Abstract
A geothermal heating and cooling system is thermally coupleable to a ground coil formed from a thermal superconductor material. The system includes a heat intensification circuit, a thermal superconductor heat exchange coil and a thermal switch coupling the intensifying heat exchanger to the superconductor heat exchanger, and a thermostat controller connected to the thermal switch and intensifying heat exchanger. The system employs a high thermal transfer superconductor to efficiently move heat to and from the earth source for the purpose of heating and cooling. The system operates in cooling and heating modes by controlling the thermal switches and activating the heat intensification circuit in response to the difference between a set point and a measured temperature. Heat can be transferred to and from the superconductor heat exchange coil through various air and liquid exchange subsystems including fans, direct and indirect liquid heat exchange.
