Abstract
Geothermal energy is part in various clean sources in the world. The geothermal energy resources originate from the ground and its temperature varies according to depth and its thermal properties. This paper presents a numerical simulation of the soil temperature variation in different thermal properties depending on the nature of the soil. three different Specific heat capacity and thermal conductivity are used in this this simulation and have applied in Adrar city. Three soils A, B and C, each soil has characteristics that are different from the others are presented. The results showed that the soil C is considered the best soil in terms of results in the southern desert region that can be applied to help in ventilation, cooling homes in summer (22°C) and natural heating in winter (31°C). A is considered to be a soil with high thermal insulation and its results can be used for agricultural irrigation applications in desert areas in the summer season because its temperature stabilizes at 26 °C. As an economic vision, it can use the soil B in depth of 3 m to reduce costs, based on the convergence of the results of soil C in this depth, but it's remain less effective
