Thermal evaluation of coaxial deep borehole heat exchangers
H Holmberg, J Acuña, E Næss, OK Sønju - Renewable energy, 2016 - Elsevier
This paper presents a performance study of deep borehole heat exchangers. The coaxial
borehole heat exchanger (BHE) has been selected because for the present conditions it has
a better performance than the conventional U-tube BHE. A numerical model has been
developed to study the coaxial BHE. The model predictions are compared to detailed
distributed temperature measurements obtained during a thermal response test. The model
is found to accurately predict the behavior of a coaxial BHE. The influence of the flow …
