The calculation of duct area is as follows: 1. The formula for calculating duct area is: circular duct F=π× D × L, where F - the unfolded area of the circular duct (in m2); D-diameter of circular air duct; L - Length of the centerline of the pipeline. Calculate by multiplying the circumference of a rectangular duct by the length of the centerline of the duct. The calculation rule for the surface area of ventilation duct elbows is to extend the duct to the intersecting centerline.

　　2、三通：风管长度以中心线长度为准(主管与支管以其中心线交点划分)，包括弯头、三通、变径管、天圆地方等管件的长度，但不得包括部件所占长度。直径和周长按图示尺寸为准展开，咬口重叠部分已包括在定额内，不得另行增加。

　　2. Three way: The length of the air duct is based on the centerline length (the main and branch pipes are divided by the intersection of their centerlines), including the length of elbows, tees, reducers, and other fittings, but not including the length occupied by the components. The diameter and circumference shall be unfolded according to the dimensions shown in the diagram, and the overlapping part of the bite is already included in the quota and cannot be increased separately.

　　通风管道安装注意事项

　　Precautions for installation of ventilation ducts

　　1、风管和风机连接时，先要在进出风口加上一个软接头，而且它的断面尺寸要跟风机进出风口一样的，软管接头可以用帆布材料，而且它的长度为200以上，松紧度也是要合适才行。

　　1. When connecting the air duct and fan, a flexible joint should be added at the inlet and outlet, and its cross-sectional size should be the same as that of the fan inlet and outlet. The hose joint can be made of canvas material, and its length should be over 200 with appropriate tightness.

　　2、风道和除尘的设备在连接前，也是要等这个设备安装好后，实际上会对图纸预制及安装。

　　2. Before connecting the air duct and dust removal equipment, it is also necessary to wait for the equipment to be installed, and in fact, the drawings will be prefabricated and installed.

　　3、在安装风道进和出风口时，要在风道预制时对它开出洞，在将它装完后的风道定要连接紧密。

　　3. When installing the air inlet and outlet of the air duct, holes should be drilled during the prefabrication of the air duct, and the air duct after installation must be tightly connected.

　　4、输送含湿量比较大时，管道也是需要设坡度，低点处要根据排水管进行连接，注意安装中，风道底部不能出现一个纵向接缝，如果是接缝处一定要密封处理。

　　4. When conveying high moisture content, the pipeline also needs to have a slope, and the low point should be connected according to the drainage pipe. During installation, it is important not to have a longitudinal joint at the bottom of the air duct. If it is a joint, it must be sealed.

　　5、输送易燃的钢板风道，在连接处也是要安装上跨接线，并且还要连接静电接地网。

　　5. When transporting flammable steel plate air ducts, jumper wires should also be installed at the connection points, and static grounding grids should be connected.

　　6、当水平风道达到了4m以上时，那么安装人员就要提前到带绑上，脚手架也是在把它跳板固定好，宽度一定要符合规范才行，防止工具等物掉落砸伤人。

　　6. When the horizontal air duct reaches more than 4m, the installation personnel should tie up the safety belt in advance, and the scaffold should also fix its springboard. The width must comply with safety regulations to prevent tools and other objects from falling and injuring people.
