采光带不是越多越好，通风器也不是装得越高越管用——布置逻辑讲清楚。More daylight strips isn't better, and higher ventilators don't always work — here's the placement logic.
采光与通风是厂房舒适度的两件小事，但布置不当的后果很具体：光线刺眼、闷热、粉尘聚集。
采光带：面积建议占屋面的 8%–12%，过多会导致夏季辐射热激增。布置上避开正对工位的区域，优先设在柱间带；frp 采光板要选与彩钢板同寿命的抗老化等级，否则三年后先黄变漏水。
通风器：流线型屋脊通风器适合连续排风，涡轮通风器适合点式补充；热加工车间优先利用侧墙进风 + 屋脊排风的对流路径，比单纯靠风机省电得多。
这两个系统的开口都会切断檩条与钢板，必须在深化阶段预留，不能施工时随意开孔。
Daylighting and ventilation look like minor comforts, but poor placement has concrete costs: glare, overheating, dust accumulation.
Daylighting strips: aim for 8–12% of roof area — more means a radiation heat surge in summer. Avoid strips directly above workstations; prefer bay zones. FRP sheets must match the steel sheet's anti-UV class, otherwise they yellow and leak within three years.
Ventilators: streamlined ridge ventilators suit continuous exhaust; turbine vents are point supplements. Hot-process shops work best with wall intake plus ridge exhaust — natural convection beats running fans all day.
Remember: both systems cut purlins and sheets, so openings must be reserved at the detailing stage — never cut ad hoc on site.
