【Abstract】 On the basis of the classic cylindrical heat source theory the operating performance model coupling the ground heat exchanger and heat pump performance is proposed. This model can be used in the short time step simulation of the long-term operation of the ground source heat pump system. The determination methods of some parameters in the simulation are discussed arid the operating performances in winter and in summer for given ground heat source pump system are simulated. Operating performance simulation results are validated by the test data from the ground source heat pump experimental system. It is shown that the model can predict the operating performance of the ground source heat pump accordant with the actual operating performance and can be used in ground source heat pump system design and operation control.更多还原
