Hi sirs
We get a project for a ground source heat pump system. The HP is 240kw cooling capacity(7-12 C standard). We plan to drill 35 (120m)borehole to put double-U PE tube for underground heat exchanger . The borehole distance is designed for 5 meter each other. Now the place seems not enough for this ,may we can reduce the distance to 4m or less?
I really hope the experienced guy can teach me something about it. Thanks in advance.
regards
LC
