Study on Heat Transfer Capacity Calculation of Multi-Hole Heat Source for Vertical U-Tube Ground Heat Exchangers
By studying the features of vertical u-tube ground heat exchangers, with the consideration of the mutual interference between heat exchanger wells on heat transfer, this thesis puts forward the numerical model and calculation method for the heat exchange study of the well group, on the basis of analyzing heat exchange for single well. The paper adopts a nine-well model which is convenient and represents the general patterns of the heat exchange between well groups. The amount of the heat exchange between well groups can be calculated through testing the heat exchange of the single well by means of the heat exchange correction coefficient.
