Re: [TRNSYS-users] Canadien well/ air-to soil heat exchanger

[David Bradley <bradley@tess-inc.com>]

Joke,
I would not recommend trying to use either Type31 or 556 if your 
working fluid is air because neither one of them is going to treat 
condensation properly. I have used Type460 on a number of occasions and 
once even got the chance to check results against measured data. The 
input parameter file is a bit complicated to set up the first time but I 
think the component gives good results.
Best,
david
