Abstract

Based on cylindrical source model, heat transfer process between the underground pipes and the soil was simulated. The feasibility of this simulating method was validated by comparing its results with the temperature data obtained from the existing ground source heat pump test platform. Thus this method was applied to simulate the year-round operation of the ground source heat pump, study the impact of its operation on underground thermal equilibrium and analyze the thermal recovery ability of the soil. The results show that the long-running of ground source heat pump system will lead to the underground heat accumulation phenomenon in Wuhan. There is a tendency for soil temperature to recover the initial temperature during the transition period. The rational use of temperature recovery capability by soil itself will contribute to solve the problem of soil heat accumulation, and benefit to regulate underground thermal equilibrium.
