为评价相变储能墙板应用于主动和被动式节能建筑的热工性能，根据相变储能材料的特性提出了相对时间滞后率、节能效率以及峰温差3个评价指标.在此基础上研制了节能评价装置，利用相变石膏板和绝热材料导热系数参比板(参比板)进行对比实验，对相变储能墙板应用于主动式和被动式节能建筑的节能效果及对室内热环境的影响进行了评价研究.结果表明，相变材料掺量为5％的相变石膏板由初始温度上升至人体舒适温度上限的平均时间比参比板滞后约8．5％，维持室内人体舒适温度所耗电能节约23％，峰值温度低0．9℃.相变储能材料的加入提高了主动式和被动式节能建筑的节能效率，改善了室内居住环境，具有较高的工程应用价值.
For the evaluation of phase change energy storage wallboard’s thermal performance both in active and passive energy-saving building,three indicators-relative time lag rate,energy efficiency and peak temperature difference were proposed according to the characteristics of the phase change material (PCM).On this basis, energy-saving evaluation device was developed,by which the phase change wallboard and reference wallboard were tested contrastively.The wallboard’s energy-saving performance in active and passive energy-saving build-ings and effect to indoor thermal environment were studied and evaluated.Results showed that the wallboard of 5% PCM’s temperature rose 8.5% slower from the initial temperature to the upper limit of human comfortable temperature than that of reference wallboard,saved 23% of electricity to keep indoor comfort temperature,and 0.9 ℃ lower in peak temperature.Adding of PCM improved the energy-saving efficiency of building and also im-proved indoor living environment which has a high value in engineering.
