Abstract

Combined with the ground-source heat pump engineering in Hefei, a 100-meter-deep vertical u-shaped buried pipe was analyzed, and the experimental study on the heat transfer performance of different operating mode, the unit energy efficiency and the change of soil temperature field was taken under a typical climate condition in the summer of Hefei. The change of soil temperature field around the heat exchanger after running for a long time was simulated and analyzed. The results show that soil temperature increased by 1.2 ℃ after the system ran for 5 years .
