对国内外土壤源热泵地埋管换热器常用计算方法的对比进行了阐述,根据我国地源热泵系统工程技术规范(GB50366—2005)的地埋管换热器计算方法,对某实际工程在夏季工况下的地埋管长度进行了计算,并对计算中存在的几点问题进行了分析,就布置方式和地埋管的间距对地层热阻的影响得到了初步结论。
The paper expatiates the common used calculation method of ground-source heat pump's heat exchanger in home and abroad. And according to the calculation method of heat exchanger in China's ground-source heat pump systems engineering technical specification (GB50366-2005), the paper calculates the underground pipe length for a practical project in the summer conditions and analyzes a few existence points in the calculation, and gets some preliminary conclusions of the layout and pipe spacing impacted the stratum heat resistance.
