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

[Sébastien THOMAS]

Dear Joke,

 

>From my point of view, you can use type31b. Energy equation solved in this
type is suitable for both water and air. Be careful while fixing soil
temperature, type 77 is able to help you.

 

Regards,

Dear trnsys-users,

 

I want to model a canadien well or also called air-to soil heat exchanger in
Trnsys with the purpose to know the energy demand of my building and to made
an economical analysis.

Is it correct that type31b or type 556 of the TESS library may be only used
for a water closed ground heat exchanger? And not when you are working with
air?

 

What type should I otherwise use for the modelling? I also read something
about type 460 of Transsolar?

 

Thanks in advance,
