Random Analysis on Line-Heat Source Temperature Field of Ground Source Heat Pumps Buried Pipes

In this paper the random properties of ground-source heat pump (GSHP) system. GSHP buried pipe to Kelvin one-dimensional line source of heat transfer model are discussed. The model randomness is analyzed, and the GSHP buried pipe to random excess temperature field, space-time statistics and the correlation of features are studied. The calculation results show that, heat transfer in buried pipe obviously have relationship with the distance from the pipe center and run time of system, and also the heat transfer between buried pipes can not be ignored. The method in this paper has great significance for improving the reliability design theory and reducing the construction cost of GSHP buried pipe.
