Abstract: Background/objectives: There exist many alternatives to store thermal energy for handling the seasonal offset. Among these alternatives, a borehole heat exchanger is better for storage of the thermal energy. Methods: In this work, the comparison of the performance of two boreholes U-tube models has been presented. The first one is double U buried pipes and the second one is single U buried pipes with a diameter of 25 mm and 32 mm, respectively. The performance is evaluated by the numerical method and analysis …
