View Full Version : Geothermal ground loop-multiple source/sink

02-03-2006, 04:13 PM
I want to investigate an application for a customer. It would be a commercial application with a ground loop used for heat source and sink for multiple applications: space heat;space a/c; refrigeration (walkin cooler,walkin freezer), domestic hot water. Seattle area.

One ground loop. There is not much information about such an application..it would appear to be efficient if it could be balanced properly.

It can work perfectly, especially if you can recover heat from the walk-ins.
Try to condens as low as possible. Radiant hetaing if possible.
Ducts with grilles for the cooling
