Abstract :
The thermal inertia of the soil is a very influential parameter in the operation of an air-soil heat exchanger. In this work, we studied the thermal behavior of three different soils (moist sandy, dry silt clay and dry sandy) in order to determine which one has the greatest thermal inertia. For this, we used the conduction analysis of the comsol software. According to our results, the most thermally stable soil is the dry sandy soil. It is this latter which possesses the greatest thermal inertia. Thus, for a possible use of an air-soil heat exchanger in Sahelian zone, it would be preferable to choose a dry sandy soil as a priority.
