Dear Khaleel

It is very good to use the soil in space cooling but you need to dig more than 3 m below the surface.

Dear Dr. Miqdam  thank you for your observed  .  i want  the way and how .

Dear Khaleel

It is very useful methods but it depend on the area that you want to be cooling...also the economic value should be calculated

should know the effect of this method.. and calculate the environment and economic value

Dear Khaleel,  It will be good to keep it cool in in this case, but the adaptability of the soil to harsh climate should be also considered.

 Good Luck!

Dear all friend i thank you for answers . is putting a pipe buried in the soil to reject heat .

Soil is a good insulator but to cool a local climate plants, preferably trees, are better.

In order to use the soil as a thermal store you will need to know the thermal diffusivity (Dt)and heat capacity of the soil. Dt will change with water content and has a maximum below saturation and is low in dry and saturated soils.  The heat capacity is at a maximum at saturation and decreases as the soil dries due to water having a high heat capacity.  Depending on what the amount of heat is you need to dissipate you can calculate the surface area of the soil heat exchanger  that you need.  There are many models both analytical and numerical to do this.  You should consider what  the final temperatures are going to be at steady state.

One problem could be since the climate is hot the soil may be dry and hence the Dt may be low which will result in a very large area required to provide the necessary cooling.  You should also consider if there are alternatives as the cost benefit may not be sufficient to consider this option.

Interesting question , and some equally fine answer , enjoying reading this issue...
