Abstract：
Combining with a practical project, calculates the annual operation cost and heat balance of the buried pipes of the ground-source heat pump system with large temperature difference energy storage. The results show that the ground-source heat pump system with large temperature difference energy storage has the advantages of low operation cost, obvious energy saving and economic effect. The project adopts the integrated composite energy storage system of ice cool storage and water heat storage, which can realize energy storage in winter and summer, greatly improve the energy storage efficiency, save the operation cost of cold and heat source system, and reduce the space occupied by energy storage equipment.
