GROUND HEAT BALANCE IN GSHP
For its energy saving and environmental protection advantages, Ground Source Heat Pump (GSHP) system developed very quickly in china in recent years. From living buildings to office buildings, GSHP systems become lager and lager. But in most place, the energy which GSHP systems put into ground in summer and extract from ground in winter is not equal. Then the ground heat balance becomes a key factor for long term steady running of GSHP system. This article introduced probable ground temperature changes in different climate zones, analysed a actual project earth temperature change in one years, and presented a design method based on accurate ground source response test, uses assistant refrigeration or heating equipment to assume peak load, combines GSHP in a composite system, the same time keep a least distance between different geothermal heat exchanger (GHE), to assure a successful application of GSHP system in large scale building.
