Briefly describe the application of bag air duct in central air-conditioning system

The entire manufacturing and installation process of the bagged air duct is environmentally friendly. The important thing is that it will not produce dust, rust and toxic smells like some traditional products during operation and use. It is an environmentally friendly product and a product that represents the future development direction. Moreover, it is convenient to disassemble and assemble, and can be reused. The bagged air duct can also be regenerated, such as heating and dissolving the bagged air duct into pellets or using special degradation technology to degrade the air duct into raw materials for reuse. Traditional air-conditioning duct systems mostly use composite glass fiber/phenolic/polyurethane ducts, etc. These types of ducts will produce pollutants during production and use. For example, the binder of the glass fiber board contains a certain amount (15%) of urine. Aldehyde resin will slowly decompose to release formaldehyde; glass fiber will pollute the air duct during on-site processing, causing the glass fiber to fly and affect health; phenolic resin will react incompletely during the production process, and will react again during heating, causing the release of formaldehyde ; Flexible duct polyurethane will overflow a large amount of ODS during the foaming process, causing great damage to the ozone layer, and cyanide gas will also be generated during combustion. Therefore, if the air conditioning system is to be environmentally friendly, the material selection of the air conditioning duct system is also one of the pivotal factors. As an industry-innovative production equipment and process technology, cloth bag air ducts, strict zero-error quality control and barcode traceability system to ensure material quality, the entire material volume and weight of fiber cloth air ducts are 1% of traditional air ducts, occupying natural resources rare. The production of traditional air ducts such as steel and phenolic aldehydes takes up a lot of natural resources. For example, in a supermarket of 10,000 square meters, only a few cartons of fiber cloth are used for the bag duct. According to preliminary estimates, carbon emissions are only equivalent to 1% of traditional air ducts. At the same time, a degradable fiber cloth is used, which is also clean and healthy during use. The bag air duct ventilation system has the characteristics of average and quiet air supply, health and environmental protection, convenient installation, easy cleaning and maintenance. Widely used in supermarkets, shopping malls, exhibitions, theaters and other public trade places; various sports venues; various industrial plants; various food plants, etc. It is a flexible air distribution system made of special fibers, and the fiber bag duct can evenly supply air. It is an air delivery terminal system that replaces air ducts, dampers, diffusers, and thermal insulation materials. Because the unique air supply mode of the bag air duct system combines the advantages of displacement ventilation and induced ventilation, it realizes the layering of cold and heat at a certain height in the air-conditioned room, and the fabric air duct allows the cold and heat to be mixed and delivered to the working surface faster superior. According to actual calculations, the time for supermarkets with bagged air duct systems to reach the design temperature in summer is 10-15 minutes faster than those with traditional systems. Effectively avoid unnecessary energy loss! Because the unique air outlet mode of the bag air duct system determines that the bag air duct system has a special anti-condensation method and the ability to supply air. The air duct system uses a large temperature difference to supply air Time to ensure the comfort of the staff without the need to increase the additional cost of insulation materials and large temperature difference air outlet, so as to achieve the purpose of energy saving. When the bag air duct system cooperates with other departments of the central air conditioning system, there is no need to increase the air volume and air pressure of the unit, and even the air pressure will be reduced, which plays a role in energy saving.
