French term or phrase: Géothermie (excepté sol-sol)
Hi all,

The context is a Press Pack for a boiler company and specifically "Pompes à chaleur". The 3 categories of the latter are:

- Aérothermie sur vecteur eau
- Aérothermie sur vecteur air (multi-split réversible)
- Géothermie (excepté sol-sol)

The first two are covered in another Proz post but I'm not sure about the last one.
"Geothermal heat pumps (except ground-ground)"? Not convinced.

I'd appreciate any help and hope I've provided enough context.
Thanks in advance.

Geothermal heat pumps (except direct expansion)

I just translated a document on geothermal heat pumps and had to look it up myself. It corresponds to direct expansion or direct exchange heat pumps (both abbreviated as DX, more g-hits for the first but both are used). In French they also talk about "détente directe" http://www.therminove.com/geothermie-limoges and http://www.encyclo-ecolo.com/Géothermie#Sol-sol. It's an older method that some installers no longer use. Here are some additional links, and also check out the wikipedia page which helps explain it: https://en.wikipedia.org/wiki/Direct_exchange_geothermal_hea... Hope that helps!
