摘要/Abstract

摘要： 为探究与制备更加适用于太阳能储能应用的四元相变材料,以Na₂HPO₄·12H₂O为主储热剂,Na₂SO₄·10H₂O,Na₂CO₃·10H₂O,Na₂S₂O₃·5H₂O与CH₃COONa·3H₂O为辅储热剂,在四种辅储热剂中任取三种与主储热剂按照设计的配比进行混合,制备四元相变储能材料,并选取纳米TiO₂,ZnO,Al₂O₃以及Na₂SiO₃和Na₂B₄O₇·10H₂O作为成核剂分别对其进行改性,通过步冷曲线、DSC、SEM、IR、XRD对样品进行数据分析。结果表明,Na₂HPO₄·12H₂O/Na₂CO₃·10H₂O/Na₂SO₄·10H₂O/Na₂S₂O₃·5H₂O为四元PCMs的最佳组合,其最佳配比(质量分数)分别为60%、10%、20%、10%(60/10/20/10)。在多种成核剂中掺加氧化锌的效果最好,当掺量10%(质量分数)时,四元PCMs的过冷度由3.0 ℃降低到0.2 ℃,相变焓由95.11 J/g升至472.39 J/g,相变温度区间从15.44~39.90 ℃改变至50.79~129.64 ℃,且无相分离。

关键词: 相变材料, 成核剂, 过冷度, 储能

Abstract: In order to make hydrated salt phase change materials more suitable for solar energy heat storage, Na₂HPO₄·12H₂O was used as the main heat storage agent, Na₂SO₄·10H₂O, Na₂CO₃·10H₂O, Na₂S₂O₃·5H₂O and CH₃COONa·3H₂O were used as auxiliary heat storage agents, and any three of the four auxiliary heat storage agents were mixed with the main heat storage agent according to the designed ratio, nano-TiO₂, ZnO, Al₂O₃, Na₂SiO₃ and Na₂B₄O₇·10H₂O were selected as nucleating agents to modify the quaternary phase change materials. The data of the samples were analyzed by step cooling curve, DSC, SEM, IR and XRD. The results show that Na₂HPO₄·12H₂O/Na₂CO₃·10H₂O/Na₂SO₄·10H₂O/Na₂S₂O₃·5H₂O is the best combination of PCMs,in which the optimal ratio (mass fraction) is 60%, 10%, 20%, 10% (60/10/20/10), respectively. Among the nucleating agents, zinc oxide has the best effect. When the content of zinc oxide is 10% (mass fraction), the supercooling degree of quaternary PCMs decreases from 3.0 ℃ to 0.2 ℃, the phase change enthalpy increases from 95.11 J/g to 472.39 J/g, the phase transition temperature ranges from 15.44 ℃ to 39.90 ℃ to 50.79 ℃ to 129.64 ℃, and there is no phase separation.

Key words: phase change material, nucleating agent, supercooling degree, energy storage
