用于墙体中的固-固相变材料储热性能的研究

Research on the thermal storage performance of solid-solid phase-change material of wall

使用固-固相变材料作为墙体中的储能材料不会发生渗漏,能增加墙体的蓄热能力,减小室内温度波动,减少建筑能耗。通过实验研究了多元醇类相变材料组成的二元体系在不同组成下的储热性能,从材料的相变温度和相变潜热分析其应用于墙体中的可行性。研究结果表明:在一定的组成下,多元醇二元体系可达到墙体储能要求的相变温度,且相变潜热较大,是理想的墙体相变储能材料。

Solid-solid phase change material can increase the thermal storage ability of the wall,decrease the indoor temperature fluctuation and building energy consumption when it was used in the phase change material wall.This paper studied experimentally the phase change temperature and latent of polyalcohols binary system with different component,and analyzed the feasibility of phase change wall.The results show that binary systems have suitable phase change temperature and bigger phase change latent.They are ideal phase change materials used in the wall.
