　　各种通风管道设计制作安装依据材质、形状、周长或直径、板材厚度、接口形式，按设计图示以展开面积计算，不扣除检查孔、测定孔、送风口、吸风口等所占面积。

　　The design, production, and installation of various ventilation ducts are based on material, shape, perimeter or diameter, plate thickness, and interface form. They are calculated based on the unfolded area according to the design diagram, without deducting the area occupied by inspection holes, measuring holes, air supply outlets, suction outlets, etc.

　　风管长度一律以设计图示中心线长度为准，包括弯头、三通、变径管、天圆地方等管件的长度。

　　The length of the air duct shall be based on the centerline length shown in the design drawing, including the length of fittings such as elbows, tees, variable diameter pipes, and round pipes.

　　风管展开面积不包括风管、管口重叠部分面积。

　　The unfolded area of the air duct does not include the area of the overlapping parts of the air duct and pipe openings.

　　直径和周长按图注尺寸为准展开。

　　The diameter and perimeter shall be expanded according to the dimensions indicated in the drawing.

　　整个通风管道设计系统设计采用渐缩管均匀送风者，圆形风管按平均直径、矩形风管按平均周长计算，以为计量单位。

　　The entire ventilation duct design system adopts a uniform air supply system with tapered pipes, with circular ducts calculated based on average diameter and rectangular ducts calculated based on average circumference, measured in square meters.
