摘要
In order to maximize the economic benefit of ground source heat pump system, it is necessary to grasp the heat transfer rules of ground heat exchanger, the wedgelet finite element method is applied in analyzing heat transfer process of ground heat exchanger. First, existing researches on heat transfer analysis of ground heat exchanger and wavelet finite element method have been summarized. Second, the basic characteristics of wedgelet function are studied. Third, the wedgelet finite element model of analyzing heat transfer rules of ground heat exchanger is constructed using wedgelet function as interpolation function. Finally, the heat transfer simulation analysis of vertical U-type ground heat exchanger is carried out, and results show that the wedgelet finite element has higher precision and efficiency, and the effect of main affecting factors on heat transfer rules of ground heat exchanger is obtained.
