What is the difference in performance between bag ducts made of different materials?
2024-10-07
There are the following differences in the performance of cloth bag air ducts made of different materials:
First, fiber material air duct
Ventilation performance:
Fiber material usually has good air permeability, can achieve uniform air supply, so that the flow of air in the duct is smoother, reduce the wind resistance, thus improving the ventilation efficiency.
Due to the pore structure of the fiber, it can adjust the air volume and air velocity to a certain extent, to adapt to different ventilation needs.
Thermal insulation performance:
Fiber material has good heat preservation performance, which can reduce the heat loss of air in the process of conveying, especially in winter or need to maintain a specific temperature of the environment, help to reduce energy consumption.
For some temperature-sensitive places, such as cold storage, constant temperature workshop, etc., fiber material bag duct can better maintain the stability of indoor temperature.
Fire performance:
Different kinds of fiber material fire performance varies greatly. Some specially treated fiber materials can achieve a certain level of fire protection, such as flame retardant fibers, which can prevent the spread of fire to a certain extent and improve the safety of the building.
However, ordinary fiber materials may be flammable and need to be evaluated according to the specific use environment and fire prevention requirements when choosing.
Antimicrobial properties:
Some fiber materials have certain antimicrobial properties, which can inhibit the growth of bacteria, mold and other microorganisms, which is an advantage for more demanding sanitary places, such as hospitals and food processing plants.
However, it should be noted that the antimicrobial properties may diminish with time of use and require regular cleaning and maintenance.
Strength and durability:
The strength of the fiber material is relatively low, and it is easily damaged by external forces, such as pulling and scraping. Care needs to be taken to avoid contact with sharp objects during installation and use to avoid damaging the duct.
However, some high-strength fiber materials, such as fiberglass, have better durability and can withstand certain pressure and tension.
Second, plastic material air duct
Ventilation performance:
Plastic duct surface is relatively smooth, wind resistance is relatively small, can ensure the smooth flow of air, improve ventilation efficiency.
Plastic duct can be customized according to the needs of the shape and size is more flexible, to meet the requirements of different ventilation system design.
Thermal insulation performance:
The heat preservation performance of ordinary plastic material is general, not as good as fiber material. However, the thermal insulation effect can be improved by adding thermal insulation materials to the outer layer of plastic duct.
For some places that do not require high thermal insulation, plastic duct can meet the basic ventilation needs.
Fire performance:
The fire resistance of plastic material depends on its type and additives. Some plastic materials have good fire retardant properties, which can prevent the spread of fire to a certain extent.
However, most plastics produce toxic gases when burning, posing a threat to personnel safety. Therefore, when choosing plastic ducts, you need to consider their fire resistance and the safety of combustion products.
Antimicrobial properties:
Plastic material itself generally does not have antimicrobial properties, but it can be improved by adding antimicrobial agents to improve its antimicrobial capacity.
For places with high hygiene requirements, it is necessary to choose plastic ducts with antimicrobial properties and to clean and disinfect them regularly.
Strength and durability:
Plastic material has high strength and durability, can withstand certain pressure and tension, and is not easy to be damaged.
Plastic air ducts also have the advantages of corrosion and abrasion resistance, and are suitable for a variety of harsh environmental conditions.

Analysis on the Application of New Energy in Air Conditioning
With the development of the world economy, people have higher and higher requirements for living comfort, which makes us more strict in controlling room temperature. In terms of living comfort, the main forms are heating and cooling. In the process of air conditioning, a large amount of energy will be consumed, and the supply of energy does not conform to the development strategy of sustainable development, Therefore, it is necessary to start the development and utilization of new energy. This paper introduces the role of air conditioning, applies the form of new energy to air conditioning, and analyzes the advantages of new energy in air conditioning through examples.

Difference between bag duct and traditional duct
Bag air duct is also known as cloth air duct and bag air duct. The air duct is made of special fibers, while the traditional air duct materials are metal and non-metal, such as galvanized steel plate, aluminum and aluminum alloy plate, rigid PVC plastic plate, etc. Due to different materials and design concepts, there are huge differences between air ducts and traditional air ducts. There are ten differences between the new air duct and the traditional air duct:
