| Abstract: | Considering the complexity and diversity of subsurface rock soils,in-situ tests are necessary in determining the ground thermal property parameters.As an important basis of developing shallow geothermal energy,in-situ thermal conductive tests are crucial for the construction of ground source heat pump(GSHP) projects.Aiming at practical applications in the urban of Weifang,this paper describes the principle and method of conducting the in-situ thermal conductive tests,and obtains the local initial ground temperature,the ground thermal conductivity and the heat-transfer rate of ground heat exchangers.These test results can provide the designers some key data in order to optimize the GSHP projects based on the analysis of the building structure and air-conditioning load characteristics. |
