dc.description.abstract | In order to design coaxial-type Ground Heat Exchangers (GHEXs) efficiently, the effect of components (i.e, heat exchange pipe and grouting material) on the thermal performance of coaxial-type GHEXs should be identified in advance. In this paper, three coaxial-type GHEXs with different configurations were constructed in a test bed. Then, the effect of heat exchange pipes and grouting materials on the thermal performance of coaxial-type GHEXs was investigated by performing in-situ thermal response tests (TRTs) and thermal performance tests (TPTs). In the TRTs, the effective thermal conductivities of the coaxial-type GHEXs with concrete grouting and STS pipes were improved by 6.15 and 22.7%, respectively compared to those of bentonite grouting and HDPE pipes. Additionally, in the TPTs, the use of concrete grouting and STS pipes in the coaxial-type GHEXs enhanced the in-situ thermal performance by 15 and 33.8%, respectively. | - |
