【摘要】The energy pile is a kind of building energy-saving technology using shallow geothermal energy, and its heat exchange performance is an important factor affecting its development. In this study, heat exchange tests were carried out on three full-size cast-in place energy piles, and the influence of various factors on the heat exchange amount and the heat exchange rate was analyzed. The following conclusions are drawn:(1) the heat exchange rate of the cast-in place energy pile is greatly affected by the inlet water temperature;(2) increasing the pile length can increase the heat exchange amount, but has little effect on improving the heat exchange rate;(3) the increase in the heat exchange amount by heat exchange pipes in series is not significant, and therefore the parallel-type heat exchange pipes should be considered in practical engineering;(4) the appropriate circulating water flow velocity gives the best heat exchange efficiency.
