摘要：
Taking an office building in Changsha city, Hunan Province as the research object, its all-year hourly dynamic load is simulated by EnergyPlus software. On this basis, a simulation model of U-tube ground heat exchangers is built with the GSHP design software of GLD2012. The heat balance problem of the ground source heat pump (GHSP) system in long-term operation is discussed from influencing factors of soil thermophysical parameters and backfill materials' thermal conductivity. The simulation results are analyzed to show the reference to the optimal design of the U-tube ground heat exchanger system in engineering practice.
