| Abstract: | To analyze deeply the heat transfer of the coaxial tubes underground heat exchanger, a new model to couple the fluid flow in the collecting tubes and the heat transfer between the tubes and the soil was proposed based on the existing equivalent model. The heat transfer characteristics and the performance of the coaxial tubes underground heat exchanger were analyzed by means of the numerical method. The effects of the sizes of the buried tubes on the outlet temperature of fluid in heat exchange and heat transfer rate were studied. |
