Underground pile foundation heat exchange system with built-in capillary heat exchangers and construction method thereof
The invention discloses an underground pile foundation heat exchange system with built-in capillary heat exchangers and a construction method thereof. The heat exchange system comprises a plurality ofenergy piles, a cage-shaped capillary heat exchanger body is installed in each energy pile, and each cage-shaped capillary heat exchanger body is composed of a capillary water supply pipe, a capillary water return pipe and a plurality of capillary heat exchange pipes; the capillary water supply pipes and the capillary water return pipes are vertically and symmetrically arranged in the energy piles, the central axes of the capillary heat exchange pipes are arc-shaped, the plurality of capillary heat exchange pipes are installed on the capillary water supply pipes and the capillary water returnpipes side by side, so that each cage-shaped capillary heat exchanger body forms a cage-shaped structure, and the capillary heat exchange pipes are attached to the walls of the energy piles, an inletof each capillary heat exchange pipe is in direct communication with each capillary water supply pipe, and an outlet of each capillary heat exchange pipe is in direct communication with each capillary water return pipe. According to the underground pile foundation heat exchange system with the built-in capillary heat exchangers and the construction method thereof, and the problems that an existing ground source heat pump system is large in occupied area and high in initial investment when applied to urban energy demand intensive areas are solved.
本发明公开了一种内置毛细管换热器的地下桩基换热系统及其施工方法，换热系统包括若干能源桩，所述能源桩内安装笼状毛细管式换热器，所述笼状毛细管式换热器由毛细管供水管、毛细管回水管及若干毛细管换热管组成，毛细管供水管和毛细管回水管在能源桩内竖直对称设置，毛细管换热管的中轴线为弧形，若干毛细管换热管并列安装在毛细管供水管和毛细管回水管上，使笼状毛细管式换热器形成笼状结构，毛细管换热管贴合能源桩壁，每个毛细管换热管的进口与毛细管供水管直接连通，每个毛细管换热管的出口与毛细管回水管直接连通。本发明解决了目前土壤源热泵系统在城市能源需求密集区域应用中所面临的占地面积大、初投资高的问题。
