UNDERGROUND HEAT EXCHANGER AND GEOTHERMAL HEATING AND COOLING SYSTEM USING THE SAME

摘要

The present invention relates to an apparatus for exchanging underground heat and a geothermal heating and cooling system using the same, and the underground heat exchanger according to the present invention includes: a plurality of straight reinforcing bars 11 vertically buried in the ground; As a reinforcing bar, the plurality of straight reinforcing bars 11 are vertically wrapped from the outside to form a circle and are formed of a stirrup 12 coupled to the plurality of straight reinforcing bars 11 and soft, and the straight reinforcing bars 11 and the straw It is technically characterized in that it is arranged while spirally wrapped along the longitudinal direction of the straight reinforcing bar 11 from the outside of the coupling structure of the rub 12 and is composed of a heat exchange pipe 13 with both ends exposed to the ground.
