
