METHOD AND STRUCTURE FOR INSTALLATION GEOTHERMAL EXCHANGER IN GROUND WATER ZONE

摘要

A method and a structure for installing a geothermal exchanger in a ground water zone are provided to increase the heat exchange efficiency of the geothermal exchanger by using the thermal conduction and the thermal convection due to artificial flow of the underground water. A structure for installing a geothermal exchanger in a ground water zone includes a geothermal exchanger(2) and a heat pump(4). The geothermal exchanger is buried in a ground water zone(100) to collect ground heat. A heat transfer fluid is contained in the geothermal exchanger. The heat pump is connected to the geothermal exchanger and performs cooling and heating operations by moving the fluid having the ground heat to a desired place for heat exchange. A plurality of wells(12) discharge the underground water to the outside or return the discharged underground water to the ground water zone to generate flow of the underground water artificially. The wells are provided at the outer side of the geothermal exchanger. Protection layers including porous materials are provided at upper and lower portions of the geothermal exchanger.
