| Abstract |
This paper uses in-situ thermal response tests to present the characteristics of the ground thermal conductivities of three different SCW GHX. These SCW GHXs were installed in the same site in Seojong City. The three different casesare distinguished by the flow direction and the presence of a filler. The first type (A) is constructed for water to flow downstream. The second (B) and third (C) types are designed for water to flow upstream, and a filler is additionally inserted into the third type. The results of the in-situ thermal response tests, indicate that the ground thermal conductivity for types (A), (B) and (C) are of 4.84 W/m?K, 3.40 W/m?K, and 11.62 W/m?K, respectively. |
