Medium-Deep Geothermal Resources Comprehensive Utilization
Our company Medium-Deep Geothermal Resources Comprehensive Utilization technology use submersible pumps to extract geothermal water to the surface, adopt direct heat exchange, heat pump multi-stage ways to extract energy in geothermal water then complete purpose of heating, geothermal spring pool bathing, planting and breeding etc. Geothermal tail water is recharge into underground through recharged well to ensure sustainable utilization of geothermal resources.
Geothermal Heating Utilization
Our company geothermal heating technology adopts ”get heat not get water” ways, use submersible pumps to extract geothermal water to heat exchange station and supply heating for buildings using the energy in geothermal water extracted by heat exchanger. At present, geothermal heating combine heat pump technology to multi-stage utilize the energy hide in geothermal water and finally make geothermal tail water temperature less then 5℃ to back underground to maximum increase single well heating scale and heating benefits.
According to geothermal resource temperature difference, cascade use heat energy in tail water to supply heating.
（1）42℃-65℃ geothermal water adopts plate type heat exchanger for heating supply.
（2）5℃-42℃ geothermal water adopts heat pump technology for heating supply.
（3）Below 5℃ geothermal tail water totally is recharged back to underground.
