Air-ground temperature difference utilization system and method

The invention provides an air-ground temperature difference utilization system and method, and relates to the field of new energy. The system comprises a convection channel, a temperature compensationstructure and an energy utilization device; the convection channel communicates with a geothermal source and a high-altitude low temperature area; the temperature compensation structure is connectedwith the convection channel; the energy utilization device is connected with an output end of the convection channel; and an insulation structure is arranged on the convection channel. The convectionchannel is built between the geothermal source and the high-altitude low temperature area; the temperature difference is used for converting geothermal energy to wind energy, so that the geothermal source is utilized more effectively; and meanwhile, as ground source heat and high-altitude cold are natural phenomenon, the system can be sustainable, and is lower in damage to the environment, wider application fields are achie
