As a high efficiency, low consumption and clean energy, ground source heat pump technology has been paid more and more attention. To calculate heat transfer performance between geothermal heat exchanger and rock and soil, heat transfer model is introduced. Non-steady-state heat transfer model of Vertical geothermal heat exchanger pipe are analyzed and discussed. By using virtual heat source and the Green function method, analytical solution of non-steady-state temperature field is given. Through comparative analysis, simplified formula is given for engineering applications. Based on the above analysis, further discussion is made, that imbalance of hot and cold load throughout the year do long-term performance effect to the heat exchanger. © 2011 Springer-Verlag.
