Calculates the average temperature of inlet and outlet water for the ground heat exchangers under different well spacing conditions for a ground-source heat pump project in Tianjin using the EED2.0 and the EHPD1.0 software respectively. Obtains that the ground heat exchanger system for this project can be designed with the arrangement of 240 wells in 6 rows and 40 columns, and the well spacing should not be less than 6 m. If possible, the well spacing can be extended to 7 m, in order to optimize the working conditions of ground heat exchanger system.
