A mathematical model for simulation of ground source heat pump system is built based on line heat source theory. This model can be used in simulation of annual energy consumption of ground source heat pump system, and can be used to forecast the energy consumption of ground source heat pump system as well. The concept named as heat transfer cost is proposed for economic assessment of ground source heat pump system ; what＇s more, a calculation method of heat transfer cost is also deduced. The mathematical model of this paper can be used for designers of ground source heat pump to select a designing scheme that is more economical.
