number of U-tubes which maximizes the commercial and engineering benefits of multi U-tube applications, cost and performance … analyses of multi U-tube boreholes are crucial. In this study, a triple U-tube is used in a borehole of 50m depth. Time … predictions are made and compared for multi U-tube applications. Both experimental and computational results showed that …

This study is to evaluate the heating performance verification of ground source heat pump systems with U-tube and … commercial program to design various GLHEs. The U-tube and double tube GLHPs were installed in the same building, but each system … was in charge of different space air-conditioning. The performance of the double tube system was similar to that for the U-tube …
