What are the applications of bag air ducts in central air conditioning systems?1

The bag air duct can be heated and dissolved into granules, or the air duct can be degraded into raw materials by special degradation technology, and then reused. Traditional air-conditioning duct systems mostly use composite glass fiber/phenolic/polyurethane ducts, etc. These ducts will produce pollutants during production and use, such as: the adhesive of glass fiber sheets contains a certain amount (15%) of urine Formaldehyde resin will slowly decompose and release formaldehyde; during on-site processing, the glass fiber will pollute the air duct, causing the glass fiber to fly and affect health; the phenolic resin will not react completely during the production process, and it will react again in the heating air, resulting in the release of formaldehyde ; The flexible air duct polyurethane will overflow a large amount of ODS during the foaming process, which will cause great damage to the ozone layer, and will also produce cyanide gas during combustion. Therefore, if the air conditioning system is to be environmentally friendly, the selection of materials for the air conditioning duct system is also one of the key factors. As the most advanced production equipment and process technology in the industry, the cloth bag air duct has strict zero-error quality control and barcode traceability system to ensure the best material quality. The entire material volume and weight of the fiber cloth air duct is 1% of the traditional air duct, occupying There are few natural resources. The production of traditional air ducts such as steel, phenolic, etc. takes up a lot of natural resources. For example, in a 10,000-square-meter supermarket, the cloth bag air duct only uses a few cardboard boxes of fiber cloth. According to preliminary estimates, the carbon emission is only 1% of that of traditional air ducts. At the same time, the degradable fiber cloth is used, which is also clean and healthy during use. The bag air duct ventilation system has the characteristics of uniform and comfortable air supply, health and environmental protection, convenient installation, and easy cleaning and maintenance. Widely used in supermarkets, shopping malls, exhibitions, theaters and other commercial public 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 air duct can supply air evenly. Due to the unique air supply mode of the bag duct system, which combines the advantages of displacement ventilation and induced ventilation, the stratification of cold and heat is achieved at a certain height in the air-conditioned room. The fabric duct allows the cold and heat to be mixed and delivered to the work faster. face. According to actual calculations, the time for supermarkets using the bag air duct system to reach the design temperature in summer is 10-15 minutes faster than that using the traditional system. Effectively avoid unnecessary energy loss! Due to the unique air outlet mode of the cloth bag air duct system, the cloth bag air duct system has a special anti-condensation method and the ability to accurately supply air. When the cloth air duct system adopts a large temperature difference to supply air, the comfort of the personnel is ensured without adding heat preservation. Additional costs such as materials and large temperature difference air outlets can achieve the purpose of energy saving. When the bag air duct system cooperates with other parts 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.
