Review of soil temperature recovery characteristics of the GSHP system

摘要

Ground-source heat pumps (GSHPs) are receiving increasing interest because of their potential to be energy-saving and environment-friendly. The recovery of the soil temperature which ambient ground heat exchangers (GHE) is closely related to the stable and sustained operation of the GSHP system, thus a lot of investigations were carried out. This paper reviews the research made by different methods about the recovery of the soil temperature in and out china.
