The biggest difference with domestic bag Soss duct duct bag is a bag Soss duct is in accordance with US AC167 (fabric air dispersion system) industry standard for production, design and installation. The design and production of domestic bag ducts are not in accordance with any industry standards. Â
The difference is divided into the following three aspects: 1. Material permeability Â
Reasonable and accurate permeability is the fundamental guarantee for air conditioning effects. In the case of different installation heights, different air volumes, wind pressures, and air outlet areas, combined with the best balance point for anti-condensation and energy saving, different permeability rates must be selected to ensure the air supply effect. Â Otherwise, the following consequences will occur: when the wind pressure of the fan is small, when the permeability is selected too small, the amount of permeate air may be too small, and condensation may occur; and when the wind pressure is too large, when the permeability is too large, it may result in At high altitude energy loss; pressure relief, the air duct can not drum up, jitter; at the same time will cause the fan to work overload and burn. Â
The bagouth duct has 10 standard penetration rates, which can also be customized according to engineering needs, and the permeability error rate is less than 5% . Â The domestic bag air duct generally has only 1-2 medium and large permeability materials, and is a range value, and does not emphasize the accuracy of the penetration rate. 2 , material fire resistance Â
In China, the fireproof performance of the duct material must meet the requirements of the national standard 8624-2012 - B-s1, d0, t0 level. In public places, the "flags for flame retardant products in public places" must also be provided in accordance with the requirements of the national mandatory regulations. certificate. Considering the need for repeated cleaning of the fiber fabric duct in use, the fire department proposed that the duct must pass the water resistance 50 times and then achieve the Class B fire performance to ensure that the fire hazard after cleaning is eliminated in the past 20 years of use. .  The bagoses duct is made of fabric woven from permanent flame-retardant fiber, which is no longer affected by water washing and affects the flame retardant performance. It is the only one in China's fiber fabric air distribution system industry that has been tested for combustion after 50 times of washing. B-s1, d0, t0 requirements and products that are tracked by third-party product fire quality. At the same time, the bag Soss duct is also the only product in the industry of China's fiber fabric air distribution system that can provide the certificate of “flame-proof product identification in public placesâ€. ;  Most of the domestic bag air ducts are made of flame-retardant soaking fabrics. Even in the case of self-feeding test, it is difficult to achieve B-s1, d0, t0 requirements before washing, and no one can meet the B -level requirements after washing (unless Is the test report fraud). 3 , design and manufacturing capabilities Â
The national large-scale airflow organization laboratory owned by the bag Soss duct combines with the engineering CFD computer simulation technology to ensure that the actual project air output effect is more accurate and reliable. Â
Most domestic bag air ducts only rely on the design experience of traditional air ducts to estimate the size, number and number of openings of the air ducts, often causing the failure of the entire air conditioning system. Â
The Bagsos duct has four world-wide automatic production lines with a total capacity of 3 million square meters and a finer quality standard. The world's most advanced multi-head laser processing center enables the precise processing of the Buicksos duct system. The quality has reached the international top level of technology. Â
Domestic bag air ducts are very small in scale, most of which are simple workshop-style production, using small general-purpose laser cutting equipment, and no one has obtained production certification qualification for air duct products. Â
The fiber fabric duct system is different from a single standardized mature product. It is a new product that has just been developed, and it is a comprehensive customized product of design and installation service. The use of control can bring users inexpensive, installation and Use a better return than traditional. On the contrary, it will lead to the effect of the entire air-conditioning project and fire safety hazards.
Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
