In the long-term, the efficiency and sustainability of deep borehole heat exchangers (DBHE) are always the focus of the industry. The thermal extraction rate, as well as the spacing between BHEs, are key parameters during the designing of such system. Supported by the NNSFC project Nr. 41628203, Junior Professor Shao and his team developed a numerical model based on the dual-continuum finite element approach. His presentation will introduce the basic mathematical principles of the newly developed code. Several modelling scenarios was constructed, representing the long-term operation of DBHEs and BHE arrays. Results will be presented with analysis on the heat extraction performance of such systems.
