建筑节能新技术——相变储能建筑材料

A New Building Energy Conservation Technique——Phase Change Thermal Storage Building Material

潜热储存具有较高的容积蓄热密度,在建筑节能、太阳能利用、余热回收和电力移峰填谷等领域具有重要价值。相变储能建筑材料是通过向传统建筑材料中加入相变材料制成的。相变材料具有较大的潜热储存能力。介绍了相变储能建筑材料的发展历史,研究方法和当前存在问题,以及目前值得深入研究的课题。

Latent heat storageis of great importance in building energy conservat ion,utilizing of solar energy, recovering of in-dustrial waste heat and off-pea k electricity since its high volume heat storage density.Phase change thermal s torage building mate-rials are madeby adding phase change materials .PCMs. to tr adi-tional building materials.PCMs are of great thermal storage ca-pacity.This p aper introduces the historyof PCM building materi-al,its studying methods,the existing problems and subjects de-serving to further investigate.
