Experimental Study on the Heat Transfer in Rock Layers with the Vertical Downhole Heat Exchanger

Abstract:

Through the in situ experiment of the ground-source heat pump (abbreviated as “GSHP”) system in Nanning Guangxi, this article has observed the temperature variation rules of the rock layers, by the temperature sensors buried in different depths and different locations from the Heat Exchanger. In addition, this article has also tried to explore the thermal environment of the rocks by analyzing the heat transfer of the soil layers acted under the thermal load in Southwest China regions where the ground water is abundant.
