Identification et analyse des principaux facteurs influant le comportement thermique d’un échangeur air/sol enterré

Abstract

The thermal inertia of the soil allows it to maintain a stable temperature at certain depths, regardless of air temperature at the surface. We exploit this property by using a heat exchanger (air -soil) buried at depths appropriate, where a current of air passes through them for later use in air conditioning or heating. This work aims to study the factors that control the thermal behavior of these exchangers, where we first give a detailed definition of the latter, then we realized a mathematical model whose goal is to calculate the temperature for the soil any depth and any day of the year. And we made a numerical modeling to simulate the air temperature at the exit of the exchanger, for each day during the summer in the region of Biskra
