摘　　要：本文详细介绍了地热能高效换热技术,包括高效能源井的结构、建造方法,分析对比了高效能源井和U型地埋管的换热量,对高效能源井使用时的热干扰范围和恢复时间也进行了初步研究。地热能高效能源井(300m),同地埋管换热器(100m)相比,单井取热量增加9倍,释热量增加4.5倍,可大幅减少工程中的换热井数量和占地面积,为地热在建筑领域实现碳达峰、碳中和中担当重任,提供了可靠技术支撑,具有广阔的市场前景。In this paper,efficient heat exchange technology for geothermal energy is introduced in detail,including the structure and construction method of efficient energy wells,the heat exchange amount of the efficient energy well is compared with that of the U-shaped underground heat exchanger,and the thermal interference range and recovery time are also preliminarily studied for the efficient energy well.Compared with the underground heat exchanger(100m),a single efficient geothermal energy well(300m)increases heat gain by 9 times,and increases heat release by 4.5 times,as a result,the number of heat exchange wells and the areas they cover will be reduced sharply.
