Evaluation of the shallow geothermal energy in the Xuchang area

Shallow geothermal energy,which exists widely in shallow underground soil and groundwater,is a kind of low grade and renewable energy.In this paper,on the basis of line heat source theory,the vertical pipe-burying method of soil heat exchanger is used to obtain different thermo-physical parameters of the rock and soil layers.The shallow geothermal energy storage and available quantity are calculated.The results can also provide theoretical base and technical support for the popularization and de...
