Cloth air duct is often used in gymnasiums, breeding factories, warehouses, workshops, exhibition halls, and other occasions. It integrates noise reduction, static pressure, ventilation, energy-saving and other functions. In its development, cloth air duct has replaced the traditional iron sheet air duct in many places year by year.
Functions of cloth air duct:
1. Indoor air supply: This is the main function of cloth ductwork, which is mainly used as the outlet duct of indoor ventilation. And there are various ways of ventilation.
2. Energy-saving air supply: The optional air supply mode determines that its energy-saving nature will be very good. Different air supply modes for corresponding scenes can make the cloth air duct more energy-saving.
Air supply mode of fabric cloth air duct:
1. Permeable air outlet: The air outlet range is 0-1.5m, and wind speed can be slower than 0.2m/s.
2. Microporous air outlet: The air outlet range is 0-3m, and the end wind speed is about 0.2-0.5m/s.
3. Small hole ventilation: The range of ventilation is 3-15m, and the end wind speed is about 0.5-1.5m/s.
4. Nozzle air outlet: The air outlet range is 10-30m, and the end wind speed is about 0.2-1.0m/s.
The air supply of cloth air duct is multiple and can be combined with each other. Infiltration + opening air is a common way of air supply, which can be applied to common ventilation requirements. This way of air supply can be more flexible. Durkee currently supplies URR cloth ductwork, which presents more stable inner air velocity and more balanced inner pressure. Specifically, as for which way of air supply should be used for space you want to install, you can consult us about it.

Many railway stations, shopping malls, and other places are with the dense flow of people and poor air quality, so they will install air duct system. During the installation of air conditioning fresh air system, they will use cloth ductwork, which has obvious material characteristics, fast air output speed, light volume and weight of the whole material, it also can be installed easily. Therefore, it is widely used. So, what are the advantages of cloth ductwork?
The characteristics of the cloth duct are quite obvious, the airflow rate is very fast, the appearance is beautiful, and it can also be designed with the decoration. No matter it is the modern house decoration style, European style, or the Chinese style, it will use the cloth ductwork. The environmental protection aspect of the cloth ductwork is preliminarily tested and evaluated by the technical personnel. The carbon emission is only 1% of the traditional ductwork with even airflow and speed.
A lot of outdoor air is not circulating. If we want to achieve ventilation, we prefer cloth ductwork whose product quality is reliable. This kind of cloth ductwork is also very simple to install. Moreover, the performance advantage of cloth ductwork is more obvious. It is made of flexible materials, which will shrink when there is no air supply, greatly saving the installation space. In order to get a better visual effect, you can choose a double row suspension to install the system.
What are the characteristics and advantages of the cloth ductwork? Do you have a clear idea? During the construction of many houses, the flexible materials will shrink when there is no air supply, which greatly saves the installation space. Moreover, the cloth ductwork has strong plasticity. It can be arranged in an arc or a circle or an ellipse closed layout according to the actual needs. Moreover, the cloth ductwork has a large air outlet area, a large air volume, and an arc design, which is not only beautiful but also makes the air outlet more uniform, Therefore, it is welcomed by many customers.

In the last century, in the frozen food industry, to meet the special requirements of large cooling capacity and low wind speed in the refrigeration area, HVAC engineers from various countries tried to make the air supply outlet with ordinary cotton fiber fabric, which is in the shape of a cloth bag.
In the 1950s and 1960s in China, there were many cases of installing fiber fabric air duct insulation in the refrigeration industry, referred to as fiber fabric bag air duct for short. In some conditions, with the continuous innovation of fiber material technology and textile technology in the world, more and more fibers with special properties are made into the air distribution system, which makes the application field of the air distribution system of fiber fabric expand constantly.
Since the application of the cloth air duct in the food workshop, the cloth air duct system has developed for several decades, and the materials of the cloth air duct are more and more abundant. As an important part of the development of the world’s HVAC industry, the cloth air duct industry, based on economic and target market demand, keeps innovating and creates a leap of the cloth air duct industry with strong development momentum.
In the cloth air duct industry, the old type is made of common cloth, which can not be compared with the cloth air duct products made of high-performance fiber materials in permeability and use in all aspects. For example, the cloth air duct system is designed to produce air through the fiber gap of the whole pipe wall or through the designed multi-row small holes, that is, to supply air in a linear way along the pipe longitude, and in a fan way along the axial direction, providing three-dimensional air supply. The utility model has excellent comfort, uniform air supply, and accurate air supply and functions that other materials, such as fire prevention, do not have.
Cold chain logistics generally refers to frozen food that is always under the specified low-temperature environment in the process of production, storage, transportation, sales, and all links before consumption to ensure food quality and reduce food loss. Generally speaking, cold chain logistics is to transport products from the refrigerated warehouses of production and processing enterprises to the refrigerated warehouses of sales enterprises through refrigerated transport vehicles. It can be seen that the importance of cold storage in the cold chain system. The storage temperature of refrigerators is generally between – 15 ℃ and – 10 ℃, and there are many kinds of frozen products. Generally, it can be divided into meat food, agricultural and sideline products, fruits and vegetables, medicines, and special commodities. So, what are the problems that refrigeration facing?
1) Most of the refrigeration equipment with coil and cooling fan, which caused uneven temperature and humidity distribution, the high energy consumption of annual operation;
2) The objects of freezing and cold storage are perishable fresh food which has strict requirements of temperature and humidity.
3) There should be reasonable cooling mode and air distribution in the warehouse. For example, cold and fresh meat food, fruits and vegetables, not only require low temperature but also can not cause water loss. It can not have larger airflow for avoiding the air-drying phenomenon.
4) High requirements for health and safety in cold storage
Application advantages of a fabric air duct for fruit and vegetable cold storage:
The fabric air duct adopts the mode of infiltration and air out, with 360 ° air supply on the surface, and it is sent to the warehouse with a weak wind speed of less than 0.2m/s, so as to ensure that the indoor temperature distribution is even and there is no sense of blowing, which not only avoids the loss of water but also fully ensures the constant temperature of the warehouse, ensures the product quality, greatly saves energy consumption.
The fabric air duct system can ensure a stable temperature and humidity environment. On the permeable air distributor, the air diffuser through the whole surface of the air distributor. The air velocity is very low and evenly distributed, and the temperature gradient is within 0.5 ℃. When the traditional coil and cold air mechanism are cold, the temperature distribution in the warehouse is uneven, and the gradient often exceeds 2 ℃. The high-temperature gradient leads to product quality can not be guaranteed.
The air distributor of fiber fabric has good sanitary conditions, excellent permanent flame retardant performance, with no condensation water, avoids the breeding of bacteria and mold.
It is very convenient to clean the fabric air duct. Just open the zipper, disassemble it, and put it into the industrial washing machine for cleaning.
How to choose a profile for different fabric air duct has technical concerns. In general, the air duct can be divided into normal pressure state and negative pressure state. Under normal pressure, the common section shapes are circle, semicircle, 1 / 4 circle, bow, and sector, while under negative pressure, triangle and rectangle are commonly used.
Profile introduction under atmospheric pressure:
1. Circular, if there are not too many requirements for an appearance with space height allows, we suggest to choose this kind of air outlet profile. The air outlet area is larger, and the air output is more, so it is more time to change the indoor air.
2. Semicircle, if the height is not allowed or it can be used in the case of aesthetic requirements.
3. 1 / 4 round, small space, or affected by indoor environment, installation location, and other factors can be used in this way.
4. If the space is too small and the semicircle can’t be installed, you can only choose this smaller bow section.
5. Fan-shaped, irregular installation space, or if you want the duct to be artistic, you can choose this way.
Profile introduction under negative pressure:
1. Triangle, the specific method is to fix the fabric air duct on the top surface and stretch the air duct to the inverted triangle shape by stretching.
2. Rectangle with special support in the middle.
Of course, in the negative pressure state, even if the supporting or stretching effect is better, it will be affected by the negative wind, which will lead to the deformation of the air duct, so this section is generally not recommended. Generally, we will recommend the use of return air duct, which uses high-strength nano alloy materials and unique patented support technology to maintain the perfect rectangular appearance of the flexible air duct, To achieve negative pressure air supply, it can be used in combination with the tuyere and air valve to replace the traditional return air pipe in an all-round way, and it can be installed on-site by steel rope suspension.
