<p>PROBLEM TO BE SOLVED: To provide a geothermal heat pump which improves heat exchange efficiency and shortens the depth of a bore hole.SOLUTION: In order to generate natural convection in peripheral water 2 or an antifreeze solution 2 injected into a bore hole 1, stirred or minute air bubbles are introduced from a lower end of a heat exchanger for convection generation or the like. Therefore, the depth of the bore hole 1 is reduced and even if the number of bore holes 1 is decreased, heat exchange efficiency is improved, thereby improving performance of the heat pump.</p> |
