This study has been performed to investigate the heat extraction characteristics from shallow geothermal resources using a coaxial heat exchanger. First, the computer simulation program for a coaxial heat exchanger has been checked by laboratory experiments. After inspecting the effectiveness of the present computer program, a numerical simulation for a real scale model has been conducted under the condition that the heat transfer mechanism in the stratum is heat conduction. Unsteady heat extraction characteristics are presented, and the effects of the tube material, inner diameter, and circulation modes on the heat extraction rate are discussed. From the computed results it was found that the heat extraction performance using a coaxial heat exchanger greatly depended on the factors mentioned above in the range of the parameters covered in this study.
