Abstract

Geothermal heating system with horizontal wells doesn't extract ground water and is not affected by the distribution of geothermal resources, which is a closed-loop and environment-friendly system. In this paper, the heat exchange between the horizontal well and rock in the geothermal heating system with horizontal wells has been studied, the heat transfer model has been built, and the heat transfer at different flow rates of water has been calculated. The results show that the outlet temperature of the horizontal well increases with the decrease of the flow rate, and the flux of heat exchange decreases with the decrease of the flow rate. The outlet temperature and the flux of heat transfer have basically the same tendency with time. The three stages are respectively rapidly change stage, moderate change stage and linear change stage.
