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。 Taking a ground source heat pump project of a large multi-storey factory in Langfang City, Hebei Province as an example, the resource conditions and design scheme of the GSHP system with multi-storey tall buildings are analyzed in detail. It is pointed out that the hole spacing, depth and pipe length should be adjusted according to different geological conditions so as to ensure the thermal balance of the soil. When U-shaped (single U or double U) vertical borehole heat exchanger is selected, , Should also take into account the total area, the number of holes, hole spacing and depth and so on.
