Hello everybody,<br><br>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.<br>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.<br>
<br>Thanks a lot and sorry for my bad english<br>-- <br>Davillé Charlène<br><br>EPMI- Groupe ECAM<br>Université Pierre et Marie Curie<br><br>
