Full scale 3D numerical analysis for rock-soil heat response test related techniques to ground-source heat pumps

With the testing data, establishes a full scale 3D numerical calculation model for rock-soil thermal response test, and verifies the model by testing. Studies several technical problems related to rock-soil heat response test, the results show that the results are basically consistent between the heat release test and heat removal test; deleting the value at initial time improves the results insignificantly; the recovery of temperature of the rock-soil surrounding buried pipe after stopping heating is mainly in the first two days.
