Numerical and Annalytical Review on earth to air heat exchanger and Exergoeconomic Analysis

In recent years, especially the last three decades, many studies have been done on earth to air heat exchangers or air underground pipes worldwide by researchers and professors.In this article we have tried to work with the most important markets in the past three analytical, numerical and exergoeconomic and offering them all at once and researchers interested in the subject or those who want to be familiar with the exchangers. Appropriate references to specialized and more complete study, to be collected. Research in this field of activity and a change in attitude on energy consumption and consequently reduce pollutants, as well as saving the economy
