摘要
竖直埋管地源热泵技术的重点和核心是地下埋管换热器。地下埋管换热器的设计包括 :换热器形式和回路形式的选择 ,地下换热器尺寸设计 ,水平间距及热短路 ,管材的选用和换热能力等。地下埋管换热器的施工主要包括 :钻孔 ,下管 ,注浆、回填和换热器的安装。
The ground heat exchange is the critical and core of the vertical buried ground source heat pump. Its design technique includes: choosing the type of the heat exchanger and the circuit, designing the size of the ground heat exchanger, horizontal distance and heat losing, choosing the pipe and the capability of changing heat. And the process of engineering includes commonly: drilling, downing the tube, grouting and backfill and installing the heat exchanger.
