Unverified机箱风道搭配方案：前进后出+顶部出风形成正压差（进风数≥出风数）可减少内部积灰，进风口建议加防尘网；纯负压虽散热略好但缝隙易积灰82% similarUnverified机箱风道遵循正压差原则：进风扇总风量应略大于出风扇（如3进2出），形成正压可减少缝隙积灰；纯排气负压会从防尘网外缝隙吸入大量灰尘78% similarUnverified有风环境下效果大打折扣，风扇散发的美曲菌素会被吹散，最适合在无风或微风的静坐场景（如露台、庭院）使用77% similarUnverified带正压设计的新风系统可减少室外污染空气从门窗缝渗入，除霾效果优于负压/平衡式，但正压机对房屋密闭性要求高，老旧房屋缝隙多则正压效果打折75% similarUnverified充气结构在大风环境下容易被吹动或翻转，不适合无遮挡的强风场地单独平放使用75% similar
