Abstract
Thermal resistance of steel energy screw piles
Highlights
The use of energy structures as underground heat exchangers in ground source heat pump (GSHP) systems is key for reducing the system’s capital costs (Lu & Narsilio, 2019)
The model was calibrated by simulating the Thermal Response Test (TRT) using the recorded heating power as an input and adjusting the soil thermal conductivity
The average fluid temperature over time obtained from the model was compared to the experimental results by calculating the resulting Root Mean Square Error (RMSE)
Summary
The use of energy structures as underground heat exchangers in ground source heat pump (GSHP) systems is key for reducing the system’s capital costs (Lu & Narsilio, 2019). The model was calibrated by simulating the TRT using the recorded heating power as an input and adjusting the soil thermal conductivity (λg). The average fluid temperature over time obtained from the model was compared to the experimental results by calculating the resulting Root Mean Square Error (RMSE).
