Since both the cross-seasonal borehole thermal energy storage (BTES) system and the ground source heat pump (GSHP) system use buried tubes for heat exchange, GSHP is often mistaken for a BTES system. However, there are essential differences between the GSHP system and the BTES system, and the purpose of this study is to elucidate in detail the differences between these two systems. This study first summarizes the practical application cases of seasonal BTES globally, and then deeply compares and analyzes the differences between the seasonal BTES system and GSHP system from ten different perspectives, including system definition, technology timeline, purpose of buried tube heat exchanger, heat sources, soil temperature changes, buried tube heat exchanger volume, design of the buried tube heat exchanger, energy storage modes, biggest drawback, system performance evaluation. Finally, the future development prospects and research directions of the seasonal BTES system are further discussed. In summary, although the GSHP system may be confused with the seasonal BTES system in some aspects, they are indeed two different systems. Compared to the GSHP system, the seasonal BTES system can solve the contradiction between energy supply and demand in time and space, and effectively improve energy utilization efficiency.

季节性钻孔储热系统与地源热泵系统的十个区别


由于跨季节钻孔热能储存 （BTES） 系统和地源热泵 （GSHP） 系统都使用埋管进行热交换，因此 GSHP 经常被误认为是 BTES 系统。然而，GSHP 系统和 BTES 系统之间存在本质差异，本研究的目的是详细阐明这两个系统之间的差异。本文首先总结了全球季节性 BTES 的实际应用案例，然后从系统定义、技术时间表、埋管换热器用途、热源、土壤温度变化、埋管换热器体积、埋管换热器的设计、 储能模式，最大缺点，系统性能评估。最后，进一步讨论了季节 BTES 系统的未来发展前景和研究方向。综上所述，虽然 GSHP 系统在某些方面可能与季节性 BTES 系统相混淆，但它们确实是两个不同的系统。与GSHP系统相比，季节性BTES系统可以解决能源供需在时间和空间上的矛盾，有效提高能源利用效率。
