Title:
地中熱利用システム
Document Type and Number:
Japanese Patent JP7149376
Kind Code:
B2
Abstract:
To provide an underground heat utilization system that has reduced construction cost and can use geothermal heat by efficiently exchanging the heat.SOLUTION: An underground heat utilization system 1B includes: a cylindrical body 4 comprising multiple segments 2, which are connected to each other, and embedded in a stratum which has high underground heat; a heat exchanger formed inside a casing pipe mounted to the segments 2 to circulate a heating medium; and a water discharge channel or ventilation adit formed in an internal space 23 of the cylindrical body 4, thereby efficiently exchanging heat with a stratum which has high underground heat at low cost.SELECTED DRAWING: Figure 11
