The 425000 GJ geothermal barge new construction project in Linyi County, Yuncheng is located in Linyi, Shanxi Province. In response to the heating demand of the urban centralized heating source in Linyi County, the underground water indirect heat exchange heat pump technology is adopted. The underground water is extracted through geothermal wells for heat exchange and reinjection, achieving the non discharge of tail water and providing a clean and stable geothermal heat source guarantee for urban heating.

The project construction includes the drilling of 16 new geothermal wells, including 8 extraction wells and 8 reinjection wells, as well as the construction of an energy island and a heating pipeline network of 2509 meters. The heating capacity can cover approximately 1 million square meters of buildings. The inlet and outlet water temperature on the heat source side of the project is 45/25 ℃, with a flow rate of 764m ³/h; The inlet and outlet water temperature on the system side is 50.5/60.5 ℃, equipped with 3 heat pump units with a total heating capacity of 33121kW.

This project achieves efficient development and clean heating application of geothermal resources through "geothermal extraction+indirect heat exchange+heat pump heating+recharge utilization", while balancing heating stability, sustainable resource utilization, and environmental protection requirements. It demonstrates the technical capabilities of Land in county-level geothermal heating, energy island construction, and geothermal heat pump system application.
