Durkeesox fabric duct dispersion system

In a regular project, there are lots of factors to influence the installation period, for example installation height, suspension mode, construction type, installation time (day or night), condition of the worksite and etc. So the installation period is uncertain. The average installation period is depends on the length, and the amount of the duct. For average calculate, the installation period of a 1000m fabric duct is 7 days, and increase in proportion to length. For example, a standard supermarket with 15000sqm, need 5 days to install with 4 labors.

The principle of the greener unit or the evaporative air cooler is using the exchange of cold water and air to achieve the cool down purpose. Because these kind of A/C equipment are without the refrigerating part, so the energy cost is much lower than normal Air conditioner. But the airflow transporting and air dispersion systems are the same as the normal air conditioner,.

So the DurkeeSox fabric ductwork system can be using to replace the traditional duct and outlets. But in particular, these kinds of air conditioner use the axial flow fan normally as the power source, within the same air volume, the ESP will be much smaller than the normal air conditioner, so the ESP needs to be particular check if the ESP achieves the requirement of the DurkeeSox fabric duct system while designing. The DurkeeSox air dispersion system will work perfectly with the greener unit or the evaporative air cooler system if the design is reasonable.

The pressure calculation of Durkeesox fabric air ducting system is basically as same as traditional air duct, including all calculationformula. The friction coefficient of Durkeesox system is almost the same as traditional spiral duct, only when we calculate the pressure of Durkeesox system can we ignore friction loss along the duct, what we need to do is the calculation of local resistance. For the Durkeesox system, friction loss along the duct will decrease as the air velocity inside the duct is reducing, the total friction loss along the duct is almost equivalent to static pressure regain, the difference is small even it does exist, besides, the static pressure regain is often more than friction loss along the duct. Sometimes, we even use PAD (pressure adjust device) to balance off some dynamic pressure. In complex system, it is requested to calculate pressure loss when elbow and T-connections are available.
