Efficiency Analysis of the Main Components of a Vertical Closed-Loop System in a Borehole Heat Exchanger
In vertical closed-loop systems, it is common to use single or double U-tube heat exchangers separated by longitudinal spacers. In addition, the helical-shaped pipe is another configuration that requires lower drilling lengths but it is less used. The aim of the present research is to study the infl...
