竖直地埋管地源热泵系统在多层厂房中的应用
Application of vertical pipe ground-source heat pump to multi-storey factory buildings
摘要：
以河北省廊坊市某多层高大厂房地源热泵项目为例，详细分析了多层高大厂房应用地源热泵系统的资源条件和设计方案。指出应根据不同的地质条件调整孔间距、埋深和管长，以确保土壤的热平衡；在选用U形（单U形或双U形）竖直埋管换热器时，除考虑管长外，还应综合考虑总占地面积、钻孔数量、孔间距和埋深等。
Abstract：
Taking a ground-source heat pump system of a multi-storey factory building in Langfang City, Hebei Province as an object, analyses in detail the resource condition and design scheme for applying ground-source heat pump to multi-storey factory buildings. Points out that the bore spacing, buried depth and pipe length should be adjusted based on different geological conditions to keep the heat balance in soil, and that not only should the pipe length be considered, but the total occupied area, and the number, spacing and depth of boreholes when selecting U-type vertical pipe (single U pipe or double U pipe) heat exchangers.
