Key points for installing central air conditioning ducts:

The allowable deviation of the angle between the three-way or four-way circular air ducts of central air conditioning should be less than 1 degree. The connection of each section of the air duct should be in a detachable form, and welded air ducts and spiral air ducts can be appropriately extended. The connection between the air duct and the flange must not have any holes.

Key points for installing central air conditioning refrigeration pipelines:

Central air conditioning refrigeration pipes passing through walls or floors should be equipped with steel sleeves, and welds should not be placed inside the sleeves. The steel sleeves should be level with the wall, floor, or floor bottom, but should be 20mm higher than the ground. The gap between the pipes and sleeves should be filled with insulation or other non combustible materials, and should not be used as a support for the pipes.

Key points for installing central air conditioning ventilation fans:

The inlet and outlet ducts of central air conditioning ventilation fans should have separate supports and be firmly connected to the foundation or other buildings. When connecting the ducts to the fans, the flange surface should not be pulled hard or forced, and the casing should not bear the weight of other components to prevent deformation. The exposed part of the transmission device of the ventilation fan should have a protective cover. When the air inlet or inlet pipeline of the ventilation fan is directly connected to the atmosphere, a protective net or other safety measures should be installed. If the base of the ventilation fan is placed directly on the foundation without a shock absorber, it should be leveled with paired diagonal pads.

Key points for installation and operation of central air conditioning air handling room:

The installation of the processing room is a very important part of the central air conditioning project. The assembly of each section of the metal air processing room and the sprinkler section must not leak water. The inspection door of the air spray section shall not leak water, the upstream pipe of the condensate shall be unobstructed, and the condensate rope water shall not overflow. The supply and return short pipes embedded in the brick and concrete air treatment room should be welded with square rib plates, and the pipe ends should be equipped with flanges or threaded ports. At the same time, the heat dissipation surface of the surface type or heat exchanger should be kept clean and intact.
