摘要
Abstract
A numerical simulation model of square chilled beams with dual-layer cooling coils was devel-oped to investigate the effects of coil dimensions(di-ameter,horizontal pitch,and vertical spacing)on cool-ing capacity and induction ratio using Fluent software.The coil diameter has minimal impact on induction ra-tio,though increasing it from 10 mm to 20 mm reduces induced air outlet temperature by 1.50％and beam out-let temperature by 5.25％,while achieving maximum cooling capacity at 20 mm diameter(5.77％increase versus 10 mm diameter).Horizontal pitch expansion(30 mm to 70 mm)increases both outlet temperatures(4.82％and 5.72％respectively)with a 7.3％cooling capacity reduction,despite slight induction ratio im-provement.As the vertical spacing increases from 20 mm to 60 mm,the induced air outlet temperature first increases and then decreases,and the induction ratio first increases and then decreases.Optimal vertical spacing(40 mm)yields peak temperatures and induc-tion ratio,whereas 60 mm spacing produces the lowest values,with cooling capacity gradually decreasing throughout the spacing range.The simulation deter-mines that maximum cooling performance can be achieved with 20 mm coil diameter,30 mm horizontal pitch,and 40 mm vertical spacing under the studied conditions.关键词
