Assembly mechanism (internal insulation) finished air duct solution
The biggest difference between the inner insulation air duct and the outer insulation is that the insulation and the air duct are designed together to save the time of doing insulation separately. The construction period can be reduced. It is more suitable for engineering projects with high construction period requirements. It can effectively shorten the construction period and save time.
- The advantages of machine-made metal (internal insulation) metal finished products
1. High strength: strong galvanized steel plate provides effective protection for the thermal insulation layer; integrated molding, unique occlusal technology makes the air duct almost no air leakage (the test result is one-seventh of the national standard), the thermal insulation effect and aging are straight, so it can be widely used in various types of buildings.
2. Good sound absorption and noise reduction effect: The imported black glass fiber insulation cotton is attached to the inside of the air duct, which can effectively absorb all the sound generated or transmitted inside and outside the air duct system, and can completely replace the muffler. All are specially used in places that have certain requirements for acoustic environment, such as concert halls, conference rooms, exhibition halls, guild halls, hotels, cinemas, KTVs, etc.
3. High fire rating: Class A fire rating, effective flame retardant, especially suitable for super high-rise buildings.
4. Antibacterial and mildew proof, green and non-toxic: The imported black glass fiber thermal insulation cotton has excellent characteristics of anti-corrosion, anti-fungal and anti-mildew. At the same time, the adhesives used in the finished air ducts of machine-made metal (internal thermal insulation) are imported green Non-polluting water-soluble adhesive, high bonding strength, no benzene, no flame spread, washable and other characteristics.
5. Prefabrication processing: All air ducts are prefabricated in the factory. According to the processing list in the solution, reasonable planning, centralized procurement of raw materials, accurate data, integrated molding, and unified logistics can save procurement costs, control product quality, and facilitate multiple parties. Supervision, high product precision, convenient installation effect.
6. Assembly and construction: According to the installation drawings in the solution, each product has a detailed QR code for installation. The construction personnel only need to follow the prompts in the information to install the air duct accurately, conveniently and quickly. in place.
- Outstanding Features of Round Ducts:
1. Better sealing: the spiral bite will hardly produce air leakage, and compared with the rectangular air duct, the circular air duct has fewer connection points, which further reduces the possibility of air leakage and achieves better energy saving and thermal insulation effect. .
2. Better strength and rigidity: Compared with the rectangular shape, the circular shape has greater strength, stronger pressure resistance, further increased service life, and reduced maintenance costs.
3. Small ventilation resistance: the wind resistance of the circular air duct is smaller than that of the rectangular air duct, which has a better green energy-saving performance.
4. Easy installation: Compared with rectangular air ducts, the installation of circular air ducts is easier. The "Code for Construction and Acceptance of Ventilation and Air Conditioning Engineering" GB50243-2002 also points out that for rectangular air duct hangers with a long side size greater than 400mm The spacing is 4m, and the spacing of the spiral circular duct is extended to 5m.
5. Lower production cost: when the air duct is a small-diameter air duct, the difference is not big, but when the large-diameter air duct is used, the production cost of a round square duct is much lower than that of a rectangular air duct.
Based on the above advantages, it can be concluded that the assembled metal circular lined thermal insulation air duct is especially suitable for large-scale space projects, such as railway stations, airports, large shopping malls, subways, gymnasiums, exhibition halls, etc.

What is HVAC ductwork?
The term HVAC (heating, ventilation and air conditioning) ductwork describes any ductwork and vent system used to direct and distribute air in a vehicle or structure. HVAC ductwork is used in a variety of spaces from automobiles to homes to the largest construction sites, but all systems share certain characteristics in that they provide air circulation. Duct systems can be made from a variety of materials, depending on the intended installation site and the characteristics of the HVAC system it is designed to serve. All HVAC ductwork should be properly sized, tightly sealed, and securely installed for safe and efficient operation.
A simple residential HVAC ductwork consists of ducts that carry air from a central stove throughout the home. An additional ducting system is used to return air from one or more locations in the room to the furnace after it has passed through the filtration system. Air conditioning systems and humidity control systems are often part of this loop, especially in cold or dry climates.
Large structures employ HVAC duct systems that are similar in principle but larger in scale. Large central ducts carry air throughout the building and distribute it as needed through air vent diffuser. Filtration systems in larger structures are also larger, but serve the same basic purpose. Very large structures may use zoned or floor-separated heating and cooling systems.
HVAC ductwork can be constructed of many different materials. In its most basic form, piping systems are simple galvanized metal held together with screws or fittings. Ductwork can be insulated to minimise heat transfer and prevent condensation, a particular problem when ductwork carrying very cold air needs to pass through areas of warmer, more humid air. Plumbing is also available in vinyl and hybrid, which can be beneficial since vinyl components are less prone to rust and corrosion.
Large and small HVAC ductwork should be sized to fit the space they serve. A system with insufficient capacity will put additional pressure on the blower unit that circulates the air, while an oversized system will not provide adequate airflow because the blower cannot deliver enough air through the system to reach each diffuser. All HVAC ductwork should be properly sealed to maintain pressure in the ductwork and should be securely installed to minimize noise and vibration.
Ventilation ducts commonly used in HVAC systems
1.1 Galvanized iron air duct
At present, in the ventilation ducts of the more popular HVAC systems in our country, the phenomenon of using traditional construction procedures still exists. The air duct processed with galvanized iron sheet is only suitable for gas transportation with low humidity, because the galvanized iron sheet air duct is easy to rust and has no corrosion resistance. At the same time, it does not have the function of noise reduction and heat preservation, and it needs to add another insulation layer and protective layer, and also set up a muffler. In terms of production and installation, the cycle is long, and the service life is relatively short.
1.2 Inorganic glass fiber reinforced plastic air duct
The inorganic glass fiber reinforced plastic air duct based on magnesium oxychloride mainly uses glass fiber cloth as the material to undergo a certain chemical reaction with inorganic chemical raw materials to form a new type of product, which is widely used in the HVAC systems in working buildings. The size of the inorganic glass fiber reinforced plastic air duct should be made in strict accordance with the corresponding national standards. For products with special requirements, special processing and production can also be carried out. This kind of inorganic glass fiber reinforced plastic air duct has certain non-combustibility and corrosion resistance, but because of its relatively heavy quality and brittle hardness, it is more prone to breakage, deformation, and has no sound-absorbing performance, no heat preservation effect, and long installation period. Especially when it needs to be modified, the degree of loss is greater.
1.3 Composite glass fiber board air duct
The air duct is also known as the new super air duct, and the new super air duct has a huge change compared with the previous similar products. With the passage of time and the increase of successful practice cases, people gradually trust and affirm this super duct, and promote and apply it on a large scale. Super air duct is one of the most popular air ducts in recent years. Compared with inorganic glass and galvanized iron air duct, super duct not only saves space, but also prolongs the service life of air duct. The most important thing is that the investment cost of this air duct is relatively low, and it has a very high cost performance.
