[0074] The four corners on the other side of the air duct assembly are left vacant for fixing with the exposed air duct assembly connectors of the adjacent air duct assembly (for example, on its left side).

[0075] In a preferred embodiment, the square-structured air duct assembly is formed by four modular prefabricated air duct panels being fixedly connected via a third fixing member 1003 .

[0076] The modular prefabricated duct plate comprises a duct plate body 1011, and both side ends of the duct plate body 1011 are covered with edge connectors 1022. The edge connectors 1022 are U-shaped structures, and both side edges of the duct plate body 1011 along the length direction are inserted into the two edge connectors 1022 and fixedly connected by screws 1033.

[0077] The edge-wrapped connector 1022 is made of metal material, such as inert iron sheet.

[0078] In a preferred embodiment, the third fixing member 1003 is a screw.

[0079] When in use, the modular prefabricated air duct sheet is directly transported to the construction site, and then four modular prefabricated air duct sheets are assembled into a square structure, and the adjacent modular prefabricated air duct sheets are fixed from the connected corners by screws to form an air duct assembly 100. The screw connections are all provided with edge connectors to ensure the connection strength. Finally, the air duct assembly connectors 200 are installed at the four feet of the air duct assembly 100 to form an air duct module.

[0080] Modular prefabricated duct panels can be processed on an assembly line with high processing efficiency. They are small in size and can be stacked for transportation, which greatly reduces transportation costs compared to the traditional method of assembling square duct components through L-shaped corner connectors and then transporting them to the construction site.

The exposed portion of the air duct assembly connector of the air duct module is inserted into the adjacent air duct module, and is connected and fixed by a fourth fixing member on two side surfaces of the corner portion that is in contact with the adjacent air duct module.

[0083] In a preferred embodiment, the fourth fixing member is a screw.

[0084] In the air duct system provided by this embodiment, iron sheet connectors are only provided at four corners between adjacent air duct modules, which greatly reduces the amount of iron sheet used and the overall cost of the air duct system compared to the traditional arrangement of iron sheet flanges around the air duct assembly.

[0087] Furthermore, the outside of the connection between the air duct plates of two adjacent air duct modules, that is, the outer circumference of the air duct assembly where the air duct assembly connector is located, is covered with a sealing plate.

[0088] The sealing plate is connected to the air duct module through sealant to further enhance the sealing of the air duct system and prevent air leakage.

[0089] The sealing plate does not need to be too wide, it only needs to cover the diagonal sections of the two duct modules.

[0090] The sealing plate can be made of waste duct sheet material. When making duct components, the duct sheet material is cut into a set length, which always produces a certain amount of waste. The remaining duct sheet waste can be used as the sealing plate. Waste utilization is low-carbon, energy-saving, and environmentally friendly, reducing the overall cost of the duct system.
