摘要
土壤储热技术是提高可再生能源利用效率的一种有效方式.从理论和应用二个方面对土壤高温储热技术研究现状与进展进行系统综述,总结当前存在的主要技术障碍和解决途径.总体而言,目前的土壤高温储热技术仍然处于起步阶段.在理论研究方面,揭示高温条件下土壤多物理场的耦合机理仍将是未来研究的主要方向,同时应关注与物理、材料、化工、仪器、计算机等学科交叉的研究,尤其是微尺度研究领域的技术进步.在工程应用方面,应注重系统运行能效、优化设计以及长期稳定性,同时还要考虑潜在的生态环境影响.
oil heat storage technology is one of major approaches to improving energy efficiency of renewable energy systems in the world.From the point of theoretical and applied research,this paper reviews the present status and latest advances of high temperature heat storage in soil,the key issues in the academic field,and some appropriate solutions.Results show that the present high temperature heat storage technology in soil is still in its early stage.Theoretically,it will still be a major task revealing the complex coupling mechanism of multi-physical fields in different soils,including temperature,moisture,salt and other chemicals.Close attention should be paid to interdisciplinary research including physics,material,chemical,computer and instrument science,and advances in micro-scale science deserve special attention.For the applied study,the further research direction of improving energy efficiency,optimal design and longterm reliability of heat storage systems are proposed.In addition,potential ecological and environmental effects should be taken into full consideration.
