Fabric duct tips -- the treatment of fabric duct accidentally icing MX fabric duct adopts a unique anti-condensation technology. With permeable fabric, the surface of the pipe wall slowly penetrates out of the weak air flow, due to the effect of wind pressure, the hot and humid air outside the pipe can not contact the pipe wall, so the surface of the MX fabric duct will not produce condensation phenomenon. Fabric duct ventilation, condensation water icing, pipe icing treatment method

However, in a large number of market applications of fabric air ducts, there have been cases of ice problems in fabric air ducts, which only occur in low temperature cold storage environments. The reason is that during the operation of the air duct, the external water contacts the wall of the air duct, wets the fabric air duct, and frosts and freezes in a low temperature environment.


Causes of freezing:


1, during the installation process, the air duct failed to maintain a dry installation environment, the air duct was stained with water, and the air duct was turned on for ventilation and refrigeration without drying treatment;


2. The defrosting of the chiller is not sufficient, and a large amount of water is blown into the air duct by the chiller when the water is flushed.


3. The location design of the cold storage door is unreasonable, the cold storage door is frequently opened, and the door is not closed in time. A large amount of hot air outside the library enters the cold storage. When the fabric duct is not ventilated, the hot air will gather on the wall of the duct, wet the duct, and frost will be formed when the ventilation and refrigeration are re-ventilated.


Don't worry if it freezes. Solution:


1. Fundamentally solve the problem and prevent external water from contacting the wall of the air duct;


2. The convenience of fabric duct installation determines that it can be disassembled. The fabric duct is divided into sections, and each section is connected with a zipper. In case the duct freezes, the icing section is removed, dried in an outdoor high temperature environment, and then installed to the original position;


3, the fabric air duct has a uniform opening design, coupled with the flexible material of the air duct, if the icing phenomenon is not very serious, the ice can be broken, and then the broken ice can be shaken out from the opening.
