地源热泵井间距的选择探讨
Selection of well spacing for ground-source heat pumps
摘要：
分别采用EED2.0和EHPD1.0软件对天津某地源热泵项目不同井间距条件下地埋管换热器进出水平均温度进行了计算分析。得出该项目地埋管换热器系统可以按照240口井6行40列排列设计，井间距不应小于6 m，有条件的场所，可将间距扩大至7 m，以优化地埋管换热器系统的工作条件。

Abstract：
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.
