摘　　要：将相变材料与建材基体复合,构筑成一种新型相变蓄能建筑维护结构。这种建筑维护结构可充分利用夜间低价电蓄热,供次日白天的辅助热源,降低采暖系统的投资与能耗,改善室内环境。主要探讨了相变材料与石膏等建筑基体复合后相变建筑维护结构的热特性。Phase Change Wallboard（PCW） is a kind of new energy-saving material which combined the phase change material with ordinary building material. This kind of PCW can make full use of the low valley electricity of nighttime and transforms it into thermal energy, then stores it as assistant heating resource next day. The PCW not only can reduce the investment of heating system and energy consumption, but also can improve the indoor environment. The thermal characteristics of some kinds of PCW are mainly discussed.
