| 摘 要： | 在比较地源热泵地埋管计算的2类线热源模型的基础上,本文采用有限长线热源模型与钻孔内热阻的准三维模型相结合的方式,在相应的建筑年逐时负荷条件下,进行地源热泵系统的逐时参数计算,通过与DST模型计算结果进行比较,验证了本文计算模型的准确性,为垂直U型地埋管的设计计算和热泵系统的运行模拟提供了必要的参考.

| Abstract: | In this paper,based on the comparison between infinite and finite line-source models,the relative hourly parameters corresponding to hourly building load were calculated by using the finite line-source model which was combined with the quasi-three-dimensional model of borehole resistance in ground source heat pump(GSHP) system.The accuracy of calculated results was validated by comparing with that of the duct storage system(DST) model.The presented model in this paper offered necessary references to design ... |
