| Abstract | Based on the heat and mass transfer theory in soil, an unsteady three-dimensional coupled heat and moisture transfer model for the U-vertical underground heat exchanger (UHE) in soil was set up in double cylinder coordinates. According to the model, analyses were presented about the influences of different soil properties, different operational modes, and different initial humidity on the temperature and moisture fields in soil around the UHE. |
