Enhanced geothermy cold and hot geothermy punching and cascade heatpump system for making both cold water and steam using the enhanced geothermy cold and hot geothermy punching

摘要

The present invention provides a core cold and hot geothermal hole structure and a cascade heat pump system for producing cold water and steam at the same time, including the core cold and hot geothermal hole structure. The core cold and hot geothermal hole structure includes a core cold and hot geothermal hole, a core insertion pipe, and a bored unit insertion pipe. The core cold and hot geothermal hole structure enables operation of heating by using geothermal heat of a core unit and can change the operation to the operation of cooling.
