Abstract:

Basing on the cylindrical heat transfer model of vertical ground source heat exchanger, and according to the mass conservation and energy conservation theorem, established a finite length cylindrical heat and moisture transfer model for soil layer around the borehole. Simulated the non-steady-state heat and moisture transfer of soil layers around the heat exchanger under summer operating conditions by using COMSOL multi-physics coupling analysis software, and analyzed the influence of different soil thermal properties and initial moisture contents in temperature field and moisture field of soil layers exerted by the heat and moisture transfer.
