[EN] A borehole heat exchanger (BHE) is a ground heat exchanger devised for the extraction or injection of thermal energy from/into the ground. The knowledge of underground thermal properties is a prerequisite for its correct design. However, due to the differences of the underground thermal properties, sizes and configuration of BHEs, and backfill materials of boreholes, the thermal performance of BHE is site-specific. For this purpose, an in situ Thermal Response Test (TRT) is required to obtain the actual heat-transfer performance between the ground and the borehole heat exchanger, as well as the ground thermal properties, including the thermal conductivity, which is helpful for the design and optimization of Ground Source Heat Pumps (GSHP) system. Since from the 1990s, both the academic and commercial TRT cases have been increasing rapidly in European, American and Asian countries. Thereby, our objective is to analyse and design a TRT for the School of Civil Engineering of the University College of Dublin, according to their needs.
