Evaluation of shallow geothermal clean energy in Zhumadian City
The development and utilization of shallow geothermal energy resources in the downtown area of Zhumadian City,Henan Province and the demonstration area for urban-rural integration first started in 2006,and has achieved relatively rapid development in recent years. This paper takes the shallow geothermal clean energy in Zhumadian City as an example of a comprehensive evaluation,and the study shows that:Zhumadian city centre and urban-rural integration demonstration area within the scope of the shallow geothermal clean energy resources are abundant,in the form of groundwater heat exchange and buried pipe heat pumps can be used in the form of resources of 14. 62 × 1012 kJ/a and 104. 39 × 1012 kJ/a,respectively,and the operation of two kinds of heat exchange system on the stratum of the temperature of the impact is very small. The results of this research can provide a basis for the scientific and reasonable development and utilization of geothermal clean energy in Zhumadian City,and it is suggested that the next step is to recommend the investigation and evaluation of the potential of geothermal resources in Zhumadian City,so as to improve the utilization efficiency.
