This work will assess the performance of an horizontal air-ground heat exchangers (HAGHEs), varying the depth of burial and the air mass flow rate. The comparison will be done through simulations in the CFD code Fluent 6.3. Two depths of burial and four mass flow rates have been investigated, depth of 2.5 and 3.5 meters and mass flow rates of 150-250-350-450 m3/h, respectively. The analysis shows that there is no substantial difference changing depth, although a burial at a depth of 3.5 meters involves cost certainly more of a burial at a depth of 2.5 meters.

Abstract
This work will assess the performance of an horizontal air-ground heat exchangers (HAGHEs), varying the depth of burial and the air mass flow rate. The comparison will be done through simulations in the CFD code Fluent 6.3. Two depths of burial and four mass flow rates have been investigated, depth of 2.5 and 3.5 meters and mass flow rates of 150-250-350-450 m3/h, respectively. The analysis shows that there is no substantial difference changing depth, although a burial at a depth of 3.5 meters involves cost certainly more of a burial at a depth of 2.5 meters.File in questo prodotto:
