Hello everybody,

I'm using the type 557 which models a tube in tube borehole. This exchanger extracts cold from the ground and transfers it into a building to provide space cooling all the year long.
I'm contacting you because i would like to know if this type takes in account the long term effect. I fact when you inject heat in the soil constantly the ground tempeture is suposed to rise. I don't understand why the Average ground temperature remains constant within the 5 years of simulation.

Thanks a lot and sorry for my bad english
