CONSTRUCTION METHOD OF HEAT EXCHANGE EQUIPMENT OF GEOTHERMAL HEAT UTILIZATION SYSTEM AND GEOTHERMAL HEAT UTILIZATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a geothermal heat utilization system which is excellent in constructive performance and has preferable efficiency.SOLUTION: A geothermal heat utilization system (10) is configured by embedding a U-shaped pipe 12 underground as a heat exchange device. Therein, the U-shaped pipe 12 includes a curved joint 32 and two straight pipes 34, 36. Upon the construction of the U-shaped pipe 12, a curved joint 32 of one U-shaped pipe 12 is stacked on a curved joint 32 of the other U-shaped pipe 12 so as to leave a predetermined interval and such that respective curved directions cross orthogonally to be unitized and the unitized portion is arranged into a pit 104.
