Abstract   Usually,the annual absorbing and releasing load are always different in Ground-source heat pump running
which will lead to heat accumulation, and the heat pump  performance will degrade. Based on nature of shallow
geothermal resources and regional characteristic, the cause of ground heat imbalance in Ground-source heat pump is
analyzed. And heat imbalance    impacting on heat pump operation and the ecological environment are also analyzed.
Combined with the influencing factors of imbalance, the technical considerations for solving this problem is put
forward.
