Influence of Convalescence on Soil Temperature Field of Well Group around Vertical Single-U-Tube Ground Source Heat Exchangers
In this paper,the mathematical physical model of the heat and moisture transfer in the single-U-tube heat exchanger of a ground source heat pump(GSHP) on well group is established and validated using observed data from the practical rock-soil thermal response test for a resident district in Taiyuan,water in soil is three-dimensional seepage flow and the soil is layered according to the geological structure in the depth direction.The dynamic load of the district for one year is input into the model.The temperature fields of well group are simulated numerically in the two conditions which convalescence periods are omitted or not.It shows that it rather necessary to take the influence of convalescence periods into consideration while predicting the soil temperature field of a GSHP system running for a long term.
