摘要
相变材料(PCM)是一种储能材料,具有高蓄热性能.在建筑领域中,相变材料可用于地板辐射供暖系统中,通过利用相变储能地板能够储存和释放大量的潜热,可以实现削减供热系统负荷峰值的目的,从而达到建筑节能的效果.本文对目前蓄热技术、相变地板辐射采暖技术进行了总结,并简述相变材料物化性、地板结构及封装定形技术对其热性能的影响.最后,对其未来的研究方向进行展望.
Abstract
Phase change materials(PCMs)is a type of thermal energy-storage materials with high latent heat-storage ca-pacity.In the field of construction,PCMs can be used in the radiant floor heating system.Through the use of phase-change energy-storage floor,a large amount of latent heat can be stored and released to reach the purpose of cutting down the peak load of the heating system,thus achieving a building energy-saving effect.This paper reviewed the current ther-mal storage technology and phase-change floor radiant heating technology and briefly discussed the influence of physical and chemical properties of PCMs,floor structure,and encapsulation and shape-stabilization technologies on its thermal performance.Finally,its future research direction was outlooked.
