By numerical simulation of finite difference, achieves the variation curve of entering and leaving temperature of cooling water and ground temperature field of GSHP system before and after coupled with ice thermal storage system. Obtains the performance characteristics and design points of GSHP coupled with ice thermal storagesystem. Keywords ground-source heat pump, soil heat exchange, model, ice thermal storage
