GSHPS analysis of long-term operating characteristics

A long-term test to the heat pump system has been conducted for its operating characteristics,which has been running 8 years.The results show that the difference in the cooling and heating load,regardless of the soil total heat imbalance will lead to unstable GSHP operation.For the heat load is less than the cooling load,it can balance underground heat accumulation by increasing the cooling tower.Later we observe soil temperature recovery so that the ground source heat pump can be more long-term stable operation,and maintain a certain energy level.The results on the current GSHPS' optimization design and of setting standards have a certain significance and guidance.
