Abstract:

Combining with projects of development and utilization of shallow geothermal resources that have been carried out, based on the collection and analysis of geology, hydrogeology and groundsource heat pump project information,  GSHP (ground source heat pump)monitoring systems including a groundwater GSHP monitoring station, a ground pipe GSHP monitoring station, as well as 20 GSHP monitoring points are set up. Through laying temperature sensors and data collection devices, we can realize dynamic monitoring, and adopt GPRS wireless transmission system to achieve longdistance transmission of monitoring data. Finally, according to analysis of monitoring data, the impact extents of the geological environment on the development and utilization of the shallow geothermal resources are assessed.It is concluded that the changes of soil temperature field are related to depth,and the changes of ground temperature are also associated with the system heat transfer power.

Key words: shallow geothermal resource, monitoring station, monitoring point, GSHP, temperature sensor, GPRS wireless transmission system
