I had a geoflex geothermal system installed at my dad's place, works great, except for the loop coolant pipes sweating. house is constant 22degC which is almost 72F, no issues there. House calls for a 3.5 ton unit but ended up with a 4.5 Ton because of some clerical errors.
I checked the in and out loop connections, both about 52deg F or 11C which means there is not a lot of load on the compressor, out side should get colder as it starts to work harder.
The loop pipes run 20 feet through the basement, then through an insulated cold storage room, then exit the house through the foundation. The cold storage room has all sides and ceiling insulated with r10 or so, designed to have the whole room ground temperature. (that part works)
the loop lines running through the cold room are sweating or condensing, whichever term you prefer, even though they are insulated. it is getting to the point where I noticed mold growing in the room.
This room is almost air tight, so once all the humidity in the room condensed and went down the drain, it should have been dry as wellm yet 2 months have gone by and there is still water dripping fromn the coolant lines. Not in the rest of the basemen though.
I'm at a loss, I have no idea where this much water could be coming from. there are no hidden connections, all pipes are insulated with a neopreme - wetsuit type insualtion that came with the unit and works in the rest of the basement, just not in the cold room. No leaks as system seems to hold pressure once initial leaks at manifold were eliminated.
There was no evidence of a wet basement before the project. Had one basement leak in the cold room during major downpour but that was taken care of.
