Numerical Study of An Air-soil Heat Exchanger Related to a Habitat Air Conditioning in Sahelian Zone: Determination of Temperature Surfaces and Heat Flows

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.
