1. Distributed thermal response tests New insights on U-pipe and Coaxial heat exchangers in groundwater-filled boreholesDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : U-pipe Borehole Heat Exchangers (BHE) are widely used today in ground source heating and cooling systems in spite of their less than optimal performance. This thesis provides a better understanding on the function of U-pipe BHEs and Investigates alternative methods to reduce the temperature difference between the circulating fluid and the borehole wall, including one thermosyphon and three different types of coaxial BHEs.
