Before the installation of the ventilation duct, check whether the size, elevation and the position of the calibrated supports and hangers of the air duct through the floor and wall holes meet the requirements. The spacing between hangers is 3m. For pipes less than 3m long, one hanger shall be set at both ends. In order to prevent the cold bridge from adding skids between the air duct and the hanger, the thickness of the skids is the same as that of the insulation layer.

垂直风管每层不少于一个支架，层高大于4m时支架不少于2个。

Each layer of vertical air duct shall have at least one support, and when the layer height is greater than 4m, there shall be at least two supports.

风管安装前，必须进行预组装和检查，才能按编制顺序安装到位。

Before the installation of air duct, pre-assembly and inspection must be carried out before it can be installed in place according to the preparation sequence.

在安装风道和零件之前，管道内外的灰尘和污垢，用聚乙烯薄膜密封两端，保持管道持管道内部清洁。包装好的风道及其部件安装前不得拆卸。

Before installing the air duct and parts, remove the dust and dirt inside and outside the pipe, seal both ends with polyethylene film, and keep the inside of the pipe clean. The packaged air duct and its components shall not be removed before installation.

风道支吊架应避免在墙洞或楼板上安装风口、风阀、法兰、检查门等部件的位置，支吊架与风道之间应设置垫木。

Air duct supports and hangers shall avoid the installation of air vents, air valves, flanges, inspection doors and other components on wall openings or floors. Pads shall be set between the supports and hangers and the air duct.

消声器安装的方向保证正确，且不得损坏和受潮。消声器单独设置支架，避免风管承重。

The muffler shall be installed in the correct direction without damage and damp. The muffler shall be provided with a separate support to avoid the load bearing of the air duct.

防火阀安装前，检查其型号和位置是否符合设计要求、有无产品合格证，防火阀易熔片要迎气流方向安装，为防止易熔片脱落，易熔片在系统安装后再装，安装后做动作试验，另外防火阀安装时单独设支架。

Before the installation of the fire damper, check whether its model and position meet the design requirements, and whether there is a product certificate. The fusible piece of the fire damper should be installed in the direction of the airflow. To prevent the fusible piece from falling off, the fusible piece should be reinstalled after the installation of the system, and the action test should be conducted after the installation. In addition, the fire damper should be installed with a separate support.

排烟阀、排烟口和手动控制装置（包括预埋导管）按设计要求安装。排烟阀安装后，进行动作试验，检查其手动操作、电动操作是否灵敏可靠，阀体是否紧密关闭。

Smoke exhaust valve, smoke outlet and manual control device (including embedded conduit) shall be installed according to design requirements. After the smoke exhaust valve is installed, conduct action test to check whether its manual operation and electric operation are sensitive and reliable, and whether the valve body is closed tightly.

对于进排风机，复合铝箔柔性玻璃纤维软管用于空调风管进出口与风管的连接，负压侧软管长度为l00mm，正压侧软管长度为150mm。

For the inlet and exhaust fans, the composite aluminum foil flexible glass fiber hose is used for the connection between the inlet and outlet of the air conditioning air duct and the air duct. The length of the hose on the negative pressure side is 100mm, and the length of the hose on the positive pressure side is 150mm.

安装风口时，确保风口与风管之间的严密、牢固连接；风口边框与建筑装饰表面紧密贴合；安装的风口表面确保其平整不变形，灵活调整。

When installing the air outlet, ensure the tight and firm connection between the air outlet and the air duct; The frame of the air outlet is closely connected with the architectural decoration surface; The surface of the installed air outlet shall be smooth and flexible.

安装过程中振动和噪音的预防振动和噪音的预防是安装过程中一个，安装过程中风管的振动和噪音的预防主要从以下几个方面着手：

The prevention of vibration and noise during installation is a key point in the installation process. The prevention of vibration and noise during installation mainly starts from the following aspects:

在空调机组中，安装连接在风机和风道上的软接头，以达到适当的松紧度，避免由于软接头过松而引起的噪音和振动，减少了进出风口的面积。

In the air conditioning unit, install the flexible joint connected to the fan and air duct to achieve proper tightness, avoid noise and vibration caused by loose flexible joint, and reduce the area of air inlet and outlet.

在每个系统风管的转弯处，与空调设备和风口的连接处固定支架，以防止风管振动。

Fix the support at the corner of each system air duct and the connection with the air conditioning equipment and the air outlet to prevent the air duct from vibration.
