Abstract:
1. A geothermal exchanger system comprising: a first exchanger element comprising a return loop placed within a geothermal well, said first exchanger element is provided for circulating a refrigerant adapted to harvest heat from a ground surrounding said geothermal well by means of conduction and convection; a second exchanger element also placed within said geothermal well, said second exchanger element is formed from a material having thermal conductivity up to 150 w/m*k, said second exchanger element is also adapted to harvest heat from the ground surrounding said geothermal well by means of conduction and convection; said first exchanger element is totally encased within said second exchanger element, wherein said second exchanger element is placed in direct contact with the ground surrounding said geothermal well and wherein outer walls of said first exchanger element abut inner walls of said second exchanger element along an entire length of said second exchanger element, wherein said second exchanger element has configuration of a housing, wherein said housing is made of non-ferrous metal having thermal diffusivity up to 80 mm wherein said housing consists of a number of segments securely connected to each other by means of joint tubes and wherein each of those segments consists of two identical hollow halves securely connected to each other.
