Abstract
Since 1995, researchers conducted studies about the performance issues of air-soil heat exchangers also called Canadian well. In this paper, we used Comsol software to study heat exchanges that take place in an air-soil heat exchanger intended for the air conditioning of a Sahelian zone house. The modeling was made with a complete 2D geometry. This study allowed us to determine the temperature surfaces, heat flow surfaces and values of the Peclet number. The results show that this system can contribute to the air conditioning in a Sahelian zone.
