厨房卫生间的排烟管道预留孔洞的尺寸在土建施工中确定方法：成品预制的矩形烟道，每层楼面的洞口边就是烟道的支座。只有圆形的薄壁透气管，可以支持在墙上的，如300mm内的，楼板留孔洞的尺放大30mm.
烟道就是指用于排除厨房炊事活动产生的烟气或卫生间浊气的管道制品，是住宅厨房、卫生间共用排气管道系统的主要组成部分。
运用原理
当进气口烟气排入烟道内时，会和下层往上排的烟气相遇，二股气流相遇会形成涡流和空气幕，该涡流和空气阻滞幕会对下层烟气上行产生阻碍，一旦防火止回阀被油污粘住开启失灵时，烟气因上行有阻碍，便会向室内串烟。

我是多年专业从事设计施工的工作人员。你所问的问题相对笼统，是指建筑设计还是装饰设计。如果是建筑设计，相对多层而言，自然习惯于两墙夹角处设计，自下而上。高层设计相对于质量方向要求更高些。至于如果是装饰上用，则排烟直接在离地面+2400mm以上排烟道上挖一直径等同于17CM左右的圆孔，将排烟管道固定在圆孔处即可。
