节能建筑用蓄热材料的释热性能实验研究朱华.pdf

, ( , 310027) : 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 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 : 节能建筑; 蓄热材料; 释热性能 : TK02 : A : 1004- 3950( 2006) 05- 0058- 03 E xperim en tal study on phase-change perform ance of therm al storage m aterials in the en ergy saving bu ildings ZH U H ua, CH EN G Yu-rong ( College ofM echanical an Energy Engineering, Zhejiang University, H angzhou 310027, China) A bstrac t: The phase-changem aterials play mi portant roles in solar energy system, energy saving bu il ings an heating or air con ition ing system s that absorb an release latent heat u ring the phase-change processes. A sort of therm al storage phase changem aterials, so ium sulfatem ixture was stu ie expermi en tally in this paper. The effects of ifferent thickening agen ts an nucleation agen ts on latent heat releasing perform ance of so ium sulfatem ixtu resw ere investiga- te . The results are valuab le to the stu y of energy saving bu il ing m aterials.
