[APD] Re: Heat exchanger - was aluminum in the aquarium
"Just a thought, but if you need further temperature reduction
there is another possibility you might try. Depending on where
you are located geographically you may be able to get very good
cooling performance from some pipe buried outdoors maybe 6-12"
down. I tried this once here (outside Detroit, in Michigan) with
maybe 20 feet buried about 4-6" (one shovel depth :-) and was
able to get a few hundred watts of dissipation very nearly
continuously. ::snip:: It's very effective cooling in the
northern latitudes, probably wouldn't work so well if you were in
southern Texas :-) "
Hi Bill,
I'm in Austin and we used that very method to cool a 30,000
square foot branch bank building. We drilled -lots- of holes very
deep to get to the cool parts of the ground. It was a big lot, so
we had plenty of room to srpead out. In Texas we pay a premium on
electrical peak demand, so not having a chiller switch on makes a
big difference. Dunno how it would affect the core temp of the
earth if everyone did it. (Lame reference to the movie The Core.)
