摘要
储热材料性能优劣直接影响太阳能热发电系统的效率和成本,因此选择相变温度合适、储热密度大、传热速率高、经济易得并且环境友好的相变储热材料是太阳能热发电技术发展的关键。通过对相关文献的整理和分析,总结出相变储热材料的筛选原则,对最具发展潜力的高温熔盐和金属合金相变储热材料的研究发展现状、未来发展趋势进行了系统地总结和分析,并对部分相变储热材料的热物性参数进行总结,最后对相变储热材料选择的数学工具做了介绍,该文献综述研究对于今后太阳能集中热发电高温相变储热技术的开发和研究具有重要参考价值。
The performance of thermal energy storage materials will directly affect the efficiency and the costs of solar thermal power generation systems. Therefore, selecting a suitable phase change thermal energy storage material, which has appropriate melting temperature range, large thermal storage density and high heat transfer rate and is environmentally friendly, economical and easy to get, is the key of the development of solar power technology. Based on the collation and analysis of relevant literature, this paper summed up the selection principles of phase change thermal energy storage materials. Research and development status and future trends of the most potential high-temperature molten salt and metal alloy phase change thermal storage materials were systematically summarized and analyzed, and some of the materials＇ thermophysical properties were given. Finally, digital tools for phase change thermal energy storage material selection were introduced briefly. This literature review has important reference value for the future development and research on concentrating solar thermal power generation high-temperature phase change thermal storage technology.
