Abstract
Directly utilization of low temperature geothermal enthalpy energy has been carried out in 24 space heating projects with other comprehensive utilization. Main technology includes : new type welll head installation, automatic control system both for surface space heating system and downhole measurements, corrosion control technology, air-conditioning system etc. Compare with the indirect utilization system, directly system can safe producing geothermal water 23%, economize on electricity 26% ,improve utilizable heat energy 20%, cut down manager 33%, increase temperature of supply hot water of 4-5 oC, increase temperature inside of the room of 2oC, reduce drain off temperature of 10oC.Directly utilization of low enthalpy geothermal energy has received good environmental and economical benefit.
