摘要：PURPOSE: To provide a ground heat recovery device including a triple pipe,configured to efficiently exchange heat between fluid such as water flowing undergroundand ground heat for heat exchange with ground heat.CONSTITUTION: A ground heat
recovery device includes a triple pipe comprising: an outer pipe configured to take inground heat under the ground; a heat insulation pipe arranged on an inner wall surfaceside of the outer pipe so that ground heat from the outer pipe is transmitted; and aninner pipe that is arranged in the heat insulation pipe and whose bottom part or nearportion thereof is an opening part. The triple pipe is configured such that fluid subjectedto heat exchange with ground heat circulates in a clearance between the heat insulationpipe and the inner pipe, and between the outer pipe or a bottom part or its vicinity partof the heat insulation pipe, the inside of the inner pipe and ground load equipment. Theheat insulation pipe in the triple pipe includes a plurality of projection parts projecting inan inner pipe direction, on an inner wall surface of a portion opposite to or contactingwith a lower portion of the outer pipe.SELECTED DRAWING: Figure 1
