Design and application of perforated damping plates in air duct systems;

Solutions of air duct condensation in engineering;

Discussion of criteria and software development for the optimisation of duct layout;

Review on the Application of Phenolic-aluminium Foil Compound Airduct;

Application of value engineering to cold and heat sources and duct scheme selection;

The production facilities and techniques for the rigid polyurethane foam panel faced with aluminum foil are introduced, and the manufacturing process of making wind pipe of central air conditioner from the panel is introduced too.

The structures of fibre glass reinforced plastic wind pipes, the selection of their wall thickness, and their application for ventilation engineering, are discussed, and the advantages of integral fibre glass reinforced plastic thermal insulation wind pipes, such as easy installation and good overall performance, are stressed.

CAD system for design and calculation of ship ventilation duct;

The sediment in the ventilation duct and air conditioning system can lead to a fire,and the existence of the duct is one of the major ways to spread the fire in the building.
