Ground heat exchanger

Abstract

The invention relates to a ground heat exchanger utilizing the geothermal energy of the ground, comprising pipe conduits and channels mounted within a support structure. According to the invention, a layer of air-permeable materials is formed on the virgin soil ( 1 ), horizontally and/or at a small inclination angle relative to the horizontal direction, creating a circulation channel ( 9 ) of the exchanger, the channel being confined by a support slab ( 14 ) with spacer elements ( 11 ) coupled with a construction net ( 8 ) seated onto a stabilizing net ( 7 ), the whole structure being covered by an insulating layer ( 19 ). Furthermore, the heat exchanger is equipped with a collector of the process air having an appropriate shape.
