Does pile length underestimate the rate of heat exchange?
As shown in Fig. 5 (a), for the case in unfavourable ground conditions, the computed results corresponding to the actual pile length of 30 m underestimated the daily-averaged rate of heat exchange by about 25% for both the modes of heat extraction and injection. To improve the situation, an equivalent pile length was calibrated.
