摘要 ：介绍了竖直埋管地源热泵的国内外研究情况。理论研究主要是针对地埋管换热器进行模拟，准三维模型已经被广泛接受；实验研究相比理论研究要少一些，但也得出了一些指导性的结论；系统耦合利用和技术经济性的研究也有进展。目前我国的地源热泵应用处于起步阶段，但发展迅速，随着政府及群众的重视，这项技术将有广阔的发展空间。 关键词 ：竖直埋管 地源热泵系统 地埋管换热器 理论研究 实验研究 Progresses in research of vertical pipe ground?source heat pump systems By Yu Xin★, Wang Ruzhu and Zhai Xiaoqiang Abstract ：Presents the study status of the system. The theoretical study focuses on the simulation of ground heat exchangers and the quasi three?dimensional model has been popularly accepted. The experimental study is less carried out but still yields some instructive conclusions. The technical and economic study of the couple system also makes some progresses. Application of ground?source heat pump systems is still in primary stage in China, but it will be developed with growing recognition of the government and people.
