  The original design of fabric air duct has determined that the anti-condensation is a major function. The anti-condensation function is designed by making use of the permeability of the fibers in the duct wall to form a cool air layer on the surface of the duct wall, so that there is basically no temperature difference between the inside and outside of the duct wall, which can prevent the condensation (the greater the permeability of the material is, the smaller the temperature difference between the inside and outside of the material is, and the less likely it is to condense). At the same time, the hydrophobicity treatment of the fiber material surface further improves the surface anti-condensation effect. In addition, the fabric air duct can also prevent the condensation on building structures and suspended ceilings by simply adding jet holes on the fabric air duct to form an airflow protective layer on the building surface. Then let us learn about how to eliminate condensation...

  Air duct mainly refers to the ventilation duct of the central air-conditioning system. It is often neglected but an important part of the air-conditioning system. At present, there are mainly four kinds of air ducts.   1. Galvanized sheet steel plate air duct: It is one of the earliest used air ducts made of galvanized sheet steel plate and is suitable for the transport of general gas with small moisture content. This kind of air duct is easy to rust. It doesn't have insulation and noise elimination functions and takes a long production and installation cycle.   2. Inorganic glass-steel air duct: It is a new type of air duct made of glass fiber reinforced inorganic materials. This kind of air duct is incombustible, corrosion-resistant, heavy, hard but brittle, and easy to deform and crack under the influence of dead weight. In addition, it doesn't have insulation and noise elimination functions and takes a long production and installation cycle.   3. Composite fibe...

  In many high-end residence communities, central ventilation system will be installed, and especially the fabric air duct used in supermarkets is relatively common. You will find that the installation of fabric air duct used in supermarkets is simple, and it is beautiful, high-grade and light with simple transportation and installation as well as fast and uniform air-out, so it is widely used in many fields. Do you know the characteristics of the fabric air duct used in supermarkets? What should we pay attention to when we install the fabric air duct in shopping malls?   The  fabric air duct  used in supermarkets is also adopted in many large factories and enterprises as well as in the construction process of shopping plazas. There are numerous brands and a variety of models and specifications for us to choose from. Many fresh food supermarkets will use fabric air ducts. The cool air can filter through the fibers of the whole duct wall and a cool air layer will be f...

  At first, the galvanized steel air duct was used in the air conditioning duct, and then a new FRP air duct was introduced. At present, these two kinds of air conditioning ducts are called traditional air conditioning ducts. They usually adopt the structure of air conditioning duct + insulation layer and need to use separate thermal insulation materials. Therefore, the construction period is long, the production cost is high, the duct is large, the heat insulation performance is poor, the appearance is unaesthetic and the installation space needs to be reserved. In particular, the service life is generally within 10 years due to material corrosion and other problems. Compared with the rapid development of consumer demand, traditional air-conditioning ducts have lagged behind the pace of the times; therefore, the market share of traditional air conditioning ducts is smaller and smaller, and they are faced with the fate of being eliminated.   There are many differences between ...

  1. The first generation product of fabric air duct   The first generation product of fabric air duct emerged in the frozen food industry in the world and China in the 1950s and the 1960s, and it was made of ordinary cloth, which is also known as socks air duct.   Because of ingoring the fiber permeability, the product can not match with the draught fan, so the air supply effect is terrible. The occurrence of problems such as air suppress and fiber service life resulted in the gradual disappearance of socks air duct in the 1960s and 1970s.   2. The second generation product of fabric air duct   The second generation product of fabric air duct emerged in the 1980s and 1990s. The air duct is made of the material with a certain range of permeability which is not precisely comtrolled and a certain fireproof property. This generation product of fabric air duct quickly developed in Europe and the United States in all walks of life, and now most products of domestic s...

  Due to its own characteristics, fabric air duct is especially suitable for some large and high space without ceilings. Because the space is high and there is no ceiling, the fabric air duct can be installed and used conveniently, which has unique advantages that various traditional air duct products cannot compare with.   At the same time, the fabric air duct can be used in all kinds of large space with grid ceiling and local solid ceiling. These places have large space and high space height, so the fabric air duct can be designed in different shapes and installation methods according to the space height.   Finally, the fabric air duct can also be used in some places with solid ceiling and complex decoration. Due to the complicated decoration, the fabric air duct can only be installed under the ceiling. In order to match with the decoration, the shape of the air duct is generally semicircular, and the installation method is wall-attachment slide installation.   Wit...

  With the rapid development of social economy, many large factory buildings will be equipped with central air-conditioning. Among the parts, the fabric air duct is a flexible air distribution system made of special fibers. It is an air-out terminal system that can replace the traditional air supply duct, air valve, diffuser, insulation material, etc. Fiber air duct is popular in customers because of its fast air-out speed and obvious functions, characteristics and advantages. So what are the advantages of fabric air duct?   You will find that the construction installation of fabric air duct is simple and it does not need special processing equipment. The construction of fabric air duct is fast, which can save the installation time. In addition, the fabric air duct is quite energy-saving, and the coefficient of thermal conductivity of fabric air duct is much lower than that of galvanized iron air duct. What is more, the position of the mounting hole is very flexible, which can...

  With the in-depth study of the air supply principle of the fabric air duct system , the design method of fabric air duct becomes maturer and maturer, including the study and calculation of the on-way resistance inside the fabric air duct.   There are also pressure losses due to the frictional resistance and local resistance along the length direction of the fabric air duct system. Because the pressure loss is proportional to the wind speed, when the wind speed along the length direction becomes smaller and smaller, the resistance loss also decreases continuously. At the same time, there are also local resistance losses at the standard parts of the air duct and at the air outlets.   The main part is the straight duct in  fabric air duct system , and there are a few tee-junctions, elbows and reducings in the system. Generally, the on-way resistance loss is the main resistance loss form. The frictional on-way resistance of the air flow in the duct with the unchanged a...

  With the rapid development of economy, many public places, especially large shopping malls and commercial districts with a large flow of people, have higher and higher requirements for indoor environment. However, the noise of the city has brought a relatively big problem to our life. The fabric air duct has effectively solved the duct noise. Now let's analyze what effects the fabric air duct have.   In the whole office environment, we will find that the air distribution system is particularly important. The air distribution system that is made of fiber and can provide uniform air supply can be called cloth air duct, socks air duct, fabric air duct, fiber fabric air duct, etc. We find that the fabric air duct system  can effectively improve the indoor acoustic environment on occasions with a large flow of people.   Generally, which aspects does the  textile air duct   solve the duct noise problem from? It can be found that the noise source of the whole ce...
