摘　　要：相变材料在发生相变的过程中吸收或者释放热量,在太阳能利用、建筑节能和空调采暖方面有着广阔的应用前景。通过实验研究了可用于节能建筑的相变材料———硫酸钠水合盐体系相变材料的释热性能,研究了不同增稠剂和成核剂对其放热性能的影响,对节能建筑用相变建材的研究有参考价值。The phase-change materials play important roles in solar energy system, energy saving buildings and heating or air conditioning systems that absorb and release latent heat during the phase-change processes, A sort of thermal storage phase change materials, sodium sulfate mixture was studied experimentally in this paper. The effects of different thickening agents and nucleation agents on latent heat releasing performance of sodium sulfate mixtures were investigated. The results are valuable to the study of energy saving building materials.
