Smart Otaniemi Borehole Model

In the project Smart Otaniemi, coaxial borehole heat exchanger concepts have been developed by utilizing dynamic modelling and building energy system operation optimization.

The website presents a simplified coaxial borehole model that is used to simulate steady-state heat transfer between the fluid circulating in a vertical borehole heat exchanger and the body of surrounding ground. The geometry for the studied borehole heat exchanger is shown in the figure below.

Settings: modify the input data and press Calculate to run the simulations.
Borehole summary: view the borehole dimensions and calculated key performance indicators.
Result table: compare and export the key results.
