摘要
在对地层热量传递分析的基础上,通过相似理论建立地层储放能过程模拟实验系统,主要对不同储放能条件下,地层在储放能过程中的温度变化规律进行研究。研究表明:随着热源温度升高,在蓄热过程中地层温度的增幅变大;而在放热过程中,地层岩土温度的降幅减小。同时,地层在蓄热和放热过程中,地层温度沿水平方向的变化较剧烈,沿深度方向的变化趋缓。与实际地层储能技术的工程测量数据对比,地层储放能模拟实验可较好地反映在不同条件下地层的温度变化规律,为地层储能技术的工程应用和理论研究提供较精确的基础数据和参考。
Based on the analysis of heat transfer and similar theory, the energy storage/release experiment system of ground soil was fabricated. The temperature of ground soil was studied in different energy storage/release conditions. It indicated that the temperature increment is enhancive in the process of energy storage and the temperature decrease is reduced in the process of energy release with the temperature increment of heat source. Meanwhile, the temperature of soil changes acutely along level direction and changes slowly along the depth direction for the energy storage process and energy release process. Compared with the engineering application of underground energy storage, the experiment of underground energy storage can provide the temperature change rule of underground soil in the different conditions. It can provide the more accurate foundation data and reference for engineering application of underground energy storage.
