[TRNSYS-users] Geoexchange Field Design

[Fred Betz]

Is there a way of deciding a specific layout of the bore field using type 557a?
 
I have one vertical u-tube field type that is around the perimeter of a building, essentially all the pipes in a single row. 
 
The second is a typical vertical u-tube with the bore holes evenly spaced in an array. However that array is not symmetrical. 
 
Also, should I use a type 556 buried horizontal pipe between the bore field and the heat exchanger or a normal type 31 pipe? Is type556 meant to be used as a pipe or as another heat exchange method like type557a? Will the model take into account the volume of the pipe in the calculations so the simulation converges?
 
Thanks,
 
Fred
