Abstract:
1. A superconductor geothermal exchange system having a plurality of thermal superconductors coupleable to at least one outside ground coil formed from a thermal superconductor material and extending below ground level to allow passive thermal conduction between an earth source and an above-ground thermal superconductor segment, the system comprising: (a) an intensifying heat exchanger comprising: (b) a heat exchange coil formed from thermal superconductor material, said heat exchange coil having a transfer segment comprising, at opposite ends, a first thermal superconductor exchange segment and a second thermal superconductor exchange segment; (c) a ground coil thermal switch thermally coupleable to said condenser and evaporator heat exchange segments and said above-ground thermal superconductor exchange segment, such that in a first switch position said above-ground thermal superconductor exchange segment is thermally coupled to said condenser heat exchange segment to operate in a cooling mode, and in a second switch position said above-ground thermal superconductor exchange segment is thermally coupled to said evaporator heat exchange segment to operate in a heating mode; (d) a heat exchange thermal switch thermally coupleable to said condenser and evaporator heat exchange segments and said second thermal superconductor exchange segment, such that in a first switch position said second thermal superconductor exchange segment is thermally coupled to said evaporator heat exchange segment to operate in a cooling mode, and in a second switch position said second thermal superconductor exchange segment is thermally coupled to said condenser heat exchange segment to operate in a heating mode; (e) a thermostat controller associated with an indoor space, said thermostat controller programmable with a desired set point temperature, said thermostat controller electrically connected to a thermal sensor for measuring said indoor space temperature, said thermostat controller electrically connected to said heat exchange thermal switch, said ground coil thermal switch and said compressor; whereby said ground coil thermal switch and said heat exchange thermal switch place the system in one of said heating and cooling modes, and said switch positions are selected in response to a calculated difference between said set point temperature and said measured temperature, said controller actuating said compressor in response to said calculated difference.
